The minor, whose name has not been released, was at Stanford Hospital, where he's being treated for injuries from the crash that are not considered life-threatening. Wagstaffe said his office planned to file charges once the driver was released from the hospital, which could be within the next few days or weeks.
Four other passengers were also injured in the Nov. 4 collision, including two in the teen's car and the 7-year-old twin daughters of San Carlos residents Gregory Ammen, 44, and Grace Spiridon, 42, who died in the crash. Spiridon, a Google employee, and Ammen, an audio engineer, grew up in Palo Alto.
The cause of the collision remains under investigation, according to the Redwood City Police Department. No other information has been released.
Though no formal plans had been announced, Wagstaffe said that vehicular manslaughter, which can be filed as either a misdemeanor or felony, was one of the charges being considered. While a misdemeanor vehicular manslaughter conviction is punishable by up to a year in county jail, a felony conviction could confer up to six years in a state prison.
Though the identity of the teen driver has not been made public, the Sequoia Union High School District has offered aid to its community.
"As a result of the tragedy, the district did provide additional support services for our students and staff," said spokesperson Richard Gebin.
