The two quarreled for a few words, and then hung up the phone, without Zhou Ning's instructions, Zhu Xingxing had already dialed Cui Lili's mobile phone, and as soon as it was connected, Zhu Xingxing sent the mobile phone to Zhou Ning.

"Eldest sister, if the blood in the deceased's heart is sufficient, add a test to check the vitamin A content in the deceased's blood, can this be done?"

Cui Lili paused, obviously laughing at Zhou Ning's question.

"Can you do it, the results will be available tomorrow morning at the earliest, can you wait?"

Zhou Ning smiled, how could he not wait, after all, it takes two or three days to take this test in the hospital.

"Okay, I'm sorry for the trouble, big sister."

Hanging up the phone, Liu Yufei couldn't hold back, and hurriedly asked:

"What do you mean? The deceased was not poisoned, no, it should be said that it was not organophosphate poisoning, but the vitamin A poisoning you mentioned, so the deceased had so many symptoms and was emotionally out of control? Is that what it means?

However, can vitamins still be poisonous? ”

At this time, a person sat up from the chair, yawned, and looked at a few people, Zhou Ning didn't expect that Peng Shinian would actually sleep here.

In July 2012, in a professional journal in the United States, such a case was reported: in order to prevent her from catching a cold, the parents of a 3-year-old girl actually gave her 100 times more vitamin A than the usual amount every day for a month, which caused the little girl to itch, dehydration, convulsions and other symptoms, so that the heart stopped beating.

The symptoms of vitamin A poisoning are generally manifested as lack of appetite, itchy skin, dry hair, hair loss, chapped lips, irritability, bone pain, fractures, increased intracranial pressure, etc., which is still a reaction to chronic poisoning, which can be fatal if ingested in large doses in a short time.

For example, the famous Australian explorer Douglas Mawson went to the South Pole in 1911, and when they arrived at the South Pole, supplies were lost, and Mawson killed the only sled dog, hoping to survive the harsh weather by eating dog meat.

A few days later, his companion died suddenly, he thought he was frozen to death, and when he returned to Australia after surviving the snowstorm, he asked a biologist to find out the real cause of his companion's death, it turned out that the companion thought that the meat was too hard to eat the liver, and the liver contained a large amount of vitamin A, which led to acute poisoning of vitamin A. ”

Zhou Ning couldn't help laughing, and Liu Yufei nodded stiffly.

"I understand, a large dose of vitamin A can be fatal, but this ultra-high value item found in the deceased's body will not reach the amount of poisoning death you are talking about, right? You're not a Ph.D. in entomology and botany, so you know that? ”

In a word, the moment Peng Shinian was blocked, he was speechless, Da Zhao came over with a smile, blocked in front of Peng Shinian, and winked at Liu Yufei.

"Dr. Double is not joking, this just means that these two aspects are the best, not only understand these two aspects, we poets have recently preferred to study the toxic side effects of various plants and animals in the Kotoshima area, right?"

Peng Shinian nodded and pushed his glasses.

"If this person suddenly has a big mood swing, it is really possible that he has ingested a large amount of vitamin A in a short period of time, and he can go to the deceased's house to have a look, isn't it impossible to determine the nature of the case now?"

Zhou Ning's eyes lit up, not to mention that Peng Shinian's idea was indeed right, even if it was ingested in large quantities in a short period of time, it was not eaten in one or two meals, this thing was fat-soluble and greasy, how could it be possible to eat so much at one time?

Do you drink oil?

Of course, it is possible that it is not the mouth that drinks oil.

Even if it is Kaiseru, it is directly excreted after lubrication, and it will not accumulate in the body.

Zhou Ning clicked on his mobile phone and searched for various dosage forms of vitamin A on the market, most of which are soft capsules, with a maximum dose of 25,000 units, and 100,000 units per day for 3-6 months to cause chronic poisoning.

Of course, a single intake of 1 million to 1.5 million units can cause acute poisoning, but the physique is different, and some adults ingesting 500,000 units can also cause poisoning reactions.

Seeing this, Zhou Ning hurriedly put away his mobile phone.

"Zhu Xingxing sent the deceased's liver and stomach bottom slices to the laboratory, do not test the blood in the heart, directly check the accumulation of vitamin A in the liver, and if you take a large dose in a short time, it will be stored in the liver."

Zhu Xingxing hurriedly ran away, and Liu Yufei frowned.

"In this case, Director Zhou, you come with me to the front building, prepare the items for investigation, ask the address of the deceased, and then go directly to the scene to take a look, a large dose of intake, there is always a way, they ate Mr. Li's beef noodles at noon, if there is a problem in the dish, Kong Wanshan will also have symptoms."

Zhou Ning raised his hand and interrupted Liu Yufei's words.

"Wait a minute, let's go to the front building, take blood for Kong Wanshan, do a test, see if the vitamin A in his body exceeds the standard, Da Zhao will bring all the survey tools, and we will go with Liu Da."

Peng Shinian stood up and quickly took off his white coat.

"I'll go and see it too, take me with me."

Zhou Ning nodded.

