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

Xia Momo processed the simulated animation, from the window being smashed by bricks, to the Molotov cocktail being put in, burning in a cloakroom full of clothes without glass doors, and it only took 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 the surrounding surveillance footage when the fire caught fire on June 29.

According to the time on the surveillance, from 23:17 the surveillance, you can see the surging smoke, to 23:22 The tongue of fire keeps flying out of the window, it is indeed only five minutes.

And the time when Dong Chengwen went out, at 23:03, he drove back at 23:22, the car did not turn off, he rushed into the villa when he got out of the car, and then in less than five minutes, Dong Xiaomi and Fang Hua were carried downstairs successively, and the onlookers began to gather.

Of course, when Fang Hua was taken down, there was still fire on his body.

23:27 The firefighters picked up the person from the door, Dong Chengwen also collapsed to the ground, seemed to be crying, trembling all over, two ambulances, pulling the three people away, Dong Xiaomi and Fang Hua in the first car, Dong Chengwen in the car behind.

It wasn't until 23:40 that the police car arrived at the scene, allowing all the onlookers to evacuate and control the order of the scene, and at this time the fire was basically controlled, and at 00:28 the people of the fire brigade were evacuated, and the onlookers behind were all gone, and only the people from the Jingkou Branch were protecting the scene.

"I didn't expect that only one incendiary bottle was needed to start such a fire, and according to the judgment of the Jingkou Branch, the judgment that compound aromatic hydrocarbons were collected in the room was correct."

Liu Yongxin nodded.

"A 750ml bottle filled with gasoline, it was enough to ignite the power of throwing it in, and the laboratory was on the brick, and found glass shards, which could prove that the bricks were used to smash glass windows."

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

"Just now we asked the fire brigade of Jingkou District, and they gave some photos when they entered the scene, and also confirmed our judgment, the glass windows in the fire were broken, generally outward or on the spot, and would not burst into the room at a distance of more than two meters, even if there were, they were all slag, and the temperature reached a certain level, and these would have melted a long time ago."

Xia Momo came over.

"What about the nanny, did you find it?"

"I didn't find it, this point was not investigated by the Jingkou Branch, but according to the neighbor's reaction, Dong Chengwen's family originally had a nanny who had worked for many years, a woman about forty years old, with a slightly chubby Yuntai accent.

When picking up the children back and forth, they also heard the nanny speak English, and the pronunciation was very standard. ”

Zhou Ning didn't have many surprises, after all, in Shanghai, there are nannies who are international students, and the salary is quite high, they have the culture to tutor children, and they can also help the family as a nutritionist, and Dong Chengwen's family is not bad for this money.

At this moment, Xu Dayuan's phone rang, and it was Tao Zhenshan who called, said a few words, and hung up the phone.

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, and specially explained not to put mango and mango jam, saying that there was a child who was allergic to mangoes, and they had a record of this.

Oh, the clerk also said that when Dong Chengwen went over, he was holding the flowers taken next door in his hand, of course, the flowers were also ordered by Yu Xiaoou, and he was in a hurry, but the parking space in front of their store was tight, so he could only pull over temporarily, and there were still people honking their horns in the car, but they were very polite. ”

Liu Yongxin blinked.

"Careful enough, I don't even know what my wife's allergies are, I'm 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 test sheet in his hand, ran to Zhou Ning and handed the report to Zhou Ning, his small eyes widened, obviously finding something special.

"On the cake box that Zhou Xiaozhou found, some residues were extracted, and after testing, it was found that there were chocolate, cream, strawberries and other ingredients in it, but there was another thing, you can't guess what it is?"

Xu Dayuan raised his legs, kicked Da Zhao's back shackles, glared at him and said:

"It's a hot fire here, do you still have the heart to have some guessing fun? What's in Zhou Xiaozhou? ”

Zhou Ning flipped through the report, and people were shocked.

"Diazepam is the ingredient of stabilization."

"Sleeping pills?"

Liu Yongxin came over, glanced 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, and the surface is full of creamy surface flowers, if it is easy to find if it is empty, I think it should be diazepam injection injected from the side, and the amount is not small, it is very hasty, so a lot of it remains on the top of the cake tray."

Zhou Ning agrees with this analysis.

"The dosage of diazepam for children should not exceed 10ml at most, and adults will be poisoned if they exceed 25ml, which can cause respiratory depression and respiratory arrest.

"This thing is very bitter, won't you find anything strange in your mouth?"

