LOS ANGELES  The body of a man slumped over patio furniture on his balcony in Marina del Rey was mistaken for Halloween décor last week and remained undisturbed for five days.

Sheriff’s deputies were called to the complex Thursday evening and found the man, Mostafa Mahmoud Zayed, 75, dead. He had been shot through the eye.

“He looked fake,” said Austin Raishbrook, 33, who lives nearby. “It looked like somebody had thrown a dummy over the back of a chair.”

Sheriff’s deputies believe that Mr. Zayed committed suicide, said Steve Whitmore, a spokesman for the Los Angeles County Sheriff’s Department. “Our investigators don’t think there was any foul play here,” he said.
