The captain of the criminal investigation team called Lao Chen and Xiao Zhang back with an emergency phone.

The two of them walked into the captain's office, and the room was greeted by thick smoke, and the cigarette butts in the ashtray were piled into small hills.

The captain asked, "Is there any progress?" The leader urges it! You two look at this. As he spoke, he handed over a notice of assistance investigation.

The investigation report was issued by the local police after the fingerprints of Kongyuan and Tongyun were found in Shanxi.

It turned out that after the local police discovered the disappearance of the Singaporean guest, they immediately launched an investigation; When checking the airport surveillance, it was found that the Singaporean guest was picked up by a man wearing a trench coat, sunglasses and a red hat, and after checking the license plate of the pick-up car, it was recognized as a stolen vehicle; After finding the abandoned car on the side of the road through video tracking all the way, there was no one in the car; No traces of a fight or blood were found on the car, and all fingerprints on the car were wiped clean; The police judged that the hijacker was premeditated, and it is not yet possible to tell whether the life of the Singaporean guest is in danger.

The local police in Shanxi immediately listed the case as a criminal case. Among the many video clues, the face of the person who picks up the car can be seen more clearly is the image when the car passes through the toll gate, through which it can be confirmed that the person wearing a red hat is the driver of the car; However, due to the fact that the man was wearing sunglasses and frequently turned his head to talk to the person in the back seat, he could not confirm his facial features. Later, through the slow-down image, it was found that when the driver paid the parking fee, he did not scan the code according to the current usual practice, but paid cash, and the money paid was new banknotes; So the police quickly found the banknote and found fingerprints on it; Through the comparison of fingerprints published on the intranet, it was found that the fingerprints on the banknotes were the same as the Tongyun and Kongyuan fingerprints that the Fujian police requested to investigate online; Since the original place of the Kongyuan case was in Fujian, the police in Fujian were immediately notified.

Xiao Zhang read the bulletin, and said as if he was surprised: "How can there be fingerprints on the banknotes?" ”

Lao Chen nodded and said, "I know this situation. During a visit to the village, someone said that Tongyun liked to collect new banknotes, and when the man helped the monastery count the incense money after a puja, Tongyun asked him to gather the new banknotes together. It can be shown from this that the incense money that Tongyun kept in the temple was taken away by the empty edge. ”

Xiao Zhang said a little proudly: "Look, I'm right, the empty fate is to kill for money." ”

As he was talking, the landline on the captain's desk rang, and he picked up the phone, which he arranged to call from someone who went to find Wu Yijin; said on the phone that Wu Yijin identified Kongyuan from the photo as the person who killed Liu Ermao.

The captain put down the phone and said, "This end is finalized, Wu Yijin recognized that the person who killed Liu Ermao was Kongyuan." Then he looked at Lao Chen with a trusting gaze: "Lao Chen, what do you think?" ”

Lao Chen didn't answer the captain, but asked Xiao Zhang directly: "If Kongyuan killed her master to make money, then why did she kill Liu Ermao for?" ”

Xiao Zhang shook his head and didn't speak.

Lao Chen analyzed: "I think to answer this question, we should look at the process of killing Liu Ermao in the air. From what we learned, the situation is like this, first Liu Ermao told the network administrator who sent the message that he wanted to find the empty edge, and said that it was an urgent matter, probably because he was worried that the empty edge would ignore him, and then asked the network manager to tell him, saying that it was about 'Yanqiu'. What Liu Ermao wants to do with Kongyuan is a money and material transaction, Liu Ermao gives things, and Kongyuan gives money; The empty edge came to the agreed location, but not to trade immediately, but to arrive at the location in advance to step on the spot; In the process of bartering money and goods, Kongyuan led Liu Ermao into a secluded place and killed him and snatched the object. ”

Xiao Zhang took out the cigarette case while thinking, subconsciously just took out a cigarette but stopped, took out two more cigarettes from the cigarette case, and handed them to the two; Lao Chen waved his hand and reminded him: "This is indoors!" ”

The captain said: "Smoke, smoke, this is my exclusive territory, it has long been smoky, come, I'll turn on the exhaust fan." ”

The three of them lit cigarettes, and Lao Chen continued: "The reason why she was ruthless in the void was not only that she felt blackmailed, but also that the object was important to her; Let's analyze it, when the empty edge doesn't see the object, you know that the importance of the object should be related to the network management saying that it is about 'Yanqiu', that is, Liu Ermao is right, and he pays attention to the 'Yanqiu' empty edge; Judging from the fact that she stepped on the point first, and then led Liu Ermao into a secluded place before attacking, killing Liu Ermao was premeditated, and she was ready to kill before she saw Liu Ermao, which shows that this 'Yanqiu' is very important to her. ”

Xiao Zhang seemed to feel that there were still doubts: "There is another point, will Kong Yuan not only kill people for the sake of grabbing things, but also worry that Liu Ermao will know about 'Yanqiu' and kill him?" ”

Lao Chen looked at him approvingly and said, "There is also this factor, but whether it is to seize the object or extinguish the mouth, it shows the importance of that object to the void edge. ”

Xiao Zhang said: "I used to think that if the 'Yanqiu' involved in that object was a woman, it would be because Kongyuan was 'stealing' and afraid of being exposed before killing people; ”

The captain frowned, smoking a cigarette without saying a word.

