Police Detective

The Municipal Bureau of Homicide took this matter quite seriously and sent a detachment leader with four people, all of whom were capable people handling the case. The branch also sent the political commissar of the Criminal Investigation Detachment and several criminal police officers.

Bai Song sat next to Kong Suo, but he didn't attract much attention. From the beginning of the meeting, he was playing with his mobile phone next to him. There are many people in the police station, with three leaders and several auxiliary police officers present. This case needs to be continuously uploaded and handed down, and a lot of information needs to be integrated in time.

Every time there is a meeting like this for handling a case, it does not mean that the high-ranking officials sit inside. Anyone who is handling the case can come in, except for confidential cases.

Yan Yu didn't know how she woke up. She sat behind Bai Song with dark circles under her eyes. She didn't sit at the conference table. The only people who could sit at the table except Bai Song were over 30 years old.

In addition to Yan Yu, several other student police officers were also there. How could the students of the police academy not be curious when encountering such a murder case?

"The Lou detachment still doesn't believe it. This Shao Damu has lost contact. We found his friend. His friend said that he drank too much last night and vomited in the bar. He was picked up by his friend, but Shao was picked up by his friend. They don’t know Da Mu’s friends,” said Political Commissar Li from the Criminal Investigation Detachment.

"How dare you let others pick up Shao Damu even if you don't know him?" Kong Suo was a little confused.

"We checked the surveillance, and it was indeed picked up by two people. These are all good friends. If these two people can call out Shao Damu's name, it is enough to be trusted. Who cares about the others?" Political Commissar Li said: " We now suspect that these two people are the other two people with traces at the scene. According to follow-up monitoring, these people should have left the city, but it is not certain whether they changed cars and came back."

"Which direction does it leave the city from?" asked Detachment Wang from the Municipal Bureau of Criminal Affairs.

"In the direction of Tongxian County," Political Commissar Li said: "The surveillance cameras over there are still chasing. The car has been found. It is Shao Damu's car. The car will definitely be followed. The Lou detachment and the people have already chased it to Yanjiao."

"Well, there is still no problem with the Lou detachment's work." Wang's detachment nodded: "What did the forensic doctor say?"

"Come right over." Political Commissar Li looked at his watch and took out his cell phone to make a call. At this moment, someone pushed the door open and entered the conference room. It was the forensic doctor who was doing the test.

After the forensic doctor came in, he packed up the materials at hand and began to explain the situation directly.

"Let me read the anatomy. There is neurotropism in the brain tissue. There are no fractures in the whole body. There are many soft tissue contusions on the body surface, but none of them hurt the inner layer of the skin. There are no fractures in the hyoid bone and thyroid cartilage, and there are no fractures in the arteries and veins of the body. There are no abnormalities. The stomach contents are traces of crab meat and vegetables. There is some consumption of red wine. The stomach contents are about 100 grams. There are no obvious lesions in other organs and tissues." The forensic doctor who spoke paused and said, "Because of the use in this case. Difenidol is relatively rare. The test materials were sent to the Ministry of Physical Evidence Identification Center for urgent processing. Difenidol was detected in the blood and stomach contents of the deceased, and the content of diphenidol in the heart blood was 0.116 mg per milliliter. No other common poisons, sedatives, or stimulants were detected, and the test results for common drugs were all negative.”

"What was the concentration of alcohol and what was the cause of death?" asked detachment Wang.

"27, was in a drinking state, and the cause of death was determined to be difenidol poisoning." the medical examiner said.

"What is the lethal dose of this thing?" Wang's detachment then asked.

"There is no specific death data standard for this," the forensic doctor said with some uncertainty: "This is a drug used daily, and there is currently no official study on the lethal dose."

Looking at the still questioning look in Detachment Wang's eyes, the forensic doctor added: "I understand that if this thing is used normally according to drug standards, the blood concentration will not exceed 0.5 micrograms per milliliter."

"Isn't the one you just mentioned just past ten o'clock?" Political Commissar Li from the Chengdong Criminal Investigation Detachment asked.

"The deceased's body contained 0.116 milligrams per milliliter, which is 116 micrograms. The daily dosage is no more than 0.5 micrograms, which is more than 200 times the daily dosage." The forensic doctor said: "According to common sense, such a large amount of this type of drug is Will definitely die."

"Can this be included in the autopsy report?" Wang's detachment looked unhappy: "If the lethality is not known, how can we determine that the death was caused by this thing?"

