With the arrival of Deputy Director Jin of the Public Security Bureau, the conflict between Murong Shui and the anti-drug policeman Xing Ye temporarily stopped. Du Yongzhi followed Director Jin and said: "Jin Bureau, according to the 'death card' left by the murderer at the scene,
', we can determine that this case belongs to the same murderer as the previous murder case of Chen's father and son, so this case should be handed over to our criminal investigation detachment for joint processing."
Before Director Jin could express his position, Zheng Jianghu who was standing next to him said bluntly: "Jin Bureau, the deceased this time was the second boss of the Qian Bang Casino. The other casino has been secretly selling new drugs since this year. We have been responsible for this case."
Yes, so our anti-drug detachment should take over."
After listening to the speeches of the two detachment captains, Director Jin just smiled and did not make a statement. He just said to the two of them: "How about this, let's wait for the forensic team's identification results to come out first."
Now that Director Jin had said so, Zheng Jianghu and Du Yongzhi couldn't say anything else, but Zheng Jianghu seemed to be more concerned about this case. He crossed the cordon of the forensic team, walked carefully to Li Mengxue and asked:
"Director Li, did you find anything?"
Ever since Xingye was violent to Wen Sibao just now, Li Mengxue didn't have much favorable impression of Zheng Jianghu's overbearing style, but she was by no means the kind of woman who brought her personal emotions to work, so she pointed to the Audi driveway aside.
: "We have not found any fingerprints other than those of the deceased inside the vehicle yet."
"Were any of the items on the deceased's body or the vehicle missing?" Zheng Jianghu asked reluctantly.
Seeing Zheng Jianghu constantly interfering with Li Mengxue's work, Wen Sibao was not happy, so he also crossed the cordon, walked in on the muddy road, and said seriously: "Detachment Zheng, please don't interfere with the forensic team's investigation of the scene."
Work, please leave the scene immediately."
After all, Zheng Jianghu was one level higher than Wen Sibao. He said politely: "Officer Wen, I have already told you that our anti-narcotics detachment is in charge of this case. You are the one who should leave here now!"
"You two, get out!"
Seeing that the ground was trampled with footprints everywhere, Li Mengxue finally couldn't help it anymore, and pushed the two of them out of the cordon, and said to his apprentice Xu Wudi: "Wudi! Come and watch.
Both of them! Don’t let any of them in!"
"okay!"
Xu Wudi agreed, pulled up his pants and stood at the edge of the cordon, tilted his head and stared at the two people in front of him, suddenly pointed at Zheng Jianghu and scolded: "Your foot has crossed the line! Pull it back!"
Zheng Jianghu looked down and found that the marine boots he was wearing had stepped on the cordon. No matter how arrogant he was, he still had to be polite when facing a group of technicians from the forensic team. After all, he
Every now and then, the department has samples that need to be sent for inspection and identification. If the other party is really annoyed, there is no guarantee that the forensic team will deliberately wear small shoes for themselves at work, or prioritize the samples sent for inspection by their own department.
lowest.
When Zheng Jianghu thought of this, he immediately smiled and retracted his foot.
…
The next day, the Public Security Bureau held its first case seminar, and both the Criminal Investigation Detachment and the Anti-Narcotics Detachment also participated in the meeting.
Li Mengxue reported at the seminar on behalf of the forensic team: "The deceased Qian Er, male, 36 years old, according to a speed camera in the suburbs last night, the deceased drove the Audi car into the city that night, and was also caught by the speed camera.
The surveillance footage was taken."
Li Mengxue put a slide into the projector nearby, and Qian Er's arrogant look with his middle finger raised suddenly appeared on the screen, causing everyone to burst into laughter.
Li Mengxue explained: "This is a picture of the deceased captured by surveillance at around 11 o'clock last night. It can be seen that there was no one else in the car at that time, so we speculate that the deceased was stopped and killed by the murderer on his way to the city.
But unfortunately, the road into the city is a remote section, so there are no cameras to capture the murderer. There are 5 intersections to the north of that road that lead to the city, and only 2 of them have surveillance coverage.
If the murderer was familiar with the city's surveillance environment, he could have driven the Audi into the city while avoiding surveillance, and then drove through various lanes and side roads to the 14th Company on the west side of the city."
After Li Mengxue finished speaking, he covered a transparent slide with several red lines on the city map, and several red-marked routes suddenly appeared on the city map on the screen.
Li Mengxue explained: "After the judgment of our colleagues in the trace team, if the murderer hijacked Qian Er's Audi, there are a total of 9 routes that can avoid surveillance and reach the 14th company. Therefore, if we want to find the movement track of the Audi, we must follow the red line
Visit all businesses within the range shown to see which ones have 24-hour surveillance equipment in front of their doors."
