PHOENIX – A human skull uncovered during the search for Daniel Robinson in a remote West Valley area is not of the missing Phoenix man, authorities said last week.

The skull was discovered on July 31 in the area south of where a rancher found Robinson’s vehicle wrecked in a ravine about two weeks earlier, the Buckeye Police Department said in a press release Thursday.

“It was later determined the remains do not belong to Daniel,” the release said.

The only other bones found during the search were from animals, police said.

Robinson, 24, hasn’t been heard from since he drove west from a job site into a desert area near Sun Valley Parkway and Cactus Road in Buckeye on June 23.

His Jeep Renegade was found July 19 about 4 miles southwest of the work site. It was on its side with the airbags deployed. Robinson’s cellphone, wallet and keys were found at the scene.

Police said they believed Robinson was wearing a seatbelt when the SUV rolled, and they didn’t suspect foul play.

Robinson is 5 feet, 8 inches tall and weighs 165 pounds and has black hair and brown eyes. He is missing his right hand and part of his forearm.

He regularly works in remote areas as part of his job as a hydrogeologist with an engineering firm.

Buckeye police and other agencies searching for Robinson have scoured more than 70 square miles by ground and air, using cadaver dogs, off-road vehicles, a drone and a helicopter.

Robinson’s father traveled from South Carolina to Phoenix during the search and has set up a GoFundMe account to help cover the costs of a private investigator, printing flyers, search team supplies and hotel expenses.

Anyone with information about the case was asked to call the Buckeye Police Department at 623-349-6400.
