A man was found dead Wednesday in what appears to have been a suicide at a residential construction site on a lot owned by Mel Gibson.

The Lost Hills Sheriff's Department received a 911 call at 8:09 a.m. alerting authorities to a man hanging from the rafter of a house on Sierra Creek Road in Agoura Hills, Los Angeles County Sheriff's Department Det. Eddie Brown told E! News.

"Detectives along with paramedics arrived at the scene and the gentleman was pronounced dead on arrival. Cause of death will be determined by the Los Angeles Coroner's office," Brown said.

A source close to Gibson tells E! News that the Braveheart star has never lived on the property, where construction of a residential compound has been underway for some time.
