The man who car jacked twice last spring in Mount Vernon, 55-year old David J. Pederson, formerly an inmate at the Federal Prison Camp at Marion, Illinois, was sentenced yesterday in United States District Court in Benton to a term of 5 years in prison for escaping from custody while on an unescorted transfer via bus between that facility and one in Council Bluffs, Iowa.  Pederson previously pled guilty to the escape charge on July 11, 2013.  At the time of the escape on March 26, 2013, Pederson was serving the final few months of a 71 month federal sentence for bank robbery imposed in the Southern District of Iowa.  Evidence supporting the guilty plea and sentence showed that Pederson left his authorized transfer route while at the Greyhound bus station in Mount Vernon, Illinois, and obtained a realistic looking air pistol from a retail store.  Using the air pistol, he car-jacked two separate vehicles, taking a total of four individuals hostage including two women and two children.  The first car-jacking victim was able to escape even though Pederson had bound her hands.  He was later arrested with the three hostages from the second car-jacking, a mother and her two children, in Nashville, Illinois.  On May 7, 2013, Pederson pled guilty in Jefferson County Circuit Court to charges relating to the car-jackings and was sentenced to a 20-year term of imprisonment in the Illinois Department of Corrections.   The 5-year federal sentence was imposed consecutively to the 20 year state sentence and any portion of his previous 71 month federal sentence which the Federal Bureau of Prisons determines is left to be served.  Pederson was also ordered to pay a $100 special assessment and placed on a 3 year term of supervised release to follow his incarceration.  Following sentencing, Pederson was returned to the custody of the Illinois Department of Corrections to first serve out his 20 year state sentence.  The case was investigated by the United States Marshal’s Service and the Mount Vernon Police Department.
