The more time passes in the case, the lower the chances of finding a new lead. If Murderer X had started committing the crime in 2005, 11 years have passed now, and the possibility that Gu Song and they could find a breakthrough point from it is almost zero.

With so many cases, let alone finding loopholes that were overlooked back then, it takes a long time just to re-read the mountains of written materials.

For a whole day, Gu Song and Zhong Xin spent their time on these headache-inducing documents. The facts of the case were clear, but no matter how they looked at it, they couldn't find any information that could help the case at hand.

Judging from the available information, Tiger and Bobcat, as a mature and experienced criminal gang, have always maintained a very tacit cooperation in a series of burglary and murder cases. From intelligence collection, to stepping on the scene, to committing crimes and selling stolen goods, they have shown their strengths and done their best, and they have long formed a set of unique crime models.

Combined with the analysis of the personalities and life experiences of the two people, Tiger is a rough and heroic man, who is resolute and resolute, has a criminal record of robbery with a knife, and should have undertaken most of the dirty work in all cases. The lynx is cunning and fickle, and he is well connected, and he must have done the work of gathering intelligence and selling stolen goods.

So, if there is a third member of the gang, the so-called murderer X, what kind of position will he be in the gang? What part of the work is he responsible for?

Through an arson case in the spring of 2011, Qiao Sheng deduced the existence of murderer X. Looking back now, Gu Song basically agreed with Qiao Sheng's judgment back then.

However, in the past investigation, the police did not find any identity information of this mysterious accomplice. In other words, they have not been able to prove that the murderers of tigers and lynxes, arson, and stolen goods must have been their accomplices.

The police deduced that Killer X should have had a criminal record, was probably between 30 and 50 years old, had a common intersection with a tiger or a bobcat, and may have served a sentence in the same prison district. This man is scheming, vicious, level-headed, and has a high IQ. However, the police searched for information from many sources and did not find the existence of qualified people.

If the murderer X really exists, and the police spend so much effort to find out the information of this person, but still find nothing, is there such a possibility: that is, there is a problem with the direction of their investigation back then?

They have been looking for someone who meets the above conditions around the tiger and the bobcat, but if that person does not meet the conditions listed by the police at all, they will not be able to find a person whose identity information does not match no matter how long they send out more police force.

Thinking of this, Gu Song's heart suddenly had a very familiar feeling: the identity information did not match, resulting in the wrong direction of the police's investigation, which was similar to several recent cases.

The murderer used Wei Chiliang's identity to commit the crime, completely diverting the focus of the police's investigation from himself. In this way, he can walk the streets openly without being detected by the police, using the transfer to achieve another form of stealth. No wonder Qiao Sheng has always compared this person to a ghost.

In fact, it's not that no one has ever seen him, it's that people can't identify him even if they do.

At the end of the day's work, Gu Song and Zhong Xin returned home dizzy. As soon as they entered the door, Jack, who had been left out for a day, rushed towards the two of them.

"I'm sorry." Gu Song touched Jack's head and said apologetically, "I'm too busy today to spend time with you." However, all I do now is to help you find the murderer of your master, you should be able to forgive me, right? ”

"Wang! Woof! Jack looked at him with big watery eyes, wagged his tail and barked at him twice, as if he understood. Gu Song continued: "Jack, how good it would be if you could speak, tell us who the murderer is directly, and save us from being tired and tired and not finding the slightest clue." ”

"Alright, don't think about the ones you don't need." Zhong Xin changed his slippers and walked into the living room, looked around, sniffed carefully with his nose, confirmed that Jack did not defecate in his house, and then said to Gu Song, "Hurry up and take it downstairs to solve its physiological needs, I think it is suffocated this day." ”

"Aren't you going with me?" Gu Song picked up the dog leash from the locker at the door and tied it around Jack's neck. Zhong Xin waved his hand at him tiredly and said, "I won't go." Just walking a dog in the neighborhood, you won't come up with any new tricks for me, will you? ”

"Of course not." Gu Song replied with a smile. "I see that you're really getting more and more at ease with me now."

"Trust each other to be a better partner. Go ahead, just be back in twenty minutes. ”

At ten o'clock in the evening, there were basically no people in the community coming out for activities. Gu Song led Jack to wander around the community, and the cold wind blew along the way, and the dizziness gradually eased a little.

