Tito Cabassa is a thug responsible for the rape and sodomy of Anne-Marie Liscomb, and was originally a suspect in her murder. It was revealed his accomplice, prostitute Melinda Whitman, killed Anne-Marie after she was raped, out of a horrifically projected sense of jealousy.
When the truth was found out, Cabessa offered a confession to rape to sell Whitman out. The prosecution took the deal, and Cabessa was imprisoned for rape on a more lenient sentence for his cooperation. (L&O: "Tango")
