Dozens of people have been treated for heat-related ailments across the western United States, as the region sweltered on Saturday in dangerous triple-digit temperatures.
At least one heat-related death was reported by authorities in Las Vegas, where a man in his 80s was found dead inside a house that had no air-conditioning.
The victim suffered from other medical issues, but paramedics suspect heat was a contributing factor in his death, said Las Vegas Fire and Rescue spokesman Tim Szymanski.
