The NYC gunman who killed four people had a “documented mental health history” - and an active, concealed carry permit for firearms at the time of the mass shooting Monday.
Shane Tamura stormed the Midtown office building which houses the NFL, Blackstone and other businesses, and began “spraying” the lobby with bullets from an assault rifle. Four people - a security guard, an off-duty NYPD cop, and two female corporate executives - were killed before Tamura turned the gun on himself, authorities said.
