Chapter 133 Three-course murder method

In terms of eating habits, the differences between north and south have always been relatively large.

The plates in front of northerners are used to place vegetables. Bones, fish bones, etc. are placed directly on the dining table or on napkins.The bowl is specially used for drinking soup.

In areas close to the north-south boundary, the food plate will also be divided into two parts for use, one half for vegetables and the other half for food scraps.

The food dishes in front of southerners are bone dishes, specially used to place bones, fish bones and other food residues.Bowls are used to hold vegetables.

If you are dining in a high-end hotel, the restaurant will prepare two plates for the guests, one large and one small. Generally, the small plate is used as a dinner plate to hold vegetables, and the large plate is used as a bone plate to put food residues.

Traditional Beijing cuisine does not produce much food residue, so there is not much food residue left in the bone dishes of diners.

He Jiahui looked at the deceased's dinner plate in the photo, and a possibility emerged in his mind.

Then He Jiahui found another photo. It was a photo taken by the forensic examiner of the entire dining table before the test. It showed very clearly what dishes were on it.

"Sir Cheng, I want to ask again the witnesses who were eating at the same table." He Jiahui said to Cheng Feng.

"Did you find a new clue?" Cheng Feng asked.

"It's not certain yet. I need to ask the witnesses to know whether the direction I guessed is correct." He Jiahui said.

"Okay, I'll call the witnesses over." Cheng Feng nodded.

He Jiahui said: "Let's start with Xiao Jiaming first."

Xiao Jiaming was brought over again, and He Jiahui said directly: "Mr. Xiao, we have to ask a few supplementary questions. I think you have a richer menu today, many of which are Beijing specialties. The person who ordered the dishes He must be very discerning, may I ask who ordered this table of dishes today?"

"We should all participate in ordering! There is a small stir-fried yellow beef dish, which I ordered." Xiao Jiaming answered.

"That means everyone ordered one or two dishes?" He Jiahui asked next.

"Not everyone has ordered. Some people looked at the menu and felt that there was nothing they liked, or maybe the ones they liked had already been ordered by others, so they didn't order anymore." Cai Jiaming replied.

He Jiahui then asked: "Did you start ordering again after everyone gathered?"

Cai Jiaming thought for a while, then shook his head: "No, when I came, Du Qiusheng and Zhang Baiqiang had already arrived, and then they gave me the menu and asked me to order. At that time, there were several check marks on the menu. It should be the dish they ordered before.”

"Manager, please bring over the menu for this table." He Jiahui turned to the manager and said.

The manager quickly found the menu, and He Jiahui handed the menu to Cai Jiaming and said, "Mr. Cai, please mark which dish you ordered."

"Okay. I ordered this stir-fried yellow beef dish, and I also ordered this lotus seed soup." Cai Jiaming answered.

He Jiahui took a note and took a note, then asked: "Mr. Cai, do you still remember where you were sitting?"

"Remember, when I was sitting inside, my girlfriend was on my left, and Ouyang Junxiong was on my right. Next to Ouyang were Zhang Baiqiang, Zhang Baiqiang's girlfriend, Du Qiusheng, Liu Zhuoyang, and Liu Zhuoyang's girlfriends." Cai Jiaming answered. .

He Jiahui marked the seats of eight people in the book, and then asked: "In other words, Du Qiusheng and Liu Zhuoyang are closest to the aisle, and the deceased is sitting inside."

"Yes." Cai Jiaming nodded.

He Jiahui continued to ask: "Mr. Cai, you and the deceased have been old friends for more than ten years. You should have a certain understanding of the deceased's living habits, right?"

Cai Jiaming nodded: "We know each other relatively well. The five of us usually talk about everything, and there are almost no secrets between us."

"Is the deceased allergic to anything? For example, peanuts?" He Jiahui then asked.

"Sir, how did you know that Ouyang Junxiong is allergic to peanuts?" Cai Jiaming asked in surprise.

"In other words, the deceased could not eat peanuts and peanut products?" He Jiahui continued to ask.

"Of course. If you are allergic, how can you eat peanuts? It may be life-threatening. He will also pay attention when eating." Cai Jiaming nodded and replied.

He Jiahui narrowed his eyes slightly, and Cai Jiaming's confession confirmed what he was thinking.

Then He Jiahui said: "Mr. Cai, I have finished asking all my questions. Thank you for your cooperation. Please keep these questions I just asked confidential and do not tell other people."

"Okay, I won't tell anyone else." Cai Jiaming agreed.

Cai Jiaming was taken away, and Cheng Feng asked: "Who should I ask next?"

