2 days agoIdentification of bones unravels heartbreaking case of California teen
DNA testing identified a teenage boy found in 1993 as Joseph Patrick Reardon, but investigators still do not know how he ended up alone and dead.
The strategy could be fruitful: If unidentified DNA evidence can be connected to someone - even a distant relative - in a common genealogy database, it would give investigators more information and possibly lead to a suspect in Guthrie's kidnapping in Arizona. "It's a fantastic tool," said Ruth Ballard, a geneticist in California who specializes in DNA and has testified in hundreds of court cases. "If it's a good quality sample and they're able to get a profile, they could find a hit on that fairly quickly."
His arrest comes more than two decades after three men, who had been imprisoned for more than 17 years for the crime, were released after advanced DNA techniques showed no link between them and DNA from a vaginal swab of the victim. One of the then-suspects, John Kogut, had given police a confession to the murder that he later recanted.
