KNOXVILLE — A Knoxville man was arrested last night after police say he made threats of violence at the Knoxville Walmart.

On Monday, August 4, 2025, at 8:24 p.m., Knoxville Police Officers were dispatched to Walmart for a report of a potential threat. Officers along with Marion County Sheriff’s Deputies arrived as employees were evacuating the store. Officers met with store management where evidence was collected, store video was reviewed, and the store was searched.

During the investigation officers learned the suspect had discarded playing cards in the store with hand-written messages threatening violence. Officers were able to identify the suspect and vehicle using modern-day law enforcement technology after store video showed the suspect exiting the store, entering a vehicle, and subsequently leaving the area.

Using information gathered during the investigation, deputies went to 207 Cinder Ave. in Harvey, IA where they located the suspect and vehicle. Officers created and were issued a search warrant for the vehicle, home, and suspect. The search warrant was executed shortly after and more evidence was gathered.

As a result of the investigation, 44-year-old William David Kisling was arrested. Kisling is charged with Threat of Terrorism, a Class D felony and Possession of Drug Paraphernalia, a simple misdemeanor.

The Knoxville Police Department was assisted by the Marion County Sheriff’s Office, Knoxville Fire & Rescue, Marion County Emergency Management, and Walmart staff.
