Yu Baofu continued: "I chatted with that Wang Honggui in the afternoon, and he always emphasized that he was to blame for this incident, and it was he who did not turn off the power switch of the wheelchair, which caused his wife to have an accident after accidentally touching the control lever. ”

"I don't think it was an accident. Durin said suddenly.

"What is Lao Du's opinion?" asked Li Xian.

"First of all, let's ask Dr. Zhuang to tell us about the deceased's blood test. Dühring pointed to the Zhuangpo stone.

Zhuang Poshi immediately stood up, "Hello everyone, the first time we meet, I will introduce myself first......

"Needless to say, we all know you, Dr. Zhuang, we usually pay attention to Dr. Du, and we have watched you and his event. ”

"Oh, that's what makes you laugh. Zhuang Poshi was a little embarrassed, he was a failure in that competition, he had been immersed in the confusion of the collapse of his position, and he hadn't thought much about the question of victory or defeat...... Fortunately, he fired his assistant.

However, it was not because Zhuang Poshi was ruthless and unrighteous, nor did he feel that he couldn't get by with the assistant, but simply because he couldn't afford to hire it, he donated half of his salary as a visiting professor and worked for Du Lin for free, and his income plummeted, and he really couldn't afford the assistant's salary.

"Let's start with the patient's ...... I'm sorry for always saying' The patient said that he was used to it, the blood toxicology report of the deceased came out, according to the residual concentration of trazodone in the blood, she took at least three times the normal dose that day, which is very abnormal, because according to the medicinal properties of trazodone, take it according to the instructions, basically there will be no drowsiness side effects, but the instructions are the minimum dosage, the general doctor will not give the patient medicine according to the instructions, if you take the medicine according to the doctor's recommended dosage, there may be certain side effects, but if you take it according to three times the dosage, 100% drowsiness, Symptoms such as fatigue. ”

"I saw on their bedside, on the small note in the medicine box, the record of this morning's medication was a normal dose. Durin said meaningfully.

"What do you mean...... This is not an accident, at least Deng Ting's fall is suspicious?" asked Li Xian.

"If there are no suspicions, I'm sure you don't need to have any case analysis meetings, right?" said Durin.

"Of course, we're not idle. Li Xian flipped through a folder," We also did some background checks, at first we wondered if this was a case of murder and insurance fraud, but neither of them found a large amount of personal accident insurance in their names, so we changed the angle to see if the two people have any large amount of property in common, although the two live in affordable housing, the income is also very average, Deng Ting does not even have a job, but we found a point, Deng Ting's hometown is about to face demolition, Deng Ting's grandfather left an old house in the family to Deng Ting before his death, the head of this house has now changed its name to Deng Ting, and the demolition compensation of this house is quite considerable, enough to more than 4 million。 ”

"That's enough to make people feel killed. Durin nodded.

"There is a motive, but, we have no evidence now, judging from the time and the testimony of eyewitnesses at the scene, Wang Honggui did not have the time to commit the crime, and there is no trace of anyone else entering the house where the crime occurred, the incident occurred on the weekend, his family's part-time worker did not come to work, and the cost of hiring a murderer is too high, it is unlikely. Li Xian said.

"It's not that there is no time to commit the crime," Du Lin took out a small notebook, "In the afternoon, Peake and I went to the community where the crime occurred, Wang Honggui was about the same size as me, so the two of us should be very similar in length, that is, the speed of walking, I followed the route he said." Is there a floor plan for the neighborhood?"

Qu Mingming said busily: "Yes." After speaking, he typed out the floor plan of the community on the projector.

Durin said, pointing to the picture,

"Just now Jie Shu said that he returned to the community after buying things is 9:15, the neighbor called the police at 9:29, a total of 14 minutes have passed in the middle, from Deng Ting landed to be found by other neighbors, and then it takes time for the neighbor to call the police, we count him three minutes, Wang Honggui walked from the gate of the community to the place where he met his neighbors, I measured, it took six minutes, the two also chatted a few words, I counted it for one minute, fourteen minutes minus three minutes, then six minutes, one minute less, there are four minutes left, his house is on the seventeenth floor, the elevator goes up to the seventeenth floor and then comes down to the place where he meets his neighbors, four minutes is obviously not enough。 ”

"That's right, that's why we said he didn't have time to commit the crime?" said Li Xianyi.

"What if he doesn't need to go upstairs?" said Durin.

"Don't go upstairs?" Li Xian was stunned, "How can you not go upstairs? Although that wheelchair is electric, it is not remote-controlled?"

"I'm just putting forward an idea, a possibility, and how to realize it needs to be investigated by your police. Durin also spread his hands.

"Then you don't mean you didn't say it. ”

"I don't say, how can you think of investigating, how can you kill people without being at the scene?"

Li Xian thought about it, and it really was. If Du Lin did not raise the possibility of being able to control the wheelchair downstairs, they might have really ruled out Wang Honggui's suspicion, which would be tantamount to ignoring an important direction in handling the case.

"Then let's do it, Baofu, you can contact that Wang Honggui again to see if he will show any horses' feet, and the others will find a way to see how they can control the wheelchair downstairs. That's all for today, let's disperse. ”

Everyone got up and went home, and Zhuang Poshi whispered to Du Lin, "Is this the end of it?"

"Ah, what else do you want to do?" asked Dulin rhetorically.

"Don't I have to watch all kinds of analysis, all kinds of reasoning, peeling back the cocoon, looking for clues little by little or something?"

"You've watched too many TV series. Durin closed his notebook and got up and left.

The next morning, Du Lin and Li Xian came to the scene of the crime again, that is, the place where Deng Ting fell from the building, this is a grass in front of the building, of course, the body has already been sent away, and the shed covering the body has also been demolished, but the blood stains on the grass are still there.

Du Lin looked around, the greening of the community is very good, in addition to the grassland, there are also a lot of fruit trees planted around, there are several dense fruit trees within a few meters around the place where Deng Ting landed, just enclosing the landing site in the middle, so that the landing site forms a relatively closed environment, that is to say, what to do here, it is not visible from the road in front of the building.
