Ohio supporter of ISIS pleads guilty in attempted attack on Jewish synagogue Updated May 18, 2021; CLEVELAND, Ohio -- A Northwest Ohio resident admitted Tuesday that he planned to carry out a mass shooting at a synagogue to show his allegiance to ISIS. Damon Joseph, 23, of Holland pleaded guilty in U.S. District Court in Toledo to charges of attempting to provide material support to a terrorist organization and attempting to commit a hate crime. He faces 20 years in prison when Judge Jack Zouhary sentences him Sept. 14. Authorities arrested Joseph on Dec. 7, 2018, moments after he grabbed a duffel bag that contained two semi-automatic rifles from an undercover FBI agent’s car. Unbeknownst to Joseph, agents disabled the weapons.
