Chapter 489

Looking at Zhang Sanmei's innocent face, I feel like that.

However, the potassium cyanide detected from the chocolate was the same as that in Yuan Yang's stomach, which showed that Yuan Yang was indeed poisoned by potassium cyanide, which is beyond reproach.

Considering the results of the previous forensic examination, Gu Chen directly took the faxed test report to Zhang Sanmei and said:

"this is the test we received from the technical department of the Municipal Bureau. It shows that the chocolate containing potassium cyanide was extracted from Yuan Yang's stomach, and this kind of chocolate is exactly the box you gave to Yuan Yang last night."

"Why What? " Zhang Sanmei laughed two times and said faintly: "how can it be? I just want to apologize to Yuan Yang. On the way to dinner, I bought a box of chocolate by the way. Why does it contain potassium cyanide? "

"I'll ask you. You bought the chocolate." She said.

"Comrade police." Zhang Sanmei looked at the three people and felt a little incredible. The whole person also explained: "if you want to say that Yuan Yang was poisoned by chocolate, and there are test results, then I have nothing to say."

"But if you want to say that I am the one who poisoned Yuan Yang, I firmly oppose it."

"It's impossible for me to buy a box of chocolates, and the poisonous substances are detected in them. I have to carry this pot. Is the chocolate seller innocent?"

"What's more, I don't know what potassium cyanide is. How can I get this potassium cyanide on chocolate in such a short time? It doesn't make sense. "

Listening to Zhang Sanmei's self explanation, she seems to be totally like that. Gu Chen frowns and doesn't speak.

And Wang police officer and Lu Weiwei after hearing, also produced some doubts.

Indeed, if Zhang Sanmei said that she just bought a box of chocolates on the way to the dining place, she could not inject potassium cyanide into the chocolate in a very short time.

But now the question is whether Zhang Sanmei has ever tampered with this box of chocolates since she bought chocolate and came to the dinner party. This is the key to the case.

After Gu Chen whispers to police officer Wang and Lu Weiwei, they decide to go to the control room and let Zhang Sanmei stay in the interrogation room for the time being.

Control room.

According to Gu Chen's request, several police officers are getting the video of the dinner party of Zhang Sanmei and Yuan Yang.

"It's Juxian village, isn't it?" Asked a sergeant I.

Last night, probably, it was Around seven o'clock. " According to the oral statements made by Yuan Xiaomei and Zhang Sanmei before, Gu Chen probably locked the time in this period of time.

The first grade superintendent in the control room is also very skillful in operation, and soon found the monitoring video of the road around juxianzhuang.

According to the photo of Zhang Sanmei provided by Gu Chen, he found the relevant video accurately and extracted it directly: "do you want to see if it's this person?"

"Yes, it's her. Please extract the video to the big screen." Gu Chen said.

"No problem." The first grade Sergeant obeyed his orders and directly extracted the monitoring image from the computer to the large screen of the dispatching center.

In an instant, Zhang Sanmei's video from the right side of the road is clearly visible.

Gu Chen narrowed his eyes and examined the chocolate in Zhang Sanmei's hands carefully with her professional observation.

At the moment, the chocolate box can still be clearly visible, which is attached by a layer of reflective film.

this is as like as two peas on the chocolate box that you found from Yuan Yang's house.

"So this box of chocolates is sealed with transparent film? And Yuan Yang didn't open it until he got home? " Gu Chen looks at officer Wang and Lu Weiwei.

It seems that they have the same consideration

"Is it the chocolate shop that poisons it?" Lu Weiwei said

"Elder martial brother, can you show us the monitoring before Zhang Sanmei comes to the dining place?" Gu Chen is polite again. He has already begun to think about the situation from the chocolate shop to the dining place.

As a member of the criminal investigation team, all kinds of clues can not be flawed.

Although we can get the fact that potassium cyanide is contained in chocolate from the technical department of the Municipal Bureau, there seems to be a lot of doubts about whether Zhang Sanmei has poisoned this link.

The first level Sergeant agreed quite frankly, and immediately agreed: "this is very simple. As long as I link up the previous monitoring images according to this video, I can capture the path of Zhang Sanmei."

"It's best." Wang said.

Soon, the first grade police officer again skilled operation, will Zhang three sister all the road video, all check.

What is surprising is that from the beginning to the end, Zhang Sanmei only held a chocolate box in her hand, and did not appear to carry out special processing of chocolate.

And all the surveillance goes back to the chocolate shop

"That's strange." Gu Chen held her chest in both hands and said with some misgivings: "since she came out of the chocolate shop, Zhang Sanmei has never moved the packaging or even disassembled it. How could she poison the chocolate? It doesn't make sense. ""Is it really a shop?" Lu Weiwei feels very afraid of thinking carefully, and seems to have a little disbelief.

Wang said: "it's useless to say anything now. Yuan Yang's poisoning is a fact. Even if Zhang Sanmei didn't poison her, I don't think this store can get rid of the trouble. Maybe the shop assistant has done something in the shop."

"In other words, Zhang Sanmei has been tampering with before, but maybe she will temporarily deposit the chocolate in the store."

