KERRVILLE, Texas — Kerr County Sheriff’s officers have charged a man accused of plotting to carry out a mass shooting at a Walmart. 

A search of the suspect’s home turned up firearms, ammunition and materials officials described as “radical ideology paraphernalia.”

Coleman Thomas Blevins, 28, was arrested Friday in Kerrville and has been charged with making a “terroristic threat to create public fear of serious bodily injury,” the Kerr County Sheriff’s Office said in a weekend news release.

Investigators said they intercepted a message from Blevins on Thursday indicating he was “preparing to proceed with a mass shooting,” and that the threat included Walmart. Blevins was taken into custody the next day.

Authorities searched his home and seized “firearms, ammunition, electronic evidence, concentrated THC, and radical ideology paraphernalia, including books, flags, and handwritten documents,” according to the release. 

Blevins is on felony probation and was not authorized to have guns, the release said. He was booked into the Kerr County Jail in Kerrville, 70 miles northwest of San Antonio.
