I am a super cop

Chapter 489 Poisoning Time 【Seeking Monthly Ticket】

Looking at Zhang Sanmei's innocent face, it really seemed like that.

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

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

"This is the test result we got from the Technical Department of the Municipal Bureau. It shows that chocolate containing potassium cyanide was extracted from Yuan Yang's stomach, and this chocolate is exactly the box you gave Yuan Yang last night. "

"What... what?" Zhang Sanmei laughed twice, and said lightly, "How is it possible? I just wanted to apologize to Yuan Yang. On the way to the dinner, I bought a box of chocolates. Why does it contain potassium cyanide? "

"I'm going to ask you that. You bought the chocolate." Lu Weiwei said.

"Comrade police." Zhang Sanmei looked at the three of them, feeling a little unbelievable, and she also defended herself: "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 was the one who poisoned Yuan Yang, then I firmly oppose it."

"It's impossible for me to buy a box of chocolates. Toxic substances were detected in it. I have to bear the blame. So the chocolate seller is not guilty?"

"What's more, I don't even know what that potassium cyanide is. How could I get this potassium cyanide onto chocolate in such a short period of time? It doesn't make sense."

He also listened to Zhang Sanmei's self-defense, which seemed to be exactly what happened, Gu Chen frowned and didn't speak.

After listening to Police Officer Wang and Lu Weiwei, they also had some doubts.

Indeed, if it was true what Zhang Sanmei said, she just bought a box of chocolates on the way to the dinner party, then in a very short period of time, it is indeed impossible to inject potassium cyanide into the chocolate.

But the question now is whether Zhang Sanmei has tampered with the box of chocolates between the time she bought the chocolates and when she came to the dinner party. This is the key to the case.

After Gu Chen communicated with Police Officer Wang and Lu Weiwei in a low voice, the three decided to go to the dispatch room and ask Sanmei Zhang to stay in the interrogation room temporarily.

Scheduling room.

According to Gu Chen's request, several police officers are obtaining the video of Zhang Sanmei and Yuan Yang having dinner that night.

"The place for the dinner is Juxianzhuang, isn't it?" a first-level police superintendent asked.

"That's right, the time was last night, around... around seven o'clock." Based on the previous oral statements by Yuan Xiaomei and Zhang Sanmei, Gu Chen probably locked the time at this time.

The first-level police superintendent in the dispatching room was also very skilled in operation, and soon found the surveillance video of the roads outside Juxianzhuang.

According to the photo of Zhang Sanmei provided by Gu Chen, I found the relevant video accurately, and directly extracted it: "Take a look, is it this person?"

"That's right, it's her, brother, please extract the video to the big screen." Gu Chen said.

"No problem." The first-level superintendent obeyed and directly extracted the surveillance images from the computer to the large screen in the dispatch center.

In an instant, Zhang Sanmei was clearly visible from the video that appeared on the right side of the road.

Gu Chen squinted his eyes, and carefully inspected the chocolate in Zhang Sanmei's hand using his expert observation skills.

At this moment, the chocolate packaging box is still clearly visible, and it is attached by a layer of reflective film.

This is exactly the same as the film on the chocolate box that everyone found from Yuan Yang's home.

"So it seems that this box of chocolates was sealed and packaged with a transparent film? And Yuan Yang didn't open it until he got home?" Gu Chen looked at Police Officer Wang and Lu Weiwei beside him.

The two seem to have this consideration too...

Lu Weiwei said, "Could it be the chocolate shop that poisoned you?"

"Brother, can you show us the surveillance before Sanmei Zhang came to the dinner party?" Gu Chen was polite again, and he had already started to think about the situation between the chocolate shop and the dinner party.

As a member of the criminal investigation team, there must be no mistakes in all kinds of clues.

Although they were able to get the fact that the chocolate contained potassium cyanide from the technical department of the Municipal Bureau before, everyone seemed to have a lot of doubts about whether Zhang Sanmei had been poisoned.

The first-level police superintendent agreed quite readily, and immediately agreed: "This is very simple. I only need to link the previous surveillance images based on this video, and then I can capture the path of Zhang Sanmei."

"This is the best way." Officer Wang said.

Soon, the first-level police superintendent was skilled again, and checked all the road videos of Sanmei Zhang.

What is surprising is that Zhang Sanmei only held the chocolate box from the beginning to the end, and did not perform any special processing of the chocolate.

And all the monitoring goes all the way back to the chocolate shop...

"This is very strange." Gu Chen crossed his arms and said with some doubts: "Zhang Sanmei never touched the packaging when she came out of the chocolate shop, and she never even disassembled it. How could she poison the chocolate? No Makes sense."

"Is it really a store?" Lu Weiwei felt terrified after thinking about it, and seemed to be a little bit unconvinced.

Officer Wang said: "It's useless to say anything now. Yuan Yang's poisoning is a fact. Even if Zhang Sanmei hadn't been poisoned, then I don't think this store can get away with it. Maybe the clerk tampered with it in the store."