Zhou Ning shook his head.

"Chocolate cakes with natural cocoa butter generally taste bitter, and the bitterness of the drug will be masked."

Xu Dayuan rubbed his chin, these discoveries made this eucalyptus have changed its nature.

"Let's put it up, at noon on June 29, Dong Chengwen went to get flowers and cakes, obviously this was not eaten at noon, after eating cakes at night, Fang Hua and Dong Xiaomi were anesthetized, and their consciousness was not very clear, so the window was smashed, and they didn't react even when they threw Molotov cocktails.

It seems that we have to wait for the results of Liu Yufei's investigation, all the evidence provided in the file taken back from the Jingkou Branch needs to be reconfirmed, Xiao Zeng arranged for someone, and after a while, he will go to the mountains and seas in Jingkou District to visit all the villas around Dong Chengwen's house.

There are two main parts of the investigation, one is to ask the nanny of the neighbors, who knows the nanny of the deceased's family, and the contact information, and the other is that after Dong Chengwen rescued the person, was he taken away by the police or pulled away by an ambulance? ”

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's mother and daughter, but Dong Chengwen was not admitted, and when he woke up, he found that he was in the hospital, and he had no memory of the period from saving people to waking up.

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

"Xu Da, there is no mention of mobile phones in the file, the mobile phones of the deceased Fang Hua and Dong Chengwen were not found at the scene, and Dong Chengwen's car was still not delivered."

Xu Dayuan nodded.

"I know, they said they didn't find the phone, and after a while, I asked Zhenshan to retrieve the call records, before coming to you, I urged Xu Kejiang again, he said that the trailer has been on the road, but it can't go through the tunnel, and it needs to come from the Huanwan Expressway, but according to the time he said, the car should also arrive."

Xiaoqu raised his hand, although he has always said little, but when it comes to his professional aspects, he still takes the initiative to speak.

"Don't raise your hand, say something straight."

Xu Dayuan's words made Xiaoqu take a step forward, and he pointed to the computer and said.

"Can you give me my phone number first?" I can use my mobile phone number to check the various social accounts they have registered first, such as QQ and other chat software, crack the password first, export the chat content inside, and even find the transferred files, oh, of course, there are shopping records, which is a platform like Taobao. ”

Xu Dayuan smiled, leaned in front of Xiaoqu, and patted him on the shoulder.

"I have the number, I was thinking about going to the information department just now, it seems that I don't need it, you say these things, they take too much time to crack them."

Xiaoqu nodded.

"It's very troublesome, I'll work overtime tonight to finish it tomorrow."

"Lao Liu, it seems that I want to ask you to have a good time, Xiaoqu, you remember the phone, okay, don't talk nonsense, I'll go and get busy first, and I'll talk about it at the special meeting tomorrow."

Xu Dayuan left his phone number and left with his people, Da Zhao blinked and looked at Xiaoqu.

"Are you stupid, let the people in the information department do it, and if you can't do it, you can't leave all the work in our laboratory, right?"

Xiao Quhan smiled and shook his head.

"Actually, it's not too much trouble, but you didn't find the burned phone parts at the scene?"

Da Zhao waved his hand, grabbed a bottle of mineral water, and raised his head to dry.

"What are you looking for, the scene is eager to be sifted through the sieve, we found that these things, either stuck under the floor, or splashed into the corner of the wall, as if a cake box is on the surface, in fact, such a double stubble of eucalyptus is more difficult to get."

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

"It's hard to make a sandwich meal, according to what you said, although the investigation in Jingkou District was done, but the ability was limited, but they also destroyed the scene, adding a lot of trouble to the follow-up investigation, but when you went to the detention center, Dong Chengwen didn't say anything about the cake?"

Zhou Ning shook his head and looked out the window with a sigh.

"I have a feeling that this person surnamed Dong is not telling the truth."

Da Zhao glanced at him, stretched out his fingers, and kept pulling and said:

"It's not my conspiracy theory, his position and identity determine his way of life, there is a certain concealment, he has to pretend to be a good husband and father in front of us, so that you can sympathize with him, try to detect this eucalyptus, and unconsciously want to prove him innocent.

As for his net worth, I can check it on the Internet, people conservatively estimate that millions of dollars are in the account a year, as for the few very famous economic items he handles, the prices are not announced, do you think they lack women?

It's just that they need to create such an identity, in the eyes of customers and peers, a person who takes care of his career and family, which is good for his image. ”
