Everyone came to the stairwell between the 5th and 6th floors. Xu Tiannan said to Wen Sibao: "After a while, you imitate the actions of the Du detachment when they went upstairs."
After Wen Sibao was ready, Xu Tiannan asked Li Mengxue to go down from the sixth floor. When she and Wen Sibao were about to meet face to face, Xu Tiannan suddenly tripped Li Mengxue.
"ah!"
Li Mengxue screamed in surprise, and since she was going downstairs, she fell down the stairs after being tripped by the opponent.
Seeing this, Wen Sibao quickly supported the other person with quick eyes and hands, and Xu Tiannan immediately stepped forward to stop the two of them. Only then did everyone realize that Li Mengxue's left hand happened to be grabbing Wen Sibao's right forearm.
Xu Tiannan explained.
——"This is the scene at the crime scene. At that time, the Du detachment was going upstairs. The female executioner No. 3 pretended to come down from the stairs. After pretending to fall, the Du detachment immediately moved her hands to support her out of conditioned reflex.
other side."
——"And the other party took this opportunity to prick Du's hand with a sharp needle on his middle finger ring."
——"But this ring is not an ordinary ring. I suspect that there is some kind of drug that can quickly cause paralysis hidden inside."
——"So after being injected with anesthetic in Du Yongzhi's hands, he immediately became alert."
——"At the same moment, Female Executioner No. 3 hit the electric shock baton that had been hidden in her left hand in advance, but the anesthetic had not spread to the body at this time, so the Du detachment used her right hand to force the executioner on the premise that she still had the ability to move.
It was only by resisting this electric shock that the electric shock wound was left on the palm."
——"This is why there are blood spots on the tiger's mouth of Team Du's left hand and an electric shock wound on the palm of his right hand."
After hearing the above explanation, Wen Sibao immediately asked: "What you said is probably correct, but this is just a personal speculation. Why are you so sure that the executioner at that time must be a woman, and she must have poisoned the needle?"
Where is the ring on the middle finger?”
Xu Tiannan turned on the flashlight and shined it on the wall next to the people. It was an old white latex paint wall, but there was a clear handprint on the dirty wall, which was nearly 30cm long.
length distance.
Xu Tiannan explained.
——"This is a wipe-type palm print. The wall around the palm print is covered with dust, but only the wall where the palm print passes is very clean."
——"So I judge that this is a palm print that was left recently. The situation at that time should be that when the Du detachment was still awake, they immediately fought back against the murderer. At the moment when the murderer was pushed down, the palm of his right hand was also inadvertently
I scratched this wall, so I drew this palm print mark of about 30cm on the dusty wall."
——"Based on the front end of the palm print, it can be seen that the murderer was wearing gloves at the time. Although the fingerprints cannot be obtained, it can still be seen that the five fingers of the gloves are very thin and should be the fingers of a woman."
"Look here again." Xu Tiannan pointed to the middle finger position of the palm print on the wall. Just on the center line of this position, a very thin scratch was made."
——"Based on this scratch, it can be judged that the murderer should have been wearing a pair of women's gloves and a ring with an anesthetic needle on her middle finger. When she was pushed down by the Du detachment, her right hand instinctively supported her.
The ring was scratched on the wall, so the needle worn on the ring would scratch the wall, leaving such a mark."
——"But even the most powerful anesthetic needle has a process of taking effect. And you just learned from the residents in the unit that two residents heard the noise in a short period of time, but the sound disappeared soon.
This also shows that Du Yongzhi resisted the murderer for several seconds before the anesthesia injection took effect."
——"At the same time, Du's weight is about 80kg. Putting a rope around his neck and throwing him out of the window is obviously not something a woman can accomplish, so there is at least another executioner present tonight.
"
After talking about the above questions, Xu Tiannan finally explained: "That night, Du's detachment encountered a power outage when he went home alone, but when he helped a woman who fell, he was attacked by the other party. He should not have been trained like this
He was easily subdued by the opponent, but the anesthetic and electric shock baton caused him to lose most of his fighting ability, which led to him being thrown out with a rope around his neck."
