A sunny Gulf Coast day can hide the darkest secrets. We kick off with light banter about warm holidays and beach-town charm, then turn to a haunting case from New Year’s Day, 1985: 23-year-old mother Tonya McKinley leaves a Pensacola bar and is found hours later, assaulted and strangled. Investigators collected semen and blood at the scene, interviewed witnesses, and chased every lead, but the limits of 1980s DNA and disconnected databases let the trail go cold. For decades, Tonya’s family lived with a name-shaped void.
Everything changes when genetic genealogy enters the picture. We unpack how detectives partnered with Parabon NanoLabs to build a family tree from crime scene DNA, narrowed possible relatives, and focused on men who lived nearby in 1985. A discarded cigarette butt from Milton resident Daniel Wells provided the crucial match in 2020, aligning with the original forensic profile and ending 35 years of uncertainty. We explore the steps behind the scenes—surveillance for touch DNA, laboratory confirmation, and the decision to share his profile with other agencies to probe possible links.
Then comes the emotional whiplash. Wells is arrested and reportedly admits involvement, but he dies by suicide in jail before facing trial. We wrestle with the complex feelings that follow: gratitude for the science that named a killer, anger at the loss of courtroom truth, and empathy for a son who grew up without a mother or a full story. Along the way, we tackle the ethics of using consumer DNA databases for law enforcement, balancing privacy with the power to solve cold cases and deliver overdue accountability.
