Debra Schwartz, a Jewish Arizona State University professor, was reported missing on Friday morning when she did not check out of her campground like she was scheduled to.

A three-member technical rescue team that was looking for Schwartz located her on Sunday morning in a canyon below the rim of Oak Creek Canyon, but Schwartz, 59, was found dead.

Two rope rappels were necessary to get in the canyon and find Schwartz and a third rappel was required to reach her body.

A team on horseback, three teams in off-road vehicles, six teams on the ground, a dog team, Yavapai County Sheriff’s Office Air Rescue Helicopter and crew, The Yavapai County Jeep Posse, and three technical rescue teams with three technicians in each team were all sent out to search for her.

The Coconino County Sheriff’s office received the help from the Yavapai County Search and Rescue unit and the state’s air rescue operation on Saturday and forty searchers on the ground were used then, as well as eight search dogs.

Schwartz was a resident of Tempe, Arizona resident and taught English at the university. She was staying by herself at the Pine Flat Campground at Oak Creek Canyon in northern Arizona when she went missing.

Her vehicle, tent, and other camping equipment were found at the Pine Flats campground.

Coconino County Sheriff’s deputies believe Schwartz left her campground for an unknown destination and failed to return.

The department, alongside the Arizona Department of Public Safety air rescue team, conducted a ground search for Schwartz.
