Carlos Valenzuela was 42 when he was last seen on August 25, 2008, in the border region between Sonoyta, Sonora, and Lukeville, Arizona. He was reported as Hispanic, about 5 feet 7 inches to 5 feet 9 inches tall, 170 to 180 pounds, with black hair, brown eyes and a tattoo on his left upper arm reading Meche. He was in the process of crossing the border; what happened after he was seen remains unclear.

The Pima County Medical Examiner’s Office opened an investigation and holds the primary case file, but public details are sparse. His family continues to lack answers about his fate.

Did anyone in the Sonoyta–Lukeville area in August 2008 see Carlos or recall anything that could help explain his disappearance?
