The Juvenile and School Resource Unit, part of the Special Services Division, supports school safety, positive youth development, and strong relationships between the Tyngsborough Police Department, students, families, educators, and the community.
The unit is supervised by Sergeant Charles Melanson, who also serves as a School Resource Officer at Greater Lowell Technical High School. Officer Matthew Koziol is also assigned to Greater Lowell Technical High School, while Officer Christopher Gustafson serves as the School Resource Officer for the Tyngsborough Public Schools.
Our School Resource Officers maintain a visible, approachable, and supportive presence within their assigned schools. Working closely with students, school administrators, counselors, families, and community partners, SROs support school safety, emergency preparedness, and behavioral threat assessment while providing education, mentoring, prevention programs, and early intervention when appropriate.
SROs also assist with criminal investigations and legitimate public-safety concerns affecting the school community while maintaining a clear distinction between school discipline and law enforcement. Routine student discipline remains the responsibility of school administrators, and officers emphasize intervention, referral, diversion, and collaborative problem-solving whenever appropriate and consistent with public safety.
Beyond their school assignments, the unit coordinates the Department’s juvenile services function, including juvenile investigations, prevention and intervention initiatives, diversion, and collaboration with families, schools, courts, behavioral-health providers, and community- based organizations.
Through education, prevention, mentorship, and partnership, our goal is to help create safe and supportive schools while building positive relationships with Tyngsborough’s young people.
