time-limited arrest

Yu Su took Lin Huaiyue into the meeting room and left. Lin Huaiyue felt that sitting was boring, and saw a whiteboard in the meeting room, on which were written the identity information of the four deceased.

"No.1 The deceased Fang Kang, male, 36 years old, was a courier in a logistics company. The person who saw Fang Kang last was his colleague. He said that Fang Kang would ask for half a day off every Friday afternoon, so the last time he saw Fang Kang was nine days ago. before."

"The forensic doctor estimated that the time of death was no less than eight days and no more than ten days, so the death of the deceased was shortened to eight to nine days." Yu Su, who had just left, returned and handed Lin Huaiyue a glass of water while speaking.

Lin Huaiyue knew that Yu Su hadn't accepted the hot temperature for the time being, but holding the cup of lukewarm water in his palm did warm him up a bit. He looked at the name on the board and asked, "What's the specific cause of death?"

Yu Su summed it up briefly, "Fang Kang died of kidney rupture and excessive blood loss due to stab wounds. After his death, his head was cut off in the warehouse of Yuesheng Hotel, and the head was replaced with flour. After inspection, it was used in the back kitchen of your hotel. It's the same kind."

Lin Huaiyue responded, this matter was within his expectation, he looked at the clipboard and muttered to himself, then pulled out the marker pen and marked the first case: "Flour, warehouse, five-horse body, head."

Seeing Lin Huaiyue making a mark, Yu Su said, "No. 2 deceased Huang Le, male, 23 years old, a gangster, the Taoist called him Huang Mao. Huang Le disappeared these days, and his cronies thought he was running away from gambling debts. I went there, didn't take it seriously, and didn't know that he had died. The forensic doctor estimated that the time of death was about 5 days, which matched the confession of Huang Le's friend."

The cause of death had been written on the board. Lin Huaiyue looked it over and found that the deceased was half-buried in a flowerbed in the park. The murderer used flour to replace the deceased's hands.So he also marked with a marker: "Flour, half buried in the soil, both arms."

As if he had found a tacit understanding, Yu Su then mentioned the No.3 deceased, "The deceased Feng Fu, male, 42 years old, a street cleaner in the community, died three days ago. The murderer used tools to chop off the deceased's hands and feet. with the head, thrown in the trash, and took the body of the dead."

Lin Huaiyue also marked "flour, throw in trash can, body".

"Not enough." Lu Ci said, walked into the conference room, put a stack of reports on the conference table, tapped on the whiteboard with No. 3 deceased's identity information and said, "The box sent by the murderer Among the remaining limbs, the body of No. 3 deceased had no internal organs, and was completely removed."

"The autopsy report came out?" Seeing Lu Ci appearing, Yu Su reached out to pick up the report on the table and flipped through it.

I saw in the report that No. 3 man Feng Fu had a [-]cm vertical incision on his abdomen. The body was only a shell, the internal organs were all hollowed out, and there were traces of pulling on the top of the organs. It should be the murderer. Pull out the viscera and then resect it to rule out the possibility of organ|official|trafficking|selling.

"The technique is clumsy, and skilled hands are ruled out." Yu Su carefully looked at the photos posted on the back, and some of them were photos of visceral fluids that caused the organs to rupture and flow out due to forceful removal.

"Mr. Lin, tell me..." Yu Su said, turning his head to look at Lin Huaiyue. He saw that he had been staring at the writing board, deliberately not looking at him, so he snickered knowingly, and put the report in his hand on the On the one hand, he said to Lin Huaiyue, "Do you think the murderer deliberately removed the deceased's internal organs for what purpose?"

Lin Huaiyue's eyelids drooped slightly, and her slender eyelashes trembled slightly. When she heard Yu Su's voice, she turned her head to look at him, and said two words: "Hate."

Human behavior is dominated by motivation, and motivation is caused by human needs, and motivation cannot be generated without needs.And there is a need to produce, but also an incentive condition.

To put it simply, the reasons for criminals to kill are firstly the internal conditions of self-needs and desires, and secondly, external temptations and stimuli.

