The door of the pretrial room was gently pushed open, and Xu Tiannan stood outside and waved to Wen Sibao.
"Give you some time to think about it!"
Wen Sibao said these words with a cold face, and then walked out of the house, only to hear Xu Tiannan say: "Fourth Master, I'm afraid you arrested the wrong person this time."
Wen Sibao also looked embarrassed and said: "To tell you the truth, I feel the same way. A social gangster like this who works in engineering can bully people, but killing people... I don't think he has the guts."
"But..." After Wen Sibao finished speaking, he changed the topic: "But all the clues we have collected now point to this kid. Look at his height and shape, clothes, pants, and his face.
The beard is obviously consistent with the description of the scavenger in the interview. What is going on?"
"You should take a look at this first and then talk about it."
Xu Tiannan motioned to Li Mengxue to take out the two solidified plaster models of shoe prints, put them under the light, and asked, "Do you still remember the golf bag that was lost at the murder scene?"
Wen Sibao nodded, "I remember, after Liu Jianmin's driver checked the room, he found that in addition to the missing golf bag, there was also a bone chopping knife missing in the kitchen. The murderer should have used that knife to chop him down.
The secretary's hands."
"Then take a look at this again."
Xu Tiannan opened the golf bag sales website on the mobile web page again, where there was a details page showing all the items in the golf bag.
This kind of high-end product will have detailed pictures and photos of each item, so Xu Tiannan quickly found the detailed pictures of the pair of golf shoes and said to Wen Sibao: "Compare the soles of this pair of sneakers with our plaster
Model."
Wen Sibao picked up his mobile phone and compared it with the plaster model of shoe prints under the light. He immediately discovered the clue and said in surprise: "How can the sole pattern of this model be consistent with the sole pattern of that pair of golf shoes?"
"That's exactly what I meant."
Xu Tiannan took out a ruler, measured the length of the plaster shoe print, and then explained.
——"Look, the model of this pair of plaster shoe prints not only has the same sole pattern as the pair of sneakers in the golf bag, but even the shoe size is correct, they are both size 44 shoes."
——"So I guess that after killing Liu Jianmin, the murderer put the bone-chopping knife and the female secretary's hands into the golf bag and took them away."
——"But I think the murderer's state when he left was that he had changed into the clothes and shoes from Liu Jianmin's golf bag before leaving."
Wen Sibao asked: "I can understand that the murderer took away the female secretary's hands and the bone chopping knife, but why did he take away Liu Jianmin's clothes and shoes?"
Xu Tiannan took out several photos taken at the crime scene tonight. Although the body surface of the deceased in the photos was extensively burned, and some parts were even scorched, the female secretary's severed hand could still be vaguely seen.
The cross-section of the wound is unusually rough.
Later, Xu Tiannan explained.
——"Look at the skin and flesh of the female secretary's broken hand. Not only are there multiple jagged scars at the break, but also the impact injuries from multiple knife cuts can be seen on the broken bone."
——"Look at the messy wounds on Liu Jianmin's head."
——"It is not difficult to see that the murderer is not skilled in such behaviors as hitting people on the head with heavy objects and amputating limbs at the murder scene."
——"So Fourth Master, do you think that a murderer like this who is not skilled in killing and amputation would leave blood stains, fingerprints, and shoe prints everywhere on the crime scene?"
——"Even when the murderer was doing something like amputation, he couldn't accurately predict the direction of the blood splatter after the knife was cut, so he ended up with blood stains all over his body?"
Wen Sibao suddenly realized: "I understand! When the murderer was doing these things, he must have made the house full of blood, and the clothes and shoes he originally wore must have been stained with a lot of blood from the scene! So he needs
Put on some clean clothes and leave so you don't attract attention."
Xu Tiannan nodded.
——"The above is just my guess, but I think that a murderer who is not skilled in murder, dismemberment and other murder methods will more or less be stained with blood during the murder."
