The attack unfolded shortly after 11 a.m. in the second-floor manager's office at a Stop & Shop store in West Hempstead, said Nassau County Police Commissioner Patrick Ryder.
The suspect, who was dressed in all black, was identified by police as Gabriel DeWitt Wilson, 31, of Hempstead and Long Beach, New York. He is either a current or former employee of the Stop & Shop, Ryder said.
"He did have a small handgun," Ryder said. "We don't know the reason for the shooting."
Witnesses interviewed on local media reported hearing at least six shots. Some witnesses reported to news crews that the suspect may have jumped onto a bus to escape, but police could not confirm that account.
