"Look here, there are obvious gaps in the bones. And here, the gaps are tight. When Brother Ding returns to the bureau for further autopsy, there is a high probability that the metal fragments from the missing blades will be found in the bone gaps."

With Wang Xiongjie's sophisticated eyes, it is actually not difficult to see these details. Hu Pingtao knew that this was Wang Xiongjie's opportunity to speak to him, including to Zhang Yixuan and Ding Jian before. He always likes to joke, but he will not delay his work because of it.

Wang Xiongjie showed a look of approval on his face: "Yes, the analysis is very good, let's continue."

"After the incident, and before being discovered today and calling the police, at least two people came into this house." Hu Pingtao turned around and pointed to the black blood that had long solidified on the wooden floor: "This is the blood in the body of the deceased, almost

It drained away. Except for the blood that was absorbed by the sofa fabric, the blood stains on the floor were very large, flowing from here to the bathroom door."

"There are three footprints here. Judging from the traces, they should be from the same person." Hu Pingtao avoided the black blood and walked around the side of the coffee table: "Look, this is the unique cross-shaped mesh pattern on the bottom of leather shoes..."

Zhang Yixuan interrupted him rudely: "Why do they have to be leather shoes and not sports shoes or sandals or slippers? There are so many styles of shoes, why do you make such a judgment?"

His tone was very rude, but not malicious. It was entirely out of his habit of being cold and arrogant.

Hu Pingtao smiled nonchalantly: "There is a big difference between leather shoes and sports shoes, especially the shading. Each manufacturer has a design patent. Let's talk about these three footprints. Judging from the shading,

It should be a men’s shoe released by Aokang the year before last.”

Wang Xiongjie said in surprise: "Xiaohu, can you even see this?"

Zhang Yixuan's eyes were also filled with surprise, but he refused to admit defeat and sneered: "Haha... Just brag!"

Hu Pingtao did not argue. He said calmly: "This is the unique concave sole mesh pattern of "Aokang" men's leather shoes. The reason why shoes have various patterns on the bottom is mainly to enhance the

The friction between the ground and the ground remains stable and will not fall. Just like the patterns on the surface of car tires, it is the same. Generally speaking, shoe soles are nothing more than circular, angular, and linear. The difference

It lies in the patterns made by cutting into different shapes, as well as the ups and downs at different locations on the soles.”

"The soles are generally made of rubber, and a small number of shoes choose materials such as TPU and PU due to quality and craftsmanship requirements. Some brands use more expensive rubber brands in order to highlight their wear resistance. For example, Michelin and Continental, in

Cross-country and outdoor shoes are used more in variety.”

"Sports shoes pay attention to grip, and the mainstream of the sole pattern is the craftsmanship and structure of the outsole rubber. This can reduce weight while increasing cushioning and rebound without losing grip and wear resistance. The sole pattern of running shoes

The design focuses on wear resistance, flexibility of the forefoot, and smooth transition. The difference between long-distance running shoes and sprinting shoes mainly lies in the stability and power of the different forefoot forces."

"The bottom pattern design of basketball shoes is the most complex. It generally combines the longitudinal movement of running shoes and the lateral movement of training shoes, and takes into account the acceleration of the forefoot and the grip and wear resistance of the inside thumb position."

"Leather shoes pay attention to the style, especially the padding between the waist and the bottom of the shoe, which is the key to ensuring the stability of the shoe. Most leather shoes have a heel, which can improve the cushioning and heat insulation of the sole. Therefore, the design of the sole pattern of leather shoes focuses on

Stability, and the normal grip feeling when walking normally, rather than the instant stability like braking when running fast.”

Wang Xiongjie smiled and said: "When I buy shoes another day, Xiaohu, you have to go with me, be my consultant, and help pay for it. I know you are a wealthy person, haha... go on."

Hu Pingtao has long been accustomed to Wang Xiongjie's habit of joking during working hours. He took a few steps to the right and pointed to the footprints in the middle of the black blood stains solidified on the floor: "These three footprints are connected together. The first one is the same as the second one."

The distance between the two is the largest, which is just the normal span of an adult man. The distance between the second and the third is only one-third of the previous one, which means that after the man came in, he saw Zhu at the intersection of the corridor and the bathroom.

The runner-up fell on the sofa covered in blood."

