Pima County Sheriff Chris Nanos acknowledged Thursday that the investigation into the disappearance of 84-year-old Nancy Guthrie has proven to be complex and time-consuming, as authorities continue to analyze DNA and digital evidence gathered over the past six months. Nancy Guthrie, who disappeared in February, remains missing as efforts by local police and the FBI persist.

In a statement posted on the social media platform X, Sheriff Nanos emphasized that the case remains active and ongoing. A dedicated task force comprised of deputies from the Pima County Sheriff’s Department and FBI agents continues to explore every viable lead in hopes of locating Guthrie and providing answers to her family.

“The analysis of DNA and digital evidence has been underway for the past six months. This work is complex and time-intensive, but investigators continue to pursue every credible lead,” Nanos stated.

The sheriff also echoed remarks made by Guthrie’s daughter, Savannah Guthrie, a television personality on the “Today” show. Savannah recently issued a public appeal urging anyone with information to come forward.

“As Savannah Guthrie recently said, it is never too late to do the right thing,” Nanos said. “Anyone with information is urged to come forward and help bring this case to a resolution.”

Sheriff Nanos, who has faced criticism over his handling of the investigation, expressed cautious optimism this week, saying he remains “still positive” that the case will be resolved. The joint effort by local law enforcement and federal authorities underscores the ongoing commitment to unraveling the circumstances surrounding Nancy Guthrie’s disappearance.

Despite months of investigation, few concrete leads have emerged, and authorities continue to rely heavily on forensic analysis and public cooperation to advance the case. The search remains a top priority for law enforcement officials in the Pima County area.
