Police have identified the body found yesterday at a Churchill Downs barn, whom they believe was murdered. Adan Fabian Perez, 48, was reportedly a groom for trainer Cecil Borel and had been licensed by the Kentucky Horse Racing Commission since 2008. The Guatemala native lived on Churchill Down's backside, where his body was discovered. The body was identified by Perez's son, a fellow Churchill Downs worker. Details of the death haven't yet been released, the Courier-Journal notes.
