The driver, 18-year-old Ramya Ramey of Antioch, also suffered major injuries and was arrested on suspicion of felony manslaughter for killing two passengers and multiple counts of felony DUI for causing major injuries to the other passengers.

“It unfortunately involves underage drinking and driving which is the worst part,” said CHP officer Brandon Correia.

The fatal crash was reported at 4:01 a.m. Sunday. The driver was approaching the Interstate 680 interchange from eastbound Highway 24 when her Honda veered off the highway and overturned onto Boulevard Circle.

“At this time it’s allegations and suspicions, and until we see that toxicology report, we don’t know for sure what happened,” she said.

The crash remains under investigation. Anyone who witnessed the collision, or the events leading up to it, can call the Contra Costa CHP in Martinez at (925) 646-4980 or 1-800-TELL-CHP.
