A few hours later, Coco and Wang Tao confirmed the list of destroyed physical evidence, and then made up for each case one by one. The only thing that can be fortunate is that after the physical evidence is collected, many of the original objects are sealed and protected in the ice storage, although the collected part is destroyed, most of the original objects can be found in the ice storage for re-collection, inspection and result reporting.

But there was only one case that was bad.

Two weeks ago, at half past four in the morning, in an unnamed small hotel near the suburbs, a female college student fell to the ground from the window of her room on the seventh floor. The deceased's name was Zhang Pei, a senior at a nearby university. According to the confessions of the classmates, the night before the incident, nearly 20 of their classmates celebrated the completion of the thesis defense, ate, sang, and drank. No one can remember how Zhang Pei left the team. It was only when the police found the school the next day that they were shocked to learn that overnight, there was actually a yin and a yang.

Xun Keran had also heard of this case, the body was examined by another teacher in the forensic medical class, and the DNA of male sperm was detected from the lower body and oral cavity, and there were two different people, and three crumpled tissues were also collected at the scene in the hotel room, which also confirmed the sperm from two men. In addition, a large amount of alcohol was tested in the blood of the corpse, indicating that Zhang Pei was mostly drunk before his death.

The criminal police officer in charge of the case at that time entered the classroom during the class assembly of the school with the permission of Captain Zheng Longhao, and stated that in order to assist in the investigation of the case, he would take DNA samples from each male classmate, but before he finished speaking, a boy sitting in the penultimate row jumped up and rushed to the back door of the classroom.

Of course, the one standing outside the back door was also a criminal policeman.

In this way, the suspect was directly arrested, Zhang Pei's male classmate Jiang. According to his trembling confession, he and another boy surnamed Meng supported Zhang Pei after singing, seeing that the girl was almost unconscious, so at Meng's suggestion, the two found the nearest small hotel and wanted to open a room for Zhang Pei to rest, because they were too lazy to go back to the dormitory, and by the way, the two also opened another room to rest until dawn. But just as they put Zhang Pei down on the dim bed in the small hotel, the alcohol washed through the two of them, and they thought that Zhang Pei was already so faint that even if she did something, she wouldn't remember it the next morning. So as soon as he grinned and took off his pants, he crossed the line, from a senior to a senior rape suspect.

But just before the second boy was apprehended, the physical evidence came to a conclusion from the fingerprints and other traces on the windowsill: Zhang Pei probably climbed the window and jumped down by himself. The only surveillance probe obtained by the criminal police team also corroborates this statement, the two boys left the small hotel at 1 a.m. in the surveillance, and Zhang Pei fell from the building at 3:55 a.m.

So no matter how the family cried and grabbed the ground to pay for their lives, the objective facts are the same as what the arrested boy said, Zhang Pei's fall has nothing to do with them. The criminal police knew, the forensic evidence knew, and the students in the school who were rumored to be rumored also learned about it from their teachers.

After Jiang was arrested and interrogated, another boy, Meng, has been on the run, and the family said that they didn't know where he was, and the school was helpless, but this embarrassing situation finally ended among young people.

At about 1 o'clock in the morning late at night, Zhang Pei's roommates, who received a "secret report", called on almost all the girls in the class to rush downstairs to the boys' dormitory, directly smashed open the locked ground floor door, and swarmed up to the door of a certain dormitory on the third floor.

"Open the door! We know you've hidden the man surnamed Meng inside! Open the door!!! The girls who took the lead slammed on the door of the men's dormitory over and over again, and they heard that the boy who had absmeded had been seen quietly returning to his dormitory, and the anger that had been silent swirled among the girls, gathering everyone and creating this army that poured out of the night.

The dormitory manager downstairs heard the sound and rushed over, and the doors of several dormitories around him also opened when they heard the sound, but at a glance, the girls occupied the entire floor silently, and no one dared to step forward to stop them, they were not children, and the 23-year-old seniors who were about to graduate had all the combat power of adults. The dormitory manager quietly slipped downstairs again to call the school's security office.

"Open the door!!" Despite the loud knocking, the dormitory door was always closed, "Do you think he's brotherly and righteous to hide?" What about Zhang Pei? If Zhang Pei were your sister and sister, would you let him go with the surname Meng? ”

[Zhang Pei jumped off by herself, and I didn't push her......] There was a low retort from inside the door.

