Dorothy Mildred Clitheroe was last seen on September 20, 1973. She was walking towards the restroom at Cortez Park at 35th Avenue and Dunlap in Phoenix, Arizona. She was wearing Levi bell bottom jeans and a white tank top with a pattern of upside down multi-colored teardrop shapes. She wore thick eyeglasses and had pierced ears but it is unknown if she was wearing any jewelry when she disappeared. She may have had the remnants of a "US Steel" scar on one of her forearms from backing into a hot radiator. It is possible only the letter "U" was still visible.
