A motorcyclist suffered major injuries Sunday after a hit and run crash on Highway 4 in Discovery Bay, and a second head-on crash involving the fleeing vehicle in the same general area also resulted in major injuries, according to the California Highway Patrol.
Both directions of the highway were shut down for about two and a half hours as multiple helicopter transports and ambulances were called to the crash scenes, the CHP said. At least six people were injured in the crashes, and the CHP said all parties were taken to hospitals, except the driver of a white Subaru involved in both collisions.
The Subaru's driver, Meagan Kathleen Campbell, 33, of Discovery Bay, was arrested on suspicion of felony DUI, CHP Officer Brandon Correia said.
According to the CHP, the first collision was reported at 5:12 p.m. at the Highway 4-J4 junction. The second crash, at Highway 4 and Discovery Bay Boulevard, was called in about 12 minutes later, at 5:24 p.m, and involved the same Subaru that fled the scene of the motorcycle crash.
The second collision was reported as a head-on crash with a Saturn sedan carrying five people, the CHP said.
Anyone who witnessed the collisions or the events leading up to them should contact Contra Costa CHP by calling the non-emergency 911 number at 707-641-8300.
