Criminal Investigation Notes

In the Huadu City Bureau, Xia Mingxi had already entered the statement from the night before yesterday.

She stayed up all night investigating the case these days, her eye circles were still dark, and the others couldn't help yawning.

The fingerprints and footprints of Liu Mengying and Luo Wei have been registered, and just to be on the safe side, the on-duty staff at the Biology Academy took a blood sample, and now the results have been taken to the warehouse.

Lu Junchi carefully read the relevant information on the Sleeper website provided by Liu Mengying, including the list of people he had contacted recently.He asked several team members to call up the real names of those people according to the list, register them, and then contact them for verification.

Lu Junchi went to talk to Bureau Tan yesterday afternoon, and got the official approval for the joint investigation before noon today.

Xia Mingxi helped draw up the statement of the joint investigation, and then sent it to the city's police system.

After sending it out, Xia Mingxi was a little worried: "Team Lu, this joint investigation... Will anyone from the sub-bureau respond?"

Qu Mingdao: "I think...you should be worried that someone will take the blame with some inexplicable case..."

"In the whole city, all cases that occurred after June [-], where the murderer is unknown, and where accidental death is used to cover up the truth, can initiate a joint investigation with the serious crime team of the Municipal Bureau." Qiao Ze shared the joint investigation email After reading the joint commissioning conditions, "I think there are a few twists and turns in this sentence... Many people in the sub-bureau will be uncertain about the standard."

Lu Junchi was still very calm at this moment: "Let's wait and see."

There are so many police officers in Huadu, and there are also crouching tigers, hidden dragons in the branches of the headquarters. There are many experienced old policemen, and there may be unexpected gains.

The case of Liu Mengying's mother's death was quickly transferred to the serious crime team.

On the surface, this is a very common case of accidental death.The subordinate branch really handled it as an accident, and this case even escaped the inspection of the review team.

Liu Mengying's mother is Zhuang Xueyi, who is the chief violinist of the Hua Ai Orchestra. She has practiced the violin to perfection, and everyone who has heard her performance is full of praise for her.In the symphony music circle, many people like her very much.

Zhuang Xueyi was 45 years old when she died, and her figure and appearance didn't look like those little girls at all.

She fell to her death after accidentally falling down the stairs in the safety passage after a band performance last year.

If there was one thing about the case that looked unusual, it was that when it fell, she was holding a large bouquet of white carnations in her hand.

At that time, Zhuang Xueyi was wearing her regular clothes, obviously she had just removed her makeup backstage.

According to the testimony of her colleagues, Zhuang Xueyi's makeup that day was very complicated and troublesome, and it took a lot of time to remove it, so she came out much later than other actors.

At the time of her death, Zhuang Xueyi was wearing a pair of high heels, and the stairs in the theater were longer than ordinary houses. She rolled down the steps, and the sharp edges hit her forehead and the back of her head, killing her on the spot.

The blood that flowed out stained her clothes and the carnations scattered on the ground.

The safe passage was not monitored, there were no witnesses, and Zhuang Xueyi suffered from hypoglycemia. This incident was quickly classified as an accidental death, and it was Liu Mengying who took care of her mother's funeral.

Su Hui stared at the scene picture displayed on the computer, and finally squinted his eyes, looking at the white carnations under Zhuang Xueyi's body.

Qiao Ze raised his head and said, "Someone said that Zhuang Xueyi went backstage after the performance, and no one saw her after she changed her clothes."

Lu Junchi judged: "She must have met someone, otherwise there is no way to explain the origin of this bouquet, what about the autopsy results and on-site investigation?"

"The autopsy result of the forensic doctor said that the death was caused by a fall. In addition, there were some ink marks on her little finger. It is very likely that she had just signed someone else's name. No footprints or related information were left at the scene. Because she had hypoglycemia, so At that time, the forensic doctor judged that the hypoglycemia may have caused dizziness and fell. Now it seems a little suspicious. By the way..."

Qiao Ze scrolled down the file on the computer again and said, "Liu Mengying was at a friend's house that night, and there is an alibi."

