Homicide detectives are investigating the death of a man found fatally shot in a Hacienda Heights backyard Sunday afternoon.

Coroner’s officials didn’t release the man’s name on Monday because his next of kin hasn’t been notified.

A neighbor called deputies about 1:45 p.m. to report seeing someone lying in the large backyard of a home in the 14400 block of Clark Avenue, Sheriff’s Sgt. Rick Thurlo said.

Deputies and paramedics discovered the victim, a 34-year-old Latino, suffering from an apparent gunshot wound, according to department spokeswoman, Deputy Crystal Hernandez.

Paramedics pronounced the man dead at the scene.

Hernandez said according to witnesses, a single gunshot was heard in the area but no suspects or vehicles were seen.

Anyone with information is asked to call the Sheriff’s Homicide Bureau at 323-890-5500. Tips may also be submitted anonymously to L.A. Regional Crime Stoppers at 800-222-8477.
