Nancy Guthrie Case Explodes as 'Human Bones' Found Near Missing 84-Year-Old's Arizona Home

Police rushed to a desert region 15 miles from Nancy Guthrie's Tucson, Ariz., home after a streamer reported uncovering human remains.

The human bones discovered at the site by A.J. Double U News do not belong to the missing 84-year-old, a news outlet confirmed on Thursday, May 7.

"The bones found near Craycroft and River were determined to be human," the Tucson Police Department shared in a statement. "This will be a prehistoric anthropological investigation. The University of Arizona's Anthropology Department and the Pima County Office of the Medical Examiner assisted. This is not a criminal investigation."

Authorities called the remains "prehistoric," with them being discovered near a site where Native American artifacts have been found.

The investigation into Savannah Guthrie's missing mother, 84, has entered its fourth month, as the elderly woman has not been seen since January 31.

The NBC anchor's mother is said to have spent the evening with her daughter Annie Guthrie and son-in-law Tommaso Cioni before being reported missing the following day, after she failed to appear for her regular Sunday church livestream with friends.

According to footage captured from her doorbell camera, a masked intruder was spotted on her front porch around 1:45 a.m. on February 1.

Nancy is believed to have been abducted before 2:30 a.m., when her pacemaker lost connection to her cellphone, which was discovered left behind.

The investigation remains ongoing as no suspects have been identified in the case.

The Pima County Sheriff's Department has faced backlash for its handling of the case, with Kash Patel blasting the organization for shutting out the FBI during the first four days of the search.

"They did. The first 48 hours of anyone's disappearance are the most critical," the FBI Director, 46, said during an appearance on "Hang Out With Sean Hannity" podcast on Tuesday, May 5. "What we the FBI do, is say, 'Hey, we're here to help, what do you need?'"

Though the White House official agreed it was up to the state's jurisdiction, he believed more information would've been uncovered had their collaboration started earlier.

"When we were finally let in, look at what we did. We went in and got the Ring doorbell," Kash said, referencing footage captured on Nancy's front door camera, which was originally believed to be unavailable.

"We said, 'Hey, is anyone talking to leadership at Google?' We know that there was not a subscription service to capture all of the data ... but can we go into the cache, can we go into the data before it's deleted and see what we can find?" he continued. "That's why you have that image, because the FBI worked with Google to put that image out."
