Jiang An listened quietly and nodded slightly.
"I think you should understand what I'm trying to convey."
"Regarding the neck marks, there are many possibilities."
"However, in the process of forensic studies, the depth of skin marks directly reflects the magnitude of force."
"During the interaction of forces with the human body, different angles and strengths can produce completely different results."
Jiang An continued, "It's like using a rope to pull something."
"For different pulling positions and angles, the results naturally vary."
"The neck is a structure similar to a cylinder."
"When two ropes act on the neck simultaneously, there must be a crucial pressure point."
"And this pressure point directly leads to: very obvious marks, while the pressure marks at the other point are relatively lighter."
As he spoke, he intentionally pointed to the ligature marks at the top of the photo with his finger.
