The suspect in today’s deadly shooting in Midtown Manhattan was a 27-year-old who lived in Las Vegas, Nevada, law enforcement officials told CNN.

He had no significant criminal background, officials told CNN.

The suspected gunman was born in Hawaii but later moved to Las Vegas. He had a concealed carry permit for a handgun as well as an expired private investigator license in Nevada, officials told CNN.

In his youth, he was a competitive football player, sources told CNN.

Police shared a photo of the alleged gunman walking into the building carrying a long gun.

The suspect was found dead in a stairwell in the building from what is believed to be a self-inflicted injury, according to sources.

Police have not publicly identified the suspect, who they say was the “lone suspect” in the shooting. Law enforcement backtracked the suspect to his car, which video shows him exiting alone, sources told CNN.

A shooting at a midtown Manhattan office building on Monday left at least three people dead, including an off-duty New York City police officer, sources told the Associated Press.

The suspect was identified as Shane Tamura, of Nevada, two people briefed on the investigation told the AP. Sources said he fatally shot himself.

Law enforcement officials located identification on Tamura’s body, including a concealed carry permit from Las Vegas, the people said. The people were not authorized to discuss details of an ongoing investigation and spoke to the AP on condition of anonymity.

The Fire Department of New York said emergency crews were called to the Park Avenue office building around 6:30 p.m. for a report of someone shot. The building houses some of the country’s top financial firms and the National Football League.

Jessica Chen told ABC News she was watching a presentation with dozens of other people on the second floor when she “heard multiple shots go off in quick succession from the first floor.”

She and others ran into a conference room and barricaded tables against the door.

“We were honestly really, really scared,” she said, adding that she texted her parents to tell them that she loves them.

Mayor Eric Adams said multiple people were injured. He posted a clip to social media urging people still inside the office building to stay put because police officers were conducting a floor-by-floor search. The Democrat said he’s headed to the hospital to speak with the family and loved ones of those involved.

Local TV footage showed lines of people evacuating the office building with their hands above their heads. The building includes offices of Blackstone and the consulate general of Ireland.

Some finance workers at an office building down the block were picking up dinner at a corner eatery when they heard a loud noise and saw people running.

“It was like a crowd panic,” said Anna Smith, who joined the workers pouring back into the finance office building. They remained there for about two hours before being told they could leave.

The building where the shooting happened is in a busy area of midtown, located a short walk north from Grand Central Terminal and about a block east of St. Patrick’s Cathedral.

The city’s emergency management alert system warned of traffic delays, road closures and disruptions to public transportation in the area.

Through late July, New York City is on pace to have its fewest murders and fewest people hurt by gunfire than any year in recent decades.

An NYPD officer was killed and multiple other people were injured in a shooting at an office skyscraper in midtown Manhattan Monday evening, according to law enforcement sources.

The shooting occurred in the lobby of 345 Park Avenue on East 52nd Street. The gunman, armed with an assault rifle, shot a police officer, multiple sources said. The police officer was rushed to the hospital, but later died.

At least four civilians were also struck by gunfire, several of whom were in critical condition, according to sources.

NYPD Commissioner Jessica Tisch said just before 8 p.m. that the shooter was “neutralized” and the scene had been contained.

The suspect was later identified as Shane Tamura. A motive for the shooting was also not clear.

Records indicate that multinational businesses with offices inside the building at that address include the National Football League, as well as financial firms Blackstone and KPMG.
