Edward Martin Zajac Jr., 20, was last seen in Greenfield, Massachusetts on November 30, 1973. Later that morning his car was found abandoned on the French King Bridge, which spans the Connecticut River. His keys and wallet were inside the vehicle, a detail that suggested he had not planned to be gone long or had left in a hurry.

Police conducted searches of the Connecticut River and dragged for signs of him, but found no trace in the water or surrounding area. The bridge has been associated with suicides, which became one possible explanation, but investigators did not have evidence to reach a conclusion. Decades have passed with no significant leads reported and his family, including his sister Amelia, remains without closure.

Anyone who knew Edward’s movements on November 30, 1973, or who has information about his disappearance is asked to contact the Massachusetts State Police.
