Last week Tuesday, Mark Anthony Samual Berkebill, 60, of Marinette was charged with controlled substance violation and failure to affix a drug stamp. The incident began about 4:15 a.m. Friday on eastbound U.S. Interstate 80 near the Grand Prairie Parkway exit in Waukee, Iowa where an officer of the Waukee Police Department conducted a traffic stop on a 2021 Toyota Camry that was allegedly “following a pickup too closely,” according to court documents.  The officer made contact with the driver, Berkebill, whom the officer soon suspected of “being deceptive in his travel plans, including when he left his home for his destination when he left his destination, and how long he had been at this location,” according to court documents. Berkebill’s admission to the officer that there was “a THC vape pen in the door of his vehicle” prompted a probable-cause search of the vehicle, which disclosed “30.428 pounds of marijuana in two separate duffle bags in the vehicle’s trunk,” according to court documents. Berkebill is being held in the Dallas County Jail on a $10,000 cash or surety bond. He is scheduled for a preliminary hearing, on January 24th in the Dallas County District Court.
