More than five decades after a young Oceanside mother was sexually assaulted and shot to death in her home, Nassau County police unveiled Wednesday that advances in DNA technology have identified the man allegedly responsible for the gruesome crime.
Police Commissioner Patrick Ryder said at a news conference on March 11, investigators used investigative genetic genealogy and FBI resources to identify Thomas Generazio as the alleged attacker in the killing of Barbara Waldman.
Waldman, 31, was found dead in her Oceanside home on Jan. 11, 1974, lying face down with her hands bound behind her back. Police said she had been strangled with her stockings following a violent sexual assault.
“This individual committed a violent sexual assault against a mother and then put a bullet in her head,” Ryder said. “The animal that he was that day taking that mother from her three children is inexcusable.”
Waldman’s children, Eric, Larry and Marla, were just 5, 6 and 7 when their mother was killed. They stood alongside detectives, recalling decades of grief and the long search for answers.
For years, the case remained unsolved despite early investigative work, including a sketch closely resembling the suspect.
“The sketch was almost a perfect match to the subject, but back then, DNA wasn’t tested,” Ryder said.
DNA testing didn’t become standard until 1996, and by 1998, the CODIS system allowed all collected DNA in Nassau County to enter a database. However, if someone wasn’t already in the system, and Generazio wasn’t, they could not be identified.
The breakthrough came in August 2024, when investigators used investigative genetic genealogy, comparing crime scene DNA with genealogical databases with FBI assistance. This process eventually led detectives to Generazio, who had not previously been identified as a suspect.
Police said Generazio had two prior arrests. One for assault and one for stolen property, but otherwise lived a relatively ordinary life as an Oceanside sanitation worker.
“He had two prior arrests, but there was no way to catch him in that DNA system,” Ryder said.
Unfortunately, Generazio died at age 57 in 2004 from cancer before he could face justice.
“We would have liked to have seen him in jail for that entire time for the brutal murder that he did,” Ryder said.
Waldman’s children felt both relief and renewed grief. Marla said she was stunned the suspect had lived so close to the family.
“I was dumbfounded,” she said. “He looked like a normal guy, and he lived just 3.7 miles from us.”
Her brother Larry called the revelation long overdue and noted that it also cleared the name of their father, who had been a suspect for decades.
“This is vindication for my father, it’s a bittersweet day,” he said.
Eric Waldman thanked detectives and reflected on the lasting impact of losing his mother.
“I’ve had the image of my mom in my head since I was five,” he said. “It doesn’t give me complete closure — my mother’s not here,” he said.
Still, Marla said the identification provides some measure of relief.
“Although this won’t bring our mother back, it allows us some peace,” she said.
