Betty Lou Beets
The bodies of Beets' fourth and fifth husbands were found under a
wishing well in the yard of her mobile home at Gun Barrel City,
Texas. They had been shot in the head, execution-style. She had
also shot her second husband in the back of the head, but he survived
and she was only convicted of misdemeanor assault for that one.
Feminist supporters claimed she was justified in killing because of abuse.
