Three people were shot, one fatally, at a Long Island supermarket Tuesday, according to local authorities. 

The shooting took place at a West Hempstead Stop & Shop on Cherry Valley Road, where law enforcement was called around 11:15 a.m., according to the Nassau County Police Department. 

The county’s Police Commissioner Patrick Ryder said the person killed was a 49-year-old male employee. The two other victims are “conscious and alert” at local hospitals and speaking to law enforcement.

Ryder identified a former employee, 31-year-old Gabriel DeWitt Wilson, as a person of interest in the shooting that took place in an upstairs manager’s office, away from the shopping floor. The suspect had a small handgun. 

Shortly after 3 p.m., Nassau County Executive Laura Curran tweeted that suspect taken into custody.

“The #NassauCountyPD can confirm that the subject has been apprehended and taken into custody,” NCPD wrote on Twitter. “Our thoughts are with those who were killed and injured today.”

Ryder told reporters that there were “a couple hundred” people in the store at the time of the shooting.
