Summary based on the NamUs case record (MP82064) and 19 other sources
On June 23, 2021, a 24-year-old field geologist named Daniel Robinson drove away from a remote job site in the desert landscape of Buckeye, Arizona, and was never seen again. A coworker, who was the last person known to have seen him, reported that Robinson left the site, located near Sun Valley Parkway and Cactus Road, around 9:15 a.m. in his blue-grey 2017 Jeep Renegade. He did not say where he was going. Robinson, who had moved to the Phoenix area for his career after graduating from the College of Charleston, was described as a 5'8' African-American man, weighing 165 pounds, with black hair and brown eyes. He was born with a partial right forearm and is missing his right hand. When he failed to return home, his family's concern grew, and he was reported missing that evening.

The search for Daniel took a significant turn nearly a month later, on July 19, 2021, when a local rancher discovered Robinson's Jeep in a ravine approximately four miles southwest of the job site. The vehicle was found on its side, having apparently rolled, and its airbags were deployed. Evidence suggested he had been wearing a seatbelt at the time of the crash. Inside the wrecked vehicle and scattered nearby were many of his personal belongings, including his cell phone, wallet, keys, and the clothes he was last seen wearing. Despite this discovery, there was no sign of Daniel himself. The Buckeye Police Department, along with other agencies, launched extensive searches of the unforgiving desert terrain, covering over 70 square miles with helicopters, drones, cadaver dogs, and ground crews, but found no trace of the missing geologist.

In the years following his disappearance, Daniel Robinson's case remains an unsolved and painful mystery for his loved ones. His father, David Robinson, relocated from South Carolina to Arizona to lead a relentless search for his son. He has organized dozens of volunteer searches and hired a private investigator who raised questions about the official investigation, suggesting data from the Jeep's black box could indicate foul play and that the crash scene may have been staged. While police have stated they do not suspect foul play, the family believes otherwise. The case has highlighted the struggles families face when a loved one disappears and has drawn national attention, sparking conversations about disparities in how missing person cases are handled. The overview of the case is one of profound uncertainty; a young scientist vanished from his work environment, leaving behind his vehicle and personal effects in a manner that offers few clear answers, compelling his family to continue their desperate search for him in the vast Arizona desert.
