A 14-year-old boy and his stepfather have died in Texas after they went on a hike in extreme heat where temperatures reached 48.3C (119F).
The unnamed teenager lost his life after he fell ill and became unconscious in the scorching conditions, while the 31-year-old man died in a car crash as he tried to get help.
The tragedy happened on the Marufo Vega Trail in Big Bend National Park where the pair were hiking along with the boy’s 21-year-old brother.
In an attempt to get assistance after the 14-year-old became unwell, the stepfather left the scene and went back to his vehicle while the older brother tried to carry his sibling on his back to where the trail began.
Authorities were first told about the emergency at 6pm on Friday.
A team of park rangers and US border patrol agents then reached the scene at 7.30pm and found the boy dead.
Half an hour later, the authorities in Texas discovered the vehicle which had crashed over an embankment at Boquillas Overlook.
The stepfather, from Florida, was declared dead at the scene, while the older brother was unhurt in the tragedy.
