Victor Paul Gitano was a villain from Law and Order: SVU. Gitano was a sadistic pedophile, and very proud of it. He lured kids in, then raped, tortured and killed them. He didn't discriminate by gender which arguably made him even more disturbing.
When trying to hunt Gitano down, things didn't quite go as planned and he managed to kill one of the two kids he had with him in a subway station full of people by slashing his throat, then almost killed Benson the same way - when they cornered Gitano in a warehouse, he managed to get behind Stabler and held him at gunpoint with a shotgun.
Gitano, despite knowing he'd get caught or killed, outright boasted that he killed the other child he had and bragged that she was a "slut" and a "real little whore" before killing her, even though he never got the chance to molest her. Fortunately for Stabler, Gitano is promptly killed by a police sharpshooter.
