Not sure if this helps but they said the hair was degraded and because of this they were unable to do traditional analysis and they had to wait for science to catch up.Please, do we have anyone with Law Enforcement who is involved with using DNA for identification? It is stressed the “mitochondrial DNA" is being used. Is the mtDNA ALWAYS used this way? Why not the yDNA? As someone who knows just enough to be dangerous, I can't help wondering if mtDNA is ALWAYS used or why it is being stressed in this case.
"The hairs, found in 2010, were degraded and DNA testing at the time couldn’t yield results. But as technology progressed, mitochondrial DNA testing allowed investigators to make the connection, Tierney explained. The victims’ remains “were out in a tough environment for a prolonged period of time. So, there was not a lot of forensic evidence,” Tierney told CNN’s Anderson Cooper on Friday, and credited the FBI and one of its agents for a “phenomenal job” with extracting the evidence."
