KNOXVILLE, Iowa — One person is dead following an officer-involved shooting in Knoxville late Thursday night.

Officers from the Knoxville Police Department were called to the 300 block of S. Roche St. around 11:10 p.m. on a report of a domestic dispute, according to a news release from Knoxville Chief of Police Aaron Fuller. When they arrived, they found a man assaulting a woman.

An officer fired his weapon during the incident, striking the man. Medical aid was provided to the injured man immediately by the officers, and the Knoxville Fire Department was called to the scene. The man was transported to a Des Moines hospital by ambulance, but died from his injuries at the hospital.

Chief Fuller said the female who was assaulted was transported to a local hospital for treatment, and she has been released. No officers were injured in the incident.

Before officers arrived, a gas line at the home was ruptured, prompting officials to evacuate the immediate area as a safety precaution. Once Alliant Energy capped the gas line, residents in the area were allowed to return to their homes.

“The dedicated Officers of the Knoxville Police Department strive to provide professional law enforcement services for our community. This includes transparency when incidents like last night occur. I requested the Iowa Division of Criminal Investigation (DCI) to conduct an independent investigation into this officer involved shooting. The investigation will take several weeks to complete. The DCI will forward their findings to the Marion County Attorney and Iowa Office of the Attorney General for review,” stated Chief Fuller.

The officers involved in the event have been placed on critical incident leave, which Chief Fuller said is standard practice. Their names and the name of the deceased aren’t being released at this time.
