Ronal Estuardo Sanchez Gramajo was 28 when he vanished near Nogales, Arizona, in the summer of 2013. On June 21 or 22 he phoned his wife from a group crossing the border and said he was exhausted and planned to surrender to authorities. The guides reportedly gave him a cell phone and told him to call 911 after waiting about four hours so the rest of the group could get away.

A few days later, on June 24 or 25, the group was detained and one of the guides told Ronal’s wife he had heard Border Patrol agents say they had apprehended another member of the group, believed to be Ronal. That tip was never officially confirmed and Ronal’s wife never heard from him again. There is no record of his being in custody and the Pima County Medical Examiner’s Office is handling the investigation.

He was last seen wearing blue jeans, an orange short-sleeved polo shirt and a white Adidas jacket, carrying a backpack with orange, blue and gray stripes, a brown rosary and his identification. Does anyone have information about Ronal’s 2013 crossing or recall seeing someone matching his description after June 22, 2013?
