AUSTIN – According to a FBI court filing, a Christian Terrorist Suspect who agents recently arrested exhibited “sovereign citizen extremism” and was planning a mass shooting.

A criminal complaint filed in federal court says 50-year-old Steven Boehle is facing charges that include unlawful possession of a firearm by a prohibited person.

Records show the Austin man was found in possession of firearms and hundreds of rounds of ammunition.

Boehle on several occasions had attempted to purchase more but was denied because of a 1993 domestic-violence conviction in Connecticut. Authorities say he also made false statements in an effort to buy weapons.

An arrest warrant filed Monday revealed he was taken into custody April 12.
