Investigators believe the gunman in a deadly New York City shooting was targeting the NFL headquarters, as he entered the building where the offices are located. A note on his body claimed he had CTE from football.

The Rudin family, which owns the building and Rudin Management, said in a statement that one of their employees was a victim of the shootings but did not disclose the person’s name at the request of relatives. Police officials said a woman was found dead on the building’s 33rd floor in Rudin’s offices.
