Deputies arrest 11-year-old boy for carrying knives to WA middle school

Deputies arrested an 11-year-old boy at Alderwood Middle School in Lynnwood, Washington, after he brought two knives onto campus, prompting a lockdown. Reports came in around 3:00 p. m. as school had already ended for the day. When deputies arrived, the boy fled but was quickly apprehended.

This incident follows an attempted stabbing in April 2025, where he tried to attack another student but was stopped by a teacher before anyone was injured. After that attempt, he faced charges for second-degree assault and possession of a deadly weapon on school grounds. The school’s administration took immediate action by initiating a modified lockdown to ensure the safety of all remaining staff and students. This pattern of behavior raises concerns about youth violence in schools and the effectiveness of interventions. Local authorities emphasize the importance of addressing such incidents to prevent future occurrences.
