The sheriff heading the investigation into a body found on North Carolina's Outer Banks says detectives need help from medical examiners to determine if the corpse is that of a missing Ohio woman. Dare County Sheriff Doug Doughtie said Sunday an autopsy could be done as early as Monday, a step he says is needed to identify the body found about 20 to 30 miles from where 33-year-old Lynn Jackenheimer, of Ashland, Ohio, disappeared. Sheriff's investigators were unable to tell if the body is a woman or a man. Jackenheimer was reported missing when she didn't come home from a vacation on the Outer Banks with her two children and her on-and-off boyfriend, Nate Summerfield. Police say Summerfield dropped the children off in Ashland and drove away.
