The investigation into why a Nashville high school student fatally shot a classmate before killing himself has centered on his online writings, which authorities describe as concerning warning signs.
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.
Authorities are examining “very concerning online writings and social media posts” connected to the 17-year-old shooter who killed a female student at Antioch High School.
