Edward and Stephania Andrews left a hotel cocktail party in Chicago on the evening of May 15, 1970, and were never seen again. Edward, 62, an accountant and semi-retired manager, had appeared ill all afternoon and at the party; witnesses later saw him staggering to a black and yellow 1969 Oldsmobile sports coupe while Stephania was crying in the passenger seat. The car struck a door exiting the Sheraton garage, needed to be repositioned, and was then observed driving the wrong way on Lower Michigan Avenue before the couple and the vehicle disappeared.

When they failed to report for work the following Monday, police found their Arlington Heights home in order but with newspapers and mail collected outside; bank and investment accounts showed no activity after their disappearance. Police initially theorized Edward may have become disoriented and driven the car into the Chicago River, but repeated sonar, dive and dragging searches turned up no trace. A 1994 informant later suggested murder and burial of the car in a Lake County pond, yet searches there were also unsuccessful. The couple was declared legally dead in 1978, but their fate remains unresolved.

Did anyone in the Chicago area in May 1970 see a black and yellow Oldsmobile after the couple left the hotel, or have other information about that night?
