"I heard one of my fellow employees say, 'Run, he's got a gun,' then I heard the little pop of the gun I guess, and we all ran and law enforcement took over," employee Allen Anthony Dowling said.
As Fiore was updating reporters on the situation, a short burst of gunfire was heard from the area of the facility. Fiore didn't say how many shots police fired, or whether the gunman fired shots.
Fiore said there was apparently a prior relationship between the gunman and one of the women he took hostage, though he didn't elaborate.
Police swarmed the area in the morning and evacuated employees. Television news footage showed officers crouched behind a vehicle behind the building's loading dock.
Schools in the area were put on a modified lockdown.
