WATERLOO, Iowa (KWWL) – It's likely one of the biggest mysteries of 2019: who shot and killed Micalla Rettinger?
Rettinger was driving southbound on Highway 218 between Waterloo and Cedar Falls on April 28. A bullet came through the driver's side window as her vehicle crossed Brinker Lake and the Cedar River. That bullet would kill her and injure her friend, Adam Kimball.
Before she died, she was able to stop the car at the Greenhill exit.
Just days after, Rettinger's parents would make a tearful plea for the person who fired the shot to come forward. That person has still yet to say anything.
Waterloo Police are still pursuing the investigation. They are working closely with authorities at the state and federal level, including the FBI.
Cedar Valley Crime Stoppers and Waterloo Police are offering a $58,000 reward for any information. If you’d like to make a pledge to the reward, or have information, you can call the Waterloo Police Department at 319-291-4340, ext. 7, or Cedar Valley Crime Stoppers at 855-300-TIPS (8477).
