A two-year-old boy was fatally shot in Chicago Tuesday in what police suspect was a gang hit amid ongoing gun violence in the city that has drawn attention from President Donald Trump.

McDonald, a 17-year-old Chicago teen, was shot 16 times in 2014 by officer Jason Van Dyke. McDonald's death lit a long simmering fire within Chicago that led to protests, calls for Emanuel's resignation, the termination of former superintendent Garry McCarthy, and a Justice Department probe.

Witnesses say they overheard Hampton and the man exchange a few words before he stabbed her multiple times, slitting her neck and torso.
