On Friday, July 29, ABC 20-20 aired the history of Felix Vail, who would be caught for murders committed over 50 years ago, starting in 1962 in Louisiana.
USA Today has a supplementary detailed history of the episode, called “Gone”, which re-aired as a bonus Jan. 30. (Maybe it should be "Gone, Baby Gone".)
Vail apparently didn’t want wives to keep actually bearing him children whom he would have to support.
The story was accelerated when a home in Mississippi was sold and the new female owner found evidence left behind in an attic.
This reminds me of Robert Durst and his “Killed them all, of course”.
