He then fled from the auto, leading cops on a foot chase into a homeowner's backyard.
The videos were taken July 28 from police body cameras and dashboard cameras, with some of the images jumbled as the officers ran, and the sound punctuated by gunfire and the officers' own shouting and labored breathing.
O'Neal abandons the vehicle soon after the multiple shots from police and runs onto a neighboring residential property as police give chase. The teen, police learned, was not armed.
Warning the video contains graphic language and strong content. He said that he also was "concerned" by some of the things he saw in the videos-which show police officers shooting Paul O'Neal, . The head of that agency called the video "shocking and disturbing". Family spokesman Ja'Mal Green said O'Neal's mother broke down. "Once the gunshots started, they immediately left the room ... crying, breaking down". It is one of the most horrific things that I have seen, aside from being in a movie. Many viewed his appointment as a bid to stem a wave of violence in Chicago and to clean up a troubled department.
The latest recording catches the stolen vehicle being pursued by officers as it blows through a stop sign.
O'Neal was shot in the back, the Associated Press reports, and the fatal shooting was not captured on video because the body cam of the officer who fired the fatal shot was not operating at the time, authorities said.
Oppenheimer alleged the non-operating body camera was part of a police effort to cover up what he called a "cold-blooded murder". He also asks another officer, "Who was shooting in the alley".
"It is unbelievable to think that this new technology, the way we are in this world, simply didn't work".
He said he relieved officers of duty last week because of those concerns. It is believed police mistook gunfire by other officers as attacks on law enforcement officials made by the fleeing suspect.
Three police officers have been suspended and O'Neal's family has filed a federal civil rights lawsuit against the officers, accusing them of firing at the teen "without lawful justification or excuse". The officer who shot McDonald, Jason Van Dyke, is charged with murder.
Chicago police superintendent Eddie Johnson promised that the officers will be held accountable if they are found to have acted inappropriately. Because the investigation into the incident is ongoing, police are prohibited from commenting on which policy was violated.
"That's why policemen, their professional acumen builds over time", he said, adding: "And it's easy for us to sit back after the fact when we have time, we're at home, in our offices or just look at the video when we have hours and we can go back and dissect it", Johnson said.
As the Justice Department investigates the city's policing practices, Mayor Emanuel and Johnson has attempted to reform the department.
"There's no need to say anything", a young woman said of the superintendent, who eventually gave up and returned to headquarters without uttering a word.
