BERKELEY -- A motorcyclist killed Wednesday after being struck by a car at Shattuck Avenue and Rose Street was identified as 32-year-old Stephan Jarjisian of Berkeley, the Alameda County Coroner's Office said Thursday.

Berkeley police spokeswoman Jennifer Coats said Jarjisian died after being taken to an area hospital.

Coats said the female driver of the car was not injured and is cooperating with investigators. The driver was given a blood test following the crash, but drugs or alcohol do not appear to be a factor, she said.

Coats said investigators have not yet determined which directions the driver of the car or the motorcyclist were heading in when the collision occurred, and they continue to investigate.
