A Florida guy was arrested after being discovered with notes detailing plans to ‘murder everyone’ at his previous school.
A 19-year-old male from South Florida was detained when police uncovered scrawled threats in his car, where he had planned to “kill everyone” on his 22nd birthday at his previous school. He had also declared a desire to kill individuals in several states.
On September 27, police arrested Henry Horton IV in Jupiter for a broken headlight. This is when they searched his car and discovered his purported plans. A probable cause affidavit indicated that they discovered a message that read, “kill everyone at OHS with my guns,” alluding to Okeechobee High School, where he graduated in May 2022. He is said to have confessed.
According to cops, Henry and 14 other students planned to murder a school official on January 2, 2026. Police then searched his phone and Discord account and discovered that he had intended to carry out further mass killings across states, create a bomb, and murder his stepmother.
According to the Palm Beach County Sheriff’s Office, Henry admitted during an interrogation 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 planned.
Henry also claimed to have performed recon work at Marjory Stoneman Douglas High School, where gunman Nikolas Cruz killed 17 people in 2018. Police also seized a 9MM handgun that Henry is accused of stealing from his mother.
‘He should be treated for a mental disability rather than as a criminal.’
Henry has struggled with mental health issues and was admitted to a facility under Florida’s Baker Act. He has now been apprehended.
Marcie Horton, Henry’s mother, did not justify her son’s behavior, but instead requested officials to allow him to obtain mental health therapy rather than face prosecution. According to WPF, she also stated that he was a “good kid” who would not have carried out the attack in real life. “It’s not an excuse for what he wrote,” she remarked. “I’m not saying that, but he needs help.”
Alisha Horton, Henry’s stepmother, also claimed he was innocent. “Henry isn’t going to hurt me,” she assured herself. “He’d never… He should be treated for a mental illness rather than as a criminal.”
Henry was arrested and jailed at the Palm Beach County Jail on charges of intimidation with written threats to kill or harm another person. He’s being jailed on a $1 million bond and is due in court on November 6.
