Autopsy results reveal a new clue in the death of a man who was found dead Wednesday at a motel in Clarion. Officials say the victim is an Hispanic man in his late 20s or early 30s. Preliminary autospy results suggest the man was strangled. Authorities are searching for a G-M-C or Chevrolet conversion van painted light blue, light gray and white. The van, which has a Kentucky license plate, may have been used by people who have information important to the case.
