Zuo Huanqiu is still very interesting, when he introduced Zhang Xizhong to Duan Yu, he deliberately praised Zhang Xizhong, saying that he was the first master of the Lishan City Public Security Bureau to solve cases, specializing in solving difficult and strange cases, and he was also commended by the Ministry of Public Security, and was awarded two collective third-class merits and three individual third-class merits.

Giving Zuo Huanqiu such a thing touched Duan Yu's heart, that is, when he first arrived in Lishan City, Ma Qicheng, deputy director of Gaokai District, died in a traffic accident, Duan Yu always felt that Ma Qicheng's death was a little strange, but there was no evidence, and second, he had just come to Lishan at that time, he had no foundation, and there was no trustworthy person in the public security department, so he couldn't investigate it if he wanted to, but this matter has been like a thorn in his heart.

And with his intuition, Ma Qicheng's death should be inseparable from the executive deputy mayor Zheng Jishi, Zheng Jishi is Wu Guoguang's loyal iron, at present, Duan Yu and Wu Guoguang have been on the same footing, it is difficult to maintain a group of harmony, and Duan Yu also knows that it is impossible to bring down Wu Guoguang, the secretary of the municipal party committee, at once, after all, the involvement is too great, but Duan Yu also learned the lesson of Wu Guoguang's sudden move last time, and reversed the slight advantage he had accumulated in the Standing Committee at once, knowing that if he fights a snake and does not die, he will be bitten by a snake, so he naturally wants to take advantage of the situation, Wu Guoguang can't be defeated for a while, so cut off his wings first, and Zheng Jishi is undoubtedly Duan Yu's first choice!

Now that Duan Yu has gained a firm foothold in Lishan City, and the public security has a trustworthy person, he mentioned it to Zuo Huanqiu, and brought up this matter that had been hidden in his heart for a long time, and immediately handed over the task of investigating this case to Zhang Xizhong, who is known as the first master of the investigation of the Lishan Public Security Bureau, and specially told Zhang Xizhong that the investigation must be carried out in secret, not to startle the snake, and to report directly to him if he finds something.

Zhang Xizhong was overjoyed to be able to get the respect of Duan Yu, the big mayor, not to mention that he was originally jealous and hateful, and when he heard that there was a strange case, he was itching all over his body, and he immediately received the task and returned to the team, as if he had been beaten with chicken blood, and he was full of energy to find out about this mysterious case.

However, when Zhang Xizhong read the relevant case files, he scratched his head for a while, because this case is basically a headless case, and after so much time, even if there are any clues left, it is impossible to find them.

The only clue is that Liu Liuliang, the driver who killed Ma Qicheng and later surrendered voluntarily, but this Liu Liang was exempted from criminal responsibility because he voluntarily surrendered and the compensation was quickly paid, so he was finally exempted from criminal responsibility, and was released after fifteen days of detention, and that Liu Liang went to other places shortly after coming out of the detention center and has not returned for a long time.

From this point of view, Zhang Xizhong also felt very suspicious, if there was no ghost in his heart, why did this Liu Liang go to other places shortly after he came out of the detention center? However, suspicious is suspicious, and since Liu Liang has no news, then the clue is equivalent to being broken.

If it is an ordinary person, he is afraid that he will be a little discouraged when he finds out here, but Zhang Xizhong is obviously not an ordinary person, since this Liu Liang is suspicious, he focused on this Liu Liang, and made a detailed investigation of this Liu Liang's family background and social relations.

This check, there are more suspicious points, this Liu Liang is a social unemployed person, he has been in prison several times for fighting and stealing property, and he does not repent after coming out, he is idle all day long, he likes to go to the bar to hook up with his sister, and the family conditions are also very average, his parents are ordinary workers, and his family background has long been lost by Liu Liang, a loser, so the question is, how did Liu Liang compensate Ma Qicheng's family for the traffic accident compensation come from, it is a huge sum of hundreds of thousands! Zhang Xizhong concluded that there must be a cat in it!

But no matter how many suspicions there are, it is useless to find Liu Liang himself, but Zhang Xizhong is not discouraged, as he himself said, half of the case is handled by luck, half by patience, he patiently investigated Liu Liang's social relations, arranged for plainclothes police officers to squat near Liu Liang's possible contacts, and also inquired about Liu Liang's whereabouts through some secret informants at hand.

The hard work paid off, and soon news came from a secret informant that Liu Liang had returned to Lishan City! However, this guy was very cunning and had no contact with his family and former fox friends at all, so the Public Security Bureau could not grasp his whereabouts!

Now Zhang Xizhong can almost conclude that there is something wrong with this Liu Liang! If there is no problem, why don't he even contact his family members and former fox friends and dog friends? At this time, Zhang Xizhong's old way of handling cases was revealed; according to the opinions of several impulsive young criminal policemen in the serious crime team, he was ready to immediately bring Liu Liang back for interrogation, but Zhang Xizhong vetoed it, because if Liu Liang was arrested at this time, he could completely push it away, but on the contrary, he would be startled.

