Yep, I’ve plenty of stories about instant BBQd squirrel bits. So high voltage can most definitely do interesting things. In my story case, I simply needed a murder, and the killer knew what he was doing, so it was relatively clean, so to speak.
In the case of the electrocution, it was premeditated while also trying to have it be masked as “natural”, so big wounds would be a give-away that it wasn’t natural.