"Financial Bureau, we are responsible for monitoring the merchants along the way." Zheng Jianghu did not wait for the other party to finish speaking, and directly and unreasonably took the matter into his own name.
Wen Sibao and the other police officers from the criminal investigation detachment watched helplessly as such an important clue was snatched away by the anti-narcotics detachment. They had no choice but to gesture to Du Yongzhi with their eyes, as if making a silent protest.
Li Mengxue changed a new photo in the projector and explained.
——"This is a photo of the crime scene of the deceased. At the time of the crime, the deceased was kneeling and died at the door of a villager in the 14th company. The fatal injury was an 18cm long dagger inserted into the head. This kind of dagger is very common.
, can be purchased at any grocery store or roadside stall. At the same time, judging from the degree of blood splatter around the deceased, the location where the deceased was found was the scene of the first crime."
——"The corpse was discovered at 9:35 in the morning. At that time, the corpse already had the characteristics of generalized rigor mortis. The corpse spots did not fade but had not reached the spreading stage by acupressure. Therefore, it was consistent with the generalized rigor mortis in the sixteen processes of the corpse.
According to the dead period, it is estimated that the time of death was between 2 a.m. and 3 a.m. the day before."
——"There are four symmetrical micro-focus marks on the lips of the deceased, which are suspected to be electric shock injuries caused by electric shock rods. In addition, there are restraint injuries caused when the hands and feet of the deceased were tied. There are no resistance injuries in other parts of the body, so we judge that the deceased
At that time, he was beaten in the mouth with a stun gun by the murderer until he was unconscious and then tied with a 3cm rope. There was no physical conflict with the murderer after that."
Zheng Jianghu was the first to say: "It seems that the situation is very clear. The murderer kidnapped Qian Er on an unmonitored road section, then stunned him with an electric shock stick, and then drove the deceased's car in a way to avoid surveillance along the way.
The Fourteenth Company later killed the deceased, and this series of actions had an obvious vendetta nature."
"Yes." Li Mengxue added: "The deceased Qian Er was the deputy general manager of Mobei Bank Small Loan Company and was responsible for the collection of accounts. According to the police in the jurisdiction yesterday, Qian Er once asked someone in a casino
A man named Li Qiang provided new drugs, and later Qian Er tricked Li Qiang into a gambling habit. In the end, Li Qiang couldn't bear the violent collection of money and committed suicide. At the same time, in the city's crime report records, only bank loans this year were
The company has dozens of records of cases it has accepted, and this does not include cases where victims failed to report the crime."
After Li Mengxue finished speaking, he replaced a new slide, which showed several needle holes on the body of the deceased Qian Er, and explained: "There is another point worth noting, that is, when we performed an autopsy on the deceased,
, in addition to the fatal stab wound on the top of the head, there are fresh pinholes of varying degrees throughout the body."
As soon as the word "pinhole" was uttered, the members of the anti-drug detachment immediately became alert.
Li Mengxue explained: "According to comparison by the forensic team, the needle holes on the body were caused by the No. 7 hypodermic syringe commonly used in hospitals. There were 5 needle holes in total, one on the deceased's occipital bone, the lower side of the cervical spine, the coccyx, the lumbar spine and the inside of the groin.
"
Zheng Jianghu asked hurriedly: "According to Director Li, the deceased was still a drug addict?"
Li Mengxue shook his head and said: "I'm afraid not. Although we found pinholes on the body of the deceased, the toxicology test on the deceased was negative."
Zheng Jianghu asked again: "Did the deceased take some kind of new drug and thus deceive the toxicology test of your forensic team?"
Li Mengxue explained: "Detachment Zheng, the commonly used toxicology testing methods on the market now are to test human urine, blood, nails, hair, etc. The general principle is that when toxic components enter the metabolism, they will remain in the keratin.
The detection of ingredients is a chemical test, but this time we have a more intuitive method in addition to these conventional methods for the deceased."
Zheng Jianghu asked: "What method? Can it be guaranteed to be 100% accurate?"
Li Mengxue frowned, as if she didn't like what the other party said, but she still patiently explained: "Detachment Zheng, for the medical profession from ancient times to the present, there is only one hundred percent, and that is that people will die 100% of the time. In addition,
Any test can only infinitely improve its accuracy, but even if the test accuracy has countless 9s after the decimal point, we cannot guarantee you a 100% accuracy rate."
