Kawai, dressed in a black uniform, presented the first key piece of evidence as the prosecutor in court:
——"Bronchial ash sedimentation"
The deceased was burned alive, with the corneal heat coagulation forming "eagle claw" wrinkles, showing a crawling escape posture. This meant that the person responsible for inspecting the bonfire pile lied, having major murder suspicion.
Fushimi Roku protested in court, stating that being burned alive did not equate to premeditated murder; Kawai immediately presented the second key piece of evidence, which was the "integrity of the woodpile."
Lighting a bonfire is a technical task; it requires reinforcing the wood and maintaining internal breathability, so the woodpile had been reinforced and sealed with ropes before lighting.
This implies that only the residents responsible for building the woodpile had the condition to insert the deceased inside the bonfire pile.
