A Lake Geneva man accused of selling Viagra to an undercover sheriff's deputy was found guilty Friday of three misdemeanor counts of a dispensing prescription drugs. David L. Vos, 55, of 617 Haskins St., Lake Geneva, originally was charged with three counts of felony delivery of prescription drugs, but the charges were reduced in a plea agreement. "The misdemeanor charges, I felt, captured the nature of his conduct," said Deputy District Attorney Joshua Grube. "Part of the agreement, too, is to look at the drug that's being delivered. This isn't a drug that's out there killing people like heroin is and cocaine is." Vos must serve 90 days in jail and pay $100 plus court costs. According to the criminal complaint, an undercover Walworth County deputy met with a man July 26, 2007, at a home on Krueger Road in Geneva Township. The deputy gave the man $80 in exchange for Viagra pills, the prescription information and the doctor's name, according to the complaint. The deputy met with the man again Sept. 17, 2007, to buy more Viagra, but the man couldn't get the drug because he had given his prescription to the deputy, according to the complaint. Instead, the man sold the deputy 12 pills from his prescription for Vardenafil (Levitra)a drug similar to Viagra. The deputy met with the man a third time Nov. 30, 2007, at a gas station in Lake Geneva and bought eight pills of Viagra for $80, according to the complaint.
