Tiger Police

Chapter 100
"Look here, there are obvious gaps in the bones. And here, the gaps are tight. When Ding Ge returns to the bureau for further autopsy, there is a high probability that he can find metal fragments with missing blades from the bone gaps."

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

Wang Xiongjie had a look of approval on his face: "Not bad, the analysis is in place, let's continue."

"After the crime happened, at least two people came into the house before they were discovered and reported to the police today." Hu Pingtao turned around and pointed to the solidified black blood on the wooden floor: "This is the blood in the deceased's body, almost Drained. Except for what was absorbed by the sofa cloth, there was a large area of ​​blood on the floor, from here to the bathroom door."

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

Zhang Yixuan interrupted him unceremoniously: "Why must it be leather shoes instead of sneakers or sandals or slippers? There are so many styles of shoes, why do you make such a judgment?"

His tone was very blunt, but there was no malice, it was entirely out of the 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. 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 full of surprise, but he refused to admit defeat, and said with a sneer, "Haha... just blow it!"

Hu Pingtao did not argue, he said lightly: "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 to enhance The friction between the ground and the ground is stable and will not fall. It is the same as the pattern on the surface of a car tire. Generally speaking, the shoe shading is nothing more than three types: circular, angular, and linear. The difference It lies in the patterns cut out of different shapes, and the ups and downs at different positions of the sole."

"The shading is generally made of rubber, and there are also a small number of shoes that choose materials such as TPU and PU because of the requirements of quality and craftsmanship. Some brands use more expensive rubber brands in order to highlight their wear resistance. For example, Michelin and Continental, in It is used more in cross-country and outdoor shoes.”

"Sports shoes pay attention to the sense of grip. The mainstream of the shading is the technology and structure of the outsole rubber. This can reduce weight while increasing cushioning and rebound without losing grip and wear resistance. The shading of running shoes The design focuses on wear resistance, the flexibility of the forefoot, and the smooth transition. Among them, the difference between long-distance running shoes and sprinting shoes lies in the stability and power of the forefoot with different strengths."

"The shading design of basketball shoes is the most complicated. Generally, the longitudinal movement of running shoes and the lateral movement of training shoes must be combined, and the acceleration of the forefoot and the grip and wear resistance of the inner thumb position must be considered."

"Leather shoes pay attention to the style, especially the pad between the waist and the bottom of the shoe, which is the key to ensuring the stability of the shoe shape. Most leather shoes have a heel, which can improve the cushioning and heat insulation of the sole. Therefore, the sole design of leather shoes focuses on Stability, as well as the normal range of grip under normal walking conditions, 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 the bill by the way. I know you are a local tyrant, hehe...continue."

Hu Pingtao has long been used to Wang Xiongjie's habit of joking during working hours.He took a few steps to the right, pointing to the footprints solidified in the middle of the black bloodstains on the floor: "These three footprints are connected together, the distance between the first and the second is the largest, just the normal span of an adult man. The distance between the second one and the third one was only one-third of the previous one, which means that after the man came in, he saw Zhu Yajun lying on the sofa covered in blood at the intersection of the corridor and the bathroom."

Zhang Yixuan listened very carefully, followed Hu Pingtao's explanation to start thinking, and nodded slightly: "He wanted to confirm Zhu Yajun's state at that time. 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 around the coffee table. There are four footprints left on the left side. Judging from the position and distance, he stayed here at that time, then turned to walk The bathroom. One, two, three, four... There are a total of five footprints on this line, and eleven if you add the ones in the bathroom. But there are only footprints that go in, and there are no footprints that come out."

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

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

"First: Found that Zhu Yajun was killed, why didn't he call the police?"

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

Hu Pingtao shook his head, pointing to the black dried bloodstain on the floor: "Look here, this footprint is right on the edge of the bloodstain, obviously it was left by Zhu Yajun after his death. If I were the murderer, if there was no special reason, I would never Stay at the scene, but escape as soon as possible. And even if there is some reason to stay, you will not stay where the corpse is."

"Although the corpse is highly decomposed, the clothes on it are intact. This shows that the deceased was not sexually assaulted before or after death, and the things in the room were not messed up. It doesn't seem like killing people for money."

"Secondly, judging from the location of the footprints, this man stopped by the coffee table after leaving Zhu Yajun's body. I find this action difficult to understand. Under normal circumstances, people who find the body will feel panic and then have Help-seeking mentality. Since it is not the murderer, there is no need to worry about the police. It is the most reasonable way to remove the responsibility from it. Since there was no call to the police at that time, why did you still stand by 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 left in the shortest straight line, but circled to the left 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 in the room was very strong."

Hu Pingtao objected to this: "This possibility is very small. Under the circumstances at that time, after being frightened, the brain would make a judgment of "leave as soon as possible". The tea table is on the left, although there is half a meter between it and the sofa. However, it is a potential obstacle, and in any case it is not more convenient than turning to the right."

