• Coleman Thomas Blevins has been charged with making a terroristic threat to create public fear and serious bodily injury.
• A sheriff's office in Texas says Blevins was plotting a mass shooting at a Walmart.
• Investigators said Blevins was affiliated with extremist ideologies.

A man in Texas was arrested last week while planning a mass shooting at Walmart, the Kerr County Sheriff's Office said in a press release on Sunday.

Coleman Thomas Blevins, 28, was arrested on Friday and charged with making a "terroristic threat to create public fear and serious bodily injury."

Investigators who searched Blevin's home found "firearms, ammunition, electronic evidence, concentrated THC, and radical ideology paraphernalia, including books, flags, and handwritten documents," the Kerr County Sheriff's Office said.

The sheriff's office described Blevins, of Kerrville, as a "threat to national security."

According to the press release, sheriff's officers confirmed Blevins was affiliated with extremist ideologies and had intercepted a message on Thursday that indicated he was planning a mass shooting at a Walmart. He was taken into custody the next day.

"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 the statement. "Our investigators did outstanding work in this case, and possibly saved many lives. The plot interrupted in this case is unthinkable.

Leitha added: "We appreciate the assistance of all our law enforcement partners, including the FBI, DPS, KPD, and Secret Service."
