>> this woman is a doctor, but not the usual kind. >> see where the bullet is on the x-ray? >> her specialty, deadly mysteries. >> still not there, huh? >> i don't find anything. >> as a medical examiner, she cares deeply about her patients. but they'll never recover. >> we want to determine the cause of death. >> these lives may have ended, but their stories are just beginning. >> my job is to have the victims speak to me.

>> "dead men talking: the case of the double homicide." >> humans can be quite creative in the ways they can think to hurt each other and in the ways they can actually end up causing the death of someone else. >> crime investigation is a team effort, according to dr. tracy corey, chief medical examiner for the state of kentucky. she's one of several investigators who work to unravel the mysteries behind the deaths of the victims who arrive in her autopsy room. >> i like puzzles, and every single case presents its own mysteries to try to figure out. >> you'll see all that it takes to solve one of those mysteries. a horrific crime. two lovers found shot to death in this car in an alley.

our cameras are allowed rare access to the death scenes, the investigation, the autopsies, and wherever else the clues and leads take the police. as in the tv drama "csi," there is a cast of fascinating characters who join forces to solve this crime. there's dr. corey, the medical examiner. a doctor of forensic pathology, she performs autopsies on all suspicious and unexplained deaths. >> my job is to let the victims speak to me, let the victim tell me what they can tell me through the physical evidence. >> there's the coroner, ron holmes, an elected law enforcement officer who once interviewed serial murderer ted bundy. his job is to examine and control the bodies at the scene. >> the crime scene belongs to the police. the body belongs to us.

>> there's the detective, chris middleton, working around the clock before the trail goes cold. his motivation, to solve the case for the loved ones the victims left behind. >> i've got a duty to their parents, brothers, sisters and children to find the person responsible for their death. >> and there's the mother of the victim, angela thompson. her daughter was gunned down in the alley. she will help investigators any way she can. >> i just want to know why. why? why would you want to do this? why? >> it all begins with a static-ridden radio call from police dispatch. >> 425 charlie, go ahead. >> ems, vehicle found. >> 10-4, you're in the alley? >> right behind 946 beecher.

>> coroner ron holmes, homicide detectives, including chris middleton, and forensic experts race to the scene where they find two dead bodies inside a car. >> as best we can tell right now without opening the car up, there's one person's been shot in the side of the head and the other person we can't tell yet because of the positioning. >> a young man and woman slumped in the front seat. troubled lovers? maybe. >> first thought was murder/suicide. he shoots her, and then he shoots himself. >> holmes, a big fan of his namesake, sherlock holmes, deduces that the car has been here for several hours. >> it snowed after the car was parked there, because there's no tracks in the back of the car. >> it's a generally safe, working-class neighborhood. the alley is across from a park, about a mile from the famed

churchill downs racetrack. >> this particular area around here is very, very low in violent crime. >> holmes and other investigators peer into the car, trying to avoid compromising the case. >> we certainly don't want to interfere with any evidence that's already there, any physical evidence. we are concerned very much about the blood spatter inside, any prints on the car, on the door, on the window. >> holmes, a former criminology professor, is the author of 20 books on crime. one subject he found most disturbing, serial murders. as nightfall approaches and temperatures plummet, the alley is too public and conditions too uncomfortable for investigators to do their work properly, so the coroner and detectives decide to move the death scene, literally. >> we'll take the car to a different site and process the scene there. >> and in a television rarity, you'll get to see the move.

here, it's gently hoisted up the ramp onto a flatbed truck. before its ride across town, the car is wrapped in a tarp to conceal the lifeless passengers from prying eyes, for it will be a slow procession through louisville, forced to inch along with the rest of the rush-hour traffic. less than an hour later, the car with the victims still inside, is lowered into a warmer and brighter location, a police garage normally used by the auto theft division. >> we brought that vehicle to this location so we could do a more thorough and i guess better search of the vehicle for evidence. >> working with detectives, coroner holmes and deputy coroner joanne farmer, help nail down the victims' identification.

