Martin was a recent graduate of the Wilkes-Barre Business College. On December 17, 1938, she met an unknown man who claimed to be offering her a secretarial job, and was never seen alive again. Her body was discovered in the wilderness 25 miles (40 km) away by a hunter four days later. Martin's death resulted in a lengthy manhunt.
