As a police officer, you must be good at reading words and feelings. Pen ~ fun ~ pavilion www.biquge.info

Han Bo glanced at the deceased's husband a few times, and felt that he didn't look like a murderer, so he had a light meal at the substation, and rushed to the supermarket where the deceased worked before his death with Lao Lu.

The supermarket is a national chain, with three floors and a large scale, and next door is a mobile phone hypermarket.

There is a large flow of people and many employees.

Most of the salesmen and promoters of supermarkets and mobile phone hypermarkets ate lunch in the snack street at the back of the deceased. At the time of the meal, the business of small restaurants of various flavors is getting better and better, and it is impossible to sit inside, so the small tables are moved out, and many people eat outside.

A restaurant is not an ordinary kitchen, with many dishes and raw materials.

The health and epidemic prevention department did not have so many aflatoxin test strips, and the on-site test could not be detected at all, so they could only take samples and bring them back to the laboratory for testing, and only two were taken, and the other dozen or so planned to come back in the afternoon.

Wu Lanlan most likely died of poisoning from eating unhygienic food in these small restaurants, and the police of the sub-bureau who assisted the health department in the investigation did not dare to eat here, and they could not close the queue until they understood the situation, so they simply bought a few buckets of instant noodles in the supermarket, and made do with some supermarket employees who were reluctant to come out.

The sisterhood is deep, Wu Qingqing didn't go back, she asked for leave from school, the cause of her sister's death was not clear, and she wouldn't go back to school until her sister's funeral was over.

A person sits on a plastic stool in a daze, and he doesn't even know that his phone rings.

"Han detachment, Director Lu. Seeing the "young marshal" and the old forensic doctor, Liu Jingjun, the criminal police officer of the sub-bureau, and Lao Xu, the police officer of the police station, got up to greet each other.

"Sit down and talk about it after eating. ”

Han Bo pressed his hand, sat down next to the little girl and asked, "Qingqing, the noodles are almost soaked, why don't you eat some?"

"I can't eat it. ”

"I know you're sad for everyone else, but we have to look forward. You are sad, your parents are even more sad, you must be strong at this time, this family depends on you, only you can comfort them. ”

"I know, but I ......" Thinking of her sister who was still working here a few days ago, and thinking of her grief-stricken parents who were sending the white-haired man to the black-haired man, Wu Qingqing couldn't control her tears again.

There is nothing more painful in this world than life and death, people have just lost their loved ones, and it is useless to say anything comforting.

Han Bo is not a sentimental person, but seeing her sad appearance, he can't help but think of his elderly grandparents, his parents and fathers-in-law who are getting older day by day, and he feels very uncomfortable when he thinks that he will inevitably face the departure of his relatives in the future.

"Han detachment, we're ready. ”

Liu Jingjun ate a lot quickly, eating most of the bags of ham sausages by himself, drinking the noodle soup cleanly, throwing the garbage into the trash can, finding a rag to wipe the table, and taking out the notebook from the bag to report work.

"We just asked a few colleagues who had a good relationship with Wu Lanlan before her death, a few days after she had food poisoning, which small restaurants she went to before the accident, what meals she ate, what snacks she ate, and a few good colleagues had an impression and could basically recall it. ”

"At noon, I usually eat ramen, egg fried rice or duck blood vermicelli, just down the street for snacks. No. 17 seems to have bought roasted sweet potatoes, and he ate sticky corn bought by a colleague when he got off work. Eat small snacks with colleagues during breaks, mostly bought in this supermarket, bulk ......"

"Did the comrades of the Health Bureau take samples?"

"The sweet potato seller didn't come today, the corn was bought at the supermarket snack stall, the stall that sells roast sausages and milk tea in front of it, the epidemic prevention station took samples, and the snacks sold in the supermarket were also taken a little, and the small restaurant in the back didn't finish it, they said they would come back in the afternoon. ”

"Do you know which small restaurants you usually go to for dinner?"

"Yes. ”

"Let's go, let's see. ”

The first ramen shop, business is booming and overcrowded.

