My treatment has been going on for more than a year, but I really didn't find any help in recovering my memory, and I thought about going with the flow, and forgetting that it was not a big deal for a lifetime if I couldn't remember, and gradually I didn't go to the hospital often. Li Jing didn't say anything, but sometimes there was more anxiety in my eyes, I always felt that Li Jing was more anxious than me about recovering his memory, but it seems that I am not the only one who needs to recover my memory, Li Jing and I are now entrusted by Mr. Lu to go to Q City to help a man who fainted at the crime scene, he woke up in the hospital and didn't remember what had happened at all, the lie detector confirmed that his amnesia was true, but in order to find out what happened at that time, to help solve the case, The police in Q City would like to ask Mr. Lu, who has cooperated before, to help. Mr. Lu was about to leave for the UK to attend the seminar, so he had to entrust us to help him handle it on his behalf.

Why are you obsessed with recovering the memory of this man, I asked Li Jing before leaving. Li Jing gave me a thick stack of materials on the high-speed train. I looked through the information, and it turned out to be a serial murder case, and the place where the man fainted was now confirmed to be related to the previous serial murders. The man's fingerprints and shoe prints were collected at the crime scene, although it is not certain that the man is the murderer, after all, the police did not collect any fingerprints or other DNA traces from the scene in the previous related cases, so it is difficult to judge whether this man is the murderer of a series of homicides. In addition, after this case, the case of the same criminal method occurred in another city, so it is even more difficult to judge the true identity of this man, this man can't even remember his name, after the official release of the man's news, although there are well-wishers who provide various clues, but after verification, they have nothing to do with this man, who is he? What does he have to do with the case?

Going back to the case, the case began last autumn and lasted until the early autumn of this year, because the city where the crime occurred was different, and the police did not link them together at first. It was only considered an independent case investigation, until the end of last year, when sorting out the files that had not been closed, one of the several police officers involved in the retrial of the case was a colleague who had been newly transferred from another city, and suddenly discovered that another case in Q City was very similar to the case he had tried before. The modus operandi of the 2,000 cases is 80% similar, and both cases occurred in cities along the TS Expressway, and the characteristics of the abandoned bodies were almost the same. According to this speculation, the police officer applied for access to the files of the cities around the TS Expressway for nearly a year. His actions and speculations also attracted the attention of the higher-ups, and after compiling all the files, they found that similar cases had occurred in a total of 8 cases in 7 cities, including two in Q City, and the only known person in the second case was the amnesiac man.

After the serial murders were confirmed, the police in seven cities brought the cases together, and all the forensic reports came with them, and the police officer from Q City was assigned to set up a task force to solve the TS highway serial murder case and became the team leader. According to the forensic report, the suspects in all cases used knives to commit the crime, according to preliminary judgment. The knife used in the crime was a 20-centimeter switchblade, and the murderer knew more about the human body structure, and did not find too many wounds on the corpse, and did not find the body with more than 3 fatal wounds. The victims received physical injuries in different ways prior to the killing, and according to the forensic judgment, the victims had been beaten by the suspect for two to three days prior to the killing. The body was not dehydrated, indicating that the victim had a steady source of food during the days of the suspect's captivity. Undigested food debris was found in the stomach, suggesting that the suspect had provided the men with enough food even before they were killed. Tong guò for the examination of undigested matter in the stomach. No drug components such as ecstasy were detected, but the victim did not show much signs of struggle before dying. The other, and most important, point is that the suspects have flagged these. This is also the most important basis for the officer to finally connect these cases - the uniform marking of the entity by the suspect.

A mark is a mark of the offender that anything other than the substance necessary for the crime will be used by the person involved in the investigation to identify whether the offender has engaged in the same criminal activity elsewhere. In serial murders in particular, the perpetrator repeatedly performs certain ritualistic acts, such as taking or leaving something behind from the victim, most notably the Rostow Butcher in the former Soviet Union, also known as the Forest Killer. The killings spanned all of Russia, and by the time they were finally investigated, he himself admitted to killing at least 53 people. After the killing, he removed the victim's eyes for fear of a lifeless void in them.

The marks left by the perpetrator at the crime scene are often used by investigators to study the unique cognitive processes of the offender, and in some cases are even more effective than the criminal's modus operandi to help investigators find the perpetrator and solve the crime. In the TS Highway serial murder case, the criminal killer also left a unique mark. After killing the victims, the suspect left a five-pointed star on the back of each victim's left hand. Although the investigators who had just started to deal with the case also made this an element of the key investigation, because the cases were not linked at the time, the results of the separate investigation did not break through because of the mark left by the murderer.

Another reason why these cases are not linked is that the victims of the cases do not have any common characteristics among themselves, the victims are male and female, and the appearance of the victims is different, and the investigation of the cases together is still not immediately possible to determine the special preferences of the suspect for the victim and successfully profile the suspect. On the other hand, combined with the joint investigation of the police in many places, Wutagram still has no clues available to solve the case with the task force, and at this time, an old leader of the Q City Police Department asked the police officer in charge of the task force to find out if it would help. Mr. Lu once helped Q City solve a difficult case during his seclusion in Q City, which left a deep impact on the old leaders of Peking Opera, so when the case was almost painful, he proposed such a proposal for the leader of the task force. And that's why we're now taking the high-speed rail to Q City.

