Police in Cobb County Georgia have arrested 20 suspects in the rape of a 13-year-old mentally disabled girl that occurred on October 13-14. Police report that the girl was repeatedly raped for several hours over the course of two days at two apartments in Forest Creek Crossing in South Cobb. Blood samples from the girl provided sufficient evidence against 20 suspects in the case, including Raphael Alberto Joseph, 22, who surrendered to police on November 28 and is being held without bail facing charges of rape and aggravated child molestation. Two defendants, 12- and 13-year-old brothers, pleaded guilty to charges of child molestation early in November but were charged only with two years probation in exchange for testimony against other defendants in the case. Additional hearings have been scheduled for Isaac Cummings, 17; Joseph Jimmy Johnson, 25; Keland Taiwan Ware, 19; Shimmel Antwan Nicholson, 18; Carelius DeMarco Davidson, 19; James Davidson, 27; and two 16-year-old boys. Taurean Maurice Green, 17, awaits a hearing date, and 8 other defendants will plead their case before a grand jury.