"Cai Jiaming said that he was the third one to arrive. When he came, he asked Du Qiusheng and Zhang Baiqiang. They had already arrived. Let's ask Zhang Baiqiang first!" He Jiahui said.

Zhang Baiqiang was called over, and He Jiahui still asked about ordering.

"When I came, Du Qiusheng was already here. He gave me the menu and asked me to order. I saw that there were already several dishes on the menu with fancy marks on the back. Du Qiusheng should have ordered them." Zhang Baiqiang asked. .

He Jiahui took the menu again and asked, "Mr. Zhang, which dish did you order on this menu?"

Zhang Baiqiang told He Jiahui what he ordered. He Jiahui looked at the remaining dishes on the menu.

Then He Jiahui asked where everyone was sitting, which was consistent with Cai Jiaming's description.Later, He Jiahui asked the deceased again whether he was allergic to peanuts, and got the same answer.

Immediately afterwards, He Jiahui asked Liu Zhuoyang again.

"My girlfriend and I were the last to come. When I arrived, everyone else had already sat down. They gave me the menu and asked me to order. I looked at it and saw that they had already ordered many dishes, so I didn't Just order it and ask the waiter to serve it directly." Liu Zhuoyang said.

"Then you sat outside near the passage because you were the last to arrive?" He Jiahui asked.

"There were only two empty seats left, so my girlfriend and I sat down directly." Liu Zhuoyang replied.

He Jiahui asked the deceased about his peanut allergy again, and Liu Zhuoyang also gave the same answer.

So far, among the four friends of the deceased, three of them have finished interrogating, and only Du Qiusheng, who was invited this time, has not been interrogated yet.He Jiahui did not ask Du Qiusheng immediately, but called Gao An over, pointed to the photo of the dining table on the digital camera, and asked: "Sir Gao, is the location where cyanide was found on the back of the turntable under these dishes? "

"Let me take a look at the record." Gao An took out the forensic record and took a look at it, then nodded: "Yes, it is at this location, Sir He, how did you know!"

"Because I have cracked the murderer's method!" He Jiahui took a deep breath and said to Cheng Feng next to him: "Sir Cheng, call Du Qiusheng here, and make preparations to arrest him!"

"Arrest people? You mean to arrest Du Qiusheng?" Cheng Feng asked.

He Jiahui nodded: "Yes, Du Qiusheng is the murderer!"

……

Du Qiusheng was called over and was questioned by the police.

"Mr. Du, according to your friend's account, you were the first to come to today's dinner party?" He Jiahui asked.

"I treat guests, of course I have to come first, I can't let the guests wait for me!" Du Qiusheng replied.

"You ordered several dishes before anyone else came?" He Jiahui asked again.

"The waiter brought the menu over, and I ordered a few dishes, all of which are specialties here. And I was worried that I needed to make a reservation for the roast duck, so I ordered one first." Du Qiusheng replied.

"The Beijing-style fried belly, old Beijing mixed eggplant, and Qianlong cabbage, are you ordering that too?" He Jiahui asked.

"I saw on the menu that these three dishes are the specialties of this restaurant. When you go out to eat, you naturally want to taste the specialties." Du Qiusheng asked.

"You also used these three dishes to poison the deceased, right?" He Jiahui asked coldly.

Du Qiusheng was startled, and then he forced himself to calm down and said, "Sir, I don't understand what you are talking about."

He Jiahui had already guessed that Du Qiusheng would not plead guilty, so he explained: "The murderer put cyanide on the back of the turntable, and then the deceased touched it.

Later, when the deceased was eating roast duck, he took the biscuit with his hand. The biscuit was stained with cyanide on the deceased's hand, causing the deceased to be poisoned to death.This is the method of committing the crime that we deduced based on forensic examination.

But there is a problem. The area on the back of the turntable where cyanide is stained is only three centimeters by two centimeters. The deceased's hand needs to just touch this small area to be stained with cyanide.

So I have been thinking, how did the murderer let the deceased happen to touch such a small area stained with cyanide?It wasn't until I saw the deceased's dinner plate that I understood everything.

There was no trace of sesame sauce on the deceased's dinner plate, but there were three dishes on the table that contained sesame sauce. One dish was Beijing's special fried tripe, which needs to be eaten with condiments. This condiment contains sesame sauce, and the other two dishes were old Beijing dishes. Mixed with eggplant and Qianlong cabbage, it also contains sesame paste.

Sesame sauce is easy to stain on the plate. As long as the deceased puts the sesame sauce-stained dishes on the dinner plate, then the sesame sauce will definitely be stained on the dinner plate.But there was no trace of sesame paste on the deceased's dinner plate, which meant that the deceased did not eat these two dishes.

