Went to prison. she was living with a firefighter, as a matter of fact. one of my brother s supposed fire brothers. reporter: what s your advice to this guy, this firefighter? watch your back, you know. the last two guys involved with danielle, one s dead, one s in prison. reporter: as for dianne, she s now left to reflect on a life with sam that could have been. did you two talk about marriage? yes. reporter: and was that in the cards? oh, absolutely. reporter: did you ever feel like i m being punished for having this affair? oh, yes. i might have said those exact words myself. reporter: it all started in a club with an innocent conversation. mm-hmm. reporter: was it all worth it? falling in love with sam? i would never change having met sam.
Even talking about it with you now i have chills. reporter: those texts, she said, proved just how much danielle hated sam and wanted him out of the way. and she s convinced danielle manipulated michael to feel the same way. do you think that danielle had anything to do with your brother s death? was she somehow directly associated? i think she is. i hold danielle dreher as much if not more responsible than the man that actually shot him. reporter: cindy told detectives she believed hatred wasn t danielle s only motive, that she was also driven by that age-old incentive. i believe it was the money. to divorce him and split half of it is one thing. but to get all of it? i think it was money. i think it was always money. reporter: just over a million dollars, in fact. there was a substantial amount of money that she was going to gain if sam turned up dead.
