U.S. District Judge Nancy Torresen imposed the unusual sentence on Travis Leeman, 30, who pleaded guilty last year to the armed bank robbery.

Leeman, who was addicted to oxycodone, robbed the bank to pay off his drug dealer after the man threatened to kill Leeman’s wife, Assistant U.S. Attorney Darcie McElwee said Monday.

Acting on a joint recommendation from the prosecutor and defense attorney, the judge went outside the federal sentencing guidelines, which recommended Leeman spend between 30 and 37 months behind bars for the robbery, in sending Leeman to prison for just one day. She did impose the minimum seven-year sentence mandated by Congress on people convicted of using a gun during a bank robbery. As a result, Leeman was sentenced to seven years and a day in federal prison.

He had been held without bail at the Cumberland County Jail since his arrest about a week after the robbery.

Torresen also sentenced Leeman to three years of supervised release after he completes his sentence. She also ordered him to pay $7,691 in restitution to the bank.

Leeman walked into Infinity Federal Credit Union on Alfred Road shortly after 9:30 a.m. May 29 wearing a yellow Carhartt-like two-piece rain suit and an orange face mask, according to the prosecution version of events to which the defendant pleaded guilty in September. He brandished an unloaded .380-caliber pistol, announced it was a robbery and demanded money before jumping over the counter.

“Once over the counter, the defendant ordered the tellers to empty the drawers, and presented a dark-colored cooler-type bag, into which $7,691 was placed,” according to the prosecution version. “The defendant then ordered the tellers to the ground and threatened that there was a partner outside, saying words to the effect of, ‘I don’t want there to be a shootout.’ The defendant then departed the credit union.”

Leeman was arrested June 3 after investigators traced the bag in which he told tellers to put the money to Walmart in Biddeford, according to the prosecution version. Store surveillance footage showed the person who bought the item get into a truck with a logo for a local business. Leeman was employed by that firm.

The global-positioning system on the truck showed Leeman briefly returned to work after the robbery, then went to pay off the drug dealer who had threatened his wife, McElwee said.

“This sentence was appropriate under the circumstances,” she said. “This was not a typical bank robbery. He had no criminal record. His addiction got the best of him and he did not seek help for it.”

Leeman faced up to 25 years in prison on the bank robbery charge and an additional mandatory minimum of seven years and a maximum sentence of life on the gun charge
