UPDATE: Suspect arrested in fatal shooting at Long Island grocery store

A four-hour manhunt came to an end Tuesday when police arrested a suspect in a shooting that killed one and wounded two others at a grocery store in Long Island, New York, according to reports.

The suspect has been identified as 31-year-old Gabriel DeWitt Wilson, according to NBC4 in New York, citing a statement by the Nassau County Police Department, which confirmed the man had been taken into custody.

Wilson was arrested about 3:15 p.m. at an apartment building about 2 miles from the store, Nassau County Police Commissioner Patrick Ryder said.

The gunfire erupted about 11:15 a.m. at a Stop & Shop supermarket in West Hempstead, reports said.

A man wearing a black baseball hat and a black sweatshirt walked into an upstairs office area of the store and opened fire with a small handgun, according to authorities.

The three victims were reportedly employees, but their names have not been released. The person who died was a 49-year-old manager at the store, NBC4 reported.

Reports said both survivors were conscious and alert at the hospital, although there was no word on the extent of their injuries or whether they were targeted because of a grievance.

Hundreds of people were inside the store shopping at the time and ran outside when they heard gunshots.

One witness said she counted six shots.

“They told us to just run and get out, and that’s what we did,” shopper Laura Catanese told News 12 Long Island.

After the shooting, the gunman was believed to have jumped on a city bus and fled the scene.

Dozens of police and emergency personnel quickly moved in.

The suspect remained at large for more than four hours after the shooting as police fanned out around the city to find him.

Nearby schools were placed on lockdown as a precaution, and residents were warned to remain indoors due to the developing situation.

The motive and circumstances of the shooting remain unclear, although police said the suspect worked as a shopping cart wrangler at the store and went to the offices immediately after arriving for work Tuesday.

Wilson has a criminal record and had been taken into custody previously in Nassau County for a mental health evaluation, Ryder said, according to The Associated Press.

Wilson was involved in a shooting in Baltimore seven years to the day before Tuesday’s supermarket shooting, records show. According to police, Wilson and another man fired shots at each other and were hospitalized with lower body wounds. Attempted murder charges against Wilson in that case were later dropped, records show.
