Oscar Alfredo Bustos Arroyo, known as El Cholo, was 28 when he left Mexico for Arizona in spring 2013 and last made contact on April 29, 2013, from Sonoita in Pima County, Arizona. He is described as a Hispanic male, about 5 feet 4 inches, 150 pounds, with brown hair, brown eyes and a goatee. His file notes a mole on his right gluteus and a small tattoo; the tattoo’s location is not recorded.

Oscar was reportedly traveling a route between Jiladel and Casa Grande north of a Mexican military camp. Nothing further is known about his movements after that final contact. The case was reported to the San Mateo County Sheriff’s Office on April 21, 2018, and remains open. Clothing, personal items and other details from the time he disappeared are not available.

If anyone saw Oscar in Arizona in late April 2013, or remembers his intended route between Jiladel and Casa Grande, please share what you know.
