I have a theory about this autopsy controversy. Our jj0ng could have been on drugs. In fact, I think all idols could be using some kinda drugs - energy boosters steriods and stimulants - Otherwise how would ya explain them performing such high energy dances on stage while on extreme diets to maintain their unrealistic Korean dream figures. Anyways back to jj0ng, he could have been too. He was so painfully thin with sunken cheeks which could have been due to drug use. It was most likely SM decision to not do the autopsy to hide this reality. Doing autopsy would expose not just Jj0ng but also every other idols drugs culture.
Often time I have come across rumours of managers procuring these drugs for idols use. I have also read reports on how celebs do coke and such to maintain their thin body shapes. Sull1 was also rumoured to be a substance user and I believe they did not do her autopsy as well. Also G0 h@ra. Sull1, H@ra and our jj0ng were friend who did things together. Jj0ng was also close with 1ron, another drug user. So... its simple math.
Others from their friends circle - 1u, Taey0ng, Yer1, they all lost weight drastically. 1u shared her crazy diet plan to explain her weight loss but the way she was trying so hard to explain only proves she tryna hide the real secret.
Fun fact: Use of drugs to control weight was revealed by the very bony Kate M0ss herself. Long long time ago, she said she and all her fella models were all high when they walk the runway.
