WEST PALM BEACH, Fla. (AP) - A man reportedly fell to his death from a 21-story office building in West Palm Beach.

Police say 24-year-old Brett Hall jumped from the top of the Northbridge Centre building Thursday morning. Police are calling the death a suicide.

Witnesses reported that the man might have lived through the initial fall but didn't survive for long.

It wasn't clear how Hall got to the building's roof. A detective on the scene said only maintenance workers and security guards have access to the area.

The property managers, the Gaedeke Group, said they would not comment until the investigation was closed.
