On December 9, 2021 at approximately 7:50 a.m. officers from the Mt. Pleasant Police Department (MPPD) responded to a written gun threat found at Mt. Pleasant High School. The school was already in enhanced secure mode when officers arrived. Police conducted a complete security check of the school, and as an extra precaution brought in bomb sniffing dogs. There were no weapons or bombs found during these searches.

While on site, police spoke with the student who initially discovered and reported the threat and found inconsistencies in their statement. That same student later admitted to writing the gun threats on Tuesday, December 7 and Thursday, December 9.

The investigation report was turned over to the Isabella County Prosecutors Office which led to the detention of the 15-year-old student, who is charged with two counts of Intentional Threat to Commit Act of Violence Against the School. One count is a felony, and the other is a misdemeanor.

The Mt. Pleasant Police Department was assisted by Central Dispatch and the Saginaw Chippewa Tribal Police Department.