the man through his car and later his driver's license. >> his i.d. is there. >> the female victim has no i.d. on her, but the police are receiving leads about a missing 18-year-old girl. they believe they have a match, based on her tattoos and clothing. >> the girl's supposed to be wearing a white jacket, white boots, blue jeans. >> uh-huh, yeah. >> she has on those white boots they were talking about. >> the cops and crime scene technicians swarm around the car, taking photographs, searching for clues and checking for fingerprints. the coroners are now backing off their murder/suicide theory. >> i think it's going to be something else, don't you think? >> oh, yeah, yeah. >> somebody else could have shot both of them. >> i see a personal vendetta here. the wounds are very personal. but now i think it's a homicide. coming up, forensic pathologist dr. tracy corey ultimately will determine the cause of death and provide answers to investigators and families alike.

on a friday afternoon in louisville, two bodies have been found shot to death in a car, and police have an initial theory. >> especially with a female and male, a lot of times, you may think it's a murder/suicide. >> but after a more thorough investigation of the car, everyone is now leaning instead toward a double homicide, likely a shooting from behind. a bullet casing is found in the well of the back seat. >> the shell casing in the back seat looked like a small caliber. >> meanwhile, the coroners supervise as the bodies are pulled from the car. first, the man behind the wheel. crime scene technicians place paper bags on his hands to preserve evidence, possible dna and gunshot residue for the next

day's autopsy. >> we will do it all just to make sure that nothing escapes. >> as they examine the bodies, there's no joking, no gallows humor. there's great respect shown for the victims, for their humanity, and maybe, says holmes, their souls. >> yeah, the person's dead. and, you know, whatever is after that, you know, is your own belief, but we just don't know how long it takes. if they've been dead for 15 minutes or they'd been dead for an hour, are they completely away? >> go ahead and bag them up. >> yeah. >> zip them up. >> minutes later, investigators unfasten the girl's seat belt to examine her. the deputy coroner finds what appears to be two gunshot wounds in the back of her head. >> definitely doing a quick once-over here. we want to get them to the morgue to preserve them, you know, in the cooler as quickly as possible.

>> investigators also notice something suspicious on her back. >> no, there's a burn. it's a burn. there's a burn here. >> and speculate she might have been tortured, until they figure out what really happened. the car seat heater remained on after the shooting and burned her. >> put the seat down and the medical examiner will confirm that in the morning. but i believe that's what it is. >> while the bodies are wheeled out to be taken to the morgue, investigators stay behind to track down more leads. >> the first 48 hours here is crucial. it's still a hot topic in the community. you're getting very good tips from people in the community. >> meanwhile, assistant coroner joann farmer, a former nurse who's retained her warm bedside manner, will talk tonight to family members. >> making death notification is absolutely the hardest part of our jobs. we can't make a difference as to what has happened here, but we can orchestrate how the families are handled.

>> now at her coroner's office, joanne comforts the father of the 18-year-old girl. >> do you have any questions for me about anything about this? you know, they were found in the car -- >> i'm confused with everything. >> i know you are. >> she does her best to ease the blow of his daughter's sudden death, explaining that the teenager did not suffer. >> i'll tell you that. it was instant. she would have lost consciousness immediately from that. and i'm just so sorry to have to talk to you about this. >> overnight, the body of his daughter has arrived in the morgue, in the same building as the coroner's office. she and her boyfriend will be autopsied in the morning by the medical examiner, dr. tracy corey. >> the good forensic pathologist simply lets the victim tell their story. >> those examinations, those victims' stories, will be dr. corey's only chance to help the criminal investigation, perhaps

to find evidence to help trace the killer. >> i basically have one bite at the apple. i have to think of answers to questions that haven't even been asked yet, because i have only one opportunity basically to collect all of the physical evidence that i think i need. >> dr. corey is about to find out if the killer left behind any clues. coming up -- >> i think we're going to recover the bullet from right under there. >> an inside job. the autopsy as you've never seen and heard it before. s on optimi. it's what sparks ideas. moves the world forward. invest with those who see the world as unstoppable. who have the curiosity to look beyond the expected and the conviction to be in it for the long term. oppenheimerfunds believes that's the right way to invest... ...in this big, bold, beautiful world.

