Six middle-aged Iowa men who’re members of the “Sons of Silence” motorcycle gang are under arrest, charged with a variety of drug and weapons offenses. Jon Petersen of the federal Alcohol Tobacco and Firearms agency says the “Sons of Silence” are “one-percenters.” Petersen says the “Sons of Silence” are proud of their heritage as being the one percent of bikers who are not law-abiding citizens. Authorities accuse the group of selling pot, meth and coke. Petersen says the investigation’s been going on for a few years, and the volume of drugs involved was “significant.” The six bikers are charged with conspiracy to distribute marijuana, methamphetamine and cocaine, as well as firearms offenses. Under arrest are 50-year-old Russell John Schoenauer of Waukee, 46-year-old Robert Norman of Boone, 49-year-old Gary Lee Walker of Red Oak, 45-year-old Daniel Lee Burns of Boone, 43-year-old Barry Craig Scarcello of Boone and 55-year-old Steven Lowell Henry of Norwalk. Cops are still searching for 45-year-old Pelayo Jose Cuervo and 36-year-old William John Furlong, who face the same charges as the other six.
