HESSTON, Kan.: A sheriff said four people, including a gunman, are dead after a series of shootings in south-central Kansas.

Harvey County Sheriff T. Walton said at a news conference Thursday night that all the dead were shot inside Excel Industries, which makes lawn mower products. He said law enforcement killed the suspect, who was an employee.

Walton said 14 people were injured in attacks that took place at four locations.

An employee of Excel said he was in the plant when he heard people yelling to get out of the building. Martin Espinoza told the Associated Press he heard a popping sound and then saw the shooter, who was a co-worker. Espinoza said the shooter pointed a gun at him and pulled the trigger, but the gun was empty. He said at that point, the shooter got a different gun and Martin took off running.
