The search for Nancy Guthrie, the mother of ‘Today’ show host Savannah Guthrie has entered the 50th day with investigating authorities still looking to piece together clues. The 84-year-old was last seen at her home near Tucson, Arizona, on February 1. Investigators believe she was abducted after surveillance footage showed a masked individual at her door.

A former US detective, Brian Martin, who helped solve a decades-old child murder case, said the investigation remains active and far from going cold. “Nancy’s case is still very fresh,” he said, adding that he remained optimistic the suspect would be identified.

Martin suggested that forensic evidence could prove crucial. “I’m sure they have an item of evidence… that was probably left by the suspect,” he said, pointing to the potential importance of DNA analysis.

Authorities have confirmed that samples were recovered from inside the home and from an item found nearby. However, officials say existing DNA has not matched profiles in the national CODIS database.

What to know about the investigation into Nancy Guthrie's disappearanceThe masked suspect caught on the doorbell camera of Nancy Guthrie’s home.

 

The Pima County Sheriff’s Office said it is exploring the use of investigative genetic genealogy, a technique that can identify suspects through distant relatives in public DNA databases.

Martin noted that such methods have helped resolve long-standing cases, including the murder of eight-year-old April Tinsley, which was solved decades later.

Despite progress, officials caution that forensic testing can take time. Sheriff Chris Nanos has said further DNA analysis could take up to a year. Investigators have also examined surveillance footage showing at least one masked suspect and have followed up on tips and mobile phone data. Several individuals were questioned and later released without charge.

Local frustration has grown as the case remains unresolved. A recall effort has been launched against Sheriff Nanos, reflecting concerns about the handling of the investigation.

Meanwhile, Guthrie’s family has continued to appeal for information. “We continue to believe it is Tucsonans, and the greater southern Arizona community, that hold the key to finding resolution in this case,” they said in a recent statement.
