Guthrie Investigators Turn To DNA Genealogy Databases

Authorities trying to solve the disappearance of Nancy Guthrie say they might tap DNA genealogy databases. It's the same step that police took to unravel a series of murders in California and the fatal stabbings of four college students in Idaho. The strategy could pay off: If unknown DNA evidence can be connected to someone in a genealogical database, it could lead investigators to a suspect in Guthrie’s apparent kidnapping in Arizona. A law enforcement database didn't turn up any matches to DNA found in gloves a few miles from Guthrie's home.
