The night has not yet fully fallen, but the neon lights in the playground are ready for joyful emotions. Pen, fun, pavilion www. biquge。 info everywhere, so that the men and women in it feel like they are in a dream country.

In the warm lights, a few red and blue flashes are particularly eye-catching.

It is the headlight of a police car.

A lawn not far from the police car was fenced off by a fence, the lawn extended from the green wall in the northwest corner of the playground, and a pale hand poked out of the green wall composed of cypress trees on the 5th and 6th floors.

The bushes were very dense, and the female corpse was erected by the branches in a half-leaning standing position.

The first reaction of Xu Xinger, the head of the forensic medical department, was to look at the neck of the deceased, he held a flashlight in one hand and lifted the deceased's chin with the other, and a purple strangulation mark was clearly visible, about 8 mm wide, very symmetrical.

"The exact same strangulation marks should be the same person as the murderers in the previous two playground murders." Wu Xinger came to a conclusion.

Wu Cuo, the head of the criminal investigation team, was anxious and angry, and said to the young criminal policeman who was leaning on the hood of the police car and looking through the case file: "The third one! ”

"Oh." The young detective didn't raise his head.

He had wheat-colored skin, a cleanly shaved beard, a neat flat head, and looked no more than 25 years old, like a recent graduate, but he had a kind of self-confidence that school boys never had. The cuffs of the shirt are rolled up, the arms are thin, and the whole person looks tall.

He smoked a cigarette, his left eye slightly narrowed to avoid the smoke reaching his eyes, and his long eyelashes seemed to add a soft filter to the scrutinizing gaze.

Xu Xinger continued to conduct a preliminary examination of the corpse, "The temperature of the corpse almost did not begin to drop, and it was less than one hour after death. ”

This conclusion attracted Wu Cuo's attention, and he immediately said to the criminal police on the side: "Block all the entrances and exits of the playground, the murderer may not have left yet!" Retrieve all the surveillance of the playground, check from the surveillance near the scene, and report immediately to anyone who finds it. ”

"Yes!"

The cold light of the flashlight hit the deceased's skin, becoming more and more pale, and soon, Xu Xinger found a bleeding on the strangulation marks, and near the bleeding site, he carefully pinched a thin black wire with tweezers.

Putting the thin thread into the evidence bag, Xu Xinger said to the assistant beside him: "This is the fiber that fell from the rope of the strangled deceased, and it was immediately sent to the laboratory department to confirm the material of the rope, and the body was transported back for autopsy overnight tonight." ”

The evidence bag was stopped by the young detective who was going through the case. The young criminal policeman approached the evidence bag, only glanced at it and said: "Shoelaces, the most common canvas shoe laces, the murderer is not stupid, he knows to choose a murder weapon that can be easily taken away." Nylon material, good toughness, and enough length, the only problem is that it is too fine. ”

As soon as the young detective spoke, he immediately attracted Wu Cuo's attention. Anyone who knows the young detective knows that few criminals can get praise from him for being "not stupid".

Wu Cuo walked up to the young detective and asked, "Too fine?" What do you mean? ”

"It's too thin, so the force area is very small when the neck is strangled, and the smaller the force area, the greater the pressure, and the skin at the strangulation marks is worn out. The same is true for murderers, strangled a person with such a thin shoelace, and the hand is likely to be worn out...... However, this is already his third crime, he will definitely wear gloves, what kind of gloves will young people choose? ”

"Wait," Wu Cuo interrupted, "It doesn't have to be a young man. ”

"Not only young people, but also minors, and moreover, there is more than one murderer, it should be ...... Three minors committed the crime together. "Judging from the autopsy results of the first two deceased, in addition to the fatal strangulation marks that led to mechanical asphyxiation, there were also restraint injuries of varying degrees on the deceased's body, such as bruises on the outside of the ankle and calf, indicating that someone was holding or holding the deceased's calf, and there were obvious scratches on the arm, indicating that someone tried to grab the deceased's arm to stop the deceased from struggling." In short, it was the three different people who strangled them, pressed their legs, and pinched their arms. ”

"It is also possible that the deceased had a fight with the murderer, and these scars were left during the fight, but the deceased lost the fight and was eventually strangled by the murderer." Wu retorted.

The young criminal policeman looked left and right, suddenly walked out of the cordon, ran along the cement road in front of the grass for about 30 meters, turned a corner, and disappeared in Wu Cuo's sight, and after a while, a shout came from the direction where the man disappeared.

"Wu is wrong for your uncle!"

There was only one voice, but everyone heard it very clearly.

"Do you hear that?" The young detective asked as he ran back.

The black line on Wu's head is the answer.

The young detective pursed his lips and smiled, and continued: "The murder site chosen by the murderer looks remote, just because the turns and trees on both sides block the view, in fact, the nearest amusement facility is less than 30 meters away, but the staff in charge of the amusement facility did not hear any abnormal sounds, what does this mean?" ”

"It means that the victim was subdued as soon as possible, and she couldn't call for help at all."

"While justice sometimes comes a little later, it will not be absent." The young criminal policeman pointed at Wu Cuo and said, "IQ is the same." ”

I don't know if Wu Cuo's temper is too good or if he has been used to it, he just motioned to the young criminal policeman to continue.

"Of all the injuries on the victim's body, the only one that can make her lose her ability to call for help is the neck of the victim, and the murderer must have strangled the victim's neck in the first place.

There is no doubt that the action of strangulation requires two hands to complete, and it is impossible for the murderer to leave binding wounds on the victim's legs and arms while strangling the neck, so there is only one possibility, that is, the murderer also has two helpers, and while he is strangling, one of the two helpers holds the victim's legs, and the other controls the victim's hands. ”

The young criminal policeman paced back and forth as he spoke, and after speaking, he happened to pace in front of Wu Cuo, and raised his eyebrows, which clearly meant "You mortals, is there anything you don't understand?" ”

"Ahem," Wu Cuo lowered his head and thought for a while, "How do you know that the murderer is a minor?" ”

"Just because the restraint wounds on the victim's body are relatively shallow, it is not certain that the murderer must be a minor," the young detective's gaze suddenly became sharp, and he glanced around the crowd of onlookers, "However, since the murderer has the courage to come back and watch, I will reluctantly find them out." ”

There was a commotion in the crowd, and three boys aged 14 and 5 immediately broke through the crowd and fled as soon as they met the eyes of the young detective.

"Catch them!" Wu Cuo was the first to run out, and before he could catch up on the corner, he knocked down a boy.

"Running so fast, it deserves to be Chen Rabbit." The man closed the case file, leaned against the police car and lit a cigarette.

Before a cigarette could be smoked, all three suspects were arrested, wearing cycling gloves, and one of the boys was wearing black canvas shoes with black laces.

The boy's face was arrogant and disdainful, even though he was handcuffed and controlled by two criminal policemen, he tried to jump up and kick Wu Cuo, who grabbed him, and shouted uncleanly: "Dare to move Lao Tzu!" You're fucking tired! My dad is Li Qiang! ”

Li Qiang.

Although the name repetition rate was extremely high, all the police officers present still muttered in their hearts.

The director of the Municipal Public Security Department also happens to be called by this name.

"Be honest!"

Wu Cuo grabbed the boy's feet and wanted to kick people, took off the shoes on his feet, glanced at the shoelaces, and threw them to Xu Xinger, "It's this one, there are undried blood stains on the shoelaces." ”

Xu Xinger put the shoes into the evidence bag and "immediately brought them back for inspection." ”
