Sharon Zelinski McCully, 25, of Austin, Texas, was last seen on December 11, 1984, after a day of Christmas shopping and lunch with her husband. She dropped him at work about 1:40 p.m. and was driving an off-white 1965 Volkswagen Beetle with a distinctive orange hood and no front bumper.

Two days later the Beetle was found abandoned at an apartment complex on Research Boulevard, about five miles from where she was last seen. The car was unlocked; McCully’s purse with $170 and her keys were missing. Investigators found no obvious signs of a struggle inside the vehicle, though a few partial fingerprints were recovered. A reported sighting of McCully with a man near the complex was never fully confirmed. Her husband passed a polygraph and said their marriage was happy.

Authorities have long suspected foul play and believe she may have been taken against her will, but no strong leads have emerged and the case is unsolved. If anyone knew Sharon, her routines, or saw her Beetle in mid-December 1984, please share what was observed or any information that might help.
