MOORESVILLE, Ind. — An 18-year-old Mooresville High School student was arrested after federal and local authorities uncovered an alleged plan to carry out a mass shooting at the school on Valentine’s Day, WTHR reported.
The suspect, identified as Trinity Shockley, was taken into custody on Feb. 12 and remains jailed without bond, according to the report.
The investigation began after the FBI received an anonymous tip through the Say Something reporting system, stating that Shockley was planning an attack and had access to an AR-15 rifle and a bulletproof vest. Mooresville police, working with federal and county law enforcement, identified Shockley as the suspect and executed a search warrant at Shockley’s home, according to the report.
Authorities recovered evidence linking Shockley to past mass shootings, including photos of convicted shooters Nikolas Cruz, Dylann Roof and Andrew Blaze. Investigators also found multiple AR-15 magazines and ammunition in a bedroom belonging to Shockley’s father, according to the report. Notebooks containing violent writings were also discovered, with references to school shootings and expressions of admiration for Cruz.
Shockley allegedly discussed the plan on Discord, posting messages that included “I’ve been planning this for a YEAR” and “Parkland part two,” referring to the 2018 school shooting in Florida. The suspect also reportedly wrote letters to Cruz in prison and kept a locket with his photo inside, according to the report.
During an interview with detectives, Shockley claimed the statements were meant as a joke and denied having access to firearms. However, investigators noted a history of attempts to seek mental health treatment, which court records indicate were blocked by Shockley’s father.
Shockley has been charged with conspiracy to commit murder and two counts of intimidation with a threat of terrorism, according to the report.
Local officials and school administrators praised the swift response by law enforcement. Mooresville Schools confirmed that Shockley would not return to the school and reassured families that mental health resources remain available for students.
FBI Indianapolis also released a statement, confirming that agents coordinated with Mooresville police to assess and address the threat. Mooresville Police Chief Kerry Buckner called the situation “disturbing,” emphasizing the importance of community vigilance in preventing potential violence.
