Two people were killed and two others injured Tuesday when an employee opened fire on his fellow workers in a fire hydrant factory in Albertville, Alabama. City Police Chief Jamie Smith said that the shooting at the Mueller Co. plant began at 2.30 a.m., and the gunman fled in a car. He was later found dead in his vehicle. “The person was deceased from what appears to be a self-inflicted gunshot wound,” Smith told Al.com. The plant has produced millions of fire hydrants, making Albertville the “fire hydrant capital of the world.”
