Border Patrol agents discovered a womanâs body in Montezuma Canyon a mile west of the park visitor center on the afternoon of June 30th. She was identified as Marta Yolanda Gonzalez-Pineda, 34, of Jalapa, Guatemala. Gonzalez-Pineda had been traveling north with a group of illegal immigrants when she apparently died of severe dehydration. Temperatures in the park during the day were close to 100 degrees.
