The Midtown office shooter successfully applied for a gun permit in 2022 – and held onto the permit after he told Las Vegas authorities he was having suicidal thoughts, according to law enforcement sources.

Shane Tamura was granted the permit in June 2022 and notified police sometime after that he was suffering from a mental health crisis, sources said.

But suicidal ideations are not enough to revoke a permit, according to sources.

How the shooting unfolded

• Reports of the shooting at 345 Park Ave. start coming in around 6:28 p.m.
• Shane Tamura, 27, is seen getting out of a black BMW between 51st and 52nd streets with an M4 rifle.
• He enters the lobby and turns right, where he shoots police officer Didarul Islam, 36, dead.
• Tamura guns down a woman cowering behind a pillar in the lobby, sprays more bullets and walks toward the elevator bank — where he shoots dead a security guard crouching at his desk.
• One more man reports being shot and injured in the lobby. He was in critical but stable condition.
• The gunman allows 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 is shot and killed on that floor before Tamura shoots himself in the chest.
• It’s unclear how long the mayhem lasted. Police Commissioner Jessica Tisch posted on X at 7:52 p.m.: “The scene has been contained and the lone shooter has been neutralized.”

He then had another mental health contact in Las Vegas in 2024, sources said.

Authorities said Monday that Tamura, who killed four people, had a history of mental health problems.
