Chicago city officials have released video footage of an unarmed, 18-year-old black youth, Paul O'Neal, being gunned by police last month prompting the attorney for the victim's family to characterize the deadly act as a case of "cold-blooded murder." Paul O'Neal died of gunshot wounds he suffered in the South Shore neighborhood on July 28, at least one of them to the back, reportedly.

Reports are police chased and opened fire on O'Neal after they encountered him in a stolen Jaguar near where he took his last breath.

The O'Neal family has already filed a federal lawsuit against the officers involved in the shooting.
