Three elephants die mysteriously in Hua Hin

Initial autopsy of the three elephants showed internal bleedings in the hearts, lungs, and livers which caused the three elephants to succumb to instant death simultaneously.

This does not make sense

Dying from electric current makes burns on the areas where it entered the body

and it stops the heart from beating (because the heart is triggered by electric potential which is generated in the heart = natural pacemaker

I never heard of internal bleeding caused by electricity only caused by rat poison

The story is very fishy

Just because you lack knowledge in a particular area does not make it "fishy" and does not mean it "does not make sense".

Electric shocks often cause internal bleeding in humans, after a person receives a severe electric shock but shows little external injury they are often given a CT scan to check for internal injury.

It comes down to the resistance of the skin, if the resistance is low then the current will pass through the skin and damage internally, if the resistance is high then it will not and will result in damage only on the surface.

If it was raining and the skin of the elephants was wet then the skin resistance would be much reduced and it is much more likely that they would suffer internal injuries. Common areas to be inured by electrocution are the heart, lungs, kidneys and eyes and they might also suffer dislocation or broken bones due to convulsion.

The tip of the trunk having been cut off would really be the give away. Why would they cut the tip of the trunk off of the elephant that had died from poisoning?
