"Check! Check it thoroughly! Shi Guoguo said expressionlessly.

……

The mourning hall was reopened, and Shi Guoguo and the old forensic doctor took the two policemen and the Deng family brothers to a quiet place for questioning to find out who Deng Qiangchang was with before his death, where he went, what he had done, and what he had eaten.

Deng Jingdong naturally knows everything and says everything.

Then Shi Guoguo asked those uncles and brothers Deng Jingdong who had eaten and drank together last night to question them one by one, and his own criminal police recorded and recorded them on the side, while I watched from the sidelines.

At half past eight o'clock in the end, Shi Guoguo ended the questioning and said to Deng Jingdong: "We have to go to the room where your father slept before his death, maybe there are some important clues!" ”

Deng Jingdong naturally nodded in agreement, but one of his uncles next to him said-

"There's nothing else in the room!"

Everyone looked at him, he was not nervous, but continued: "Brother Qiang Chang's room has been cleaned, except for his sister-in-law's clothes, they are placed elsewhere, and the quilts, mats, mosquito nets, beds, clothes and other daily necessities in the house are all pulled into the river and thrown away in the afternoon, and now it is just an empty house!" ”

Belch! And so it is!

When a person dies, all the things he wears with him are thrown away. Let's not talk about the auspiciousness of the things that keep the deceased, but those things are easy to make the family of the deceased look at things and think about people, and only add to the sadness, right? So this is a custom, and it is also a necessity of reality.

There's nothing wrong with that!

Shi Guoguo shook his head and smiled bitterly, feeling a big headache, it seemed that there was no need to look at the room anymore - did he still go to see how people were doing with hygiene?

The old forensic doctor seemed to wake up from his thoughts, and said, "I think there is any possibility—" and then paused, as if he had fallen into thought again.

I'm dizzy! Which one might you say? It's quite a pause, what kind of rhythm is this? It's really urgent.

The emperor is not in a hurry, who is in a hurry?

Shi Guoguo seemed to be very familiar with and adapted to the old forensic doctor's way of playing cards, so he sat unhurriedly and waited for the following, but Deng Shengxi was so aggrieved that he asked, "What is possible?" ”

Hehe, it's good that I didn't ask, otherwise I would be in a hurry. You must know that I also plan to write online articles if I have the opportunity one day in the future, in case I accidentally become a god of online writing, then it will be considered a counterattack in life, and the online writer is the most taboo The identity that is the first to be anxious - what identity? You know!

Hehe! Thank you, Second Brother Deng!

But the old forensic doctor didn't speak, but took out a pack of cigarettes - by the faint light nearby and my extraordinary eyesight, I saw that it was a real dragon - I heard that this cigarette was more than 50 yuan a pack, it seems that this forensic doctor's job income is good, how can he smoke such an expensive cigarette, or was it given by someone else?

It's just that when you take out this cigarette now, are you suggesting that the Lord should give you two packs? But on this occasion, there are no cigarettes, but there is a lot of incense, do you want to light a few?

The old forensic doctor slowly popped out one, not to mention distributing one to everyone, took out a lighter and lit it on his own, inhaled violently, but gently spit out the smoke ring - what the hell are you doing business, what are you doing here to be happy and better than the gods?

Deng Jingdong is a human spirit who has been mixed in society for a long time, how can he not understand these small doors? Seeing that the old forensic doctor was actually playing this trick at this moment and this occasion, although he despised it in his heart, he had to ask for others, and he couldn't swallow his anger for the time being, so he turned around and beckoned a cousin to go back to his home in the village to get it.

Suddenly, someone pulled the sleeve of his arm, and when he turned his head, he found that it was Shi Guoguo, the captain of the criminal investigation team.

Shi Guoguo's face was bitter, and he said in a low voice: "This is Wu Lao's habit of thinking, don't disturb!" ”

Others are human spirits, and Shi Guoguo is an expert among human spirits. Before someone else's butt pouted, he knew what someone else was going to pull, and as soon as he looked at Deng Jingdong's expression, he knew that it must have been misunderstood by Wu Lao for something again.

Wu Lao has this habit, he rarely smokes, but as soon as he smokes, he has to smoke well, and whenever he thinks of the key point, he forgets everything around him, and smoking is just a subconscious action, maybe he doesn't know that he is smoking.

But often at this time, this action is easily mistaken for a bad behavior of asking for cigarettes, money, etc., and similar jokes have been made several times before. Shi Guoguo and Wu Lao have been old partners for many years, how can he not know these habits? That's why Deng Jingdong's misunderstanding was stopped in time, and the image of Wu Lao was saved.

So that's it!

Belch! I also misunderstood this old man! I'm sorry!

After a few minutes......

The old forensic doctor Wu Lao suddenly slapped his thigh: "I understand!" He was supposed to be food poisoning! It's not someone else's murder! ”

"Food poisoning?"

It's not that everyone hasn't thought so, but Deng Qiangchang and Deng Jingdong eat and drink together, why are others okay, but he is dead? That's why the crowd ruled out this possibility.

Wu Lao affirmed: "It won't be wrong! I guess it was caused by eating seafood and then taking something else -- huh! It doesn't seem like there's enough! It shouldn't cause poisoning!? What's going on? ”

Belch! This old man will definitely be incomparably for a while, and then he will deny himself again!

Which play is this?

Shi Guoguo was silent, waiting for Wu Lao to think.

I couldn't help but ask, "Old Wu! Do you mean Uncle Deng ate seafood and something that caused arsenic poisoning? ”

Wu Lao glanced at me, and didn't blame me for interrupting his thoughts, took a puff of cigarette, and spewed out again, before saying, "Yes! Mixing seafood with vegetables and fruits high in vitamin C may cause poisoning, but this is only theoretically possible, but in practice it is almost unlikely. ”

He then explained that seafood, such as shrimp, crabs, clams, oysters, etc., contains the chemical element arsenic. In general, the levels are small, but increasing environmental pollution may cause arsenic levels to reach higher levels in these animals, while shells such as shrimp and crabs contain higher levels. The chemical valence of arsenic contained in shrimp (chemical valence is an expression of chemical structure) is pentavalent, and under normal circumstances, pentavalent o arsenic is not harmful to the human body. Theoretically, high doses of vitamin C (more than 500 mg of vitamin C at one time) and pentavalent o arsenic will be transformed into toxic trivalent o arsenic (i.e., trio oxo-dio arsenic, we often say "arsenic"), which can lead to human poisoning when trivalent o arsenic reaches a certain dose.

And vegetables and fruits also contain more vitamin C! However, according to scientific analysis, a one-time intake of 50 medium-sized apples or 30 pears or 10 oranges or eating more than 3 catties of raw green leafy vegetables is the intake of vitamin C in large doses. If the cooking process is heated, the vitamin C in the food will be greatly reduced. Therefore, it is not dangerous to eat fruits or vegetables while eating shrimp, as long as it does not exceed the above amount (I'm afraid no one can exceed it).

And Deng Qiangchang is naturally not the reincarnation of the pig king, so it is impossible to consume a large amount of vitamin C.

He ate the seafood, but where did his high dose of vitamin C come from?