So Zhang Xizhong decided not to startle the snake first, and only arranged a few trustworthy and capable plainclothes criminal policemen to secretly control Liu Liang's side, and soon the plainclothes criminal police who followed Liu Liang fed back the information, this Liu Liang is indeed suspicious, and he is very generous, almost every night he has to go to the bar to club, ordering thousands of yuan a bottle of foreign wine, and this kid is very romantic, almost every night he has to hook up with a coquettish bar girl to open a room in the hotel, but he has never seen this kid go out to work or do any business, so where did the money he squandered come from？！

The more suspicious points, the more difficult it is to handle the case, because this Liu Liang is not only very cunning, but also seems to have a strong anti-reconnaissance ability, he stays in a hotel every day, and never stays in the same hotel for more than three nights, basically a shot to change places, and several times the plainclothes criminal police who followed him were almost discovered by him, so he didn't dare to follow too closely.

The case has reached an impasse again, this Liu Liang is so cunning, he has been tracking for so long and has not found any clues, he can't follow it so endlessly, but Zhang Xizhong believes that no matter how cunning the fox is, when the fox shows its tail, he asked the plainclothes criminal police who followed Liu Liang to register the places that Liu Liang has been to every day, whether they are suspicious or not, and then he marked all the places Liu Liang has been to on the electronic map of Lishan City and connected them into a line, so as to find out Liu Liang's activity rules!

In this way, a new suspicion was discovered, recently Liu Liang appeared near the Jade Garden in Lishan City for several days, and once drove a rented BMW into the Jade Garden, and this Jade Garden is a well-known high-end community in Lishan City, and the owners who live in it are either rich or expensive, what is Liu Liang, an unemployed vagrant, going to do there? !

However, it is precisely because this jade garden is a well-known high-end community in Lishan City, so the property management is also relatively strict, like Liu Liang drove a BMW to go in, like Liu Liang drove a BMW to go in, but the plainclothes criminal police who followed him drove a BYD with a civilian license plate, I wanted to follow in to see, but I was stopped by the security guards at the door, and tried left and right like a prisoner, so angry that those plainclothes criminal policemen wanted to scold like Andy Lau in "No Thieves in the World", "Does a good car have to be a good person?!" , but in order not to startle the snake, the plainclothes criminal policemen did not dare to reveal their identities to follow up, so they don't know what Liu Liang did after entering the Jade Community.

Relying on his keen intuition and experience in handling cases, Zhang Xizhong immediately concluded that there must be something wrong here! Since there was no new discovery in tracking Liu Liang, he started with the investigation of the Jade Community, and he personally led the team to the Jade Community, found the security captain of the Jade Community, revealed his identity to him, and then asked if anything unusual had happened in the community recently.

The security captain of the Jade Community began to be very arrogant, and even Zhang Xizhong, the leader of the serious crime team, didn't pay attention to it, and asked what he didn't know, and he didn't know anything, no wonder he lived in the Jade Community, and even the security captain was a little nose-up, and he didn't know who he was.

However, this is not difficult for Zhang Xizhong, who is not the leader of the serious crime team in vain, what kind of person has never seen him? After a few random taps, the security captain became honest and asked what he answered, and this question was asked again! Recently, there have been two theft cases in the community in a row, with an interval of only half a month, and the theft was actually made by the same owner! What's even more strange is that the owner of this household began to scold the property and the security guard, saying that he wanted to fire their squid, but later when the security captain said that he wanted to report the crime, the owner suddenly said that there was no theft and did not report the crime!

However, the security captain didn't take this matter too seriously, now the rich people have a lot of strange problems, and there are all kinds of strange things, since the owner himself does not pursue it, it is naturally better to have more than one thing, not to mention that the boss of the property company also called and said that this matter is not allowed to be mentioned to the outside world, so it was not reported to the public security organs.

Zhang Xizhong was overjoyed when he heard it, and knew that the key to the case was that he was afraid that it would fall on this strange theft case! Immediately asked to access the information of the owner of the stolen household, the owner's registration information is a young woman in her twenties, according to the security captain, this young woman is very charming, driving a BMW, wearing an international brand, before there is a middle-aged man who often goes in and out of the young woman's home, but every time he comes, he sits in the car, and does not look at his face at all, and after the second theft, the young woman has moved out of the jade community, the middle-aged man has never been to the mansion again, and the mansion is now uninhabited!

The clue seems to be broken again, but Zhang Xizhong doesn't think so, he can almost conclude that this theft case must have nothing to do with Liu Liang, and immediately decisively ordered to arrest Liu Liang!

But at this time, there was another accident, because the Public Security Bureau's large-scale anti-pornography and anti-illegal operation began! Liu Liang didn't know if he was alarmed by this huge anti-pornography and anti-illegal action, and once again disappeared from the sight of the plainclothes criminal police who were following him!