"There is indeed no data on this." The forensic doctor was not happy either. He was also a veteran. It was already amazing that something like this could produce results so quickly. Is this still being questioned? No matter how city bureau leaders are, they are not as expert as forensic doctors in this area!

Talking about toxicity apart from the dose is a hooliganism. Basically, any drug has risks if its concentration reaches 200 times the intended use. Does this still need to be recognized?

"Are there similar data? What are the other cases of taking this defenidol?" Team Wang spoke more rigorously, and he still needed more detailed content.

"This" forensic doctor has a headache. This Wang detachment is really a bit expert, and the question directly goes to the key: "I have to ask carefully, this kind of thing is very rare."

Political Commissar Li saw this situation and came out to smooth things over, "This situation"

Wang's detachment looked a little unhappy, but he didn't say anything. He had to give some face to Political Commissar Li's words. Speaking of which, Wang's detachment's case-handling style is like this. He keeps asking questions to the end. He is also used to taking the initiative to analyze these things.

"I have data here." Bai Song put down his phone at this time, directly interrupting the conversation between the three of them.

Detachment Wang glanced at Bai Song, a little unhappy, thinking that this young policeman was playing with his mobile phone during the whole meeting. Now several leaders were chatting and interrupting, which was really ignorant.

Just as he was about to speak, he heard Bai Song start speaking directly: "Here are statistics on cases of taking diphenidol reported at home and abroad. The lethal dose is between 3-83 micrograms per milliliter. In some cases, every 3 micrograms per milliliter can cause death. If it really reaches 116 micrograms per milliliter, it must be more than the lethal dose, and far more."

"Where did you get this data from?" Detachment Wang frowned.

"It can be written directly into the final report," Bai Song replied.

"Who is this?" Captain Wang glanced at Kong Suo, then looked at Bai Song's police siren, a little confused, from the city bureau? Why haven't you seen him from the city bureau?

He hadn't looked at Bai Song's police signal before he came. Guan noticed that it was a young police superintendent. Now that he saw the police signal, he couldn't understand it.

"Bai Song from the Criminal Investigation Bureau of the Ministry of Justice." Bai Song directly reported his home address on this occasion, which would save a lot of trouble: "The data the forensic doctor just obtained also came from the Ministry of Physical Evidence Appraisal Center. I am also looking for friends there to continue the investigation. Got some information.”

Captain Wang did not continue to ask about Bai Song's situation and nodded: "What does Captain White mean?"

"Difenidol itself has the risk of death after taking a large amount of it, so when it is sold daily, the whole bottle only has 30 tablets, which is not too much. The bottles on site are also of the same specification, each tablet is 25 mg, and one bottle is only 25 mg. The content is only 750 mg. However, there is a case here where the deceased directly took 6000 mg of diphenidol to commit suicide. The blood concentration in the body was only 83 micrograms per milliliter. This means that the drug at the scene, Far from enough." Bai Song spoke very directly: "According to common sense, the deceased would have to consume at least ten bottles to reach a concentration of 116 micrograms per milliliter. I personally think that even if the deceased committed suicide, it would not be like this at all, and this case is not like that at all. Suicide, there aren’t enough bottles at the scene.”

"Why can you guarantee that the deceased will not commit suicide by eating ten bottles? Wouldn't this be safer?" Wang's detachment asked.

"Because the deceased was rich, I have counted cases of rich people committing suicide. Basically, they will not resort to such painful and torturous methods. Some even go abroad to use euthanasia. And rich people who commit suicide usually have a notarized will. It was not found in this case. Secondly, it would be understandable if all the bottles were taken away from the scene. The bottles left behind were obviously for us to see." Bai Song said: "These are enough to explain the problem."

"Which department of the Criminal Investigation Bureau does Team White belong to?" Detachment Wang frowned. He found that Bai Song hit the nail on the head with just a few words and directly found the key to solving the case. It can be said that this inference is a few steps forward.

"Case Disposal Section, Deputy Section Chief", Bai Song didn't care about this matter: "Detachment Wang, you understand what I mean, right?"

"Bai Chu", Detachment Wang seemed to know the configuration of the Criminal Investigation Bureau very well, and his attitude immediately turned 180 degrees: "Before I came, the leader didn't tell me that you were here, so I can tell everyone more about what you mean."

