Police confirmed that the only person who fired a weapon during the chase was an officer, "whose gunfire unintentionally struck Officer Rivera."

Chicago police officials say an officer killed this week was accidentally shot and killed by her partner after they encountered someone with a rifle when they chased a suspect into an apartment.

Officer Krystal Rivera of the Chicago PD died after being unintentionally shot by another officer amidst a confrontation with a suspect. Her death has deeply affected the city and her colleagues.
