Thousands of texts between Corey Johnson and an online Muslim girlfriend showed his drift toward violence in the days before he stabbed a 13-year-old boy to death and tried to kill two other people. A jury is considering a murder charge against Johnson following the March 2018 attacks at a Palm Beach Gardens home. The texts showed graphic images, many of which Johnson found on Islamic State websites. Johnson had developed an interest in Islam, and his attorneys say these images helped drive him to kill. They also said the girlfriend broke up with him days before the attacks.
