Four southwest Iowa people were arrested Tuesday on drug charges in Fremont County. The Sheriff’s Office says the residents of a Hamburg apartment, 40-year old Randall Larson and 22-year old Samantha Hull, along with 39-year old Adam Blackman, of Malvern, and 35-year old Clinton Robinson, of Hamburg, were taken into custody following the execution of a search warrant at 409 F Street, in Hamburg. Authorities say after an active methamphetamine lab was found in the apartment during their search, agents with the Iowa Department of Narcotics Enforcement processed the scene to secure the evidence, and remove hazardous materials.

Each of the four suspects were charged with Conspiracy to Manufacture 5 grams or more of Meth. They were being held in the Fremont County Jail on $100,000 bond each. Officials say additional charges are expected, as their investigation remains ongoing.
