Book excerpt: The true story that is the basis for The Conjuring 3: The Devil Made Me Do It opening in theaters June 4, 2021. It began with the lust of demons and the corruption of a young boy named David Glatzel. It ended with a murder trial that made headlines across the country--the trial of Arne Cheyenne Johnson, accused of brutally knifing a friend to death. Johnson's defense startled the nation: not guilty, by reason of demonic possession. Here is the horrifying true story of what happened on terrible summer in the sleepy town of Brookfield, Connecticut. How the Glatzels, an average suburban family, came under a terrifying demonic attack that changed their lives. How their eleven-year-old son, David, suffered monstrous visitations by an entity he could only identify as "the Beast." How a close friend, Arne Cheyenne Johnson, became the tragic victim of forces beyond anyone's control...and how the Glatzels' ordeal has still not ended.