Zhang Yixuan listened very carefully, started thinking along with Hu Pingtao's explanation, and nodded slightly: "He wanted to confirm Zhu Yajun's condition at that time. He was a little anxious, maybe out of panic, and didn't pay attention to the blood on the floor until he walked in and saw

After seeing Zhu Yajun's tragic situation and discovering blood on the soles of his shoes, he quickly moved away."

Hu Pingtao agreed: "Look here, the bloody footprints circled along the coffee table. There are four footprints on the left side. Judging from the position and distance, he stayed here, then turned and walked to

In the bathroom, one, two, three, four... there are five footprints in total on this line, including the one in the bathroom, there are eleven. But there are only the footprints that went in, and there are no footprints that came out."

Wang Xiongjie said seriously: "He went into the bathroom to wipe off the blood on the soles of his shoes to avoid being seen on the stairs after leaving."

Hu Pingtao stretched his arms: "This is a normal reaction, and it also raises two questions."

"First of all: Why didn't he call the police when he found out that Zhu Yajun was killed?"

Zhang Yixuan said: "Could this man be the murderer?"

Hu Pingtao shook his head and pointed to the black dried blood stains on the floor: "Look here, this footprint is right on the edge of the blood stains. It was obviously left by Zhu Yajun after his death. If I were the murderer, I would never do it if there was no special reason.

He stayed at the scene and ran away as soon as possible. And even if he had to stay for some reason, he would not stay where the body was."

"Although the body was highly decomposed, the clothes on it were intact. This shows that the deceased was not sexually assaulted before or after his death, and the things in the room were not messed up. It does not seem like he was killed for money and sex."

"Secondly, judging from the location of the footprints, this man stopped for a moment at the coffee table after leaving Zhu Yajun's body. I find this action difficult to understand. Under normal circumstances, the person who found the body would feel panic and then have

The psychology of asking for help. Since it is not the murderer, there is no need to worry about the police. It is the most reasonable way to take away the responsibility. Since there was no call to the police at the time, why did you still stand at the coffee table instead of leaving the scene of the crime as soon as possible? "

"Please note that this person did not turn around and leave in the shortest straight line, but detoured from the left side of the coffee table."

Wang Xiongjie turned his head and glanced at the window: "Maybe he wanted to get some air here. After all, the smell of blood was very strong in the room at that time."

Hu Pingtao objected to this: "This possibility is very small. Under the circumstances at that time, in fear, the brain would make a judgment of "leave as soon as possible". The coffee table is on the left, although there is half a meter between it and the sofa.

The distance is a potential obstacle, and it is not as convenient as turning to the right."

Zhang Wenxuan said thoughtfully: "Maybe he did something in that position, or made some arrangements that were beneficial to him?"

Hu Pingtao said seriously: "It may be that there is something on the coffee table that he must take away, forcing him to do this."

"It makes sense." Wang Xiongjie nodded and turned to look at the open door: "Xiaohu, tell me about the second person who came in after the incident."

Hu Pingtao walked to the front of the living room and pointed to the blood stains on the ground: "The second person came in a little late, maybe several hours apart from the previous person. He was also shocked by the dead Zhu Yajun, but did not come closer.

Check it out, but I fell down here.”

On the floor, at the edge of the blood stain facing south, there was a large scratch mark with several bloody palm prints next to it.

Zhang Wenxuan looked serious: "I can see this. When I surveyed the scene before, I already extracted the fingerprints left on the floor. But you said that the second person entered the room later than the first person. For what reason?

?”

Hu Pingtao squatted down and pointed at the blood stains piled up on the edge of the fall mark: "Look here, this is the mark caused by the blood on the ground pushing back from the inside. Blood will coagulate, especially now in summer, when large areas

Human blood flowing on the floor will condense on the surface within half an hour. This person came in late. He obviously didn't notice the blood on the floor. In addition, when he saw the corpse, he was frightened and wanted to get closer to confirm.

But he didn’t pay attention to his step, so he slipped and fell.”

"When he stood up, he had to hold his hands on the ground, so he left bloody palm prints. At the same time, he pushed away the blood that was in a semi-coagulated state and had not completely dried. Here, and here, between the edge of the blood stain and the floor

The adhesion effect is very strong, forming a black border. However, these pushed-out blood clots do not have a strong adhesion effect, and there are even gaps between some locations and the floor."

