Wrongful Death Criminal Investigation

Walking out of the inquiry room, it was already 04:30 in the morning.

Zhao Jingwen yawned, her eyes were sore from the long-term intensive concentration, but she didn't delay for a moment, and took the transcript just now to the site of the Serious Crime Brigade on the fourth floor.

In the conference room, Jiang Han from the Forensic Office, Tang Yan from the Trace Inspection Department, and Ming Tang who was on vacation seemed to be waiting for her.

She greeted, "Help me."

Xiao Ding and Lan Ning, who were closest to her, got up immediately, and each of them took the document she was holding and put it on the table.

Zhao Jingwen released her hands and stretched her waist, "Finally I've finished all the questions, but I'm exhausted for my aunt."

Chen Yanjia casually passed a box of milk to Zhao Jingwen, "Miss Ran Ran, drink some milk to replenish her strength."

Zhao Jingwen took it with a smile, "Our Yan Jia still loves others, and whoever marries you is a good fortune."

Chen Yanjia giggled, "That is."

"When everyone is here, let's start the meeting."

In the small meeting room, there is a board that is the same as the multimedia classroom in the school. The difference is that the school is a blackboard, and their meeting room is a white writing board. The two middle ones can be moved. An LCD screen.

On the whiteboard, Mingtang took advantage of Zhao Jingwen and the others to understand the situation, and made a simple summary of the case, and posted the developed photos, the core being Qiu Ziyu.

Mingtang picked up the infrared pen on the table and pressed it, a red dot appeared on the whiteboard, and the red dot landed on Qiu Ziyu's photo, Mingtang cleared his throat and said: "The city attaches great importance to this case and requires us to solve it as soon as possible , so everyone should be prepared to work overtime. Jiang Han, it's up to you to report on the situation."

Jiang Han stood up, walked to the writing board at the front of the conference room, picked up the slender teaching stick placed in the card slot, and knocked heavily on the photo of the deceased, saying: "Because the family of the deceased did not agree to do an autopsy, I also The time of death can only be determined by observing the changes in the body surface of the dead body and measuring the rectal temperature, but this is enough. There are many hand wounds on the body surface of the dead body, and the wounds have life reactions, all of which were caused before death. The degree of cyan fade can be judged to be about three days ago. The scars are mainly concentrated on the waist and abdomen, and all of them have avoided the vital points. In addition, a large number of pinholes were found on the left and right arms of the deceased. It was confirmed by drug testing that the deceased had been injured for two years. There was no drug use."

"It doesn't make sense that there are so many pinholes on the arm without drug use." Xiao Ding questioned.

"That's fine, there can be a lot of pinholes from illness or injection practice or something like that."

Jiang Han continued the topic just now and said, "The deceased had symptoms such as vomiting and diarrhea before death, which was consistent with the characteristics of arsenic poisoning. Therefore, we conducted a poison analysis on the vomit and excrement extracted from the deceased's clothing. The vomit The content of arsenic in the body far exceeds the lethal dose, and it can be confirmed that the cause of death of the deceased was acute arsenic poisoning."

"There were several slight erosions in the mouth of the deceased, and no arsenic residue was detected in the nasal cavity. It is inferred that the poisoning method was oral."

"Acute arsenic poisoning is mainly divided into two types. The deceased belonged to the acute gastrointestinal type. This type of poisoning almost died within a few minutes to several hours after poisoning. Combining the arsenic content in the deceased's body and the time of death, I deduce that the deceased was poisoned. The time is probably between two o'clock in the afternoon and five o'clock in the afternoon. Among the many arsenic compounds, trivalent arsenic and inorganic arsenic are more toxic, and inorganic arsenic is insoluble in water. Trivalent arsenic is the most well-known trivalent arsenic 2 arsenic , commonly known as Shibi cream, is odorless and tasteless, and looks like a white creamy powder, slightly soluble in water, and cannot be found when mixed in meals or drinks."

After a lot of professional analysis and explanations, Jiang Han gave his conclusion: "I think this case is a case of poisoning and murder, but the possibility of accidental ingestion cannot be ruled out."

"Why rule out suicide?"

Jiang Han explained: "Arsenic poisoning is a very painful thing. Not only will there be symptoms such as nausea, vomiting and diarrhea, but also a burning sensation of metallic taste in the mouth, painful spasms and convulsions of the limbs, and respiratory paralysis. Hospital mortality is not 100%."

"A person who really wants to commit suicide is very unlikely to choose this poison. If you don't want to commit suicide, you will suffer if you choose this poison. Arsenic compounds are controlled by the state. If you try your best to get arsenic compounds and don't want to commit suicide, you might as well take two sleeping pills." Come comfortably."

After listening to Jiang Han's analysis, Lan Ning felt more confident, which coincided with his thoughts.

Jiang Han added: "You better hope that Qiu Ziyu didn't eat it by mistake, otherwise the next trend will only be worse."

This kind of case is more difficult to deal with than murder. Compared with serial murder, poisoning is terrible because it can cause mass death. It is far more harmful than serial murder. The victims of serial murder still have a chance to escape. There is no way to avoid it.

