A terrifying Midtown Manhattan rampage unfolded Monday evening when a gunman armed with an M4 rifle stormed a Park Avenue office building, killing four people — including NYPD Officer Didarul Islam — before taking his own life.

 The shooter, identified as Shane D. Tamura, 27, of Las Vegas, was reportedly trying to reach the NFL’s offices but ended up opening fire in another part of the building.

Tragedy of Midtown Manhattan Rampage

The violence erupted around 6:30 p.m. at 345 Park Avenue — a 44-story high-rise that houses major tenants like the NFL, KPMG, and Blackstone. NYPD Commissioner Jessica Tisch said Tamura arrived alone in a black BMW and entered the lobby carrying a high-powered M4-style rifle. 

He shot Officer Islam, who responded to the emergency, along with two other victims on the ground floor — Blackstone executive Wesley LePatner and security guard Jorel Etienne.

Mayor Eric Adams revealed Tamura was targeting the NFL, blaming it for his supposed diagnosis of CTE (chronic traumatic encephalopathy), a brain disease associated with repeated head trauma.

“He did have a note on him… He appeared to have blamed the NFL for his injury,” Adams said on CBS Mornings. “He wanted his brain studied for CTE.”

Though Tamura played high school football, he never went pro.

NFL, Blackstone React to Tragic Loss

The NFL confirmed one of its employees was seriously wounded. Commissioner Roger Goodell told staff the building would remain closed Tuesday.

“We are deeply grateful to the law enforcement officers… and to Officer Islam, who gave his life to protect others,” Goodell wrote.

Blackstone mourned the loss of LePatner in a public statement, calling her “brilliant, passionate, warm, generous, and deeply respected.”

Mayor Slams Gun Laws as NYPD Investigates Motive

Adams criticized the shooter’s ability to legally obtain firearms despite concerns about his mental health.

“We have strong gun laws here, but many of our neighboring states have lax gun laws,” Adams said.

Investigators discovered a three-page note in Tamura’s wallet referencing CTE. NYPD teams are now in Las Vegas executing search warrants and tracking the origin of the recovered firearms.

Heightened Security and Grief Counselors

The NFL is offering grief counselors and increased security as law enforcement continues its investigation. Meanwhile, bullet holes and blood stains left a grim reminder of the chaos as Mayor Adams prepares to attend a vigil for the victims in Bryant Park.

“If the security guard had reached the freeze button, it could have stopped the elevator,” Adams said. “But he was assassinated behind the counter.”
