BOSTON >> Chicago Mayor Rahm Emanuel has asked former Massachusetts Gov. Deval Patrick to join a police accountability task force after the fatal shooting of 17-year-old Laquan McDonald.

Patrick is a Chicago native who worked under President Bill Clinton as U.S. assistant attorney general for civil rights before being elected governor in 2006.

Patrick will serve as a senior adviser to the task force.

Emanuel also worked in the Clinton administration, and served as chief of staff to President Obama, a close friend of Patrick's.

The task force's recommendations are due by March 31, 2016.

Patrick, a Democrat, left the governor's office earlier this year, succeeded by Republican Charlie Baker, after eight years in the job.

McDonald was shot 16 times as he moved away from police in 2014. His death has sparked protests in Chicago.
