from the cathedrals of the rockies to the quiet glades in old growth of the appalachians. it's here in the parks we have the promise of stepping out of the hubbub of our chattering daily routine. it was 2008 when she sat out with her dog ella. her roommate julia from her college days had slept in that morning. >> she had left me a little note on the chalk board, taking ella. went hiking. not where, not when, not when i'll be back. it wasn't really anything out of the ordinary. >> meredith, like roomy julia, was a dog person. she doted on ella, her black lab mix since finding her at a rescue shelter.

>> she had two dogs growing up and one of her own. so we talked about it and she decided what she wanted, definitely wanted to rescue a doeg. finally found one loved her and brought her home. really it was the light of her life. >> julia the roommate didn't know meredith and ella were going 40 miles away to blood mountain. despite the creepy teen slasher movie name, blood mountain is a popular place to hike in the southeast. the famous appalachian trail to maine takes off from just south of here. back in buford, the roommate spent the day with friends and didn't notice meredith hadn't come back home since the next morning a back to work day. >> she would leave ella in my room and i would take care of her in the morning. i thought, ella isn't here. that was strange to me. i called her cell phone, it went straight to voice mail. i thought maybe she was at work. >> when did you become anxious? >> when i got to work, she worked with a good friend of ours.

and she called me and said, meredith didn't show to work. mare tij always went to work. >> reliable meredith wasn't where she was supposed to be. she called the sheriff's office and then she and other meredith friends assembled a search party. maybe she got hurt. do you know where eye i'm going hiking" would be? >> we had a few ideas. we had books she had, places she highlighted and kind of just started driving. >> the friends split up, looking for meredith's car at trailhea s she'd marked in her hiking guides. >> there were four of us in the car, trying to call park rangers, anybody that may have seen her or her car. then a friend of hers called her car, called us and said, i found it. there was snow on it p. >> the car was in a parking area at the base of blood mountain. >> we just drove as fast as we could. we knew, just that sinking feeling when we first saw it.

>> the friends raced up the blood mountain feeder path to the appalachian trail, but no trace of meredith or ella. so by night itfall the search became all the more urgent as a cold front moved in and temperatures on the mountain plunged below zero. at dayeak, trsday now, the friends were joined by deputies from the local sheriff's office. john kegel, just shy of retirement, was the agent in charge for the georgia bureau of investigation, the state's top cops. >> we received a request from a local agency to help with a missing hiker. >> the case of the hiker missing for two days didn't look good to the seasoned detective because of some disturbing items that had been recovered on the trail. what were the things found out on the trail area that you thought were alarming? >> a couple of water bottles, a dog leash and a police expandible baton. >> this is a piece of professional gear. >> it is. you see almost every police officer in the nation carrying

these things. >> did those artifacts, the water bottle, baton, found together tell you a story at all, or suggest something ominous? >> yes. we found those items in an area where the ground had appeared to have been disturbed. we became concerned that possibly a struggle took place there. >> meredith's water bottles, ella's leash, and signs of a struggle. nothing about the scene looked good to the veteran lawman, especially that expandible police baton that was found. he called in help. >> we eventually partnered with over 18 or 19 police agencies to help in the search for meredith. >> had her friends were naturally besides themselves. >> you know, your heart just broke because you think something happened, somebody had a weapon, and her stuff was there. >> so you're thinking at the very least she abducted. >> right. it wasn't something we could talk about until we could prove that.

>> the cops commandeered a park building as headquarters. >> we began getting information pretty quickly. >> from people who had hiked the trails that it day. >> right. >> and remembered her? >> right. we got news of a strange looking individual with meredith who also had a dog. >> thumbnail description of this other person. what were you hearing? >> strange looking, just a wiry kind of guy. >> older guy. >> older guy. we even developed a vehicle description, light van. >> the lead on the van came from this photo taken on a hiker in the blood mountain parking lot the night before meredith emerson went missing. a "be on the lookout" advisory went out for the guy driving a white van accompanied by his reddish dog. >> it is going to be a white male between the ages of 50 and 60 years old, approximately 160 pounds. it was described as he has bad dental, he had a dark reddish colored retriever.

>> we put out that information through the media in atlanta and actually got a call from somebody who sd, i think i know who this is. this mysterious stranger would prove to be stranger than anyone expected. >> i just turned white at one point. i felt the blood leave my face. >> meredith emerson had not been the only one missing in the forest. >> if she's still alive and someone has her, she's afraid. >> when "mystery on blood mountain" continues. distinct ch] the moment you realize a good backyard party requires a good backyard. at lowe's we have everything you need to create the outdoor space you've always wanted. get 20% off your purchase of two different select scotts products at lowe's. each day justin at work... walk. and after work. he does it all with dr. scholl's. only dr. scholl's has massaging gel insoles that provide all-day comfort. to keep him feeling more energized. dr. scholl's. born to move.

ella were two days missing on georgia's blood mountain early in a freezing january of 2007. her friends had alerted the authorities and people from all over the greater atlanta area were scouring the hiking trails. so many volunteers they couldn't use all of them. >> people just showed up and just said, i have a daughter who

likes to hike, i have a sister who could have been meredith easily. and they just volunteer their time. >> but the search in the national forest had become something more ominous than a lost hiker incident. meredith had been last seen in the company of an unsavory looking stranger, and law enforcement was about to identify him. the tip came from john tabor, an atlanta businessman. he was watching the continuing news coverage of missing meredith during his morning workout. >> when they started giving the description of the person of interest, my ears really perked up. hilton worked on and off fors him for years, first as a telemarketer and then independent contractor. he even lived for a while in this house taibor owned. what was the thought that's taking shape? >> the first thing that got my attention is where the event happened, where she went

missing, blood mountain. i knew that was a place he liked to hang out, that he had a dog with him. and most importantly was the evidence that they had found at the scene. i knew hilton always had an expandible police baton with him. >> the tip and a name quickly led to a georgia driver's license for 61-year-old gary michael hilton. investigators showed the photo to hikers who i.d.'d him as the scruffy mystery man meredith was seen. the man hunt was on. >> we put the face out. >> it's plastered all over the atlanta area. >> yes. the apb went well past the georgia border. hilton's name and picture were all over the regional news. light bulbs began going off to the south around tallahassee, florida's capital, when people saw the photo on tv. the search for gary hilton was about to widen. the person of interest in the meredith emerson case looked familiar to people who think they saw him about the time they learned of the sad case of

another woman who had gone miss being, sheryl dunlap, a nurse and mother. when sheryl didn't turn up for church one december sunday in 2007 and then missed her sunday school class, red flags went up. next door neighbor and friend tonya lad. >> sunday morning i turned around and looked at her usual spot and she wasn't there. >> she didn't teach her class? >> she didn't. >> immediately we knew something was wrong. that wasn't like her. >> everybody knew her agreed. 46-year-old sheryl was reliable, a woman solid in her faith and set in her habits. her fellow nurse friend and prayer partner, laura walker. >> she always liked to hear what we call our praise reports, like something good that p happened with a patient or a co-worker. >> when monday morning rolled around and tonya still hadn't been able to reach sheryl, she walked next door.

