Dail Dinwiddie: How DNA Solved a 27-Year-Old Murder

The Murder of Dail Dinwiddie

On September 24, 1992, 23-year-old Dail Dinwiddie was found dead in her apartment in Columbia, South Carolina. She had been sexually assaulted and strangled.

Dail was a young woman with her whole life ahead of her. She was a student, a daughter, a sister, a friend. Her murder devastated her family and community.

Investigators worked the case extensively, collecting evidence and interviewing potential suspects. DNA evidence was recovered from the crime scene—but in 1992, DNA technology was still in its early stages.

Despite their best efforts, the case went cold.

27 Years of Waiting

For 27 years, Dail's family lived without answers. They didn't know who killed her. They didn't know why. And they didn't know if justice would ever come.

But investigators never gave up. They preserved the evidence from Dail's case, knowing that one day, technology might advance enough to solve it.

In 2019, that day came.

The Breakthrough

Using advanced DNA technology and forensic genealogy—the same technique used to catch the Golden State Killer—investigators were able to create a genetic profile from the DNA evidence collected in 1992.

They uploaded the profile to genealogy databases and began building a family tree. Through painstaking research, they narrowed down potential suspects.

The DNA led them to Zachary Bunner.

Bunner had been living freely for nearly three decades. He had never been a suspect in Dail's murder. But the DNA didn't lie.

Arrest and Conviction

In 2019, Zachary Bunner was arrested and charged with Dail Dinwiddie's murder.

In 2023—31 years after Dail was killed—Bunner was convicted and sentenced to life in prison.

Dail's family finally had the justice they had been waiting for.

The Power of DNA and Persistence

Dail Dinwiddie's case is a powerful example of how forensic genealogy and advances in DNA technology are solving cold cases that were once thought unsolvable.

It's also a testament to the dedication of investigators who never gave up on Dail. They preserved evidence. They kept her case active. They waited for technology to catch up.

And when it did, they were ready.

Remembering Dail

Dail Dinwiddie was 23 years old when she was murdered. She should have had a long, full life ahead of her.

Instead, her life was stolen by Zachary Bunner—a man who thought he had gotten away with murder.

But Dail was not forgotten. Her family never stopped fighting for her. Investigators never stopped working her case.

And after 27 years, justice was finally served.

Dail Dinwiddie's case reminds us that it's never too late for justice. Cold cases can be solved. Killers can be caught. And families can finally get the answers they deserve.
