Interesting.
Down here we had two guys who had their heads burst into flames, but didn’t die with the first jolt.
Thats why we have lethal injection and Old Sparky was retired.
Not too long ago here, they gassed a guy and he kept breathing normally. That was pretty gross as well. The problem with the electric chair is that it *must* have the proper voltage and current.
The only case I’ve heard of where a properly run chair didn’t work was Albert Fish, the cannibal, who for years had been inserting needles under his skin and leaving them there. He actually shorted the chair out.
