"I'm done!" Bai Mo stopped his pencil. He looked at Chen Xiaoxiao and Fu Xingliang and found that they were looking at each other stupidly.
Bai Mo stretched out his hand and waved it at the intersection of their eyes, and then the two of them came back to their senses.
The next second, the two stood up at the same time and rushed out of the security room like crazy.
Bai Mo was completely immersed in painting just now and didn't hear the conversation between the two at all. He saw that the two must have made a major discovery and immediately followed them.
Back downstairs in Building 5, Chen Xiaoxiao said to Xing Liang: "You hold the door and don't let anyone in or out for the time being."
After the explanation, Chen Xiaoxiao ran into the building. Bai Mo did not follow him. He stayed to ask Fu Xingliang about their findings.
"Do you suspect that the murderer is still in the building?" Bai Mo said in surprise.
Although Bai Mo didn't have much experience in handling cases, he could tell that the murderer must have run away. After killing two people and still staying here, wasn't he looking for death?
"Surveillance will not lie!" Fu Xingliang explained, "The murderer may have hid in the building after the murder, and waited until dawn to blend in with the owners at work and leave the unit building. In that case, it must be covered up tightly. It will arouse others' suspicion, and we can find the murderer just by comparing the people who left the unit building after the crime."
"Of course, there is another situation." Fu Xingliang took a deep breath, "that is, the murderer is the owner of the building!"
Bai Mo shook his head. The murderer was so well prepared, how could he not think of a way out?
Although Bai Mo disagreed with Fu Xingliang's inference, he did not continue to argue. After all, the murderer did not leave the building under surveillance.
Fu Xingliang glanced at Bai Mo's backpack, "Didn't you just finish the painting? Can you let me see your portrait?"
Although Fu Xingliang is just a small-time police officer, his ideal is to become a criminal police officer. Unfortunately, the criminal police team rarely recruits people, and the occasional recruitment is basically predetermined.
For example, the Bai Mo in front of him, Fu Xingliang's experience, he could tell that Bai Mo didn't have much experience in handling cases, and he could also tell that Bai Mo was a portrait artist of the criminal police team.
With a little bit of comparison mentality, Fu Xingliang wanted to know what kind of portrait Bai Mo could draw.
Bai Mo took the portrait out of his backpack and handed it to Fu Xingliang.
When he first saw the portrait, Fu Xingliang had an idea of what it was. Then when he thought about the murderer's tightly covered face, he calmed down and observed it himself.
This painting only has the outline of a face, no mouth, a very clear nose, not too tall, but rather wide. There are a pair of eyes, but no pupils or eyebrows.
"Can you determine his nose?" Fu Xingliang was a little shocked. He felt that if Bai Mo couldn't determine the murderer's nose, he would definitely not draw such a detailed picture.
"Sure!" Bai Mo's tone was full of confidence, "When I get back to the police station, I will try to draw his eyes and mouth based on the proportions of common faces. I just don't know how many combinations there will be."
"Suck-" Fu Xingliang suddenly had a new understanding of criminal police. If he didn't have this skill, he would be embarrassed to be a criminal police officer!
A few minutes later, a head popped out of the window of the stairwell on the second floor. Lu Wan looked at the window, and then appeared on the first floor with Chen Xiaoxiao and a forensic doctor.
Lu Wan went directly to the grass outside the building opposite the window, knelt down and took a closer look, then stood up and waved to the forensic doctor who was following.
Bai Mo and Fu Xingliang walked over. Chen Xiaoxiao was asking Lu Wan for advice, "Lieutenant Lu, there was no trace of rope friction on the window. Why do you think the murderer climbed out from the second floor window?"
"The time is wrong." Lu Wan looked up at the window on the second floor. "The murderer entered the stairwell at 12:45 and arrived at the 25th floor at 1:05. It took a full 20 minutes. From the underground It only takes 10 minutes to walk from the parking lot to the 25th floor. The murderer would walk very fast to avoid being discovered, so it must be less than 10 minutes.
So what was he doing in the remaining 10 minutes? It should be preparing an escape route from the second floor window! He can use smooth cloth to make a loop of rope, get down from here and cut the rope, and the rope can be easily pulled away. The lawn here has been trampled down, that's what it should be. "
Lu Wan pursed her lips and shook her head, sighing: "This murderer is so professional. Now I kind of suspect that he hired a murderer to kill someone."
