SANTA ROSA (CBS SF) — Authorities in the North Bay are searching for a suspect who allegedly stabbed a rideshare driver in Santa Rosa on Christmas Day, according to the Sonoma County Sheriff.

The sheriff’s official Facebook account posted about the incident Monday afternoon. Authorities said that on December 25 at about 6 p.m., a rideshare driver picked up a passenger in Santa Rosa on the 1700 block of Yulupa Avenue. After taking the passenger to the entrance of Shiloh Ranch Regional Park, the passenger attacked the driver from the back seat with a sharp object, stabbing the victim twice in the neck and once on the elbow. The suspect then got out of the car and left the scene.

The victim proceeded to drive himself to an area hospital for treatment and and is expected to survive his injuries, authorities said. Detectives investigating the case since Saturday have identified the suspect as 19-year-old Santa Rosa resident Tristan Mathew Hardin.
