"Were the footprints left by the murderer?"
"Other than fingerprints, there are only footprints at the scene, but footprint analysis is extremely difficult for us to handle at this point..."
Lu Chuan understood that footprint analysis in most Crime Scene Investigations was mostly about estimating height using formulas based on foot length.
"Who reported the crime?"
"The victim's wife, she found her husband dead when she returned home."
"No need to compare the fingerprints; the killer should be the victim's wife."
"Hmm? The wife?"
What's going on?
Before Wang Gang could ask, Lu Chuan took out the footprint photos from the file.
"The murderer didn't leave in a hurry, but instead carefully designed the direction of the footprints. In reality, the person entered the room walking backward from outside the door."
"How did you see that?"