Walking to an open lawn, Gu Song untied the dog leash and let Jack go to the grass to play, while he sat on a bench under the street lamp, fiddling with his mobile phone while enjoying the peace and tranquility of the night.

As soon as he opened WeChat, he saw Qi Ruonan posting all kinds of cute and silly photos of her Yashen in the circle of friends. In just a few minutes, those single young men in the police station rushed to like and leave messages for Ruonan, and took the opportunity to talk to her. Gu Song looked funny, and said that girls are popular in the criminal police team.

Idle and bored, Gu Song clicked on all the photos sent by Qi Ruonan and found that the husky was really a naturally stupid and cute animal, whether it was a serious expression or a funny expression, people couldn't help but laugh when they saw it.

On a whim, Gu Song took out a photo of Jack selling cuteness from his mobile phone and sent it to Ruonan.

In less than a minute, the other party replied with a message: Jack is so cute. If it weren't for the bullying of my family's Erha, I would be reluctant to send it away.

Gu Song replied with a comforting expression and said: It's okay, if you want it, you can come to my house to see it at any time.

Qi Ruonan sent a row of smiling faces and hugging expressions, and replied: Okay, I'll go and play with it when I have time.

The two of them chatted in WeChat.

Ruonan: Senior brother, how did you have fun in the past two days of the Chinese New Year? Have you brought your girlfriend home to meet your parents?

Gu Song: Not yet, I want to take her back when the time is right. What about you? Have you continued to develop a relationship with Fan Cong?

Ruonan: I hate it, people are just talking and playing casually in the office, how can you take that sentence seriously!

Gu Song: Ruonan, I'm not joking with you, I really think it's quite appropriate for the two of you to be together. Haven't you always wanted to find a down-to-earth and reliable man, I assure you that Fan Cong is absolutely reliable.

Ruonan: I know, I've known him for more than a day or two. Okay, let's not talk about that. Brother, when are we going to start working? I'm completely at your disposal now.

Gu Song: Actually, Zhong Xin and I have been rummaging through the materials in the archives all day today. I'm dizzy now, sitting on a bench in the community blowing the cold wind, sobering my head.

Ruonan: What? You're already investigating? Why don't you call me?

Gu Song: I want you to rest at home for two more days. If you're not tired, you can start working tomorrow.

Ruonan: No problem, it's been a long time since I've been so enthusiastic about my work. By the way, did you find anything new in your search today?

Gu Song: Not yet. However, with today's investigation, I am more certain that several recent homicides in R City are related to burglaries from a few years ago. I firmly believe that it is the right choice to shift the investigative focus from Wei Chiliang to the murderer X.

Ruonan: Senior brother, I support you. Let's follow this path and investigate, and we will definitely gain something.

Gu Song: I hope we can arrest the murderer X as soon as possible.

Ruonan: It's best to arrest Wei Chiliang together.

Gu Song: Yes, catching both of them is the most perfect ending.

After chatting with Ruonan, Gu Song glanced at the time, and there was still a short time before Zhong Xin's twenty minutes. Jack clearly wasn't having enough fun, and didn't want to go home at all. Seeing it bouncing around on the grass, Gu Song couldn't help but smile wryly and shook his head, and continued to pass the time with his mobile phone.

After clicking on the screen, the mobile phone screen still stays on the interface of WeChat chat. He casually swiped the screen, and suddenly, an inconspicuous but somewhat glaring message appeared in front of his eyes:

"You've added the Sunny Doll as a friend, now you can start chatting."

This is the information displayed after adding friends on WeChat, and this person called "Sunny Day Doll" is Lu Anxu, a reckless boy that Gu Song met in the pet store before.

A few days ago, because of his own "involvement", Lu Anxu accidentally broke into the broken brick house and witnessed the scene of the corpse crushing case. Recalling the boy's frightened expression, and the way he almost collapsed at the scene of throwing up the corpse, Gu Song's heart suddenly felt very uncomfortable.

At that time, the two people were sitting on the steps of the alley chatting. Gu Song exchanged contact information with the boy, and promised the other party that he would do his best to help him get rid of the impact of the case.

However, after that day, Gu Song has been busy doing his own thing, completely leaving Lu Anxu's experience behind. Until now, he didn't know what happened to the other party. Thinking of this, he couldn't help but feel a little ashamed......
