By Jimmy Lee, Director of Public Affairs, Contra Costa County Office of the Sheriff

On Tuesday, February 11, 2020, at about 3:24 PM, the California Highway Patrol received a call of a rollover vehicle accident in the area of Kirker Pass Road and Hess Road near Concord.

During the initial CHP investigation, it was discovered that the cause of the accident was apparently domestic-related. The Office of the Sheriff responded to the location and started an investigation.

Deputy Sheriffs found the incident involved a woman and a man who were in a previous relationship. The woman and two others were driving in a tan colored 2004 Chevy Tahoe SUV. The suspect, who was in a white colored 2015 Mercedes Benz, followed behind and later pulled in front of the victim’s car causing her to lose control and flip over an embankment.

The driver of the Chevy Tahoe, who was ejected from the vehicle according to ConFire personnel, was taken to a local hospital and is said to be in critical condition. According to the CHP many vehicles pulled over and passersby helped turn the vehicle onto its side. One of the other occupants, a little girl, was treated and released from the hospital. The last occupant of the SUV was uninjured.

The driver of the other vehicle was later arrested by Deputy Sheriffs. He is identified as 28-year-old Alejandro Arriaga of Concord. He was later booked into the Martinez Detention Facility on three felony counts of assault with a deadly weapon and one felony count of child cruelty. Arriaga is being held in lieu of $190,000 bail.

Anyone with any information on this case or who might have witnessed it is asked to contact detectives at (925) 313-2600. Tips could be emailed to: or call (866) 846-3592 to leave an anonymous voice message.