Everyone followed Liu Yufei to the front building, Fang Mu was still interrogating, Liu Yufei took Da Zhao in, and directly drew blood for Kong Wanshan, Kong Wanshan looked confused, although he didn't know what they were doing, but he didn't resist too much.

Da Zhao went out to send for inspection, and Kong Wanshan stared at Liu Yufei in the interrogation room, Liu Yufei said:

"Does Li Li know that you have a family?"

Kong Wanshan nodded.

"I know, my second child dances in Li Li's dance school, this child has to let me pick me up, her mother also has to pick up the eldest to learn Go, so we know each other, Li Li is very good to my second child, and my daughter-in-law also invited her to dinner.

We've known each other for almost five years, but it's only been two or three years to have a relationship with her, she has been a demon during this time, wanting me to divorce and marry her, even for the sake of two children, I can't, the eldest is fourteen and the second are twelve, if at least one of the divorces can't live with me, I can't accept it. ”

Zhou Ning raised his eyebrows, but he didn't expect this Kong Wanshan to explain carefully.

When Liu Yufei heard him say this, she didn't mean to leave in a hurry, leaned back on the chair, looked at Kong Wanshan with her arms crossed, and asked seriously:

"Does your daughter-in-law know you're having an affair?"

Kong Wanshan's head shook like a rattle, and he said very firmly:

"I don't know, she is busy with two children every day, and she has to take care of the food and clothing of the family, my father is still in the hospital, and needs someone to take care of him for a long time, although there are nurses, but every day she passes, if she knows she will not do this.

Moreover, we are a poor couple, when she and I were a small material clerk, no culture, and then followed a period of supervision, some ways, then began to package the project, step by step to the present, six years ago only had their own real estate company. ”

Kong Wanshan said in a hurry, when he asked him other questions before, he was in a very indifferent state, and he could feel that he didn't want this matter to involve his daughter-in-law, which was a little unexpected.

Maintain your image as a good husband and father?

Or, do you really have feelings for your daughter-in-law?

As soon as the door of the observation room rang, Da Zhao came back, and seeing the strange expressions of Zhou Ning and Peng Shinian, Da Zhao had a gossipy look on his face.

"What's wrong? During the time I was away, what did he say, hurry up and share it with me. ”

Zhou Ning didn't say it, Peng Shinian lowered his voice, and after learning it again, Da Zhao rubbed his chin and stared at Kong Wanshan as if he was analyzing, don't look at Da Zhao's chubby and honest appearance, in fact, his sensitivity is very high.

"Tsk, I think it, he has today's career, and his daughter-in-law must be inseparable, although such a person is fluttering outside the flags, he still hopes that the home is peaceful, the daughter-in-law takes care of his own children, and his parents, more than how much money is spent on hiring are at ease, as for the three children outside, that is, playing.

We had a car accident at noon, and when he came to deal with it, he coaxed Li Li's appearance, how to say that it was very spoiled, but it was also a kind of tolerance for good things, once such a relationship threatened his family, he was probably cleaner than anyone else, by the way, that Li Li didn't have a dance school, let's not take a look? ”

Zhou Ning nodded.

"Let Zhang Qiangmin send two trace checkers to follow, let's go separately for a while, they go to the dance school, we go to Li Li's house, today is Sunday, it is estimated that the people in the dance school are more together, you can learn about Li Li's social relations."

Da Zhao smiled.

"Yes, if you can hook up with a Kong Wanshan at school, there may naturally be a second or third, according to what he said, I have known Li Li for five years, and I have only been together for three years, or after he established a real estate company, this is remarkable!"

Listening to Da Zhao's words, Peng Shinian nodded vigorously.

"I've found that you're really analytical."

Da Zhao sneered and laughed, hugging Peng Shinian's shoulder.

"I said poet, I've seen too much, after all, the relationship between the living environment, encountering such and such things, it can be said that it is not uncommon, some people want to be on top, all kinds of means are available, absolutely refresh your social cognition, they also asked, let's go and see."

Sure enough, the next door had already dragged Kong Wanshan up, and did not handcuff him, his face was somewhat panicked, and he glanced at the clock, the time shown on it was 16:44.

Peng Shinian poked Da Zhao's arm and approached him.

"This man has looked at the time several times, what is he going to do, what time is he going to miss?"

Da Zhao thought about it and snapped his fingers.

"According to what you said, he just said, to send the second child to dance, he usually picks him up, it is estimated that it is almost time to pick up the child, we have to go to the dance school, I guess I am afraid of running into my daughter-in-law."

Just as they opened the door of the observation room, Kong Wanshan next door grabbed the door frame and prevented everyone from leaving.

"What, comrade policeman, can you wait a little longer before leaving, my daughter-in-law will pick up the child immediately, I don't want her to see me coming with you."

Liu Yufei nodded.

"You go with us to Li Li's house, my colleague goes to the dance school to investigate, let's go, don't waste time, otherwise I will also find all the parents of the students to the dance school for inquiry."

Kong Wanshan breathed a sigh of relief and hurriedly said:

"This is a traffic accident, why are you staring at me, the car was indeed given to Li Li by me, but it's been more than half a year, can she blame me for her accident?"
