A Texas man with “radical ideology paraphernalia” was thwarted last week after authorities intercepted a message detailing his plans for a mass shooting at a Walmart store, police said. Coleman Thomas Blevins, 28, was arrested north-west of San Antonio in Kerrville, Texas, on Friday for a terroristic threat to create public fear of serious bodily injury. “Many think ‘that can’t happen here’, and it was well on the way to happening,” said the Kerr county sheriff, Larry Leitha, adding that investigators “possibly saved many lives”. “The plot interrupted in this case is unthinkable,” he said. During a week-long operation, law enforcement “made contact and conversed with” Blevins, who is white, confirming “his affiliation and networking with extremist ideologies”, according to a news release. After arresting Blevins, authorities searched his residence, where they found firearms, concentrated THC, ammunition, electronic evidence and what they dubbed “radical ideology paraphernalia” such as books, flags and handwritten documents.
