Authorities searching for Savannah Guthrie's missing mother, Nancy Guthrie, are opening up about a key detail in their investigation.
Tucson, Arizona, police previously requested security footage from before Nancy Guthrie's Jan. 31 disappearance, including possible video from Jan. 11, Guthrie's neighbors told NBC News earlier this month.
In a statement released Sunday, March 22, Savannah Guthrie and her family also mentioned the Jan. 11 date when asking Tucson residents for their help in collecting evidence in the case. "No detail is too small. It may be the key," the statement read.
During a segment on the "Today" show Monday, NBC News correspondent Liz Kreutz shared that Pima County Sheriff Chris Nanos explained the significance of the January date and why authorities made the footage request to Nancy Guthrie's neighbors.
The sheriff said Google initially told investigators that a surveillance image of the suspect in Nancy Guthrie's disappearance, a masked man who was seen in Guthrie's front entrance, was from Jan. 11. The date is 20 days before Guthrie was allegedly abducted from her home.
