Lt Fred Corral says the man was found dead at 5:30 am today. Los Angeles police responded to the home on the 9000 block of Oak Pass Road in west Los Angeles after a 911 call.
Sgt A Bone says Moore was not home at the time, and the man is not a family member. He was associated to someone with access to the pool. His identity hasn't been released.
A small crowd was around the man's body when police officers arrived. Authorities say Moore's children have been having pool parties at the home, but it's unclear if a party was ongoing when the drowning occurred.
