A man stalked through a Manhattan office tower firing a rifle on Monday, killing four people, including a New York City police officer, and wounding a fifth before taking his own life.
The shooting took place at a skyscraper that is home to the headquarters of both the NFL and Blackstone, one of the world’s largest investment firms, as well as other tenants.
The gunman, identified by authorities as Shane Tamura of Las Vegas, had a ‘documented mental health history,’ according to Police Commissioner Jessica Tisch, but his motive was still unknown.
“We are working to understand why he targeted this particular location,” Tisch said.
The rampage happened at the end of the workday in the same part of Manhattan where the chief executive of UnitedHealthcare was gunned down outside a hotel late last year.
Surveillance video showed the man exiting a double-parked BMW just before 6.30 p.m. carrying an M4 rifle, then marching across a public plaza into the building. Then, he started firing, Tisch said, killing a police officer working a corporate security detail and then hitting a woman who tried to take cover as he sprayed the lobby with gunfire.
