Honestly, it’s not a stretch to assume a man who has a history of physically assaulting (with proof) is responsible for that woman’s disappearance when she turns up missing.
Obviously public accusations can go too far, but 99% of the time when a woman comes up missing who has a boyfriend or husband known to physically abuse her, he did it. (Reference: hundreds of stories on Websleuths, Dateline, 20/20, newspapers everywhere, websites with statistical data on Intimate Partner Violence).
If you don’t want to be the prime suspect in a murder or disappearance, don’t develop of a history of physical assault. Seems like a good plan for any of us to follow.
