Looking at Zhang Sanmei's innocent look, it felt like that was really the case.
However, the potassium cyanide detected in the chocolate was the same as the potassium cyanide in Yuan Yang's stomach, which shows that Yuan Yang was indeed poisoned by potassium cyanide, which is understandable.
Considering the results of the previous forensic test, Gu Chen directly brought the faxed test report to Zhang Sanmei and said:
"This is the test result we got from the Technical Section 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 to Yuan Yang last night.
"
"Wha...what?" Zhang Sanmei laughed twice and said lightly: "How is that possible? I just wanted to apologize to Yuan Yang. I bought a box of chocolates on the way to the dinner party. Why did it contain potassium cyanide?
"
"I have to ask you, you bought the chocolate." Lu Weiwei said.
"Comrade police." Zhang Sanmei looked at the three of them and felt a little incredible. 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 am firmly opposed to it."
"It's impossible that I bought a box of chocolates and toxic substances were detected in it. I still have to bear the burden. Does that mean the chocolate seller is not guilty?"
"What's more, I don't even know what potassium cyanide is. How could I get this potassium cyanide onto chocolate in such a short period of time? It doesn't make sense."
After hearing Zhang Sanmei's self-defense, it seemed exactly like that, Gu Chen frowned and said nothing.
After listening to this, Officer Wang and Lu Weiwei also had some doubts.
Indeed, if, as Zhang Sanmei said, she just bought a box of chocolates on the way to the dinner party, then there would indeed be no way to inject potassium cyanide into the chocolates in a very short period of time.
But the question now is whether Zhang Sanmei had tampered with the box of chocolates between the time she bought the chocolates and when she arrived at the party. This is the key to the case.
After Gu Chen quietly communicated with Officer Wang and Lu Weiwei, the three decided to go to the dispatch room and let Zhang Sanmei stay in the interrogation room temporarily.
Scheduling room.
Several police officers are obtaining the video of Zhang Sanmei and Yuan Yang's dinner party at Gu Chen's request.
"The dinner venue is Juxianzhuang, right?" asked a first-class police superintendent.
"That's right, the time was last night, about... around seven o'clock." Based on the previous oral statements by Yuan Xiaomei and Zhang Sanmei, Gu Chen roughly locked the time at this time.
The first-level superintendent in the dispatch room was also very skilled in operating techniques and quickly found the surveillance video of the road outside Juxianzhuang.
Based on the photo of Zhang Sanmei provided by Gu Chen, he accurately found the relevant video, extracted it directly and said, "See if it's this person?"
"That's right, it's her. Senior 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 of the dispatch center.
In an instant, the video of Zhang Sanmei appearing from the right side of the road is clearly visible.
Gu Chen squinted his eyes and used his expert observation skills to carefully examine the chocolate in Zhang Sanmei's hand.
At this moment, the chocolate packaging box can still be clearly seen, 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 in Yuan Yang's house.
"So it seems that this box of chocolates was sealed and packaged with transparent film? And Yuan Yang didn't open it until he got home?" Gu Chen looked at Officer Wang and Lu Weiwei beside him.
The two of them seemed to have this consideration as well...
Lu Weiwei said: "Is it the chocolate shop that poisoned it?"
"Brother, can you show us the surveillance video of Zhang Sanmei before she arrived at the dinner place?" Gu Chen was polite again, already thinking about what happened between the chocolate shop and the dinner place.
As a member of the criminal investigation team, all clues must not be missed at all.
Although we were able to obtain the fact that potassium cyanide was contained in chocolate from the Technical Section of the Municipal Bureau, everyone seems to have many doubts about whether Zhang Sanmei was poisoned.
The first-level superintendent agreed readily and immediately agreed: "This is very simple. I just need to link the previous surveillance images based on this video to capture the path of Zhang Sanmei."
"This is best." Officer Wang said.
Soon, the first-level superintendent once again worked skillfully and reviewed all the videos of the roads Zhang Sanmei passed.
But what is surprising is that Zhang Sanmei only held the chocolate box in her hand from beginning to end, and did not perform any special processing on the chocolate.
And all the surveillance can be traced 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 or even dismantled it when she came out of the chocolate shop. How could she poison the chocolate? No.
It makes sense.”
"Is it really a store?" Lu Weiwei felt extremely scared after thinking about it, and seemed to not believe it at all.
Officer Wang said: "It's useless to say anything now. It's a fact that Yuan Yang was poisoned. Even if Zhang Sanmei wasn't poisoned, I think this store has something to do with it. Maybe the clerk tampered with her in the store."
