Behavioral problems continue to plague the men accused of selling the gun used in the Trolley Square massacre.

After being sentenced to one-year of probation for his role in the gun sale, Matthew Hautala was back in federal court Wednesday for violating the terms of his probation after he was charged in Wyoming for an array of state and federal crimes, including dealing LSD and cocaine.

It was almost a year ago that a 20-year-old Hautala, freshly inducted into the U.S. Army, tried to impress the court with his clean-cut image and rigid discipline. For his role in the sale in which Sulejman Talovic bought the .38 Special revolver for $800, Hautala was spared prison time and given probation as a chance to get his life back on track.

Hautala violated the court's trust while the "whole world was watching," said Assistant U.S. Attorney John Huber. Just days before he appeared in federal court and accepted a plea deal, Huber said Hautala had been arrested on suspicion of drug dealing.

U.S. District Judge Dale Kimball noted that Hautala is facing federal counts of dealing LSD and cocaine out of Wyoming as well as facing state charges there for theft and burglary.

On Wednesday, Kimball sentenced Hautala to serve nine months in federal prison before sending him to Wyoming to face the pending charges there.

Hautala is not the only one who has violated terms of his probation. In March, Brenden Taylor Brown was ordered to serve two months in jail for violating the conditions of his one-year probation sentence. Brown was accused of failing to follow the court's orders to take drug tests and report to a probation officer.

Another man charged with selling the massacre gun, Mckenzie Hunter, was ordered held in federal custody pending his case after a federal magistrate found him uncooperative with the court's supervisors and he tested positive for marijuana. The court noted Hunter appeared too busy texting his friends on his cell phone to cooperate with an interview with a court official.

Hunter was sentenced to 15 months in federal prison. During his sentencing in January, Hunter said he traded the gun for a bag of cocaine in Rock Springs, Wyo., before selling the gun to Talovic.

Talovic used the gun in the Feb. 12, 2007, mall shooting which left five people dead and four wounded.

All three men said the did not know the gun was going to be used for such a horrific crime.
