Jiang An's voice slowed down, as if giving a lecture to students, "If the impact occurred before death and caused the fracture, the jagged bone would pierce these blood vessels like a knife, and the blood would seep into the fracture lines."
"The hemoglobin in the blood gradually oxidizes, and over time, it forms the dark brown we see now."
"This is similar to dropping a drop of red ink on white paper, even after ten or eight years, the stain wouldn't completely disappear, just become deeper in color."
This metaphor was easy to understand, and even Chen Biao, who had no knowledge of forensic science, suddenly realized and nodded involuntarily.
"Makes sense!"
"It really makes sense!"
He stood behind Jiang An, looking at the dark brown trace, suddenly feeling that the profound knowledge of forensic science was explained thoroughly and clearly by Jiang An in just a few words.
Chen Biao couldn't help raising his hand to pat Jiang An on the shoulder, "Mr. Jiang, I admire you!"
