Cheng Bin has a big weakness,

Just afraid of dogs.I was chased by a dog when I was a child,

Since then, every time I see a dog, it is like seeing a ghost.

While at the police academy,

Every time Cheng Bin sees a police dog, he can't move.

Yu Renjie likes to walk the dog to show him the most,

Almost every dog ​​in the school has been fed by him,

Then at the sound of his voice he sticks out his tongue,

Drooling instinctively.

Just now Yu Renjie was disparaged by him because of dizziness, and he was very unhappy, so now he is very happy,

Not only did he not help drive the dog away, but he also broke Cheng Bin's hand that was tightly wrapped around him, bent down to pick up the puppy,

Squeeze the puppy's paw to touch Cheng Bin: "How cute is the puppy,

How can you be afraid of dogs, a big man?woof woof! "

Cheng Bin was so frightened that he hid in the far corner of the sofa and almost didn't fall.

He cried out in panic,

let him help,

I still don't forget to scold a few words from time to time: "You wait,

See how I deal with you!Do you want me to pay you back! "

Seeing Cheng Bin's face turned pale,

Only then did Yu Renjie take the dog away,

Give it to Li Fang: "My colleague is afraid of dogs, do you think this dog can be locked up first?"

After seeing off the neighbors at the door, Li Fang apologized to Cheng Bin: "I didn't know you were afraid of dogs,

I'm really sorry,

I'll put it in the kitchen right away.Why don't you wait for me, and I'll prepare some breakfast for it first. Dogs, like humans, have to eat three meals a day. It's really troublesome. "She said and drove the puppy into the kitchen, and Yu Renjie followed in. He picked up the puppy, afraid that it would run out again.

Li Fang grabbed a handful of dog food into the dog bowl, took out a chicken leg from the stove, tore it into pieces and mixed it into the dog food.The dog bowl was bright red and shiny, with a pattern of a bone printed on it. As for the smell of a bitch, Yu Renjie also smelled a bit of plastic.After feeding the puppy, they returned to the living room, and Li Fang explained to them: "I was afraid that there would be no one at home when you came, so I asked the neighbor next door to help me walk the dog. Where were we talking?"

"Speaking of why the police didn't do an autopsy." Yu Renjie reminded.At this time, Cheng Bin's face was still pale, and he was staring at the kitchen door, refusing to let go.The kitchen door was translucent, and the puppy was pulling on the door, pressing his face against the frosted glass, and his nose was deformed.Yu Renjie couldn't help looking back and forth at them a few more times, and his heart blossomed with joy.

"Why didn't you do an autopsy..." Li Fang stroked her loose forehead hair, and slowly replied: "It was a coincidence that day, my husband drank a little green tea while eating biscuits, and it was on the news a few days ago Kind of."

Li Fang said that after Wu Zhiyong collapsed, the first thing she suspected was not the biscuits, but the box of green tea.She bought the biscuits from a small shop that she had patronized for many years, she was relieved, but the green tea was in the news, and several people were poisoned to death two days ago.So when the police came, she handed over the leftover green tea, saying she suspected it was poisonous.She checked the information on the Internet after her husband was poisoned, and this box of tea happened to be the batch that was rumored to be poisoned.But the police reassured her that the information on the Internet was all fake. Green tea was not poisonous at all when it was produced, and it was dropped after entering the convenience store, and the poisoned boxes had all been recalled.Coupled with her husband's case information and the emergency doctor's judgment, Wu Zhiyong's cause of death was quickly determined to be acute cerebral infarction.

"Fortunately, I read the news and Lao Wu's body hasn't been cremated yet. Isn't it too late to find out the cause of his death?" Li Fang asked, wiping away tears.

At this time, Cheng Bin was still looking in the direction of the kitchen, but he was able to organize his thoughts and answer: "Our colleagues will check your husband's body later, and conduct an autopsy if necessary, and you will need to go through the relevant procedures at that time. "

"That's no problem. I'm retired and I have plenty of time." Li Fang said, pushing the fruit towards them for the third time: "You are welcome."

