An Adams County jury has found a former paving company executive guilty of 62 felonies in a government corruption case that was first exposed in a CALL7 Investigation.After a three-week trial, jurors found Dennis Coen, the former president of Quality Paving and Quality Resurfacing companies, guilty on 20 counts of theft, 19 counts of conspiracy to commit theft, 21 counts of forgery and two counts of attempt to influence a public servant. The jury also found Coen not guilty on seven charges.Coen, 58, ran the day-to-day operations of paving companies when the contractor received millions of dollars of no-bid contracts from Adams County Public Works to resurface roads in the northeast suburban area.In 2008, CALL7 Investigators raised questions about the no bid contracts, apparent gifts and work on county employees' homes provided by Quality Paving. Those stories sparked an investigation that led to charges against Coen and six others.In the spring of 2008, the Adams County sheriff and district attorney launched an investigation into allegations of improper and illegal transactions between employees of Adams County Public Works and county road contractors, Quality Paving and Quality Resurfacing, said Krista Flannigan, spokeswoman for Adams County District Attorney Don Quick.Over the last three years, the investigation involved the collection and review of more than 80,000 pages of documents, interviews of factual and expert witnesses and detailed examinations of numerous county road construction projects.Quick and Adams County Sheriff Douglas Darr declined comment on the case Wednesday, pending Coen's sentencing on April 12. However, they did thank the jury for their time and attention and thanked sheriff detectives Jeremy Whytock, Terry Miles, and prosecutors Dave Young and Jess Redman for their efforts on the case.A former county employee and former Quality Paving employee have pleaded guilty in the case, and one Quality Paving employee was acquitted.Lee Asay, the former director of Adams County Public Works, his deputy, Sam Gomez, and Quality Paving owner Jerry Rhea were also charged in the case. Their trial dates have yet to be set.