every single case presents its own puzzles and its own mysteries to try to figure out. and when you can figure out a particular case and put the whole picture together, that's very rewarding. >> dr. tracy corey, kentucky's chief medical examiner, is the star of a real-life drama, which plays out daily in this room in an old converted hospital in downtown louisville. >> the other thing that i find personally rewarding is when i can help families find the answers that they're seeking. >> her professional life has some similarities to the highly stylized depictions in shows like "crossing jordan" and "csi." mostly, that each day at autopsy, she faces death in many of its most violent forms, the tragic accidents, the suicides, the murders. >> the types of cases that forensic pathologists deal with are generally completely unexpected. you know, this morning at 8:00, their loved one was alive, they thought.

and yet at 8:10, they have a knock on the door or a phone call that indicates that this person is no longer on this earth. >> we have some breaking news out of south louisville. >> police say two bodies have been found in a car in the 900 block of beecher street. wave 3 investigator eric flag joins us live at the scene with the very latest. >> it's early saturday morning. >> i'm never sure when they're going to -- >> the weekend for most of us, but a workday for dr. corey. yesterday's breaking news, the double homicide, will be today's caseload and her first chance to aid the murder investigation. >> i think there are very few people who go into medical school who would want to see what we see on a daily basis. finish all that stuff, the person you were following? >> uh-huh. >> okay. >> but before work, some early morning family time with her husband and one of her two sons. donald burbrink is a louisville police captain, who says his wife is like a sharp detective,

relentless in pursuing answers for victims' families. >> she could have been a very, very good detective. she's almost like "columbo," peter falk, one more question. one more question. it's like, please be done. please be done. please don't ask any more. >> wear your heavy coat, please. >> okay. >> but at home, she's like any mother, a worrier. >> bye, mom. >> maybe even more protective because of the danger she sees every day at work. >> bye. a job like this makes you more aware of hazards, risks, and worst-case scenarios than if you work in a library or a law office. >> as she arrives at the morgue, dr. corey knows exactly what's in store for her. >> i pretty much know what i'm going to do. you know if you have a gunshot wound case that you're going to be doing x-rays.

>> from the start, dr. corey is cool, focused and efficient. the x-rays showed two bullet holes in the victim's head. her goal is to find the bullets and whatever other evidence will aid the criminal investigation, and then return the body to the victim's family as quickly as possible. >> this is tracy dictating 0799, 0799. >> the young woman from the car in the alley has been given a number, 0799, the louisville office's 99th autopsy of 2007, and she has a name. >> body identified as ashley typo yennous. the body is that of a normally developed, normally nourished female, appearing around the given age of 18 years. >> that's only a year older than dr. corey's eldest college-bound son. but she says it's important to ignore such observations when she's working. >> if i get caught up in the tragedy of the moment, then i'm basically doing a disservice to

the decedent and to their family. the best way to help the decedent at this point is to remain objective. >> on this day, her job is clear cut. >> we want to determine the cause of death. in a case of a gunshot wound case, we're going to recover the bullet or bullets. the posterior aspects -- >> whatever she finds will be turned over to investigators. >> my role is to do a complete examination, to gather all of the physical evidence that i can, to document that physical evidence to the best of my ability and by doing so, that allows the victim to tell me the story and then i should tell the story to those people who have the right to know. >> dr. corey finds that the victim's wounds provide clues, clues that will help investigators determine a key detail -- how close the gun was to the victim.

>> we can, by looking at the skin surface, get an estimate as to how far away the muzzle was from the skin surface when the trigger was pulled. she shows what's called stippling or tattooing, which is when the burned and burning gunpowder particles strike the skin surface and create little injuries. it also told me that the muzzle of that gun was relatively close. it was within a couple of feet away from her when that trigger was pulled. well, what we're going to call this is intermediate range. that can be obviously crucially important in the overall case. all right. right lung. >> for as long as she can remember, cases, criminal cases, have been part of tracy corey's dna. she's the daughter of two kentucky judges, but she joked that she didn't start out wanting to be either a lawyer or a doctor. >> no. you know -- when i was 4, i wanted to be a bride. i thought that was a profession. i thought you could do that for -- you know, walk around in a white dress all the time. >> instead, her daily fashion is blue scrubs and a plastic face

