Guthrie disappearance enters tougher phase as leads run dry at 45 days

Nancy Guthrie has been missing for 45 days, and investigators say the lack of meaningful new leads has made the case harder to sustain; while surveillance video from her Tucson home shows non-suspicious activity and hasn’t captured the suspect, the FBI’s doorbell image remains the only clear shot of the suspect. Investigators continue DNA analysis via forensic genetic genealogy, a slow process, as they chase thousands of tips and a $1 million reward without a clear breakthrough.
