Sonoma County Sheriff's Office say a rideshare driver was stabbed and injured by a rider on Christmas Day in what they are calling a random act of violence. The sheriff's office has identified a suspect. 

The driver, from an undisclosed rideshare app, picked up a passenger on the 1700 block of Yulupa Avenue in Santa Rosa at around 6 p.m., the sheriff's department said. 

The sheriff's office said the driver drove the passenger to the entrance of Shiloh Ranch Regional Park, when the suspect stabbed the driver twice in the neck and once in the elbow.
