Officials at the U.S. Court of Appeals have upheld a decision to dismiss three sexual abuse lawsuits filed against former Sesame Street puppeteer Kevin Clash. The gay actor, 53, was forced to resign from his role as the voice of lovable character Elmo in 2012, after he was accused of engaging in sexual activities with college student Cecil Singleton when he was just 15. Further complaints followed, but three lawsuits, including Singleton's, were thrown out of a New York court last year (May13) due to the statute of limitations, which gives alleged sex crime victims three years to file once they turn 18 - a deadline all plaintiffs failed to meet. Lawyers for the three plaintiffs appealed the ruling, but the case was dismissed again earlier this month (Apr14) in the U.S. Court of Appeals, according to People.com. One other lawsuit, filed by Sheldon Stephens, is still pending, even though the alleged victim recanted his story soon after going public with his claims of sexual abuse, admitting the relationship was consensual.
