Law enforcement officials seeking a motive for a shooting at Nashville’s Antioch High School on Wednesday morning are examining alarming social media posts and writings tied to a teenager police say shot and killed a 16-year-old girl.

The suspected shooter who killed one student at a high school in Nashville on Tuesday has been identified as Solomon Henderson, 17.

One student is dead and another is wounded after a third student opened fire with a pistol Wednesday at Antioch High School in Nashville, Tennessee, police said. The 17-year-old shooter then shot himself and died, according to police.

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.

Nashville investigators say they believe the teenager who opened fire in a high school and killed a girl before killing himself was influenced by material found on "harmful" sites.

Police said the suspected shooter sustained a self-inflicted gunshot wound and the school district said Antioch High School is on lockdown.

The position of the camera and the shooter led to an AI-powered weapon detection system failing to pick up on a student's gun.

Mayor Freddie O'Connell on Thursday announced a new Community Foundation of Middle Tennessee fund for victims in the Antioch High shooting.

In the months leading up to the shooting, Kara's husband wrote an email to the school condemning guns found on campus and emphasizing the need for metal detectors.

One of the 12-year-olds threatened to shoot four of his classmates, the other posted a threat on Instagram and an 11th grader threatened “Antioch part two,” according to police.
