Twenty years after his manslaughter conviction, "Party Monster" Michael Alig says he's trying to reinvent himself. In 1996, the club promoter and his roommate Robert "Freeze" Riggs killed acquaintance, Andre "Angel" Melendez. They cut up Melendez's body and threw it in the Hudson River. They also talked openly about the killing in an effort, he now says, to put the burden on someone else. "I know that nothing I ever do is going to erase the past," Alig told InsideEdition.com.
