(CNN) -- One person was killed and another was wounded after a man walked into a suburban New York business and opened fire Wednesday, local officials said.

The incident took place at Savenergy in East Garden City on Long Island.

Detective Michael Bitsko of the Nassau County Police Department told CNN the man is a former employee at the light fixture manufacturer.

The man fled the scene and police said they think he might have been headed west.

A local mall went on lock down at the request of police after the shooting was reported, shortly after 10 a.m.
