Cold Case Breakthrough: DNA Links Ohio Man to 1989 Rape
Cincinnati, OH - After more then three decades, a chilling cold case has taken a dramatic turn. the FBI has arrested a 62-year-old Ohio man in connection with the brutal 1989 rape of a woman in her Cincinnati condominium.The arrest comes after DNA evidence, recently re-examined using advanced technology, linked David Tanzer to the crime scene.
The attack, which occurred on August 12, 1989, left the victim traumatized and desperate for justice. According to court documents, the woman was bound, gagged, and sexually assaulted for over five hours in her Columbia tusculum home.
“The attacker put a cloth in my mouth and only agreed to take it out when I told him I wouldn’t scream,” the woman recounted to investigators at the time.
During the ordeal, the assailant wiped semen from her body, further adding to the horror of the experience.
The woman managed to get a glimpse of her attacker through the tape covering her eyes. She described him as a white male, approximately 6 feet tall, thin, with dark brown hair – a description that aligns with Tanzer.
eventually, the attacker loosened the bindings on one of the woman’s hands and left. She managed to free herself and sought help from a neighbor, who called 911.
Investigators found a chilling message scrawled on a torn piece of newspaper taped to the bedroom phone: “No police or I’ll be back Mis IBM.”

For years, the woman remained persistent to see her attacker brought to justice. She stayed in contact with police, hired private investigators, and even participated in media interviews, hoping to generate leads.
On Wednesday, when questioned by the FBI, Tanzer denied any involvement in the attack. However, after being handcuffed, he reportedly told someone in his home: “We’ve got to find a great lawyer. I don’t know what’s going on.”
The FBI is urging anyone with facts about the 1989 attack or any other similar incidents to come forward. They can be reached at 1-800-CALL-FBI.
