TUCSON, ARIZONA (VINnews)- Authorities in Pima County are investigating a ransom note received by a local news station as part of the ongoing search for Nancy Guthrie, the 84-year-old mother of NBC’s “Today” show co-host Savannah Guthrie.

Pima County Sheriff Chris Nanos confirmed to CBS News that the note was sent to an Arizona television station on Monday. The station reportedly agreed not to publicize it initially. According to the sheriff, the note included specific details about Nancy Guthrie’s home and what she was wearing on the night she disappeared, though officials have not verified the accuracy of those details or the note’s legitimacy.

Investigators are taking the communication seriously, with the FBI reviewing the note and sharing it with Savannah Guthrie, Nanos said. The sheriff emphasized that detectives are coordinating closely with federal authorities and pursuing all leads in what they believe is an abduction.

Nancy Guthrie was last seen at her home in the Catalina Foothills area near Tucson on Saturday night, around 9:30 p.m. She was reported missing on Sunday after failing to attend her regular church service, prompting family members to search the property before contacting authorities.

Sheriff Nanos has described the home as a crime scene, citing signs of forced entry and other concerning evidence indicating that the 84-year-old did not leave voluntarily. Blood was reportedly found at the scene, and Nancy Guthrie requires daily medication for her health—authorities have warned that her condition could become critical without it. She is described as sharp-minded with no cognitive issues, and her disappearance is not believed to be related to wandering or dementia.

Multiple media outlets, including TMZ, have reported receiving alleged ransom demands, some reportedly seeking millions in Bitcoin cryptocurrency with a deadline for payment. The Pima County Sheriff’s Department has acknowledged awareness of circulating reports about possible ransom notes and reiterated that they are “taking all tips and leads very seriously.”

Savannah Guthrie has publicly appealed for prayers on social media, describing her mother as “a woman of deep conviction, a good and faithful servant,” and urging supporters to join in praying for her safe return.

A reward of up to $2,500 has been offered by 88-Crime, a nonprofit partnering with local law enforcement, for information leading to an arrest in the case. The FBI and other agencies are assisting in the investigation, which includes searches by drones, helicopters, search-and-rescue dogs, and volunteers.

Anyone with information is urged to contact the Pima County Sheriff’s Department or submit tips anonymously through available channels. Authorities continue to stress the urgency of locating Nancy Guthrie as soon as possible.