Yu Renjie reached out to the fruit, but seeing Cheng Bin's eyes, he scratched his nose instead: "By the way, where are the biscuits you mentioned? Are they kept according to our requirements?"

"Yes, yes, I didn't throw away the biscuits, I put them in a moisture-proof place without moving, I'll fetch them for you right away." Li Fang struggled to stand up against the sofa, and beat the back of her thighs as she walked, The back looks very much like an old man in his 80s and [-]s.

The biscuits are stored in an orange tin tin hidden behind the door of the TV cabinet.Li Fang opened the jar and handed it to Yu Renjie: "Do you see if it is this kind of biscuit? I think it is the same as the one in the news." The word milk powder was written on the surface of the jar, which was originally used to hold adult milk powder.

Yu Renjie nodded: "Yes, that's it."

"Are you going to take it back to the police station for testing?"

"Yes, you are right."

"Will you notify me when the result is available? If possible, I want to know the result as soon as possible."

"Nature will notify you, please rest assured."

"Oh, if there is a result, will you give me a paper explanation? It's a proof of the cause of death. I have seen it in TV dramas."

"This will be there, and I can bring it to you."

"Okay, thank you, I see."

"Ms. Li, let me confirm with you again, when did you buy your biscuits?"

Li Fang was stunned for a moment, then stammered: "Okay, okay, I bought the biscuits at noon the day before yesterday, and I happened to go out for a stroll that day."

"What time is it?"

"Eleven or twelve o'clock."

"Okay, got it."

When Cheng Bin and Yu Renjie got up to leave, the aunt next door came again and looked in at the door: "Li Fang, I'm here to ask you, do you want to come to my house for dinner at noon? Something happened to your house in the past two days, it must be I'm very busy, so come to my house to eat, I bought a roast duck."

This day, Cheng Bin and Yu Renjie wore police uniforms for a rare occasion. As soon as they saw the uniforms, the aunt rushed into the room in a hurry, pulling the two of them to talk nonsense: "I have always said that Li Fang's life is really bad." Good. Marry a husband. My husband has a bad temper. He has a bad temper. His blood vessels are bursting. Let’s have a son. The son is not sensible. He is in his thirties and doesn’t know how to take care of himself. This is a big worry. And I have to worry about the little ones, the burden of the whole family falls on the shoulders of a woman, I saw her with my own eyes, she has aged a lot, she was still a beauty before!"

"Oh, don't say it, don't say it, it's in front of her!" Li Fang kept pushing her away.

"I just want to say it in front of them!" The aunt held on to the wall firmly and refused to leave: "Who in the community doesn't know Li Fang. When you talk about a woman pushing a wheelchair, you know it's her. My husband is paralyzed." For so many years at home, I have been taking good care of such a thin woman, pushing a big man around every day, cooking for him in different ways every day, all healthy food... I told her that your man is useless I want him to live longer, I'm really afraid that she will walk in front of her man!" At this point, she turned around and patted Li Fang on the shoulder: "Don't be too sad , I don’t think it’s all a bad thing for you two that he’s gone, without his burden, your life can be easier.”

Li Fang's face was very ugly, and Cheng Bin and Yu Renjie were a little embarrassed among them, and they didn't know what the neighbor aunt's intentions were when she said this to them, but the auntie quickly found her way back: "Li Fang is a good person, and the fate It’s very hard, you must help her! Hurry up and catch the murderer. If there is any compensation from the government, you must tell her. You can tell me, I will work with her as a staff.” After a long time, it turned out to be for the benefit of the neighbors.

After finally getting rid of the warm-hearted neighbor, Cheng Bin threw the key to Yu Renjie when he found the police car.After being thrown by a puppy, his legs are still weak and his hands have no strength. For safety reasons, Yu Renjie drove the car afterwards.

Before returning to the police station, they went to a nearby vegetable market and confirmed with the proprietress of Haiyan Food Store when Li Fang went shopping.The proprietress really remembered that Li Fang had been here, and she still remembered that she bought seaweed and egg rolls: "That wheelchair pusher, I have an impression! She is quite a person, and the egg rolls are not broken at all. Be sure to pick a good one and buy an egg roll." I bought it for a long time. Yes, yes, she also bought biscuits, but I forgot the last one, look at my memory." When asked about the exact time, the proprietress was not very sure: "It was quite bright at that time, not at noon It's afternoon, about this time."

