A 17-year-old Concord boy was charged with murder for allegedly driving the suspect car, police said. Also, another 17-year-old Concord boy was charged with hiding the gun after the shooting, according to police.

The names of the latter two individuals were not shared because of their ages.

Five suspects were arrested in the shooting. No charges were filed against the fifth suspect, who is also a male juvenile, police said.

The shooting happened after school had let out for the day. A person allegedly got out of a black 4-door sedan and approached a group of people who were off campus and shot at the 17-year-old victim as others ran for safety, according to police.

Police have identified the victim as Lawrence Janson of Concord.

Police said Janson then ran onto the school campus, where a janitor found him and staff members, paramedics and police attempted to treat him for his wounds. Janson was taken to the hospital, where he was pronounced dead, according to police.

Investigators don't believe the shooting was gang-related, as none of the suspects is a documented gang member.

Police used surveillance video to help find the suspects and were also able to recover the gun and the vehicle that were used in the shooting.

While police believe that the shooter targeted Janson, they have not determined a motive.
