NYC Mass Shooting: 4 Killed, Including Police Officer

A 36-year-old married police officer and three other people were shot and killed by a crazed gunman who stormed a swanky Midtown skyscraper early Monday evening — sparking mayhem in Midtown before turning the gun on himself, police said.

The 27-year-old maniac, identified as Las Vegas resident Shane Tamura, barged into the 44-story building — which houses Blackstone and the NFL headquarters — armed with a rifle and opened fire at around 6:30 p.m. during the evening rush, cops and law enforcement sources told The Post.

Tamura, who authorities said had a “documented mental health history,” unleashed his rampage after setting foot in the lobby, first gunning down officer Didarul Islam, NYPD Commissioner Jessica Tisch said at a Monday evening press conference.

Tamura then fatally shot a woman who was hiding behind a pillar as he continued “spraying” the lobby of 345 Park Avenue with bullets, Tisch said.

The lone gunman didn’t stop there as he marched to the elevators and pumped a bullet into a security guard who took cover behind a desk, police said.

In a chilling moment of apparent mercy, the wacko spared the life of a woman who came face to face with the killer as she exited an elevator, according to Tisch.

Tamura then took the lift up to the 33rd floor, home to Rudin Management offices, where he “fired as he traveled,” striking and killing one person before shooting himself in the chest.

Tamura was seen splayed out on the ground, apparently already dead, in a shocking photo obtained by The Post.

Another man was also shot in the lobby and survived his injuries.

A witness on the first floor recalled that “it sounded like a barrage of shots …Like an automatic weapon. Like a high-capacity weapon.”

“I was at work and this guy came in with an assault rifle and started shooting,” a man, who was gasping for air outside 3, told The Post shortly after the bullets started flying.

Tamura launched the mass shooting after driving across the country, police said.

He crossed into the Big Apple from New Jersey earlier Monday afternoon then drove to 345 Park Avenue, parking between 51st and 52nd streets, according to Tisch.

Chilling images showed the gunman calmly strolling across the building’s entry plaza with a rifle at his side before carrying out the carnage.

Footage posted to social media shows bystanders running for their lives outside the building and workers were also later seen filing out of the high-rise with their hands up.

Sources said Islam, the officer, was shot at in the back and died at a hospital.

With sirens blaring in the background, three cops dragged an injured woman in a dress away from the front of the building, according to disturbing footage.

Tamura is believed to have acted alone.

“His motives are still under investigation. We are working to understand why he targeted this particular location,” Tisch said.

Police recovered Tamura’s bloodstained long gun, a Palmetto State Armory AR-15 rifle.

A vehicle with Nevada plates registered to Tamura was found at the scene.

Cops searched his car and found a rifle case with rounds, a loaded revolver, extra ammunition, magazines, a backpack and medication prescribed to him.

Sources said Tamura was a security guard at a Las Vegas casino and didn’t show up for work Sunday morning, setting off alarm bells.

The gunman had a concealed firearms permit from Las Vegas with a 2027 expiration date, according to a picture of the license obtained by The Post.

Photos posted to X show who is purported to be frantic Blackstone employees stacking couches and other furniture in front of an office entrance during Tamura’s rampage.
