Chapter 66 Chapter 65

At noon the next day, Lin Jie went to the office to report to the two of them: "Boss, the results of the investigation of the Fan family case came out. The City Bureau Poison Laboratory extracted the remains of the milk, which proved that it was indeed arsenic poisoning, and the amount of arsenic in the milk It is very large, exceeding the solubility of arsenic in water, and the arsenic even exists in the milk bottle in the form of solid precipitation. The forensic doctor said that the murderer may have considered that milk has a protective effect on the gastric mucosa, so he put in a large dose of arsenic to ensure death. At the same time, an extremely small amount of sulfur was also detected. The staff took the same type of milk for a control experiment, and no sulfur was found in the control group, indicating that the murderer also put sulfur in."

Wang Gedong was puzzled: "What does that mean?" Lin Jie said: "The forensic doctor's opinion is that the arsenic used by the murderer was obtained from realgar through oxidation reaction. Because realgar contains sulfur, a small amount of sulfur is also mixed in the extracted arsenic trioxide." Wang Gedong looked at Zhu Guoshan: "The murderer extracted the arsenic from realgar, which can be bought everywhere. The investigation of this criminal tool is still the same as before, and cannot be carried out." Zhu Guoshan seemed a little helpless. He has been handling cases for decades, and the poisoning cases he encountered were also common cases in rural areas such as pesticides and rat poison. Dramatic drugs that are simply not available in the market.In particular, the murderer's poison was synthesized by himself using ordinary substances.He pursed his lips and could only say, "What about other situations?"

Lin Jie continued: "We have a large number of people checking and monitoring overnight, and restored the criminal history of the murderer. At 6:05 a.m. on December 22, less than five minutes had passed since the real milkman left the Dijingyuan community. The murderer rode a gray battery car into the community. There was an iconic milk box behind the battery car, which was probably fake. The security guards thought it was a milkman, so they didn't stop it. According to the later investigation and analysis, the murderer probably arrived on the battery Outside the door of Fan’s house, he used a screwdriver to pry off the real milk box, then took out the fake milk box, and connected it to the wall with quick glue. The key was left at the lock of the milk box, and the forged company notice was pasted on the box. Afterwards, Fan Changgen and his wife got the milk and were poisoned after drinking it.”

Lin Jie continued: "In addition, we found that a week before the incident, the murderer had entered the community many times disguised as a milkman, but the security guards didn't notice it once. It is estimated that the previous few times were for scouting spots and testing the security environment of the community. " Wang Gedong asked: "The murderer still hasn't shown up?" "Yes, judging from the back of the cyclist in the previous few times, it was still the fat man, wearing a hat and a mask, with his hands in gloves. But the person who committed the crime on the day of the crime, because of the snowstorm that started the day before , It was snowing heavily that morning, the surveillance camera was not clear, and the cyclist seemed to have lost weight.”

Wang Gedong and Zhu Guoshan were shocked, this time the accomplice appeared in the surveillance for the first time. Lin Jie continued: "However, he was still wearing a hat and mask. In addition to the weather that day, it was not bright at the time of the crime, and the light was dim. There is no way to determine the identity of this person." Wang Gedong thought for a moment, and said, "Send the video to my email, and I'll take a look. Is there anything else going on?" "Basically that's all. All the detailed reports are in this file. There is another thing..." Lin Jie looked embarrassed.

Wang Gedong looked at him hesitantly: "What?" "Received news from the police station in the morning that Fan Changgen's son and daughter brought a group of relatives and friends to break into He's house early in the morning, smashed the house, and injured people." "What!" Wang Gedong and Zhu Guoshan yelled at the same time, pale with shock. Wang Gedong hurriedly asked: "How is the person?" "He Jiansheng's mother was knocked unconscious and has been sent to the hospital. It is said that Gan Jianing's four-year-old son was also kicked unconscious in the chaos. He is also in the hospital. I just asked. Both of them are not in danger for the time being. , It’s just that the child may have been frightened, and after waking up, he didn’t cry or fuss, but his expression was numb, and he couldn’t say a word.”

Wang Gedong gritted his teeth angrily, and said, "How did Fan Changgen's son and daughter come to the He family?" Lin Jie hesitated, "I heard... I heard that people from the police station told them that their parents were killed by Gan Jianing's friends, so they called a large group of people to go..." "Where's the police station! Didn't I tell you before that I can't let anyone trouble the He family again!" Lin Jie said embarrassingly: "Those who went... Among the people who went there were people from their police station. Later... Later, a deputy director found out and brought other people to rush there, and then persuaded the matter and sent the person to the hospital Go, I just received the news."

"Fuck you bastard!" Wang Gedong couldn't help swearing, "Team Lin, you immediately bring the people from the county bureau to arrest everyone who made trouble in the morning, including those who participated in the police station!" Lin Jie was very embarrassed: "Boss, this...Although Fan Changgen is dead, other relatives of the Fan family are all in leadership positions. What happened in the morning...Fan Changgen's brothers and sisters were also involved. This...I'm afraid I can't catch it." Wang Gedong let out a long breath angrily, and remained silent.

Zhu Guoshan thought for a while and said, "I've also heard a lot about the Fan family in the past few days. It seems that the Fan family is very powerful in your county." Wang Gedong snorted coldly: "The old man who died in the Fan family was the former secretary of the county, and his children were all officials. They are all the leaders of the county and surrounding counties and cities, and the Fan family has a network of connections at the provincial and city levels, so there is nothing the Fan family can't do in the county." Zhu Guoshan nodded, and said: "At the beginning when Jiang Ping beat He Jiansheng to death, you couldn't even handle him. Now it's really not easy to arrest Fan Changgen's children because of the morning incident." He paused, and suddenly said coldly, "But this People will definitely be arrested."

Both Wang Gedong and Lin Jie looked up at Zhu Guoshan in surprise. "We can't catch the murderer now. The first job is to prevent the next murder. We discussed it yesterday. The murderer's target is divided into two categories. One is the person who troubles the He family. If there is trouble in the morning, maybe the murderer It soon became clear that the group of people in the morning would be in danger. We should arrest them first and arrange them to live in a hotel. We will talk about it later. The person in charge of the arrest, it is not convenient for you from the county bureau to come forward. I brought them here. There are more than a dozen people from the Provincial Department. In the morning, the Municipal Bureau also sent a criminal investigation team over. When the afternoon arrives, people from the Municipal Bureau and the Provincial Department will come to arrest them. When you meet the Fan family, explain it to them, and I believe they will understand. .”
