A new twist has erupted in the Nancy Guthrie mystery, and this one comes with an explosive claim.

TMZ says it has received another email from the person who claims to know who kidnapped Guthrie. This time, the sender says he has a phone hidden away that allegedly contains video of the “main guy” with Nancy on what may have been the day she died.

The outlet says it has authenticated that the email came from the same person who sent earlier messages. According to TMZ, the sender referenced an old Bitcoin address that matched previous communications, along with the same alias used before.

In the latest message, the person appeared to mock reports that the FBI believes the writer could be a woman.

“I am not the idiot who recently called in a tip about her burial site in Mexico,” the sender allegedly wrote.

The person also claimed there were two kidnappers involved. TMZ noted that the sender had previously insisted more than one person was behind Guthrie’s disappearance and death.

Then came the jaw-dropping demand.

The sender claimed he has “a phone stashed in a secure location” that protects both the information on it and the device itself. He said the phone allegedly contains what he described as proof that would hand over the suspects “on a silver platter.”

According to TMZ, the person claimed the phone includes a short video of the “main guy” with Nancy on what was “probably her last” day alive. He also claimed it contains photos of both people allegedly involved, as well as names, addresses and ages.

The sender said the phone is hidden in a place that is “easy to access if you know where it is.”

But there is a catch.

He is allegedly demanding one Bitcoin in exchange for the password, and included a new Bitcoin address in the message.

TMZ said it responded by asking the sender to provide one screengrab of Nancy from the alleged video to prove the claim is real.

The outlet also said it has forwarded the latest email to the FBI.

For now, the claim remains unverified, but the new message has added another disturbing layer to a case already packed with dark questions, mystery emails and alleged ransom-style demands.
