My dad saw a thief executed in China during WWII. They knelt him down and an officer shot him in the back of the head.
The family could not recover the body till they paid the fine. The process from arrest to execution was less than 24 hours.
He had been caught in the US barracks with about $5 of money and a couple of GI watches.
I have heard the Soviets did the same thing in the showers of their prisons. No last meal, no family just kneel , bang, clean up the mess.
