Police have identified the person responsible for this week’s threat against a Laguna Middle School. San Luis Obispo P.D. investigators say a 13-year-old female student, egged-on by two of her friends, wrote “School Shooting 12-02-19” on a girl’s bathroom mirror. Authorities believe the threat was written to support a trend on the social media app TikTok that urges students to skip class on December 2nd. Police say the student’s actions will be dealt with by the school district, adding that there is no ongoing threat to Laguna Middle School.
