A new Netflix documentary, “Killer Sally,” directed by filmmaker Nanette Burnstein, covers what led Sally McNeil to kill her husband Ray McNeil. The couple were both champion bodybuilders. But their volatile relationship came to a head when Sally shot and killed Ray in their California apartment in 1995. Sally says she killed him in self-defense. However, prosecutors said she had her own history of violence. Sally was convicted and served 25 years in prison.
