late in north western new york. the farmlands told by amish and that families are encased in snow and ice for months at a time. but in this place of frozen stillness. the hottest of passions, boiling jealousy came to call one day. and tiny clymer, southwest of the county, still shaking off the shock of it all. joe gerace was the sheriff of chautauqua county. >> in my 35 years in law enforcement can i remember a murder in this county? never. >> it began quite simply. the new school superintendent in town went missing one weekend just a few weeks into the school year. september 2012. keith reed, 51 years old, was a longtime educator who had landed in the sweet spot of his professional career. the up until then school principal had applied for the top administrative job in the clymer district with his brother kevin urging him on. >> he says, it's this little school out in chautauqua county

called clymer. i don't know whether i should apply there. i said, you know, apply. >> you might think a close knit community like clymer would be standoffish to newcomers. but parents and students quickly embraced a hands on mr. reed. his eldest daughter katelynn. >> he greeted the kids in the morning, coming off the bus. he talked to them during the day. he was in the hallways. he really loved teaching and working with kids and he was wonderful at it. >> the new superintendent had three grown daughters and a painful divorce behind it. but he never let lives difficulties distract from his primary role, dad. megan is the middle child. >> he loved to have fun. he would always dance crazy with us like pick us up in the air and slide as between his legs and throw us up. >> and the old family snapshots, hiking in hawaii, disney world, all the christmases, seemed to show a dad over the moon with his three girls.

katelynn was a star volleyball player and all american. and knew without a doubt when her father is in the stands on game days. >> you could hear him? >> i could. everyone could. [laughter] >> her dad was in a long term relationship with a single mom named kimberly roush. >> he had three daughters and i had two boys. a lot of our time was spent being involved in their sporting events. >> they'd been on again off again for years, but no sooner had they decided to take one of their periodic romantic timeouts from one another, then they'd rubber band but back together. >> a song would come on, he pulled the car over, take me out of the car, and dance along the side of the road. [laughs] being with him was amazing. >> and now that his girls were grown, keith reed was at long last finding his special place, getting comfortable. he bought a big house in town. a sign the superintendent wasn't just using clymer as a career steppingstone. >> he found where he wanted to

be, finally after years and years of looking. they'd have to pry him out with a bar. >> but on saturday morning, september 22nd, 2012, one clymer's school principal and bailey drove by his friend and colleagues house, he was surprised to see both of keith's vehicles still in the driveway. the superintendent was meant to be across the state at an educators conference. >> i made a mental note i was going to be coming back by there, both vehicles there all stop and see what's going on. >> when all looked the same on his return trip, the principal pulled into the drive. >> i actually went into the door of the house and yelled his name, and of course there is no answer. >> someone else who started to wonder what was up that saturday was katelynn. the two spoke by phone every day. >> he didn't answer my phone call, and that saturday. i thought that was a little strange, but i was busy, so i kind of forgot. >> by sunday, his little daughter meghan had become very concerned. she hadn't heard from him either.

worrying. >> i was, like ok, answer your phone, it's time to answer your phone now. you know, i was confused because he always just answers the first time we call. >> that sunday night, her uncle kevin, a former fbi agent of 20 years, was being called to the house in clymer via school official. >> they said, we can't find your brother. i said what do you mean, you can't find my brother? he was supposed to be at a conference in albany, didn't check in at the hotel. both cars still at the house. i said, okay, we are coming. >> kevin is hoping for a simple explanation that they'd come upon his brother on the property hurt and unable to get up. >> my hope was he had gone out back, there's a huge tract of land behind his house. he was laying out there, and couldn't get up. >> when he walked into the house, the former fbi man didn't like what he saw. >> i started looking around, and here is $600 in his wallet, his suitcase is partially packed. i came back downstairs, said everybody out. everybody out. when he talked about? i said go in the garage. this is not going to end well.

this is a crime scene. >> principal ed bailey was taken back by kevin's comment. >> i understand we have an issue here that keith is not where we thought he should be. but what do you mean it's not going to end well? >> the principal had called the sheriff's office to report keith missing. deputies had responded to the scene. >> nothing added up. he had a bag packed, it looked like he was preparing for his trip. but nothing else that was out of place. >> deputies broke out flashlights and searched the house, the grounds, but no luck. keith reed was flat out gone. and it's really a mystery to them, when they leave the house. >> correct. >> sunday night ended in drenching rain. darker than usual around the house. they had't yet figured out why the exterior lights by the garage weren't working. they hadn't talked to the neighbors about some loud voices they heard. where was the school superintendent, mr. reed? >> coming up -- as the search

continues, police make a startling discovery. >> so your missing person case has suddenly become a homicide. >> correct. and it was like, wow. >> when dateline continues. ♪ control of my crohn's means everything to me. ♪ ♪ control is everything to me. ♪ feel significant symptom relief at 4 weeks with skyrizi, including less abdominal pain and fewer bowel movements. skyrizi is the first il-23 inhibitor that can deliver remission and visibly improve damage of the intestinal lining. and the majority of people experienced long-lasting remission at one year. serious allergic reactions and an increased risk of infections or a lower ability to fight them may occur. tell your doctor if you have an infection or symptoms, had a vaccine or plan to. liver problems may occur in crohn's disease. ♪ now's the time to ask your gastroenterologist how you can take control of your crohn's with skyrizi.