······
After a morning of investigation, the criminal police team returned to the Public Security Bureau office. Qin Youwei's autopsy has been completed, and the first case discussion meeting has begun.
"Why do you come here every day?" Lu Wan complained softly to Bai Yonghui beside him. The two of them were sitting in the corner of the office, far away from other people.
A municipal bureau chief had to attend every murder case, which put a lot of pressure on Lu Wan.
Bai Yonghui lowered his voice and said: "The deceased Qu Hailong is not a local. He represents high-quality foreign entrepreneurs. The superiors are very concerned about this case."
This case currently looks very much like a vendetta. The enemy may have committed the murder himself or hired a murderer. At least according to the clues currently available, Lu Wan prefers professional killers to kill.
As long as it is classified as a vendetta, this case will be very troublesome. If an entrepreneur from out of town is killed in a vendetta, if the murderer is a local, it will be a serious blow to the image of Meihai City.
Lu Wan also understood the situation immediately and asked Qin Youwei to start reporting on the autopsy.
"The two deceased persons were Qu Hailong and Wang Qian. They were a couple and lived in Room 2501, Building 5, Xiangshan Community. There were two crime scenes, namely Qu Hailong's car on the second floor of the underground parking lot and in Room 2501. Living room." Qin Youwei said while switching photos on the big screen.
"Qu Hailong's time of death was between 12:00 and 12:30 this morning. The cause of death was a fractured skull. Based on the wound on the back of his head, it can be determined that it was a murder weapon such as an axe." Qin Youwei specially prepared a picture of an axe. photo.
Qin Youwei also found impact injuries on the deceased's cerebellum. There were no defensive wounds on the deceased's body, which shows that he had no ability to fight back when he was killed. In addition, the deceased had a high alcohol concentration in his body and was in a drunken state when he was killed.
"The murder scene I restored is roughly like this." Qin Youwei said, "The murderer suddenly attacked Qu Hailong from behind after he got out of the car, knocked him unconscious, dragged him back to the car, and then walked around to the passenger seat. Swinging an ax to commit murder.
The spray of blood in the car was very irregular. The murderer should have put a layer of something on it when he used the ax to chop people. It is not possible to determine what it was for the time being. "
Sun Xiaokai added, "I found out that Qu Hailong spent money at a hotel in Shangcheng District last night, and then called a driver. I have contacted the driver, and the time he sent Qu Hailong back was 12:03 in the morning.
After arriving at the entrance of the parking lot, Qu Hailong insisted on driving himself and asked the driver to go back. This phenomenon is very common among the driver, and the driver directly agreed to his request. "
The driver did not enter the underground parking lot, and the line was completely disconnected.
At this time, Qin Youwei suddenly said: "There is another very strange place."
The screen on the big screen switched, and a report full of data appeared in everyone's field of vision.
"I found a component of industrial oil on Qu Hailong's wound. It has been determined to be the protective oil applied on some tools when they leave the factory. For example, the screwdriver you use, you will find oil on the surface when you first buy it." Qin Youwei explain.
"Did you buy that ax new?" Zeng Hao's tone was full of surprise.
Not only Zeng Hao, but everyone present was shocked.
I recently purchased an axe, which is a very pointed direction for investigation.
The murderer knew the layout of Xiangshan Community, Qu Hailong's parking space, the time he returned home, the fingerprint lock and surveillance at his home. It was obvious that after a long-term investigation, he should be a local.
Nowadays, there are not many people who suddenly buy axes. Even with the addition of online channels, as long as the police are given enough time, they will definitely be able to find everyone who buys axes.
This was a premeditated murder. Whether it was the method or route of committing the crime, the murderer had carefully considered it. Why was such a rigorous person so careless when choosing the murder weapon?
Everyone knows that Lu Wan suspects that a professional killer did it. Professional killers would never commit such a serious mistake.
Lu Wan didn't pay attention to the hesitant looks in everyone's eyes and said to Qin Youwei: "Continue!"
Next is Wang Qian’s autopsy report.
The cause of death of Wang Qian was the same as that of Qu Hailong. He was killed with the same axe. The murderer also had something on his head when he was killed. The time of death was between 1 a.m. and 1:30 a.m., consistent with the time the murderer appeared under surveillance.
There were bruises on the back of Wang Qian's head and scratches on her arms. Qin Youwei extracted Wang Qian's skin tissue from the floor of the master bedroom.
