Forensic Expert: 'Scrutinize' Nancy Guthrie's Home for Trace Evidence

Forensic science expert Peter Valentin stressed the critical need for a meticulous examination of Nancy Guthrie's Tucson home, suggesting that even trace evidence could prove vital in the ongoing investigation. Guthrie, who has been missing for over three weeks, was forcibly abducted from her residence on the morning of February 1. Authorities confirmed that DNA recovered from a glove found approximately two miles from her home did not match any samples from inside the residence or known criminal databases. Valentin, speaking on a podcast, advocated for bringing in top specialists in each forensic discipline to scrutinize the property for overlooked clues. He posited that any individual involved in Guthrie's abduction would have left behind evidence of their presence, urging investigators to locate it. The Pima County Sheriff's Department has indicated that resolving DNA technology issues in the case could take months. Meanwhile, a recent lead emerged from a Ring camera capturing twelve vehicles passing by the Catalina Foothills neighborhood, near Guthrie's home, in the early hours of February 1, around the time her pacemaker last synced with her phone. Savannah Guthrie, Nancy's daughter, has publicly appealed for tips, noting that submissions can be made anonymously and may even be compensated.
