A cross-country drive, a Midtown office rampage, and a note blaming football injuries. Here's what we know so far about the NYC shooter and his victims.

Four people were killed, including an off-duty New York City police officer, when a gunman opened fire in an office tower before fatally shooting himself, officials said.

Barriers were erected in front of the ritzy Midtown Manhattan office building where a crazed gunman killed four people Monday, with access being restricted even to some who work there.

The gunman, who said in a note he believed he had CTE, targeted skyscraper that houses the NFL's headquarters.

We have reason to believe he was focused on the NFL agency that was located in the building,” New York City Mayor Eric Adams said during an interview on MSNBC Tuesday.

Occupants of some buildings near the scene of a shooting in midtown Manhattan are being allowed to leave following lockdowns. NBC News' Steven Romo reports a sense of relief spread through crowds gathered near the shooting scene after police announced the gunman is deceased.
