New reported ransom note in Nancy Guthrie case offers to publicly name kidnapper

A new ransom note sent early Wednesday has offered to name the suspect in the kidnapping of Nancy Guthrie in exchange for Bitcoin, according to a TMZ report.

TMZ and two other Tucson-area television news stations had received the note early Wednesday with an offer to give up information about the suspect in exchange for 1 bitcoin, which is worth about $66,000. The account in the letter appeared to be active.

"TMZ received the note just before 5 AM PT, and the sender claims they've tried unsuccessfully to reach Savannah Guthrie's brother, Camron, and her sister, Annie, by email and text," TMZ reported. "The note goes on, 'If they want the name of the individual involved then I want 1 Bitcoin to the following wallet. Time is more than relevant.'"

There was no confirmation that the ransom notes were authenticated, CNN reported.

It's been 11 days since Nancy Guthrie, 84-year-old mother of "Today" host Savannah Guthrie, went missing from her Arizona home. There was still no suspect or person of interest as of Wednesday.

In a major breakthrough Tuesday, investigators released four images and video captured by a home security camera showing a person wearing a face mask, jacket with reflective material, backpack and black Nitro gloves who appeared at the door of Nancy Guthrie's home in Arizona. The suspect, who appears to be a man, has a light source or small flashlight in his mouth and stands on the front porch of Guthrie's home.

Police Tuesday night had detained a person of interest for questioning in connection with Guthrie's abduction but later released that person.
