Inside the evidence bag was a delicate thermos cup. The ivory cup is painted with blue and white flowers.

"Poisoned?"

Sun Meng's always calm face couldn't help but show a little surprise at this time. Of course, this slight change was fleeting in his face.

"A preliminary inquest at the scene of the body was superficially intact and there were no obvious external damage. At the same time, judging from the location of the corpse spot, the blood of the corpse should be dark red and fluid. Epiglotto, larynx, glottis with hyperemia and edema. Zhang Zhichao held a few fixed photos of the scene in his hand and continued to introduce.

"Although further autopsy is needed to determine whether there is intermyocardial edema, myocardial rupture and other signs of death in the body, it is undoubtedly toxic shock based on the fact that the deceased at the scene had suffered from incontinence before death."

"What kind of poisoning did you just say?" Sun Meng stared at the corpse, his right hand gently twisting his chin.

"Acetylsalicylic acid."

"Huh?" Sun Meng suddenly frowned, hooked his right index finger and scraped his nose.

A doctor with such a rich medical background was actually poisoned by aspirin, or rather, who could poison a doctor with aspirin.

"It's really hard to deal with..."Sun Meng pursed his lips, and his right index finger and middle finger gently circled around his chin, which was his habitual action to restore the case.

At this moment, several police officers from the forensic department were busy at the scene. They also came over from time to time to whisper a few words to Zhang Zhichao. Sun Meng walked out of room 1302 where the body was found, opened the pipe well in the corridor and carefully examined it with an exploration lamp.

"Da Chao!" Sun Meng, who walked back to the south bedroom to check the body carefully, suddenly greeted Zhang Zhichao, who had just walked out of the bedroom, and turned around.

"Tell me about any other clues, shall we?" After determining the cause of death and the approximate time of death of the deceased, Sun Meng got up and looked around the house. Zhang Zhichao's report made it easy for him to further collect clues and sort out his ideas.

Zhang Zhichao's face was flushed, and he scratched his head through the disposable sterile cap, and stopped talking.

"You?" Sun Meng was a little confused by his series of actions.

"Oops! Moe Team! After all, Zhang Zhichao is just a forensic rookie, and the fact that he has the city government in his mind is not what he is good at. He took a step in front of Sun Meng, and said with a tangled face: "Team Meng, you also know that our forensic doctor can restore the case according to the clues known at the scene, and even let the corpse 'speak' by itself through an autopsy." But we are not gods, although I have also struggled with the cause of death of the dead, but..."

Zhang Zhichao gritted his teeth: "After Gu Xiang and I checked the monitoring of the community and the unit, we did not extract any other valuable clues at the comprehensive scene except for the deceased and the cause of death. In other words, the site is so clean! Clean enough to be suicidal. ”

"Suicide?" Sun Meng didn't let out a mouthful of old blood. Although there was still a corpse lying here, Zhang Zhichao's wide-eyed and serious face still made Sun Meng almost smile unkindly. Of course, the basic moral cultivation of the policeman "saved" him at a critical moment.

"Look, Team Moe." Zhang Zhichao continued: "When we arrived at the scene, we found that the door of the deceased was locked from the house. At the same time, after our on-site investigation, the bay windows in the north and south bedrooms of the house, the square windows facing southeast in the kitchen, the skylight in the attic and even the ventilation windows in the bathroom are all closed and intact. In addition to the deceased's hair, fingerprints, and traces of life, there were no traces of the existence of the second person in the room. Besides, this is the thirteenth floor! The murderer doesn't appear out of thin air, does he? ”

Sun Meng nodded, and the index and middle fingers of his right hand were still gently circling around his chin.

"So you think that since there is no trace of the suspected murderer at the scene of the crime, and at the same time, the financial murder is ruled out according to the deceased's property, and the good reputation of the neighbors excludes vendettas, and the deceased is left with only one possibility, which is suicide, right?"

"Otherwise, what about the cute team? The deceased was a university professor with a medical background! It shouldn't be difficult to get an aspirin, right? Zhang Zhichao is obviously confident. After all, as a forensic doctor, everything on the scene seemed more inclined to the verdict he gave.

"Then why haven't you decided the case yet?" Sun Meng's tone was still unhurried.

"This..."Zhang Zhichao grinned: "You're not joking with me, cute team!" In our Tanigawa City, only Master and Brother Kai have the qualifications to be the chief examiner! Although I am also a forensic doctor, we are not qualified to conclude the case without passing the test. ”

"I'm special!" Sun Meng raised his slap, which frightened Zhang Zhichao subconsciously covered his face. "I really want to smoke you! You can also call a forensic doctor! At your level?! I should have asked Lao Zhang to remove you! No wonder the provincial department still wants Lao Li to do it himself! ”

"Come," Sun Meng motioned to a trainee forensic doctor in the forensic medicine department to pull the body back to the forensic identification center for further autopsy. Then he pulled Zhang Zhichao to the living room, crossed his fingers and asked, "How many motives are there for the killing, let me ask you?" You deserve to be the chief forensic physician and can't get down! What about love killing? Have you ruled out the motive for me to kill? ”

"I..."

