Van Dyke shot 17-year-old Laquan McDonald 16 times in October 2014.

The new indictment brings to 23 the number of felony counts against Van Dyke. He faces six counts of first-degree murder, one count of official misconduct and now 16 aggravated battery counts.

Van Dyke was charged in 2015 at the same time the city — on a judge's orders — released video of the shooting.
