The Metro Nashville Police Department opted to permanently add a third school resource officer to Antioch High School as students return Tuesday.

The deadly shooting is the latest to rock the Nashville community nearly two years after another school massacre sparked a debate for gun reform.

Two students were shot by another student before turning a gun on himself at Nashville ’s Antioch High School on Wednesday, according to police. Police were called to the school at 11 a.m. ET, according to the Metropolitan Nashville Police Department. The suspected shooter is “no longer a threat,” police said.
