School threats, related violence has increased in the week after the Antioch High School shooting, Nashville Police say.

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.

Police said a male student shot two people at the high school on Wednesday morning before turning the gun on himself.

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

Two local students were arrested in unrelated cases for making school threats Thursday. In the first case, Dorrian Harp, an 18-year-old student at Hunters Lane High School, allegedly admitted to telling another student in his class on Tuesday that he would shoot up the school the next day.

Nashville police and schools are monitoring social media discussion and concerns Thursday as people speculate if additional schools could be targeted after a 17-year-old student opened fire Wednesday at Antioch High School, killing himself and a 16-year-old girl while injuring another, officials said.

Threats against schools and institutions are taken very seriously by the MNPD. Those responsible, once identified, will be prosecuted.”
