(Muscatine, Iowa) – A woman was shot and killed and the suspected shooter suffered what authorities say was a self-inflicted gunshot wound Monday, in southeast Iowa. According to the Muscatine Police Department, the Muscatine Communications Center received multiple shots-fired reports coming from inside the Muscatine Hy-Vee Store, at around 2-p.m., Monday. Police and Medics responded immediately and located the victim, 37-year-old Kalista Rae Hallberg, of Letts (IA), who had suffered from multiple gunshot wounds. She died at the scene.

The suspect, Ian Antonio Hernandez, of Davenport, fled the scene in a mini-van. The vehicle was located at the intersection of Highways 61 & 38. Officers found Hernandez inside the vehicle. Officers rendered medical aid to Hernandez until Muscatine Fire Dept. personnel arrived on the scene. Hernandez was transported to a local hospital and later flown to the University of Iowa Hospital, where he was in critical condition at last report. Authorities say a preliminary investigation determined the shooting originated from an ongoing domestic dispute between Hallberg and Hernandez.

Muscatine Mayor Brad Bark shared a statement on social media that said, in-part:

“This act of violence, perpetrated by an individual who does not call Muscatine home, is a shameful affront to the values of our community. It has wounded the spirit of our close-knit community, and I explicitly condemn it. No one should fear for their safety in Muscatine, a place we call home—a place where we shop, gather, and build our lives. This tragedy reminds us how precious and fragile our sense of security is, and it strengthens our resolve to ensure such heartbreak does not define us.”
