A California man has been sentenced to ten years in prison after pleading guilty to a drug charge.  According to a statement from United States Attorney Nicholas Klinefeldt, 68 year old Gerhard Jacobus Hanneman of Fort Bragg, California was sentenced Friday in United States District Court.  He had pled guilty on conspiracy to manufacture and distribute marijuana.

From February 2011 to December 2011, Hanneman grew marijuana in California.  His marijuana grow operation took place inside buildings or on outside property controlled by him.  Hanneman then processed and drove this marijuana from California to Iowa for redistribution by co-defendants Andrew Gallagher and Joseph Haynes.

During the course of this conspiracy, Hanneman manufactured and distributed in excess of 100 kilograms of marijuana.  He was also placed on four years of supervised release and ordered to pay $100 toward the Crimes Victims Fund.  This is the second sentencing after 26 year old Haynes of Fairfield was ordered to spend 78 months in prison and four years on probation for the same charge last month.  Gallagher is awaiting sentencing.

The case was investigated by the Iowa Department of Public Safety, Division of Narcotics Enforcement, the Coralville PD, the Fairfield PD, the Iowa City PD, the Ottumwa PD, the University of Iowa PD, the Johnson County Sheriff’s Office and the Washington County Sheriff’s Office.
