"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," the New York Post reported.

"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," it continued.

"Authorities asked him where he was heading before getting stopped. Horton said he was traveling to Miami to look at a church, where he told investigators he planned to kill around 10 people following his planned 2026 attack at his former school, according to the affidavit," WSVN reported.

"Horton was transported to a hospital to receive a mental health evaluation under the Florida Mental Health Act, commonly known as the Baker Act, which allows people to be involuntarily detained and subject to an examination for up to 72 hours during a mental health crisis," it continued.

Horton was later arrested on a charge "with intimidation with written threats to kill or harm another individual," according to the report.

The situation is of added concern after a mass shooter killed 17 people at a Parkland, Florida, high school in 2018.

Horton is currently held at Palm Beach County Jail on a $1 million bond. He is scheduled to appear in court on Nov. 6.

Officers have been applauded for this swift action that may have saved the lives of many.
