Authorities say they are investigating the possibility that as many as six Ringgold Middle School students may have threatened to shoot up their school on Friday. Classes were cancelled in the district Friday after district officials said they received a tip through the district’s Safe2Say Something Program. Authorities say the juveniles have been questioned and police are still trying to determine if there was an actual plan or talk about violence. The Safe2Say Program was created by the State Attorney General’s Office to allow individuals to report concerns about safety in schools.
