but you d be surprised what people will say. reporter: the year after roger s trial, his brother rodney was convicted of murder and sentenced to life. roger still says rodney acted alone. one of the things that s hard to wrap your head around is that rodney had this love for you. he looked up to you. and for rodney to turn on you and say that my brother asked me to kill his wife and i did it out of love for him, why in the world would he make that up? maybe to save his own life. i heard that they were trying to give him the death penalty. and the only thing that he could have done to even save his own life was to say something like that. maybe get a little bit of sympathy as far as why. reporter: but this is a man who loved you. well, if he loved me, he wouldn t have killed my wife. reporter: you do seem though like you re playing the part of victim a little bit by saying, this person made this up. this person made this up. poor me. all these people are lying.
lynn s. and then i remember lynn telling me that roger had told her that rodney was going around calling her names, you know. calling her vulgar names that she s the reason that he got kicked out, that she s the reason that all these things happened and stuff. reporter: did you see that as a motive? i never thought that that in itself would have been a motive to kill her or that he would have been that angry just because of that to kill her. reporter: why in the world would rodney want lynn dead? i don t think rodney wanted lynn dead. here was a person that was willing to help us in the investigation. and he was very cooperative initially and throughout. reporter: the search for suspects continued. lynn s neighborhood turned up nothing. same with fort bliss. lynn had no enemies there. you couldn t imagine that it could ve happened. it seemed unreal.
move, she wants to take me away from my friends here, you. i love you. she wants to separate us. reporter: rodney told police his brother had no shortage of reasons for wanting lynn dead. prosecutor john gibson. roger wanted the life insurance policy. he wanted custody of his young son. he knew that if his affair with april became apparent, that he d face consequences in the military to include prosecution and military jail. he didn t want to move to follow lynn in her career to minnesota. he wanted to stay and he wanted to party back here in el paso. reporter: and rodney said roger didn t just talk about why he wanted his wife killed. he says roger talked about how and when. he describes roger preparing the weapon, preparing extra clothes for rodney to change. reporter: rodney said the plan was for roger to call him that morning to say his battery was dead. was that the signal?
you needed to throw out. it was a wide investigation at the time. yes. reporter: you had a killer on the loose. yes. and the neighbors were very scared. who s out there? who did this? reporter: in those first few hours, the leads would pour in, and police had to move fast. lynn reister had inspired loyalty in her life. now in death, the detectives could not let her down. on base, a giant military family is hit hard by murder, but in lynn s own family, had there been signs of trouble? coming up an army commander being murdered was unheard of. rodney was going around calling her names, vulgar names. he had a little bit of animosity towards lynn. when dateline continues. ws , you know how i feel. breeze driftin on by. if you ve been playing down your copd,. it s a new dawn, it s a new day,. .it s time to make a stand.
get home. but her old life was about to change. about four months after she got back, roger convinced lynn to let his 24-year-old brother rodney come live with them. rodney had gotten into some trouble while his brother was serving his country. maybe roger and lynn could set him straight. he was on probation in florida, and for him to be able to leave the state, she had to write this letter, you know, saying how she would take on that responsibility. roger asked her to do that, and so she did. reporter: right about the same time, lynn found out she was pregnant again. the tug of motherhood was getting stronger, so this globetrotting army captain made a decision. she put in for a transfer to teach rotc in minnesota. good for her career. good for her family. and no travel. was she doing it at all to be with triston more? was that part of it? yeah. that would be part of it. yes. she wanted to it s more relaxing. she was going to be a teacher. it was something that she was
