Tiagong the Siaolang didn't intend to commit suicide. He jumped down from 6th storey of Eslite building to a rubbish collection area behind the building which normally would have empty card boxes stacked up to 1.8 meters.
It suay suay the card boxes were removed that evening, and he landed on concrete ground.
Based on the above evidence, Taipei police confirmed what we have been suspecting---that he had been vaccinated a few times.
