After the breakup, Song Qianqian never contacted Wei Chiliang again.

At the end of 2013, when she learned from the news that the murderer of the six serial corpse mutilation murders in R City was Wei Chiliang, her first reaction was shock. Then she realized that it was not without warning that Wei Chiliang did such a thing.

She was glad that she had left the demon in time and had not become a victim of the seventh. But at the same time, she also had such a question in her heart: If she hadn't left the villa and didn't treat Wei Chiliang as a madman, but a patient, if she could have been braver, had more courage to help him, and worked hard to bring him back on the right track in life, would these tragedies still happen?

After listening to Song Qianqian's narration, Qi Ruonan was silent for a long time before speaking: "From the perspective of ordinary people, you haven't done anything wrong. Wei Chiliang's self-destruction laid the foundation for danger as early as his teenage years. Maybe your persistence can save him, maybe it won't. You didn't risk your life, and that's a more sensible decision. No matter what happened afterwards, you weren't hurt by him, and you were alive and sound, which is already a good result, isn't it? ”

Song Qianqian nodded slowly, "I just hope that you can catch that dangerous guy soon, and don't let him hurt more people." ”

"Don't worry, we'll definitely work hard." Qi Ruonan replied with conviction.

After seeing Song Qianqian walk out of the teahouse, Qi Ruonan moved a position, sat opposite Fan Cong, looked at him curiously and asked, "Brother Cong, why didn't you speak today?" I was there just a moment ago. ”

Fan Cong picked up the cup, took a sip of the jasmine tea that had been cold, and said with a smile: "I see that you two girls have a good conversation, so I don't want to follow it." ”

"I didn't expect things to go so smoothly today, and we got to the point at once. Originally, I wanted to ask her if Wei Chiliang liked to have pets and whether she had any special feelings for dogs, but before she asked, she said it all herself. ”

"Yes, in this way, we can be more sure that the murderer of the burglary is not Wei Chiliang. Judging from Wei Chiliang's character, he has no reason to protect the victim's dogs, even if he doesn't kill them and break them into pieces, he won't prepare enough food and water for them, so that they can safely wait for the police to rescue. ”

"This is the characteristic of Murderer X. The person who has a special affection for the dog is the murderer X, not Wei Chiliang. Qi Ruonan said and stood up, "Let's go, let's go back to the police station and help the senior brother and them continue to check the information on those burglaries back then." ”

Half an hour later, the four members of the "Special Investigation Team" met in the office of the task force on the third floor of the Interpol team. Except for a few of them, the others were all headlong in the task of capturing Wei Chiliang. The leader above has not issued a new order, and it is estimated that Qiao Sheng failed to convince them to shift the investigation to the murderer X.

Although Gu Song felt that what those people were doing now was a waste of time, he was not qualified to persuade others to act according to his ideas. Fortunately, Qiao Sheng was on their side. The reason why they were able to get so many files and materials in a short period of time was because of Qiao Sheng's credit.

Several people gathered around the conference table, with a mountain of papers in front of them. Gu Song and Zhong Xin have already read most of this information. In order to find new clues, they decided to go through all the documents again.

According to the era of the burglary, several people worked together. Gu Song and Zhong Xin were responsible for looking at the data from 2005 to 2008, and Qi Ruonan and Fan Cong were responsible for the data from 2008 to 2011.

According to incomplete statistics, the criminal gang committed six murders in six years, involving eight lives.

The first case occurred at around 10 p.m. on 20 July 2005 in Nanchang City, Jiangxi Province. The deceased was a 25-year-old single girl who lived alone, and she was usually vigilant and would not easily open the door to a strange man. The tiger is big and thick, and the bobcat looks like a thief, and it's hard to imagine that the victim would take the initiative to let these two guys into the house on a stormy night.

The second to fifth cases occurred in four cities: Changsha in Hunan, Jingzhou in Hubei, Guiyang in Guizhou, and Shantou in Guangdong. The police grouped together the unsolved burglary and homicide cases based on a highly similar pattern of crimes, believing that these cases were also committed by a criminal gang composed of tigers and lynx.

The last case occurred at around 3 p.m. on April 12, 2011, in R City, Sichuan Province. The deceased was a 65-year-old woman. Because there is a priceless antique porcelain hidden in the house, and she is afraid of attracting thieves at home, the old woman's sense of self-protection is even stronger, and she will not open the door to someone she doesn't know when she is at home. Even the wife of the deceased couldn't figure out how the murderer tricked the old man into opening the door.

