reporter: investigators talked to michael s brother chris the son who d arrived at the scene later with their mother becky. chris seemed to have his life together in a way that michael didn t he had a job even his own house. that morning he was helping his mom at the therapy center where she worked. your mom picks you up about what time? i got up at 7:00, brushed my teeth. she she pulled up 7:10. then you go to work with her? yes. reporter: then they asked him about michael. chris said he knew his brother took drugs but he said michael wouldn t have killed anyone. do you think your brother did this? or do you think somebody? absolutely not. i don t think my brother has it in his heart. i just want to make sure that that that at this point, brotherly love is not outweighin common sense. well because i just saw some stuff in your brother just talkin to him for about 20 minutes. and i m sittin there goin , what? people get on methadone. they don t have a
he d gotten there around 8;30 that morning only to find his house had been burglarized and he d promptly called his mom. but he hadn t called the police, which seemed a bit strange to investigators. what s more there was no forced entry to that residence. reporter: there wasn t? there was no forced entry. reporter: that was odd too, and they were about to learn a lot more about michael. he was becky s oldest son. he and his brother chris were from a prior marriage. and michael came with a history of trouble, mostly drugs. so, that s gotta make your nose twitch a little bit. most definitely. he s on the scene when we get there. he s had a lotta problems in the past with with with drugs. so that raised a lotta red flags. reporter: opportunity to get quick cash? most definitely. drug habit? make a buy? you know, they gotta get money. and the best way to do that is is burglaries, you know? get the quick cash. reporter: did you have trouble with drugs at the time
oh yeah. oh yeah. we re looking at some premeditation and some planning here. reporter: but edmunds had to consider the source of the story. of course, jailhouse stories are always troublesome because they re trying to do themselves some good. definitely. reporter: one thing the brother said was easy to confirm, he didn t do the hit job. he was in jail at the time of the murder. so if becky was behind it all, who helped her? jacobs said there was another member of the family investigators should look at, becky s son chris. the young man with his own house. jerry had been staying there before he was behind bars, and said chris also knew about becky s affair and how desperate she was. would call christopher almost every night and cry and tell him stuff. and he would get off the phone. and i m like, is that your mom? and like, yeah. what s wrong with her? you know what it is. you know what s wrong. i m like, yeah. i was like, david again? he s like, yeah, david ag
but to this veteran cop, david s emotions seemed real. and in the end, edmunds had no reason to believe that david played any role in a plot to kill kay. we had no evidence whatsoever to prove that he knew or was involved in any of this. i really don t wanna come have to come back, you know? come back to you with somethin else that comes out that you haven t told me. you know what i m saying? oh, well, you can ask me anything. i don t know what else you need to hear from me. i m not tryin to keep anything from you guys. i promise. reporter: before edmunds turned off his recorder, david did share one tidbit. something that linked up with what becky s brother had told edmunds earlier. it was the name of the other person becky had confided in about her affair with david. becky s son, chris. i asked her who knew. you know, who else knew. and she did tell me that christopher knew that she was with somebody else. i don t know if that means anything or not. reporter: sheriff s
i don t know if that means anything or not. reporter: sheriff s deputies spent a lot of their investigation looking at the relationships in becky s life. first her son michael. then david. but it was becky s relationship to her other son chris that would prove to be the most intriguing. it was a real, real strange mother/son relationship. when his mother called, he would drop everything and go to mom. whatever she wanted, he was there. reporter: becky, investigators discovered, doted on chris and showered him with extravagant gifts money, a motorcycle, a car. nothing was too expensive for chris. not even the house he lived in. it was a house purchased by his mother. eighteen year old kid with his own house? correct. that s kinda strange, you know. was he a mama s boy? well, i mean, i guess he was a mama s boy, you know. anything he needed, he got. reporter: but according to michael, becky s over-the-top generosity always seemed to come with strings attached. it wa
