(09-29) 18:54 PDT -- A woman has been arrested on suspicion of vehicular manslaughter for allegedly crashing her speeding Mercedes into a minivan in San Francisco's Western Addition, killing a 16-year-old boy and injuring several people, police said Sunday.

The suspect, whose name has not been released pending a review of the case by prosecutors, was booked early Saturday at San Francisco County Jail after being medically cleared, said Police Chief Greg Suhr. She was being held on suspicion of vehicular manslaughter with gross negligence, Suhr said.

Police said it did not appear that drugs or alcohol were factors in the crash Friday at Pine and Gough streets that killed 16-year-old Kevin San of San Francisco. But investigators have declined to discuss the circumstances leading up to the collision.

Police said the woman was driving a Mercedes-Benz at speeds of up to 80 mph west on Pine Street when she rear-ended the minivan while it was stopped at a light at Gough Street just before 7 a.m. The impact caused both vehicles to roll over.

San, a student at Lincoln High School, was killed and his mother and his sister were seriously hurt, authorities said. The driver of the Mercedes walked away from the crash with minor injuries, police said.

A catering van at the corner was also struck. Three people inside the van suffered injuries that were not life-threatening.

Witnesses told police that the woman had been speeding for at least several blocks before the crash, Suhr said.

The chief said officers on patrol had seen the Mercedes speeding moments before the crash happened but that the car was going so fast police didn't have time to activate their lights and sirens to go after her.
