Two men who robbed an Umpqua Bank in Grants Pass in January 2008 will each spend 10 years in federal prison.

Robert Alan Peters, 46, was sentenced in U.S. District Court in Medford on Monday and his co-defendant, Anthony George Arrigo, 56, was sentenced the previous week.

During the January 2008 robbery Peters brandished a .357-caliber revolver, fired a shot into the bank's ceiling, and yelled, "Hold up!" Peters fired a second shot into the ceiling, then ordered the tellers to place all of the money in a bag. He fled with $12,508, a Department of Justice news release reported.

Investigation by the Grants Pass police and FBI determined that Arrigo provided Peters with the gun. Arrigo also made a diversionary 9-1-1 call during the robbery, and kept most of the money stolen from the bank. Peters claimed he was desperate and needed the money for his mortgage. Peters and Arrigo were not apprehended until almost a year later, when investigators received tips that Peters and Arrigo had committed the robbery, the news release said. Peters was arrested shortly thereafter in Frazier Park, Calif., and Arrigo was arrested in Grants Pass.

Newspapers in California reported in April 2009 that Arrigo told Grants Pass police he suspected his friend Peters might have robbed the bank, then paid him part of the money as rent. Investigators then got a search warrant for Arrigo's Grants Pass home based on what Peters told them.

During their search on April 1, 2009, police found grenades, blasting caps, a gun they suspected was used in the robbery, and money, so Arrigo was arrested, a Grants Pass police news release said.

At the sentencings, U.S. District Judge Owen M. Panner ordered Peters and Arrigo to repay Umpqua Bank the amount taken.

Grants Pass police, the Federal Bureau of Investigation and the Kern County Sheriff's Department in California all worked on the investigation. Assistant U.S. Attorney Judith Harper prosecuted the case.
