Why it matters

This incident raises concerns about school safety and the mental health of young children, as a 10-year-old allegedly carrying out a violent attack on a younger student is highly unusual and concerning for the community.

The details

According to police, the 7-year-old victim was participating in an after-school program at Benjamin Bubb Elementary School when the 10-year-old boy, who was not enrolled in the program, allegedly stabbed her three times in the shoulder with what is believed to have been a kitchen knife. The school was placed on lockdown as authorities responded and located the suspect, who had initially fled the scene. The 10-year-old was then detained and transferred to a juvenile mental health services provider.

• On March 12, 2026, around 3:30 p.m. local time, the Mountain View Emergency Communications Center received reports of a student being stabbed at Benjamin Bubb Elementary School.
• The 7-year-old victim was treated at the scene by the City of Mountain View Fire Department before being released to a parent.