"Ah, just based on the divorce from the informant's mouth for ten years, no one has been in and out of the deceased's house a few days before the incident? I ask you, can this be used as evidence, brother? ”

"It's not the Meng team, I..." Zhang Zhichao looked a little distracted under Sun Meng's repeated questions, and his face was also "Teng" to the base of his neck. "Why are you sure that the deceased did not commit suicide?"

"The more real things we see with our eyes, the more they turn out to be not what we think they are. Until your forensic autopsy report is stamped, I'm not sure that the deceased must have committed suicide. But I don't think he can be ruled out. Sun Meng picked up a few evidence numbers and looked at them carefully.

"First, as a forensic doctor, you directly ignored a very important detail on the scene. It has been almost 24 hours since the death of the deceased, and our city of Tanigawa has a typical subtropical monsoon climate, which is 'rain and heat at the same time'. In such a closed environment, why didn't the corpse accelerate the decay and produce the giant view? ”

"Moe team, it will take about 48 hours for the corpse in summer to produce a giant view, right?"

"You came to the team at about the same time as Zhou Kai, why are you now the chief forensic physician, haven't you thought about it? The book tells you 48 hours, does it tell you that the generation of the giant view is also affected by the environment, temperature, cause of death, and personal physique? Conduct a site survey, don't just be confined to what you think you are. ”

Sun Meng took Zhang Zhichao to the room again, and several policemen nodded to him.

"Kala!" Sun Meng stretched out his hand to pull open the power box under the dining table in the living room, and several downward switches appeared in front of them.

"Do you see?" Sun Meng pointed to the switch in front of him and said, "This is the main switch in the house, I just went to the corridor to check the pipe well and checked the meter by the way." The reason why the deceased's doors and windows were closed was because the air conditioning was turned on in the house at that time. The deceased is supposed to have been in shock and died shortly after the air conditioner was turned on, because the air conditioner was working all the time, so the temperature in the house could be kept relatively low even when it was closed. And this temperature just doesn't allow the decay of the corpse to happen so quickly. Later, when the electricity bill ran out, the main switch tripped, and the air conditioner stopped working, and the open fan blades were automatically closed. So let me ask you, a person who is about to choose suicide still cares about whether the temperature in the house is suitable before he dies? ”

Zhang Zhichao nodded, silently thinking about Sun Meng's words in his heart.

"I often warn the people in our team not to be 'preconceived' as a criminal investigator. It's true that you haven't turned on the lights to avoid the interference of the lights on the scene, but you can't help but observe the condition of the circuits in the house. There was no electricity in this house from the beginning, and you haven't even noticed such a detail until now. ”

Zhang Zhichao lowered his head embarrassedly: "Meng team, you continue." ”

Second, the informant Guo Song said that it was because he asked about the pungent smell and did not see the deceased He Shipeng for many days and felt that something was wrong. The corpse did not decompose, and the time of death was about 24 hours, so there was no corpse odor in this house. Even if the deceased had incontinence before his death, this was not enough to support the report's description of 'a pungent smell coming from the house'. When I came up, I smelled the hallway. After checking the pipe well, there was no backwater, everything was normal. So I couldn't figure out how the 'smell' in Guo Song's mouth came from. Therefore, I suggest that this Guo Song be investigated first, and then all of He Shipeng's social connections should be investigated. ”

"Okay, I'll do it right away!" Gu Xiang, who had been silent next to Sun Meng, nodded at this time.

"The most important third," Sun Meng stretched out three fingers, "from the analysis of the psychological motivation of the suicidal, the appeal of the person who has made up his mind to commit suicide is 'death'." Based on the success rate of achieving 'death' and the consideration of reducing the original demands of the suicidal person due to the unnecessary suffering in the process of avoiding, 'quick death' is the only goal. So I ask you, under what circumstances does aspirin cause death? ”

"Drink." Zhang Zhichao blurted out.

"It's good that acetylsalicylic acid will stop the deoxygenation of acetaldehyde. So I ask you, how to control the dosage and time? As a famous doctor in Tanigawa City with a rich medical background, how much misunderstanding did he have about himself to choose such a long and not necessarily high-powered way when preparing to commit suicide? In addition, as you said, did your forensic doctor extract the key evidence of this case, 'wine', at the scene? ”

"Team Meng, I'm convinced..."Zhang Zhichao arched his hand with a big grin, but his eyes were still full of doubts: "But Team Meng, the scene is completely a secret room, how did the murderer come in and poison him, and how did he retreat without leaving a trace?" ”
