Authorities believe forensic evidence may unlock the mystery behind the high-profile disappearance.
Forensic evidence may hold the key to solving the disappearance of Nancy Guthrie, according to local law enforcement.
The Pima County Sheriff’s Department indicated that DNA analysis could play a critical role in identifying the suspect connected to the case. Investigators are working alongside the Federal Bureau of Investigation to process and analyze evidence collected from the scene.
Guthrie, 84, vanished after returning home from dinner with family on January 31. Since then, authorities have released surveillance footage, increased the reward to $100,000, and followed up on thousands of public tips.
The sheriff emphasized that while progress may not always be visible to the public, forensic testing is ongoing and could prove decisive in linking a suspect to the crime.
Officials have not disclosed specific details about the nature of the DNA evidence or whether it has already been matched to a person of interest.
For Guthrie’s family and the community closely following the case, the mention of DNA marks a potentially pivotal moment — though authorities caution that laboratory analysis and legal processes can take time.
Investigators continue urging anyone with credible information to come forward as they pursue all leads.
