Witnesses to the deadly shooting at 345 Park Avenue were in disbelief when they saw gunman Shane Tamura open fire — and some were left barely controlling their panic.
“I was on the one block away, and I heard shots being fired and then a bunch of police, they came to neutralize it,” said 30-year-old Oleksandr Stupak, who was standing across from the skyscraper when the bullets started flying Monday evening.


“I went to the Citizen app, and it says active shooting. A lot of police started to come. I mean. [It’s ] crazy,” he told The Post.
Another man — who was apparently in the tower’s lobby when 27-year-old gunman Shane Tamura walked in and started firing — was left gasping for breath on a neighboring office building’s stoop as he called a loved one to tell them what happened.
“I was at work, and this guy came in with an assault rifle and started shooting. I was in the lobby at work,” the man said into the phone.
He buried his face in his hands as he gasped for breath, and had a bandage on his knee and on a hand as a police officer tended to him.
