Zhu was booked into San Francisco County Jail Friday and charged with vehicular manslaughter and two traffic infractions. She was quickly released on $300,000 bail.
Police say Zhu was driving a Mercedes at a high-rate of speed, possibly 80 mph, for several blocks before hitting the minivan, sending it airborne on Gough and Pine streets. The van rolled over, killing San instantly. San was a Lincoln High School student where he was a member of the ROTC drum corps.
Grief counselors will be at the high school today assisting students and teachers.
