A 37-year-old Clinton man was sentenced Friday in U.S. District Court, Davenport, after being convicted of multiple drug and gun offenses.

U.S. District Judge John Jarvey sentenced Kendall D. Robinson to 30 years in prison and 10 years of supervised release.

Robinson was indicted in August 2011 for conspiracy to distribute more than 280 grams of crack cocaine from 2008 to 2011, possession of a firearm in furtherance of the conspiracy and being a felon in possession of firearms.

The conspiracy involved several individuals who distributed crack together in Clinton for nearly three years. At least two firearms were linked directly to Robinson.

Robinson was found guilty on all charges in July. The government presented testimony from more than 46 witnesses during the six-day trial, included two co-defendants, Carley Campbell Sr. and Terrance Campbell, who pleaded guilty before trial.

One witness testified that she was with Robinson when he shot a vehicle and another witness testified Robinson’s gun was discovered in the witness’ apartment, according to court records.

In his order Thursday denying a motion for a new trial, Jarvey wrote that Robinson “was engaged in extensive drug activities over a long period of time.”