The faces of the girls who heard this changed drastically, and the person who took the lead took out a wad of RMB from his pocket and shouted at each dormitory boy watching in the corridor on the left and right: "Whoever helps smash this door open, this money is the reward." ”

After a few seconds of silence, a tall boy turned around and took out an axe from his dormitory for carpentry practice, and walked all the way to the door where the girls gathered, "I don't want money, you guys step back and beware of touching it." With that, he picked up his axe and began to smash the lock on the door of the dormitory.

"Zhang Pei is the youngest in our dormitory, and he has never blushed with anyone in his four years of college."

Knock –

"She plays a good piano, likes to write calligraphy, and I learned cross-stitch from her."

Knock –

"She's only 22 years old, and she's never had a boyfriend."

Knock –

The rhythmic sound of slamming the door echoed through the hallway with the loud and choked voice of the girl.

"How did you do it? She will graduate in half a month...... She hasn't saved enough money to travel, she hasn't tried Michelin-starred restaurants, and she still has so much to work hard to achieve...... No more...... Jaya...... Nothing! ”

There was a slamming sound on the door, and sweat was dripping from the boy's forehead. Soon, the other boys came over, took the axe from his hand, and continued silently.

The security department rushed up, but was blocked by the other boys in the hallway.

"We're not going to do anything to you, we just want to catch you and hand you over to the police."

The girls' voices still echoed in the hallway.

"We're not you, we're not going to do the same thing."

The people of the Security Section, you look at me, I look at you, and in the end they are all silent.

All that was left in the hallway was the clatter of locks.

Eventually, the door was smashed open, and at the same time as the boys pulled out the suspect boy, the police from the nearby police station also arrived.

The students gritted their teeth and watched the man pass by with a pair of eyes, restraining the hatred caused by the sadness in their hearts, watching as the man surnamed Meng was handed over to the police, and no one touched him from beginning to end.

I don't know which one was the first, but there was a choked cry among the girls, and then the sobbing sound became louder and louder, and finally it turned into a contagious cry......

What if you catch someone, the little sister in the dormitory will never come back.

——————————————

After a series of interrogations and physical evidence tests, the two young boys also admitted that they raped Zhang Pei while he was unconscious, but the tissue ball with **** DNA left by the boy in the physical evidence section in the hotel room was destroyed, because the physical evidence was too small, and the spare part was not divided into the warehouse for storage, so now only the inspection report issued at that time is left, which is likely to be questioned in court.

So on this unknown twilight, this unknown inn welcomed this unwelcome guest.

Xun Keran rarely used police identification to act, because the places she had gone to before were either full of on-site observation peers or unnoticed, allowing her to trespass.

"Why haven't you finished checking yet?" The front desk of the small hotel unhappily dropped the melon seeds in her hand, and was about to open the door of 308 for her, and when she opened the drawer to get the room card, she was stunned, and then swallowed, "I still have to report to our manager." With that, he reached for the landline's microphone.

Coco pressed the phone that had just been lifted, "Did you rent out that room?" ”

“…… Who, who knew that your police were going to investigate? The little girl at the front desk tried her best to make an arrogant momentum, but it was difficult to hide the heartfelt weakness.

Coco didn't plan to talk to her too much, with a faint turn of her eyes, she had already gone upstairs by herself, and the cry of the little girl at the front desk behind her disappeared with the closing of the elevator door.

The door of 308 was at the end of the dimly lit corridor of the hotel, and Coco raised her hand and slammed the door "bang, bang," and took out her own ID, "Police investigate." ”

She heard footsteps inside the door, saw a flash of shadow on the cat's eye, and the people inside had apparently seen the situation outside. But a minute or two passed, and the door of 308 was unprepared to answer. Coco put away the document he was holding, raised it until his hand was sore, and put it down and smiled. You never understand why there are always people in this world who choose to run away from problems when they are confronted, as if the problems will disappear like bubbles.

Xun Keran smiled, turned around and walked away two steps, and then suddenly turned around and kicked hard.