The people from the health and epidemic prevention station and the police came in the morning, but they didn't expect to come again, and the owner of the small shop was not very happy but did not dare to offend, so he turned back with the freshly cooked noodles and said: "Comrade Public Security, you have not come at the right time, there is no place to sit here." ”

"Leave us alone, you're busy. ”

"It's okay, it's okay, everyone continues to eat, let's just take a look. ”

After talking to the curious diners, Han Bo looked up at the menu posted on the wall, mainly beef ramen and egg fried rice, there were not many stir-fried dishes, not many cold dishes, and no one ordered.

The ramen noodles are boiled outside, and all kinds of seasonings are also placed outside, and the hygienic environment is very ordinary, and such a small restaurant cannot have high standards and strict requirements.

Cold dishes and stir-fried vegetables are made inside, the health and epidemic prevention department has come in the morning, and the inside has obviously been cleaned up, the kitchen knives are separated from raw and cooked, and the ground is washed with water, and it is wet. All kinds of materials and seasonings are placed on the shelf, and whether the aflatoxin exceeds the standard or not, it cannot be seen by the naked eye alone.

The deceased died of liver failure a few days after food poisoning, diarrhea for several days, her stomach was empty, and the forensic pathological examination could not detect anything from the stomach contents, and it is not known what she ate that caused the food poisoning.

A few of her colleagues knew that she had eaten here, but they didn't know what she had eaten. The scope of the investigation is not large, but it is not easy to find foods with excessive aflatoxins, especially raw materials.

After watching the flowers, after watching the first one, look at the second one.

When he walked to the third store and saw the dirty menu, Wu Qingqing suddenly said: "Officer Han, my sister likes spicy food, and she mentioned to me that the pepper fungus here is delicious." ”

In the morning, I saw bottled wild peppers in the kitchen of the deceased, not only wild peppers but also bean paste. As her sister said, she liked spicy food when she was alive.

Wild pepper is not a big problem, but it is difficult to say about fungus.

Han Bo put down the menu, turned around and asked, "Boss, how is this dish made?"

Delaying the business, the proprietress was unhappy, so she came over to take a look: "Cold dishes, cold salad." ”

"Let's go, go to the kitchen, please ask the chef to mix one for me on the spot." ”

"There's an empty table, sit here and wait, we'll pour you tea. ”

"No, I just want to see how to do it. ”

The people from the Health Bureau can't afford to mess with it, and the public security can't be offended, so the proprietress can only bring Han Bo and Lao Lu into the kitchen.

The restaurant is not big, a chef with two side dishes, the chef is busy with sweat, and the dishes are stacked in a row in a small stainless steel basin and waiting for him to fry, and the cold dishes are made by the side dishes.

Two policemen stared, and the chef of the side dishes paid as much attention to hygiene as possible.

Grab a handful of soaked fungus from the fresh-keeping box, have washed and picked, wash it again in front of the two people, drain the water, put it into a stainless steel basin for mixing cold vegetables, take out a few bagged bamboo shoot tips from the refrigerator, cut them into small pieces, and then chop the wild pepper, put it into the basin and mix it with monosodium glutamate, vinegar and other seasonings.

The action is swift, and it takes less than two minutes to get better.

It must be very crispy and sour to eat, but the fungus is not scalded with boiling water, and the tips of the bamboo shoots are raw, Han Bo and Lao Lu didn't dare to eat it, so they motioned to the chef to pack it in a plastic bag, and then grabbed a handful of fungus from the crisper box, gave 10 yuan, and put it in a plastic bag and took it away.

It's better to order more than one dish, as long as Wu Lanlan likes to eat or often eats it before her death, Han Bo simply asks several restaurants to make a portion.

By the way, Wu Qingqing was sent home, and it was half past one in the afternoon when he rushed back to the criminal technology center.

handed over a bunch of "takeaways" to the physical and chemical laboratory for examination, and took Lao Lu into the observation room next to the psychological testing room, and watched the deceased's husband accept a polygraph through the one-way transparent glass.

In the past, I had to ask my colleagues from the Jiangcheng City Bureau to help, but now I don't need to.

With the recruitment of new comrades and the presence of Zhou Suying, a psychiatrist and half a psychology expert, it is completely possible to carry out psychological testing. At this stage, it is mainly to provide technical support to the traffic management bureau to assist them in investigating some traffic accidents that are justified by the public and justified by the mother-in-law.

"Do you know about aflatoxins?"

