Oliver Tunney is a convicted sex offender and pedophile from New York City. A former children's birthday clown, he spent five years in Sing Sing Correctional Facility for molesting the children for whom he performed.
Paroled sometime around 2001, Oliver, currently working as a painter, was briefly a suspect in a string of multiple kidnappings, rapes, and murders after being arrested for parole violation. He was subsequently cleared of all charges, but was also wanted for alleged molestations in Norwalk. The real perpetrator of the string of crimes, Clayton Mills, was later arrested after being lured out by police. (SVU: "Countdown")
