CHP officers suspect a drunken driver caused a head‑on crash on Highway 121 Sunday south of Sonoma, injuring two Rohnert Park residents.

Officers arrested Brigeetty Jimenez, 38, of San Rafael, saying she was intoxicated when her southbound Hyundai Elantra crossed double yellow lines and hit a northbound Toyota Corolla.

The 4:40 p.m. crash happened north of Mangel Ranch Road and Sears Point.

Corolla driver Millen Griffith, 64, and passenger David Griffith, 23, had moderate injuries and were taken to Queen of the Valley Hospital in Napa.

Officers took Jiminez to Sonoma Valley Hospital for treatment of minor injuries then booked her into the Sonoma County Jail.