"It's a good thing to wait until the dinner day and take out the box of chocolate containing potassium cyanide from the shop."

"It doesn't feel right." Gu Chen said.

Officer Wang froze for a moment: "why?"

"Elder martial brother Wang, didn't you listen to Yuan Xiaomei yesterday? They decided to place the dinner party in Jiangnan City after work. This shows that they did not discuss it at that time. They just decided to put the meal in Juxian village, Jiangnan City. "

"If this dining place is temporarily determined, how can Zhang Sanmei know in advance?"

Also by Gu Chen such a question, officer Wang was stunned for a while, for a short time can't pick up a word.

Lu Weiwei also nodded and agreed: "what Gu Shidi said is right, but if all the problems can't be explained, there seems to be some problems in this chocolate shop. Are they responsible for it?"

"I can only go there in person." Gu Chen said.

After several seconds of thinking back and forth at the scene, officer Wang agreed: "well, let's hurry up and go to this chocolate shop to see the situation."

After leaving the control room, they drove directly to their destination.

At the intersection of a commercial block, Gu Chen parked his car in a parking space, which led him to enter the "Eros chocolate shop" with police officer Wang and Lu Weiwei.

With the trigger of the door induction, a "Ding Dong" sound soon sounded.

A female shop assistant, wearing a barista's harness uniform, looked at the three policemen and immediately came over with a smile: "are you here to buy chocolate? We have a lot of varieties here, all kinds of prices, domestic and imported. Which one do you need

"We're not here to buy chocolate." Gu Chen refused directly and kindly. Second, he took out a picture of three sisters and said, "this man once came to your store to buy chocolate last night. Do you remember that?"

"Last night?" On hearing this, the saleswoman squinted directly, looked at the picture and then shook her head and said, "I was not here last night. Wait a minute. I'll call my colleague. She was on duty yesterday."

"It doesn't matter." Gu Chen light way: "I wait here."

"Mm-hmm." The saleswoman also politely "mm-hmm" two, then went to the front desk to find colleagues.

Taking advantage of the gap, Gu Chen quickly looked around for a week to observe the chocolate shop.

From the perspective of decoration style, it is like a high-end shop. With the explanation of the shop assistant, Gu Chen can probably learn from the information that this is a specialized store specializing in selling chocolate food at various prices.

However, these are not the focus of Gu Chen's attention. The point is that Gu Chen found that there are cameras in the store, which can capture all corners of the store, which makes him smile with satisfaction.

"Hello, comrade police." Just now, the saleswoman called another tall and thin female colleague over and said with a smile, "this is the colleague on duty last night. Please ask her what you want to ask."

"Thank you." Gu Chen said politely, then took the picture of Zhang Sanmei in his hand: "this man, at about 6:30 last night, once came to your store to buy chocolate. Do you have any impression?"

"She?" The tall and thin saleswoman scratched the back of her head. After a few seconds of recollection, she said, "I remember. She came to the store yesterday and bought a box of imported chocolates

"Well?" Lu Weiwei some doubts, and asked: "what is the ghost of OEM?"

"It's made by domestic manufacturers with foreign brands, but the packaging is all in English, which makes people feel like imported chocolate." Said the saleswoman.

I'm afraid Lu Weiwei didn't understand that, so another shop assistant also said with a smile: "in fact, many customers here want to give gifts. They will first of all like this product. Some of them are imported chocolate. The price may be a little expensive, and some customers are not willing to give up. So we will recommend this kind of chocolate."

"That is to say, the packaging is imported from abroad, but actually it is produced in China. Of course, the price of this kind of gift giving chocolate is much lower than that of import, and it is also a product mainly promoted by our store because it has twice the face when it is sent out."

"What kind? Can you show it to me? " Gu Chen said.

"Yes." The saleswoman nodded, went directly to the shelf, took down a box of heart-shaped packing chocolate box, and handed it to Gu Chen's hand: "this is the kind of chocolate I mean."

Gu Chen holds it in his hand and observes repeatedly. The chocolate box is covered with a layer of transparent film, and all places are sealed. This makes Gu Chen even more suspicious.

After seeing Gu Chen's idea, officer Wang quickly asked, "are all the chocolates you sell here sealed?""Is it Isn't it? " The saleswoman also felt puzzled and asked officer Wang, "police comrade, do you want to buy bulk? We have cheap ones in bulk, but those in the door frame are sold by weight. "

"I don't mean that. I mean, are all your chocolates sealed?" Wang asked again.

The two clerks looked at each other and nodded.

"I see." Officer Wang crossed his waist, then pointed to the monitor and said, "can you get me the monitor here? Just take the chocolate purchased by this female customer yesterday."

"Are you going to investigate the case?" It also depends on the appearance of the three, especially officer Wang, who feels like a big leader, while Gu Chen and Lu Weiwei are more like plane models.

So the two saleswomen were curious and did not want them.

Officer Wang nodded: "yes, it is a homicide case, the suspect is this woman, so please cooperate with me."

"Homicide?" Two women listen to this situation, the moment is also scared silly.

