Jeronimo Garcia Ceballos of the Mexican Consulate in Tucson, Arizona studies the skull of John Doe 055 at the Pima County Medical Examiner's Office on May 11, 2007. Ceballos was involved with the effort to determine the identity of the remains believed to be of Jesus Alberto Cabral Lopez. Lopez died in May of 2006 while attempting to cross the border into the United States. His bones baked in the desert sun for roughly one year until he was found by Border Patrol. It then took some three months to identify and return him home.
