Iowa County authorities have charged a 19-year-old man with second-degree reckless homicide in a March fatal shooting. Austin Valdez was arrested Monday. Ridgeway police say they found the body of 46-year-old Robin Reeson when they responded to a call early on the 24th. Forty-three-year-old Melanie Reeson was home at the time and Valdez is her son. He is scheduled to make his initial court appearance Wednesday in Iowa County.
