Hundreds of Chinese surgeons and medical personnel have been accused of killing death row prisoners by removing their hearts for transplant even before the inmates had been officially declared dead, in a new academic paper.
To do any organ transplant the person has to be alive, not dead, for the organs to be viable.
I dont believe the part that they would use lethal injection.
I think that they would define death as unable to self-sustain life without machine support and lacking in brain activity.
