Chicago officials release videos of police shooting that killed 13-year-old Adam Toledo

A police oversight agency on Thursday released video of a Chicago police officer fatally shooting 13-year-old Adam Toledo last month. Mayor Lori Lightfoot called for calm as the city braces for protests throughout the night.

Video shows an officer exiting his vehicle and chasing Toledo, who is running down an alley. When the officer catches up to the teen, he orders him to raise his hands and yells, "Drop it, drop it." The officer fires a single shot to Toledo's chest as the teen raises his hands. The teen drops to the ground and the officer rushes to administer aid and calls for backup. Police have said a semi-automatic pistol was recovered a few feet away. Lightfoot on Thursday said there was "no evidence" the teen fired the weapon before he was shot.