The criminals in this case committed serial crimes, and the purpose is already obvious. He was motivated by the contact with or trafficking of drugs by the four deceased. It can be seen that the emergence of drugs touched his interests, so he Only then should the contradiction be brought to the deceased.

The murderer deliberately used flour that looked like drugs to replace the heads, limbs, and bodies of the four deceased, in order to tell the police that these people were engaged in drug trafficking, and only the deceased whose head was removed, Fang Kang, was written "" I am guilty" three words, obviously the murderer hated these people very much, he just hoped that this matter would become a big issue and let the police intervene in the investigation.

Qi Yi knocked on the door, probed in and asked, "Captain, it's time, can we come in for a meeting?"

Yu Su nodded, pointed to the seat next to Lin Huaiyue to sit first, and walked aside with the autopsy report to discuss with Lu Ci.

It wasn't until everyone sat down that the technical detectives arrived late.Chief of Physical Evidence Section Wu Tao knocked on the glass door of the meeting room and walked in, met Yu Su face to face, then looked at the people in the meeting room and asked, "Who is forensic doctor Lu?"

"The inspection report for that piece of rubber came out?" Lu Ci said, craned his neck towards the report in Wu Tao's hand.

It was only then that Wu Tao noticed the little brother beside Yu Su, raised his eyebrows and said hello, "You are the forensic doctor Lu?"

It's all because Yu Su is too tall like a sky-swapping monkey, and it seems that Lu Ci standing next to him is very petite, and basically has no sense of existence.

"The result came out. The characters on it were repaired and read "Antai Psychiatric Rehabilitation Center". The blue bracelets belonged to medical staff, the yellow bracelets belonged to staff members, and the green bracelets belonged to patients." Wu Tao said, I turned to the last page and showed them that the bracelet repaired by the computer was the same as the bracelet found in the Antai Psychiatric Rehabilitation Center.

Lu Ci frowned, "Is the deceased a mental patient?"

Hearing this, Yu Su pursed his lips, "Fang Kang's worker said that he would ask for leave every Friday. Could it be to go to the hospital?" He said, looking at Gu Li.

Gu Li understood, and immediately contacted Antai Psychiatric Rehabilitation Center to confirm whether Fang Kang was a patient, but the answer given by the other party was negative.

The police system cannot check the information in the hospital. Gu Li can only rely on the verbal information of the hospital, and replied to Yu Su: "The rehabilitation center said that there is no such patient as Fang Kang. After the meeting, people will have the death certificate of the deceased. Go over there and check again."

"Okay." Qi Yi responded, and recorded the matter in the meeting minutes.

"The autopsy reports of the first three deceased are all out, what about Li Tian's autopsy report?" After finishing one topic, Yu Su immediately brought up the next one. The time was tight and they didn't have much time.

No.4 The deceased, Li Tian, ​​was 28 years old, currently unemployed, relying on family support to hang out in bars and Internet cafes all year round, only eating, drinking and having fun.The task force investigated his personal relationships. According to his parents and friends, Li Tian had been earning a lot of money since half a year ago, but he never mentioned where he worked.

The forensic doctor handed in the report and said: "The deceased had a ruptured femoral artery and died of excessive blood loss. In addition to frostbite on the body surface, there was a strangle mark on the neck. He had signs of struggle during his lifetime. We found skin tissue in his nails. At the same time, we detected anesthetics in the respiratory tract of the deceased, and found 50 grams of K| powder on him, but he himself did not take drugs."

The fourth case is the murderer's most sloppy case. Compared with the previous cases, this case is full of loopholes.

Qi Yi was overjoyed, "We have found the skin tissue of the murderer, we have made progress!"

Lin Huaiyue was not surprised. The murderer knew that his goal had been achieved, and the police had already noticed the case. His next goal was to kill his enemy and end his hatred, so it didn't matter whether the last case was perfect or not.

"There are new discoveries." Gu Li said, connected his computer to the projection screen in the conference room, and played two surveillance clips.

