Heat stroke doesn't hit people like a lightning strike. It's a cumulative thing. If you and I were both walking in the extreme heat and got heat stroke, it is highly unlikely we would both collapse at the same time. One of us would start feeling symptoms before the other, due to physical differences, tolerance, etc.
Heat stroke would be a very plausible explanation if the dude were hiking alone and found dead. However, when hiking with another adult, it's likely that if one person was suffering from heat stroke, the other would be well enough to tough it out for another 1.5 miles to the car, and get help. This didn't happen. They were all found close together, and there was plenty of water in the guy's CamelBak pouch.
However, let's say they were all exposed to toxic algae at the same time -- say by swimming in the river. That's something which could have hit them all nearly simultaneously, incapacitated them, and then an eventual death came from heat stroke.
I simply don't believe that two adults got heat stroke to such an extreme degree at the exact same time, where neither went for help, and neither drank all the water they had on them. This looks like a sudden event.
