On Thursday, investigators intercepted a message indicating that Blevins was preparing to proceed with a mass shooting, in which he made a specific threat that included Walmart. In partnership with the FBI, investigators moved to arrest Blevins after confirming his "affiliation and networking with extremist ideologies" and capability of following through with the threat.

A search warrant was executed at Blevins' residence in the 200 block of Spence Street for seizure of firearms, ammunition, electronic evidence, concentrated THC, and radical ideology paraphernalia, including books, flags, and handwritten documents. (Photo courtesy of Kerr County Sheriff's Office)

Officials noted that the FBI or other federal authorities may seek federal charges in the case and that charges may be added or modified prior to trial. 

"This case reminds us that we need to always be vigilant. Many think ‘that can’t happen here’, and it was well on the way to happening," Sheriff Larry Leitha said in a statement, "Our investigators did outstanding work in this case, and possibly saved many lives. The plot interrupted in this case is unthinkable. We appreciate the assistance of all our law enforcement partners, including the FBI, DPS, KPD, and Secret Service. We’d like to remind the public - if you see something, say something. The KCSO, working with other law enforcement professionals, will continue to stop threats to our community, and bring those responsible to prosecution."

A Walmart spokesperson did not immediately return FOX News' request for comment.
