John Kennelly

John Kennelly is one of the most well-known child predators that appeared on Dateline's To Catch A Predator. At the request of a decoy posing online, he entered a home in suburban Washington completely naked. After being grilled by Chris Hansen, he seemed to have learned his lesson, but less than 24 hours later, he made another date with a decoy to meet at a nearby McDonald's for sex.
