An Evansville man told police that little girls sexually arouse him. That's why he exposed himself to a 6 year-old girl when she got off her school bus on Savannah Drive this afternoon. According to the probable cause affidavit, 20 year-old Brian Williamson not only admitted to exposing himself to little girls on several other occasions, he also admitted that he molested two 3 year-olds in separate incidents. Police will wait until they interview the victims before they file charges in those chases. Right now, Williamson is charged with preforming sexual conduct in the presence of a minor.
