Three people are dead and five are wounded after a man armed with an assault rifle and a handgun opened fire at a St. Louis manufacturing plant.
Police Capt. Sam Dotson confirmed the number but did not have names or details about the victims.
The shooting began around 6:30 a.m. Thursday at Swiss-based ABB Group's plant in St. Louis. Police are going room by room inside the sprawling plant, searching for the shooter and additional victims.
Many of the 40 or 50 employees inside the plant at the time of the shooting hid on the rooftop, in boiler rooms and in closets.