Lu Junchi frowned and said, "It's very possible that this wasn't an accident, but an intentional murder. It's just that the murderer's method was more ingenious. He pretended to be Zhuang Xueyi's admirer, gave her a large bouquet of flowers, and asked her to sign it. Taking advantage of the fact that there was no one else, while the two of them were going downstairs, they pushed Zhuang Xueyi who was wearing high heels."

At that time, Zhuang Xueyi was holding flowers in her hands and was caught off guard.

The murderer was able to lead her to avoid the crowd. He should be someone familiar with the backstage, or in other words, someone might have stepped on him with him.

The police had also conducted related inquiries and inquiries before, and they did not find that Zhuang Xueyi had unresolvable conflicts with other people in the troupe.

If this was not an accident, but a murder, what was the purpose of the killing?

In this case, Liu Mengying seems to have a vested interest, so is her mother's death related to her?Who will be the murderer?

Lu Junchi stared at the photos of Zhuang Xueyi's death, and suddenly he saw the bouquet of flowers under Zhuang Xueyi's body. It was a bunch of flowers wrapped in pink wrapping paper... Some dyed flowers could be vaguely seen on the wrapping paper. There are blood patterns and numbers, it may be the phone number of the flower shop...

"Joze, try to see if you can extract the information on the bouquet wrapping paper to see which florist sold the flowers, and then ask the florist to see if you can find the person who bought the flowers... He looked at it and said again, "What is this?"

There is a small thing on the ground.

Qiao Ze checked the information and said, "A pen is suspected to belong to the deceased, but in the later tests, in addition to the deceased's fingerprints, two incomplete fingerprints were found on it."

Lu Junchi frowned and said, "Why didn't you pay attention to such an important evidence?"

"A pen is so common, you might get it wrong. And the two fingerprints are incomplete, but it can only be judged that it doesn't match the fingerprint of the deceased, and it can't even be compared with the murderer." Qiao Ze said condescendingly, "Maybe At that time, the policemen in those sub-bureaus thought it was an accident..."

Lu Junchi looked at it again and said, "Anyway, there are still doubts about this case, let's investigate further."

At this moment, someone knocked on the glass door of the serious crime unit.

Lu Junchi raised his head and saw Xing Yunhai, the captain of the fifth criminal investigation team, standing outside.

Seeing this, Lu Junchi stood up to meet him, patted Su Hui as he passed by, and then gestured to Qiao Ze to signal them to come together.

An hour ago, the team members were worried that no one would respond to the joint investigation, but they did not expect that someone would come to the door so soon.

Xing Yunhai greeted several people.

Qiao Ze took the notebook obediently and consciously, preparing to take minutes of the meeting.

Lu Junchi asked: "Captain Xing, do you have any clues?"

Xing Yunhai held up the file in his hand and said: "I saw the joint investigation statement issued by the serious crime team, and immediately thought of the case at hand. This case is a homicide case that has been disguised, but the murderer has not yet been found." , so I procrastinated for a while and never closed the case."

Before this, Xing Yunhai always felt that the carbon killing case was indescribably weird. When he saw the email today, he felt that it might be related, so he directly killed it himself.

Lu Junchi brought Xing Yunhai to a small meeting room beside him.

Xing Yunhai spread out the files: "A few days before the incident, a woman came back from a business trip and found her husband burned to death on the bed in the bedroom."

Su Hui also looked down at the picture of the crime scene on the table. He looked at it for a few seconds and said in a low voice, "It was murder."

He didn't find any more clues about Zhuang Xueyi's case before, but this case in front of him obviously has a bigger loophole.

Xing Yunhai didn't expect Su Hui to make a decision so quickly. He also vaguely felt that there was something wrong after the on-site investigation and inquiries, so he couldn't help but ask, "Where did you see it?"

Su Hui lowered his head, and said calmly: "First of all, the scene is too clean. Burning a charcoal basin is actually not an easy task. I didn't see the wax and carbon packaging bags at the scene. Very Possibly, the carbon was already burned downstairs or somewhere and brought to the scene."

Xing Yunhai couldn't help nodding, the scene was too clean, and they didn't find any other ignition device, which is really unreasonable.

