1 Hair. 10 Years. Case Closed. — A single human hair recovered from a 2003 Washington State crime scene sat untested for over a decade before mitochondrial DNA analysis finally identified a suspect. This video breaks down how forensic hair analysis evolved, why labs couldn't process it in 2003, and what changed by 2014 when the case broke open. Discover how mitochondrial DNA works differently from nuclear DNA — and why it can survive when standard samples can't.