"I've thought about this question, and from the clues I have now, I can't determine that 'Yanqiu' is a woman, so I can't conclude with those two words." Lao Chen extinguished the cigarette butt and said, "But the looted thing involves 'Yanqiu', that's for sure." These two murders were committed by the same person in a short period of time, can there be an intrinsic connection? This determines the direction of the new cases that will occur next, and we need to first find the logical relationship between the two cases and analyze the question of who was killed first. ”

Xiao Zhang took out a small notebook and took notes seriously, and Lao Chen continued to analyze: "If Kongyuan kills the master first in order to rob money, and then kills Liu Ermao in order to snatch back the 'Yanqiu', it doesn't make sense, because he has already committed a crime, and he runs for his life first, how can he bother to grab items that have nothing to do with survival." And if you kill Liu Ermao first, then kill the master, and take the incense money as the travel expenses, in addition to escaping for your life, you will also have the idea of settling the grievances that have accumulated over the years since you have committed the crime. I think the probability of the second one is relatively high, so the next step is that she will use the travel fee to go to another place and continue to solve the unresolved grudges, so it will not be by chance that she appeared in the city in the north. ”

Xiao Zhang seemed to pick up Lao Zhang's train of thought and asked: "Judging from the current situation, that city is where Zong Zhenlei lives, so is it related to Zong Zhenlei to go to that city by air?" What is the relationship between Zong Zhenlei and the void? ”

The captain interjected and said: "It depends on whether Zong Zhenlei plays an important role in this case." ”

Lao Chen said for a while and felt that his mouth was dry, and he wanted to find water to drink, he glanced at the table, but he didn't find it, and when he heard the captain's words, he continued: "To clarify whether Zong Zhenlei's role is important, let's first take a look at what we know about Zong Zhenlei's behavior after coming to this county; Zong Zhenlei didn't stay in this county for a long time, basically walking from morning to night, and it was only eight or nine hours; He first went to the monastery in the small fishing village, stayed in it all morning, left the monastery at noon, returned to the hotel to look for something, then left the hotel, and left the county by train, never returning. We have to think about a few questions about Zong Zhenlei, is he related to the murder case? Is it to be regarded as a person who solves the problem of years of resentment? Is it an intermediary involved in other things related to the void? ”

Seeing that Lao Chen wanted to find water, Xiao Zhang glanced at the captain's table with his eyes, and found that there was a can of good Tieguanyin tea, and saw that the captain was listening attentively, so he put down the small notebook of the record and said, "I'll make tea for you." ”

The captain handed Lao Chen and Xiao Zhang a cigarette each.

Lao Chen lit a cigarette and said: "After Zong Zhenlei left the temple, Kongyuan created two cases, so I will focus on analyzing the three points related to Zong Zhenlei mentioned earlier. The first point is whether the case is relevant to him; At present, no connection has been found between him and the killing of Tongyun and Liu Ermao by the sky, but judging from the time of the crime, his arrival seems to be the beginning of the crime; the second point, the relationship between Zong Zhenlei and the void; He inquired with the owner of the small hotel before he found the temple in the small fishing village, which shows that he was not familiar with this place; After he entered the temple, there was no sign of dispute with the people inside, and no chat records with Zong Zhenlei were found in the Internet café computer used by Kongyuan, and the two people did not seem to have any intersection, but it was not possible to rule out the resentment caused by Kongyuan's other connections with him; The third point is the issue of intermediary; If the object he was looking for when he returned to the hotel was the object related to 'Yanqiu', was this object his, or was it passed on for someone else? If it is passed on by an intermediary for others, there is a question of whether this person has accumulated grievances with the void for many years. These need to be contacted by Zong Zhenlei before they can be conclusive. ”

Xiao Zhang was pouring tea into the fair cup next to the tea tray while looking at the record of the small book: "Earlier, you said that the empty edge 'since you have committed a crime, you have to settle the idea of resentment over the years', what does this mean?" ”

