It's about four o'clock in the afternoon.

Xia Momo processed the simulation animation, from the window being smashed by a brick, to the incendiary bottle being thrown in, and burning in a closet full of clothes without a glass door. It only takes five to six minutes to engulf the bed in the master bedroom.

Xu Dayuan heard the news and watched the animation again.

Then I watched several surveillance footage from the surrounding area when the fire broke out on June 29.

Comparing the time on the monitor, you can see a hint of smoke from 23:17 on the monitor to 23:22 when flames continue to fly out of the window. It is indeed only five minutes.

The time when Dong Chengwen went out was at 23:03, and the time when he drove back was at 23:22. The car didn't even turn off. He got out of the car and rushed into the villa. Within five minutes, he carried Dong Xiaomi and Fang Hua downstairs.

, onlookers began to gather.

Of course, Fang Hua was still on fire when he was taken down.

23:27 The firefighters took the person from the door. Dong Chengwen also collapsed on the ground, seemingly crying and shaking constantly. Two ambulances pulled the three people away. Dong Xiaomi and Fang Hua were in the first one.

In the car, Dong Chengwen was in the car behind.

It was not until 23:40 that the police car arrived at the scene, allowing all onlookers to evacuate and control the order of the scene. At this time, the fire was basically under control. At 00:28, the fire brigade people evacuated, and all the people watching behind left. Only the people from the Jingkou branch were there.

Protect the scene.

"I didn't expect that only one Molotov cocktail could cause such a fire. According to the judgment of the Jingkou branch, the compound aromatic hydrocarbons collected in the room is correct."

Liu Yongxin nodded.

"A 750ml wine bottle filled with gasoline is powerful enough to be ignited and thrown in. The laboratory found glass fragments on the bricks, which can prove that the bricks were used to smash glass windows."

Xu Dayuan opened his phone, found a few pictures, and handed them to Zhou Ning and Liu Yongxin to see.

“We just asked the fire brigade of Jingkou District, and they gave us some photos when they entered the scene, which also confirmed our judgment. When glass windows are broken in a fire, they usually break outward or on the spot, and will not splash indoors.

At a distance of more than two meters, even if there is any, it is just debris. When the temperature reaches a certain level, these will have melted long ago."

Xia Momo came over.

"What about the nanny? Have you found her?"

"Nothing was found. The Jingkou Branch has not investigated this point. However, according to neighbors, Dong Chengwen's family used to have a nanny who had worked there for many years. She was a woman about forty years old and had a slightly plump Yuntai accent.

While going back and forth to pick up the children, they heard the nanny speaking English, and her pronunciation was very standard. We need to check the person's appearance from the surveillance cameras before further investigation can be carried out."

Zhou Ning was not surprised. After all, in Shanghai, all the nannies are international students, and the salary is quite high. They are educated and can tutor children, and can also help the family as a nutritionist. Dong Chengwen's family is not short of money.

At this moment, Xu Dayuan's phone rang. The caller was Tao Zhenshan. He said a few words and hung up.

"At 13:22 on June 29, Dong Chengwen went to the Black Swan Cake Shop to pick up the cake, which was ordered by his assistant Yu Xiaoou four days ago. He also specifically asked not to put mango and mango jam on it because a child was allergic to mango.

, they have records of this.

Oh, the clerk also said that when Dong Chengwen passed by, he was holding the flowers picked up from next door. Of course, the flowers were also ordered by Yu Xiaoou, and he seemed to be in a hurry. However, the parking space in front of their store was tight, so they had to pull over temporarily, and there were still some flowers in the car.

Someone was honking the horn, but they were very polite."

Liu Yongxin blinked.

"You are attentive enough. I don't even know what my wife is allergic to. I feel ashamed. It seems that he attaches great importance to this anniversary."

Xu Dayuan nodded.

At this moment, the door was pushed open, and Da Zhao hurriedly walked in, holding a laboratory test sheet in his hand. He ran to Zhou Ning and handed the report to Zhou Ning. His little eyes widened, and he obviously found something special.

Content.

"Some residue was extracted from the cake box that Zhou Xiaozhou found. After testing, it was found that it contained chocolate, cream, strawberry and other ingredients. But there is another thing, you can't guess what it is?"

Xu Dayuan raised his leg, kicked Da Zhao on the back, glared at him and said:

"It's so urgent here, do you still have the heart to play guessing games? What's in Zhou Xiaozhou's house?"

Zhou Ning turned over the report and was shocked.

"Diazepam is the ingredient that stabilizes it."

"Sleeping pills?"

Liu Yongxin came over, took a look at the content on the report, and then looked at the photos taken by Zhou Ning on the spot.

"The content is so high. It seems that it was injected into the cake from the side. The surface is covered with cream decoration. It is easy to find if there is a hole. I think it should be the diazepam injection injected from the side, and the amount is not small. It is very

I was in a hurry so there was a lot of residue left on the cake tray.”

Zhou Ning agrees with this analysis.

"The dosage of diazepam for children should not exceed 10ml at most. Adults will be poisoned if it exceeds 25ml. It can cause respiratory depression and cause respiratory arrest. This content can be found on the cake tray, so the amount invested in the cake will be very large."

