UPDATE: 4 Killed In NYC Shooting Including NYPD Officer, Suspect Identified

More details have emerged of the shooting that occurred in a Midtown Manhattan office building.

The New York Police Department has reported that Shane Tamura, 27, opened fire inside a Manhattan skyscraper on Monday evening, killing four people, including an NYPD officer.

The building where the shooting took place is the headquarters for the NFL and investment firm Blackstone.

ABC News provided an update on the shooting:

A 27-year-old man wearing body armor and carrying a high-powered M4 rifle shot and killed four people, including an off-duty police officer working security in a Midtown Manhattan office building, officials said during a press conference Monday evening.

A fifth victim was left critically injured in the shooting, officials said.

The incident occurred just before 6:30 p.m. in a building located at 345 Park Ave. and 52nd Street, which contains the headquarters for the investment company Blackstone and the National Football League, sources told ABC News.

It is unclear if those companies, or any company in the building, were tied to the shooting.

After apparently barricading himself on the 33rd floor, the suspect, who was identified as Las Vegas resident Shane Devon Tamura, was found dead from what is believed to be a self-inflicted gunshot wound, according to New York Police Department Commissioner Jessica Tisch.

NBC News reported on what is known of Shane Tamura:

Law enforcement officials said the violence was carried out by a lone gunman, who died from a self-inflicted gunshot wound.

The suspected shooter has been identified as Shane Devon Tamura, 27, of Las Vegas, according to four senior law enforcement officials.

In a photo three law enforcement officials shared with NBC News, the suspected gunman is seen walking into the midtown Manhattan building wearing dark clothes and sunglasses and carrying what appears to be a large firearm.

A motive has not been determined.

Caleb Clarke, a former classmate and high school football teammate, said that Tamura “was the biggest goofball in the world, just a ton of energy, class clown.” The two played together in California until Tamura transferred from Santa Clarita High School to Grenada Hills High School in 2015, just before their senior year.

Clarke said that in recent years, he and Tamura kept up only through social media, where Tamura shared that he had been working at a casino in Las Vegas.

Clarke didn’t recall Tamura ever being a troublemaker in school. “You never would have thought violence was something you’d associate with him,” Clarke said. “You know, he could make a joke about people, but that’s just typical. Shane was a jokester. Everything he said was a joke. He had a ton of energy.”

He added that it seemed as if Tamura was destined for greatness as an athlete.“I feel like it was definitely on the table for him,” Clarke said. “I don’t think he walked around to be like, ‘Oh, I’ll have NFL games one day.’ I think it was more of everybody just telling him how great he was … how special he was.”

The building:

Midtown Manhattan’s 345 Park Ave. is the headquarters of the investment firm Blackstone.

The building also hosts the headquarters of the NFL and a Bank of America branch, as well as offices belonging to KPMG.
