Ancient Skeleton Discovered Near Nancy Guthrie Search Site: Experts Estimate Age at 1,000 Years

In Tucson, Arizona, the unearthing of ancient human remains near the area where Nancy Guthrie is believed to have been abducted has highlighted the harsh realities of the Sonoran Desert. According to experts, this vast and unforgiving landscape can reveal a dozen or more bodies each year, with ample space to conceal them.

Nancy Guthrie, the 84-year-old mother of “Today” show co-host Savannah Guthrie, became the center of national attention due to her daughter’s fame. However, it was quickly determined that the discovered remains were unrelated to her disappearance.

James T. Watson, an anthropologist from the University of Arizona, spoke with Fox News Digital about the findings. Contrary to initial reports of a solitary bone, Watson clarified that a complete skeleton was actually found at the site.

They belonged to someone believed to have been buried between several hundred and 1,000 years ago, he said.

“Whether it is a thousand years old or 50 years old, these are human remains,” Watson said, adding that he hopes additional discoveries are treated with dignity and respect if searches continue in the Guthrie case.

A local YouTuber named AJ Wysopal came across an exposed bone while conducting an amateur search for Guthrie less than 5 miles from her home in the Catalina Foothills on May 7. Guthrie is believed to have been kidnapped out of her house in the early hours of Feb. 1.

Authorities quickly determined that the remains were human — and also that they were significantly older and unconnected to Guthrie’s suspected abduction. They are called prehistoric because they belong to someone who died before there was written language in the area, Watson said.

There is also a known archaeological site nearby, and Watson said that ceramic artifacts uncovered at the scene are consistent with known examples there.

“All of that contextual evidence allowed me to be pretty sure that this individual was in fact Native American,” he said. “The ceramics really sort of drove home that point.”

The remains have since been transferred to the Tohono O’odham Nation, a Native American tribe with a large reservation just west of Tucson. No additional research or testing is expected, he said.

Watson said that a combination of the Sonoran Desert’s harsh terrain and new developments on land that has been largely untouched for centuries often lead to similar discoveries as the search for Guthrie continues.

“The desert there is a pretty harsh environment and obviously it’s been settled for hundreds, thousands of years,” he told Fox News Digital.

And in addition to inadvertent archaeological discoveries, the region is also near the U.S.-Mexico border, where illegal immigrants have for years been attempting to cross illegally in those same harsh conditions.

On some occasions, he’s been called to the findings of their remains, he said.

“There are literally probably hundreds of bodies that are discovered every year out in the desert,” he told Fox News Digital.

Like the recent find at River and Craycroft Roads, some are exposed by natural causes, including erosion caused by the region’s powerful ephemeral rivers, which are mostly dry but flood violently during heavy rainfall in the desert. Others have been unearthed by real estate development, Watson said.

And there could be many different reasons why they came to rest where they are found.

So there [are] a lot of places that an individual could get lost or pass away — or hide a body,” Watson said. “I think…as people start to poke into some of these crevices that don’t normally get poked into into across the desert, they’re likely to find more individuals.”

The investigation into Guthrie’s disappearance is ongoing, and there is a combined reward of more than $1.2 million in play.