but the car was gone. i called her office several times and they hadn't seen her. >> sheryl's daughter-in-law tabitha called the sheriff's offi to repo her missing. >> when tonya said she didn't it show up work, i knew there was a problem. >> after the missing person's report was filed, the friends heard about a car that looked like sheryl's spotted on the side of the highway leading into tallahassee. they headed up there. >> it was sheryl's car and immediately they sent a deputy up there and just took over from that point. >> are you apprehensive? >> yes. i was very uneasy. i knew something was wrong. >> sheryl's car was parked well off the highway. annie white. >> it was pretty clear it wasn't some place she would have parked it as well as the tire looked like it had been purpose flattened on the vehicle. >> an abandoned car, a flashed tire. >> lord, where is she? >> searchers, law enforcement, volunteers began fanning out into the adjacent 57,000 acre appalachia national forest. all of them with dread in their heart.

>> i would be devastated if this happened to my family. i want to help. >> there were massive searches in town, thousands of people showed up to comb the woods looking for her. it was clear very early on that this was unusual for her. she would not have gotten in the car with someone. she just wasn't the person who would have disappeared. >> tallahassee democrat senior writer jennifer portman covered the story. >> we're talking about north florida in the panhandle area. people are bound by their schools, by their it family, their churches. >> and sunday school teachers with children and a grandchild don't go missing. >> that's exactly right. >> her friends and family were as baffld as the police. law enforcement was trying to put the pieces together. when they looked into sheryl's background, nothing jumped out at them. two sons, a long settled divorce, no boyfriends. then on tuesday, four days after she was last seen, the cops got her bank records. something was up. >> we found where some atm

activity occurred in leon county. that was a big break. >> yes. viing that jd in leon county, it was clear iwas not her. this was a male subject using her card. he was disguising his face so we knew at that point definitely that it it was probably not going to be a good outcome for ms. dunlap. >> the disguised man made three separate withdrawals of $700. the atm he tapped was in downtown tallahassee near the campus of the state u, miles from where sheryl's car was found. >> so you and the team stake out the atm machine. >> we stay there several days, day and night, watching the am. and he never came back to that one. >> the search for sheryl stretched on for weeks. >> a lot of us went out on our own and searched the woods and went to places we thought she could possibly be. >> but the more time goes on inevitably, the fear sinks in. >> i just remember sleepless nights, just -- because i'm thinking, if she's still alive and someone has her, she's afraid.

>> mid-december, two weeks after shierl disappeared, some hunters out training dogs in the national forest noticed a vulture circling in the sky above them. >> and they went to check it out and discovered the body. >> a female body missing its head and hands, a grisly fact not released at the time. you think this is someone trying to conceal the identity. >> very much. >> it took a dna sample from her toothbrush to identify the remains as those of sheryl dunlap. >> someone called and said, laura, they found a body. we pulled over on the side of the road and just -- >> that was it, huh? >> yh p. >> the awareness was there. >> it was surreal, the thing you hear about in movies. it it was so close to home that in our small community that something like this could happen. >> now, with cops in florida looking hard at gary hilton in the dunlap murder, and counterparts in georgia convinced that he had taken

meredith emerson, authorities started hearing about yet another national forest homicide, this one in north carolina. >> so theb you've got to be saying to your team of vectors, what do we have here? >> that's right. >> now we're wondering who we really have here and where is he? and, more importantly, where's meredith? do we have a killer running around loose in the national forest? >> concerned for meredith deepens, but her friends know something that man on the mountain couldn't. >> a blue belt in akeyed dough and a blue belt in judo. if anyone could survive, it was meredith. >> when "dateline" continues.

where was meredith hope emerson? could she still be alive somewhere out there in georgia's chattahoochee national forest? and did the 24-year-old hiker have a prayer if she were indeed in the clutches of mystery man gary hilton? the search on blood mountain went into a third day. >> we had the hope. i mean, we were there from sunup to sundown, plus. we were there through the night in the cold and all the searchers. but if anyone could survive, it was meredith. and if anybody could fight somebody like that, it was meredith. >> meredith's parents are flown in from colorado and joined the searchers. peggy bailey, a family friend, was their spokeswoman. >> let me tell you something, meredith emerson can do anything.

i have any hope -- she can run those mountains. she is a strong person. if anybody can survive this, she can. >> the missing woman was deceptively strong, not just an experienced hiker but an accomplished martial arts enthusiast as well. >> a blue belt in aikido and a blue belt in judo. >> so take you on at your peril. >> absolutely. she would fight you. she would come home and tell me, i threw this 220-pound man. beat him up today in class. >> by now, with half of georgia looking for this gary hilton, authorities outside tallahassee, florida, to the south were wondering about his connections with the missing woman there. it was then that the detectives got solid information about another killing in a national forest. >> we were in our command post and a detective walked in and

said that they had a case, took place in north carolina, involving a husband and wife, that the wife had been murdered the piska national forest. >> thadetective was workg an unsolved case that had cops in north carolina bewildered. david mahoney, a sheriff of transylvania county, a beautiful name with an ominous name that has nothing to do with fangs dripping blood. >> we have wonderful attractions here, all of those things with the slower pace of life is brings and keeps folks here. >> folks like john and irene bryant, who after raising a family retired here, far from the brutal winters of upstate new york and close to the hiking trails they loved. holly bryant is the youngest of their four children. >> they loved the outdoors. when they were first married, they used to go out hiking in the mountains. they would take us hiking and as they got older, they'd take the grandchildren out hiking, too. >> the bryants had a lifetime of outdoors experience, had hiked

all over the world. >> my father completed the appalachian trail, which is 2,000 miles, from georgia to maine. they've traveled extensively to new zealand and all through europe, all through america, especially the southwestern and northwestern united states. >> in late october, two months before meredith emerson disappeared, the couple set off on a day hike in the 500,000 pisgah national forest. no one heard from them for two weeks. >> they always let us know if they were going on one of their many trips so it was totally unlike them to just disappear. >> their son bob flew in from texas. >> the newspapers were around the doorstep. he broke into the home and found their breakfast was still out on the table, obviously many days old. and he knew something was

terribly wrong. my brother searched, went up and down every little back road throughout the park. >> he found their car at a trailhead in the national forest. by then, sheriff mahoney's office was involved. >> the rescue squad began a search, assuming that there had been some medical problem or so illss tt had llen upon them. >> in my heart, i knew that wasn't the case. there's just no way they would both be hurt like that. they were very, very experienced. >> unfortunately, it was not very long after we began that search that we discovered the body of ms. bryant. >> it was a sense of finality. i knew she was gone already, but that little glimmer, particle of hope was extinguished when they found had her body. >> irene bryant's remains were located 30 yards from where her son had come upon the car. she had been bludgeoned to death, but where was the husband? >> we began an even more

extensive search for mr. bryant. that search really involved the entire area of the pisgh national forest. >> within hours of discovering irene bryant's body, detectives learned $300 had been withdrawn from the bryants' accounts using an atm card in duckstown, tennessee. they had a picture from the machine. >> the man that had concealed his head and face that was able to successfully use the brients' atm. >> whoever making the withdrawal, it it wasn't 79-year-old john bryant. but time and geography were working against the lawmen. >> we spent weeks everywhere in that it entire area. we did everything om vehle patrol, atv patrolling, horseback, on foot, everywhere. >> john bryant had seemingly vanished from the face of the earth. the fbi posted a $10,000 reward for information, but the bryant case went cold. until meredith emerson loomed on the lawmen's radar.