The scene has been roughly restored. Although more than 2 hours have passed since the incident, the task force still notified the police officers on duty at various intersections at night to pay extra attention to a man who is about 1.9 meters tall and wearing a
A man in a black woolen windbreaker and a woman about 1.62 meters tall and wearing gloves.
Unexpectedly, in less than 10 minutes, a piece of unexpected news came from the police station. In an alleyway 800 meters away from the crime scene, someone called the police and reported that a male body was found.
's corpse.
When everyone arrived, they found the man dead at an intersection of the alley. He was wearing a black woolen coat and had a strong build, but his body was covered with more than thirty stab wounds.
However, the most surprising thing is that the face of this male corpse has been splashed with sulfuric acid. By the time everyone arrived, it was completely disfigured, with no trace of its original appearance.
Li Mengxue immediately took out his toolbox to conduct an on-site inspection of the body, and finally concluded that although the appearance of the deceased could no longer be determined, judging from the black woolen coat, height, weight and shoe size of the deceased, there was a high probability that he was the same person today.
The executioner No. 2 who assassinated Du Yongzhi late at night was a strong man.
From this we can judge that in tonight's assassination of Du Yongzhi, at least strong man No. 2 and woman No. 3 participated in the action. However, after they left the scene, they encountered a certain situation that led to the execution of No. 2.
He died here.
Wen Sibao looked at the melted flesh on the other person's face and said to himself: "Who killed him? Why did he have to disfigure him?"
Xu Tiannan didn't answer. He just turned on the light and checked along the walls on both sides of the alleyway. Then, after checking on the deceased, he called everyone over and pointed to some small but deep scratches on the wall and analyzed.
.
——"On the walls on both sides of this alleyway, there were several marks made with daggers. These marks were very similar to the knife wounds on the deceased's body. They should have been left during the struggle of the deceased."
——"But these marks on the wall only stopped at the position of the deceased. In my opinion, this is more like the deceased chose to stay here to block the killer's advance in order to protect his companions from retreating."
——"The murderer is a master of knife use, his technique is clean and neat, and he can cause several fatal injuries to the deceased in a short battle."
——"But the deceased fought the opponent with bare hands, and his fingernails and fist bones were intact. This shows that the opponent's killer was not only strong in swordsmanship, but also more agile behind his back. He was not hit by the opponent in this fight.
"
After listening to the above analysis, Wen Sibao asked: "Then why does the killer have to disfigure the other person after killing him?"
Xu Tiannan said: "There is only one possibility. The killer does not want the police to see this man's face."
"Why?"
Xu Tiannan thought for a while and explained.
——"I have a bold guess. Maybe Executioner No. 2 is someone our police know. Once this person is found, we can follow the clues to find the other three executioners."
——"However, the killer had some purpose. He did not want the remaining three executioners to be caught by the police. The reason is that the executioners must have something in their hands that the killer did not want us to see."
——"So I think that the executioner must have criminal evidence of this killer, or criminal evidence of the boss behind hiring this killer."
After Xu Tiannan finished speaking, he said to everyone: "The deceased was at a crossroads. From here, the alleyway divided into three forked roads. Everyone was divided into three groups and inspected along the alleyway."
Soon, Zheng Jianghu found an anomaly in a fork in the road more than ten meters away.
"Here's a drop of blood!"
Xu Tiannan and others rushed over immediately and found a drop of blood in the soil on the side of the road. They explained: "It's true. Executioner No. 2 is protecting this person. It is most likely the woman who participated in the killing of the Du detachment tonight."
The murderer, she's injured and shouldn't be able to run far."
So everyone continued to search in the direction of the fork in the road, and finally found a large amount of blood stains in a flower bed one kilometer away, and there were also traces of people lying on the grass.
"Great!" Wen Sibao couldn't help but excitedly said: "As long as we determine that the blood stains along the way come from the same person, plus the executioner No. 2 just now, we can confirm the DNA of at least two people in their team. This pair
