Authorities are heightening the search for Nancy Guthrie, a mother who went missing from her Tucson, Arizona home on January 31, with the reward for information increasing to $100,000.

Guthrie was last seen at a family gathering before she disappeared. Law enforcement is actively searching the surrounding desert and canvassing nearby neighborhoods in hopes of gathering crucial information.

The Pima County Sheriff's Department has called for residents within a two-mile radius of her home to share any relevant video footage or suspicious activity recorded in the month before her disappearance.

A suspicious individual, described as a male approximately 5'9" tall, was caught on camera near her home on the night she vanished. He was reportedly seen wearing a black Ozark Trail Hiker Pack. Digital forensics experts are working to retrieve any potentially lost footage from the disconnected doorbell camera.

Guthrie's disappearance has gained significant media attention, with her family making emotional public pleas for her return, including heartfelt videos shared on social platforms, requesting the kidnappers to safely return their mother.

As the investigation unfolds, the community remains hopeful for her return, emphasizing that any piece of information could be key to solving this devastating case.
