LOS ANGELES – Authorities are investigating whether an electrician intentionally leaped to his death from the 53rd floor of Los Angeles’ tallest skyscraper onto an intersection humming with a normal weekday’s bustle, the coroner said Friday.

Joseph Sabbatino, 36, of Palmdale plunged about 800 feet from the unfinished Wilshire Grand Center on Thursday. It was his second day on the job.

Sabbatino’s father, Vance Sabbatino, told KABC-TV that his son struggled with depression and had been prescribed medication.

His death was reported as a possible suicide but no note has been found, said Ed Winter, Los Angeles County’s assistant chief coroner.

Sabbatino’s body landed either near or on the rear of a passing car, but the driver wasn’t injured.

It took some time for people below to realize the horror of what had happened, said Los Angeles Times photographer Mel Melcon, who was on assignment at the building.

“No one thought it was a body,” Melcon told his paper. “We heard no screams.”

Sabbatino had taken off his hard hat and had not been wearing a safety harness because it wasn’t required for the bottom floors he’d been working on.
