A Dutch music promoter and his German girlfriend -- found dead in Joshua Tree National Park -- died after being exposed for hours to desert heat.
Augustinus Van Hove (44) and Helena Nuellett (38) entered the park in a sedan shortly before noon on Monday and took a remote, dirt road to head to Arizona, police said.
Nearly seven hours later, a couple visiting the park found Van Hove's body on the edge of Black Eagle Mine Road.
Sheriff's deputies later found Nuellett's body about a mile from Van Hove, who was the director of 013, a popular concert hall in the Netherlands.
The black Dodge Charger they were renting was found stranded about five miles away. Temperatures during the day topped 41C degrees.
The road had signs warning drivers that it should only be for four-wheel drive vehicles because they may run into soft sand, a park spokesman said. He said it was possible the couple were trying to walk for help.
