Authorities are piecing together the chilling events that unfolded on July 28 when 27-year-old Nevada resident Shane Tamura opened fire inside a Manhattan skyscraper, killing at least four people before turning the gun on himself.
Tamura entered the lobby of 345 Park Ave. — home to the NFL’s headquarters and several major financial firms — armed with an M4 rifle. According to NYPD Commissioner Jessica Tisch, he “immediately” began shooting, fatally wounding four, including NYPD Officer Didarul Islam. Officials say Tamura had a documented history of mental health struggles and appeared to act alone.
New York City Mayor Eric Adams revealed Tamura carried a note blaming the NFL for what he believed was CTE, a brain injury often associated with contact sports. Investigators believe the league headquarters was his intended target.
Surveillance footage shows Tamura arriving in a black BMW registered in his name. Police traced the vehicle’s cross-country route from Nevada through Colorado, Nebraska, and Iowa before it reached New Jersey hours ahead of the attack. Inside, officers found ammunition, a loaded revolver, and prescription medication.
The shooting began in the lobby, where Tamura gunned down Officer Islam, a security guard, and two civilians. He then rode an elevator to the 33rd floor, where he continued firing before taking his own life. Officials suspect he may have mistakenly reached the offices of Rudin Management instead of the NFL’s floor.
NFL Commissioner Roger Goodell confirmed one employee was critically injured but said all others were accounted for. “Our thoughts are with the victims and their families,” he wrote in a staff memo.
Police are still investigating Tamura’s motive, with early evidence pointing to a disturbing mix of mental illness and perceived grievance against the NFL.