"In other words, Zhang Sanmei has tampered with it before, and maybe she just temporarily stored the tampered chocolate in the store."

"And it makes sense to wait until the day of the dinner party to take out the box of chocolates containing potassium cyanide from the store."

"It feels a bit unreliable." Gu Chen said.

Officer Wang was stunned for a moment: "Why?"

"Senior Brother Wang, didn't you listen to Yuan Xiaomei's words yesterday? They decided on the location of the dinner party in Jiangnan City after get off work. This shows that they didn't discuss it at all at the time. City Juxianzhuang."

"If it is said that this dining place was decided temporarily, how did Sanmei Zhang know it in advance?"

This question was also asked by Gu Chen, Officer Wang was stunned for a moment, unable to answer for a while.

Lu Weiwei also nodded in agreement: "Junior Brother Gu is right, but if all the problems cannot be explained, then there seems to be something wrong with this chocolate shop. Could it be that they did it?"

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

Officer Wang thought back and forth at the scene for a few seconds before agreeing: "Okay, then let's hurry up and go to this chocolate shop to see the situation."

The three of them did what they said, and after leaving the control room, they drove directly to their destination.

Near the intersection of a commercial block, Gu Chen parked his car in a parking space, and then, together with Police Officer Wang and Lu Weiwei, walked into this business called "Eros Chocolate Shop".

Following the triggering of the door sensor, there was a "ding dong" sound soon.

A female clerk in a brown suspender uniform saw the three policemen, and immediately walked over with a smile on her face: "The three are here to buy chocolates? We have many varieties here, at various prices, domestic and imported There are both, which one do you want?"

"We're not here to buy chocolates." Gu Chen directly refused kindly, but took out a photo of Zhang Sanmei and said, "This person came to your store to buy chocolates last night, do you remember?"

"Last night?" The female clerk squinted her eyes when she heard this, looked at the photo, then shook her head and said, "I wasn't here last night, wait a minute, I'll call my colleague, she was on duty yesterday. "

"It's okay." Gu Chen said lightly, "I'll wait here."

"Yeah." The female clerk also said "hmm" politely, and then went to the front desk to find a colleague.

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

Judging from the decoration style, it looks like a high-end store. With the clerk's explanation, Gu Chen can probably understand from the information that this is a specialty store that sells chocolates at various prices.

But these are not the focus of Gu Chen's attention. The point is that Gu Chen found out that there is a camera in the store, which can capture every corner of the store, so he smiled quite satisfied.

"Hello, Comrade Police." The female clerk called another tall and thin female colleague over, smiled and said, "This is the colleague who was on duty last night. You can ask her what you want to ask."

"Thank you." Gu Chen was polite, and then took Zhang Sanmei's photo in his hand: "This person, around 06:30 last night, once came to your store to buy chocolates, do you have any impression?"

"Her?" The tall and thin female shop assistant also scratched the back of her head, and said after a few seconds of recollection: "I remember, she came to the store yesterday and bought a box of imported private-label chocolates."

"Huh?" Lu Weiwei was a little puzzled, and asked again: "What the hell is the OEM?"

"It is a foreign brand, but it is actually produced by a domestic manufacturer, but the packaging is all in English, which makes people feel that it is imported chocolate." The female shop assistant said.

Afraid that Lu Weiwei didn't really understand, another clerk also smiled and said: "Actually, many customers here will choose this product as a gift. Some are imported chocolates, and the price may be a bit expensive. Some customers are reluctant, so we just Would recommend this chocolate."

"That is to say, the packaging is imported from abroad, but it is actually produced in China. Of course, the price of this kind of chocolate for gift-giving is much lower than that of imports, and it is more face-saving when you send it out. Therefore, it is also the main product in our store."

"Which one is it? Can you show it to me?" Gu Chen said.

"Yes." The female shop assistant nodded, walked directly to the shelf, took out a heart-shaped box of chocolates, and handed it to Gu Chen: "This is the kind of chocolate I was talking about."

Gu Chen held it in his hand and observed it repeatedly. The chocolate box was covered with a layer of transparent film, and all angles were sealed, which made Gu Chen even more suspicious.

After seeing Gu Chen's thoughts, Officer Wang hurriedly asked, "Are all the chocolates you sell here sealed?"

"Isn't it... isn't it?" The female clerk was also puzzled, and asked Police Officer Wang: "Comrade police, do you want to buy in bulk? We have cheap ones in bulk. The ones in the box at the door are sold by the pound."

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

The two clerks looked at each other and nodded.

"I see." Officer Wang put his hips on his hips, then pointed to the surveillance camera and said, "Can you call me the surveillance camera on your side, just call the section where the female customer bought chocolates yesterday."

"Are you going to investigate the case?" It also seemed that the three of them had a lot of background, especially Police Officer Wang, who felt like a big leader, while Gu Chen and Lu Weiwei were more like plane models.

Therefore, the two female shop assistants were also curious about not wanting it.

Officer Wang nodded: "That's right, it's a murder case, and the suspect is this woman, so please cooperate."

