LOUISVILLE, Ky. (AP) -- A Kentucky coroner has identified the body of a man found in the stable area of Churchill Downs hours after the Kentucky Derby as a race track worker.

Jo-Ann Farmer of the Jefferson County coroner's office on Sunday identified the victim as Adan Fabian Perez, 48, a Guatemala native.

Farmer said he was identified by his 19-year-old son, who also works at the track.

Police spokeswoman Alicia Smiley said the victim "did sustain injuries that lead us to believe he was involved in some type of altercation."

Louisville Metro Police say the death is being investigated as a homicide.

Perez' body was found in a barn but authorities say there appears to be no connection to the track.

An autopsy is scheduled for Monday.
