Gunman kills 4, including police officer, then shoots himself at Manhattan office building
The police officer who died was a Bangladeshi immigrant with a pregnant wife and two sons

A man carrying a rifle killed four people at a New York City office tower on Monday, including an off-duty New York City police officer, and wounded a fifth before taking his own life, officials said.
The officer who was killed was Didarul Islam, 36, an immigrant from Bangladesh who had served as a police officer for 3½ years, New York Police Commissioner Jessica Tisch said at a news conference.
“He was doing the job that we asked him to do. He put himself in harm’s way. He made the ultimate sacrifice,” Tisch said. “He died as he lived. A hero.”
Police identified the gunman as Shane Tamura, of Las Vegas, and said he killed himself. He had a “documented mental health history”, but the motive was still unknown, Tisch said.
“We are working to understand why he targeted this particular location,” Tisch said of 345 Park Avenue, a commercial office building whose tenants include the NFL and Rudin Management, as well as finance companies KPMG and Blackstone.

One man was seriously injured and remains in critical condition, Mayor Eric Adams said. Four others were slightly injured attempting to flee the scene. Adams said officials were still “unravelling” what took place.
