Gail Katz-Bierenbaum, 29, vanished from her Manhattan apartment on July 7, 1985. Her husband, Dr. Robert Bierenbaum, first told police she left after an argument and might have gone to Central Park. Friends and family, however, described the marriage as volatile and said Gail had confided that he was controlling and abusive. She had filed a police report in 1983 alleging he had choked her into unconsciousness, and the couple was reportedly in marriage counseling while Gail told friends she planned to leave.

Detectives found inconsistencies in Robert Bierenbaum’s account. Investigators later learned he had rented a small plane and flown for two hours over the Atlantic on the day Gail disappeared, a flight he had not mentioned initially. Authorities came to suspect he may have killed Gail, dismembered her and disposed of her remains in the ocean, but no body or physical evidence directly tying him to a crime was found. Gail’s family continued to press the case; her body has not been recovered.

Did anyone in Manhattan in July 1985 see or hear anything that could help explain what happened to Gail?