We discussed the initial profile of the suspect on the train, and we ruled out the possibility that the female killer would have committed the crime alone. There are two or three that make us rule out the possibility that the female killer committed the crime alone, and first, because the medical examiner did not find the drug in the victim's stomach during the autopsy, because there are not only petite women among the victims. There are also tall men, and women subdue men unless they have an absolute body advantage or have a high level of combat experience. Under normal circumstances, it is impossible to subdue a man lightly, let alone according to the law that the victim has been detected before the murder with good physical features, no signs of binding of hands and feet, if the murderer is a single woman. It is indeed difficult to beat and kill a man when the victim is not in good health. Therefore, female murderers are limited by their body size when committing crimes, and usually use ****** Deng Duwu to kill victims, but no ****** or other toxic residues have been detected in practice.

Second, female serial killers are more likely to kill people they know, with a previous survey showing that only one-third of female killers would kill strangers, and two-thirds would kill people they knew. Most of the victims of female serial killers are husbands, ex-husbands, or suitors, and if the suspect is a female criminal who committed the crime alone, there should be a connection between the victims. However, prima facie, the eight victims did not know each other, and even according to the available information, there was no overlap in all the experiences of the victims (consumption, schooling and medical treatment). Assuming that there is no overlap between all the victims, it is unlikely that they will be connected to each other and commit something that would make the offender kill them because of their hatred, so based on the fact that the victim is a stranger, we also sent the possibility of a female offender committing the crime alone. But for the victims, Li Jing asked Shi Hao to continue to help us investigate in depth to make sure that there was indeed no connection between the victims.

Third. That is, after the victims were kidnapped, the families of these victims did not receive a ransom call from the chest gloves, indicating that the murderer did not kill for money, and the main purpose of the female serial killers to commit multiple murders was for money. For example, insurance indemnity, estate distribution, trusts and real estate, but in the investigation of the case, the heirs who induced the birth of the victim8 were also irrelevant. Combining the above three points, let us be more sure that the murderer is not a single female criminal.

However, we have not ruled out the possibility of female offenders being involved in the crime, and previous surveys have also shown that about half of female serial killers have male companions. Their companions may be from a cult like him, or they may be married to some male serial killer. The notorious serial killer Charlie Manson and the women of the Manson family, the extremist organization he founded, chase

We understand the officer's urgency to recover the memories of the amnesiac at the crime scene. But in addition to this clue, Li Jing firmly believes that other clues can be found from these cases. While we were still discussing, we arrived at the station in Q City, and the police station was only half a stop away from the station, and Li Jing and I walked to it. At the door of the police station, we saw Officer Liu waiting for us (the leader of the task force mentioned earlier), although Mr. Lu had mentioned to Officer Liu that we were relatively young before we set off, but when he saw our real person, Officer Liu's eyes were still wide, but he immediately recovered his previous calm and took us to his office. Officer Liu is more than 1.8 meters tall, combing Italian lean short hair, wearing a smooth gray-blue shirt and light gray trousers with good workmanship and good texture, wearing a thick dark gray belt, his leather shoes are polished very brightly, and his trousers are also carefully cared for.

"It's going to be watery." Li Jing poked me next to me.

"Nasty." I gave him an angry look.

Push the door into the office, this is a six-person room, in addition to Officer Liu, there are 4 other task force personnel, and the rest of the position is to receive people who come to provide clues, but many people have come back and forth, and still no valuable clues have been obtained. Because we already had a general understanding of the case in the car before, the task force did not attach too much information about the case for us, but asked us for our opinions. We told the investigators of the task force our preliminary profile of the suspect, and we were affirmed. But as we inferred before, the members of the button arresting team did not think that the murderer would be a single woman, but it cannot be ruled out that there were female criminals among the suspects.

When we asked the reason, Officer Liu told us that when they searched for information, they found that three long hairs belonging to the same woman were found on the male amnesiac, although the owner of the hair was not found, but it was certain that it came from a woman who came into contact with a man, although it is also possible that it was just inadvertently glued to his body, but the probability of a person sticking three hairs from the same woman is indeed relatively low, so it is temporarily inferred that this woman and the frustrated man know each other. And the hair DNA sample found on the frustrated person is not the same as the previous victim, so it is difficult to judge whether this man is really directly related to the case. However, judging from the traces of blood on the amnesiac when she was found, she fell at the crime scene after the crime, because there was no splash of blood on her clothes, so there is no evidence to directly point out that he is the suspect.

On the other hand, although the task force has released information about amnesiac people, and there are families who have recently disappeared in their homes who want to confirm the identity of the frustrated people, the DNA samples of all these applicants do not match the three hairs. It is said that if a missing person is missing in the family for more than 24 hours, the case can be reported, and under the repeated publicity of the police, if it is completely irrelevant to the case, someone will always come to claim it, but none of the friends or family members of the amnesiac have contacted the police, so the police still have not completely ruled out the suspicion that the amnesiac may be the murderer.

In this dilemma, Li Jingti wanted to visit the amnesiac. On the way to the hospital, Officer Liu said that amnesiac people were very repulsive to the hypnotherapy of the hospital's psychotherapists, as if they were deliberately avoiding all memories. It's not that he didn't imagine the possibility that the frustrated person was really the murderer, but the subsequent cases in other cities also made him think that it might be his judgment error.

"If it was a group crime, it was likely that he was a pawn that was sacrificed, so after we visited the amnesiac for a while, we will reorganize the case and write about the type of suspect according to the content of this conversation. Now that some hair samples have been found, it shows that he himself has companions, but his classmates have been slow to come to him, or even come to report the crime, and it is not related to the serial murders we investigated, I think the identity of this amnesiac is not necessarily innocent. ”

Officer Liu nodded, and a handle was transferred to the hospital on the side of the road. (To be continued.) )