After a few seconds of inaction, one of the shop assistants said, "I see. Come with me. I'll transfer it to you."

Also led Gu Chen, officer Wang and Lu Weiwei, we came to a small office together.

This is the place where the clerks work. It can only hold a desk with a computer on it, surrounded by various documents.

It's supposed to be an office space for store bookkeeping.

After a clumsy operation on the computer, the saleswoman found the video of Zhang Sanmei shopping yesterday.

So he took the initiative to get out of the way: "police comrade, do you have a look at her?"

"That's right." Gu Chen sits in his seat and starts to watch the video of Zhang Sanmei's activities in the store repeatedly.

To Gu Chen's surprise, it seems that it took only a very short time for Zhang Sanmei to enter the store and purchase.

And it was under the sales promotion explanation of the shop assistant that she chose the branded chocolate on the shelf, paid directly and left.

There was no other time for chocolate in the shop.

According to the video images observed in the control room before, Gu Chen found that after Zhang Sanmei left the chocolate shop, it was completely matched with the monitoring screen and time on the road.

In this way, it seems that Zhang Sanmei has no time to poison at all, which means that the poisoning has nothing to do with Zhang Sanmei.

Gu Chen frowned and turned to ask the salesgirl, "have you ever had a stomachache after eating this kind of OEM chocolate, or have you suffered from physical discomfort?"

"Ha ha, police comrade, you really know how to joke." The salesgirl was puzzled, but she still controlled her mood and said, "my chocolate is a snack. You know the ingredients of chocolate. How can you have the symptoms you mentioned?"

"And we don't sell expired chocolates here. They're all made recently. They guarantee both quality and quantity. There's no such situation as you said."

"I see." Gu Chen couldn't figure it out. Holding a box of chocolate in his hand, Gu Chen asked, "just now, has she ever been to your store except yesterday?"

"Well No impression. Maybe she didn't come, because she didn't even have a membership card. She should have bought it at random. " Said the saleswoman.

Lu Weiwei took the box of chocolates and said with a smile, "please help me get a box of chocolates. Just like that, thank you for your cooperation."

……

……

After repeated confirmation in the store, the three returned to the police car.

Police officer Wang looked at the front, some depressed: "this is unreasonable ah, forensic Liu that is indeed detected in the chocolate, contains potassium cyanide."

"What's more, this box of chocolate was bought by Zhang Sanmei and given to Yuan Yang. But how did she poison it? Are we wrong? "

"Do not make a mistake, take this box of chocolate to Liu forensic examination, don't know!" Lu Weiwei unwrapped the chocolate, took out a piece of unwrapping paper, put it on the tip of her nose and sniffed it, ready to be put into her mouth.

Officer Wang was scared to stop: "Lu Weiwei, are you going to die? If there's potassium cyanide in here, aren't you going to finish it? "

"No such exaggeration?" Lu Weiwei was a little incredulous and said, "didn't you listen to the people in the shop? This kind of chocolate has to be sold a lot every day. If it is poisonous, then the shop will be ruined? Can they continue to operate? Obviously not? "

"But they are still in good condition. No one reports that they sell poisonous chocolate?"

"Is it a random event?" Officer Wang's head became more and more confused. Some of the six gods had no idea: "maybe one of the boxes of chocolate just contains potassium cyanide, but it just happened to be bought by Zhang Sanmei."

"Then, he gave Yuan Yang, who had a festival with her, in a muddle headed way. As a result, Yuan Yang died of poisoning after eating it."

"No Gu Chen also denies the speculation of officer Wang, which, after all, doesn't sound very reliable.Officer Wang looked at Gu Chen and asked weakly, "you say it won't be like this? What would that be? "

"Maybe the time of poisoning is not the time to buy chocolate, or the time for a party, but Yuan Yang was poisoned in the chocolate after he went home."

Listening to Gu Chen, Lu Weiwei and police officer Wang were stunned.

Two people look at each other, and look at Gu Chen, it seems that there is a little bit of truth.

"Brother Gu." Lu Weiwei, if thoughtful, quickly asked him: "do you mean that Yuan Yang was poisoned by chocolate when he got home after he was drunk, and then put the blame on Zhang Sanmei?"

Gu Chen nodded: "possible."

"My God Lu Weiwei couldn't believe it. She glared at her eyes and said, "according to Yuan Xiaomei's words before, she left after she sent her sister Yuan Yang home."

"If according to Gu's explanation, isn't yuan Xiaomei the most suspect?"

After thinking about it, Lu Weiwei immediately shook her head and said, "no, Yuan Xiaomei is Yuan Yang's sister. She has no reason to harm her sister. This is not in line with the motive of killing."

"Everything is possible." While driving, Gu Chen looked up at Lu Weiwei in the rear-view mirror and said, "we can get the surveillance near Yuan Yang's house. I noticed that before."

"Let's see if there are any other people who have been to Yuan Yang's home after going home last night."

"If there is, it means that other people are suspected. If not, it means that Yuan Xiaomei is suspected. No matter who it is, the time of poisoning, I think it should be after Yuan Yang goes home."
