Death by electrocution?

Question

Why is it that a convict's bladder is always found to be empty (and/or tightly contracted) during autopsies after electrocution in the electric chair but their bladders are always partially full after other various methods of execution..ie lethal injection,gas chamber,hanging,firing squad?

I thought the bladder emptied during death,but not one inmate who was electrocuted in the electric chair had any urine in their bladders,but those who were executed by other methods did.

Answer 1

The heat generated by the electric charge would explain a dry/contracted bladder.~
