According to police, Henry was plotting to kill an administrator at the school, along with 14 others on the campus on January 2, 2026.

The Palm Beach County Sheriff’s Office said that Henry confessed during an interview that he was in Palm Beach County to do reconnaissance on the El Rey Jesus Church, in Miami, as part of the attack he was planning, according to New York Post.
Henry also claimed that he did recon work at the Marjory Stoneman Douglas High School, where gunman Nikolas Cruz shot dead 17 people in 2018. Police also seized a 9MM handgun Henry allegedly stole from his mother.
‘He needs to be treated for a mental disability instead of as a criminal’
Henry has battled mental health problems, and was transported to a hospital under Florida’s Baker Act. He has now been arrested.
Henry’s mother Marcie Horton did not defend her son’s actions, but asked officials to let him receive the mental health treatment rather than face charges. She also said that he was a “good kid” and would not have carried out the attack in reality, according to WPF. “It’s no excuse for what he wrote,” she said. “I’m not saying that, but he needs help.”
Henry’s stepmother, Alisha Horton, also claimed he was innocent. “Henry isn’t going to hurt me,” she said. “He would never… He needs to be treated for a mental disability instead of as a criminal.”
Henry has been charged with intimidation with written threats to kill or harm another individual, and booked at the Palm Beach County Jail. He is being held on a $1 million bond and is set to appear in court on November 6.