"This thing is very bitter, won't you notice something strange when you eat it in your mouth?"

Zhou Ning shook his head.

"Chocolate cakes made with natural cocoa butter generally have a bitter taste, and the bitter taste of the medicine will be masked."

Xu Dayuan rubbed his chin. These discoveries had changed the nature of the case.

"To clarify, at noon on June 29, Dong Chengwen went to get flowers and cakes. Obviously they were not eaten at noon. Fang Hua and Dong Xiaomi were anesthetized after eating cakes in the evening, and their consciousness was not very clear, so the window

They were smashed and even had Molotov cocktails thrown into them, but they didn't react.

It seems that we have to wait for the results of Liu Yufei's investigation. All the evidence provided in the file returned from the Jingkou Branch needs to be re-confirmed. Xiao Zeng arranged for someone to go to Shanhai Xiaozhu in Jingkou District in a short while to transfer Dong Chengwen.

Visit all the villas around your home.

There are two main parts of the investigation. One is to ask the nannies of the surrounding neighbors who know the deceased’s nanny and their contact information. The other is whether Dong Chengwen was taken away by the police or by an ambulance after rescuing the person.

?”

Zhou Ning glanced at the file, which recorded that Dong Chengwen was taken to the hospital.

However, according to what He Shancun said, the hospital sent Fang Hua and her daughter but did not admit Dong Chengwen. When he woke up, he found that he was in the hospital and had no memory of the period from the time he saved the person to the time he woke up.

It is true that there are some discrepancies in the file, but there is still another problem. Zhou Ning called Xu Dayuan to stop.

"Xu Da, there is no mention of mobile phones in the file. Neither the mobile phones of the deceased Fang Hua nor Dong Chengwen were found at the scene, and Dong Chengwen's car has not yet been delivered."

Xu Dayuan nodded.

"I know, they said they couldn't find the phone. After a while, I asked Zhenshan to retrieve the call records. Before coming to your place, I urged Xu Kejiang again. He said that the tow truck was on the road, but it couldn't go through the tunnel and needed to go from Huanwan

Come at the high speed, but according to the time he said, the car should be here."

Xiaoqu raised his hand. Although he usually spoke little, he still took the initiative to speak when it came to his professional aspects.

"Don't raise your hands. If you have something to say, just say it."

Xu Dayuan's words made Xiaoqu take a step forward. He pointed at the computer and said.

"Can you give me your mobile phone number first? I can use the mobile phone number to first check the various social accounts they have registered, such as chat software such as QQ, crack the password first, export the chat content, and even transfer the

You can also find files, and of course shopping records, on platforms like Taobao.”

Xu Dayuan smiled, walked up to Xiaoqu, and patted him on the shoulder.

"I have the number. I was thinking of going to the people in the Information Department just now, but it seems that there is no need. You said these things, it would take them too much time to crack it."

Xiao Qu nodded.

"It's very troublesome. I'll try my best to work overtime tonight and try to complete the crack tomorrow."

"Old Liu, it seems that I want to treat you to a good meal. Xiaoqu, please take note of your phone number. Okay, no more nonsense. I will go and do my work first. We will discuss everything at the project meeting tomorrow."

Xu Dayuan left his phone number and left with his people. Da Zhao blinked and looked at Xiao Qu.

"Are you stupid? Let the people from the information department do it. It doesn't matter if they can't do it well. You can't just leave all the work in our laboratory, right?"

Xiaoqu smiled and shook his head.

"It's actually not too troublesome, but you didn't find any burned mobile phone parts at the scene?"

Da Zhao waved his hand, grabbed a bottle of mineral water, and drank it all.

"Whatever we were looking for, the scene was sifted through. We found that these things were either stuck under the floor or splashed into the corners. It seemed like a cake box was on the surface. In fact, it is more difficult to solve a second case like this."

Liu Yongxin nodded on the side, more agreeing with Da Zhao's words.

"It's difficult to make rice with uncooked rice. According to what you said, although the investigation in Jingkou District was carried out, their capabilities were limited. However, they also destroyed the scene and caused a lot of trouble for the follow-up investigation. However, when you went to the detention center, Dong

Chengwen didn’t say anything about the cake?”

Zhou Ning shook his head, sighed and looked out the window.

"I have a feeling that this guy named Dong is not telling the truth."

Da Zhao rolled his eyes, stretched out his fingers, and kept pulling at them and said:

"I'm not a conspiracy theory. His position and identity determine his lifestyle. He has to hide something. He has to pretend to be a good husband and father in front of us. Only then can you sympathize with him, work hard to detect this case, and unconsciously think about it.

To prove his innocence.

As for his net worth, I checked it online. It is conservatively estimated to be worth several million a year. As for the famous economic cases he handled, the prices are not announced. Do you think they are short of women?

It’s just that they need to create such an identity. In the eyes of customers and peers, they are a person who takes care of both career and family. This is good for his image. As for his methods, if they are not ruthless enough, none of his peers will come out.

Vocal?"
