(Qunatico, VA) The investigation into the disappearance of Nancy Guthrie reached 100 days on Tuesday and may hinge on DNA evidence still being analyzed by scientists at the FBI laboratory in Quantico, Virginia. 

Guthrie, the mother of Savannah Guthrie, co-anchor of the “Today” show, was reported missing on Feb. 1. 

DNA recovered from Guthrie’s home in Tucson, Arizona was initially sent by Pima County Sheriff’s Department detectives to a private laboratory in Florida for analysis. Weeks later, the evidence was transferred to the FBI crime laboratory in Quantico, where law enforcement sources told CBS News the analysis remains ongoing. 

Investigators have not publicly disclosed details about the sample or where it was recovered. 

Another lead that has drawn significant attention is footage from a Ring doorbell camera that showed an individual wearing a ski mask, gloves and a backpack at Guthrie’s front door the night she disappeared.