According to this point of view, Wang Qian was in the master bedroom when the murderer entered room 2501. Then the murderer entered the master bedroom, knocked Wang Qian unconscious, and dragged her to the living room before committing the murder.
"According to your speculation at the scene, the murderer raised the fence of the master bedroom, right?" Qin Youwei looked at Lu Wan.
Lu Wan nodded, "Any questions?"
"How should I put it?" Qin Youwei smacked his lips, "He killed Wang Qian with an axe. He must have been wearing gloves at the time. I found blood stains on the handrail behind the door but no fingerprints. After DNA comparison, the two There was blood from the dead.
However, I did not find any blood stains on the master bedroom fence or door handle, and there was no blood stain on the handle outside the door, so the murderer may have worn two pairs of gloves, one for committing the crime and one for moving around the building. "
Chen Xiaoxiao said thoughtfully: "It stands to reason that he should raise the fence and close the door after killing, otherwise there would be blood stains. Unless he changed his gloves after killing and then touched the fence and the master bedroom door, but that way there won’t be blood stains on the handle behind the door, unless he replaces it again?”
This behavior sounds very unreasonable.
Chen Xiaoxiao's expression gradually became shocked, "So what you mean is... he didn't kill Wang Qian directly after dragging him out. Instead, he came back and raised the fence first, then went out and changed his gloves to kill, and then leave?"
Lu Wan nodded in agreement. Chen Xiaoxiao's analysis was very reasonable, but Lu Wan's expression became more solemn.
From the analysis of the murderer's behavior, he was particularly concerned about the child's feelings and was afraid that the child would be frightened, so he put a cushion under Wang Qian's head to prevent her from making any noise.
He raised the fence to worry about the children coming out. Not only was he considering the safety of the children, but he also didn't want the children to see the scene of his mother's tragic death.
Thinking about the newly bought ax again, Lu Wan felt that her brain was about to shut down.
Zeng Hao expressed Lu Wan's thoughts with a rude word, "Is this still a professional killer?"
"It should be very professional, right?" Peng Yuetao stood up to express his opinion. He came to the whiteboard and simply drew a schematic diagram of Building 5 on it.
Peng Yuetao is the force support of the police force. He has worked in the SWAT team before and is good at various offensive and defensive battles.
"I have deduced the murderer's entire murder route, and now I will connect it together for you. In this way, you should be able to feel how professional he is." Peng Yuetao began his own deduction.
In the morning, Peng Yuetao checked the surveillance of the underground parking lot and found several routes that could avoid the surveillance and leave the parking lot. Then Peng Yuetao contacted the owners based on the parking space numbers and retrieved their driving recorders. No murderer was found.
After screening the surveillance in the building, it was basically determined that the murderer entered from the underground parking lot, but the murderer perfectly avoided all the driving recorders. This is not a coincidence, but the murderer deliberately avoided it.
After successfully reaching the stone pillar behind Qu Hailong's parking space, the murderer began to wait there. He had done some research in advance and knew that Qu Hailong would be back very late tonight.
After Qu Hailong drove back, he was not in a hurry to take action. You must know that Qu Hailong needed to reverse the car into the garage. At that time, the reversing image and reversing mirror could allow him to see the situation behind him, but he did not find the murderer.
This may be related to Qu Hailong being drunk, but Peng Yuetao believes that the murderer took into account the reversing image and reversing mirror and avoided Qu Hailong by walking around the stone pillars.
After killing Qu Hailong, the murderer first took away the driving recorder, and then used Qu Hailong's hand to unlock the phone while keeping the phone from being locked. He needed to use the phone to open the door lock. At the same time, he also carefully checked the contents of Qu Hailong's home. There is no monitoring.
However, during the surveillance in the stairwell, no one found the murderer operating the mobile phone, indicating that the murderer had thought of a way to unlock the screen of the mobile phone in advance.
This method is indeed very simple, such as playing a video for a long time, but the murderer can take it into consideration, which shows how careful his plan is.
Then he prepared the ring rope to leave on the second floor, went upstairs to kill people, and then left Building 5 through the second-floor window. After that, he perfectly avoided the surveillance in the community and left the community.
After Peng Yuetao said this, everyone's doubts were dispelled a lot.
No time was wasted in the entire murder process, which required not only preliminary investigation, but also corresponding planning.
"I don't think most people can do this." Peng Yuetao took a deep breath, "So I think the murderer is a professional killer."
