City hires two outside law firms for DOJ investigation

CHICAGO (WLS) -- The city of Chicago is looking to outside firms to help deal with the Justice Department investigation into the Chicago Police Department.

The investigation was launched after a court forced the city to release dash cam video showing the fatal shooting of 17-year-old Laquan McDonald.

Crain's reported that Wilmer Cutler Pickering Hale & Dorr will be the lead firm, and will be supported by the Chicago office of Taft Stettinius & Hollister. Wilmer Hale is also representing the city of Baltimore in their Justice Department investigation.

The investigation into the police department is expected to be lengthy and expensive; the firms could charge the city up to $1,200 an hour for some services.
