A key prerequisite for forming these friction marks is that there is no tight binding between the rope and the tree branch, leaving a certain gap.
If the rope were tightly bound and fixed to the tree branch, even if the deceased struggled and moved, the sliding amplitude would be minimal, and such obvious friction and wear marks would not be left.
The clear traces at the scene indicate that there was a significant gap between the rope and the tree branch, which resulted in these striking and irreversible sliding friction marks.
As Xu Ming squatted on the ladder, intently observing the details of the marks on the tree branch, Director Tang looked up, closely watching his every move.
Seeing Xu Ming's grave expression, saying nothing, Director Tang's heartbeat suddenly accelerated, and he felt uneasy at heart.