>> our lead investigator began following that case, and immediately there were some similarities that we saw between the two cases. both of these incidents occurred on forest service land. we really felt like that the two were probably connected. we may go years without a homicide. this was very, very different. do we have a killer running around loose in the national forest? >> in georgia, the searchers looking for meredith emerson and her dog ella on blood mountain were hoping and praying that they weren't dealing with a homicide. >> do everything we can do to make sure that she -- if she's up there we get her out of there, get her out of there safely. if she's not up there do everything we can to eliminate that as a possibility and it continue the sfregs there. >> georgia authorities were compositing a profile of gary hilton who was started to look like a person of interest not only in the meredith emerson disappearance case but in it at least two unsolved murders in

the national forest. their findings were deeply troubling. coming up -- might a movie hold the key to this case? >> the premise of the movie is, we're going to te some wen into the woods and then, poof, they're going to be hunted down. >> maybe once investigators learn who was behind it. >> is gary involved in this? >> gary is helping me through . turn up your swagger game with one a day men's. ♪ get ready for the wild life a complete multivitamin with key nutrients, plus b vitamins for heart health. your one a day is showing. prestige creams not living up to the hype? olay regenerist shatters the competition. big hype. big price. big deal. olay regenerist hydrates skin better than creams costing over $100, $200, and even $400. for skin that looks younger than it should. fact check this ad in good housekeeping.

on blood mountain, there was still no trace of meredith emerson. her friend julia and the other searchers found no news to be good news. >> i think it might be a good thing, that she might be somewhere warm with her dog, you know, and somebody might just have her. or something like that. kind of makes me feel a little better knowing that we haven't found anything here yet. >> while hundreds of volunteer and depues scoured the forest for clues, detectives were trying to get it a handle on gary are hilton, the suspect in her disappearance and who was by now a person of interest in at least two murders. john tabor, hilton'ses former boss, gave investigators what information he had on his eccentric loner employee. tabor had known him for nearly a decade. >> the only interests he had in life seemed to be his dog and going out camping for extended periods of time in the wildernesses with his dog. he seemed to like that type of isolation.

>> hilton's dog dandy had been at his side since he started working for tabor. the former boss had come to regard hilton as a hair-triggered nut case. >> he often told stories of going to parks with his dog and he would end up in altercations with other pet owners. it it was always the same story. he would reprimand the other dog owners' behavior, then the other dog owner would get angry at him and verbally or physically assault him. so he was always the victim. >> for the first nine years hilton worked at his siding business. tabor recalled him as a good employee. then something seemed to snap. >> things started to change quite dramatically starting in 2007. >> what happened then? >> he just wasn't doing any work. i decided to go and just see what was going on over there. it was a very bizarre scene. >> how so? >> his physical appearance was quite different. he immediately smiled to show he was missing several teeth and he went on to say he took a pair of

pliers and removed some of his teeth. he said he enjoyed doing that because it frightened people. >> he seemed to enjoy showing himself in that matter, that ghoulish presentation? >> yes. he was very animated, very talkative. >> tabor fired hilton who then turned around and claimed tabor owed him money. by mid-summer 2007, the siding guy said he feared for his safety. >> he finally threatened to kill me. he made it very clear. >> tabor took those threats seriously. >> i immediately armed myself with a glock 9 millimeter and an ar-15 assault rifle. started driving a rental car so he wouldn't know what car i was in. >> he was your boogieman. >> absolutely. to not know what was happening, somebody maybe assassinate you. >> when the former boss went to the police with his story, it seemed to do the trick. >> within a day or two, he had packed p up all of his belongings and moved on. >> put all of his stuff in the van and took off. >> yes.

>> john tabor was relieved to see hilton in his rear-view mirror but he was nonetheless puzzled by the change that had come over the man. >> when you're around someone for nearly ten years and it's uneventful, nothing ever happens that suggests a demonic personality that apparently materialized somehow. >> tabor had part of the gary hilton picture, a criminal defense lawyer add more. sam rail had defended hilton years back on some morish beefs. >> we did a jury trial on a drug case, possession. he was accused on a misdemeanor of acting like a charity and he really wasn't a charity. he would raise money to help the little children. of course, he pocketed it. >> did he have a job to speak of or anything he did professionally? >> his job was scamming. that's what he did mostly. >> you knew hip as a con man basically. >> right. he was a little con.

>> when he got tripped up, he'd call on you. >> he did. >> rail, the lawyer, wears two hats. he's also a movie producer, not hollywood but more of the released direct to video school. his low-budget titles are more common seen in asian stalls than in your multiplex. this is his latest release. >> i can't do that! >> don't do it. >> shoot me! >> horror, gory? what's the genre? >> try not to make it gory, but at the end of the day a little blood, a little sex, a little violence can't hurt. >> as it turned out, cops on the meredith emerson case were particularly interested in rail's first movie, deadly run. he made it back in 1985 with the assistance of his scam artist >> the premise of the movie is we're going to take some women to the woodsnd then we're going to defend those women and the poof, they'll be hunted down

and killed. >> is gary involved in this, as a script writer or anything that formal? >> gary is helping me throughout and then helping me star, figure out how to be a serial killer. >> it these are ideas you're knocking around? >> gary has a dark side sometimes here and there. he wants to get involved in the movie, but he wants to make it darker and more horrible. he'd like to have more blood, more gore, have rape, more killings, things like that. i thought we toned it down and made a better movie, he suggested we do it up in in the woods. he helped me find some of the locations. we found the cabin. >> that cabin used inned movie happened to be in the chattahoochee national forest, just north of where meredith emerson went missing. he's around the table, as you guys collaborate on this film. how is he behaving around your group of movie people? >> when the movie is being made,

he's animated but interesting. >> he's not a loner? >> no. he's a loner. he's a psychopath. he's a sociopath. he's always trying to get one step ahead of the law. he's always doing something a little bit wrong but all my clients, they do that, too. >> it sounds like you're talking about kind of a charming guy. >> he was charming. he was personable. he was a fellow that you'd want to meet. >> which are all skills you need to be a successful con man if you're going to keep an edge. what the lawyer and movie producer had a falling out with hilton over all things but a dog. >> dogs seem to to be very important with him. >> they were. he wound up with my dog. >> what do you mean? >> i had a dog, nice little golden retreefr. had him in the backyard. all of a sudden i come back one day, the dog is gone. of course i'm very upset about it. then i find out that gary took the dog. >> he stole your dog. >> yeah. >> as the profile of hilton became clearer and became more

troubling, investigators looking for him and meredith were desperate for any lead on his whereabouts. and it they were about to get one. hear answered my cell phond his voice. couldn't believe it. coming up -- a trap is set to lure gary hilton from his hiding spot. >> i was trying to play it cool. >> and a dramatic new lead. could it lead police to meredith? >> she could be alive, and we just can't let up. in terms of treating sensitivity,

