Xaelyn Dunbar, 19, has been charged with making a terroristic threat by intentionally and knowingly threatening to commit violence. He allegedly suggested in a Sept. 15 Facebook comment that he planned to use his truck to disrupt the vigil, which drew roughly 1,000 people later that evening, the San Antonio Express News reported, citing an arrest affidavit.The threats surfaced on the Facebook page of the San Antonio Young Republicans, which was promoting the campus vigil for Kirk, the Turning Point USA co-founder who was assassinated on Sept. 10 while speaking at Utah Valley University.YEARS OF CAMPUS ATTACKS ON CONSERVATIVE ACTIVISTS RESURFACE AFTER CHARLIE KIRK’S MURDER"This is a disgrace and I can tell you right now ima make sure this won’t be a good nor comforting vigil yall watch and see.
