Chapter 67 Chapter 66

After Lin Jie left, Wang Gedong sat in the chair with his mouth tightly pursed.Zhu Guoshan comforted: "Okay, don't get angry about this anymore. I have encountered this kind of thing more than you, and the officialdom has always been favored by favors. Most of your inland counties and cities are family forces circling Rooting. In large coastal counties and cities, the most important thing is to stand on the team and follow up with real leaders. In the final analysis, it’s the same thing. You have to learn to adapt.” Wang Gedong nodded helplessly: "I know, I just feel uncomfortable in my heart!"

Zhu Guoshan glanced at him, didn't continue to say anything, and turned back to the case: "Let's take a look at the surveillance video of the Fan family this time." Wang Gedong turned his attention back to solving the case, opened the mailbox, and the two carefully watched all the surveillance cameras several times. Afterwards, he thought for a long time, and said: "On the day of the incident on December 22, the picture was too unclear and the light was very poor. , It’s snowing again.” "But the outline of this cyclist seems to be a little different from the fat man who stepped on the spot several times before, and he has lost a lot of weight."

"Looking at it this way, it wasn't the fat man who changed the milk crate on the day of the crime, but the accomplice." Zhu Guoshan's eyes lit up, and he said, "The three cases have something in common, and the accomplices all played a key role!" Wang Gedong suddenly excitedly said: "That's right, now it seems that except for the first time who killed Jiang Xiaobing is not clear, in the next two crimes, Fatty took care of all the crime preparations such as criminal tools, on-site inspections, etc., and in the end Those who commit crimes and kill victims are all the accomplices!"

"In the case of the Li family for the second time, the fat man left the community before Li Qiming's car drove into the community. The guy who replaced the milk box in the Fan family that day didn't look like the fat man. Now there is a problem, the fat man did it. With so much work, why doesn’t Fatty do it himself every time he finally kills someone, but let that accomplice do it? You must know that Fatty’s various preparations are the most difficult, and he has to show his face under the surveillance cameras , is dangerous, and in the final killing, one only needs to hide aside to operate the remote control, and one time only needs to change the milk crate, which are very easy things to do, but they are handed over to another person."

Wang Gedong pondered for a while, then slowly nodded his head, patted his thigh for the last time, and said: "There is only one explanation, that person is the main criminal, and the fat man is the accessory. The real planner is not the fat man, but the accomplice! That is to say The one who really wants to avenge Gan Jianing is not the fat man, but the accomplice! If the fat man is the main culprit, he is here to avenge Gan Jianing, then since he has done all the preparations, there is no need to share the simple operation of the murder with another One person. There is only one explanation, the accomplice wanted to avenge Gan Jianing, and he had a deep hatred with the victim, so that person had to carry out the final murder in person, so that he could vent his hatred. And that fat man just assisted that person in committing a crime. "

Zhu Guoshan thought for a moment, and said: "But now there is a contradiction. If the fat man is an accomplice, and it is the accomplice who really wants to avenge Gan Jianing, then the accomplice and Gan Jianing should have a close relationship. The accomplice must be one of the car owners who passed by Anle Road. But you have investigated all these car owners, and none of them have a chemical background, let alone Gan Jianing’s classmate. The contradiction is that the main criminal who wants to avenge her, that is, the accomplice, does not have a chemical background, and of course he cannot be her classmate And the fat man who assisted in the crime has a very professional background in chemical engineering, and may be a classmate of Gan Jianing. The relationship between the characters is confusing."

Wang Gedong suddenly fell into hard thinking: "If this contradiction is established, then there are infinite possibilities for the investigation target. One is that the fat man is indeed Gan Jianing's classmate, and the principal culprit also met Gan Jianing through the fat man. The fat man used his professional knowledge to provide Assistance. Another possibility is that the principal culprit is not Gan Jianing’s classmate, but a person who has a deep relationship with Gan Jianing. As the assistant, Fatty studied chemical engineering, but he is not Gan Jianing’s classmate. Maybe he graduated from another school’s chemical engineering. Then the investigation will be fundamental Can't expand."

