On the morning of September 2nd, a Border Patrol agent reported that he had found a body about five miles east of the Lukeville Port of Entry and about three-and-a-half miles north of the international boundary – a location within the park. The victim was a man in his mid-20s. The Pima County Sheriff’s Department was notified and conducted the on-scene unattended death investigation. The man’s identity and nationality are unknown, but he appears to have been a Mexican national. Evidence at the scene, corroborated by the coroner, points to exposure and dehydration as the causes of his death. The area in which the body was located is a route heavily used by illegal aliens and drug smugglers entering the United States.
