A 14-year-old boy was taken into custody Friday after a social media post raised fears of a possible school-shooting threat at Mount Baker Middle School in Mount Vernon, Washington. Staff at the school reported the post, triggering an immediate investigation that ended with the teen in police custody the same day.

According to KOMO News, Mount Baker Middle School staff flagged the social media post indicating a possible threat and notified the school resource officer, who began working the case alongside staff right away. That rapid handoff reflects the structure built into Mount Vernon's schools: the police department maintains a dedicated Middle School Resource Officer assigned jointly to Mount Baker and LaVenture Middle School, according to the City of Mount Vernon, giving campuses a direct law enforcement liaison for exactly this kind of report.

The investigation led to the student being taken into custody in connection with the threat, and investigators believe he was acting alone, the station's report notes. Mount Vernon authorities released limited information about the case and thanked those who reported it promptly, though officials have not disclosed further details as the investigation continues.

How the Tip Reached School Officials

Mount Baker Middle School lists the Vector Solutions SafeSchools Alert system as a way to report concerns, per Mount Baker Middle School. The incident highlights the importance of reporting safety concerns promptly. Mount Baker serves roughly 569 students in grades 6 through 8, according to data from Niche.

Mount Vernon School District cooperated with officials throughout the incident, and that cooperation was instrumental in ensuring the safety of students and staff, per the same account.
