A guy in his thirties is found dead in a forest. The shocking thing about the body is that he is wearing his swimming trunks snorkel and a facemask.
For your information, the nearest lake is some 10 miles away and the sea is hundreds of miles away.
How did he die then?
The forest in which he is found dead had caught fire. In order to turn off the fire, a fire fighting plane scooped up water from the nearby lake and dropped on the fire. Unfortunately, while scooping up the water, they had accidentally picked up the guy who was snorkeling in the lake. While dropping the water, they dropped that guy as well and he died.
