Zhang Yean also looked surprised.
However, she was full of curiosity about Jiang An's subsequent analysis.
Jiang An began, "Suppose the deceased's head was missing before the fire started, then the burning on the upper trachea would be more severe than that in the lungs."
"Because lung tissue is enclosed, and separation at the neck would expose the upper trachea."
As he spoke, Jiang An pointed to the upper trachea of the deceased woman. "Look, the burn on the upper trachea of this deceased woman is very mild."
"In my view, this level of burning is quite similar to the burn level in the lung tissue inside the chest cavity."
"This allows us to draw a very important inference."
"What inference?"
Zhang Yean asked eagerly.
"The exposure time of the woman's upper trachea to the fire is very similar to that of the lung tissue inside the chest cavity."
"Very similar?"
Hearing this term, the four people looked at Jiang An with a mix of understanding and confusion.
