Tragic Hiking Deaths in Texas Heat for Florida Man and Stepson.

A Florida man and his stepson died while hiking in extreme heat at Texas' Big Bend National Park. The 31-year-old man and his two stepsons were hiking when the younger boy became sick and unconscious. The father left to hike back to the car to get help, while the older brother attempted to carry the 14-year-old back to the trailhead. Officials said temperatures at the time were around 119 degrees. The 14-year-old was found dead, and the father was later found dead inside his vehicle, which had crashed over an embankment. The 21-year-old stepson has since returned home to his family in Orlando.