Zhang Wenxuan said thoughtfully: "Maybe he did some things in that position, or some arrangements that benefited him?"

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

"That 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 bloodstains on the ground: "The second person came in a little late, maybe several hours after the previous one. He was also shocked by the dead Zhu Yajun, but he didn't approach Check, but fell down here."

On the floor, where the edge of the bloodstain was facing south, there was a large area of ​​scratches, and there were several bloody palm prints beside it.

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

Hu Pingtao squatted down, pointing to the blood stains piled up on the edge of the fall mark: "Look here, this is the mark caused by pushing back from the inside of the blood on the ground. Blood will coagulate, especially now that it is summer, when large areas The 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, and when he saw the corpse, he was terrified and wanted to go closer to confirm. But he didn't pay attention to his footing, so he slipped and fell."

"When he stood up, he had to support the ground with his hands, so he left a bloody palm print, and at the same time pushed away the semi-solidified blood that was not completely dried. Here, and here, the gap between the edge of the blood stain and the floor The adhesion effect is very strong, forming a black border. But these blood clots that are pushed out do not have a strong adhesion effect, and even gaps are formed between some positions and the floor."

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

In fact, these traces are very obvious. As long as they pass the detection and analysis, they can be found one by one in the subsequent case discussion meeting.

The police are not idiots. They have been in this business for a long time, and they can find problems from clues.

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

Received the police from the 110 command center, transferred to the criminal police team and the Eryuan Road Police Station, Wang Xiongjie led the team to the scene, called Liao Qiu to transfer, and Hu Pingtao rushed over... For more than an hour, this seemed to Wang Xiongjie, It was the biggest gap between him and Hu Pingtao.

We came early and looked around the scene of the crime.

Less than 10 minutes after Hu Pingtao came in, he had already analyzed the case clearly and logically.

Zhang Yixuan was also full of depression. He originally planned to tell the truth about the problems he discovered in the case discussion meeting, and enjoy the compliments and envious eyes from other people.

Unexpectedly, this little thought was instantly torn apart by the violent external force, and Hu Pingtao broke it with a few casual words, and added various questions that he had never thought of.

Why is there such a big gap between people?

Hu Pingtao seemed to be addicted, and continued: "The second person also didn't call the police. He fell and fled the crime scene in a panic without even caring about cleaning up the dirty blood stuck to his body."

Zhang Yixuan took a deep breath.This action was his habitual behavior after he was depressed, but he didn't notice that more unbearable stench was poured into the depths of his nostrils, which made him feel nauseous and convulsed.

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

"The murderer is very careful. At least until now, I have not found any traces of him at the scene." Hu Pingtao shrugged his shoulders: "Of course, he must have left fingerprints on the body of the deceased Zhu Yajun, but the body has long since decayed , I'm afraid it can no longer be extracted from the skin surface."

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

"I think it should be a multiple murder case." The smell was too strong, Hu Pingtao raised his arms and covered his nostrils wearing a mask with the back of his hands: "Only in this way can we explain why the two people who entered the room after the crime No one called the police."

He then added: "Of course, there may be other reasons. But the relationship between these two people and the deceased is very close and very familiar."

Wang Xiongjie turned sideways and glanced towards the door: "Is it because there is no sign of prying the keyhole?"

Hu Pingtao nodded: "The two entrants both hold keys, or they are lockpicking experts. I tend to the former. After all, there are not many people who eat "lockpicking" now."

"Acquaintances committed the crime..." Zhang Yixuan rubbed his chin with a puzzled expression: "That is to say, if the murderer is not Zhu Yajun's relative, he is a very good friend?"

Wang Xiongjie quickly made a decision: "Let's investigate this area first! As usual, when investigating relatives, one must also investigate the financial situation of the deceased, especially the main source of income. Zhu Yajun's unit...well, the Alice Appraisal Center Over there, I will leave it to Tang Yuan. Fatty Ding is busy this time, and the inspection of Gao Fu’s corpse is the most troublesome, and I’m afraid the detailed report may not come out this week.”

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

"You and Gu Dewei check the surveillance together." Wang Xiongjie said: "It's not like before, we have to look for witnesses everywhere. It's good to have surveillance cameras, especially the probes installed at the gate of the community, which saves us a lot of trouble. We just need to concentrate on searching Those who enter and leave this yard within half a month will do."

……

At eleven o'clock in the evening, the information collected from various sources began to gather.

Zhu Yajun is not the owner of Room 07, Building 30, No. [-], Dingyuan Road.The relationship between her and her family is not very good. She rented a house outside when she was working in the hospital. Later, she resigned and went to the Alice Appraisal Center. It may be that the lease period has not yet expired and she cannot move out temporarily.In order to go to work conveniently, she found a taxi driver and agreed to pay [-] yuan a month. He would pick her up at [-]:[-] every morning and take Zhu Yajun to the nearest subway station.
