A 21-year-old man has been found guilty of two counts of sexual assault in a December 2016 gang rape of 13-year-old girl. Jacolby Hasan Williams, the oldest of six males initially charged in the attack,initially denied he was present when the girl was raped. Prosecutors Christina Perroni and Oliver Robinson said evidence proved otherwise, as the defendant's DNA and apparent semen were found on her jeans, consistent with her report that he had ejaculated on her leg. The nine-woman, three-man jury deliberated for three days before reaching the verdict late Monday afternoon.
