NEW YORK (AP) – The college student suing Kevin Clash for $5 million says he didn’t know he was the man behind Elmo when they met on a gay chat line when he was 15. Cecil Singleton says he was “shocked” when he found out what Clash did for a living. He says he and Clash had sexual contact for two weeks, but didn’t sleep together. He says Clash would go on gay chat lines for underage boys and meet them for sex. He says he hadn’t planned on coming forward until he heard another man accuse Clash of having sex with him when he was 16. That man later took back his accusation and said he wasn’t underage when they had a consensual relationship. Singleton’s lawyer says he’s been contacted by two other potential victims. Clash has resigned from “Sesame Street,” saying he’s “deeply sorry to be leaving.” Sesame Workshop says it was “a sad day for Sesame Street.”