3 days is really fast. now the dentist is going to be able to provide that to their patients. sensodyne rapid relief in my opinion is a game changer. it's going to let the dentist offer their patient sensitivity relief in 3 days. it has a formulation that lays down a barrier of protection against sensitivity. within 3 days, say over the course of a weekend you're going to start feeling significant results. to say that it works in 3 days really is a big deal.

police were convinced the missing hiker meredith emerson was under the control of gary hilton somewhere in north georgia. the more they learned about the survivalist odds ball who was the person of interest in two murders in national forests elsewhere, the more they feared for her. a friend of meredith's family appealed directly to hilton. >> i hope that if he realized that this would be helpful, that his heart would be softened and turned to come forward with information. so, please, please have the courage to come forward. we need you. >> their next lead, the big one, came from an unlikely source, the suspect himself. three days into meredith's disappearance, gary hilton called his old boss tabor. >> i answered my cell phone, and i heard his voice. couldn't believe it. he pretended -- acted as if nothing was wrong.

>> he didn't let on that he was the subject of a man hunt? >> absolutely not. he aently had no idea. he apologized at length for his past behavior and on the terms of which he left, he said that he was ill and that now he felt better and he realizeed the errors of his ways and he was ready to get back to work. >> start elled but thinking past, tabor tried to lure hilton to an agreed-upon location with the promise of money. >> i was trying to play it cool, like i didn't know anything about what was going on. i told him that i would give him a check for $800. we discussed a place to leave the check. >> were you baiting that place he knew to come and show up? >> it was certainly my objective to get him to a place where authorities could apprehend him. >> the trap was set at a building owned by tabor where hilton had lived for a while. the s.w.a.t. team was dispatched. would hilton fall for the "pick up some money" ruse? and what about the missing woman? in your gut, did you think meredith was still alive?

>> meredith's name was meredith hope emerson. we all hoped she was alive. but, you know, the longer these things carry on, as time passes, you continue to hope but it diminishes after time. >> as the manhunt continued, >> as the manhunt continued, there was a glimmer of hope. friday morning, four days after meredith vanished, the u.s. marshal's service traced activity on meredith's bank cards. bank, 15 miles from the abduction site, and then again 50 miles south of the abduction site and then the next day 80 miles. these were attempts, where no money was taken. >> which suggests what? >> suggested that meredith wouldn't give him the right p.i.n. >> which also suggests maybe she's still alive. >> that's right. >> investigators had been able to trace the phone gary hilton used earlier to call his old boss john tabor to set that trap for him. that call was made from a restaurant 50 miles from blood

mountain. hilton it seemed was moving south toward atlanta. metro pd s.w.a.t. concealed themselves in and near tabor's building, the old drop point where tabor had promised him $8. >> you're staking out the location? >> he didn't show. >> no-show. >> we're still look gt and woeshing, where could this guy be? now we have this guy 50 miles from blood mountain. >> the veteran detective was talking constantly with meredith's parents, her father dave amor son. >> i appeal to everyone to search their hearts and memories for anything they can remember and do to help us find meredith. >> after i met the emersons, i knew that i had to tell them everything. i couldn't hold back any information from these two people. they were terrified. >> why did you take it personally? >> this case was a little bit different because not only me but the other investigators recognized the fact early on

that we have to embrace this family and tell them everything, even though what we were telling them was not good news. >> hilton, meredith, her lab ella. the tip line kept ringing with leads good and bad. then four days in, a friday afternoon, a shopper called to say that she'd found a black lab mix wandering around a supermarket parking lot. >> surprised to see any dog running loose in the parking lot. then to find out it's the one that meredith was -- it was her dog, you know, was a pretty big surprise and shock. >> she took the dog to an animal clinic where the vet was able to read an identity chip implanted in her. sure enough, it was ella. but ere was her owner, meredith? now eventsermovi quickly. right away came another tip. >> we get a call from a female acquaintance of hilton stating she had just hung up the phone. he had called her and wanted money. she commented that she -- she said, don't you know the world's looking for you?

and he hung up. >> hilton called from a pay phone at a convenience store near where meredith's dog had turned up. you have a living pet, a missing owner and a phone somewhere in the vicinity of this guy you believe is her abductor. >> yes. while the agents are searching in the area of the convenience store, they look in a dumpster. it was in the dumpster we found meredith's identification, her purse, bags of bloody clothing. at that point, we felt that this was not going to turn out as we had hoped. >> the purse, three bloody fleece tops. agent kegel and his boss gave meredith's parents the grim update. then, around 8:00 that night, still friday, not far from where tabor had set the trap for hilton, more than one elle-eyed citizen noticed a man emptying a white van. >> at the gas station up here, there is a white van and red dog wandering around. >> calls lit up 911. this one lasted for 12 minutes. >> dekalb, 911. >> i have the person of interest

in that missing woman case is at this chevron gas station on asher dunwoody. >> the man is there? >> the van is here. and i saw the man's face. i've been watching the news and i know it's him. i know it's him. he's emptying the stuff out of his van, looking around like he's guilty as sin. i can go take him down if you want. >> no, sir. stay right there. >> here comes the cops. yes. yes. >> police are there? >> they've it got him now. two cruisers pulled up on him. >> gary hilton was under arrest. detectives swarmed over the filthy astro van and inventoried his possessions looking for any clue to meredith's faith. a gbi spokesman updated the media. >> it's a missing person's investigate investigation right now. that's how we're pursuing it. >> take me inside your situation room when you get the news atlanta's got him.

