NYPD Commissioner Jessica Tisch laid out a timeline of how Shane Tamura carried out his heinous killing spree on a Midtown skyscraper early Monday evening — gunning down four people in under an hour in the targeted attack.

Here’s a full breakdown of the harrowing events:

Tamura, a Las Vegas resident, failed to show up to his job as a casino security guard on Sunday and traveled across the country to reach New York City shortly before his deadly rampage.

His car was spotted passing through Colorado on Saturday, Nebraska and Iowa on Sunday and Columbia, New Jersey at 4:24 p.m. Monday. He drove into Manhattan “shortly thereafter,” Tisch said.

Reports of the shooting at 345 Park Avenue started coming in at around 6:28 p.m.

Tamura, 27, was seen on surveillance footage getting out of a double-parked black BMW between 51st and 52nd Street, with an M4 rifle.

He then walks towards the skyscraper, enters the lobby and turns right, where he shot police officer Didarul Islam, 36, dead.

Tamura then shot a woman cowering behind a pillar in the lobby, as he sprayed more bullets and walked toward the elevator bank — where he also fired at a security guard crouching at his desk.

One more man reported being shot and injured in the lobby. He was in critical but stable condition.

The gunman allowed a woman to walk out of the elevators unharmed, before heading up to the 33rd floor, where building owner Rudin Properties’ offices are located, “and begins to walk the floor, firing as he traveled.”

One woman was found shot and killed on that floor.

Here is the latest on the NYC mass shooting:

“He then proceeds down a hallway and shoots himself in the chest,” ending his rampage.

It’s unclear exactly how long the mayhem lasted.

The shooter’s body was found by officers between 7:15 and 7:30 p.m., according to police sources.

Tisch posted on X at 7:52 p.m.: “The scene has been contained and the lone shooter has been neutralized.”
