ST. JOSEPH, Mich. - An image circulating on social media that possibly contained a threat to St. Joseph Public Schools was deemed not legitimate, St. Joseph High School Principal Greg Blomgren said in a letter to families on Monday.

At 9:30 p.m. on Sunday, the Lincoln Township Police Department contacted St. Joseph Public Schools administration about a threat to a school made on Snapchat.

According to reports, there was no name attached to the screenshot sent to police and no school identified in the screenshot.

The image originally circulated among students at Upton Middle School and eventually circulated among students at the high school. In both cases, law enforcement confirmed there was no threat to either school.

The investigation found that the student in the image does not attend St. Joseph Public Schools and that the image is from some time ago of someone who lives on the other side of the state.
