The Pottawatomie County Sheriff's Office has wrapped its investigation of Wednesday's fatal shooting near Pink and believe it was a case of self-defense.

Sheriff Mike Booth identified the shooting victim as Richard Kolb, 40. He said Kolb was shot in the chest.

After a physical altercation at a man's home on Rolling Hills Drive, the victim left and came back with a gun and allegedly shot at a vehicle at the residence, Booth said.

The suspect then retrieved a weapon as the victim attempted to enter the house and a shot was fired, resulting in Kolb's death, Booth said.

After the investigation, the sheriff's office determined the suspect was acting in self defense, Booth said.

“The evidence shows the victim fired several shots into a parked car and attempted to enter the house,” Booth said. “The suspect was protecting himself and his family when he fired the shot.”

Booth said the evidence, along with witness statements of what happened, determined the suspect was acting in self defense, Booth said.

The suspect voluntarily went to the sheriff's office for questioning and was released, Booth said.

The evidence was turned over to the District Attorney's office for final determination, Booth said.
