CHICAGO (AP) — Mayor Rahm Emanuel has fired Chicago's police superintendent and named a task force to study police accountability in the aftermath of the release of a 2014 video showing a white police officer shooting a black teenager 16 times. Emanuel defended the city's handling of the matter, saying the timing of the video's release — more than a year after the shooting — had nothing to do with his 2015 re-election campaign.
Here's a look at key moments in the case and the fallout once the video was released.
OCT. 20: Officer Jason Van Dyke responds to a call about a teenager breaking into cars and stealing radios. He shoots 17-year-old Laquan McDonald, whom authorities say is armed with a knife, 16 times, killing him.
FEB. 27: Lawyers for McDonald's family approach City Hall about a possible settlement without filing a lawsuit, according to Emanuel. This was three days after the mayor failed to win a majority of votes in his re-election bid, forcing him into the city's first mayoral runoff.
APRIL 7: Emanuel defeats Cook County Commissioner Jesus "Chuy" Garcia to win a second term. The mayor made a special appeal to black voters during his campaign.
APRIL 8: Attorneys for the city and the McDonald family agree to settle for $5 million after previously meeting twice.
APRIL 15: The Chicago City Council votes to approve the $5 million settlement.
MAY 26: A freelance journalist files a Freedom of Information Act request for squad-car video of the shooting. After the city denies the request, citing an ongoing investigation, he files a lawsuit.
NOV. 19: A Cook County judge orders Chicago officials to release the video on or before Nov. 25.
NOV. 24: Cook County State's Attorney Anita Alvarez announces she is charging Van Dyke with first-degree murder. Hours later, Chicago police release the video, sparking several days of protests.
NOV. 29: The University of Chicago announces it is canceling all classes and activities on Nov. 30 because of a threat mentioning the quad and Monday morning.
NOV. 30: Chicago resident Jabari R. Dean is charged in a federal complaint with transmitting a threat in interstate commerce. Prosecutors say the 21-year-old black man threatened on a social media website to kill 16 white male students or staff at the University of Chicago, and was motivated by McDonald's death.
DEC. 1: Emanuel fires Chicago police Superintendent Garry McCarthy and names a five-member task force to make recommendations on improving police accountability. Chief of Detectives John Escalante is named interim chief.
