Washington, United States:
A French couple died while hiking in the New Mexico desert but authorities rescued their nine-year-old son before he too succumbed to the heat, authorities said Friday.
David Steiner, 42, and Ornella Steiner, 51, both from the town of Bourgogne near Reims, had been hiking in the White Sands National Monument on Tuesday afternoon when they apparently died from heat exhaustion, Otero County Sheriff's Detective David Hunter said.
"They underestimated the elements," Hunter told AFP, adding that autopsy results were still pending.
Park rangers found the mother first while on a routine patrol. They checked her camera and saw that she had been with two other people, Hunter said.
Authorities followed her tracks and found the body of the father, with the son nearby. He was dehydrated but responsive and was taken to a local hospital for treatment.
Otero County Sheriff Benny House told local media that the family had been traveling across the United States, visiting national parks and monuments.
According to the Alamogordo Daily News, House said temperatures had been between 100 and 101 degrees Fahrenheit (38 degrees Celsius).
National Parks spokesman Patrick O'Driscoll told the newspaper there was no shade or water along any of the trails in the dune-filled White Sands National Monument.