Bang –

The door of the room, which was already unreliable, shook violently twice, and the people inside immediately opened the door and ran out shouting, "What are you doing! I'm going to call the police! ”

"Welcome to the police." Xun Keran spread his hands, "Am I not here?" ”

……

A few minutes later, the domineering and unreasonable Mountain King had already occupied this humble empty room. The guest who was reluctant to open the door just now was clamoring outside the door for the innkeeper to compensate for his mental damage, but the voice quickly disappeared at the end of the corridor, and as for the method of the innkeeper who fooled him, it was not in her consciousness that Xun Keran wanted to think about.

In this small "big bed room", the right hand of the door is not a clean bathroom, and a little bit inside is a bed that almost occupies space, because the relationship between the guests just now seems a little messy, on the left is a narrow tabletop, and the LCD TV hanging on the wall is about 18 inches. Xun Keran stood in this room that could be walked in five steps from beginning to end, and put on disinfectant gloves without hurrying. From the time of the case to the present, although there is a ban from the police, I don't know how many residents have been rented out by the boss. Even if she was optimistic, Coco knew that the chances of finding useful clues again during this inquest were slim, not so much because she didn't give up, but because she was cornered, and there was no other way than to re-inspect this room. Before leaving, she even heard that the lawyers of the two rape suspects were planning to retract their confessions, but somehow she heard the news, and wanted to take the opportunity to change her confession that she had no rape and just sent the female classmate to the hotel room.

Originally, the most powerful judgment on the case was the physical evidence with ****, but now that the physical evidence is gone, the suspect who is about to go to court immediately transformed, and under the instigation of the lawyer, his attitude was rampant like a mosquito in midsummer, "You beat me, hit me, beat me, if I propose to re-examine the physical evidence, you can't even take it." ”

So Xun Keran looked around the small room, silently thinking in his heart that the only belief was to find an electric mosquito swatter that killed them here.

According to common sense, the inquest has been checked inside and out, even if there is residual hair on the table, it must have been cleaned, the sheets and quilt covers must have been changed and washed, Xun Keran lay down at the mouth of the sewer and extracted the residue, in the toilet, under the table and chair cushions, any quirks have not been let go, and it is easy to find, although she got a "physical evidence bag" that looks considerable, but to be honest, Coco herself doesn't think that there will be the evidence she wants in these, most of the things she can find should be left by the guests after the case, Otherwise, the colleagues who inspected the case at that time would have taken it away.

Just as she was struggling with whether to disassemble some equipment to search, the phone in her pocket vibrate.

"Teacher Wang, I'm not lazy." As soon as Coco picked up the phone, he blocked the other party's words first.

"Teacher Xun, you want to cover up." Wang Tao said unhurriedly in the laboratory, and Coco could even hear the sound of him wiping and unpacking potato chips.

"Then let's bet ten yuan and bet that I'm not at the scene of Zhang Pei's case?"

"Well, then you don't have to, I might as well buy more potato chips if I have the ten dollars." Wang Tao actually knew in his heart that Coco was not very good at joking about this kind of thing, so he immediately stepped back.

"Then what's the matter with your phone call?"

"What's the matter......" Wang Tao chewed potato chips on the other end of the phone, and thought for a few seconds before reacting, "Oh yes! Zhang Pei's body was transferred back, didn't you say that you wanted to be re-examined? Eh, why do you say that the colleagues over there would rather fill the building with questions about where the physical evidence is than give you direct contact? ”

Coco pursed her lips with an innocent look, "The last time I transported the corpse was a day late, and I told him to cry when I transported that kid." ”

Wang Tao's sound of chewing potato chips stopped abruptly, and he couldn't react to what he heard for a while, the young man who transported the corpse? That kid who is 1.85 meters full of muscles and dares to sleep with a body bag at night, and dares to go into the cemetery alone in the middle of the night? Was, you, trained, cried, ???

"Wait, I'm sure, maybe we're not thinking the same kid? Maybe you ...... what you said" Before Wang Tao's words were finished, there was a click, but the phone was suddenly cut off, leaving Mr. Wang in a daze, and even forgot to continue eating potato chips.

