Story summary

Matthew Bjornholt, a 27-year-old man from Arizona, is facing felony charges for allegedly plotting a mass casualty attack on a religious site. Prosecutors claim he planned to use explosives and firearms to target Jewish or Muslim houses of worship. During his initial court appearance on October 19, 2026, in Maricopa County, prosecutor Stephen Garcia sought a $500,000 cash bond, citing Bjornholt as an imminent danger to the community. According to Garcia, Bjornholt possessed "The Anarchist Cookbook," a manual linked to the Oklahoma City bomber Timothy McVeigh, which prosecutors argue was central to his alleged plans. The plot allegedly involved detonating bombs followed by gunning down survivors with assistance from another individual.
