MEXICO CITY, May 12 (Reuters) - One of the U.S. officials who was killed in a car crash in northern Mexico last month, whom sources say were CIA officers, had been seen days earlier carrying a gun in local security office, said Wendy Chavez, head of a specialized unit of the Chihuahua attorney general’s office tasked with investigating the incident.
U.S. officials are generally not permitted to carry firearms in Mexico.
