For most people, slipping on snow while walking to school is a fleeting memory. For Marla Waldman Conn, it became the last moment she shared with her mother, Barbara Waldman. On January 11, 1974, Barbara stood at the front door of their Oceanside, Long Island home, waving goodbye to her three children as they boarded the school bus. Marla slipped on the icy driveway; her brothers laughed. 'Marla, be careful, are you okay?' Barbara called out. Those were her final words.
Twenty minutes later, Barbara, 31, was dead. She had been sexually assaulted and murdered inside her home. The tragedy deepened when her five-year-old son Eric, returning home for lunch, discovered her body. Barbara was found upstairs with her hands bound, a pillowcase stuffed in her mouth, and a gunshot wound to the head. Police released a sketch of the suspect, but no arrest was made.
Over the decades, suspicion fell on Barbara's husband, Gerald Waldman, a dentist who was treating a patient at the time of the murder. Rumors intensified when he remarried six months later. 'My mother's side of the family always implied my father killed her,' Marla said. 'Processing that as a child was tough.' Photographs of Barbara disappeared from the walls, and discussion of the case ceased. Yet a secret box of photos remained, which Marla's brother would secretly view.
As an adult, Marla began contacting police to reopen the case, but investigators were reluctant. In 2022, serial killer Richard Cottingham, known as the 'Times Square Ripper,' confessed to several Long Island murders, including a home invasion. Marla urged police to compare DNA evidence from her mother's case. A full DNA profile was developed, but after eight months, there was no match to Cottingham or any database.
Marla persisted, pushing for FBI involvement and advanced genetic genealogy. In August 2024, a DNA match identified Thomas Generazio, a local refuse worker who lived near the Waldman home. Generazio died in 2004. 'When I was told there was a DNA match, I fell to the floor,' Marla said. 'He looked like a regular person.'
Marla investigated Generazio herself, tracking down relatives and records. One of his daughters sent a photo of him wearing a coat with a fur-lined collar, matching the police sketch. In March 2026, Nassau County police publicly named Generazio as Barbara's killer. The revelation brought relief and trauma, but knowing he was dead comforted Marla. 'When I heard he had died, that satisfied me that he couldn't hurt anyone else,' she said. 'The unknown killer is gone.' The discovery also cleared her father's name. 'It was a brutal murder. My mother deserved more than that.'
