The surveillance video, which was recorded by a camera across the street from the park, shows what appears to be a quiet gathering in the moments before the shooting. As the bullets began flying, people ran for cover, with some getting in nearby cars and driving off.

Investigators have not said what may have prompted the shooting. Anyone who may have been in the area at the time of the shooting or who can identify any of the people or vehicles seen in the video is asked to contact the Reading police by calling 610-655-6116.