>> we're very pleased that now we have this man, but we can't lose sight of the fact we don't have meredith yet. and the possibility that she could be alive and we just can' let up. we attempt to interview him. he refuseds. >> i'm waiving no rights. i want an attorney appointed to represent me. i want to speak with that attorney and i want that attorney present during questioning. >> cops had their man but not meredith. could they crack him, get from him the story of what had happened in the national forest? in your decades of law enforcement agent, have you ever had a session of interviews like this one? >> no. he was very straightforward and was very nonchalant. >> when "mystery on blood mountain" continues. so it's an extra 5% off on all this? yep, all this. all this. the moment you realize you can save big, even on the small stuff. you get an extra 5% off everyday

was charged with a crime against her, kidnapping with bodily injury. hilton was in custody but he was uncooperative, zipped up, giving his interrogators nothing on meredith's whereabouts or what he had done with her. >> meredith's middle name is hope and that's exactly what the lord gives us for her. so we are hoping that we're talking of meredith in the present tense and that we will be finding her and that she will safely come home to us. >> the searchers in the field, meanwhile, shifted their focus from blood mountain to these woods called dawson forest about 30 miles to the south. it was from around here that hilton had made those phone calls to his ex-boss. remember, by then, meredith's bloody clothing had been retrieved from a dumpster, not a good sign at all. but as long as there was the most remote chance she was still alive, the search was going to continue. but lead agent john kegel knew these vast woodlands very well, and he knew the otds of finding needles in haystacksment as he

saw it, he only had one option, repugnant as it was with, and that was to cut a deal with gary hilton. >> sunday morning we got him a lawyer and i went up and had a talk with the lawyer and essentially laid out our case. >> hilton's lawyer then conferred with his client. the district attorney was brought into the loop and a deal went down. hilton would plead guilty to murder, because that is what it had been, and then he said he would lead investigators to meredith's body in exchange for taking the death penalty off the table. nobody in law enforcement likes to make deals without holding their nose. >> we d to do it. you know, nto fded meredith, and given the circumstances i would do the same thing now. >> i'm guessing, agent, the situation in your interview room is, gary, you told us what did to her. now where did you put her? >> yes. and he told us. >> hilton was loaded into a vehicle and he led lawmen down a

trail in dawson forest. >> the body will be approximately 40 yards or 120 feet covered by leaves and brush. the head will be missing. >> where's the head? >> the only reason by the way the head was removed was forensically. >> yeah, right. >> a clearly shaken agent kegel told atlanta about the tragic outcome. >> at approximately 7:30 this evening the body of meredith emerson was discovered in a wooded area. the specific information given as to the location of the body was given to me by gary hilton. >> the kidnapping charge was anted up. >> mr. hilton is charged with one count of murder of meredith emerson. he has been taken into custody and brought to our detention center. >> in your decades of law

he was very straightforward and was very nonchalant about the whole thing. >> so you get down to the point where -- >> after his initial confession, gary hilton, the man of stony silence, became a chatter box, spilling out a story that sickened detectives who thought they'd heard everything. he began with meredith's

abduction here on a hiking trail on blood mountainment he said that he ambushed meredith and her dog ella as she came down the trail. it was a struggle and meredith with her martial artsz skills, as hilton tells it, nearly got the best of his. she disarmed him, taking away his knife and the police baton. >> i lost control of both the anthe knife. she was real quick with her hands and had no hesitation about grabbing weapons and everything. not only that, she was hard to subdue. fought like hell, man. >> hilton said they scrapped so hard they tumbled off the trail. separated by a few yards from the baton, the dog's leash, the water bottles, objects very importantly soon to be recovered. meredith meanwhile kept right on hilton. >> she started fighting again. i had to fight her again for several minutes. and her doing that is what got me caught. because if i had been back to the crime scene, just a few minutes sooner, just several

minutes sooner, i would have beat those people that found the bat and i would have picked it it up. >> he talks about fighting. >> yes. >> with meredith. that she almost took him. >> i don't really believe everything he says, but that part i believe. there's no doubt that she fought. you know, maybe it's a little bit that kind of gives you a little smirk to know she almost got him. she gave him a run for his money and i'm sure that he may have thought, i maybe should have chosen somebody else. >> eventually hilt hadden wore meredith down. by then they were way off the main trail. hilton tied his captive to a tree and doubled back to that site where he had been stripped of his weapon. the bay owe net was gone, lost on the forest floor and the hiker had picked up the baton. hilton returned to meredith. >> i told her i had a gun and, you know, i was going to shoot her as now. >> skirtthe main trailhe led meredith to his van in the trailhead parking area there he secured her with chains in the back of his vehicle and then proceeded to steal her bank

cards. hilton drove off to an atm in blairsville, georgia. >> he told detectives meredith had given him her p.i.n. numbers back on blood mountain. did meredith expect it would be all over for her if she gave him the correct numbers? in any case, she had given him bad information. >> and did didn't work? >> it didn't work. she's still telling me, it's it will work. must be a problem with the bank. >> hilton next tried to use meredith's cards a a bank 50 miles south in gainesville, georgia. again, no dice. he made camp that night with his captive in a remote spot in the forest. the next morning, hilton attempted to use meredith's bank card still again at an atm in canton, georgia. nothing. they returned to his hidden campsite. he held meredith altogether for four days in the woods.

and what nature of man is gary hilton? listen to the confession tapes about what he says about meredith's dog ella. he said he knew the dog had the identifying chip when he let the go in the supermarket parking lot. >> if i wanted to ensure that no one would have associated the dog with her, i would have killed the dog. there's no way i could do that. was too mucof a sty to kill the dog as he explained it. but ella's owner never had a chance. >> she was dead from the beginning. because i just told you, once you've done it, you're either going to kill her or get caught. there's no other solution. that sounds cold and cruel, yeah, it was. >> in his unbelievable cold recollection of the crime, hilton told meredith he was going to let her go after four days of captivity. >> i told her i'm going to take her and release her. >> instead, hilton went to the van, came back with a tire iron and bludgeoned meredith emerson to death.

in an attempt to thwart investigators, he decapitated and poured bleach over the body. this is gruesome beyond belief. >> yes. >> for what reason? >> i don't know. >> hilton had confessed to killing meredith emerson. but what about those other cases in the national forest? a woman in florida, the elderly couple in north carolina. >> he would not talk about anybody to us other than meredith. >> because you have to wonder when the switch was thrown in this man. >> i know. how many decades does this maybe go back? >> i don't know. do people just wake up when they're 61 and start to do these kinds of crimes the way he did them? you know, i would think not. coming up -- how a terrifying movie fantasy morpheinto real life. do you think that's the template for what he does, decades later? >> that's what's so chilling. meredith emerson went missing new year's day. less than a month later, gary michael hilton appeared in a georgia courtroom and pleaded guilty to her murder. meredith's parents were there. her mother susan addressed hilton. >> i believe you have nothing

more than a bully and a weak-minded coward who preys on others. he fancies himself a survivalist. well, anyone can see he's a scared little man on the run. >> the state honored the deal it made with the killer. no death penalty and he was sentenced to life in prison. hilton admitted nothing beyond the emerson murder. >> this is it the first time you've ever done anything like this? >> i'll let my attorney answer. >> by now, investigators from half a dozen southeastern states as well as fbi profilers were rummaging through hilton's past. by the time he was captured, he wasn't much more than a vagrant in a van, but his past was more complex. as an army veteran, hilton had earned an associate degree, gotten a private pilot license on the gi bill and been married three times before the wheels apparently came off. "true crime" author fred rosen has written 25 books. his latest is "trails of death" about hilton. >> to underestimate him is foolish.

this is a very dangerous person. >> according to rosen, he was shaped by a number of factors. hilton, who never knew his biological father, was raised by his mother and a stepfather, a horse trainer from argentina. do juvenile authorities run into young gary hilton along the way? >> when gary is 14 years old, he takes a gun and he shoots his stepfather. he doesn't kill him, but he wounds him very severely. and he's institutionalized. they put him in a mental hospital out in miami. >> hilton went to high school in hialeah, florida, played in a rock band and eventually joined the army. a cocky hilton made sure the cops who arrested him knew of his army service back in the '60s with a unit armed with tactic ittal nuclear weapons. >> i've handled atomic bombs. i did special p weapons. i've handled atomic bombs that damn big that weighed 70 pounds. and he bragged about his criminal con man past.

