Although he knows what isoflurane is, Chen Shi still asks knowingly: "Captain Peng, what is isoflurane?"
"An inhaled anesthetic for medical use. It looks like a colorless liquid with a certain pungent odor. It has stable chemical components and minimal biotransformation in the body, so it is easier to detect."
"How did you find this out? Isn't it an accident?"
"I pointed out this to Team Lin at the time. He sent someone to investigate. The deceased had sinusitis surgery the day before the accident. The hospital used this anesthetic, and the dose was small, so it was not identified as deliberate murder. . Now that his mother is suspected of fraud, I can’t help thinking..."
"You think someone knew that he had used this anesthetic the day before, so they used the same drug to harm him, so that even the forensic doctor would not be able to find it out."
"Yes!"
Someone said: "But tiger poison does not eat children, how could his mother murder her own son to defraud insurance money?"
Others said: "I know this medicine has a strong smell. How can the murderer get him to breathe it into his lungs, so that he can immediately detect the smell if it is mixed into the smoke?"
Peng Sijue replied: "In the evidence of the deceased, no isoflurane residue was found."
Police officer Zhang said: "I participated in the case. I learned from the relatives of the deceased that the child was not actually born to the couple. Back then, his father wanted a child, but his mother had no fertility, so he adopted one. When the boy was a child, he learned that he was not biological during a parental quarrel. Since then, his relationship with his mother has not been good, so he died in an accident and his mother didn't even take a look."
"That's it, it's really possible at a glance." Everyone said one after another.
Lin Dongxue said: "I talked to his mother on the phone before. She said that she would come back to deal with the funeral in two days. It is a good opportunity for investigation. Before that, we have to collect some evidence to prove that she is suspected of fraud."
Chen Shi said: "If it can be proven from the source, that is to find the insurance agent surnamed Yang, this woman will not be able to defeat herself."
But how to investigate, everyone was at a loss. Xu Xiaodong raised his hand and asked, "Leader, who are the fraudsters?"
"People who are not economically rich."
"I'm not rich either, but I didn't swindle it."
There was a burst of laughter below, and Lin Dongxue cleared his throat, "Most of these fraudsters are self-harming in exchange for insurance money. Some of them carry loan sharks, some have patients in the family who need money, and some are drug addicts... These drug addicts have been transferred to the drug rehabilitation center after I contacted them."
Xu Xiaodong 丨 came up with a whim, and said: "If we pretend to be this kind of people who are in urgent need of money, and find a way to buy insurance through this agent, can't we catch him?"
Chen Shi said: "The problem is that there are many people who need money, how do you get in touch with them?"
"People gather by kind, and things are divided into groups. When I solved drug trafficking cases, I trained an informant. He knew a lot of addictions. Gentlemen, maybe there was someone who knew the agent."
"You mean, you go undercover?" Lin Dongxue said.
"Yes, undercover! I really like watching "Infernal Affairs". Being an undercover is really stylish, Dongxue... No, group leader, you can satisfy my wish. Anyway, this case is not a long-term one. ."
"But, in case there is danger."
"It's not just a drug-trafficking gang, a gang, or fraud. It won't be dangerous, and I have practiced it!" Xu Xiaodong made two gestures.
Lin Dongxue pondered. She finally realized that being a team leader is not easy. She has to take responsibility for the decision she made. She weighed it up in her heart. The risk factor of going undercover is indeed not high, and the time will not be too long. More important Yes, there is a chance to get in touch with the master behind the scenes.
Lin Dongxue said: "Then you should be more careful and take perfect measures."
"Yeah, go undercover!" Xu Xiaodong raised his hands and cheered.
Xu Xiaodong’s informant is actually his elementary school classmate. He used to be a bully in the school. He often bullied Xu Xiaodong. Xu Xiaodong always took a detour when he saw him. When he grew up, he mixed up with society. Xu Xiaodong became a policeman and worked with the criminal police to cooperate with the anti-drug brigade. During his anti-drug mission, Xu Xiaodong personally arrested him. After his release, he nodded and bowed when he saw Xu Xiaodong. The relationship between the cat and the mouse was reversed.
Because this classmate made meritorious service and reported some accomplices, his boss let out words to kill him, so he couldn't get along. Xu Xiaodong developed him as an informant out of pity.
Xu Xiaodong found Ah Meng, an informant who works here at a KTV, and Ah Meng said with a smile: "Brother Dong is free to visit today? Is there any task? Have you eaten? I invite you!"
"Don't be polite, tell you something, let's find a quiet place."
The two came to a private room, Xu Xiaodong explained the situation, and Amen scratched his cheek, "The fraud gang? I really haven't touched this."
"Among your drug friends, aren't there any fraudsters?"
"I don't know any poisonous friends. Since I was arrested last time, I have completely corrected myself and have never touched this again."
Xu Xiaodong sighed helplessly, took out a stack of banknotes, A Meng smiled and reached out to take it, Xu Xiaodong retracted his hand again, and said: "Provide useful information to get a bonus."
Ah Meng licked his teeth and said, "There is a man named Li Dechao who hasn't seen him for a while. When I showed up later, I found him with gauze in one of his eyes and a huge amount of money on his body. He said he had found a fortune. Xinluzi, at least five years without worrying about not having fans... I can swear that the fans he sucks have nothing to do with me."
Xu Xiaodong smiled contemptuously. Few informants are clean. Even undercover agents sent by the police, it is common to get drug addiction and leave a criminal record. He stuffed the bonus into Ah Meng's hands and said, "How to find him? Don't hide with me, I am not checking you this time."
"There is a poisonous party tonight, he will come."
"Gather a crowd to take drugs?"
"It has nothing to do with me, it really has nothing to do with me."
Xu Xiaodong thought about it, this is an undercover agent, not an investigation. He has to make friends with the fraudster and collect information. If that's the case, he has to get in, and maybe even get drugs.
Ah Meng saw what Xu Xiaodong was thinking, and said, "Brother Dong is afraid of drug addiction, right?"
"This kind of thing will be ruined if it touches it."
"If you can believe me, I have an idea."
Ah Meng left the private room and returned five minutes later. He took a straw and a pack of milk tablets. He crushed the milk tablets into powder with a glass and handed the straw to Xu Xiaodong, "Try it!"
Xu Xiaodong knew that this was going to be a fake, so he held a straw to his nose and inhaled the powder into his nose. He choked with a cough and tears came out. Xu Xiaodong couldn't help but said: "The trachea is going to be blocked. Change the vitamin tablets twice."
