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 also 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 blood stains, but he didn't see anything!
Sean knew that Xie Yu didn't notice, so he didn't pretend. Instead, he drew an arc on the photo with a pen and said, "Karl. Do you think this looks like a person's buttocks?"
Based on 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 The blood-stained covering!”
"But if that's the case, shouldn't there be more obvious breaks in the blood stains?"
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 also very absorbent. When the suspect left the car seat, the blood stains on his buttocks would naturally spread."
"However, you haven't been on the police for a long time, so it's your fault if you can't tell!"
"By the way, you're looking at the handlebar!"
After saying that, Sean turned up the picture of the handlebar in 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 were 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! Said..."
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, take a closer look at the footprint. Although it is half a footprint, the force is evenly distributed. There is no mark in the middle. The cross section is clear. There is no big shoe on a small foot like you mentioned!"
"You can see that the density of the soil here is not hard. 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, which is 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 Yu said: "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!"
Sean nodded and continued: "This is still my inference. Come on, I will take you to find the evidence. If you find the evidence, you will believe it!"