The fried tripe, mixed eggplant and Qianlong cabbage are all specialties of this restaurant. As you said, you must try the specialties when you go out to eat. Even if you don’t like them, you will try them a little!

But the deceased didn't eat the special dishes at all. The explanation I can think of is that the deceased didn't want to eat these three dishes, but he couldn't eat them at all!
It is understandable that some people are not used to eating fried belly, which is an internal organ. However, eggplant and cabbage are the most common vegetables, so no one should avoid them, right?Even if the deceased didn't eat anything to make his belly full, then it would be okay to eat a few bites of eggplant and cabbage, right?
So I speculate that the problem is not with the fried tripe or eggplant and cabbage, but with the auxiliary ingredients of these two dishes, which is sesame sauce. Both dishes use sesame sauce.

At first, I thought it was because the deceased did not eat sesame paste, but then I suddenly thought that this was not a problem with sesame paste, but a problem with peanuts. The deceased should be allergic to peanuts.

When I dined downstairs before, the waiter asked me if I was allergic to peanuts, because the Qianlong cabbage used was Erba sauce flown from Beijing, and Beijing's Erba sauce is made from sesame paste and peanut butter.

If the deceased was allergic to peanuts, then he could not eat Erbajiang, nor could he eat the three dishes of fried tripe, mixed eggplant and Qianlong cabbage.So I asked your friend and confirmed that the deceased was indeed allergic to peanuts.

I checked the photos of the dining table again and found that the three dishes of fried tripe, old Beijing eggplant and Qianlong cabbage were placed together.I asked the forensics again, and the area where cyanide was found on the back of the turntable was exactly under the three dishes.

Obviously, the murderer used these three dishes to complete the poisoning.He smeared cyanide on the back of the turntable corresponding to the two dishes, and then while eating, he turned the turntable and pointed the three dishes at the deceased.

Since the deceased was allergic to peanuts, he obviously could not eat these three dishes. When he found that he could not eat the three dishes in front of him, he could only turn the turntable away. Since the turntable was already full of dishes, he could only Put your hand under the turntable and turn the turntable.

This makes it easy for him to get cyanide on his hands.During the meal, the murderer could perform this behavior multiple times, placing three dishes containing peanut butter in front of the deceased, and the deceased would then take away the three dishes.

Even though the area stained with cyanide is only three centimeters by two centimeters, if it is repeated several times, the deceased's hands will definitely be stained with cyanide! "

"That's it!" Cheng Feng nodded with sudden realization, and looked at He Jiahui with a little more admiration in his eyes.

However, Du Qiusheng retorted: "Then why do you say I am the murderer? I am not the only one who knows that Ouyang is allergic to peanuts! Everyone knows it."

"I asked in detail just now that no one else ordered the three dishes of Beijing fried tripe, old Beijing mixed eggplant and Qianlong cabbage." He Jiahui said.

"Even if I ordered these three dishes, it doesn't prove that I was the one who poisoned them. These three dishes I ordered are all specialties of Beijing. Many people who eat here will order them. Ordering special dishes is It's very normal. If you don't believe me, go look at the tables around you!" Du Qiusheng continued to defend.

"But it is not normal for these three dishes to be placed together. You have ordered so many dishes, why are these three dishes containing Erba sauce placed together?" He Jiahui said.

"It's none of my business if the waiter puts it like this when serving food!" Du Qiusheng snorted coldly.

He Jiahui said: "I asked you where to sit, and you sat near the aisle, which means that the waiter will stand next to you when serving food.

At this time, you only need to turn the turntable to a specific position to guide the waiter to place the dishes where you need.

For example, if you see the waiter serving a plate of Qianlong cabbage, and you turn the dish of Old Beijing mixed eggplant to the waiter, the waiter will naturally place the Qianlong cabbage next to the Old Beijing mixed eggplant.

Of all the people here, you are the only one who can do this. The others are too far away from the waiter who is serving the food, and they may not even be able to see what dish the waiter is holding! "

"In addition to me, Liu Zhuoyang is also sitting near the aisle! He may also see the dishes brought by the waiter!" Du Qiusheng continued to defend.

"But Liu Zhuoyang came last, and he didn't order anything. He didn't know that three of the dishes at today's dinner contained peanut butter that the deceased couldn't eat! So it's impossible for him to design this murder method!"

He Jiahui paused for a moment, then continued: "You chose this restaurant, you ordered the three dishes containing sesame sauce, and you were the first to arrive, and you deliberately chose a location close to the passage. Among all people, Only you have the ability to carry out this murderous method, so the murderer must be you!"