When he returned to the police station, Cheng Bin was still in a daze and mistook Xiao Mi's plush doll for a puppy. He screamed in panic, and when he realized that it was the toy that scared him, he grabbed it angrily and beat it hard. He threw it on the ground: "What are you bringing such an ugly thing to the office for?"

Xiao Mi's doll is indeed a bit ugly, with a white body and a white head, with two protruding balls sewn on the head for its eyes, and a golden horn standing in the middle.Xiao Mi said it was a beautiful unicorn, but colleagues all called it the King of the Golden Horn.

When Cheng Bin rushed back to his office in a fit of rage, Xiao Mi patted her king distressedly, cursing Cheng Bin in a murmur, Yu Renjie pricked up his ears, and only heard the sentence of seven consecutive days of constipation.Even if she has a bit of conscience, she will probably see Hades after seven days.

In the afternoon, Hao Jinyang's nosebleed stopped, and he became arrogant again, asking around Yu Renjie, asking where he went this morning, who he met, what he did, etc. Yu Renjie threw the biscuit bucket to him: "You Send this barrel of biscuits to the forensics department, and let them test it quickly. Also, help me find out if the deceased has bought insurance."

Hao Jinyang responded and found that Wu Zhiyong's name was written on the note.Before he left, Yu Renjie called him back again: "Wait, check the insurance status of all the deceased."

The results of the chemical test came out soon, and the poisonous substance was indeed found in Wu Zhiyong's body, and the same toxin was also found in the biscuits retrieved from Li Fang's home.The layer of powdered sugar on the surface of the biscuit was mixed with poison rat|strong powder, consistent with biscuits previously recovered from other victims.

The report pointed out that these biscuits have one thing in common, and the experimenters have detected a special ingredient in the biscuits-potassium sorbate.Potassium sorbate is a common food additive used for food preservation, but the state clearly stipulates that it is not allowed to add this ingredient when making biscuits.After confirming with the biscuit manufacturer, except for the sandwich biscuit that may contain a little potassium sorbate in the products manufactured by the manufacturer, none of the other products contain this ingredient, and the poisoned biscuit this time did not have a filling.

In the follow-up experiment, the experimenters took samples of the biscuits provided by the manufacturer, the biscuits recovered from the warehouse of Haiyan Food Store, and the biscuits provided by enthusiastic people, and analyzed the components by gas chromatography.Experiments have found that these biscuits do not contain potassium sorbate and do not contain tetramine.So how did potassium sorbate get into the poisonous biscuits that killed people?Is it because Potassium Sorbate contains Potassium Sorbate in the first place, or did it get contaminated with this food additive during the poisoning process?

The laboratory has done more analogy experiments. Among all the biscuits recovered from the proprietress, the biscuits stored in the warehouse are non-toxic, and some of the biscuits on the counter are poisonous-in general, the upper layer of the bag contains poison rat|strong, The lower layer is still non-toxic, which confirms the guess of the proprietress, someone took advantage of the chaos to tamper with these biscuits.Furthermore, the police recalled the biscuits bought by the citizens from the proprietress the day before the incident, and the test results still showed that the biscuits were non-toxic.Based on this, it can be judged that the time when the murderer poisoned was the day of the crime, that is, August [-]th when three fresh lives were taken away.

The victim’s insurance status also came to fruition soon. Neither of the two elderly people had purchased any insurance; Cai Zhihao’s child participated in the medical insurance recommended by the school; Xu Haibo and Zhang Lu only enjoyed the additional medical insurance provided by the company; as for Wu Zhiyong, he had He bought sickness insurance, but the claim was completed when he had a stroke ten years ago. Since then, he could not continue to buy sickness insurance because of his physical condition.But ten years ago, he bought a 20-year accident insurance, and the beneficiary was his wife, Li Fang.