Coco, who hung up the phone here, was purely because she found something more important than her colleague's phone, and when she was walking around answering the phone, her eyes suddenly fell to the corner behind the toilet, and there was a small section of different white on the white floor tiles, which was a place that normal people would not pay attention to, which means that compared to the obvious physical evidence just now, it is more likely to be something that was negligent in the physical evidence at the time of the crime.

Xun Keran carefully picked up a small cigarette butt from the floor tiles, maybe it meant everything, maybe it was nothing, but at this moment, it was carefully put into the evidence bag.

——————————————

Most of the bodies that fell from a height were miserable, but Zhang Pei's body was unexpectedly intact, perhaps related to her falling to the lower floor, but unfortunately her head hit the ground first, which directly caused serious brain injuries, even if the floor was lower, it couldn't change the ending. Originally, because the physical evidence was conclusive and the examination of the corpse was relatively simple, now Coco could only lie on the corpse inch by inch with a cotton swab to scrape every inch of skin on the corpse, and even all the places in the body and mouth that may leave traces of the suspect, hoping to extract the suspect's DNA from the surface of the skin and supplement it as a strong evidence.

By the time all this was done, the moon had already streaked across the sky, and it was not far from dawn.

Wang Tao had already tilted into a strange angle on the seat next to him, and fell asleep with his mouth wide open.

Coco walked over silently, took a close-up of Wang Tao's face with his mobile phone, and walked away happily.

Walked out of the autopsy room, turned through the lonely corridor, turned on the light and unlocked, and entered the empty test room.

The physical evidence collected in the hotel and the things recovered from Zhang Pei's body were put into the examination and extraction machine, the white analytical instrument made a buzzing sound, and Coco took out the instant cocoa powder in his pocket and made himself a cup of hot cocoa to refresh himself.

At a quarter past three in the morning, the legendary line between night and light, the line between night and silence that obscures all boundaries - Coco remembered that similar words were written in a book I don't know where I saw, and I wanted to laugh a little, at this moment I don't imagine the plot of some horror movie is simply living up to this environment! For example, what kind of human hands appear under the bed, and I don't know the source of the inexplicable sound......

Smack-

As if in response to Coco's thoughts, the lights suddenly disappeared, and the entire laboratory fell into inky silence. Coco was stunned for a moment, cursing her crow's mouth, and was about to get up and fumble for the contact information of the security department, but at that moment, she sensed that something was wrong.

There was the sound of very soft footsteps outside the door.

The darkness froze Xun Keran's movements, and she didn't know whether to touch her phone first or find a place to hide from the situation first......

Click, click-

The very soft push of the door was more pronounced in the quiet darkness, and Coco could hear the rapid beating of her heart in her chest, and she remembered the index fingerprint, the camera that had been installed in her room, and ...... A bombed-up evidence room.

Light streamed in through the hallway, tearing a hole through the pitch-black lab.

Just before Coco clenched his fist and was about to explode, a dark shadow flew out from a corner of the room, rushing like an arrow from a string to the light that had just entered the room.

"Whew-"

"Ahh

The cat's mournful neighing sounded almost at the same time as the man's cry, and the door that had just been opened was closed again, and the sound of hurried footsteps outside the door ran farther and farther away.

It had only been a little more than a minute since the power was cut off, and it took Coco a full minute to react to what had happened.

The door was shut, darkness filled the room again, and Coco exclaimed tentatively, "...... Vegetarian? ”

"Meow~"

"Xun Keran? - Xun Keran? ——”

When Wang Tao re-opened the electric switch and pushed the door into the laboratory, he saw Coco sitting cross-legged on the ground, holding the black cat tightly in his arms.

"Huh? You brought the cat today? Why didn't you see it just now? Wang Tao saw Xun Keran raise his head and squinted at him slightly, "Why do you look at me like this?" What's wrong? ”

Xun Keran stared at him silently with the black cat Susu......

"Oh, it seems to have tripped just now, what, are you afraid of the dark?"

Coco looked at him silently, joking Wang Tao looked relaxed, her heartbeat hadn't returned to normal, did the person who pulled off the electric switch and wanted to enter the laboratory just now know that she was in it, or did she just want to enter the laboratory to do something? Either way, it's likely that this person is the same person who broke into the forensic science department before. But the moment Wang Tao entered the door, she suddenly thought of another possibility that she had never thought of.

