Arcadia police investigators have completed an inquiry into the April 10 crash, in the 600 block of West Duarte Road, that killed 16-year-old Arcadia High School student Alice Zhang. Detective Michael Hale said the driver was negligent in driving a car with a dirty windshield that blinded him as he drove toward a setting sun. Arcadia officials are recommending the driver of the 1997 Lexus sedan that struck Alice Zhang and her friend who survived, be charged with vehicular manslaughter, but the District Attorney's office will review the case and decide on whether to prosecute the driver and on what grounds.