"In other words, Zhang Sanmei has tampered with things before, and maybe she just temporarily stored the tampered chocolates in the store."
"It makes sense to wait until the day of the dinner to take out the box of chocolates containing potassium cyanide from the store."
"It feels a little unreliable." Gu Chen said.
Officer Wang was stunned for a moment: "Why?"
"Senior Brother Wang, didn't you listen to what Yuan Xiaomei said yesterday? They decided to have the dinner in Jiangnan City after get off work. This means that they didn't discuss it at all at that time. They just made a temporary decision and chose to have the dinner in Jiangnan. Shijuxianzhuang."
"If this dining location was decided on a temporary basis, how did Zhang Sanmei know about it in advance?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Officer Wang was stunned for a moment when Gu Chen asked him this question, and he couldn't answer the question for a long time.
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 check out the situation."
The three of them just did what they said. After leaving the dispatch room, they drove directly to their destination.
Near the intersection of a commercial district, Gu Chen parked his car in a parking space, and then together with Officer Wang and Lu Weiwei, they walked into the business called "Aphrodisiac Chocolate Shop".
As the door sensor was triggered, a "ding dong" sound soon sounded.
A female shop assistant wearing a brown uniform with suspenders looked at the three policemen and immediately came over with a smile on her face: "Are you three here to buy chocolate? We have many varieties here at various price points, both domestic and imported.
There are both, which one do you need?"
"We are not here to buy chocolates." Gu Chen politely refused. Instead, he 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?" When the female clerk heard this, she squinted her eyes. After looking at the photo for a while, she shook her head and said, "I wasn't here last night. Just wait. I'll call my colleague. She was on duty yesterday.
"
"It's okay." Gu Chen said calmly, "I'll wait here."
"Uh-huh." The female clerk also said "uh-huh" politely, and then went to the front desk to find her colleagues.
Taking advantage of the gap, Gu Chen quickly looked around and observed the chocolate shop.
Judging from the decoration style, it looks like a high-end store, and from the clerk's explanation, Gu Chen can probably understand from this information that this is a specialty store specializing in selling chocolate foods of various prices.
But these are not the main points that Gu Chen wants to pay attention to. The main point is that Gu Chen discovered that there are cameras in the store that can capture every corner of the store, and then he smiled with satisfaction.
"Hello, comrade police." The female clerk just called another tall and thin female colleague over, smiled and said, "This is the colleague on duty last night. 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 came to your store to buy chocolates around 6:30 last night. Do you have any impressions?"
"Her?" The tall and thin female clerk also scratched the back of her head. After recalling for a few seconds, she said, "I remember that she came to the store yesterday and bought a box of imported branded chocolates."
"Huh?" Lu Weiwei was a little confused and asked: "What the hell is OEM?"
"It's a foreign brand, but it's actually produced by a domestic manufacturer, but the packaging is all in English, making it look like imported chocolate," the female clerk said.
I was afraid that Lu Weiwei didn't understand very well, so another clerk also smiled and said: "Actually, many of our customers here will choose this product if they want to give gifts. Some of them are imported chocolates, and the price may be a bit expensive. Some customers are reluctant to part with them, so we
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 imported chocolate, and it is more prestigious when given away, so it is also the main product in our store."
"What kind is it? Can you show it to me?" Gu Chen said.
"Okay." The female clerk nodded, walked directly to the shelf, took out a box of heart-shaped chocolates, and handed it into Gu Chen's hands: "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 transparent film and sealed at all angles. This made Gu Chen even more suspicious.
After seeing Gu Chen's thoughts, Officer Wang quickly asked: "Are the chocolates you sell here sealed?"
"Isn't it...isn't it?" The female clerk also felt confused and asked Officer Wang: "Comrade police, do you want to buy it in bulk? We have cheap ones in bulk, just the ones in the frame at the door, sold by weight."
"That's not what I meant. I mean, are all your types of chocolate sealed?" Officer Wang asked again.
The two clerks looked at each other and nodded.
"I understand." Officer Wang put his hands on his hips, then pointed at the surveillance camera and said, "Can your surveillance camera retrieve for me the video of the female customer buying chocolate yesterday?"
"Are you going to investigate a case?" The three of them also look like they have a lot of backgrounds, especially Officer Wang, who feels like a big leader, while Gu Chen and Lu Weiwei are more like graphic models.
Therefore, the two female shop assistants were also curious and wanted to buy it.
Officer Wang nodded: "Yes, it is a murder case, and the suspect is this woman, so please cooperate."
"Homicide?" When the two women heard about this situation, they were instantly frightened.
