Nearly 100 days after Nancy Guthrie disappeared from her home in Arizona, investigators say the case may finally be moving closer toward a breakthrough.
The 84-year-old mother of Today show host Savannah Guthrie vanished from her residence in Tucson's Catalina Foothills on February 1.
Authorities believe she was abducted from the property around 2:30 AM local time, prompting a massive joint investigation involving the FBI and the Pima County Sheriff's Department.
Forensic experts say genetic genealogy may ultimately help identify a suspect, as investigators have been closely examining a hair sample found at the scene.
Thousands of tips flood investigators since the investigation began, and authorities are now narrowing their focus toward information connected to the masked individual seen in the surveillance footage.
