CHICAGO (AP) – A Chicago Police spokesman says the city’s Inspector General’s office has delivered a report on the fatal 2014 police shooting of black teenager Laquan McDonald.

Spokesman Anthony Guglielmi says the department is reviewing the report and will respond. He says he does not know how long the review will take.

A spokeswoman for Inspector General Joseph Ferguson declined to comment.

News of the report comes as the department announced the retirement Deputy Chief David McNaughton, who determined the shooting by Officer Jason Van Dyke complied with department policy.

Those findings were harshly criticized when the video was released in November that showed McDonald didn’t threaten officers. Van Dyke has been charged with first-degree murder.

The CPD’s announcement about McNaughton’s retirement doesn’t mention the McDonald case.
