New York Gunman Was Targeting NFL But Went To Wrong Office, NYC mayor says

New York City's Mayor Eric Adams says a gunman who killed four people when he stormed a skyscraper in the heart of the city on Monday evening, left a note that appeared to blame the National Football League NFL, for a brain injury.

The attacker, 27-year-old Shane Tamura of Las Vegas, shot himself dead, after opening fire in a building where the American football league has its headquarters, but went to a different part of the building after taking the wrong lift.

Adams said the gunman was carrying a note in which he blamed CTE, a brain disease triggered by head trauma, for his mental illness.

Ex-teammates have told US media Tamura played football as a teenager, but did not play in the NFL.

A New York City police officer, who was working as a security guard at the building, was among those killed.
