Robert Joseph Downs, 48, was last seen the afternoon of May 10, 2024, at his Sun City, Arizona, home on North Agua Fria Drive. A friend reports spending most of that day with him and dropping him off at home about 4:00 PM; Robert was reported missing on May 12. His phone and wallet were left at the residence.

On the morning of May 13 his truck was found abandoned on Castle Hot Springs Road near the Holcim Castle Hot Springs Rock Pit #2, in a remote area of far north Peoria — a significant distance from his Sun City address. Downs is described as a white male, 5 feet 6 inches, 170–180 pounds, with long brown hair below his shoulders, brown eyes, and a trimmed brown and gray beard and mustache. The Maricopa County Sheriff’s Office is investigating and has asked for public help.

There is a gap between the reported 4:00 PM return on May 10 and the truck’s discovery on May 13; his personal effects remaining at home is a key detail. If anyone has information about Robert’s movements after May 10 or saw the truck on Castle Hot Springs Road, please share what is known.
