Deadly chaos in Manhattan as gunman storms skyscraper, leaves four dead PHOTO

A married 36-year-old NYPD officer and three others were killed on the evening of July 28 when a gunman opened fire inside a luxury high-rise in Midtown Manhattan, New York City, before taking his own life, authorities confirmed.

The shooter, identified as 27-year-old Shane Tamura from Las Vegas, entered the 44-story building — home to the headquarters of Blackstone and the NFL — around 6:30 p.m., armed with a rifle, according to police and law enforcement sources cited by The New York Post.

Tamura, who was reported to have a known history of mental illness, began his deadly assault immediately upon entering the building’s lobby. NYPD Commissioner Jessica Tisch said at a press briefing Monday evening that the first victim was Officer Didarul Islam, who was fatally shot at close range.

Tamura then shot and killed a woman who had attempted to hide behind a pillar as the gunman continued firing indiscriminately throughout the lobby of 345 Park Avenue.

According to police, Tamura next approached the elevator area and fatally shot a security guard who had sought cover behind a reception desk.

In what Commissioner Tisch described as a disturbing moment of apparent restraint, Tamura encountered a woman exiting an elevator but chose not to harm her.

The shooter then entered the elevator and traveled to the 33rd floor—where the offices of Rudin Management are located—and continued firing as he moved through the floor. He shot and killed one additional person before ultimately turning the weapon on himself and shooting himself in the chest.

A graphic photograph obtained by The Post showed Tamura lying motionless on the floor, apparently deceased.

One more man was also shot in the building’s lobby but survived his injuries, police said.

Authorities believe Tamura acted alone.

“His motive remains under investigation,” said Commissioner Tisch. “We’re continuing to examine why he may have chosen this specific location.”

Law enforcement sources indicated that Tamura worked as a security guard at a Las Vegas casino and failed to report for his scheduled shift Sunday morning, raising concerns.

Tamura was found to possess a valid concealed carry permit issued in Las Vegas, with an expiration date in 2027, according to a photo of the permit seen by The Post.

Separately, two people were arrested near the building around the time of the shooting, including one individual who shouted, “Free Palestine, I’m not the shooter,” in what appeared to be an unrelated protest.
