Police said there are four suspects involved in the crime, though the driver of their car cannot be seen in the video because he never got out of the car. Police said the motive for the crime was carjacking, pure and simple.

"You saw three suspects exit the car," said Chief Brendan Deenihan. "We believe at least two of them discharged their weapons."

Police said Williams was making his regular visit to a Morgan Park popcorn shop when the father of four was murdered.

"Think about your father. What if this was your father?" said community activist Andrew Holmes.