shield. her profession, helping to solve mysteries, the fulfillment of her longtime fascination with biology and the criminal justice system. >> well, i was always attracted to the biologic sciences. >> and for most medical students, forensic pathology is the road less traveled. to become a medical examiner, she was required to do an additional year of specialty training. >> you do an extra year of training to make less money. so a lot of people who might otherwise be attracted to it then say, well, why would i want to do more training to make less money? that makes no sense. >> so why would she? >> because it's a great profession. because it is extremely interesting. because it is never boring. and because it can be very rewarding in that you're providing a public service. >> not only does she aid the police, she also helps grieving

family members by determining the exact cause of death. >> they're still going to be grieving, but if i can help answer questions for them, that puts their mind at ease. hopefully, it will eventually help them accept what has happened and be able to then move on with their life. you see where the bullet is on the x-ray? >> even though she strongly suspects the gunshots to the head killed ashley, dr. corey also examined her main internal organs and sent samples to the crime lab. >> we want to see if there are any other injuries present. >> anything and everything that could help tell ashley's story. >> our problem is we don't know what may become important later. unlike in clinical medicine, i can't call the patient back and say, oh, well, now i want to do this test. >> because she doesn't know what unexpected twists and turns the homicide investigation might take. >> yes. >> so dr. corey makes sure everything is painstakingly photographed and documented as potential evidence.

the examination involved an array of knives, scalpels and even this tool, known as a vibrating saw. dr. corey says she and her team never forget that they're working on victims who have yet to be seen by their loved ones. >> our goal is to place our incisions such that the family will be able to have their normal funeral arrangements, that they would if the person had not undergone an autopsy. >> something in this case may pose problems for the funeral director, those nasty burns investigators found on ashley's back. >> i saw evidence that she had been sitting on a seat warmer in a car. >> the heat accelerated body decomposition, but dr. corey says it won't affect the autopsy. before long, dr. corey is able to reconstruct more of the murder scene, based on her findings.

>> so she was pretty much looking toward the gun at the time the gun was fired. she could be turned like this at him, or her, when they point the gun at her and fired. >> then she begins her search to retrieve the bullets, perhaps the most important evidence for investigators. >> i think we're going to recover the bullet from right under there, the bullet that's associated with the gunshot wound to the face. coming up, inside another autopsy, ashley's boyfriend shot in the driver's seat. did he see it coming? >> he's got a couple little scratches on the side of his face. >> signs of a struggle? important clues. evidence, perhaps, to track down a killer. i don't use super poligrip for hold, because my dentures fit well. before those little pieces would get in between my dentures and my gum and it was uncomfortable. even well fitting dentures let in food particles. just a few dabs of super poligrip free is clinically proven to seal out more food particles

so you're more comfortable and confident while you eat. so it's not about keeping my dentures in, it's about keeping the food particles out. try super poligrip free. it's the brand more doctorsose recommend for minor arthritis pain. plus, just two aleve can last all day. you'd need 6 tylenol arthritis to do that. aleve. all day strong. trust number one doctor recommended dulcolax constipated? use dulcolax tablets for gentle overnight relief suppositories for relief in minutes and stool softeners for comfortable relief of hard stools. dulcolax, designed for dependable relief at ally bank no branches equals great rates. it's a fact. kind of like ordering wine

more than 7 million people will likely need help. in mexico, they believe they're closing in on el chapo guzman, who isally alleged to have injured his leg and face. the city of louisville has been shaken up by a brutal double homicide. the case began when two young people were found dead in a car in an alley. now, the bodies of the gunshot victims, ashley yennous and anthony housy, are being evaluated by medical examiner tracy corey. she is looking for any evidence

that can help investigators crack the case. dr. corey is at a crucial stage in ashley's autopsy. she's searching for the bullets that killed the 18-year-old girl. >> it's going through here. this one in here passing through -- i think it's impacting the inner table of the skull here, and it just doesn't have enough energy. i think we're going to -- right, we're going to get the bullet -- right, right under there. >> after several minutes of probing, there is an unmistakable sound, metal on metal. >> there's that one. >> one down. >> one down. >> continuing her search, dr. corey finds the second bullet -- >> there it is. >> just lying free. >> -- and extracts it. >> inside the scalp. numero dos. >> she's pleased at the condition of this bullet, like the one already recovered, could help police track down the murder weapon. >> it's relatively well preserved and it's got good markings on the outside of it. >> even though it's her job to help the investigation now, dr. corey, unlike her fictional counterparts on "csi," will not