This person is Wang Tao.

Assuming so, everything can be explained, why didn't she find out whose fingerprints she sent to the Physical Evidence Division, and the destruction of the Physical Evidence Department made Wang Tao the "most suspicious" person, and the incident just a few minutes is more likely to be directed and acted by Wang Tao, pretending to be asleep, watching Coco be alone, pulling off the electric switch, and then stealing in the dark......

Although he was unwilling, Coco's mind was gradually occupied by this speculation, if all these speculations were true, then Wang Tao's scheming lurking under the surface was really bottomless and terrifying. But the next moment, Coco suddenly gave up all these thoughts, she breathed a sigh of relief and walked towards Wang Tao, "Did you see anyone when you first came over?" ”

"People? When you say power outage? …… Oh, I met a security guard who came to check the electric switch, and said to go down and find someone to help, and I looked at it myself, and it just tripped, so just push it up......"

"Teacher Wang." Coco had a complicated expression.

"Huh? What's wrong? ”

"Don't you know that the people in the security department patrol in pairs of two or three, and they are never left alone?"

Wang Tao was stunned by this sentence, "What do you mean?" ”

Coco told Wang Tao what had just happened to Wang Tao as it was. Listening to it, Wang Tao's face turned white, "You mean I just passed by with the guy in the explosive evidence room?" Also, said a few words? ”

"yes, think for yourself, can you recognize that voice?"

"No...... I ......" Wang Tao snorted, he felt that he had just passed by the shark unconsciously in the deep sea where he couldn't see his fingers, and the horror that he realized afterwards made him break out in a cold sweat. "I really don't know, I woke up and saw that the lights weren't on, so I came out and called your name, and then walked to the corridor and saw a figure, vaguely the clothes of the security department, so I shouted what's wrong, he said the electric brake problem, go down to find someone to fix it...... Then I went down, and I went to see the switch, and it tripped...... Pull it up, and then come to you...... That voice is really an ordinary man's voice. Wait、Why didn't you say it when you walked in the door? Otherwise, Lao Tzu can still chase it in time, maybe he can catch the bastard! Wang Tao muttered to himself for a long time, and suddenly slapped his thigh.

"I didn't say it because I doubted you." Coco said.

Wang Tao was stunned again, what did you say? I didn't hear that clearly.

Coco turned to look at him, "I just suspected that person was you, and I suspected that you were the rat poop in the bureau, and deliberately destroyed the Physical Evidence Department to erase my suspicion." Just before Wang Tao was about to get angry, he added, "But now I know it's not you." ”

"Uh...... Well? The routine turned too fast, and Mr. Wang, who is usually dedicated to studying technology, was about to crash in his brain, "Why?" ”

Coco smiled meaningfully, "Because Susu likes you." ”

Just now, when Coco was about to quietly take out the scalpel, Su Su jumped and ran to Wang Tao's feet with a kitten step, rubbed Wang Tao's trouser leg twice, stretched out his paws and climbed up along Wang Tao's trouser leg, and finally stepped directly on Teacher Wang's shoulder.

I don't believe in you, but my cat believes in you. King Coco stared at Wang Tao and announced.

Thank you, Wang Tao grabbed Su Su on his shoulder, thank you King Mao for not killing, tears flowed.

Su Su meowed, stretched out his flesh paws and stepped on Wang Tao's face and patted it.

Kneel down, little king.

The analyzer over there made a didi prompt sound, and the analyzer that "ate" a bunch of physical evidence materials spit out many report papers in a row, Wang Tao picked up one but didn't have time to care about the next one, and the report paper that flew out for a while made him scramble.

"How much stuff did you stuff into it...... Eh, there it is! This one says that this tissue ball matches the DNA of the first kid caught! So that there is no problem in supplementing the evidence...... Eh, I see, it seems to be ...... Oops, no other kid. Wang Tao said and found that Xun Keran was standing next to him and had been silent, holding one of the report papers in his hand, squinting his eyes, as if deducing something in his mind, people couldn't help but lean their heads over: What, what are you looking at?

Coco pushed away Mr. Wang's approaching head, "The cigarette butt found in the toilet has DNA on it from a man who is related to Zhang Pei. ”
