when they asked him about dennis, the fiance. that is a loaded question. uncomfortable. they were having problems. diane had complicated relationships with dennis and ray. just as they had done with dennis, police fingerprinted ray and took a dna swab. sharon told the detectives diane had a date with a man the very night she was killed. they couldn t figure out who the man was but they tracked down every man they met from the dating service it s just lunch. i interviewed every date she had through that service. police wondered if diane was strangled by a man she met through the dating service?
the first wife said that he could not get aroused sexually unless he was choking her. and that he choked her when they had sex. reporter: and the second wife? second wife confirmed that he also choked her while they had sex. i mean, i will say that he does tend to put his hand on my neck. any time i feel like my airway s getting restricted, you know, then and he always lets go. reporter: so the strange and potentially dangerous fetish, but was that all it was? isn t it possible though that he didn t really want to kill diane holik? it s my belief that he did. that just choking and not killing, it was no longer enough. it wasn t enough anymore. reporter: and why was she so sure? because of what turned up during a forensic analysis of tony russo s computer.

and yet that very week, said her friends, diane told her she still didn t know what to do. she was back and forth? yeah. emotionally a roller coaster. we couldn t see how it would work and none of us could see how it would work. she told sharon she made a date with another man. we said if you are still wanting to do these things, you are not ready for that. she had her house for sale. she was going to downsize. if she didn t get married to dennis she would downsize because the house was way too big. waffling on her plans with dennis, date with another man, anita said she had seen dennis angry. after diane was murdered she wondered. maybe he just lost control this time and killed her. that was my first thought. the detective asked dennis to come into the station where he agreed to speak to him without the aid of a lawyer. the detectives focused on the timeline. they believed diane had been killed the stormy thursday afternoon or evening. her body was discovered 5:30 p.
