Chicago Mayor Lori Lightfoot's administration Wednesday afternoon released thousands of pages of long-hidden records from the city's investigation of an alleged cover-up for Jason Van Dyke, the officer sent to prison for killing Laquan McDonald in 2014.

The records consist of reports from Inspector General Joseph Ferguson recommending discipline for 16 officers based on his office's 2016-2017 probe into the police department's handling of the shooting, recorded by a now-infamous dashcam video hidden from the public for more than a year by then-Mayor Rahm Emanuel's administration.

The release also includes scores of documents that accompanied Ferguson's reports, largely fulfilling a Lightfoot campaign promise to release "all the attachments and the evidence" for the reports.

The 16 officers investigated include 11 officers that Ferguson recommended for dismissal in the alleged cover-up, four other officers he recommended for discipline for failing to ensure their dashboard cameras were working properly that night, and a Bureau of Detectives lieutenant who left the department before Ferguson issued a scathing report about his role in CPD's investigation of the shooting.