Zheng Jianghu obviously didn't understand these words, so Li Mengxue explained directly: "In words that everyone can understand, it is that different drugs cause different damage to the human body's organs, but regardless of whether the deceased has taken any kind of drugs,
As long as we cut open the brain, heart, liver, lungs and other organs of the deceased and directly observe the degree of tissue disease in these organs with the naked eye, we can draw conclusions. Therefore, judging from the autopsy of Qian Er by our forensic team this time,
The other party has not taken any drugs."
After a moment of silence, Wen Sibao suddenly asked: "According to the forensic team's test, were the pinholes on the deceased's body caused by the deceased's self-injection of drugs? Or were they forcibly injected with some kind of drug by the murderer?"
Li Mengxue said: "Based on the degree of scabbing on the pinhole, it is very likely that it was left during the time when the deceased was held hostage by the murderer, but... we will detect any drug components in the blood of the deceased in the future."
The needle was forcibly injected, but no medicine was injected. This situation also made everyone in the conference room feel confused. Someone in the crowd even suddenly said: "Did the murderer inject some kind of biochemical virus into the deceased?"
The unknown always makes people frightened. After hearing this, everyone also showed a look of horror. You and I started to speculate, which instantly amplified the murderer's "conspiracy theory" infinitely.
"Quiet, quiet."
Director Jin saw that the scene was getting more and more chaotic, so he motioned for everyone to be quiet.
After the conference room became quiet, Director Jin explained: "Everyone should already know the general situation of the case. The first thing we want to find out now is how the deceased drove the Audi car into the crime scene that night.
What is the relationship between him and the murderer? Did he commit the crime in a gang? Or did he commit the crime alone? Finally, the forensic team must find out what kind of drugs the murderer injected into the body of the deceased during the murder. Try not to miss any detail of the crime scene.
.”
Suddenly, a phone ring rang in the conference room, and everyone looked in the direction of the ring with displeased expressions, wanting to see who the person who was breaking the rules of the meeting was.
Xu Tiannan, who had never expressed any opinions since entering the conference room, stood up, smiled apologetically at everyone, and explained: "I'm sorry, everyone, this is a call from a student. I'm out.
Take it and be right back."
After Xu Tiannan walked out of the conference room, he walked quickly into the distance, but not long after, he only heard the footsteps that had just gone away, and sounded from another door of the conference room, getting closer and closer, and then everyone
I heard Xu Tiannan's voice answering the phone, "What are you doing? I'm in a meeting at the Public Security Bureau!"
It turned out that after Xu Tiannan walked out of the conference room, in order to get further away, he simply walked to the end of the corridor and then turned to another corridor of the building. Little did he know that there were doors on both sides of the conference room, and Xu Tiannan was standing in the conference room at this time.
There was a phone ringing at the door on the other side of the room.
——"Hello? What are you three doing? Didn't you tell me not to call me before I go back?"
Xu Tiannan was only separated from everyone by a door at this time, and his voice came in very clearly. Zheng Jianghu looked very unhappy and ordered to Xingye: "Go out and talk to him, and ask him to call and stay away!"
"Hey! Xiao Zheng!" Director Jin lowered his voice and said, "Teacher Xu is our external criminal investigation expert, and after all, he is a guest. It seems so rude of you to do this. Tell Xingye to sit back."
Zheng Jianghu nodded and motioned for Xingye to sit back in his seat. As a result, everyone in the conference room had to sit quietly, waiting for Xu Tiannan to finish the call.
——"What? Case? What case! Let me warn you three. Before this case is concluded, I will not reveal any stories related to the case to you. Give up!"
Director Jin smiled and whispered to everyone: "Look, this guy is quite principled."
But soon, Xu Tiannan's voice came in again very clearly.
——"Go back to school? How do I know when I can go back? It was tiring enough to have two idiots named Wen Sibao and Li Mengxue, but now there is another big idiot named Zheng Jianghu, and these three people insist on it.
The whole case has gone astray!"
In the conference room at this time, Wen Sibao, Li Mengxue and Zheng Jianghu looked as ugly as bitter gourds. Director Jin also whispered to Xingye: "How about... you should go out and remind me?"
——"Okay, okay, let's not talk anymore! I have to go back and organize my language to see how I can say it without hurting these people's little self-esteem. That's it, I'm done!"
After hanging up the phone, Xu Tiannan's footsteps gradually faded away, but soon, the footsteps came back from far and near. He opened the door of the conference room, smiled at everyone and said: "Sorry, everyone, students.
The parents came and we chatted a few more words on the phone, eh?"
Before Xu Tiannan finished speaking, he felt that the atmosphere in the entire conference room suddenly became very strange, so he asked Murong Shuidao in a low voice: "Shui Gen, what happened to these people?"
