India, Feb. 27 -- Nancy Guthrie remains missing but new evidence may have come to light, sparking renewed interest. The 84-year-old was reported missing by her family on February 1 and authorities believe she was taken from her home near Tucson, Arizona the night before.

However, in the time since then the FBI and Pima County Sheriff's Department have not been able to find the octogenarian or come up with any suspect they've disclosed to the media. Thus far, one of the biggest leads has been doorbell footage from Guthrie's home that showed a masked man at the door. The FBI released the suspect details based on that. Now, a neighbor's doorbell camera footage might be offering more clues in the kidnapping case.
