BERKELEY (CBS SF) — A traffic collision involving three vehicles early Sunday on eastbound I-80 led to two fatalities after the drivers were struck standing on the freeway while arguing after the crash.

Upon arrival on scene, officers located a Chevrolet Malibu, a Dodge Durango and a Mini Cooper. The vehicles all had collision damage and were blocking the #1 and #2 lanes. The officers then discovered two unresponsive male adults laying on the roadway ahead of the collision scene. Both adults appeared to have sustained fatal injuries.

The preliminary investigation indicates the Chevrolet Malibu and Dodge Durango were involved in a non-injury car crash on I-80 eastbound. The two male drivers and one female passenger exited their respective vehicles, into lanes of traffic, and commenced to argue about the collision.

As the parties were outside of their vehicles in the lanes of traffic, an on-coming Mini Cooper struck the two male drivers outside their vehicles. The female passenger was possibly struck by debris and was transported to the hospital for minor injuries.

Drugs and alcohol do not appear to be a factor in this collision.

The identity of the deceased was being withheld pending notification of next of kin. Any inquiries regarding the identity of the deceased should be directed to the Alameda County Coroner.