take sides in any future trial. >> we're there to solve the puzzle. we're there to figure out what happened. we're not there to figure out who did it or whether or not a person's guilty or innocent. i testify when subpoenaed by either side, and i testify basically as to what the victim told me. >> at the end of the autopsy, dr. corey closes her eyes in deep concentration and then dictates her findings, in rapid-fire pathology-speak. >> the scalp revealed soft tissue hemorrhage in association with the two gunshot wounds involving the left aspect -- >> at one point dr. corey stops and walks across the room and gazes intently at an anatomy chart on the wall to refresh her memory. >> good forensic pathology labs has a lot of charts around because we can't keep it all in our brains, you know? it seemed to me as i went through medical school, i got to a point, whenever i put a new

fact in, something fell out the other side. so a good forensic pathologist doesn't know it all. they know where to find it all. >> on dr. corey's way back to the autopsy table, something unusual catches her eye. could it be an important clue to the crime? >> i've never seen a shirt like that. >> with eye-popping blood and body parts everywhere, this forensic pathologist, this trained observer, is stopped in her tracks by, of all things, anthony's shirt. quickly, though, she's back to the job at hand. >> opinion, death in this 18-year-old woman is attributed to penetrating gunshot wounds of the head. the code for that is -- >> we know it as murder, but in the autopsy room, the manner of death gets a code name. >> the code for that is e-965.4a9g. end of dictation on 0799. thank you.

we are there to serve the public. people a lot of times say, oh, you just work with dead people. well, there's nothing that could be farther from the truth. >> and in the pursuit of the truth, the medical examiner's part of this double-homicide investigation is only half-done. it will continue with the autopsy of ashley's boyfriend. >> have we seen his wound yet? >> no. he's got a hole in his calf. >> where is that? oh. this is tracy dictating 07100, 07100, body identified as anthony housy. >> anthony housy is the 20-year-old who was discovered dead in the driver's seat the day before. >> the body is received with the hands in paper bags. the paper bags are removed from the hands. >> remember, police bagged his hands to preserve any evidence. they're looking for dna and possible gunshot residue under his fingernails. gunshot residue might tell them

if anthony himself recently fired a gun. dna might indicate a struggle, and help lead police to a suspect. >> back to exterior. jaw displays rigor mortis. take a picture of the little scratches on his face. he's got a couple little scratches on the side of his face. i don't know how long those might have been there. they're oriented going down and, i mean, they would be consistent with somebody's fingernails. can i say that's what they're due to? no. but they're certainly consistent with that. >> that's a definite maybe. but dr. corey can say with certainty that anthony has a single gunshot to the back of his head, confirming what the police suspected. >> scalp demonstrates a one-quarter-inch roughly circular gunshot wound of entrance on the right side, which would, again, be consistent with the shooter being in the back seat, kind of

in the middle. is that what it looks likes on the -- >> uh-huh. >> but finding that bullet embedded in his head is proving harder than anticipated. it's such an important element of the police case, however, that she must keep looking. >> still not there, huh? i don't find it. >> it's got to be here. >> finally, she finds it. >> there it is. this bullet is relatively pristine, especially where the lands and grooves are. >> which means the bullet might turn out to be a big help to investigators. >> if the investigator then recovers a gun, the investigator can take that gun and that bullet and see whether or not those two bullets match. on the cause-of-death statement, put single gunshot wound of the head. under the manner of death in this case, check the box for homicide. >> dr. corey has accomplished what she'd set out to do,

perform autopsies that uncovered evidence that could aid the investigation, autopsies that were dignified and efficient, allowing ashley's and anthony's bodies to be returned quickly to their families. coming up, in the days to come, ashley's mother, angela, will do whatever she can to aid the investigation. >> from what i hear, ashley was running, because this, whoever, was looking for her, threatening to kill her. that's what i hear. i asked my dentist if an electric toothbrush

was going to clean better than a manual? he said sure. but don't get just any one. get one inspired by dentists. with a round brush head. go pro with oral-b. oral-b's rounded brush head cups your teeth to break up plaque and rotates to sweep it away. and oral-b delivers a clinically proven superior clean versus sonicare diamondclean. my mouth feels super clean. oral-b know you're getting a superior clean. i'm never going back to a manual brush.

