Reuters 2 minute read A man suspected of planning a mass shooting was arrested in Texas after authorities intercepted a message that indicated he was "preparing to proceed", the Kerr County Sheriff's Office (KCSO) said in a statement on Sunday. Coleman Thomas Blevins, 28, made a specific threat to target a local Walmart store, KCSO said in the statement posted on Facebook. The Sheriff's Office posted an image of evidence apparently collected from Belvins' apartment that showed a rifle with multiple magazines, a flag with Nazi party symbols and the national flag of Saudi Arabia. Books and hand-written documents were also seized by investigators.