>> i've never worked full time in my life except for the army. i was a career criminal and lawful charity from '73 to '93, for 20 years. >> he's collecting money for charities of's a scam artist. >> exactly. >> and what about the dip into the movie business with the movie "deadly run" he helped make in the 1980s? >> this film where he's sending women out in the woods and killing them, hunting them -- it. >> i hope you like your little outfit i picked out for you, barbara. i think the look is definitely you. >> -- do you think that's the template for what he does decades later? >> yes, i do. that's what's so chilling to me about the whole thing, because in the millennium he'll make art into reality. >> you can hear the echos of this, huh? >> you're already beginning to see the lack of conscience. >> in his interview with the georgia bureau of investigation, hilton put forth a grandiose sense of himself, a renaissance

n of many hats.>> i'm a philoso scientist and i'm an artist. >> what do you mean artist? >> my art is my life and my art is weird. >> he's kind of a philosopher king. i'm an artist. and you poor dumb cops don't have the luxury of being able to think the big cosmic thoughts i do. >> he almost feels sorry for them that they can't keep up with him when he starts going about this, that and the other thing. >> hoping for crumbs of clues in those other open cases, murders in the national forests, the agents wanted to keep hilton talking. >> where all have you hiked? where all have you been in all over the united states? >> oh, i know what you're getting at, the unsolved murders. >> gary hilton thinks he's smart. is he? >> gary has an iq of 120, and that's considered to be way above average. >> the reason i'm so seemingly intelligent is that i alone amongst almost anyone, including you dudes, have time to actually stop and think about things.

>> he'll rattle on as long as someone will listen to him. >> yes, on any topic under the sun virtually, huh? >> yes. >> pick a topic. any topic. how about voluntarily convictology? >> don't you know the super volcano under yellowstone, there are over 70 super volcanoes? when it erupts it basically blankets in a cone the whole eastn seaboard of the u.s. under several feet of ash and would just destroy any civilization in that area. >> the fast-talking flimflam man was on display in some of hilton's home videos found in his van. here is hilton giving a cop that stopped him some lip. >> you tell me he you're the lawman. you're the law. i'm going to check it out. if it ain't the law and you're wrong -- >> come talk to me. >> i'm not talking to nobody. i'm filing and suing because you're interrupting my work. >> you hear gary braking about how smart he is, how well he does his job. but at the same time what you hear is an incredible narcissistic personality, which

is typical of serial killers. he sets up the camera, and there's gary going -- >> 171 pounds. >> he starts pumping up his biceps like he's arnold schwarzenegger. very narcissistic. >> so why were detectives enduring hilton's self-centered ramblings? clearly they were hoping he'd blurt out something about his involvement in the other unsolved cases in the national forests. but hilton was admitting to nothing. >> basely on our time line, you're basically telling me that you committed no crimes. >> none. >> between '97 -- or '95. >> '95. >> he had escaped the death penalty in georgia, but despite his denials, he remained the prime suspect in the murder of the elderly couple irene and john bryant. mr. bryant's remains were found inanuary in the north carolina forest. >> as a result of the investigation in georgia i was absolutely convinced at that

point that gary hilton was our suspect. >> but there was another open homicide case that seemed to fit gary hilton like a custom-made suit. down in florida, the body of sheryl dunlap had been found in a national forest. her at card stolen, the remains decapitated. detectives thought that fit hilton's m.o. to a "t." and gary hilton, still playing the smartest kid in the class defied florida to after him, all that time, all that money. >> if they want to spend a million dollars, 2 million, then another 2 million to get death and then another 8 million to defend the death penalty and get around to executing me 17 years from now when i'm 78 years old and i'm decrepit, hey, they can do it. >> two tough florida prosecutors it turns out would be the match of his defiant talk.

>> my belief is this is an evil, bad person and there ought to be a consequence in life to evil acts. coming up -- justice for sheryl. the hunt for evidence begins. >> she took the floors up, the seats out. >> when "mystery on blood mountain" continues. jimmy's gote room smelling like sweaty odors. yup, he's gone noseblind. he thinks it smells fine, but his mom smells this... luckily for all your hard-to-wash fabrics... ...there's febreze fabric refresher. febreze doesn't just mask, it eliminates odors you've... ...gone noseblind to. and try febreze unstopables for fabric.

dunlap whose partial remains were recovered two weeks before meredith emerson went missing. hilton was defying authorities in georgia to make the charges stick. >> if they want to spend a million dollars, 2 million, to convict me and then another 2 million to get death, hey, they can do it. >> leon county florida state's attorney willie max had heard enough and indicted had hilton for the murder of sheryl dunlap. >> he's gone away for life. he'll be leaving georgia corrections in a pine box. why does florida need to go to the expense of a death penalty trial? >> my thought is this is an evil, bad person and there ought to be a consequence in life to evil acts. i don't think murderers ought to be cheaper the more you do >> with the dunlap case looking like a carbon copy of the meredith emor son murder, you

may think it would be a gimme. far from it. they could not enter the evidence about the erm son murder or the movie "deadly run" or that he was the prime suspect in the murders of an elderly couple in north carolina. annie white was part of the team charged with making the case. months earlier, the cops had developed a partial chronology for sheryl dunlap on the saturday she vanished. >> we started receiving calls, we saw her at walmart, saw her here. we started backtracking those to try get the time line. >> the investigators knew that sheryl's morning had include shopng in tal it hass see, cashing a check at a bank and using a library coer to se an e-mail to had her son in the army. they even had a last sighting. witnesses identified sheryl as the woman peacefully reading a book at this popular spot in the national forest.

charred piece of skull and the bony fragments of a human hand in the ashes of a camp fire. >> they were badly burned. >> little camp fire pit kind of thing? >> yes. he had actually done a pretty good job of covering it p up. he had covered it up with straw and took mtoeasureide his tracks. >> t fire had en so thorough it was impossible to extract da from the dons. whoever killed sheryl dunlap had gone to extraordinary lengths to eliminate any physical evidence. there was one thing about tracking the odd guy with the red dog that they had going for them. state's assistant prosecutor. >> fortunately for the investigation, if somebody saw gary michael hilton they remembered him. he's got that kind of a face or presence that you don't forget. once we had the description, we had tons of witnesses coming forward. >> and investigators had those home videos of hilton to screen as well. >> last time it was suwannee that was out here.

