A DNA expert has called for a re-examination of the bite flashlight used by a masked man in the search for missing woman Nancy Guthrie. CeCe Moore believes investigators should return to Guthrie's home to search for more DNA evidence, particularly on the bite flashlight.
Moore stressed that DNA on the bite flashlight needs to be examined with extra care, as it could be a 'hardy' source of the perpetrator's DNA, even weeks after the incident.
Pima County Sheriff Chris Nanos said that the case is 'not even close' to a cold case, adding that they have some DNA that they think is still workable.
Nanos also revealed that the Sheriff's Department is still working with the FBI, labs around the country and forensics examiners on 'thousands of video footage' that they still need to sort through.
