The nude body of a woman was discovered by some people walking on an unpaved section of Race Track Road in Oldsmar on Wednesday afternoon, said Marianne Pasha, the Pinellas County Sheriff's Office spokeswoman. Although there were "no obvious signs of trauma to the body," the death is being investigated as suspicious, she said. The body is of a white woman between 30 and 40 years old, Pasha said. She had brown hair and a medium build. No clothing or identification has been found in the immediate area, she said. "We don't know how long the body has been there, but it is not in an advanced stage of decomposition," she said. Cause of death is to be determined by autopsy by the Pinellas-Pasco Medical Examiner's office, she said.
