DES MOINES, Iowa (AP) — The president of an Iowa ready-mix concrete company has pleaded guilty in a price fixing case.
The Justice Department says Chad Van Zee pleaded guilty on Monday in U.S District Court in Sioux City, and agreed to cooperate with the department's ongoing antitrust investigation.
Van Zee was accused of participating in a conspiracy to fix prices for sales of ready-mix concrete from 2006 to 2009. The Justice Department said Van Zee's company was located in Rock Valley, but it did not identify the company.
Van Zee is the third person to plead guilty in the investigation in Iowa and surrounding states.
Steven VandeBrake, a former executive of another ready-mix concrete company, and Kent Stewart, the president of another Iowa company, pleaded guilty in May.
