OXNARD, Calif. (AP) — A 15-year-old boy was shot and wounded in a junior high school computer lab Tuesday and another eighth-grader was taken into custody, authorities said.

Worried parents gathered outside the 1,150-student E.O. Green Junior High School, which was locked down. Students were released classroom by classroom.

The wounded boy had improved since arriving at St. John's Regional Medical Center in extremely serious condition, police spokesman David Keith said. "We are guardedly optimistic he will make a recovery," he said.

The 14-year-old suspect was being booked for investigation of attempted murder, Oxnard Police Chief John Crombach said
