TUCSON, Ariz. — (VINnews) – The people who claim to have kidnapped Savannah Guthrie’s mother, Nancy, are demanding $6 million in Bitcoin, according to a local TV station.

“Multiple ransom notes have been sent out to the media, including one that was sent to us,” JJ McKinney of Tucson ABC affiliate KGUN9 reported. “In the letter, the potential kidnappers demanded that the Guthries pay them $6 million before this Monday.”

The notes warned that Nancy Guthrie’s life is in danger if the deadline, set for 5 p.m. local time Monday, is not met, KGUN9 reported.

Savannah Guthrie and her siblings, Annie and Camron, issued a video message Saturday night pleading with the alleged kidnappers to return their mother. “We beg you now to return our mother to us, so that we can celebrate with her,” Savannah Guthrie said, adding that her mother’s return is “very valuable to us” and “we will pay.”

Nancy Guthrie was last seen Jan. 31 after having dinner and a game night at her daughter Annie’s home and was reported missing around noon Feb. 1.

Authorities have conducted multiple sweeps of homes connected to the family in Tucson but have not identified any suspects or persons of interest. The Pima County Sheriff’s Office said the investigation remains active.
