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

After a shooting at Antioch High School, hundreds of students gathered outside the Tennessee Capitol hours ahead of a special session inside the House and Senate chambers this week.

Police say a shooting at a Nashville high school has left one student dead and another woulded. Metro Nashville Police spokesperson Don Aaron said during a news conference that the 17-year-old gunman later shot and killed himself with a handgun.
