it almost made me sick. i was on the floor. and then i kind of got myself together and i said, we have to go over there. i have to go over there. >> in the muscular military world, she was a commander who cared. >> i was like, what are you doing? and she says, i'm writing birthday cards to all my soldiers. >> her husband a charming sergeant and devoted dad. >> he was just as loving and doting as lynn was. >> no one could believe it when this decorated officer was found dead in her own home. >> an army commander being murdered was unheard of. >> the first suspect, as usual, the husband. but this one had a rock-solid alibi. >> it would have been very difficult for him to have committed this murder. >> did this soldier have enemies off the battlefield? her brother-in-law had a grudge.

calling her names, vulgar names. >> her husband had a girlfriend. >> roger was sitting with a young lady. and they were cuddled up. >> we found out that she was pregnant. >> who killed the commander? in a place where loyalty is prized above all, one clue -- >> that palm print was a key part of the case. >> -- would reveal a breathtaking betrayal. >> i don't even have the words. what a monster. >> i'm lester holt, and this is "dateline." here's andrea canning with "deadly devotion." >> reporter: in the hot and dangerous middle east, she held her own in the company of men. a captain and a commander whose devotion never wavered. >> she inspired people. and that's maybe why she made such a great commander. she inspired her troops. she inspired those that worked for her to want to do well. >> reporter: she was captain

army veteran debbie moore was one of her best friends. >> lynn was very intelligent. she knew how to bring out the best in people. i just loved her. she was someone to be inspired by. she inspired people. >> reporter: so she had a big role in the military. >> very big role, yeah. >> reporter: she was in charge of the air defense artillery in saudi arabia. >> when they were in saudi and we had the patriot missiles, she would be the one that would make that decision on what was coming in, if it needed to be taken out of the sky. >> reporter: captain reister earned medals and promotions and the loyalty of the men and women under her command. that loyalty cut both ways, according to her assistant megan ayers. did she take good care of her soldiers? >> absolutely. she did welfare checks where you would, you know, she would visit with families. she would meet with the different wives and things like that. >> reporter: was she the perfect candidate for the army? >> she was, in my opinion. she didn't let stress get to her too much. i think that she was probably

ever worked under. >> reporter: lynn grew up with a brother and two younger sisters in the military town of pensacola, florida. while she was away at school, she sent her sister some advice on tape for her 16th birthday. >> don't argue. avoid arguments. just be happy. don't let anyone spoil that for you, and you'll be happy and you'll find it in your heart. anyway, i hope that helps. >> reporter: she graduated with an officer's commission from norwich university in vermont, one of the oldest military colleges in the country, and then began the globetrotting life of a soldier. >> i met lynn over in germany. >> reporter: debbie and lynn were both stationed over there. they met at a birthday party through mutual friends. >> i snapped a picture of the four of them sitting there at the table. >> reporter: young women serving their country, savoring life overseas. and being surrounded by guys in uniform, sometimes love entered the picture. it certainly did for lynn.

how did lynn and roger meet? >> they met over in germany at the k club. >> reporter: is that an army club? >> that is an army club. it's in ansbach. and we would go there on saturday nights because on saturday nights they had country music. >> reporter: sergeant roger reister and lynn hit it off at once, and the romance blossomed. >> lynn was a wonderful person. she had a smile that just lit up the room. >> reporter: as a military wife, when i heard that roger was enlisted and lynn was an officer, that's a no-no in the military. >> yeah. back then it wasn't as critical as it became a couple years later. he was a charmer and she -- [ laughter ] she fell in love. >> reporter: and they got married. debbie liked the fact that he was an elvis fan. >> and i was, like, amazed. i was like, really? you're into elvis presley, too? i was kind of surprised by that, yeah. so, yeah. he was a lot of fun. yeah. >> reporter: roger admired lynn's devotion to her country and her strength. >> you have to be mentally strong. with the military, especially

you have to be, you know, mentally strong. be able to go toe-to-toe with some of the men. >> reporter: lynn and roger had chosen a soldier's life, and that meant a marriage full of separations. roger even missed the birth of his son triston. >> it was unbelievable. as soon as i came back, i stepped off the bus and she held him and she said, this is your son. and that was a really -- it was really a great moment. it really was. and i just held her and held him at the same time. >> reporter: was he a good dad? >> he was. he would bring him up to visit. and, you know, they would play. and he seemed very happy being a dad. >> reporter: when triston was 4, the family was stationed at ft. bliss in el paso, texas. and it was lynn who got called away. >> lynn found out she had to deploy to saudi arabia. >> mm-hmm. >> reporter: you were going with her? >> yes, ma'am. >> reporter: was she okay with that? i mean, she had to leave triston behind. this is her first deployment without him, correct? >> to the best of my knowledge,

yes. i remember her telling us that it was hard, that she was having a hard time with it. she was sad, and that she just kept telling him that she'd come home. it won't be that long. >> reporter: and it was how long was the deployment? >> it was about six months. >> reporter: and then she did 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 really looking forward to. >> reporter: just days before moving time, lynn was saying goodbye to ft. bliss. lynn was having a going away party? >> any time a commander resigns a command, the unit will put together and buy her a going away gift. usually a plaque or something to commemorate the accomplishments of the unit. >> reporter: megan didn't go but her husband did. >> my husband came home. and i asked how it went. you know, did she like the gift? and he said, you know, she never showed. and that was very odd. >> reporter: something else was odd. roger had been calling lynn at home throughout the day.

no answer. late that afternoon, he came home from work with triston, and it was all too clear why lynn hadn't answered the phone. >> 911. >> oh, oh. i just got home. my wife is dead. >> reporter: lynn armstrong reister, mother, soldier, beloved commander, was in her bedroom, lying dead in a pool of blood. when we return -- >> my first instinct was to grab triston and run out of the house. >> it almost made me sick. i was on the floor. >> where will investigators start? >> it could be a neighbor. it could be a lover. it could be anybody. >> you had a killer on the loose.
