A Pennsylvania man has been sentenced to 21 years in federal prison for robbing a Whiteford bank in 2015, telling investigators afterward he needed the money to pay restitution owned from a prior robbery conviction.The sentencing of Jesse Allen Burney, 34, of Harrisburg, Pa., for armed bank robbery took place Friday in U.S. District Court in Baltimore before U.S. District Judge Ellen L. Hollander, according to Maryland U.S. Attorney Rod Rosenstein.Burney pleaded guilty in July to armed robbery of the PNC Bank, in the 2400 block of Whiteford Road, on April 27, 2015. The plea agreement stipulated prosecutors would recommend the 21-year prison sentence.At the time of the robbery, Burney was under supervised release from a 2005 bank robbery conviction in Pennsylvania for which he received a 12 year federal sentence. He had been released on May 30, 2014, according to court records and federal prosecutors.According to his plea agreement in the Whiteford robbery, Burney entered the bank in wearing a motorcycle helmet with the reflective visor down, a tactical vest, gloves and a backpack. An AK-47, with a sock over the barrel, was poking out the top of the backpack.Shortly after entering the bank, Burney withdrew a Taser, turned it on, pointed it at the tellers and demanded $100,000. Burney threatened to start shooting if the safe was not opened in 15 seconds, according to the statement of facts in the plea agreement.The tellers gave Burney money from the bank's vault. He put $97,237 in his backpack and, as he walked out of the bank, Burney told the employees that he would come back and shoot them if he saw any police, prosecutors said,Burney fled on a dirt bike. Several miles away, he left the bike on a country road hidden under a tarp. He drove away in an black Kia SUV that he had left at that location and which was registered to his mother, police said at the time.Law enforcement officers were able to track Burney as he drove into a farm field in Lower Chanceford Township, Pa., near Airville, via a GPS device that had been placed with the stolen money. Burney then ran from the SUV and hid in the woods, about 11 miles north of the robbery scene.A Pennsylvania State Police trooper found Burney in the woods. Investigators recovered a loaded AK-47 magazine in the backpack, as well as the AK-47 which had a loaded 30-round magazine attached and a round in the chamber. The stolen money was also recovered, along with the helmet and tactical vest Burney wore during the robbery.Burney told investigators that he owed $100,000 in restitution for the prior federal bank robbery conviction, prosecutors said.Rosenstein commended the FBI, Pennsylvania State Police and Harford County Sheriff's Office for their work in the investigation. Assistant U.S. Attorney Aaron S.J. Zelinsky prosecuted the case.
