Authorities are investigating another note regarding the disappearance of Nancy Guthrie, as the mother of "Today" anchor Savannah Guthrie has been missing since the night of Jan. 31.

The FBI and the Pima County Sheriff's Department said they received a "new message" regarding Nancy Guthrie and are investigating it, according to a Friday X post.

"Investigators are actively inspecting the information provided in the message for its authenticity," the department wrote.

Arizona-based news station KOLD confirmed on social media that it also received the new note on Friday.

On Feb. 3, KOLD reporter Mary Coleman told CNN that TMZ and KOLD reportedly received a ransom note in the case that allegedly mentioned a deadline, dollar amount and specific details that only Guthrie's abductor might know.
