I caught the murderer

Today's sunshine is particularly sunny, a rare good weather in winter, but the atmosphere in Yude Middle School is the opposite of it.

Yude Middle School is a school where middle school and high school are read together. In recent years, the pressure of the college entrance examination has been increasing for students. Even the Saturdays of freshmen in senior high school are filled with self-study.

However, the daily remedial classes of Yude Middle School were completely disrupted by a dead body that suddenly appeared today.

The bloody classroom broke into people's eyes unexpectedly when everyone was unprepared, and immediately caused a riot mixed with screaming and vomiting.

Fortunately, when the special case team arrived at the scene, the parents and students on the scene had been evacuated by the school staff, and there was only a woman in formal attire and looking very serious outside the classroom waiting to receive the special case team.

"Hello, Shen Zheng from the special case team." Shen Zheng took out his ID and refused the woman's greetings, "We need to take a look at the scene first."

After saying that, Shen Zheng didn't wait for the woman to respond, and directly stretched out his hand and pushed open the door of Class One and Three.

In the face of the bloody smell coming towards his face, Shen Zheng didn't even frown. He put on shoe covers and gloves and entered the scene. Today's appraisal department is not enough manpower, so Shen Zheng can only go to battle in person.

There was a dead body hanging on the ceiling fan in the middle of the classroom. The dead body was wearing the girls' school uniform of Yude High School, and had long straight black and beautiful hair. It looked like a girl.

The corpse's limbs were hanging down naturally, and her feet were hanging above the desk that was half a person's height. Her wrists were cut into two deep cuts, which is where the blood in the classroom came from.

Shen Zheng walked around the half-dried pool of blood on the ground, and then began to check the wound on the wrist of the deceased.

The wound was small but deep, with neat and smooth margins and sharp corners. It was a typical incision wound. The murderer should have used a sharp-edged knife such as a pocket knife or fruit knife.

After taking pictures of the wound to obtain evidence, Shen Zheng hugged the corpse's leg and laid her flat on a nearby desk. At this time, Pei Yuzhou also stood beside him: "Boy?"

Shen Zheng asked with a question mark on his face: "Boy?"

Pei Yuzhou reached out to push the hair covering the corpse's face away, and gently pulled it upwards, revealing a little brown hair that was different from the black one.

In this way, the deceased's face and Adam's apple were completely exposed. Although his eyeballs and the tip of his tongue protruded slightly, it was not difficult to see that he had a handsome appearance before his death.

"The eyes are good," Shen Zheng boasted, and then he took a closer look at the corpse, "There are bruises and swelling on the face, obvious bleeding spots on the skin, and foamy liquid in the mouth and nose, it should be suffocated."

Pei Yuzhou glanced at the left hand of the deceased: "There are bruises, and there must have been a struggle before death."

Although it is generally difficult to find the scars caused by the struggle on other parts of the deceased's body because of the thick clothes worn in winter, the deceased's school uniform with blue and white as the main tone was covered with a lot of dust, which also supports the homicide from the side. possible.

"Check it out, it must have been homicide." Pei Yuzhou looked at the classroom floor and windows, but did not find any obvious footprints or handprints, "The scene is 'clean' enough."

Shen Zheng had already removed the colorful plastic rope wrapped around the neck of the deceased, and then he found two strangle marks on the neck of the deceased.

A strangle mark is more obvious, the side of the force is deep, and the sides are gradually shallower, showing a "lifting" shape, and finally rising behind the ears and disappearing;

The other one is not so obvious, the strangle marks are uniform and closed, and they surround the neck in a horizontal shape.

The former is caused by the corpse hanging on the ceiling fan, and it is also the iconic scar of hanging; the latter should be caused by human beings, and it is the iconic scar of strangulation.

But this degree of depth is somewhat contradictory to the scratches on the hands of the deceased.

Pei Yuzhou also noticed this: "Maybe it's because the corpse has been hanging for too long. I'll let the forensic room do a detailed appraisal later."

"The rigor has gradually spread to the whole body, and the cornea is slightly cloudy. The time of death should be within [-]-[-] hours."

现在是华国时间09:30，这就说明死者的死亡时间应该在昨晚09:30到今早03:30之间。

Pei Yuzhou continued: "I just asked the woman named Yan Li outside the door. She is the head teacher of Class 08 and 30 of Senior High. According to her, there was evening self-study yesterday, and the students didn't finish school until [-]:[-] in the evening."

"And the security guards didn't find anything wrong when they patrolled and closed the building at nine o'clock, and confirmed that the doors and windows were locked."

When Pei Yuzhou came, he observed that the windows of this building could only be opened from the inside, which meant that either the murderer hid in the building and never left, or the murderer had the key to the teaching building.

The on-site evidence collection was about the same, and the next step was the questioning and evidence collection. Shen Zheng asked as he walked outside: "Where is the door of the classroom?"

"Yan Li said that the door of her class was broken a week ago, and the final review is quite busy recently, and there are no valuables in the classroom, so I haven't had time to change it."

Shen Zheng nodded, took off his gloves and shoe covers, and began to praise Pei Yuzhou every day: "Okay, I asked so many questions in a few minutes."

