One woman who crashed her car and a man who came upon the accident scene on Interstate 8 died in what authorities believe is some kind of chain reaction crash. A third driver, who came upon the accident scene after the first two people is now accused of driving under the influence.

Officials say that a 25-year-old woman from Alpine, California, lost control of her Toyota around 3:00 Monday morning. Her car rolled over on the interstate just west of Tavern Road. The Yaris remained in the fast lane on I-8.

Law enforcement says that a 59-year-old man from El Centro, California, arrived at the original crash site in a Chevrolet Silverado. Police do not know what happened when the Silverado arrived. Authorities believe the man either crashed his Silverado into the Yaris, or stopped at the accident site to provide assistance to the woman in the rolled-over car.

A 30-year-old woman from El Cajon is accused of approaching the overturned Yaris next. The woman reportedly was driving an Audi A6 that authorities say crashed into the Yaris.

It is not clear in media reports whether or not law enforcement believes the Audi also struck the Silverado. Authorities say that they do not know if the Silverado crashed into the Toyota before the third car approached. The driver of the Chevy and the Toyota were both killed in the I-8 series of crashes.

Law enforcement reportedly arrested the third driver-the El Cajon woman who police say was driving the Audi. Law enforcement believes that she was under the influence and could face several DUI charges after the wreck.
