Jiang An replied, "Of course, it can be distinguished."
"If this bloodstain was formed when the male victim instinctively touched his face while being attacked, in such a tense situation, his actions would be very fast due to high excitement."
"Thus, in this situation, the speed at which the bloodstain contact point is formed and leaves is very rapid."
Then Jiang An pointed to the male victim's face and said in a deep voice, "The blood wiping traces on this victim's face don't have the characteristics of being wiped quickly."
"On the contrary, based on my understanding of bloodstain pattern analysis, I think it matches the scenario where someone else's bloodstained hand gently touched the face with even a short pause."
"This fully indicates that the bloodstain on the male victim's face was formed by someone else, not himself."
As soon as Jiang An finished speaking, Zhang Yean touched her cheek and then quickly brushed it again.