>> i don't think so. >> watching the videos was very educational because i saw him by himself. i saw him with other people. >> people like this restaurant manager suffering a rant from

but, despite all the investigative work by multiple sheriff's offices and the fdle, no witness came forward to put him together with sheryl dunlap. the nurse's remains were in such poor condition they told investigators nothing about how she died. but there were thousands of other pieces in the puzzle investigators were trying to solve. hilton's van jammed to the roof with hundreds of items was trucked to the florida department of law enforcement crime lab. >> our crime scene analysts spent day and night literally, weeks. >> that van was a mess, right? >> she lived in that van for weeks. she dismantled that van. >> all that evidence from the van was added to items recovered from the dumpster outside atlanta where hilton was

gary hilton's trial for the florida murder of sheryl dunlap began in february, a little more than three years after he had pleaded and skatd the death penalty in georgia. but there was no chance a plea deal in this tallahassee courtroom. he might be doing life in georgia, but this was a capital murder case. if convicted, hilton could die by lethal injection. remember, lead prosecutor georgia cap elleman couldn't tell the jury about hilton's conviction in the emerson murder or mention he was the prime suspect in the north carolina double homicide nor tell the jury anything about the slasher in the forest movie "deadly run" that he'd help make. >> ms. dunlap found herself in a situation and ultimately came to an end that is something we only think about in nightmares. she spent two days with mr. hilton before he decided it was time to murder her in cold blood, chop off her head and hands, and dump her body.

>> after her opening statement, the state built the brick and masonry are of its story on the time line investigators had so painstakingly assembled. an attorney hiking with her husband in the national forest ln sinks that saturday morning remembered seeing sheryl. >> i looked at her, and i said, it it's peaceful out here, isn't it? and she looked at me and she nodded and she smiled and then she exited the boardwalk. >> then a parade of witnesses testified to seeing hilton out and about in the national forest. there was the motorist who noticed a man near sheryl's car with a flat tire. >> how confident are you that mr. hilton was the man that you saw at that vehicle? >> very confident. >> others remembered dandy, the man's good-looking reddish retriever mix. >> show you what i've marked as state's exhibit 37. >> that's it. >> that look like the dog you saw that day? >> yes he.

>> a picture of hilton's dog dandy, exhibit 37, was looking to be the state's key piece of evidence. >> quite sure that's the dog. >> another testified about being flagged down by hilton on one of the forest roads. hiltden was looking for a jump-start for his van. >> i'm an old southern boy. he looked like a little yankee man to me. >> and hunters, too, identified the old guy with the nice dog. >> he was flagging us down like it was an emergency or something. >> what the prosecution couldn't tell the jury was exactly how sheryl had died. a county medical examiner had to work with severed remains that had been exposed to the elements he thought for at least a week or more. >> are you able to tell this jury how this woman died?

>> no, ma'am. >> not a cause of death. but what the prosecution did have was forensic evidence galore. hundreds of items recovered from his van and from hilton's suspected campsites deep in the woods. >> two items here, duct tape with hair and another piece of duct tape or masking tape with hair. >> one of the items was hilton's video camera that was retrieved. he tried to delete. >> i was able to recover those previously deleted files. >> florida department of law eens forcement lab experts had been able to salvage the audio hilton did not want the world to hear. and with good reason. this is gary hilton two days after sheryl dunlap's disappearance singing into the camera microphone and gaving with the dog dandy. ♪ dan, dan, dan, we're doing it, boy ♪ >> it sounded as though he was confessing to the dog. >> i killed her. >> a hushed courtroom listened to the monolog. >> this is the park.

yeah, but first i've got to go hide it somewhere else. >> the state's forensic people introduced evidence about sheryl's slashed tire, a tool mark expert said the bayonet recovered on blood mountain in georgia was an exact match to the sharp object that caused the puncture in florida. but the say good night evidence was the dna evidence. joellen brown spent two years testing more than 250 pieces of evidence in the case. brown told the jury she was able to match sheryl dunlap's dna to blood on two of hilton's sleeping bags and on the shoe louis r laces of his hiking boots. >> the major donor matches sheryl dunlap. >> jennifer portman was in court every day. so how good or bad is the forensic evidence against gary hilton? >> when the prosecutor present ared the da evidence and the

sleeping bag with sheryl dunlap's blood on it and gary michael hilton's blood on it, you could just see the jurors, for them, you saw it in their eyes. they knew. >> and with that, after six days of testimony, the prosecution rested. now the defense, holding a very poor hand, would have to fight for gary hilton's life. its case was brief. lead attorney inez super-called only one witness. >> do you wish to testify? >> no. in terms of treating sensitivity,

far more vigorous than her limit ared witness list may have suggested. >> we have absolutely no evidence, no direct evidence, that mr. hilton committed murder. >> the jurors began their deliberations. capelman and her boss waited for the verdict. >> you've done a lot trials. is this just another day at the office? >> no. >> oh, no. never. when you're waiting for a verdict, your palms are sweaty and your heart is beating and you're very nervous. >> i can tell you i've been doing it 35 years now. it's never gone away for me. there's just -- oh, you'd really like to throw up while you're waiting. until you hear it read, it is tense.

the trial of gary hilton for the murder of sheryl dunlap had taken seven days. the jury needed less tlan 3 1/2 hours to reach its verdict. >> we thjury fd follows --s cou one of the indictment, the defendant gary lton is guiltyf rsdegree murder. count two of the indictment -- >> gary hilton was found guilty of the first-degree murder of sheryl dunlap. guilty on all counties except car theft. the same jurors would soon reconvene to decide if hilton would die by lethal injection.

he had dodged death in georgia and now it was time to see if he could do it again. >> this man, mr. hilton -- >> assistant state's attorney georgia appleman had gotten the initial conviction. >> what words did you use to describe this guy? >> he a's a psychopath and there's crazy sick and crazy mean. he's just crazy mean. he's intelligent, a college graduate. he was a member of our armed forces.

he's probably smarter than everybody sitting in this room. >> there were different rulz in this it the penalty phase. unlike in the trial, prosecutors were now able to disclose to jurors that hilton murdered meredith emerson on blood mountain and state's attorney willie megs did just that, calling to the stand georgia bureau of investigation agents who had worked on the emerson case. >> you indicated it that ms. emerson's body was nude. did gary michael hilton tell you why it was nude? >> he did. he basically stated that he had removed the head and stripped the clothing for forensic purposes. >> megz was able to introduce portions of those chilling interviews that hilton gave the authorities in georgia. >> once you've taken someone, you're either going to kill them or you're going to get caught. it's as simple as that. >> that's where you started getting the information about

emerson -- >> that's the first time the georgia information was allowed in. >> correct. that's when you really start seeing the jurors taking in the enormity. then you really see the impact of all of this coming through. >> good morning, ladies and gentlemen. robert freedman was the defense's lead attorney in the penalty phase. his strategy was to portray hilton as so mentally damaged to be incapable of responsibility for his actions. freedman began with a pet scan expert who testified about traumatic brain injury he had suffered as a 10-year-old. >> he was taken to st. joseph's hospital in tampa and given 200 stitches. and this is an example of the murphy bed. >> and jurors that's not all the defense's expert continued. hilton was abused as a child and he he lashed out as a teenager. a defense neuropsychologist tested hilton who it it turns out is as bright as he thinks he is.

