Chapter 118

Although we know what kind of substance isoflurane is, Chen Shi asked knowingly: "Captain Peng, what is isoflurane?"

"It's a kind of inhaled anesthetic for medical use. Its appearance is a colorless liquid with a certain pungent smell. Its chemical composition is stable and its biotransformation in the body is very few, so it's easy to detect."

"How can we find out? Isn't it an accident? "

"I pointed out this with Lin's team at that time. He sent someone to check. The dead man had been operated on for sinusitis the day before the accident. The hospital used this kind of anaesthetic. In addition, the dosage was not much, so it was not identified as intentional murder. Now it's mentioned 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 he used the same drug to harm him, so that he could not even be identified by the forensic medicine."

"Yes!"

Some people said: "but tiger poison does not eat son, how can his mother murder his own son, to cheat insurance?"

Someone else said, "I know this kind of medicine has a strong smell. How can the murderer let him inhale it into his lungs and mix it into the smoke to detect the taste right away?"

Peng sijue replied: "in the evidence of the deceased, no isoflurane remains were found."

Police officer Lao Zhang said: "I participated in the case. I learned from the relatives of the deceased that the child was not actually born by the couple. At that time, his father wanted a child, but his mother was unable to bear it, so he adopted one. When the boy was a child, he learned that he was not born in a quarrel between his parents. Since then, he had a bad relationship with his mother. So he died in an accident and his mother didn't even look at him. "

"I see. It's possible." Everyone said.

Lin Dongxue said: "I was on the phone with his mother. She said she would come back in two days to deal with the aftermath, which is a good opportunity for investigation. Before that, we have to collect more evidence to prove that she is suspected of fraud."

"If it can be proved from the source that it is to find the insurance agent named Yang, the woman will not break through," Chen said

But how to check? Everyone was at a loss. Xu Xiaodong raised his hand and asked, "team leader, who are those who cheat and protect?"

"People who are not rich."

"I'm not rich either, but I didn't cheat."

There was a burst of laughter. Lin Dongxue cleared his throat. "Most of these insurance fraudsters exchange insurance money for self harm. Some of them carry usury, some of them have patients in their families who need money, and some of them are drug addicts These drug addicts have been handed over to the rehab center after I contacted them. "

"If we pretend to be such a person in urgent need of money and find a way to buy insurance through this agent, can't we catch him?" said Xu Xiaodong

Chen Shi said, "the question is, there are many people who need money. How do you reach them?"

"People gather in groups and things are divided in groups. When I broke the drug trafficking case, I trained an informer. He knows a lot of addictions. Gentleman, maybe there's someone who knows the agent."

"You mean, you go undercover?" Lin Dongxue said.

"Yes, undercover! I love watching Infernal Affairs. Being an undercover agent is so stylish. Dongxue No, leader, you can satisfy my wish. Anyway, this case is not long-term. "

"But in case of danger."

"It's not a drug gang, a underworld, or a fraud case. It's not dangerous. I've practiced it!" With that, Xu Xiaodong made a duel.

Lin Dongxue ponders, and finally realizes that it's not easy to be a team leader. She has to take responsibility for the decision she made. She weighs it in her heart. The risk factor of going undercover is not high, and the time will not be too long. More importantly, she has the opportunity to contact the person behind the scenes.

Lin Dongxue said, "then you should be more careful and take all measures."

"Yeah, go undercover!" Xu Xiaodong raised his hands and cheered.

Xu Xiaodong's informant is actually his primary school classmate. He used to be a bully of the school. He often bullied Xu Xiaodong. When Xu Xiaodong saw him, he always took a detour. When he grew up, he mixed up with the society. Xu Xiaodong became a police officer. In a drug sweeping task of the criminal police cooperating with the anti drug brigade, Xu Xiaodong personally arrested him. When he was released, he nodded his head and bowed his back, the clearance between cat and mouse It's a swap.

Because this classmate Dai sinned and made contributions and reported some of his friends, his eldest brother sent out words to kill him, so he couldn't get along. Xu Xiaodong, out of pity, developed him into an informant.

Xu Xiaodong finds an informant ah Meng who works here in a KTV. Ah Meng says with a smile: "how can Dong Ge come today? Is there any task? Have you eaten? I'll invite you!"

"Stop being polite and tell you something. Let's find a quiet place."

Two people came to a private room, Xu Xiaodong explained the situation, a Meng scratched his cheek, "fraud protection Gang? I really haven't touched it. "

"Is there no treacherous one among your poisonous friends?"

"I don't know any poison friends. Since I was caught last time, I have completely changed my ways and never touched this again."

Xu Xiaodong sighs helplessly, takes out a wad of banknotes, a Meng grins and reaches for them. Xu Xiaodong shrinks back again and says, "only when you provide useful information can you get the bonus."

A Meng banged his teeth and said: "there was a man named Li Dechao who didn't see me for a while. When I showed up later, I found that he had a gauze in one eye and a huge sum of money on his body. He said that he had found a new way to make money. He didn't have to worry about no powder for at least five years I can swear that the powder he sucked had nothing to do with me. "

Xu Xiaodong sneers contemptuously. Few informants are clean. Even the undercover agents sent by the police, who are addicted to drugs, often leave behind the undercover agents. He shoves the prize money into a Meng's hand. "How can I find him? Don't hide it from me. I didn't check you this time. "

"There's a poison man tonight. He'll come."

"Gathering people to take drugs?"

"It has nothing to do with me. It really has nothing to do with me."

Xu Xiaodong thinks that this is for undercover, not for investigation. He has to make friends with the deceitful protector and set up intelligence. In that case, he will have to mix in and maybe get involved in drugs.

A Meng saw Xu Xiaodong's mind and said, "Dongge is afraid of getting addicted to drugs?"

"This kind of thing is ruined when it is touched."

"If you can trust me, I have an idea."

A Meng left the room and came back five minutes later. He took a straw and a bag of milk tablets. He ground the milk tablets into powder with a glass and handed the straw to Xu Xiaodong. "Try it!"

Xu Xiaodong knew it was a fake, so he took a straw to his nose, sucked the powder into his nose, choked him for a cough, and tears came out. Xu Xiaodong could not help saying, "the windpipe is going to be blocked. Next time, change the vitamin tablet."