Zhu Guoshan frowned and said: "The crime process was originally very clear, but because two people committed the crime together, our investigation fell into a complicated and confusing circle. If there is only one murderer, that fat man, then we can also clearly and directly investigate Gan Jianing Now two people, who is the main criminal who really came to revenge, and who is the accessory, there are two possibilities. The professional background of the main criminal also has two possibilities. Whether the accessory is acquainted with Gan Jianing, or just to help the main criminal, there are also two possibilities Two possibilities. Multiplying two by two, there are now eight possibilities. In addition, there are more possibilities for the relationship between the principal criminal and the accessory criminal, such as friends, lovers, etc. Hmm... the more the case is analyzed, the more complicated it becomes. "

Wang Gedong looked a little frustrated: "If it is true that the fat man is an accomplice rather than the main culprit as analyzed today, then the work of investigating Gan Jianing in the early stage will be in vain." Zhu Guoshan nodded and admitted: "This time the murderer's criminal ability, criminal details and anti-reconnaissance awareness are unprecedentedly strong. Every time he kills with chemical poison, he can kill the person without direct contact with the victim. The poison he chose for the third time The difference is that the first time nicotine was used, the dose was small and the effect was quick. The victim fell into a coma before he was fully awake and then died. The second time he used hydrogen cyanide. Since he chose the spray bottle device, the liquid hydrogen cyanide is the most effective. Good choice. Because nicotine is difficult to purify, it is very troublesome to get a bottle of nicotine, so hydrogen cyanide is synthesized directly. The third time I used arsenic trioxide, which has a slow onset, but also cannot be rescued once an attack occurs. It can be seen that the murderer is also Foreseeing that Fan Changgen and his wife may not drink milk together at the same time, if they use the quick-acting milk, one of them has not drunk it, and the other has an accident, so it is impossible to kill the husband and wife. In all previous crimes, the murderer has never Leaving key evidence, I tried my best to avoid the monitoring probes outside the crime scene, which proved that the preliminary work of the environmental survey was also done very well. Even when changing the milk crate, I thought of waiting for the real milkman to leave after delivering the milk. I have never heard of such an opponent."

Wang Gedong smoked a whole cigarette, squinted his eyes slightly and said, "Now there is still a doubt, how did the murderer know that the Fan family ordered milk." "The murderer went into the community to check the spot, and he knew it when he saw the milk box in front of Fan's house." Wang Gedong shook his head: "The murderer can't determine which villa in the community belongs to Fan Changgen's family. We asked the security of the community, Dijing Garden is usually very tight security, except for newspapers and milk deliverers, other people have to enter the community. Strict identity registration was carried out, we checked the visitor records for nearly a month, and no suspicious person was found for the time being. And I went to Fan's house to check carefully, and there was nothing outside the house that could prove the identity of the owner."

"Fan Changgen's car should be known by many people, right?" "However, there are parking garages in the courtyard of the villas in the community. The garages are on the back of one side of the wall. Looking in from the outside of the villa, you can't see any cars parked in the warehouses. We also asked Fan Changgen's children. Fan Changgen's car has been parked in the warehouse. It will not park directly in the yard." "Does anyone else know where Fan Changgen lives?" "Ask the people in their police station, and many people know that he lives in Dijingyuan, but not many people in the same unit know the specific house and household. The private residence of the leader has always been kept secret, and Fan Changgen is no exception. Besides, we checked found Fan Changgen's car, but no tracking and positioning device was found." Zhu Guoshan was puzzled: "Could it be that the real milkman revealed it?" Wang Gedong still shook his head: "Yesterday we strictly interrogated the milkman, and his statement was flawless, and we asked his unit, he has been in charge of milk delivery in this area for several years, and there is no possibility of being involved in any crime. He also said that he has not been in contact with other people recently, and no one has asked him about the situation of Emperor Jingyuan." Zhu Guoshan closed his eyes wearily: "It seems that only the murderer himself can answer this question." Wang Gedong shook his head unwillingly, he believed that any doubtful point in the case would most likely become a breakthrough in the investigation.Now there are many unsolved doubts and possibilities in the case. Which direction is the breakthrough? He was lying in the chair, frowning and staring, contemplating deeply. As long as there is a crime, there will always be clues. Well, it is necessary to analyze the three cases again from beginning to end to determine the final direction of detection.
