On Saturday morning, March 25, at around 4:40am, Contra Costa CHP was advised of a hit and run traffic collision on northbound I-680 south of Monument Blvd. Upon CHP and emergency personnel arrival it was determined a pedestrian (19-year-old male from Antioch) was struck by three vehicles. The first vehicle to strike the pedestrian left the scene.

The first vehicle to strike the pedestrian was described as possibly being a white Acura Integra. The pedestrian was pronounced deceased at the scene of the collision. On Monday, the victim was identified by the Contra Costa County Coroner as Dyshon Douglas.

In the initial investigation, it appears that the pedestrian was standing in the lanes of northbound I-680 just south of Monument Blvd. It appears as though a white colored sedan collided with the pedestrian and continued northbound on I-680. Immediately after the initial collision the pedestrian was struck by an Audi SUV (driven by a 29-year-old male from Oakley) and a Toyota Corolla (driven by a 22-year-old female from Concord). The drivers of the Audi and Toyota stopped on scene and provided statements to officers.

At this time alcohol or drugs do not appear to be a factor in this collision. This collision is still under investigation and if anyone witnessed this collision or the events leading up to it, please contact Officer Mitchell at Contra Costa CHP (925) 646-4980.

On Tuesday, January 10, 2017 at about 8:58 am, Contra Costa CHP was advised of a three vehicle traffic collision at southbound I-680 at Contra Costa Blvd. Upon CHP and emergency personnel arrival, the driver (77 yr old male from Danville) was unconscious and unresponsive within his vehicle, a white Ford F-250.

In the initial investigation, it appears that the driver was traveling on southbound I-680 just south of Monument Blvd. For unknown reasons, the driver veered to the right across the lanes and struck two vehicles, a Ford Edge and a Hyundai Sonata. (Both of those drivers were uninjured and vehicles sustained minor damage) The white Ford truck continued to veer right and drove off the roadway and through a cyclone fence. The driver continued across Contra Costa Blvd and collided into an unoccupied house.

Emergency personnel on scene immediately began life-saving procedures and CPR and he was quickly transported to John Muir hospital in Walnut Creek for his life threatening condition.

While at the hospital, the maledriver was pronounced deceased. At this time it is unclear if the driver died from his injuries from the collision or a medical condition.

Alcohol or drugs do not appear to be a factor in this collision. This collision is still under investigation and if anyone witnessed this collision or the events leading up to it, please contact Contra Costa CHP at (925) 646-4980.
