Friends identify the victim as 17-year-old Lawrence Janson.

Evidence markers dotted the intersection where someone shot the student just after Olympic High School let out for the day.

"I was walking a guest out to the driveway to her car when I heard four pop, pop, pops," aid witness Pam Smithberry.

Smithberry lives near Salvio and Beach streets in Concord. She says she heard the shots around 1:30 p.m.

That's when police say a black sedan pulled up. Someone got out and shot Janson standing in a group.

"As soon as I heard I just came down here and just sat here, I've sat here for an hour now," said the victim's friend Calvin Machado.

Machado says Janson was a student at Olympic Continuation High School.

A janitor found him and staff tried to treat his wounds but the teen later died at the hospital. Police have not released his identity.

"He was a cool guy. I don't know he was just at my house the other day too. I was hanging out with him," Machado added.

Officers say the teen was targeted and shot multiple times. Bystanders had to duck for cover as a bullet went into a nearby office. The shooter got away.

No further information on the suspects or how many arrests were made were immediately available.
