Sergio Roniel Zambrano Moreira was 25 when he was last seen on November 11, 2011, while attempting to cross from Mexico into Arizona. He is described as Hispanic, between 5 feet 4 inches and 5 feet 6 inches tall, about 150 to 160 pounds, with black hair and black eyes. The exact location where he was last seen in Arizona is unclear. The Pima County Medical Examiner’s Office is listed as the investigating agency and the case was reported on February 19, 2012; the NamUs entry is MP16866.

The circumstances reflect the known risks of border crossings, and the family’s uncertainty remains unresolved. If anyone had contact with Sergio around November 2011 or saw someone matching his description crossing into Arizona, please share what was observed.
