Tommy Bandolce is the abusive boyfriend of Jesse Sturgis. His abuse led to her pursuing an affair with married man Michael Provo.
When Provo raped her for breaking it off and she wasn't intimidated by the fact he was a cop, he killed Bandolce to frame her for the murder. The conspiracy was found out, and Jesse was released, with Provo being arrested and convicted for murder. (SVU: "Beautiful Frame")