Su Hui used his slender fingers to dig out several other photos of the deceased: "Secondly, there are flies. Such a small charcoal basin is placed in the bedroom. The room must be completely sealed to be fatal. There are so many flies, it means that there are The personnel later went to the scene and confirmed the death of the deceased. Because he was afraid of the carbon monoxide inside causing poisoning, he opened the door and forgot to close it. The murderer was very nervous, so he should not be a veteran."

Xing Yunhai nodded: "Mr. Su's analysis is very reasonable. I also confirmed from the appearance of the flies that the house was entered later."

Lu Junchi pointed to the autopsy report on the file and added: "A small amount of sleeping pills were found in the blood of the corpse. It is likely that the victim was asleep after taking sleeping pills, and the room was invaded and a charcoal basin was placed..."

He looked at the photo again and said, "That charcoal basin is easy to make noise. The murderer needs to be familiar with the environment and know the direction of the bedroom...he is an acquaintance, or he has stepped on it."

Xing Yunhai said: "In addition, I also found that the deceased had neurasthenia, but his wife put a bag of tea leaves and some coffee in the kitchen. I suspect that she put something that would affect sleep in some food for the purpose It is to aggravate his husband's insomnia, and then let him go to the doctor to prescribe sleeping pills, causing him to become dependent on sleeping pills, and the purpose is to not be alarmed when placing the charcoal basin."

Lu Junchi frowned: "So, this murder may have been planned for a long time? It sounds like my wife is very suspicious."

Xing Yunhai nodded in agreement: "There were no fingerprints or footprints left at the scene. The murderer sneaked in in the dark. I also visited the object of my husband's affair and ruled out the suspicion. At present, the wife is the most suspected. The husband has Having an affair and not agreeing to a divorce all the time, all of these may form a murderous intent. However, during this period, my wife had a sufficient alibi. Although there were some loopholes in the confession, there was no obvious evidence. I tried to find out from her daily contacts. There are traces of buying murder, but no breakthrough has been found..."

Lu Junchi looked down at his wife's name, and ran his finger over it: "Gu Ruoruo, this name looks familiar."

He got up and went to get the summary sheet he was looking at just now, and sure enough, he found the same name on it.

"According to Liu Mengying's confession last night, the sleeper contacted her..."

After the case was found here, they found some more direct connections between the Sleeper Forum and the death case...

Xing Yunhai asked: "Is this woman related to your case?"

Lu Junchi replied very conservatively: "It is not completely confirmed yet, but I think this connection should not be accidental."

Someone was talking next to him, Su Hui was a little distracted, listening vaguely, it seemed that Lu Junchi was introducing the progress of the serious crime team to Xing Yunhai.

In this case, Gu Ruoruo undoubtedly had a motive to kill her husband.

The perpetrator might have been subtly hidden. Previously, Xing Yunhai's investigation of this case had been limited to normal contact and social relations.

But just imagine, if a stranger who seemed to have nothing to do with her on the surface killed her husband, then such a murder method would undoubtedly bring great difficulty to the police's detection work.

Su Hui sat aside, looking at the form and the file in front of him. Those documents were blurred in his eyes, but all the details were suddenly remembered in his mind.

Now, they have just found the direction of the case. These cases are like a straight line extending towards both ends.

Was Zhuang Xueyi's death the first case they were looking for, and Pang Qinghua's death the last case closest to them?

There is no doubt that the two cases have something in common, but they are somewhat different from the general cases they encountered.

Lu Junchi and Qiao Ze began to discuss the commonality between the cases, whether there is the same murderer.But from the details of the case, I feel that there are many differences.

Qiao Ze walked to the whiteboard and sorted out the known relationship between the characters in the case, drawing intricate clues.

From a distance, Su Hui could only see a bunch of tangled threads.

But he suddenly remembered what Liu Mengying had said to him before...

She repeatedly emphasized the word "help".

She was going to offer him "help."

As a real depressed patient, what kind of help does he need?

Su Hui coughed a few times, and he thought that at some point in the past, Liu Mengying might have met this Gu Ruoruo, and she might have said the same thing to her...

There was a sudden tinnitus in his deaf left ear, which caught him off guard. Su Hui couldn't help but put his hand next to his ear. After enduring the discomfort, he said, "I seem to understand a little bit, but I still need to More evidence will prove it."