cook, because it's procedure oriented and we get to use knives, i think. >> straight into the water at 17. >> actually, tracy corey, kentucky's chief medical examiner, is more comfortable in the saddle than in the kitchen. she says it's been that way for a long time. how long? >> oh, gosh, for as long as i can remember, every little girl wants to go ride a pony. i was just lucky enough to live in the horse capital of the world and was lucky enough to have parents who helped me be able to ride as a child. >> but her youthful goal of riding competitively was sidetracked by medical school and then children. >> and all of a sudden, i turned around at 43 and said if i'm ever going to ride, i better do it now. >> her husband and fellow groom who helped her prepare for competitions like this one in florida last winter, was involved in that decision -- sort of. >> i said, so, you know, i'm

thinking about -- i'd like to maybe get a horse again. so he said, so, okay. so we'll need to talk about that. and then i came home and i said, "i bought a horse," and he said, "i thought we going to talk about it." i said, "we did." >> her idea of talking about it and mine are two different things. >> how she approaches this hobby is exactly how dr. corey lives her life, with compassion and drive. the compassion is evident in her choice of horses to ride. instead of fancy show horses, tracy takes broken-down thoroughbreds and retrains them for a new career. her drive is clear in how she's attacked her sport, successfully, at full throttle. >> i'm very obsessive/compulsive. you know, i'm very attentive to detail. i'm very goal oriented. and so for me, it's a great outlet. >> so it's no surprise that

she's quickly become a top equestrienne. it's a demanding sport and not exactly what most people would consider relaxing. >> the relaxation is in the focus away from work. >> tracy corey. >> in the case of the double homicide, dr. corey has done her part. now the investigators have to follow up. lead detective chris middleton, who started gathering evidence on the case in the alley and then the garage, has been working just as hard on his end of the investigation. here, he is running down a lead in new albany, indiana, just across the river from louisville. >> this apartment behind me is of interest to us due to the fact our victim, anthony housy, was living here on january the 14th. >> that was three weeks before the fatal shooting in the alley. a man came to anthony's apartment complex looking for

anthony's girlfriend, ashley yennous. >> anthony told him, she's not here. at that time, the door's immediately kicked in. >> the intruder was brandishing a gun. >> there was actually a shot fired. our male victim was able to break free, and ran down the steps and to the front yard that you see behind me. when he came out, he was only in his underwear and did have a lot of blood visible on him. >> now detective middleton is searching for a possible connection between the two shootings. and in looking for the link, he's been working closely with the families of anthony and ashley. >> we're receiving great cooperation from the family and friends. >> and he's also getting cooperation from this man, christopher 2x, a local community leader who crusades against violence. 2x helped persuade the families to meet with police. >> they were very kind of reluctant to open up to them and i told them it's in their best interest if they want to solve

this complex puzzle. >> the community leader also has found ways to keep the case, which has become big news in louisville, front and center. he's organized a news conference with ashley's mother, angela thompson. >> why? just why? why would you want to do that? why would you take my baby from me? >> angela says she knows who would want to kill ashley. she suspects a former boyfriend and possibly the same man who, according to detective middleton, had wounded anthony at his apartment. >> from what i hear, ashley was running, because this -- whoever was looking for her, threatening to kill her. that's what i hear. >> so why do we think that she was running? why was she being threatened, i guess is the other question? >> because she didn't want to be with that man. and i guess he wanted to be with

her and she didn't feel the same that he felt, and he told her he was going to kill her, and that's what he did. >> that's what you think? >> that's what -- yeah. that's what i think he did. >> but whoever killed her daughter has left angela thompson with a gaping hole in her world. >> she was my best friend. my best friend. >> the other victim, 20-year-old anthony housy, also is missed terribly by his relatives. who asked christopher 2x to speak for them. >> grew up loving sports, his interest was basketball and football. the family is so heartbroken by what happened. >> ashley loved "spongebob squarepants." that's why we got spongebob as

our symbol of the hope that ashley gives. >> on tuesday night, christopher 2x continued to keep the case in the public eye, organizing a vigil for ashley and anthony, in the same alley where their bodies were found. solving these crimes. christopher truex puts us in a positive light to where people want to give us information. some of them we already know. >> are police getting any closer? coming up -- >> you're thinking -- man,

. a dramatic week in the life of a double homicide case. from discovery to autopsy. to investigation, to finale. >> tonight police say two suspects are behind bars for the killings of a young couple.