——"Therefore, for the murderer at that time, he would definitely not leave wearing bloody clothes, as that would be too conspicuous. However, we know that the murderer committed a passion killing this time, so he would definitely not prepare clothes in advance."
——"Then after the murderer commits the crime, the best way is to put on Liu Jianmin's clothes and shoes directly, so that he will not be less noticeable on the way out, and at the same time, he will not leave his bloody shoes on the ground.
Printed."
At this point, Xu Tiannan suddenly changed the subject and said: "However, the murderer made a fatal mistake. That is, he may have deliberately left two leaves in the flower bed at the door for the purpose of misleading our police investigation direction.
A shoe print."
Wen Sibao: "Well, you are right. I also think that the murderer's method of misleading our police is a bit unscrupulous. He wants us to mistakenly think that the murderer is a man wearing size 44 shoes, thus confusing our police.
, but for now, at least I have mastered two things."
Xu Tiannan: "What two things?"
Wen Sibao: "First: Since the murderer wants to mislead us into thinking that he wears size 44 shoes, then his foot shape must not be size 44. Second: The murderer's real shoe size is smaller than size 44, because only small feet can wear larger sizes.
Shoes, big feet can’t fit into small shoes.”
After finishing the above analysis, Wen Sibao looked at Xu Tiannan with a hint of satisfaction, and whispered: "Well, I finally caught up with your thinking this time, right?"
"Well, not bad."
While Xu Tiannan was praising the other party in a low voice, he told the police officer in charge of recording next to him: "So the murderer we are really looking for this time should be a famous person wearing ordinary clothes and not outstanding, with a height of about 1.73-1.75 meters."
A male, weighing approximately 70-74 kilograms. The person's face, neck, chest or arms and other naked skin outside clothing should have obvious scratches. As for the person's shoe size, it is estimated to be
Between 41-42 yards, it will not exceed this range."
Wen Sibao was stunned. It turned out that the other party had already mastered so much information about the murderer, so he hesitated and said: "Huh? Tiannan... Are your portraits of the murderer accurate to this point?"
Xu Tiannan did not answer, but took out a photo, which was the photo taken from the flower bed at Liu Jianmin's door, and explained: "Just when you arrested the guy named Zhang Tufang tonight, we had already tested that
The density and load-bearing capacity of the soil in the flower bed, and later based on the depth of the shoe print in the soil, led to clues that the murderer was about 90 kilograms."
Wen Sibao said in surprise: "But you just said clearly that the murderer's real weight should be 70-74 kilograms?"
"Because I have to subtract this."
As Xu Tiannan said, he opened the official website of the golf equipment again, and saw that the details page of Liu Jianmin's golf bag clearly showed that the curb weight of the entire set of equipment was 16 kilograms.
Wen Sibao suddenly realized: "Oh! I understand, the murderer must have been carrying that golf bag when he left, so based on the 90 kilograms you calculated, you need to subtract the 16 kilograms of the golf bag to identify the murderer.
Real weight."
"Yes, this is how to calculate the murderer's weight. Now let's take a look at his height."
Xu Tiannan took out a photo of the scene, and this time the photo was a photo measuring the distance between two shoe prints, which clearly showed that the heel distance between the two shoe prints was 84cm, he explained.
——"Based on these two shoe prints, we can measure the murderer's stride length to be 84cm."
——"When the human body walks normally, the stride length is about 45% of the height, but for this murderer, we cannot use this data to judge."
——"Because this is most likely the murderer's first murder, he must have been panicked when he just left Liu Jianmin's villa."
——"Since he was in a panic, his stride length when walking would be 3%-5% longer than when walking normally, so we can conclude that the stride length collected at the scene was about 48% of the murderer's height.
"
——"To sum up, it can be inferred that the murderer is about 1.73-1.75 meters tall."
Wen Sibao understood completely now, and then added: "So after we know the approximate height of the murderer, we can also deduce the common shoe size for people with this height."
"Yes, the data we have inferred now are only based on a normally developing male." Xu Tiannan then changed the subject and said: "Maybe one day, when we really catch the murderer, we will find out the murderer's actual identity.
