black widower 

A dude who's had a long list of marriages, only to have each of his consecutive wives die and/or disappear under questionable circumstances.

Aside from execution, the only sure way to stop a black widower from continuing his ghastly lifestyle is to have him marry a black widow. Further explanation unnecessary.
