The disappearance of Nancy Guthrie has taken yet another bizarre turn.

As investigators continue searching for answers, Pima County Sheriff Chris Nanos is pushing back on an alleged ransom-style email sent to TMZ — saying the so-called demand letter is not believed to be real.

“It is a shame that these types of events occur,” Nanos said, reacting to the latest strange claim surrounding the high-profile missing person case.

The sheriff’s comments come as the investigation into Nancy’s disappearance grows more chilling by the day.

Authorities have already confirmed that Nancy’s home has been declared a crime scene, and investigators say possible DNA evidence was collected from inside the property.

“We took some samples that we hope will have enough of a DNA profile,” Nanos told NBC News in a report shared on Today on Feb. 3, “that will give us some identification as to what we’re looking at.”

Days later, during a Feb. 5 press conference, Nanos laid out a haunting timeline of what investigators believe happened before Nancy vanished.

According to the sheriff, Nancy had returned home after visiting family. About four hours later, something strange happened.

“At 1:47 a.m., the doorbell camera disconnects,” Nanos said.

The system reportedly detected a person near the doorbell camera, but the clip was automatically overwritten because Nancy did not have a subscription to the service. Even so, Nanos said investigators had not given up on trying to recover the lost footage.

Then came another troubling clue.

“At 2:28 a.m., Nancy’s pacemaker app shows there was a disconnect from the phone,” the sheriff said.

Hours later, Nancy’s family went to check on her.

“At 11:56 a.m., the family checks on Nancy and discovers her missing,” Nanos said. “At 12:03 p.m., 911 is called in to the Pima County Sheriff’s Department.”

Within minutes, deputies were at the home.

“Our patrol teams arrive,” he said. “They see the scene and we start our response with our search-and-rescue teams, and our detectives on various units.”

The case took a major turn on Feb. 10, when authorities released surveillance images of a possible subject in the investigation.

The photos, recovered from a camera on Nancy’s property, show a person wearing a ski mask and a backpack approaching the home. The individual appears to strike the camera with their fist.

Authorities had previously said the camera was found broken when police arrived at the house.

In a statement shared with E! News, officials said the FBI and Pima County Sheriff’s Department had been working with private-sector partners to recover footage that may have been lost, damaged, corrupted or otherwise inaccessible.

“The video was recovered from residual data located in backend systems,” the statement said.

Investigators said the newly recovered images show an armed individual who appeared to tamper with the camera at Nancy Guthrie’s front door on the morning she disappeared.

For Nancy’s family, the new images offer a terrifying glimpse into what may have happened in the early morning hours before she vanished.

But as the search continues, officials are also warning the public not to get distracted by fake claims and attention-seeking messages.

The alleged demand letter sent to TMZ is now being dismissed by the sheriff as false — another disturbing sideshow in a case already filled with fear, mystery and unanswered questions.

Authorities have not announced an arrest, and the search for Nancy Guthrie remains ongoing.