The picture will be very different from what we speculate now, but at least one thing is certain now."
Wen Sibao: "What is it?"
Xu Tiannan explained: "The scavenger interviewed by Huahua News this time should know the murderer, and the reason why he mentioned so much information in the interview that was completely contrary to the murderer's portrait, I think he should be protecting the murderer.
.”
Wen Sibao: "Well, I have thought about what you said. Regardless of whether this scavenger is telling the truth or a lie, the top priority now is to find this person. I have asked the local police station to find the scavenger.
, but according to the news from the police, that person has never returned to his shabby shack since the incident. After all, this kind of person lives in no fixed place every day. It is probably necessary to find him now.
Take some time."
As soon as he finished speaking, the sound of women quarreling suddenly came from outside the porch of the pre-trial room.
"Vixen! Bastard!"
"Fart! You are the vixen!"
As a crisp slap came, no one knew who hit whom, but in an instant, the entire pretrial room hall was filled with the shouts and curses of the two women fighting each other.
Wen Sibao immediately led someone out and found a middle-aged woman wearing an expensive designer suit who was pushing a young-looking girl to the ground and slapping her hard.
.
The middle-aged woman was very strong, and when she hit her, it was as if she was possessed by the god of war. Several young police officers tried to pull her away, but they couldn't hold her back. When she was finally pulled away, she had to attack the young woman before leaving.
He added a fierce kick.
"Stop it! Do you know where this place is? How dare you come here to cause trouble!"
Wen Sibao shouted loudly, and then stopped the two women in front of him. He asked the police officer on the side: "What happened?"
The police officer beside him explained with a grimace: "Didn't we arrest a suspect named Zhang Tufang today? That kid finally told the truth just now. During the time when Liu Jianmin died last night, he had been having sex with his lover.
mixed together."
Hearing this, Wen Sibao's heart sank. It seemed that what he and Xu Tiannan had just analyzed was correct. Zhang Tufang was indeed not suspected of committing a crime. It was indeed the rag picker who had lied about this matter.
The police officer added: "So according to the procedures at that time, we needed to ask Zhang Tufang's lover to come and testify to prove that Zhang Tufang did have an alibi when the murder occurred, but we didn't expect that... Zhang Tufang's wife also knew about it somehow.
After hearing about this incident, I rushed here in a hurry just now. But what happened now is that my wife and the mistress bumped into each other directly... and then, just, just... they started fighting!"
"Look at what you've done!"
Wen Sibao glared at the other person and walked forward to check the injuries of the two women in front of him.
The tall and thick middle-aged woman's clothes were dirty and her hair was a little messy, but another young and thin woman had her glasses broken at this time, her face was red and swollen, and her nose was bleeding.
on clothes.
Wen Sibao sternly reprimanded the tall and stout woman: "How courageous are you? If you dare to hit someone in the public security bureau, look at the injury the other person received. If it is determined to be a minor injury, you will be held criminally responsible."
have no idea!"
The middle-aged fat woman was obviously frightened. She was trembling and did not dare to look directly at Wen Sibao, but she was still unconvinced and argued: "But...but this vixen..."
"But what!" Wen Sibao interrupted the other party seriously: "Even if you are Zhang Tufang's wife! After discovering that he cheated, what you need to do is go to the court to file for divorce! Instead of directly using violent means to solve the problem
Question! Do you understand?"
As soon as these words came out, the scene suddenly became quiet, and the two women in front of him looked at him with surprised eyes. Wen Sibao thought about it carefully, he didn't say anything wrong just now? Why are he looking at him like this?
Own?
After a while, the police officer who broke up the fight came over and whispered: "Detachment Wen, what you did... you made a mistake... you made a mistake..."
The police officer pointed at the young girl who was beaten and whispered: "She is Zhang Tufang's first wife..."
Then, the police officer pointed at the tall, middle-aged woman and said, "She is the mistress..."
