As reported by WBPF, during the consented search of Horton’s vehicle, handwritten threats were discovered outlining disturbing plans to “kill everyone” at his former high school, as well as at schools in other states, all scheduled for his 22nd birthday on January 2, 2026.

At the time of his arrest, Horton IV, who has a documented history of mental health challenges, was initially placed under the provisions of Florida’s Baker Act.
Speaking to WPF, his mother, Marcie Horton, pleaded for him to receive the necessary mental health care rather than facing charges. She emphasized that her son, despite his disturbing plans, is fundamentally a “good kid” and wouldn’t have carried out his threats. It’s no excuse for what he wrote. I’m not saying that, but he needs help,” she said.
Alisha Horton, Henry’s stepmother, who was on his hit list, also supported his innocence and called for him to be treated for his mental disability rather than prosecuted as a criminal. “Henry isn’t going to hurt me,” she told the outlet. “He would never… He needs to be treated for a mental disability instead of as a criminal.”
Henry Horton IV’s Mother, Marcie, Says He Was Pumped ‘Full Of Medicine’
According to Horton’s mother, he voluntarily admitted himself to a mental hospital while residing with his stepmother and father in Virginia.
However, she noted that despite the two-week stay, he remained undiagnosed. Expressing her frustrations, Marcie said, “All they did was pump him full of medicine.”
Alisha, his stepmother, also shared that she implored the prosecutor’s office not to impose a no-contact order and to facilitate Henry’s treatment. Nevertheless, a no-contact order was issued, accompanied by the $1 million bond, leaving Henry incarcerated.
Both Alisha and Marcie emphasized his need for mental health treatment and a diagnosis, asserting that he poses no threat to society. “He is not getting the treatment that he needs,” Alisha said. “All they are doing is making him a criminal when he needs help. He needs help to figure out what is going on mentally.”
