Jeanne Scrima, 44, vanished on March 19, 1980, while driving from Erie, Pennsylvania, back to her home in Knox, New York. She had been staying in Erie with her boyfriend, John Sidney, and intended to return to meet her estranged husband, John Scrima, and see her attorney later that day. Jeanne never arrived for the appointment and was not reported missing until May 4, 1980, when her attorney contacted police.

Months after her disappearance a light blue 1977 Lincoln Continental registered to Jeanne was located in Michigan; investigators say the vehicle passed through multiple owners before being found, and no trace of Jeanne turned up. Her boyfriend cooperated with investigators and took a polygraph; her husband declined to speak and retained an attorney soon after the missing person report was filed. Foul play is suspected but no arrests have been announced and Jeanne has never been found.

What information might help fill the gap between Jeanne’s departure from Erie and the discovery of her car in Michigan?
