COLUMBIA -- South Carolina deputies say a Fort Jackson drill sergeant raped a woman in his home. Richland County Sheriff Leon Lott said Friday that 33-year-old Antone Grace was charged with first-degree criminal sexual conduct after his arrest Thursday. Lott said Grace invited a woman he met on an Internet dating service to his home. The sheriff said Grace pinned the woman to his bed and forced her to have sex. She ran away as he took a shower. Lott said deputies were investigating whether Grace may have attacked other women. Phone messages left for officials at Fort Jackson were not immediately returned. Grace remained in jail on a $30,000 bond Friday evening. Jail officials didn't know if he had a lawyer.