"Murder case?" When the two women heard the situation, they were instantly terrified.

After being dazed for a few seconds, one of the clerks said: "I see, come with me, I'll transfer it to you."

He also led Gu Chen, Police Officer Wang and Lu Weiwei to a small office.

This is where the clerk works. There is only room for a desk with a computer on it, surrounded by various documents.

It is estimated that it is an office space used for bookkeeping in the store.

After some clumsy operations on the computer, the female shop assistant finally found the video of Zhang Sanmei shopping yesterday.

So he took the initiative to step aside and said, "Comrade policeman, can you see if it's her?"

"That's right." Gu Chen sat on the seat and began to watch the video of Zhang Sanmei's activities in the store repeatedly.

But what Gu Chen didn't expect was that it seemed that it only took Zhang Sanmei a very short time from entering the store to making a purchase.

And it was only after the clerk's promotional explanation that she chose the private label chocolate on the shelf, paid directly and left.

During the period in the store, there was no other time to tamper with chocolate.

According to Gu Chen's previous observation of the video in the dispatch room, after Zhang Sanmei left the chocolate shop, the monitoring screen and time on the road exactly matched.

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

Gu Chen frowned, turned to ask the female shop assistant: "Your private label chocolate, has anyone had a stomachache or physical discomfort after eating it?"

"Hehe, comrade policeman, you really know how to joke." The female clerk was a little puzzled, but she still controlled her emotions and said, "Our chocolate is a snack, and you know the ingredients of chocolate, so why do you have the symptoms you mentioned?" ?”

"And we don't sell expired chocolates here. They are all recently produced, and the quality and quantity are guaranteed. There is no such situation as you said."

"I see." Gu Chen was puzzled, holding a box of chocolates in his hand and asked: "This woman just now, has she been to your store at other times besides yesterday?"

"Well... I don't remember it, maybe she hasn't been here, because she didn't even get a membership card, so she probably came here randomly to buy it." The female clerk said.

Lu Weiwei took the box of chocolates, smiled and said, "Then help me get a box of chocolates, the kind just now, thank you for your cooperation."

……

……

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

Officer Wang looked forward blankly, and said with some frustration: "It doesn't make sense, forensic doctor Liu did detect potassium cyanide in the chocolate."

"And this box of chocolates was indeed bought by Zhang Sanmei as a gift to Yuan Yang, but how did she poison it? Could it be that we made a mistake?"

"That's right, take this box of chocolates to Forensic Doctor Liu for a test and you'll know!" Lu Weiwei unwrapped the chocolates, took one out of the wrapping paper, sniffed it on the tip of her nose, and was about to put it in her mouth. look.

Police officer Wang was so frightened that he quickly stopped him: "Lu Weiwei, are you dying? If there is potassium cyanide in it, wouldn't you be dying?"

"It's not so exaggerated, is it?" Lu Weiwei said in disbelief, "Didn't you listen to the people in the store? This kind of chocolate is sold in a lot every day. If it is poisonous, wouldn't the store be doomed? They still Can it continue to operate? Obviously not?"

"But they are still running well, and no one has reported them for selling poisonous chocolate?"

"Could it be a random event?" Officer Wang's mind became more and more confused, and he was a little confused: "Maybe one of the boxes of chocolates happened to contain potassium cyanide, and it happened to be bought by Zhang Sanmei."

"And then, in a daze, it was given to Yuan Yang, who had a feud with her, and Yuan Yang was directly poisoned to death after eating it."

"No." Gu Chen also denied Officer Wang's guess, after all, it didn't sound very reliable.

Officer Wang looked at Gu Chen, and asked weakly, "You said it wouldn't be like this? What kind of situation would it be?"

"Maybe the poisoning time is not the time to buy chocolates, or it may not be the time to party, but after Yuan Yang returned home, someone poisoned the chocolate."

Hearing what Gu Chen said, both Lu Weiwei and Police Officer Wang were stunned.

The two looked at each other in a daze, and then looked at Gu Chen, feeling that there seemed to be some reason.

"Junior Brother Gu." Lu Weiwei asked him thoughtfully, "You mean, after Yuan Yang got drunk, he was poisoned in chocolate when he returned home, and then blamed Sanmei Zhang?"

Gu Chen nodded: "It's possible."

"Oh my god!" Lu Weiwei couldn't believe it. She widened her eyes and said, "According to what Yuan Xiaomei said before, she left after sending her sister Yuan Yang home."

"According to the explanation of taking care of junior brother, isn't this Yuan Xiaomei the most suspicious?"

After thinking about it, Lu Weiwei shook her head instantly and said, "No, Yuan Xiaomei is Yuan Yang's younger sister. She has no reason to harm her own older sister. This doesn't fit the motive of killing her."

"Anything is possible." While driving, Gu Chen looked up at Lu Weiwei in the car's rearview mirror, and said, "We can call the surveillance cameras near Yuan Yang's house, and I noticed it before."

"See if anyone other than Yuan Xiaomei has been to Yuan Yang's house after returning 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 should be right after Yuan Yang returned home."