first day of school in september, 2012. in three weeks time, the high- profile educator would be reported to the sheriff's office as a missing person. >> the school superintendent that everybody loved. the kids loved him. he was there every morning greeting them as they get off the bus. >> keith's last known whereabouts was dinner with a friend on friday night. a security camera caught him leaving the restaurant around 8:30 pm. the next day, he was a no-show at a big state educators conference across the state. his brother kevin reed, a former fbi agent, had a bad feeling about things when he arrived at his brothers house sunday night. >> i went right into fbi mode. i didn't have time to get emotional. >> his brother, grounded, stable, reliable, was no one's candidate to just one day go missing. especially not then. just a few weeks before, he had had the moment every dad lives for. walking his eldest daughter, katelynn, down the aisle. >> it was one of the most momentous days of his life. i've never seen him that happy.

>> at the reception, he even busted out his signature dance moves. >> he lived it up on the dance floor. >> he was a very happy guy? >> yeah, he was. >> but now, as dawn broke a month later, monday morning, september 24th, keith reed had vanished. the sheriff's people were dispatched again to do a daylight search of the grounds. it wasn't long before a canine handler reported back. keith reed, his body, had been found. >> immediately the dog found the body in the shrubs. >> keith's girlfriend kimberly was driving to a new job that morning when she got the news. she couldn't believe what she was hearing. >> he's dead. they found him. i just started crying and i said, no, that's not possible. >> but tucked into the hedge row about 50 feet from his driveway lay keith's body. he had been shot three times,

twice in the back, once in the chest. all at close range. >> it was like, wow. how could this happen? who could've done this? why would they do it? >> those same questions were soon roaring through the halls at keith school. principal ed bailey had gotten the news from the sheriff's office. >> i just about dropped the phone. i just couldn't believe it. >> we're talking about keith reed? >> yeah, my friend. >> along with a shock in the community, came an unnerving question. given the national climate of school related shootings, could keith reed have been targeted because of his work leading the district? an angry student, a disgruntled parent. was any of that even remotely possible? >> i'm thinking and going back through. did he have any enemies. who possibly could have been upset enough crazy enough to do something like this? you know? >> did you come out with any possibilities? >> there was one incident that i know of that the family was very upset with him. >> school related beef of some kind? >> school related. but, you know, nothing out of the ordinary.

nothing that should have ever rose to this level. >> neighboring districts were understandably on edge, too. were they next? >> my phone blew up from other schools. are we in danger? is this beginning of something bigger? there was a lot of people worried. >> and concern only heightened, the sheriff said, when word spread that an unknown man had stopped by keith's school around noon that friday, asking to see mr. reed. he >> had told him that he was applying for a job as a substitute teacher. that he came in from connecticut looking from work. >> the man, seen here, was captured on school surveillance cameras. was this visitor a piece of the puzzle? detectives didn't know. but given the potential nightmare of schools and children in jeopardy, it was more important than ever for the sheriff to have all hands on deck at the crime scene. david foley was county district attorney at the time. and he was there when a door to door canvas turned up a critical clue for the timeline. >> a neighbor couple had heard

gunshots, three gunshots, friday evening. somewhere around 9 pm. >> on the property itself though, detectives found themselves frustratingly short of clues. but they did recover in the grass a soggy piece of paper that looks like a receipt. it would be work for the lab to figure out. and around the garage, investigators took note of something perplexing. three exterior lights, the bulbs were missing. >> why are the bulbs gone? this is odd. this was really odd. >> so, somebody had done some planning? >> rang to the doorbell, can't see who's out there, flips the lights on. nothing happens. opens the door. there is his assailant. >> so, the shooting of the superintendent for a grievance unknown became one theory to pursue. but detectives were about to hear a story that would make them look at the crime scene in a completely different way. something more traditional. was it possible that keith reed was the victim of a bad romance? as it happened, a candidate for a suspect. someone on again off again was about to pull into the drive.

