Adams: Shooter targeted NFL headquarters

According to ESPN, New York City’s Mayor Eric Adams said on Tuesday that the gunman was trying to target the headquarters of the NFL, but mistakenly took the wrong elevator.

Investigators believe that after shooting several people in the lobby, Tamura tried to get to the NFL offices in the building but he entered the wrong set of elevator banks.

Police reported that Tamura had a history of mental illness, and a note found on the shooter’s body suggested that he had a grievance with the NFL over a claim that he suffered from chronic traumatic encephalopathy, or CTE, per ESPN.

Instead of the elevator taking Tamura to the NFL offices, he was taken to Rudin Management, the company that owns the building, where he continued to fire his weapon, per CNN.

The NFL Players Association released a statement on Tuesday, extending condolences to those affected by the shooting at the league’s headquarters, saying that it is deeply saddened by the attack.

“345 Park Avenue is part of our football family, and we at the NFLPA extend our sincere condolences and support to the people who work in this building and to the families of those who lost their lives,” the association said.

“We also want to express our deep gratitude to the law enforcement and emergency personnel who responded to those impacted,” the statement continued.

What do we know about the shooter?

During a press conference on Monday, New York City Police Commissioner Jessica Tisch said that Tamura was a 27-year-old Las Vegas resident, per Fox News.

The shooter had traveled across the country, driving across state lines. His car was seen as recently as 4:24 p.m. on Monday in Columbia, New Jersey, just hours before the attack.

Fox News reported that Tamura had a concealed carry permit, which was issued in June 2022 and is valid for five years. The gunman also had a private investigator license and has a record of a misdemeanor for trespassing not amounting to burglary in 2023.

Tamura played football in high school at Granada Hills Charter in Granada Hills, California, located around 25 miles northwest of Los Angeles. He also worked at a Las Vegas casino as a security guard, per Fox News.
