FBI Analyzes Nancy Guthrie Home DNA 100 Days After Disappearance

100 days into Nancy Guthrie’s disappearance, FBI scientists in Quantico are still analyzing DNA recovered from her Tucson home in hopes of identifying her abductor.
The sample was first sent to a private Florida lab, then transferred to the FBI; investigators have not disclosed whether it came from hair, bodily fluid or another source because the case remains active.
A separate DNA lead already collapsed after socks found about 2 miles from the home were traced to a restaurant worker unrelated to the case, underscoring why the current testing is taking time.
Ring doorbell video showing a masked man at Guthrie’s front door the night she vanished remains a central clue, while investigators continue sorting through thousands of tips and digital records.
The FBI is still seeking public help, with rewards totaling more than $1.15 million for information leading to Guthrie’s recovery or the arrest and conviction of anyone involved.