his house. he'd been shot three times. keith's brother kevin, a law enforcement veteran, had caravaned to the house monday morning with his 80-year-old parents, expecting to search for a missing person. the sherrif broke the news. >> now i've got my mother wanting to go and cover him up with a blanket because he's cold. try that sometime. it's a crime scene, mom. you can't go up there. it's tough. >> as the reed family struggled to make sense of the horror, investigators would put the question to keith's daughters. did they know of anyone who had a reason to hurt their dad? >> we could not think of anyone to tell them. no one. >> everyone was just... no. >> but a name had occurred to their uncle kevin. of the leads to sort through, he suggested investigators looked at keith's on again off again girlfriend of many years, kimberly roush. >> i said, first thing you need to do is talk to kimberley. >> where did that come from in

you? >> experience, and knowing the relationship. >> the investigators learned from kevin and others that the superintendent's relationship with kimberly at at times been rocky. they had been engaged to be married, but keith recently called off the wedding. >> but the time summer was over, like no, we're not doing this. >> was this what's the crime scene was all about? a deadly confrontation between a man and his lover, upset over a canceled wedding? kimberly, who lived almost two hours away raced to the house. >> i said kevin, what happened? i said, did he have a heart attack or something? he said no, somebody shot him. and i just started sobbing, and i started to go down to my knees in the road. >> investigator randy boland was assigned to talk to her. >> she is crying. very, very emotional. so, i immediately go and speak to her, but i give her some

moments. >> but in the investigators eyes, kimberly quickly went from grieving girlfriend to potential suspect. he asked for her phone. >> i said, okay, is there a reason why? i was kind of shocked. >> it turns out that keith had asked kimberly to join him at the educators conference that weekend. she said they'd never finalized the plan, but she had been mad at him for not returning her calls. >> she gets very upset in her text messages back. like i can't believe you are not talking to me. half violent. like, why are you not calling me? >> flaming stuff, right? >> yes. >> and something else, in keith's bedroom upstairs, crime scene analysts noticed this picture frame. it was toppled over and taken apart on the bookcase. whatever picture had been and it was gone. you could put a sort together without a pretty easy? >> the pieces of the puzzle were just starting to come together. >> investigator boland brought kimberly in for a formal taped

interview. she was read her rights. >> i mean, i'm still in shock. i barely have my head around that he was killed and now i feel i'm going right from that into, are you the one that killed him? >> i just found out he was dead this morning, and then i show up and i found out he was shot. and now, i feel like i'm a suspect. >> kimberly told investigator boland she'd been three hours away at her parents'house at the time they believe keith was shot. she admitted while she did get angry with him, she would never hurt him. >> never in a million years, no matter what he said or did, did i ever consider or conceive the thought of harming him, or hurting him, or living without him. >> i remember feeling absolutely terrified, and i thought i have two little boys that home. i need to get home. they don't even know he's gone.

>> in some of your messages, you've displayed that he has -- >> people say things in anger. >> anger, you know what i mean? >> i've been angry. you've been angry. anybody would be in certain situations. that doesn't make them a killer. >> but had there been a trigger leading up to friday night? the investigators saw in kimberly's text messages that she was intent on getting back from read a high school diploma. something she thought might be at his house. >> i used the f-word and said i'm sure you are obviously there with another woman, and i don't even care. i need my [bleep]. i told him, why don't you just pick your [bleep] phone up. you think i'm going to show up and shoot him over my missing diploma i can't find? i would go there, look through the bins, find it, take, it and leave. >> but what about that picture frame? detectives thought it might have been toppled over during a fight. >> no, we've never broken pictures of each other.

so i really had no idea what they were talking about. >> investigator boland confronted kimberly with a working theory. thinking keith was away, she stormed over to his house with a male friend to get her diploma back. only keith was still home, an unhappy surprise. >> there is an issue here where there's two males going at it. did you see something you didn't want to see? seriously? >> i wasn't there. >> not at all? >> not at all. >> they were thinking i was guilty of this. and i loved him so much, i could never have even thought of doing anything like that. >> the nearly three hour long interview was over. kimberly was still in the crosshairs, and the thought was terrifying to her. >> am i going to go to jail for something i didn't do? >> but investigator boland had his doubts she had anything to do with keith reed's death. >> she didn't leave my suspect list, but at the same time, she seemed genuine that she would

never do something like this. >> meanwhile, there had been a very puzzling development in the investigation. the sunday night the superintendent was reported missing, the cops had asked the phone company to ping keith reed's cell phone to ask it the technological question, where are you? the phone answered back electronically, i am in harrisburg, pennsylvania. >> this man is dead and hedges by his, house and his phone is in harrisburg, pa? hours away? >> hours away. >> a school superintendent dead at his home. his phone more than 200 miles away. what was going on? >> things get way more complicated when a second woman makes a phone call to the sheriff. >> coming up -- >> i don't know. >> just relax. >> she was very, very upset. >> when "dateline" continues.

i didn't know what to do or where to go next. and he was great. he was really encouraging. >> it was sometime in the summer of 2010, she told the detectives, that she met her online match for their one and only date. >> he took me to dinner and we had a night together. >> it was a little more than a one night stand. mary says she decided to try to make things work with her husband. keith reconciled with his girlfriend. >> we both just kind of said good luck to each other. >> so, it was like a handshake and goodbye.? >> pretty much, yeah. >> but a couple of years later, mary says, her marriage was once again coming undone. in the spring of 2012, she tried to friend keith on facebook. he didn't accept the requests. but the superintendent did write her a message. >> he sent me a message back asking me how i was. and i told him that i was unhappy. and things were not going to