When Political Commissar Li heard what detachment Wang said, he couldn't help but sit up straighter. He couldn't help but look at Bai Song a few more times and wondered why detachment Lou didn't tell him this.

"Even if the deceased had a special constitution and a strong ability to absorb this drug, it is definitely not something that can be achieved by a bottle of medicine. Therefore, the medicine bottle at the scene should be an interference item. I am currently considering using self-purified or concentrated medicine. Poisoning." Bai Song said: "It is very difficult to purify the active ingredients of drugs, so in this case there should be people with relevant channels to purchase concentrated drugs, or there should be a high-level laboratory involved in the purification, possibly a corporate laboratory. Maybe it’s a university laboratory.”

After Bai Song finished speaking, Team Wang was about to speak, but Bai Song ignored him and went on to put forward his own point of view: "The binding traces of the deceased are obviously not fully controllable, and are more like some fun bindings. Other than that, In addition, the alcohol concentration of the deceased did not reach the level of losing consciousness. I personally have some experience with the traces of rope binding. This binding was not formed by the deceased himself, and judging from the traces of binding, he should be left-handed. It seems that this left-handed man was familiar with, or very close to, the deceased. He might be Shao Damu, or he might be another lover. "

Then, Bai Song thought for a while: "The process of difenidol first inhibiting the central nervous system, then excitating, and then inhibiting, and there are also some poisoning symptoms such as hallucinations, headaches, and joy, are very similar to some drugs. Maybe. We cannot detect the common ingredients of maphenidamine and phenylpropanol in the body of the deceased. We should also consider whether other ingredients such as coca, ketamine, methadone, and MA are present because of the presence of these rich people. They may not smoke those common things. We all know that those things are very harmful and the withdrawal symptoms are very miserable. I have thoroughly investigated some of the deceased's accounts and transactions every month through friends in the ministry. The capital flow rate is 57%, which is about more than 100,000. It is unclear. This may be the possibility of purchasing some illegal drugs. You must know that if this bad habit exists, you will be poisoned with high concentrations of difenidol. And the possibility of not saving oneself will be greatly increased. The direction of investigation should be relatively clear.”

"Bai Chu", detachment Wang was stunned when he heard this, "You went to the scene last night? Did you have a busy night? It's too hard for you."

"Yes, but I came back to sleep. Didn't I just tell my colleagues in the bureau about this matter? This was all based on the clues just fed back, so I didn't interrupt when you were communicating before." Bai Song said: "The current situation does not have strict logical reasoning, but it can be considered as an investigation direction."

"Um" Detachment Wang, who has always been a little proud, didn't know how to answer this sentence.

He habitually wanted to refute some of Bai Song's words, but finally nodded: "Now there are several more investigation directions, and they are all in line with the logic of this case. According to Bai Chu, the key to this case lies in the source of the poison. "

"Well, the main purpose is to investigate the identities of these people and who has such special channels." Bai Song said: "I personally recommend further increasing the background investigation of the deceased and related persons."

"This matter," Political Commissar Li glanced at Kong Suo, "Kong Suo, please give me your opinion."

Kong Suo was stunned for a moment, and wanted to stretch out his finger to touch himself, but finally stopped: "Political Commissar Li, we have quite a few people in our institute today, and those who can help will definitely do their best."

"Isn't Bai Chu here with you now?" Political Commissar Li said, "I mean, let's work together, work together, and then get the clues back and analyze them as soon as possible."

Bai Song looked at this with some helplessness. He suddenly discovered a problem, that is, his identity would probably be known to everyone tomorrow, and he couldn't hide it anymore.

In fact, this is a problem in itself. He has a certain reputation. Some young police officers have even seen him in newspapers and Weibo, and want to completely avoid him unless they disguise themselves every day. But that's not necessary.

However, even so, Bai Song still had to wear the clothes he was wearing now, otherwise he would be noticed too easily when he went out to police the people.

Seeing Bai Song distracted, Kong Suo pushed the topic: "Inspector Bai, if you have any specific arrangements, you can also mention them directly. We are here, including your junior brothers and sisters, so we can let them know more study."

What Kong Suo said was very accurate. They were older, so they were a little embarrassed to say "let us learn more", but Bai Song's junior brothers and sisters were here, so it didn't matter.

"Kong Suo," Bai Song shook his head lightly: "You should follow your working habits. Besides, what I said may not be accurate. This is just a family opinion."
