more sinister was going to happen that day. >> in fact, nothing happened. janos went home. but he came back here to mary ann's house a few days later, lewin and wallace learned. it was on the friday before the murder. he met with mary ann alone and had an epiphany. it was something he referred to in one of the conversations the police recorded between janos and mary ann. >> remember that morning that i left, friday? i remember. it never clicked until i came home. sometimes i'm slow on things, you know, but it clicked. >> clicked? what did he mean by that? >> he realized, you know what? she doesn't love archie. she's not going back to archie because she loves him. she loves me. so if i could just find a way to get rid of archie, i don't need to kill myself. if i get rid of him, i get the girl, she gets the security, and he's out of the way.
