What a terrible story...how sad
When I was 7 my 9 year old cousin was electrocuted and killed in our neighbours pond. It had been drained and we (my sister, 3 cousins and the neighbours two kids) had been playing hide and seek. The pond had a pump as well as lights around the edges.
We had no idea until much later that he had been electrocuted. My older sister was "it" and found him just laying in the pond. Being a protective older sister she wouldn't let me see anything but I guess he just looked like he was sleeping so it was kind of a mystery until a few days later when they figured out what happened.
That's when I learned that electricty and water don't mix.
