Yeah, why I am convinced it's an unsub (unknown subject) - any person already in the criminal justice system would have been matched to this case by now.
Evidence in ‘29 Stalker’ to get new look
A 2007 investigative report by The Free Lance–Star noted that nuclear DNA found with Reynolds’ remains was a candidate for updated analysis.
Paul Ferrara, who was then the director of Virginia’s labs, recommended that testing be done.
In addition, forensic scientists now frequently have success in finding what’s referred to as “touch DNA” in cold cases.
Touch DNA, as the term suggests, is DNA left behind after someone grabs something.
When DNA analysis was in its infancy, scientists needed a large sample of biological material—at least the size of a silver dollar—to produce a DNA profile. Today, a profile can be produced from as little as a few hundred cells—or what would fit on the head of a pin.
It’s even possible to lift it from a fingerprint, experts say.
Detectives obtained fingerprints from evidence in the case, including Reynolds’ car and items from her wallet, located before her body was found.
