How Fitness Trackers Are Solving Murders with Nancy Grace and Dr. Oz | Oz True Crime

Fitness trackers are now showing up as evidence in murder cases, and Dr. Oz and legal analyst Nancy Grace go through how it works.

They break down real true crime cases where data from a wearable changed the investigation. Heart rate spikes, step counts and sleep logs exposed crime scenes that had been staged, contradicted a suspect’s alibi, and in some cases helped clear people who were innocent. Grace explains why this kind of digital evidence holds up in court and what investigators look for when they pull it.

Kelly Herron also joins the show. She was attacked while out on a run and fought her attacker off. Her fitness tracker kept recording through the whole thing and logged about eight minutes of struggle along with her heart rate surging. She talks about what happened and what it was like to see that moment in her data afterward.
