DAVENPORT, Iowa – On June 11, 2018, Shawn Michael Manning, age 45, of Davenport, was sentenced by United States District Court Judge Stephanie M. Rose to 63 months in prison for conspiracy to manufacture marijuana announced United States Attorney Marc Krickbaum. Manning was ordered to serve four years of supervised release following his prison sentence and to pay $100 to the Crime Victims’ Fund.
On February 6, 2018, Manning pleaded guilty to the offense and admitted beginning on or about November 1, 2016, and continuing through December 26, 2016, he and other individuals reached an agreement to manufacture marijuana in a warehouse located in the 900 block of South Rolff Street in Davenport. The charge was the result of an investigation which began when Davenport Police received a tip that Manning and others were operating a marijuana grow operation at that warehouse location. On December 29, 2016, law enforcement executed a search warrant and discovered a portion of the warehouse had been walled off. Officers discovered in excess of 500 marijuana plants, marijuana derivative products and materials to assist in the manufacture and packaging for sale of the marijuana.
This matter was investigated by the Davenport Police Department and the United States Drug Enforcement Administration. The case was prosecuted by the United States Attorney’s Office for the Southern District of Iowa.
