A 10-year-old boy was detained on March 12, 2026, after allegedly stabbing a 7-year-old girl three times in the shoulder with a kitchen knife during an after-school program at Benjamin Bubb Elementary School in Mountain View, California.
Incident Overview
Around 3:30 p.m., the boy—not a student at the school or enrolled in the program—attacked the girl in the play area. She was treated on-site by Mountain View Fire Department medics and released to a parent; she’s now recovering. The boy fled but was identified via residential surveillance video (recognized from prior police contacts) and tracked by a Los Altos PD K-9 unit to his home, where he was detained without incident.
Police and School Response
Officers locked down the school immediately. Custody transferred to Pacific Clinics, Santa Clara County’s juvenile mental health provider—no charges detailed yet due to his age. The district prioritized student/staff support: “Safety is our top priority; staff acted quickly, police responded immediately.”
Community Shock
Residents like neighbor Lori Parsons expressed disbelief: “A 10-year-old with a knife attacking someone? I can’t even fathom.” A third-grader classmate felt scared despite missing the event: “I’m kind of worried about her because we’ve never had that.” No motive released; rare but highlights youth mental health/vulnerability concerns at schools.
