Four people including the gunman have been killed in a series of shootings in the US state of Kansas, police say.
Fourteen people were also injured, 10 critically, in the shootings at a lawnmower factory in Hesston and nearby.
The suspected attacker was an employee at the factory, police said. He was later shot dead.
The shooting was not believed to have any link to terrorism, County Sheriff T Walton said.
The four deaths all occurred in the attack at the Excel Industries factory.
Factory employee Martin Espinoza described how the gunman, a colleague who he said usually had a calm demeanour, attempted to shoot him.
The gunman pointed his gun at Mr Espinoza and pulled the trigger, but the weapon was empty. Mr Espinoza then ran away as the gunman took out a second gun.
"I looked right at him and he looked right at me," Mr Espinoza said.
Another witness described scenes of panic.
"All I know is I'm seeing people running and so I'm assuming fire, and so I take a few steps and I hear pop, pop and I'm thinking just some paint cans or something going up, and more people running and all of a sudden, pop, pop, pop, pop, pop, pop, pop, pop, pop and I'm going, ahh, I start running too," said one man.
