Juvenile Arrested for Unlawful Carrying of a Weapon on School Grounds

Chatfield High School Teacher Targeted

Jefferson County, CO. – A 16-year-old Chatfield High School student was arrested on March 31, 2026, after deputies learned that they planned to kill a teacher at the school.

Investigators say the student took a 7-inch butcher knife from their kitchen that morning, concealed it in a backpack and took it to school. In the early morning, the student attended the targeted teacher’s class with the concealed knife inside of the backpack. The student did not act on the plan and instead went to the school office with the backpack, asked to speak with a counselor, and disclosed what they had intended to do. The knife was confiscated and the School Resource Officer assigned to the school was notified.  

The student was arrested and booked into the Marvin W. Foote Youth Services Center for unlawful carrying of a weapon on school grounds—although additional charges may be filed. The suspect’s first court appearance is later today.
