Joanne Williams was 22 when she disappeared from Scranton, Pennsylvania, in December 1978. On the evening she vanished she left her East Gibson Street residence to attend an exercise class at a dance school in Chinchilla, driving a distinctive red 1977 Datsun 200 SX with white racing stripes. The last reported sighting was at about 10:00 PM at the dance school on Route 6; she wore a leotard top, blue jeans, and a beige tweed jacket.

Nine days later, on December 16, 1978, Joanne’s Datsun was found parked at Lafayette Street and North Everett Avenue in West Scranton, less than a mile from her home. The car was unlocked and contained her purse and paycheck; there were no signs of a struggle and no clear explanation for her disappearance. She was legally declared dead in 1991, but investigators have never tied the case to anyone conclusively. A man named Frank Osellanie was at one point a person of interest in other crimes and denied involvement; no definitive link to Joanne has been established.

Does anyone from Scranton or Chinchilla at the time remember seeing Joanne, her red Datsun, or anything unusual near Lafayette and North Everett Avenue in December 1978?
