The boy had been standing with two friends in the 7000 block of Brentwood Boulevard when, at about 9:15 p.m., a black Honda Civic or similar-looking car occupied by two males drove by.
One of the suspects fired shots at the group, striking the 14-year-old in the chest, Misquez said. Police found the boy a block from the crime scene, at Pasco Drive and Little John Way.
A crowd of 30 or more people gathered in the street as police officers attempted to render first aid to the boy, Misquez said.
Two of the boy's family members were arrested after they allegedly refused to listen to officers' warnings to stand back. Police used a Taser to subdue the family members after they allegedly became "combative," police reported.
"Our number one priority was to save the boy's life and seek the suspects," Misquez said.
Investigators were following up on leads in the case today, but the shooters have not been arrested.
At least one of the victims was known to associate with a local gang, Misquez said, but it was too early in the investigation to know whether the shooting was gang-related.
The boy was airlifted to John Muir Medical Center in Walnut Creek.
