The officer, Jason Van Dyke, was being processed at Chicago's main criminal courthouse and appeared at a bond hearing early Tuesday afternoon.
Judge Donald Panarese Jr. ordered Van Dyke held without bail until the judge can view dashcam video of the incident, the Chicago Tribune reported.
On Wednesday, the city will release the dashboard camera video that it says shows the officer shooting and killing Laquan McDonald, who was 17.
Van Dyke fired 16 rounds at McDonald in 14 seconds, just six seconds after exiting his squad car, Cook County prosecutors said in court, according to the Chicago Tribune. McDonald was reportedly walking away from Van Dyke, and his autopsy showed two shots in the back, among 14 other entrace wounds.

Van Dyke has said through his lawyer and the police union that he felt under threat from McDonald.