Ever since he opened up with Pei Yuzhou, Shen Zheng has completely become a "Yuzhou control", changing ways to please Pei Yuzhou every day, and constantly proving from the side that Pei Yuzhou is still the rational, intelligent and self-controlling person Dr. Pei is afraid that the other party will have too much negative emotion due to the withdrawal reaction.

Pei Yuzhou, who was successfully shunned, only had time to smile at Shen Zheng, and Yan Li, who heard her name, came over: "Officer, what do you want me to do?"

"I want you to confirm the identity of the deceased," Shen Zheng switched the camera to the scene just taken, "Is this a student in your class?"

Seeing the slightly ferocious appearance of the deceased, Yan Li furrowed her eyebrows together fiercely: "Yes, his name is Xu Xin, and he is a student in our class."

"Contact his parents." Shen Zheng motioned to the other two police officers who followed them to take the body away, and by the way cordoned off the entire Class [-] and [-] of Senior High School, "What was the personality of the deceased before he was alive? ?”

Yan Li didn't pay attention to Shen Zheng's words at all, she only noticed the cordon on the hands of the two police officers: "Officer Shen, are you going to seal the classroom? Then how can we still go to class?"

The expression on her face was more worried and anxious than when she saw Xu Xin's death, as if a student's life was only a few days' lessons.

Such an attitude made Shen Zheng a little displeased: "Such a murder case of such a bad nature happened, it is inevitable to suspend classes."

"Do you want students to study in such a dangerous school, and then die a few?"

Yan Li's complexion became ugly because of Shen Zheng's not-so-pleasant words. Obviously, she didn't agree with Shen Zheng's statement, but she couldn't refute it due to the identity of the other party.

Pei Yuzhou interjected at the right time: "Only if we solve the case as soon as possible can the school return to normal order, otherwise the parents won't let this matter go easily, will they?"

"So I would like to ask Mr. Yan to cooperate with Xu Xin." Pei Yuzhou paused, "For example, why did he die wearing a woman's attire?"

Faced with Pei Yuzhou who had just chatted with her for a while, Yan Li's attitude was a little better: "I don't know, he is usually a very normal boy, although his grades are not good, but he is very good."

"Don't play Tai Chi with me for the sake of the school's reputation," Shen Zheng said coolly from the side, "To be honest, I'm a human lie detector."

"This……"

One soft and one tough, no matter how good Yan Li's psychological quality is, she can't help being pried open, after all, she is just an ordinary person.

On the other hand, Pei Yuzhou couldn't help but feel his scalp explode when he heard the "humanoid lie detector".

Considering that he was able to deceive the other party so many times, he was really lucky.

"Xu Xin's character is a bit quiet..." Yan Li's tone slowed down a bit, as if she was thinking about how to say it better, "Sometimes he will be called like a girl."

After saying this, Yan Li immediately added: "But he never did such a thing in normal times."

"Our school is a very serious school, and we don't let students come to class in weird clothes."

But Pei Yuzhou's focus is obviously not here: "Said? By who?"

"Is it you or your student? Has anyone ever expressed a strong displeasure with him?"

Dressing a dead male in female attire most of the time represents a strong insult.

Yan Li didn't want the police to focus on her students, so she said in a perfunctory way: "It's just a child's joke. It's not malicious. Everyone is talking about it. It's nothing special."

The continuous negatives proved that the other party was flustered, and Pei Yuzhou squinted his eyes: "So, Mr. Yan, you knew and indulged? It seems that the person who takes the lead must be your favorite student."

"Check it out, the best grades in this class." Pei Yuzhou bypassed Yan Li and said to Shen Zheng, "Since Teacher Yan is so uncooperative, we can only invite you and your students to the police station. "

After strangling people to death and hanging them in the classroom for bloodletting, the murderer must be someone related to Yude Middle School.

And Xu Xin is thin and thin, even his peers may strangle him to death, so the possibility of a student committing the crime is not ruled out.

Yan Li didn't expect that Pei Yuzhou, who was still soft-spoken just now, would suddenly change her face. She was choked and speechless for a moment, looking rather funny.

Shen Zheng coughed feignedly, covering up the smile on the corner of his mouth.

When Pei Yuzhou felt that he could get words out of the other party's mouth by lowering his posture, he was so gentle and gentle; but once he lost interest in the other party, he would turn his back on him faster than turning over a book.

Yan Li is a very ordinary head teacher. Maybe she is very serious and responsible, but judging from her personality, Pei Yuzhou doesn't think she can get along well with the students.

It was obvious that Yan Li only knew a rough idea about the affairs among the students, and she kept it a secret for the sake of the so-called "school's reputation".

And Xu Xin should not be among the students she focused on. Instead of wasting time with her here, Pei Yuzhou might as well go back to the police station and ask Jiang Yue.

Pei Yuzhou pulled Shen Zheng who was giggling aside: "Let's go, let's meet those two kids."

Although most of the students were taken home by their parents, the two students who were the first eyewitnesses at the scene of the crime were still left at the school, waiting for police inquiries.

As a high school student, Pei Yuzhou sighed silently. It seems that this time his candy is considered leucorrhea.
