Nancy Guthrie Kidnapping: Arizona News Station Receives New Message

4:20 PM PT -- Mary Coleman, anchor for Arizona-based KOLD 13 News, told CNN Friday ... it seems the new note was written by the person who sent the initial, which TMZ received. She said the new note is shorter than the alleged ransom note -- and there was no mention of a deadline.

As you know, the initial note had two deadlines, one which passed yesterday -- and the second is Monday. The new note appears to be a response to the videos made by the Guthries saying they needed proof of life ... and wanted to communicate directly with their mother's captor(s).

A new communication regarding Nancy Guthrie's abduction was sent to a media outlet in the Tucson area ... though the outlet hasn't said yet what it entails.

KOLD-TV reported they received a new message "regarding the Nancy Guthrie disappearance."

The outlet does not say if it is another ransom letter or what kind of communication it is ... but, they immediately alerted the Pima County Sheriff's Department.

PCSD released a statement which reads, "The FBI and Pima County Sheriff’s Department are aware of a new message regarding Nancy Guthrie. Investigators are actively inspecting the information provided in the message for its authenticity."

KOLD anchor Mary Coleman gave a few details on X Friday regarding the note they received ... saying they got it Friday morning, the IP address is different from the one that sent the initial note, and it appeared to them the sender used "the same type of secure server to hide their IP address."

She continued, "The new note contains something the senders seem to think will prove to investigators they’re the same people who sent the first note."

Like us, KOLD was one of the news outlets that received the original alleged ransom note earlier this week.

The first deadline for the ransom note passed at 5 PM local time yesterday ... and the second, more serious deadline, is set for Monday, February 9.

Nancy was last seen Saturday night when her family dropped her off at her home in Tucson. She was reported missing the next day.