>> on the wexler intelligence scale he scored an overall verb iq of 120 which puts him in the upper 10% or so of the population. >> another psychiatrist diagnosed him with multiple diagnoses. >> we call it an unresolved edible complex. a child can grow up with this emptiness inside of them. >> to top it off, the defense continued, hilton was self-medicating with prescription drugs. >> ritalin and effexor will basically push you over the line. >> the defense then treated jurors to gary hilton, this is your life. a saga of abuse, neglect, and injury. it included an audiotape of hilton's late mother talking about how as a teenager hilton had wounded his stepfather. >> he said, shoot me, shoot me!

go ahead, shoot me! i dare you to shoot me. gary shot him. >> in the legs or -- >> the lower part of his stomach. >> a junior high girlfriend testified that gary wasn't a bad guy back in the day. >> he was funny and outgoing and smart. >> the defense rests. >> once the defense rested, willie megs called his rebuttal witness, a clinical psychologist to revisit the essential issues. >> did mr. gary hilton know right from wrong? >> my opinion is, yes, he clearly knew right from wrong and clearly he knew the criminal nature of conduct. in my opinion, he is a psychopath. that's what generated the murders and nothing else. >> the attorneys made their final appeal to the jurors. >> i'm going to ask every one of you individually to go back in that jury room and vote to recommend that gary hilton be put to it death. >> on behalf of mr. hilton, i'm asking all of you collectively and individually to recommend a life sentence in this case.

>> the jurors then retired to deliberate nothing less than whether gary hilton should live or die. coming up -- another haunting question -- were there more victims out in the forest? >> i personally believe there are. and a legacy. >> she's really the hero. it was through her efforts that we were able to catch her killer. >> remembering meredith hope emerson. and coming up monday on "i have antivirus, but my computer's still slow..."

the same jurors who found

gary hilton guilty of murdering sheryl dunlap were now trying to decide if they should recommend hilton spend life in prison or be put to death by lethal injection. their life or death debate lasted an hour 20 minute >> the majority of the jury by a vote of 12-0 advise and recommend to the court that it impose the death penalty on gary michael hilton. >> hilton sat expressionless as the results were read. two weeks later, an equally emotionless hilton listened as the judge pronounced his sentence. >> it is ordered and adjudged that you gary michael hilton be sentenced to death for the murder of sheryl dunlap. may god have mercy on your soul. >> in april, gary michael hilton was sent to florida's death row for the murder of dunlap. last month he was shackled and sent to north carolina and indicted in federal court there for the murders of john and irene bryant. the government alleges the serial killer murdered the

elderly couple in october of 2007, shortly before killing sheryl dunlap and meredith emerson. hilton pleaded not guilty. the forensic team from florida that had helped convict him there is expected to testify. hilton faces another death sentence in the federal trial. law enforcement officials from across the southeast have now met with hilton multiple times in an attempt to find out how many more of his victims there it might be out there. you believe there are four deaths connected hire. >> at least. >> you think there are others? >> i think there's certainly the potential to be others. i don't know we'll ever know for sure unless he tells us. >> so far hilton is sticking to his story, that he started hunting as he describes it in october of 2007, that there were no murders before that. the pain and suffering of the families of hilton's victims and suspected victims dulls but never ends. >> he's taken so much from me and my family. what can you say to someone who would murder two wonderful people for $300 and meredith emerson, a beautiful young lady

and sheryl dunlap and very possibly many more? the man is not even what i think of as human. he is something else, a true psychopath who needs to be put where he can never harm anyone else again. >> for sheryl dunlap's friends and family in florida, hilton's conviction provod colicting feelings. >> and think, believe it or that sheryl would want us to forgive. and when i went into the courtroom and i actually saw him, my thought was not that they put him to death or this or that. i was glad he was off the street. but i have to forgive gary hilton. i have to. >> tabby, in the family it was a death case and the jury recommended the death penalty and that was the sentence.

does it matter to you? >> we were pleased with the outcome, yes. like laura said, he's off the streets. he's not able to hurt anyone again. yes, i think it matters. >> and there are regrets on the part of the officers who investigated the hilton cases. could there have been one tip line that had come in sooner? could there have been one fragment of information we could have put together more quickly and spared her? >> there hasn't been a day go by since then i haven't thought about meredith emerson and what we could have or should have done differently. but, see, she really is the hero. she did the best could in hopes we could catch up. it was through her efforts we were able to catch her killer but also the killer that was responsible for the killing of sheryl dunlap. >> in georgia, for meredith emerson's closest friends, it's time to forget about gary hilton and remember her. >> he took our friend. he took a daughter, a sister. but he can't take her memory. he can't take the things that we love about her away.

>> there is, they say, important work to be done. >> we started an organization in her memory. >> julia karen bauer, meredith emerson's one-time roommate in georgia has founded along with others something called right to hike, advocating hiker safety. >> don't want anyone to go through this, bring awareness, make you think about going hiking by yourself twice, take a friend to be a little safer. >> the organization founded by meredith am emerson's friends has sponsored events with a huge turnout of people and dogs. meredith's dog ella lives today with her parents in colorado. >> any event that we ever have at right to hike, just seeing people come and say, i never met meredith, but i feel like i know her, and i wanted to come out and sue pour. that was the biggest thing, the community outreach after everything happened. >> right to hike has aided humane societies, educated hikers on safe practices, and

put cell towers on trailheads. >> oned big things that we realized very quickly on these trails, that our cell phones didn't work and meredith had her cell phone with her and that didn't help her. >> and if you ever hike blood mountain, you just might notice a little sticker there as you head out. "remember m.e.," meredith emerson. she most of all would like you to enjoy yr day in the ouoors. >> just really enjoyed bei out with nature and watching ella run through the forest and play with other dogs. i think it was just a really peaceful place for her to be. >> people go to these places to relax and get away from everyday life and enjoy the outdoors. and they should continue to do that. these are some of the safest places there are to go.

i'm craig melvin. >> and i'm natalie morales and this is "date line." there's this pile of leaves, and it's where everything else is clear and flat. my heart is racing a million miles an hour. i was using my boots to move leaves, and that's when i screamed this blood-curdling scream. >> nique leili, a corporate executive who made time for romance and her three daughters. >> she was the best mom. >> then she disappeared.
