Twenty-six-year-old Meaghan Zato, of Oakland, was charged on Monday with assault with a deadly weapon and hit-and-run.
Police say Zato, a student at Hastings College of the Law in San Francisco, struck 25-year-old James Roda, also of Oakland, with her Mercedes early Saturday.
Zato had been attacked by vandals after a friend she was with told them to stop spray painting a library. Police say she was chasing the vandals in her car when she struck Roda. Roda suffered severe head injuries and faces a long recovery.
Zato's attorney, Richard Meier, says his client did not intend to harm anyone.
