DARLINGTON - A Darlington man was charged Monday with sexually assaulting an underage girl earlier this month. David Ross Blench, 22, was charged with a Class C felony count of second-degree sexual assault of a child and a Class I felony count of exposing his genitals to a child. The charges stem from an incident on April 11, when Blench allegedly fondled the girl's breasts and attempted to convince her to perform sex acts.