Lao Chen continued: "When I saw that on the test sheet, Tongyun's bed had both Tongyun and Kong's hair DNA, I was thinking about this question. Kongyuan told her little friend that she couldn't tell her gender, otherwise the two people in the temple would have to go alone, feeling that she was safeguarding the interests of her master Tongyun, judging from the age when she said this to her little friend, she should have been young at the time; But if after Kongyuan grows up, Tongyun still leaves Kongyuan in his bed, after all, the age difference between the two is more than sixty years, and it is hard to imagine that Kongyuan has always been willing. ”

Lao Chen pointed to the piece of paper in front of him that only he could understand and said: "Although Tongyun will instill some ideas into Kongyuan to balance her moral concepts, physiologically, Kongyuan may not always accept it; What's more, the empty fate will go online, and the input of foreign concepts will inevitably affect her understanding of the outlook on life, so once she has her own ideas and wishes, her master will force her to do what she is unwilling to do, and there will inevitably be resentment. ”

Xiao Zhang made the tea in an old-fashioned way, then filled the three kung fu tea cups, and made a gesture of invitation to the two.

Lao Chen nodded to him to express his gratitude, picked up a teacup and drank it, and said, "Good tea!" Fragrant! I'll go on. Once Kongyuan grabs the object related to 'Yanqiu', it will be roughly compared, is it important for her master or something related to 'Yanqiu'? From the current point of view, she chose 'Yanqiu', and her master may be the one who hinders her choice, when she makes a choice between two or the other, she will definitely abandon one side, and if the person who hinders her is the one she is ready to abandon, she will definitely kill the killer at all costs. When we visited the village, some people said that she was a cold-blooded 'ruthless' person, judging from the fact that she killed the master who raised her to adulthood, she was indeed cold-blooded enough, but at the same time, it also showed that the matter related to 'Yanqiu' was very important to her, so I think that 'Yanqiu' was the motive that made her create two murders in a short period of time. ”

The captain didn't seem to get out of the case, he was still sorting out the logical lines in his heart, he didn't speak, just silently stretched out his hand to the teacup.

Xiao Zhang obviously understood, and asked: "I have a question that has been wandering in my mind, since it is said that Kongyuan killed Tongyun, I heard the people in the village say that Kongyuan's martial arts are taught by Tongyun, and Kongyuan can't beat Tongyun, so how can Kongyuan subdue Tongyun and poison him?" ”

Lao Chen extinguished the cigarette butt and said, "You asked well, I also had questions about this question; Tongyun is a traditional Chinese medicine practitioner, often prescribing medicine to the villagers to treat diseases, and he is a person who practices martial arts, so it stands to reason that he can distinguish the smell of poison, so it is not easy to poison him, unless he ......"

Xiao Zhang replied: "Knock him out? ”

The captain picked up the teacup and leaned back, saying, "So easy? The master of martial arts feels that it is very, how can it be so easy to succeed. ”

Lao Chen continued his train of thought and said: "Unless you use ecstasy on him while he is not paying attention, stun him first, and then use poison on him; Kongyuan has followed Tongyun since he was a child, and it is not surprising that he will know the configuration of this medicine, but this is just a guess for me. ”

Xiao Zhang probably thought of the Zhang Xiecha report, and asked: "Kongyuan killed two people here with us, if it is related to the choice of 'Yanqiu', it can be said, but if you go to the northern city to kidnap Singaporean guests, this should have nothing to do with the choice of 'Yanqiu', right?" ”

Lao Chen nodded and said, "You get to the point." Kongyuan chose 'Yanqiu' here, and went over there to kidnap Singaporean guests, it seems that there is no connection, but if you put the affairs of these two places in the matter of 'Yanqiu' that she thinks is the most important, there may be a connection, but this is only an estimate, I think, we should go there immediately, and cooperate with the local police to handle the case, there will definitely be more situations into our sight. ”

When the captain heard this, he slapped the table and said, "Well analyzed!" In this case, I immediately asked the higher-level departments to try to work together to handle the case. Lao Chen, Xiao Zhang, you get ready, and set off for the northern city as soon as you receive the notice. ”

After the meeting between the three people, the police of the two places exchanged information.

In the end, the two places decided to join forces, and the police in the new place where the crime occurred in Kongyuan will send personnel to form a special case team with the two upcoming police officers to investigate the case and arrest the murderer.

The plane took off.

Xiao Zhang looked east and west excitedly, and said to Lao Chen, who was sitting next to him with his eyes closed, "It's the first time I've been to such a northern place." ”

Lao Chen's eyelids didn't lift, but he just let out a "hmm".

Xiao Zhang is still chattering: "My wife insisted on letting me bring a lunch box of fish floss she made, saying that I heard that there was no fish to eat in the north......"

Lao Chen raised his eyelids, didn't answer Xiao Zhang's words, and said indifferently: "After we get there, we have to find Zong Zhenlei first." ”
