Maryland Teen Arrested for Threatening School Shooting with Disturbing 'Manifesto'

An 18-year-old high school student in Montgomery County, Maryland, has been charged with making threats of mass violence after writing a 129-page document expressing a desire to "shoot up" his high school. The document, described as a "manifesto," contains disturbing passages and references to mass shootings and bomb-making. The student has a history of psychiatric treatment related to homicidal and suicidal thoughts, and authorities have credited Maryland legislation with preventing him from obtaining firearms. The school system has increased security precautions, and the student has not physically attended school since 2022.
