Daniel Robinson, 24, was last seen June 23, 2021, when he left a remote field geology job site near Sun Valley Parkway and Cactus Road in Buckeye, Arizona, in his blue-grey 2017 Jeep Renegade. A coworker reported he departed the site around 9:15 a.m. and he did not say where he was going. Robinson was described as a 5 feet 8 inches African-American man, 165 pounds, with black hair and brown eyes; he was born with a partial right forearm and missing his right hand.
When he did not return home that evening, family reported him missing. On July 19, 2021, a local rancher found his Jeep on its side in a ravine about four miles southwest of the job site; the vehicle had apparently rolled, the airbags had deployed, and items including his phone, wallet, keys and the clothes he had been wearing were inside or scattered nearby. Searches covering more than 70 square miles with helicopters, drones, cadaver dogs and ground crews turned up no sign of Daniel. His father, David Robinson, moved to Arizona, organized volunteer searches and hired a private investigator who questioned the crash scene and black box data; police have said they do not suspect foul play while the family disagrees.
What did anyone in the Buckeye area see or hear around June 23 that might help explain how Daniel disappeared?
