The anonymous individual who has been communicating with TMZ for months about the disappearance of Nancy Guthrie has refused to turn over an alleged video of one of her purported kidnappers, citing fears that sharing the file could expose his identity through embedded metadata, according to a new report.

TMZ said Friday it received a new letter from someone previously in contact with the outlet, who claimed to have video of one of the alleged suspects and Guthrie on a phone stored in a "secure location." The development marks the latest twist in an extortion-style correspondence that has unfolded sporadically since shortly after the 84-year-old's disappearance from her Tucson-area home on February 1.

According to TMZ, the person who sent the latest letter has the same email address and Bitcoin address as the individual who first contacted the outlet weeks into Guthrie's disappearance. The sender also claimed that two people were responsible for Guthrie's kidnapping, and that the alleged video shows the "main guy" among them.

The letter described the contents of the hidden phone in specific detail. "I have a phone stashed in a secure location guaranteeing both the information it stores and the safety of the phone," the sender wrote, according to TMZ. "What it contains is my definition of delivering them on a silver platter, a short video of the main guy with nancy the day that was probably her last, pictures of both involved, names and addresses and age."
