Mary Michelle Sprague, 19, vanished from Daytona Beach, Florida, after leaving a nightclub in the 300 block of Madison Avenue on the night of September 11, 1979. She had gone to the club that evening to pick up her paycheck and have a few drinks, and left around 1:00 a.m. after an argument with her boss. A cab driver later said the cab had to evade a truck that seemed to be following them as they left the club. Mary never was seen again after that night.

At the time she disappeared Mary worked as an exotic dancer and was a mother to a young son; her family felt she would not have voluntarily left him behind, which contributed to suspicions of foul play. Her son was later adopted by another family and has since died. Many close relatives, including her mother, are also deceased, and investigators report no significant leads.

Does anyone who lived or worked near Madison Avenue in Daytona Beach in 1979 remember seeing Mary that night or notice a truck following a taxi?
