According to an affidavit filed in court, authorities placed Plume under an emergency order of detention for homicidal threats on Feb. 18 and took him to a mental health hospital in Midwest City. The original police report states that the next day, while at the hospital, Plume told a case manager that the Florida shooting inspired him to "shoot up" Lawton High and that he owns multiple guns at his parents' house in Lawton.
