Prosecutors allege the men falsely claimed in their reports that McDonald had battered, assaulted and attacked white police officer Jason Van Dyke, who shot McDonald 16 times in 2014.

A jury last month convicted Van Dyke of second-degree murder and 16 counts of aggravated battery.

Defense attorneys had attacked the prosecution’s case as a sham and asked that the case be dismissed.
