Dashcam video of the shooting contradicted nearly everything police said happened the night McDonald died in October 2014. It showed McDonald walking away from police as he held a 4-inch knife, not lunging toward officers, as police had said.
Van Dyke jumped out of his vehicle and pulled his gun, firing at McDonald six seconds after arriving on the scene.
Van Dyke continued to fire, unloading every round from his gun in 15 seconds.
The video appears to show McDonald’s body getting hit by bullets even after he was on the ground. All 16 bullets struck McDonald, 17.
It took 400 days to release the dashcam video to the public. After the city’s objections, a judge ordered the release in November 2015.
Van Dyke became the first Chicago officer charged with first-degree murder since 1980.
He has pleaded not guilty to six counts of first-degree murder. If convicted, he could face up to life in prison.
Mayor Rahm Emanuel created the city task force in response to public outcry for accountability and transparency after the release of the McDonald shooting video in late November.
Tension in the city, which had built for years, had reached a fever pitch with protesters calling for Emanuel and other city leaders to step down.
Demonstrators were outraged not just about the content of the video, but that it took 13 months to release it.
On December 1, Emanuel announced he had asked police Superintendent Garry McCarthy to resign, and McCarthy complied.
To address the slew of systemic issues within the police department, the Police Accountability Task Force report recommended nearly 100 changes.
Emanuel has announced the implementation of nearly one-third of those recommendations, including replacing Independent Police Review Authority with an agency that has “more independence.”
The US Justice Department is also investigating the police department.