Two sections of surveillance were carried out at the same time. On the left is the picture of the KTV back alley. At around 12 noon that day, Li Tian, ​​​​the deceased, looked around, as if waiting for someone. Suddenly, a man wearing a hat and a mask appeared on the surveillance screen at the street entrance on the right. Into the back alley.

After Li Tian waited for the person to arrive, he argued with the other party, but the person did not intend to communicate with Li Tian, ​​so he quickly took out a piece of cloth from his pocket and covered Li Tian's mouth and nose, Li Tian struggled for a while and died After losing consciousness, he immediately took out a saw. The scene was extremely bloody, and the faces of the people in the meeting room were ugly.

Lin Huaiyue lowered her head, already beginning to regret agreeing to Yu Su to join the task force.Suddenly a document was placed in front of him, and Lin Huaiyue looked at Yu Su suspiciously, only to hear the other party say: "This is the basic information of the four deceased, and the written records of the murder scene, you can take a look at it some time, and give me a copy of the criminal record." Mental portrait."

"En." Lin Huaiyue responded, surprised by Yu Su's understanding, and quickly put into thinking.

The process of committing the crime was not short, and it can be seen that the murderer was still in a state of tension. Gu Li pushed back the time for a while, and the murderer waited until the sawed-off legs stopped bleeding, and put them into a suitcase full of stumps. left the scene.

Yu Su thought for a while, and then said to Gu Li: "Call out the video captured by the surveillance at the guard."

Gu Li compared the surveillance footage at the guard's office with the surveillance footage of the street intersection in the fourth case. The murderer had changed into the courier's clothes, but it was still the same person from his hat, mask, and exposed eyes.

Afterwards, Gu Li played another surveillance video. The murderer returned to the crime scene at ten o'clock in the evening, observed the deceased for a while, searched his body, and finally took away the deceased's mobile phone.

Holding an infrared pen in his hand, Yu Su pointed to the mobile phone taken away by the murderer on the screen, "The murderer should have gotten in touch with the deceased through a phone call, and pretended to buy it in order to let the deceased show up."

He has also been in the anti-narcotics team. It is not that he has not imagined this kind of fishing behavior, but drug dealers who are a bit vigilant will not take this kind of fishing. He spent a lot of effort to gain the trust of those people.

Obviously, this Li Tian wanted to make quick money by retailing drugs.

So Yu Su looked at Qi Yi and Gu Li, "Old Qi, you and Gu Li are in charge of investigating Li Tian's relationship to see if he is short of money recently."

Qi Yi immediately understood what Yu Su meant, nodded and said, "Okay, I'll send someone out to ask after the meeting."

Gu Li also nodded in agreement.

Yu Su nodded, and mentioned what he and Lin Huaiyue found in the morning, "Consultant Lin and I agree that the time for the murderer to enter the corpse dumping site should be earlier than the time when the warehouse opened last time, which is the last inspection of the inventory of each department of the hotel that afternoon. The logistics personnel who were concerned before entering and exiting the warehouse should be the time when the murderer left the scene."

According to this clue, Yu Su asked Gu Li to check the surveillance on the way back. When the logistics staff found out that there was an accident in the warehouse and the guests left the hotel in a hurry, there was an adult male with a height of about 1.7 meters [-] in the crowd, and there were no children around him. A man holding a hydrogen balloon.

"We have found a way for the murderer to leave the scene, but how did the murderer enter the warehouse? That is the question we will solve next." Yu Su said, looking at Gu Li.

Gu Li called out the monitoring of the warehouse inspection that afternoon, and the screen showed that only staff wearing hotel uniforms entered and exited the warehouse during this time period, and there were no suspicious staff.

"Wait." Lin Huaiyue stared at the monitor, "Please step back ten seconds."

After Gu Li followed suit, Lin Huaiyue asked again, "Back off again."

Back and forth several times, other people were tired of just watching this clip, and they didn't see any tricks, but Lin Huaiyue kept watching it repeatedly.

"stop!"

Lin Huaiyue suddenly made a sound, which attracted everyone's attention. He took the infrared pen from Yu Su's body, pointed to a person on the screen and said, "This is it, zoom in on this person."