"I don't know. ”

"Can the health products you sell treat high blood pressure, cholecystitis, and fatty liver?"

"Yes, it should be. ”

"Can or can't?"

"No, you can't. ”

"Do you know what bacterial food poisoning is?"

"I don't know. ”

……

There are many directions in biotechnology, although he majored in biotechnology on his graduation certificate, in fact, he did not learn much biotechnology, mainly in animal health, animal breeding, animal feed, and the polygraph results showed that he had never heard of aflatoxins.

At 2 o'clock, she wanted to attend the meeting of the detachment leader and the county (district) public security director for her partner, Zhou Suying didn't know that her partner was next door, so she asked more than a dozen questions repeatedly, and handed it over to the police in the psychological testing room to go first.

It is unlikely that the person who is being tested will commit a crime, and the reason why the test is only to confirm.

The two new comrades of the technical police, there are not many opportunities for polygraphing, unlike the DNA, trace and document inspection departments who are busy from morning to night, and simply treat him as a "guinea pig" and keep asking questions again and again.

In other words, Han Bo asked them not to toss, whether there is a suspicion of committing a crime, if there is any, if there is, if there is no, there is no.

But this guy is not someone else, but a bastard who has been swaggering for a long time and makes a living by swaggering, I don't know how many old people's pensions and farmers' hard-earned money have been defrauded, the public security has no right to investigate and punish him, but they can scare him and lock him up for 24 hours!

"Director Lu, let's go, let's go upstairs and have a look. ”

The old forensic doctor also hated this kind of charlatan, smiled meaningfully, walked out of the observation room with Han Bo, and took the elevator up to the third floor.

Changing into a white coat, walking into the experimental area of the physical and chemical laboratory, looking at the advanced instruments and equipment, and the busy young policemen, the old forensic doctor sighed sincerely: "The conditions are getting better and better, a hundred times stronger than when I was there." ”

"Why don't I find a way to transfer you back?" Han Bo asked half-jokingly.

"Don't, it's good to stay in the substation, even if you transfer back, you can't keep up with the times. ”

"Live to learn all the time, these are not as difficult as you think, let's check one, you are my assistant. ”

"Okay. ”

Not everyone can come in here, Lao Lu is very happy to go back to the old unit to help the old leader, the two took out a copy of the inspection materials, and got busy with Huang Zhiyuan and other technical policemen.

As long as you enter the laboratory, there is no time for this concept, and before you know it, three hours have passed, and just after filling out an inspection report, the technical police sent by the Anle Municipal Bureau for training suddenly exclaimed: "Han detachment, Director Huang, it has been detected, and the aflatoxins in the fungus are seriously exceeded." ”

The problem really was in the fungus, Han Bo looked at the data, turned around and said, "Check again, Director Huang, this time you come." ”

The stakes are so high that they must be examined twice by different appraisers.

Huang Zhiyuan agreed without hesitation: "Okay, I'll come." ”

The data of the second inspection showed that it was also seriously exceeded, Han Bo took out his mobile phone and made a call: "Director Wang, I have detected it here, the problem is in the fungus of the Sichuan restaurant, the deceased liked to eat his pepper fungus before his death, and others did not have food poisoning, the reason why she was poisoned has a certain relationship with personal taste and dish practices." ”

"Captain Han, what is the relationship, can you be specific. ”

"Sansho fungus is a cold dish, and the dried fungus is soaked and mixed directly, without boiling water, and no oil has been used. I saw the chef in this shop at noon to make other dishes with fungus, probably in a hurry, almost all of them were boiled with oil, the oil temperature was definitely more than 200 °, and the aflatoxin was basically killed, so eating mushu meat with fungus, fish-flavored shredded meat will not be poisoned, and eating directly cold mixed pepper fungus is very easy to poison. ”

Wu Lanlan ordered this cold dish, and others might order it too.

This is a matter of the health and epidemic prevention department, Director Wang did not dare to delay, and blurted out: "Captain Han, I immediately ordered the restaurant to close down, immediately report to the superiors, report to the Industrial and Commercial Bureau, and ask you to arrange for the police to assist us in investigating the source of the fungus." ”

"No problem, I'll call the sub-bureau and ask the sub-bureau to arrange for the police to assist you in your work. (To be continued.) )
