A South Florida man was arrested after police found handwritten threats in his car outlining plans to “kill everyone” at his former high school and others across multiple states on his 22nd birthday.
Henry Horton IV, 19, was pulled over in Jupiter on Sept. 27 for a broken headlight when a search of the vehicle uncovered the alleged plans, WBPF reports.
One of the notes read, “kill everyone at OHS with my guns.” Horton allegedly confessed that it referred to Okeechobee High School, where he graduated in May 2022, according to the probable cause affidavit.
Police said the notes ultimately outlined a plan for Horton to kill an administrator at the school, along with 14 others on the campus on January 2, 2026, the day he turns 22.
Police reportedly discovered plans in his phone and on his Discord account that outlined mass murder plots in numerous states, as well as plans to murder his stepmother and even create a bomb.
During his interview with authorities, Horton allegedly stated that he was preparing an attack on a church in Miami and had done reconnaissance in Parkland, where Marjory Stoneman Douglas High School is located. In 2018, 17 people were murdered at the same school.
He was admitted to a hospital for mental health difficulties and was officially arrested on Thursday. On a $1 million bond, he is being held at the Palm Beach County Jail.
