Multiple people have been shot and killed at a New York City office building where the NFL is headquartered, according to NYC Mayor Eric Adams.

Tamura, Tisch said, shot four people on the building’s ground floor, including Islam, before proceeding to an elevator. He went to the offices of the real estate company Rudin Management on the 33rd floor, where he shot and killed another person. Rudin owns the high-rise building. Tisch said the shooter then shot himself in the chest.

A New York City police officer and a civilian were shot Monday outside a midtown office building that houses the National Football League and some of the country's top financial firms, police sources told ABC News.
