Within the Huadu Bureau, Xia Mingxi had already entered all the testimony from the night before.
In the past few days, she stayed up late to investigate cases, her eyes were still dark, and the other people couldn't stop yawning.
Both Liu Mengying and Luo Wei's fingerprints and footprints were registered, and to be on the safe side, the on-duty staff at the Wujian helped to take a blood sample, and now the results have been taken to the library.
Lu Junchi carefully read the relevant information on the Sleeper website provided by Liu Mengying, including the list of recent contacts. He asked several team members to call out the real names of those people according to the list, register them, and contact them again to verify.
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 formulate the statement copy of the joint investigation, and then sent it to the city's police system.
After the post, Xia Mingxi was a little worried: "Team Army, this joint investigation... Will anyone at the sub-bureau respond?"
Qu Ming said: "I think... you should be worried about whether someone will take the blame with an inexplicable case..."
"Across the city, all cases that occurred after June 1, where the murderer is unknown and tried to cover up the truth with accidental death, can initiate a joint investigation to the serious crime team of the Municipal Bureau." Qiao Ze put the email of the joint investigation. The joint adjustment conditions were read again, "I think there are a few detours in the middle of this sentence... Many people in the bureau will be uncertain about the standard."
Lu Junchi was still very calm at this time: "Let's wait and see."
There are so many police officers in Huadu, and there are also Crouching Tigers, Hidden Dragons in the General Bureau, and there are many experienced old police officers. Maybe there will be unexpected gains.
The death case of Liu Mengying's mother was also quickly transferred to the serious crime team.
On the surface, this is a very ordinary accidental death case. The subordinate branch was indeed treated as an accident, and this case even escaped the inspection of the review team.
Liu Mengying's mother is called Zhuang Xueyi. She is the principal violinist of the Hua Ai Orchestra. She has practiced the violin to perfection. People who have heard her performance are full of praise for her. In the symphony music circle, many people like her very much.
Zhuang Xueyi was forty-five years old when he died, and his stature and appearance looked like those of the little girls.
She fell to her death from a stairway in a safe passage after an orchestra performance last year.
If there's one thing about this case that looks different, it's that when it fell, she was holding a large bouquet of white carnations.
At that time, Zhuang Xueyi was wearing her regular clothes, apparently just taking off 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.
When she died, Zhuang Xueyi was wearing a pair of high-heeled shoes. The stairs in the theater were longer than ordinary houses. She rolled down the steps, and the sharp edges hit her forehead and back of her head, killing her on the spot.
The blood that came out stained her clothes and the carnations scattered all over the floor.
The safe passage was not monitored, there were no witnesses, and Zhuang Xueyi had the old problem of low blood sugar. This incident was quickly characterized as an accidental death. It was Liu Mengying who took care of her mother's funeral.
Su Hui stared at the live pictures displayed on the computer, and finally narrowed his eyes, looking at the white carnations under Zhuang Xueyi.
Qiao Ze raised his head and said, "Some people said that Zhuang Xueyi went backstage after the performance. No one has seen her since she changed her clothes."
Lu Junchi judged: "She should have met someone, otherwise there is no way to explain the origin of this bunch of flowers, what about the autopsy results and on-site investigation?"
"The forensic autopsy result said that she died from a fall. In addition, her little finger was stained with some ink marks. It is very likely that she had just signed someone else's name, and there were no footprints and related information left at the scene. Because she had low blood sugar, so At that time, the forensic doctor determined that the blood sugar may be too low, dizziness and fall. Now it seems that there are some doubts. By the way... "
Qiao Ze pulled down the file on the computer again and said, "Liu Mengying was at a friend's house that night, and she has an alibi."
Lu Junchi frowned and said, "It's very likely that this was not an accident, but an intentional murder, but the murderer's method was more clever. He disguised himself as an admirer of Zhuang Xueyi, gave her a large bouquet of flowers, and asked her to sign it, but While there was no one else, Zhuang Xueyi, who was wearing high heels, was pushed down while the two of them went downstairs."
At that time, Zhuang Xueyi was holding a flower in her hand and was caught off guard.
The murderer could lead her to avoid the crowd. It should be someone who was familiar with the backstage, or maybe someone stepped on the spot with him.
The police have also conducted relevant inquiries and investigations before, and they have not found that Zhuang Xueyi has irresolvable conflicts with other people in the troupe.
If it was not an accident, but a murder, what was the purpose of the murder
In this case, Liu Mengying seems to have a vested interest, so does her mother's death have anything to do with her? Who will be the murderer
Lu Junchi stared at the few photos of Zhuang Xueyi's death, and suddenly he saw the bouquet under Zhuang Xueyi's body. It was a bunch of flowers wrapped in pink wrapping paper... You could see some dyes on the wrapping paper. Blood patterns and numbers, that could be the phone number of a flower shop…
"Joze, try and see if you can extract the information on the bouquet wrapping paper, see which flower shop sold these flowers, and ask the flower shop along the way to see if you can find someone who bought the flowers..." He looked at it again and said, "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 fingerprints of the deceased, 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 too common, and it may be wrong to take it. And the two fingerprints are incomplete, but it can be judged that they do not match the fingerprints of the deceased, and they cannot even be compared to the murderer." Qiao Ze said, "Maybe At that time, the police in those precincts thought it was an accident..."
