    It was lunch time after the on-site investigation was completed. Brother Ming gave us 10 hours to process the physical evidence. The case meeting was scheduled to start at 12 o'clock in the evening.  In order to achieve initial results in the shortest time, we made a detailed division of labor. A Le and Pang Lei were responsible for the surveillance video investigation, Lao Xian handled the biological evidence, and Brother Ming handled the traces for me.

    With a reasonable division of labor, things can be done more efficiently, and the evening project meeting has been advanced by an hour.

    "Let me talk about the autopsy first." Brother Ming always got straight to the point. "The deceased had a sharp injury to the carotid artery. The wounds overlapped many times. There were resistance injuries on the back of the head and hands of the deceased, indicating that the deceased was injured when he was violated.  There was fierce resistance, and the suspect most likely killed him by accidental injury. By analyzing the digestion degree of the deceased's stomach contents, it was found that he was killed shortly after eating dinner, which is consistent with the confession of the deceased's husband, Hu Wenchang.

    "The body spots were concentrated on the back. He was lying flat when he died. Combined with the blood distribution at the scene, we rule out the possibility of moving the body. The time of death of the deceased is consistent with the time of the call. Combined with the physical evidence extracted by Xiaolong at the scene, the suspect committed the crime.  The time period can be determined to be within 4 minutes from 19:46 to 19:50. That¡¯s all I have for now, Jiao Lei, please tell me.¡±

    ¡°Currently, the community only has surveillance equipment near the south gate. We don¡¯t know the physical characteristics of the suspect yet. A Le and I just backed up all the surveillance videos for investigation, but there are no good results for the time being.¡±

    "Guoxian, please tell me."

    Lao Xian took out the report: "I extracted two kinds of biological evidence at the scene. The first one was the skin tissue inside the nails of the deceased, and I detected male DNA; the second one was the saliva spots on the cigarette butts, which also detected male DNA.  DNA, and the two DNAs match. But unfortunately, we currently cannot have detailed information about the DNA."

    After Brother Ming recorded it, he turned his attention to me.

    I nodded in understanding: "According to the shoe print analysis, the suspect is a male, about 1.75 meters tall, with a disabled left hand, medium build, young and middle-aged, walking with his right foot heavy, which means he likes to lean to the right when walking, as shown in  In terms of gait, his body is swaying to the right. According to the analysis of the shoe prints he left at the scene, he has no disability in his legs and is very conscious, ruling out the possibility of committing the crime after drinking." At this point, I reminded Pang Lei:  "Brother Lei, when you observe the video next, focus on those who walk normally and like to step to the right. If my guess is correct, the suspect is used to walking like a penguin."

    "Ok, no problem."

    I continued: "Through the sole pattern, I analyzed that the suspect was wearing the most common plastic-soled canvas shoes on the market, priced at about 35 yuan. The sole pattern was severely worn, and he had worn the shoes for a long time. Suspect  The man smokes Dujiang cigarettes worth three yuan and a half per pack, and his shoes are so cheap, so his clothes shouldn¡¯t be that expensive, Brother Lei, this is also the focus of the investigation.¡±

    "receive."

    "The last thing is the suspect's crime tool. Through analysis, the suspect may have wiped blood stains on the deceased's clothes after committing the crime. After measuring the blood stains, it was found that the knife used by the suspect was 6 cm wide, 40 cm long, and 40 cm long.  There are wrinkled blood marks everywhere. Through magnification observation, the blade has holes about 0.5 cm in diameter every 1 cm, which are arranged neatly. This is a feature that ordinary knives do not have, so I suspect that the crime tool used by the suspect should be homemade.  And the workmanship is rough, it¡¯s most likely a sharp blade wrapped with a layer of tape.¡±

    Brother Ming suddenly made a pause gesture to me: "Xiaolong, let me interrupt."

    "Well, Brother Ming, tell me."

    "Are the data you measured accurate?"

    "The suspect left complete blood marks on the deceased's clothes, which is absolutely accurate."

    "Okay, let's analyze it. The blade used by the suspect is 40 centimeters long. There is something wrapped around the handle of the knife that is difficult to measure. But no matter how big the package is, he must at least be able to hold it in the fist of a normal person, otherwise he will not be able to hold it at all.  . We calculate based on the minimum size of an adult¡¯s fist of 10 centimeters. Including the blade, the shortest knife used by the suspect is 50 centimeters. If such a long tool is held in the hand, it will attract some attention. "

    Brother Ming took a sip of water and moistened his throat: "Yunxi City has been relatively hot recently. The average temperature at night is around 25 degrees Celsius. Now the streets are full of summer clothes. Even at night, there are only clothes on the street.  Only older people will wear thin coats.

    "According to my analysis, the suspect can carry the tools of the crime with him and conceal others. Either he carries a backpack with him or hides it on his body. If he carries a backpack, combined with the penguin steps mentioned by Xiaolong, it will not be possible to identify him through the videoIt is difficult to analyze the characteristics of the suspect.

    "If the suspect is carrying it with him, he will either wear a long-sleeved shirt or insert the crime tool into his waist. Wearing a long-sleeved shirt is directional, and the principle is the same as a backpack. If it is inserted into the waist, the suspect must  If you keep your waist very straight, your upper body will look stiff when you walk, Jiao Lei, you need to take these details into account when checking the video."

    ¡°Brother Ming, you are the one!¡± Fat Lei gave a thumbs up in admiration.

    "Xiaolong, what else do you want to say?"

    "In addition, I also extracted a trace, fingerprints."

    "Fingerprints?"

    "Yes, on the deceased's mobile phone, I not only extracted Xia Qing's fingerprints, but I also found another fingerprint. The fingerprint was very fresh and was left by a male. We don't have the fingerprint information at the moment. Mobile phones are important to each of us.  , are relatively private tools and are rarely lent to others. It is probably no coincidence that I found a stranger¡¯s fingerprint on the deceased¡¯s mobile phone. I have reason to suspect that this fingerprint is most likely left by the suspect.  Down."

    "You mean"

    "From this we can get the suspect's motive for committing the crime." I interrupted Ale, "The deceased was killed after talking to his best friend on the phone. According to ordinary people's habits, after making a phone call, the mobile phone is either in the hand or in the hand.  It was just in his pocket. The clothes Xia Qing wore had deep pockets, and after making the call, he was walking outside the north gate. In this case, it was very possible that he had put his mobile phone away. As a property, if the mobile phone is suspected  Why would a person touch someone if his subjective motive is not to steal money? Combined with the suspect's difficult economic conditions, I suspect that his subjective motive is to steal money. As Brother Ming said before, he may have given up after manslaughter.  He fled the scene with the thought of stealing money. Therefore, according to my inference, this is a case of robbery and murder."

    "That's reasonable! It makes sense at the moment." Brother Ming nodded.

    "The scene of the crime is a community under construction. Who would go to the community with a knife to rob?" Pang Lei was puzzled.

    ¡°We have a few things that we need to do urgently.¡± Brother Ming¡¯s words silenced the conference room instantly.

    "The deceased's left hand was disabled, and the location he chose to commit the crime was also quite special. I will contact the criminal police team later and ask them to conduct an investigation in the community based on the physical characteristics of the suspect we have drawn, especially the workers at the construction site of the community."

    "Xiaolong, you have to figure out in a short time what kind of crime tool the suspect used and whether it is directional."

    "clear."

    "Jiao Lei, hurry up and analyze the video and see if you can find the suspect's image data."

    "OK."

    ¡°That¡¯s all for now, we¡¯ll try again when we get the results.¡± (Remember the website address: www.hlnovel.com
