Chicago chief of detectives retires

CHICAGO (AP) - A high-ranking Chicago police officer is retiring in the wake of the release of a graphic dashcam video showing the fatal shooting of a black teenager by a white police officer in 2014.

Department officials say Constantine "Dean" Andrews retired Monday, effective immediately. He was chief of detectives.

He tells The Chicago Tribune he informed interim Superintendent John Escalante a day earlier.

Andrews says with everything changing and a temporary superintendent, he thought it would be best for the city and department.

He adds that neither a recently announced U.S. Department of Justice investigation nor a high-profile case involving former Mayor Richard Daley's nephew impacted his decision.

Andrews was deputy chief of detectives in 2011 when authorities reinvestigated the 2004 death of David Koschman, who was in a fight with Daley's nephew and died after he fell and hit his head.
