One officer was treated for injuries to his eye and face caused by broken glass. Prosecutors said it was unclear from video whether the boy knew it was a police vehicle when he fired, but the investigation is ongoing. Prosecutors said Monday that almost at the same time the officers turned the red and blue lights on, a shot came through the back passenger window and ricocheted around the car. They saw two youths, Siderio and an unnamed 17-year-old, and maneuvered the car around the block and next to them to initiate a stop. Police said the four plainclothes officers were in an unmarked car on the night of March 1, looking for a teenager they wanted to interview related to a firearm investigation. Krasner called the entire foot-chase 'tactically unsound' and said the video was 'disturbing to watch,' though when pressed he refused to characterize the shooting beyond saying it was clear to him there was evidence to support a first-degree murder charge.
