Marco’s Last Known Location
Marco disappeared while working at Keeylocko Ranch, near Coleman Road and Ajo Highway (State Route 86), approximately 7 miles from Robles Junction and 40–50 miles southwest of Tucson, Pima County, Arizona.
Marco’s home was a bus on land off State Route 286 (Sasabe Highway) on Stallion Road in Three Points. He had no running water, no electricity, and no vehicle. He was a well-known, familiar face in the Three Points community.
Three Points / Robles Junction, Pima County, Arizona — the area where Marco lived and where he was last seen. The Tohono O’odham Nation reservation, Altar Valley, and Route 286 south to the Mexican border compose the surrounding landscape.
The Land Where Marco Disappeared
Three Points (Robles Junction) is an unincorporated community in Pima County, Arizona, at the intersection of State Route 86 (Ajo Highway) and State Route 286 (Sasabe Highway), approximately 30 miles southwest of Tucson. In 1994, it was an extremely remote area.
The surrounding landscape is defined by the vast Tohono O’odham Nation, one of the largest Native American reservations in the United States. The lands extend across southern Arizona and into Sonora, Mexico. The Altar Valley, a broad desert basin flanked by mountain ranges, runs south from Robles Junction toward Sasabe and the international border.
The terrain is harsh. Dense desert scrub, rocky washes, extreme summer heat, and almost absence of permanent water outside of ranches and wells.
Marco had no vehicle. He walked, or hitchhiked, or found rides along these desert roads. In 1994, there were very few African American residents in the Three Points area. Marco stood out and was well known.
If you saw or interacted with a very tall Black man wearing a black eye patch in the Robles Junction, Three Points, Altar Valley, or Ajo Highway corridor in the spring or summer of 1994, that person was almost certainly Marco.
If you have ever found any items, bones, or any human remains in the desert west or southwest of Tucson, particularly in the Altar Valley, near Coleman Road and Ajo Highway, or on the Tohono O’odham reservation , please report it. Those details could hold the key to this case.
Unidentified Remains
Could One of Them Be Marco?
DNA comparison is possible even from decades-old skeletal remains. Forensic genetic genealogy has recently solved Pima County cases that were thought permanently closed through DNA analysis and the Doe Project.
Pima County has one of the largest repositories of unidentified human remains in the United States. The Pima County Office of the Medical Examiner holds records on over a thousand unidentified individuals recovered over the past three decades from desert terrain across the county including areas near Three Points, the Tohono O’odham Nation reservation, and the Altar Valley.
Marco’s physical description is highly distinctive: an unusually tall (6’3″–6’4″) African American male, with evidence of a non-functional right eye, a throat scar, and very large feet (size 12 boots). If you have knowledge of any unidentified remains found in Pima County or on adjacent tribal or border lands that match this profile, please contact the agencies below.
