I believe he did murder his wife. The fact that he has been caught lying about the timeline and the suspicious death of his 3rd wife are strong factors. HIs first wife admits he cheated on her, wife number 2 said he cheated with wife 3 and was physically abusive and the missing wife was his girlfriend when wife 3 died. Wife 3's new autoposy says foul play. This guy is a cop who knows how to conceal, as well has friends in places that could easily skew reports, etc to make him look incident. A man of his character only hones his craft, he never rehabilitates.
