Peter Rostov was a sex trafficker who kidnapped one of the daughters of former KGB analyst Nikolas Brezin as insurance for a failed attempt to bribe Brezin into filling him in on police scrutiny of his business.
When Brezin's daughter tried to escape in New York City, Rostov beat and raped her as punishment. Brezin learned about this but thought his daughter had also been killed, prompting him to travel to New York and fatally poison him with ricin. (L&O: "Fallout")