Wang Xiongjie and Zhang Yixuan looked at each other, but neither of them spoke.

In fact, these traces are very obvious. As long as they are detected and analyzed, they can be discovered one by one at the subsequent case discussion meeting.

The police are not idiots. They have been doing this for a long time and can detect problems from clues.

The key lies in the specific time when these problems are discovered.

After receiving the call from the 110 command center and transferring it to the Criminal Police Team and Eryuan Road Police Station, Wang Xiongjie led the team to the scene and called Liao Qiu to dispatch people. Hu Pingtao rushed over... It took more than an hour. In Wang Xiongjie's view, this

This is the biggest gap between myself and Hu Pingtao.

We came over early and took a look around the crime scene.

Hu Pingtao had only been in for less than ten minutes, but he had already analyzed the case clearly and logically.

Zhang Yixuan also had a depressed look on his face. He had originally planned to reveal all the problems he had discovered at the case discussion meeting and enjoy the praise and envious looks from others.

Unexpectedly, this little thought was torn apart by a violent external force in an instant. Hu Pingtao pointed it out with just a few words and added various questions that he had never thought of.

Why are the differences between people so big?

Hu Pingtao seemed to be addicted and continued: "The second man also did not call the police. He fell down and fled the scene of the crime in a panic without even bothering to clean up the blood stuck to his body."

Zhang Yixuan took a deep breath. This action was his habitual behavior after a decadence, but he did not notice that more unbearable stench was injected deep into his nostrils, which made him feel nauseous and make his stomach twitch.

"Since the second person didn't call the police, how do you judge that he is not the murderer?" Zhang Yixuan asked, suppressing the churning and stench in his stomach.

"The murderer was very careful. At least until now, I haven't found any traces he left at the scene." Hu Pingtao shrugged: "Of course, he must have left fingerprints on the deceased Zhu Yajun, but the body has long since rotted.

, I’m afraid it can no longer be extracted from the skin surface.”

Wang Xiongjie looked at Hu Pingtao: "Xiaohu, what is your preliminary conclusion on this case?"

"I think it was a multiple murder case." The smell was too strong. Hu Pingtao raised his arm and covered his masked nostrils with the back of his hand: "Only in this way can we explain why the two people entered the room after the crime.

No one called the police.”

He immediately added: "Of course, it may be for other reasons. But the relationship between these two people and the deceased was very close and very familiar."

Wang Xiongjie turned sideways and glanced in the direction of the door: "Is it because there are no signs of prying in the keyhole?"

Hu Pingtao nodded: "Both entrants hold keys, or are lock-picking experts. I prefer the former. After all, not many people are interested in "lock-picking" now."

"An acquaintance committed the crime..." Zhang Yixuan touched his chin with a puzzled expression: "In other words, if the murderer is not a relative of Zhu Yajun, he is a very good friend?"

Wang Xiongjie quickly made a decision: "Let's investigate this aspect first! The old rule is that while investigating relatives, you should also investigate the financial situation of the deceased, especially the main source of income. Zhu Yajun's unit...well, Alice Identification Center

Over there, I'll leave it to Tang Yuan to take charge. Fatty Ding is very busy this time, and the inspection of highly decayed corpses is the most troublesome. I'm afraid the detailed report may not be available this week."

Hu Pingtao asked: "Brother Wang, which part of the work am I responsible for?"

"You and Gu Dewei check the surveillance together." Wang Xiongjie said: "Now, no more than before, we have to look for witnesses everywhere. It is good to have surveillance cameras, especially the probes set up at the gate of the community. It saves us a lot of trouble. We only need to concentrate on searching.

As long as people come in and out of this courtyard within half a month."

…

At eleven o'clock in the evening, information collected from all aspects began to come together.

Zhu Yajun is not the owner of Room 502, Building 3, No. 107 Dingyuan Road. Her relationship with her family is not very good. She used to rent a house outside when she was working in the hospital. Later she left her job and went to Alice Appraisal Center. Maybe

The lease period has not expired and she cannot move out for the time being. In order to make it easier for her to go to work, she found a taxi driver and agreed to pay two hundred yuan a month. The taxi driver would pick her up at 7:30 every morning and take Zhu Yajun to the nearest subway.
