Shooting at Long Island Grocery Store Leaves 1 Dead, 2 Wounded

A gunman walked into the manager’s office of a Stop & Shop grocery store on Long Island on Tuesday and opened fire, killing one person and wounding two others before fleeing, the police said.

The police said they were searching for a man wanted in connection with the shooting, and identified him as Gabriel DeWitt Wilson, 30, of Long Beach and Hempstead, N.Y.

Commissioner Patrick J. Ryder of the Nassau County Police Department said at a news conference that it was not yet clear what led to the shooting, which took place at a Stop & Shop in West Hempstead, N.Y. He said that Mr. Wilson was either a current or former employee of the grocery store, and that the police were investigating whether the shooting was connected to his employment there.

The police did not release the name of the man who was killed, but Commissioner Ryder said he was a Stop & Shop employee. The two other victims were at the hospital, the police said.

Hundreds of people were inside the store when the shooting took place around 11:20 a.m., Commissioner Ryder said. Local schools were placed on lockdown and neighbors advised to stay indoors as the police searched the area nearby for the gunman, who they said left the scene carrying a small handgun.

The shooting on Long Island on Tuesday came as the nation was still reeling from a string of other mass shootings, including one at a FedEx facility in Indianapolis last week that left eight people dead.

Stop & Shop, which is based in Quincy, Mass., is a chain of 400 neighborhood grocery stores throughout Massachusetts, Connecticut, Rhode Island, New York and New Jersey. The company did not immediately respond to an inquiry about the shooting.
