FBI and sheriff’s deputies searched a Rio Rico home in connection with the Jan. 31 disappearance of 84-year-old Nancy Guthrie, who needs daily medication and is in frail health.

Authorities searched a Rio Rico home linked to the disappearance of 84-year-old Nancy Guthrie, last seen January 31, after a tip suggested she was there. Josefina Maddox, whose son-in-law Carlos is under investigation, said she doesn’t know Guthrie and had no knowledge of the case. The FBI and Pima County Sheriff’s Department are pursuing leads, offering a $50,000 reward, while 88-CRIME provides up to $2,500. Guthrie, described as 5 feet 5 inches, 150 pounds, with brown hair and blue eyes, is in frail health and needs daily medication. Officials urge the public to contact PCSD, FBI, or 88-CRIME with tips.
