At approximately 9:00 PM, emergency vehicles and a life flight helicopter responded to an accident at the Discovery Bay Shopping Center. The accident was the result of an injury sustained by a man who put his hand through the window at Intero Real Estate. You can see how bad the injury must have been in this photo.
At 11:59 PM there was a loud noise, assumed to be an explosion of some kind, and was heard by residents in every corner of Discovery Bay. The source of that still has not been identified.
