Sean: "Okay, let me give you some advice!"

After saying this, Officer Hunter unconsciously stretched his head over. He was naturally very curious about Senior Sean's inference just now. After all, he had investigated the scene several times, but he really didn't find anything. He just intuitively told

He's not right.

Teacher Sean said: "Karl, you underestimate the seat of this car seat. Do you see anything?"

Xie Yu only saw stains of blood, but he really didn't see anything!

Sean knew that Xie Yu didn't see it, so he didn't pretend to do it. Instead, he directly drew an arc on the photo with a pen and said, "Karl, do you think this looks like a person's buttocks?"

According to the arc drawn by Senior Sean, Xie Yu thought about it and said: "Teacher Sean, it looks like an arc. Oh, I understand you said that the suspect is wearing a raincoat or something that can block

Blood-stained cover!"

"But if that's the case, shouldn't there be more obvious breaks in the blood stain?"

Sean sighed and said, "This is what the police academy teacher taught you. You are only seeing the surface."

"Let me ask you again, what material is this seat made of?"

Without waiting for Xie Yu to answer, Sean said directly: "The seat material of this low-end car is ordinary linen, unless it is my personal preference!"

"Linen is breathable and soft, but it is also very absorbent. When the suspect left the car seat, the blood stains on his buttocks would naturally spread."

"However, you haven't been in the police for a long time, so it's your fault if you can't tell!"

"By the way, you are looking at the handlebar!"

After saying that, Sean turned up the picture of the handlebar inside the cab of the car.

Sean said: "Carl, look at this new scratch with blood stains, this place is still very clear! This is the only obvious place. The suspect should have worn thin gloves here, but his nails are too long!

"

Xie Yu nodded!

Officer Hunter interjected: "Senior Sean, this suspect's hips are a bit small, and her nails are too long. Do you think she could be a woman?"

Sean nodded and said: "I thought so too at first! Tao..."

Sean flipped through another photo of the footprints on the ground, enlarged it and pointed to the photo of a half-foot and said: "I looked at it for a long time. This half-footprint should belong to the murderer. Women don't have such big feet."

Hunter: "Could it be that small feet wear big shoes? This is a trick often used by many criminals."

Sean shook his head and said: "No, if you look closely, although the footprint is half, the force is even, there is no mark in the middle, and the cross section is clear. There is no big shoes on small feet like you said!"

"You can see that the density of the soil here is not hard, and if I try to step on it, it will leave a footprint of about one centimeter. The depth of the suspect's footprint is about three-fifths of mine. Counting this

Judging from the five-day loss rate combined with the geological density there, I judge that this person's weight is within 110 kilograms, within."

"Looking at the curvature around the shoe mark, we can roughly estimate the height of the murderer, which is between 1.73 and 1.76 meters."

Xie Yudao: "Is this the science of footprint identification?"

Sean said seriously: "Yes, this is the science of footprint identification. Carl, you have to learn it hard."

Xie Yu naturally replied: "I will work hard, Senior Sean!"
