Ohio authorities are accusing a man of forcing several women into prostitution by exploiting their drug habits. A grand jury indictment against suspect David Nelms of Columbus also accuses him of human trafficking and heroin possession. Ohio Attorney General Mike DeWine and Delaware County Prosecutor Carol O'Brien say the prostitution took place at several upscale hotels in the greater Columbus area. Investigators say Nelms advertised the women in online escort websites where he offered sexual activity for cash. They say Nelms forced the drug-addicted women to cooperate by withholding their drugs until they complied. Authorities suspect Nelms of trafficking up to a dozen women over several years. The 39-year-old Nelms remains in the Delaware County Jail.
