A Springfield officer is on paid leave after shooting and killing a man. Officer Grant Story said the initial call was for a domestic assault.

When officers arrived, a woman said the man beat her in the parking lot. Story said the man ran into an apartment and officers followed. He said the officer shot the man because he answered the door and threatened them with a knife.

"Anytime you have an officer involved shooting it certainly a traumatic event," he said. "No officer wants to take that sort of force to protect himself but from time to time that sort of force is required."             

The officer was not injured. The woman went to the hospital for cuts to her face.