After Jiang Han's analysis, the scene fell into a long period of silence. On the one hand, they hoped that Qiu Ziyu had eaten by mistake, and on the other hand, they hoped that they rushed towards Qiu Ziyu, but no matter which direction it was, they couldn't control it.

Tang Yan coughed lightly to break the silence, and said, "I know how the injury on Qiu Ziyu's body was formed. I am a witness."

Everyone looked over in unison.

"The wounds on the waist and abdomen were caused by Qiu Shaoyang."

Lu Changfeng and Mingtang looked at each other, then looked at Tang Yan, "Do you know Qiu Shaoyang very well?"

Tang Yan explained to everyone: "He and I are classmates and roommates in the police academy. We have a very good relationship. After graduation, we entered the city bureau together."

This point was not mentioned in Chen Yanjia's information, so Mingtang didn't know about the relationship between Qiu Shaoyang and Tang Yan.

Lu Changfeng asked, "What happened that night?"

Tang Yan knew that there was no need to hide anything. If he wanted to clear Qiu Shaoyang of his suspicions, it would be of great help to him to explain everything that happened in detail. "Shaoyang came back from abroad. The brothers who have a particularly good relationship made an appointment to meet him at the Style Bar at No. 117 Fenghuang Road. Not only me, but also Huang Wei from the anti-drug detachment next door and Zhao Xingliang from the Provincial Department were present that night. The place was booked by Huang Wei, but we both I didn't expect that Qiu Ziyu was there that night, and I didn't expect that Qiu Ziyu would take the initiative to provoke Shaoyang. At that time, his words were so ugly that I almost made a move, but Shaoyang stopped him. He educated Qiu Ziyu himself. .”

Mingtang frowned, "So what did Qiu Ziyu say at the time? It caused public outrage."

"It probably means that Qiu Shaoyang is the nemesis, the one who can kill the whole family." Tang Yan was still very angry when he said it now, "You should have heard about the fire in the Qiu family eight years ago."

Everyone nodded. This was a big case eight years ago, and it caused a huge commotion in the society.

Qiu Shaoyang’s grandmother, Song Chunlan, was a doctor who went abroad earlier in China. From the 60s to the 90s, she was the best doctor of western medicine in the entire southwest region. She treated as many as [-] patients and made great contributions to the medical construction in the southwest region. It was a great contribution. At that time, many ordinary people spontaneously went to Biluowan to mourn.

"The Qiu family is not as simple as what you see. Although the Tianhao Group headed by Qiu Tianhao and the Qilin Real Estate headed by Qiu Shengqi are cousins, they are not close. They are in business competition and have no contact in private. Qiu Ziyu provoked Shaoyang with the bombing of the Biluowan cruise ship, and the scene at that time was so outraged, Shaoyang couldn't bear it, so he took the initiative to teach Qiu Ziyu a lesson."

After Tang Yan finished speaking, he paused for a while to observe other people's reactions, and then he spoke about his professionalism, "There is no suspicious thing found through the identification of traces on the scene, and it can be confirmed that there is the first death scene. The footprints and Nothing was found on the fingerprints."

Lan Ning continued Tang Yan's words, "The physical evidence has been carefully searched the scene and the private room, and no suspicious physical evidence has been found. The collected evidence is being tested and no problems have been found so far. The detailed inspection report will be released tomorrow morning. available."

"On the contrary, it was found in the surveillance that Qiu Shaoyang had a conflict with the deceased before the death of the deceased. Since there was no surveillance installed in the bathroom, we could not know what happened in the bathroom. From the surveillance screen, we can know that Qiu Shaoyang walked out alone before the death of the deceased. In view of the fact that he had a serious conflict with the deceased before and had a motive for committing the crime, I would like to apply for a search warrant to search Qiu Shaoyang’s residence and summon him to the bureau to cooperate with the investigation.”

"Why did he have the motive for committing the crime?" Tang Yan couldn't help but questioned, "If Qiu Shaoyang wanted to kill Qiu Ziyu, he would never choose the toilet. There are surveillance cameras nearby. With such an obvious flaw, he used to be an excellent criminal investigation policeman. It is impossible not to know that after Qiu Ziyu’s body was discovered, he was the first person suspected by the police! To put it bluntly, he doesn’t need to kill Qiu Ziyu himself, he just needs to hire a professional killer and cause a car accident They are better than this, and he does not lack the money. Taking a step back, if Shaoyang did it himself, he would hardly give us any excuses."

Tang Yan used several impolite words to refute Lan Ning unceremoniously in a row. His tone and attitude were so tough that Lan Ning, who had just arrived, was at a loss for a while.

Tang Yan wanted to continue to speak for Qiu Shaoyang, but was cut off by Ming Tang, "Calm down, no matter how you investigate this case, Qiu Shaoyang cannot be bypassed, even if he is not the murderer, there is still a routine investigation that should be done, just rely on him He is the last person to see the deceased, he should also be investigated, Tang Yan, your qualifications are older than mine, you should know that now is not the time to act on your own will, if you think he is not the murderer, then find the real murderer! Instead of competing here Whoever has the loudest voice has a tougher attitude!"
