Waterloo police have made an arrest in a two-week-old murder case. Officials have charged 18-year-old Dorondis Cooper with first-degree murder in the shooting death of Thyanna Parsons. Police say bullets were sprayed at partiers outside an east-side Waterloo home on October 10th, hitting the house and a car parked nearby. Parsons was inside the home and was struck by one of the bullets. She later died. Cooper was injured in the shooting, but authorities haven’t indicated how he was hurt. Cooper is being held in the Black Hawk County Jail on one million dollars bond. Three other men — two brothers and a cousin — are facing lesser charges in connection with the shooting.
