i said, well, you know, i really got a pertinent matter to discuss with you, if there is anyway you could possibly have them call you back. >> what was the pertinent matter? >> it was letting her know that i discovered she had been having an affair the entire time. >> was that who was calling her the person you -- >> i kind of got that feeling that that's who was calling her. >> in fact, it was ed rollerson. >> i called her, she answered and immediately i could hear her and chris kind of arguing. so she's telling him to get out and he's constantly saying, i need to talk to you, i need to talk to you, i just need two minutes. >> ed said he we heard something else come out of chris'mouth. >> he talked to her, it's a matter of life and death. she asked him, what do you mean a matter of life and death?

>> in his interview, chris admitted he and heather continued arguing when she hung up with ed. he insisted she was alive when he went home and he said, she sent that disturbing good-bye e-mail only after he left. >> i'm freaking out, you know, because i still, i don't know that this isn't a game. >> detectives had been analyze tack strange e-mail and they asked forensic experts to comb through chris'computers seized at his apartment. a theory began to emerge. investigators now believed chris had written the e-mail, himself. >> did you suspect that chris was posing as heather, sending that e-mail? >> yes, i did. because chris was an expert when it came to computers. >> and what's more, they suspected it was chris who actually sent those sexy texts to ed, not heather. he believed he had stolen her phone and was pretending to be

her. >> that is really weird. >> oh, yeah. >> you are getting sexting from her husband? >> yeah, her husband. kind of -- i need to put that oust my mind. >> chris'plan, detectives the host, was to throw them off the trail, to make it look like heather ran off and was having an affair. but they didn't believe a word of his story or that his concern for heather was genuine. >> the reason you were freak out is because she was dead. your actions after that make no sense. everything else after that was an alibi. >> okay so what did i do with her? >> that's what we're asking, chris. >> chris was sticking to his story, but the biggest break in the case was about to happen. what chris didn't know is that while detectives were turning up the heat inside the interrogation room, outside they sent some cadaver dogs over to the mall to sniff around his car and now the team at the mall wanted to speak with detectives immediately. >> they said the dogs just hammered his car. they said they're all over it. >> they found the scent of human remains. >> i don't know why the cadaver dogs hit on my car. >> i do. they don't just hit on

anybody's cars, they don't hit on cars out of the blue. >> what is it they are trained to detect? >> deed rapt decompensation. >> wallace had chris against the ropes and he was finally going to get some answers, not just about what happened, but why. the startling revelation. heather's radical makeover of her body and life had put her life in imminent danger. >> coming up, a whole new story from chris. was this all some awful accident? or could it be murder with a mind blowing motive? >> do you think that heather would still be alive if she hadn't gone through this transformation? >> yes. it works naturally with the water in your body to unblock your gut. ...free your gut. and your mood will follow. it's started. somewhere between a cuddle and a struggle, it's...the side hug.

blue diamond almonds. crave victoriously. from 10:00 a.m. there i said, this is where she is. that's where she is. >> detectives raced to the area and followed chris'directions down a path into the woods that led to a clearing. >> once we could see an area on the ground where a fire, what had looked like a fire had taken place, once we got closer to that, we could tell there was still a human form there. >> seven days after she disappeared, detectives had found heather. her body had been badly burned. >> we were broken hearted. we had lost her and she was a big beautiful part of our group. >> chris jones was arrested and charged with first degree murder. now the women who had helped heather find the courage to leave her husband supported

their friend in death. staring down chris jones at every court appearance. >> there's a monster inside that hurt our friend and that we want justice. >> prosecutors rejected chris'story that heather had died from an accidental fall. they believed he argued with her at the house that night, strangled her and then burned her body in the woods. but the question remains, why? heather's friends provided a surprising answer. they were convinced heather's dramatic weight loss got her killed. >> do you think that heather would still be alive if she hadn't gone through this transformation and bettered herself? >> yes. >> heather's friends and family said over the course of their relationship, chris used heather's weight as a tool to control her. >> at the beginning, he wanted her to be bigger, he felt that would be more attractive to him. then as she got bigger, then he

would say to her, nobody else would want her because she was so obese. >> when heather finally created her transformation, she confided chris didn't have the reaction. she said, chris wants me to put the weight back. he doesn't want you to go out there. he doesn't want anyone else looking at you. >> he said chris brought fatty foods to her, hoping she would pack the pounds back on. >> he would go up to the school with food. and she would not want any part of it. >> with the sole purpose of trying to get her to gain wieth? >> is what she had told me, yes. >> friends said the nud and improved heather never took the baits. after years of increasingly unhappiness, heather found out something for her was the last straw. >> she discovered that chris was having an affair with another woman.

>> that's when she finally spread her wings and found the courage to leave her marriage and she never looked back. >> you could see that her spirit was lighting up in her sense of security and what all the future was going to hold for her. >> in february of 2015, chris jones went on trial. heather's friends took the stand to help prove the prosecution's theory. when chris realized he had lost control of heather, he took control in another way. >> find that man guilty of first degree murder. >> prosecutors laid out their case to the jury. >> it wasn't an accident. >> assistant district attorney daniel mccollum. >> she didn't fall down. there was a struggle. he did strangle her either with his hands or however he did it. he was up close and personal to her and he was there watching that breath go out of her. >> but the defense stuck to the

story chris told on tape. >> that heather fell and died after they struggled over a cell phone. >> he never admits to killing her. >> the judge asked chris if he wanted to tell his story to the jury? >> i think i will choose to not testify. >> it was now up to the jury to decide his fate. >> finally, after deliberating for a day. >> we, the jury, find the defendant guilty of murder first degree. we the jury find the defendant guilty to abuse of a corps. >> tears flowed for heather, a woman who worked so hard to shape her own life, free of chris jones, will now likely spend the rest of his life behind bars. he told "dateline" from a phone call from jail, he never tried to control heather.

>> that he is absolutely innocent of mertz of any type and his statements to police were coerced. the detectives said chris jones talked to them voluntarily and could have ended the interview at any time. as for cousin diane, she has obtained legal custody of heather and chris'two children. heather's gym friends, they find comfort in knowing that before her death, heather achieved that remarkable journey. becoming the person she was always meant to be. >> she got to experience back before she left this earth. she got to experience as beautiful as she was inside and out. >> that dance class where heather spread her wings still keeps a place for her.
