The FBI has released new videos in the search for Savannah Guthrie's mother, Nancy Guthrie, from the 84-year-old’s front door camera. Images recovered from the camera at Nancy’s home show an “armed individual appearing to have tampered with the camera...the morning of her disappearance,” the Pima County Sheriff’s Department said. It comes after Savannah begged for the public’s help in finding her mother as an alleged ransom deadline passed. The FBI has said it’s investigating reports of a ransom note sent to media outlets, which listed two deadlines that have since passed: Thursday, February 5, and Monday, February 9. Local CNN affiliate KGUN reports it received a ransom note demanding $6 million by Monday.

The deadline on a purported ransom note neared Monday in the disappearance of Nancy Guthrie, the mother of 'Today' show host Savannah Guthrie.

Guthrie said her family is “at an hour of desperation” as the search for Nancy Guthrie continues.

Nancy Guthrie, 84, was last seen on January 31