Lu Junchi looked at it again and said, "Anyway, this case is still suspicious. Let's investigate it first."
At this moment, someone knocked on the glass door of the serious crime team.
Lu Junchi looked up and saw Xing Yunhai, the captain of the fifth criminal investigation team, standing outside.
Seeing this, Lu Jun got up and greeted him. He patted Su Hui when he passed by, and then made a gesture to Qiao Ze to show them together.
An hour ago, the team members were still worried that no one would respond to the joint investigation, but they did not expect that someone would come to the door so quickly.
Xing Yunhai greeted several people.
Qiao Ze obediently and consciously took the record book and prepared to record the meeting.
Lu Junchi asked: "Xing team, do you have any clues?"
Xing Yunhai raised the file in his hand and said: "I saw the joint investigation statement issued by the serious crime team, and immediately thought of this 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 that, Xing Yunhai had always felt that the carbon killing case was indescribably weird. Today, when he saw the email, he felt that it might be related, so he killed it himself.
Lu Junchi took Xing Yunhai to a small conference room aside.
Xing Yunhai spread out the file: "A few days ago, a woman came back from a business trip and found that her husband burned charcoal and died 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 more clues in Zhuang Xueyi's case before, but the case in front of him has obvious loopholes.
Xing Yunhai didn't expect Su Hui to make a decision so quickly. He also vaguely felt that there was a problem after on-site investigation and inquiries. He couldn't help but ask, "Where did you find it?"
Su Hui lowered his head and said calmly, "First of all, the site is too clean. It's actually not that easy to burn a charcoal pot, igniting wax and charcoal packaging, which I haven't seen on the site. Maybe, the carbon was 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 devices, which was indeed unreasonable.
Su Hui used his slender fingers to pull out several other photos of the deceased: "The second is the flies, such a small charcoal basin, placed in the bedroom, the room must be completely airtight to be able to kill. So many flies, indicating that there are The personnel later went to the scene and confirmed that the deceased was dead. Because he was afraid that the carbon monoxide inside would cause poisoning, he opened the door and forgot to close it. The murderer was very nervous and should not be a veteran. "
Xing Yunhai nodded: "Mr. Su's analysis is very reasonable. I also confirmed from the appearance of 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 was detected in the blood of the corpse. It is likely that the victim was asleep after taking the sleeping pill, 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... It's an acquaintance, or he came to step on it."
Xing Yunhai said: "In addition, I also found that the deceased had neurasthenia, but his wife kept a bag of tea leaves and some coffee in the kitchen. I suspected that she had put something that affects sleep in some food. It is to aggravate his husband's insomnia, and then ask him to go to the doctor to prescribe sleeping pills, causing sleeping pills dependence, the purpose is to not be disturbed when the charcoal basin is placed."
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: "No fingerprints or footprints were 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, and the husband has Affair, always disagreeing with divorce, all of which may lead to murder. However, during this period, my wife had sufficient alibi. Although there were some loopholes in her confession, there was no obvious evidence. I tried to find out from her daily contacts. There are traces of buying fierce, but no breakthrough has been found..."
Lu Junchi looked down at his wife's name and crossed his finger on 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..."
The case was found here, and they found some more direct connections between the Sleeper Forum and the death case...
Xing Yunhai asked, "Is this woman the person involved in your related case?"
Lu Junchi replied conservatively: "It's not completely determined yet, but I think this connection should not be accidental."
Someone was talking next to him, Su Hui was a little distracted, and he listened vaguely, as if Lu Junchi was introducing Xing Yunhai about the progress of the case on the serious crime team.
In this case, Gu Ruoruo undoubtedly had a motive for killing her husband.
The perpetrator may have been subtly hidden. Xing Yunhai's investigation of this case has been limited to normal contacts and social relations.
But just imagine, if a stranger who seems to have nothing to do with her on the surface kills her husband, then such a murder method will undoubtedly bring huge difficulties to the police's detection work.
Su Hui sat aside and looked at the form and the file in front of him. Those documents were blurred in his eyes, but all the details suddenly came to his mind.
Now, they have just found the direction of the cases, which are like a straight line, extending towards both ends.
Is Zhuang Xueyi's death the first case they are 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 encounter.
Lu Junchi and Qiao Ze began to discuss the commonalities between the cases and whether there was the same murderer. However, there are many differences in the details of the case.
Qiao Ze walked to the whiteboard and sorted out the known relationships of the characters in the case. The clues were intricately drawn.
Su Hui could only see a bunch of tangled threads from a distance.
He suddenly remembered what Liu Mengying had said to him before...
She repeatedly emphasized the word "help".
She wants to offer him "help".
As a real depressed patient, what kind of help does he need
Su Hui coughed a few times. He thought that at some point in the past, it was very likely that Liu Mengying had seen this Gu Ruoruo, and she might have said the same thing to her...
A burst of tinnitus suddenly came from the deaf left ear, which caught him off guard. Su Hui couldn't help but put his hand beside his ear and endured the discomfort. More evidence will be needed to confirm.”
