CLINTON — A Clinton man has been sentenced to seven years in federal prison for possessing a firearm as a felon.

Ryan J. Duncan, who earlier pleaded guilty to two counts of that charge, was sentenced Wednesday in federal court in Davenport. Duncan, 25, also was ordered to serve a three-year term of supervised release after he completes his prison stay and pay $200 to the crime victims reparations fund, according to a release from the U.S. Department of Justice.

The charges were the result of two incidents, one in February 2005 and the other occurring two months later.

On Feb. 12, 2005, Duncan was driving a vehicle that was pulled over by a Camanche police officer who issued Duncan citations for speeding and driving under suspension. The officer called for a tow truck to respond and informed Duncan his vehicle was going to be towed, authorities have stated. At that time, a second vehicle driven by a female arrived and pulled up behind the officer’s squad car.

Duncan asked to wait in the second car. Officers agreed, but told him to remain at the scene. As officers searched Duncan’s vehicle, the second car, with Duncan in it, drove away.

Inside his vehicle, officers found several items, including a loaded magazine and a Chinese SKS rifle with folded bayonet and scope. Officers were unable to locate Duncan and a warrant was issued for his arrest.

On April 28, 2005, officers received a call that shots had been fired in Clinton. When officers arrived, they met with four witnesses who pointed out a spent 9-mm cartridge and an unfired round on the street.

The four witnesses described a vehicle that drove by on two occasions. They said the occupants drove by the first time and yelled and the second time, a rear passenger sitting in the passenger side of the vehicle waved a silver-colored handgun.

That backseat passenger, later identified as Duncan, was said to have cocked the handgun by moving the slide and then fired one round into the air. The vehicle then left.

Officers later found that vehicle at a Clinton residence. Three people came out of the residence, but refused to say if Duncan was inside. That’s when a standoff with police began; Duncan was taken into custody after he tried to escape out the back porch door at the residence.

The case was prosecuted by the U.S. Attorney’s Office in the Southern District of Iowa. The investigation was conducted by the Bureau of Alcohol, Tobacco and Firearms, the Camanche and Clinton police departments, the Clinton County Sheriff’s Office and the Clinton County Attorney’s Office.
