the Dee Warner case reminds me of one of the first no body convictions in Dane County back in the 80s. Roth Homburg was last seen in 1983 or 1984 after finding out her husband was having an affair. Husband claimed she left, police never believed it. Finally a trial in 1989 after the husband's affair partner agreed to testify the husband told her he murdered Ruth- he was also embezzling money.
the police always thought she was did, as did her children, because all of her belongings were there - although later some went missing. And she never ever contacted her children, that was a big point at the trial.
The husband had a business with a high heat furnace where a body could easily be disposed of without a trace. He still claimed she left, and has refused to explain what happened even though he was convicted. I am pretty sure he is still alive and in prison.
