found the actual projectile itself, right on the edge of the sidewalk. and you didn t find a tossed weapon in the vicinity? no, no weapons. reporter: the shooter had vanished without a trace. but you had more questions, didn t you? we did, indeed. reporter: but those questions would be left for jimmy edmunds, whose investigation into kay parsons murder had suddenly become a lot more complex. here i ve got two neighbors, you know, one has been beaten to death and the other one has just gotten shot. and they both worked at healing hands. do you believe that the gunman who has wounded becky is also the person who s broken in and fatally beaten miss parsons? of course that comes to mind. i mean, of course it does. it s just too much of a coincidence. reporter: and nothing about this shooting took the heat off becky s son michael. what s the working theory? the working theory still is, michael s still pretty high up on the list. somebody s looking for some money. so
reporter: so michael s brother confirmed the troubled young man ran with a shady crowd. investigators were all ears. reporter: does his association with the house, his back story, make him a person of interest to you? he s definitely a person of interest. reporter: the deputies kept michael at the station for nearly three hours but they didn t hold him that day. he gave them a number for his alibi witness, that friend he d gone to see that morning. would he vouch for michael? another mystery. we had some blank checks in one of our offices that disappeared. and a new theory of the crime. we didn t know if they were in this together or what.
i was expecting to hear that it was michael really cause, you know, i ve been learning so many things about michael and his past and all of that. you haven t had any discussions with michael about like you ve had with christopher? not like with christopher, no. no. cause me and christopher are a little bit closer than me and michael. do you know if she ever talked to michael about it? no, i don t. have a seat right here. reporter: still, edmunds decided it was time to bring in michael for a second round of questioning. and this time, the investigator turned up the heat. michael, it s over, okay? i m not playing games anymore. reporter: at first, michael said he didn t even know that becky and david were having an affair. i know about the affair with your mom and david. my mom and david? don t play stupid with me. don t play stupid with me.
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 at this point, brotherly love is not outweighing 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 any money. and they not workin . well how they going to get money? i agree on that. i do agree on that. well, out of everybody that your brother hangs around with who would be the most likely to do somethin yes, uh-huh. yeah
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 was that, hey, i m going to need something from you. here s the keys to your new car. hey, i m going to need something from you. here s your house. hey, i m going to need something from you. here s an envelope full of money. reporter: and whatever becky asked for, chris would eagerly deliver. he said, it may be very hard for you to understand, but i would do anything in this world for my for our mother. reporter: could anything have included killing his mother s romantic rival? michelle amerson, who knew the family well, says over the last several years chris had grown distant. she worried he was heading down a dark path. he had changed a lot. so we were we weren t around him a lot. when you say, he changed
