Anyone with any knowledge of his disappearance is encouraged to reach out to the family through their 24/7 tip line at 844-602-0660, or to the Buckeye Police Department at 623-349-6411. When twenty-four-year-old geologist Daniel Robinson left work on the morning of June 23, 2021, no one knew where he was going or why he was leaving work so early; they only noticed that he was driving west, further into the desert. The unexpected departure was out of character for Robinson, so when he failed to return that afternoon and no one had heard from him outside of work, his disappearance was reported to the police. Days soon turned to weeks and there was still no sign of Daniel. Then, in late July, a month after he went missing, Daniel’s Jeep was found rolled over and crashed in a ravine some distance from the job site. The airbags in the car had both deployed and there was significant damage to the vehicle, but there was no sign of Daniel Robinson, turning a relatively routine missing person case into a bizarre mystery that remains unsolved to this day.
