Micalla Rettinger, 25, was fatally shot in the early morning hours of April 28, 2019, while driving southbound on U.S. Highway 218 over the Cedar River near George Wyth State Park in Waterloo, Iowa. She was driving a Jeep with her boyfriend in the passenger seat, another friend and a dog in the back. Around 2:30 a.m. a single bullet entered the driver’s side window, struck Micalla in the neck and continued to hit her boyfriend in the face. Micalla pulled the vehicle to an off-ramp but succumbed at the scene; the boyfriend survived and was treated at a hospital. The other passenger and the dog were uninjured.

Waterloo police originally responded to a report of a possible motor vehicle accident and opened a homicide investigation after finding evidence of a shooting. Investigators have considered possibilities including a hunting accident because of the wooded area near the highway but have not released definitive findings; they have mentioned having an idea of the firearm caliber without giving specifics. State and federal authorities have assisted, no arrests or publicly identified suspects have been announced, and Cedar Valley Crime Stoppers has offered a substantial reward.

Micalla was a former University of Northern Iowa softball player. Does anyone have information about that stretch of U.S. Highway 218 or the area near George Wyth State Park on the night of April 28, 2019?
