Carmen Marie Hallock, 22, was last heard from in Fort Lauderdale on December 18, 1969. A white woman with brown hair and brown eyes, she was about 5 feet 5 inches and 120 pounds. On the evening she vanished she told her sister‑in‑law she had an appointment with a male junior‑college teacher who claimed to do undercover government work and had promised a job that included international travel and a high salary.

Hallock bought a black cocktail dress and black patent‑leather pumps for the meeting; neither garment was ever recovered. When family checked her apartment after she missed Christmas contact they found the bathtub filled with water, her dog unfed, and her car keys, driver’s license and vehicle registration gone. A few days later her car was found abandoned in a nearby parking lot but there was no sign of her.

In April 1973 two gold‑filled teeth and a gold shamrock pin belonging to Hallock were found among the belongings of Gerard John Schaefer Jr., a former Florida law‑enforcement officer and intern teacher in the Fort Lauderdale area in 1969. Authorities have long suspected Schaefer in several disappearance cases from that period; no charge was ever filed in Hallock’s disappearance and no verified remains or definitive forensic evidence have been found. Does anyone have information on Hallock’s contacts in Fort Lauderdale in December 1969 or recall seeing the car after December 18?
