Chicago Police Supt. Larry Snelling on Saturday cautioned against a rush to judgment, after police confirmed Officer Krystal Rivera was accidentally shot and killed by a fellow officer Thursday night during a chase in the Chatham neighborhood.

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.

Krystal Rivera, the Chicago police officer shot and killed in Chatham, was a loving mother, friend, and devoted police officer who cared deeply about protecting the community.
