The mysterious death last year of a U.S. Border Patrol agent – which has turned into a political football reaching the White House – did not appear to result from an attack or fight, the FBI announced Wednesday. Agent Rogelio Martinez died in November 2017 outside Van Horn, Texas, about 110 miles southeast of El Paso. According to an autopsy report from the El Paso County Office of the Medical Examiner, the cause of Martinez’s death is blunt force injuries of the head, but the manner of death is still undetermined.
