On Jan. 11, 1974, Barbara Waldman was found murdered in her Oceanside, New York home. The 31-year-old woman lived with her husband, who was a dentist, and three young children in a Colonial style home in the 3900 block of Sally Lane in Oceanside, a hamlet on Long Island. One of Barbara's young sons found his mother on the second floor of the family's home when he got home from kindergarten.
The Nassau County Police Department responded and began investigating the case as a homicide. Barbara Waldman was lying next to her bed wearing a nightgown and bathrobe and her hands were tied behind her back with a pair of pantyhose. She had been shot once in the head. The house had not been ransacked and when detectives questioned neighbors, they had not seen anyone enter the two‐story house. Investigators learned that Waldman, a vibrant woman with long blonde hair, was well-liked in the neighborhood and was active in the Oceanside Cancer Society unit.
A composite sketch for the suspect was created and released to the public during the investigation. Over the years, investigators ruled out several potential suspects, including serial killers. Despite the extensive efforts of investigators, no suspect was identified and the case was cold for decades.
In 2024, investigators teamed with Othram to leverage its identity inference process, which enables investigators to identify individuals from DNA evidence, even when there is no known reference sample to initially compare against. Officials with the Nassau County Police Department, the Nassau County District Attorney's Office, and the Nassau County Office of the Medical Examiner worked together to submit forensic evidence to Othram's laboratory headquartered in The Woodlands, Texas.
At Othram, scientists reviewed details of the case, determining that advanced DNA testing could help to identify the suspect. Othram scientists used Forensic-Grade Genome Sequencing to build a comprehensive DNA profile for the suspect. This DNA profile was delivered to the FBI's forensic genetic genealogy team, allowing them to generate new investigative leads in the case.
Investigators have now identified Thomas Generazio as the person responsible for Barbara Waldman’s murder. Generazio lived a few blocks away from the Waldman home and worked as a sanitation worker man. He died in 2004.
This case is a reminder that every piece of preserved evidence has the potential to unlock long-awaited answers. If you’d like to support efforts to solve more cases like Barbara’s, consider contributing your DNA data to the DNASolves database which aids law enforcement in identifying suspects and giving families the answers they deserve. This is the 19th publicly announced case in the State of New York where officials leveraged Othram’s identity inference pipeline. Explore other cases on Othram’s website.
