A Marin County woman raised in Santa Rosa died Monday in a Southern California crash involving a head-on collision with a tour bus.

Kristina Carey, 55, was killed in the Highway 58 crash in San Bernardino County, according to the San Bernardino County Coroner’s Office.

The CHP is investigating why the bus drifted into Carey’s lane. The bus hit her Subaru and another car, flipping all of the vehicles. A total of 26 people suffered injuries, including nine people with life‑threatening injuries, according to authorities.

Kristi Jones was born and raised in Santa Rosa and graduated from Montgomery High School in 1979, said her father, Steve Jones of Rohnert Park. She graduated from Santa Rosa Junior College and University of California, Santa Cruz then earned a master’s degree at San Jose State University.

She lived in Terra Linda with her husband, Phil Carey. She also is survived by her daughter, Melissa Carey of Los Angeles and mother Inya Laskowski of Guerneville and Truchas, New Mexico, said Steve Jones. Kristi Carey’s younger brother, Eric Jones Laskowski, died in a motorcycle crash in 1982.

Kristi Carey had worked as a social worker and counselor and Monday was on her way home from a trip that included a counselors’ conference in Irvine, a visit to Joshua Tree National Park and time with her daughter, said her father.

“She was a dear daughter,” he said.
