Police say four people have been shot to death at a pharmacy on New York's Long Island during an apparent robbery.

Chief of Detectives Dominick Varrone says the dead included two employees and two customers.

Investigators believe that a single gunman was responsible for the shooting. The shooter fled the pharmacy, and no suspects were in custody.

Officials weren’t immediately releasing additional details about the shooting.
