California Highway Patrol-Solano investigators are seeking answers to what prompted the driver of a stolen car on eastbound Interstate 80 to lead officers on a high-speed pursuit early Monday from Fairfield to Vacaville, where the car crashed into a concrete median barrier, seriously injuring three of four of the vehicle’s occupants.

In a CHP-Solano social media post on Monday, the author indicated that, at 2:35 a.m., area patrol units were notified of a stolen gray 2004 Honda Accord traveling eastbound on I-80.

Sgt. Langford located the Honda west of Airbase Parkway, in Fairfield, where CHP officers attempted to stop the vehicle, but, a pursuit ensued with speeds reaching 130 mph, according to the post.

The Honda exited I-80 at the Leisure Town Road off-ramp in Vacaville at a high rate of speed and collided with a concrete median barrier.

Officers stopped and immediately began rendering medical aid to the driver and three other occupants.

The driver, the left rear passenger, and the right rear passenger suffered unspecified “major injuries,” while the right front passenger received minor injuries.

While being treated for injuries, a loaded handgun was allegedly located on the driver of the Honda. The handgun was taken and booked as evidence.

The investigation continues, and the post indicated felony charges will be filed with the Solano County District Attorney’s Office in Fairfield.
