Gunman kills four in New York skyscraper rampage

NEW YORK — A gunman armed with an assault-style rifle killed four people inside a Manhattan skyscraper that houses the headquarters of the NFL and offices of several major financial firms and then fatally shot himself, New York City officials said on Monday.

One of the four victims killed in the gun violence was a 36-year-old New York Police Department officer who immigrated to the United States from Bangladesh. Authorities offered few details about the three other victims killed by the suspect.

New York Police Commissioner Jessica Tisch said the gunman, identified as Shane Tamura, a 27-year-old Las Vegas resident with a history of mental illness, had driven cross-country to New York in recent days.

The gunman was believed to have acted alone, Tisch told reporters.

The shooting spree in the evening rush hour began in the lobby of the Park Avenue tower in Midtown Manhattan, then shifted to the upper-story offices of a management company as the suspect took the elevator to the 33rd floor.

The bloodshed came to an end when the gunman fatally shot himself in the chest, Tisch said.

The skyscraper at 345 Park Avenue houses the offices of several financial institutions, including Blackstone and KPMG, as well as the headquarters of the National Football League.

New York Mayor Eric Adams said on Tuesday that the gunman was trying to target the headquarters of the NFL but took the wrong elevator.

Investigators believe Tamura was trying to get to the NFL offices after shooting several people in the building's lobby but accidentally entered the wrong set of elevator banks, Adams said.

In another incident on Monday, a gunman opened fire outside a casino in Reno, Nevada, killing three people before police shot the suspect and arrested him, officials said.

The suspect had no known connection to the victims, and it was unclear if he was a guest or an employee at the Grand Sierra Resort, one of Reno's most prominent venues.

Police were still trying to determine a motive for the shooting.
