The man who unleashed chaos inside a Midtown Manhattan office tower on Monday has been identified as Shane Tamura, a 27-year-old licensed private investigator from Las Vegas who once dreamed of a life in football.
Authorities say Tamura arrived in Manhattan by car on Monday and walked into 345 Park Avenue with a concealed weapon permit issued by the Las Vegas Sheriff’s Department.
What followed was a terrifying and targeted shooting spree that police now believe was premeditated and likely suicidal.
‘It appears that he knew it would be his last stand,’ said CNN chief law enforcement analyst John Miller, a former NYPD deputy commissioner. ‘He fully intended to shoot his way through the lobby and make his way to that target – whatever that might have been.’
The building, home to major corporate tenants including the NFL’s headquarters, became the scene of a frantic lockdown as gunshots echoed through the corridors and heavily armed police teams swarmed the floors.
While the league’s offices are housed in the tower, sources confirmed Tamura was not on the NFL floor and that no known connection has yet been established between the shooter and the sports organization.

Still, his past raises haunting questions.
Tamura grew up in Hawaii, where he attended high school and was immersed in a life dominated by sports.
He was a promising football player in junior varsity, obsessed with the game and once on a path that suggested a future defined by discipline and teamwork.
But in the years after he left the field, Tamura’s life became murkier.
He eventually relocated to Las Vegas, where he earned a private investigator’s license and obtained a concealed carry permit to carry firearms, both legally granted through Nevada’s Sheriff’s Department.