After reading the relevant information of the last case, Fan Cong raised his head, looked at the other people, and said thoughtfully: "From the current information, it is likely that one of the tasks undertaken by this murderer X is to deceive the door and break into the house. ”

Gu Song rubbed his temples and said approvingly, "I think so too." And he should not be very old, very approachable in appearance, and thin in stature, so that the victim can easily take off his guard. ”

"Senior brother." Qi Ruonan suddenly interjected, "You said that the reason why the police couldn't find this murderer X back then was because their investigation went in the wrong direction. Because Killer X did not meet the criteria they had analyzed, they were unable to find out any information about this person. You say......" she paused and asked suspiciously, "could Murderer X be a woman?" ”

"What? Female? Fan Cong showed a surprised expression, not believing that a weak woman could create so many heart-wrenching homicides in R City, and make the R City police around.

Qi Ruonan continued: "Some criminal gangs are husband and wife files. If Killer X is a lover of a tiger or a bobcat, it makes sense that she has been following them all the way around the country. And as a weak woman, her success rate of deceiving the door will naturally be much higher than that of men. ”

"According to what you say, let the child cheat the door, the success rate is even higher."

"What? Child? "This time it's Qi Ruonan's turn to question." It's possible to let children cheat on the door, but don't forget, Killer X killed both the tiger and the lynx in the spring of 2011. He swept away all the stolen goods, erased all traces of a threat to himself, and finally set fire to the corpses of tigers and lynxes. How could a child do such a horrible thing? What's more, Killer X has a lot of criminal experience, do you think a little kid can do this alone? ”

"This ......" Fan Cong was speechless for a while, so he asked Qi Ruonan in turn, "Then do you think a weak woman can do this?" ”

"Eh, what is this......" Qi Ruonan was also speechless when asked. The two looked at each other for a while, and they both looked at Gu Song in unison. The latter was stunned for a moment, and urged them: "Quick, take a closer look at the investigation records of that year, and see if there is any mention of children in the information of the mass visits." ”

"Huh? Why small children? Qi Ruonan and Fan Cong asked in unison.

Gu Song explained to them while flipping through the information: "Because through the previous investigation information, we learned that the murderer X hid himself too deeply, like a ghost that does not exist in this world. If Killer X is the lover of a tiger or a bobcat, it is not easy for an adult woman to completely hide traces of her existence. But it's not the same with children. If the tiger and the lynx controlled the child and deliberately hid him, it is relatively understandable that the police did not find any information. The children of that year are now grown up and are fully capable of committing these recent tragic murder cases. ”

"But Senior Brother......" Qi Ruonan still didn't quite believe it, "Do you really think that children have the ability to kill the two fierce and cunning adults, the tiger and the lynx, and set fire to their corpses?" ”

"There are exceptions to everything, and maybe we are facing such an unexpected 'criminal genius'."

Hearing this, the office suddenly became quiet. Several people stopped talking, silently lowered their heads and began to look through the information in their hands.

After more than ten minutes, Fan Cong found a piece of information that had been ignored before. "At around 2 p.m. on April 12, 2011, just before the murder of an elderly woman with antique porcelain in her home, Ms. Sun, who lived in the same residential building as the victim, was questioned by the police about a junior high school student."

"Did the woman who was drying clothes on the balcony say that?" Gu Song put down the document in his hand and raised his head to ask, as if he still had a little impression of this information in his mind.

Fan Cong nodded and said, "According to Ms. Sun's reaction, she didn't notice anything special at that time, nor did she notice any suspicious people in the community. Because there are often people walking around the community, she can't tell which is the good and which is the bad. Before she dried her clothes, she casually glanced downstairs a few times, and she saw nothing more than two young women holding their children outside in the sun, and in addition to that, a junior high school student wearing a school uniform and carrying a schoolbag. ”

"No, you mean ......" Qi Ruonan's eyes widened in surprise, feeling that he was becoming more and more unable to accept their speculation. She could see that Gu Song was very interested in this information. She knew that the reason why people were ignoring this message was because no one had ever thought that the person who killed the tiger and the lynx and destroyed the crime scene like that would be a child.

"A junior high school student in 2011 is about 13 or 4 years old...... Gu Song muttered to himself, "In 2005, when the criminal gang committed the first case, he was 7 or 8 years old. It's 2016, and his age is about 18 or 9 years old, and he should look like a college student......" Suddenly, Gu Song remembered something that happened this morning, and a layer of cold sweat couldn't help but break out on his back.

"Damn, won't you......" He clenched his fists, looked at Zhong Xin in horror and said, "It seems that we still have to go to the 'Jiayuan' Pet Life Center again, and I have to confirm with the boss there for a situation." ”
