Grief counselors were on hand Monday at Lincoln High School in San Francisco - the school attended by a 16-year-old killed Friday morning in a horrific crash.
In addition, the school will be honoring Kevin San all week, with posters available for signing at lunch time so that students can express their condolences. Over the weekend, a growing memorial to Kevin was created to honor his brief life. Kevin was a drummer in the ROTC band.
"This difficult time can be stressful and confusing," Principal Barnaby O. Payne wrote on the school's website. "We especially want you to know of our care and support. I am confident that the love of our school community will embrace Kevin’s family and his memory."
Friend Stephanie Acedillo told NBC Bay Area that she is devastated. "Kevin was so nice, always upbeat, always had a smile," she said.
Kevin was killed in the 7 a.m. crash in San Francisco's Lower Pacific Heights neighborhood, and his mother and sibling were critically injured on their way to school.
"This is about as ugly an accident that I've ever seen," Police Chief Greg Suhr said at the time. "And when you lose a child, it just doesn't get worse than that."

Police arrested 58-year-old Jennie Zhu on charges of vehicular manslaughter with gross negligence, though by Monday, jail records showed she had bailed out of custody. Witnesses told police the driver appeared to have been driving at speeds of up to 80 mph - in a 25-mph zone - at Pine and Gough streets when her silver Mercedes-Benz smashed into Kevin's mother's car. The Mercedes also smashed into a catering truck with three inside - however, these injuries were not severe.
After the crash, witnesses said the driver got out and put her hands behind her head. She was not seriously injured.
On Monday, NBC Bay Area knocked on Zhu's door, but no one answered. Someone also hung up when NBC Bay Area made a phone call to her house.
Zhu's neighbor, Marina Schmidt, said she was in shock at what happened and can only guess that something mechanical might have gone wrong with Zhu's Mercedes.
Zhu owns a daycare, Schmidt said, and called her very "nice."
"I think something was (wrong) with the car," Schmidt said.
Aerial images taken from NBC Bay Area's chopper showed two cars flipped on their sides with extreme damage. Firefighters and emergency crews poured what appeared to be salt on the roadway, and a Muni bus was stopped with lights blinking just behind the accident.
