Jiang Yuan had already read through the autopsy report and various scene photos. He summarized in words: "Both victims were seated in the back seat with their hands tied behind them. Due to the concentration of the fire on the upper layer, their heads were severely burned, and the skin on the upper body was practically burned off. However, in the first autopsy, it was still easy to see that the fatal wound on the upper body of both victims was the heart—one stab per person, very precise."
Jiang Yuan: "I reviewed the photos of the rib bones after de-boning of the two deceased. Both had no knife marks on their ribs. This indicates that the killer inserted the knife very precisely between the gaps of the ribs. This is not just precision, it may also relate to the technique and experience."
The few people present nodded as they listened.
