HESSTON, Kan. (AP): The Latest on the attack at a central Kansas factory (all times local):

7:30 a.m.

A sheriff says the police officer who shot and killed a gunman who was attacking the central Kansas factory where he worked is a “tremendous hero.”

Harvey County Sheriff T. Walton said Friday that had the Hesston police officer not killed the man during the Thursday evening attack at the Excel Industries lawnmower parts plant, it “would be a whole lot more tragic.”

He says there were still 200 or 300 other people in the factory and that “the shooter wasn’t done by any means.”

Walton didn’t identify the officer or the attacker.

Authorities say the attacker shot and wounded three people before storming into the factory, where he shot 15 others, killing three of them, before the officer killed him.

7 a.m.

Authorities say a man who opened fire on the central Kansas factory where he worked was served with a protection from abuse order shortly before the attack.

Harvey County Sheriff T. Walton said Friday that the sheriff’s office served the suspect with the order at around 3:30 p.m. Thursday and that he thinks it was likely what triggered the attack, which began about 90 minutes later.

He says such orders are typically served “because there’s some type of violence in a relationship,” but he declined to specify the nature of the relationship in question or to disclose the attacker’s name.

Pickett says the suspect shot two people while driving to the Excel Industries plant in Hesston where he worked and shot another person in the parking lot before going inside. He says the man shot 15 others in the lawnmower parts factory, killing three of them, before a Hesston police officer shot him dead.
