A convicted mail thief wanted for violating his probation shot a round from a firearm after being shocked with a stun gun today northwest of Airway Heights, according to the U.S. Marshals Service.

No one was injured and Tony L. Gust, 33, was arrested without further incident, authorities say.

Marshals were looking for Gust after a warrant was issued today in U.S. District Court. They found him at his home in the 22000 block of West Jacobs Road about 4:20 p.m. and watched as he ran into his trailer and "armed himself with a firearm," according to a news release.

"Deputies deployed a taser striking Gust. Subsequently a round was fired from the weapon Gust was holding," the news release said. "The Deputy U.S. Marshals then subdued Gust and took him into custody."

Gust was arrested in January 2011 after a postal inspector recognized him from surveillance video that showed him breaking into post office boxes at the Opportunity post office, 11712 E. Sprague Ave.

He was sentenced in June to three years of probation, but that was revoked in October and he was sent to jail for six months. He left in April and was to participate in a treatment program.

Authorities noted his "troubling history of violence and offenses involving firearms," in court documents filed in May 2011, which his lawyer attributed to Gust's "physical, mental and dependency problems" and said treatment would serve well.

Gust has previously been employed as a welder and a cook, according to court documents. In 2003, he was arrested for illegally shooting on a property in Liberty Lake, according to news archives.
