A Santa Rosa woman killed when her car collided with another vehicle on Highway 101 and careened off the road was identified Thursday as Rogina Cruz-Valentine, 43, Sonoma County Coroner’s Office officials said.

CHP officers suspect Cruz-Valentine was under the influence of methamphetamine when she swerved into an adjacent northbound driver at about 7:45 p.m. Wednesday, Officer Jon Sloat said. Cruz-Valentine was not wearing a seat belt, the CHP said.

From the center lane near Wilfred Avenue in Rohnert Park, Cruz-Valentine’s 1991 Honda Accord veered into the slow lane, swiping a 1996 Toyota 4Runner, the CHP said.

The impact sent the Toyota, driven by Yolanda Nunez, 41, of Santa Rosa, onto the right shoulder. Nunez over-corrected, sending the Toyota back onto the highway and into the path of the Honda, Sgt. Robert Boyer said in a CHP report.

The vehicles collided and crashed into the center divider wall. Then the Honda crossed back over the lanes to the right shoulder, went down an embankment and came to rest, the CHP said.

Paramedics took both women to Santa Rosa Memorial Hospital, where Cruz-Valentine was pronounced dead. Nunez was treated for pain in her neck and back and released, according to the CHP.
