UPDATE- Police investigating multiple homicides in Muscatine

The Muscatine Police Department is actively investigating a series of homicides that occurred Monday, June 1, 2026, at multiple locations within the city.

At approximately 12:12 p.m., MUSCOM received a report of a shooting at 210 Park Avenue. Police officers and emergency medical personnel were dispatched immediately. Upon entering the residence, officers located four individuals who had sustained gunshot wounds. All four victims were pronounced deceased at the scene.

The suspect, identified as Ryan Willis McFarland, 52, of Muscatine, had left the residence prior to officers’ arrival. Law enforcement located McFarland a short time later on the Riverfront Trail near the pedestrian bridge. He was found with a self‑inflicted gunshot wound. Officers and EMS personnel provided medical aid, but he was pronounced deceased at the scene.

As the investigation progressed, detectives developed information indicating there may be additional victims. Officers subsequently located an adult male deceased from an apparent gunshot wound inside a residence at 1509 Mill Street. A further search led officers to a business at 808 Grandview Avenue, where another adult male was found deceased from an apparent gunshot wound.

Preliminary findings indicate the shootings stemmed from a domestic‑related dispute. All victims are believed to be family members of the deceased suspect.

The Muscatine Police Department is receiving assistance from the Muscatine Fire Department, the Muscatine County Sheriff’s Office, the Iowa State Patrol, and the Iowa Division of Criminal Investigation.

The investigation remains active and ongoing. Detectives continue to process multiple crime scenes and conduct interviews.