>> a week after detectives found the young couple shot to death in a car, louisville police made a major announcement. >> both turned themselves in last night. >> they had in custody two teens, a 17-year-old and a 19-year-old, responsible, they say, for the cold-blooded murders. after working nonstop to find the suspected killers, lee detective chris middleton says he felt some relief. >> i'm happy there was an arrest made, it was nice to call the families. >> early as the doctor's examinations confirm that the case was indeed a double homicide, the police were out pursuing leads. one tip in particular helped break the case. in the hours before the murder, the two victims had been seen with two young men hanging out across the river from louisville, in indiana. on thursday, those two young men, aware that police wanted to talk to them, came down to

police headquarters. when detective middleton questioned them individually, each claimed he hadn't seen the murder victims for months. >> you're thinking, man, you're lying. and there's no reason for to you lie if you're innocent. >> then police showed them a surveillance tape from this convenience store, that showed the four of them together, the video was shot just hours before the shootings. >> those cameras are not capable of lying. they show what they see and tell what they see. middleton says seeing the videotape broke the suspects down. but each accused the other of being the shooter. he says the motive for killing anthony housy was robbery. and that ashley ynez was shot just because she was a witness. police say the community as a whole did its part to help solve the crime. >> they were very helpful. they hear things, we receive these tips and follow up on

them. >> the previous shooting at anthony housy's apartment, it turned out, was unrelated to the two arrests. but at the time, middleton believed it was a lead worth pursuing for more than just the victims. >> i've got a duty to their parents, brothers and sisters and children. to find the person responsible for that death. so far, police have not found a gun. so the pristine bullets dr. cory carefully extracted in her forensic examinations have not been matched to a weapon yet. how did dr. cory feel when arrests were made in two of her autopsy cases? >> i just heard it on the news and i'm happy for the families that that will help them get some closure. but as a forensic pathologist, my role does not involve being emotionally invested on whether or not someone is charged with a crime, whether or not someone is guilty or innocent. >> that would surprise fans of

some tv shows, in which medical examiners often seem like extended arms of the law. dr. cory says she doesn't watch those shows. though she once tuned into an episode of "crossing jordan." whose main character is a dynamic female medical examiner. sound familiar? not to dr. cory. when she saw the fictional medical examiner leaping over a fence, she said she just shook her head. >> she was breaking into an impound lot to reexamine a car at midnight. you know, i don't do that. i stay at home. i think that that might get you in trouble. you might lose your license and your job. >> to do her job properly, dr. cory has found she must separate herself from the devastation of the deaths as much as she can. >> i try not to think about the actual tragedy of the event. of course as a human you're always going to eventually think of that. >> people may shudder at the thought that she works on cops corpses, but she said if there's

anything her job has taught her, it's that dead people aren't the scary ones. >> in our facility we have a dedicated elevator that the deceased are transported on. and that elevator is used by some police officers. and there's many police officers who won't get on the elevator if there's a deceased person on the elevator. and to me, that's a little, little bit backwards. the dead people, they can't hurt you. the living people are the ones who pose the threat. >> when she does reflect on the senseless death she sees all the time, like the double homicides of an 18 and 20-year-old, she says she gains important perspective on life. >> it makes me very aware of how precious every single day is how precious every single hour on this planet is. and that's why i fill them all up as much as i can.

these doctors communicate with the dead. >> she was looking toward the gun. >> medical examiners. their job is to uncover clues from the bodies that speak to them. clues that can solve crimes. >> i think we're going to recover the bullet from right under there. >> this time, a case that breaks the mold. >> i've not seen one like it. >> a young man is missing. his parents are frantic. >> we looked until the police said, you've got to stop. >> it's a