After being stunned for a few seconds, one of the clerks finally said: "I understand, come with me, I'll show it to you right now."
He also led Gu Chen, 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 and various documents surrounding it.
It was probably used as an office space for the store's accounting.
After some clumsy operations on the computer, the female clerk finally found the video of Zhang Sanmei coming to shop yesterday.
So he stepped aside and said, "Comrade police, look to see if it's her?"
"That's right." Gu Chen sat down on his seat and began to watch the video of Zhang Sanmei's activities in the store over and over again.
But what Gu Chen didn't expect was that it seemed to only take Zhang Sanmei a very short time from entering the store to completing the purchase.
This chapter is not over yet, please click on the next page to continue reading! 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 this time in the store, there was no time to do anything with the chocolate.
Based on the video footage he had previously observed in the dispatch room, Gu Chen found that after Zhang Sanmei left the chocolate shop, the surveillance footage on the road completely matched the time.
In this way, it seems that Zhang Sanmei had 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 female clerk: "Has anyone had stomach upset or physical discomfort after eating private-label chocolates like yours?"
"Haha, Comrade Police, you are really good at joking." The female clerk was a little puzzled, but she still controlled her emotions and said: "Our chocolate is just a snack, and you know the ingredients of chocolate. How could you have the symptoms you mentioned?
?”
"And we don't sell expired chocolates here. They are all produced recently and are of high quality and quantity. There is no such thing as what you said."
"I see." Gu Chen was puzzled, holding a box of chocolates in his hand and asked: "As for this woman just now, apart from yesterday, has she ever been to your store at any other time?"
"Well... I don't remember it. Maybe she hasn't been here before, because she didn't even get a membership card. 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, just like before. Thank you for your cooperation."
…
…
After repeated confirmations in the store, the three returned to the police car.
Officer Wang looked forward blankly and said with some frustration: "This doesn't make sense. Forensic doctor Liu did detect that the chocolate contained potassium cyanide."
"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?"
"You're right, let's take this box of chocolates to Dr. Liu for forensic testing and we'll find out!" Lu Weiwei opened the chocolates, took one out, opened the wrapping paper, put it to the tip of her nose and sniffed, ready to put it in her mouth.
Look.
Officer Wang was so frightened that he quickly stopped him: "Lu Weiwei, do you want to die? If there is potassium cyanide in this, wouldn't you be doomed?"
"It's not that exaggerated, right?" Lu Weiwei didn't believe it, and said, "Didn't you listen to what the people in the store said? A lot of this kind of chocolate is sold every day. If it is poisonous, wouldn't this store be destroyed? They still have
Can it continue to operate? Obviously not?"
"But they are still operating well, and no one has reported them for selling poisonous chocolate?"
"Is it a random event?" Officer Wang's mind became more and more confused as he thought about it, and he was confused and said: "Maybe one of the boxes of chocolates happened to contain potassium cyanide, and Zhang Sanmei happened to buy it."
"Then, she gave it to Yuan Yang, who had had a quarrel with her, and Yuan Yang was poisoned and died directly after eating it."
"That's not right." 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 this wouldn't be the case? What kind of situation would it be?"
"Maybe the poisoning time was not the time to buy chocolate, or maybe it was not the time of the party, but after Yuan Yang returned home, someone poisoned the chocolate."
After hearing what Gu Chen said, Lu Weiwei and Officer Wang were stunned.
The two of them looked at each other dumbfounded, and then at Gu Chen, feeling that there seemed to be some truth to this.
"Junior Brother Gu." Lu Weiwei was thoughtful and asked him quickly: "You mean, after Yuan Yang got drunk, he was poisoned with chocolate when he returned home, and then framed the blame on Zhang Sanmei?"
Gu Chen nodded: "It's possible."
"Oh my God!" Lu Weiwei couldn't believe it. Her eyes widened and she said, "According to what Yuan Xiaomei said before, she left after sending her sister Yuan Yang home."
"If we follow the explanation of taking care of our junior brother, wouldn't this Yuan Xiaomei be the most suspicious?"
After thinking about it, Lu Weiwei shook her head instantly and said, "That's not right. Yuan Xiaomei is Yuan Yang's sister. There is no reason for her to harm her sister. This does not fit the motive of the murder."
"Everything is possible." While driving, Gu Chen looked up at Lu Weiwei in the rearview mirror and said, "We can call the surveillance cameras near Yuan Yang's house. I have noticed it before."
"Let's see if anyone else besides 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, I think the time of poisoning was right after Yuan Yang returned home."
