On April 4, the Changping District Bureau of City C received a report. In view of the seriousness of the case, its bad nature and great social impact, it was reported to the Municipal Bureau of City C.

宋玉诚以及C局的法医给出了如下意见：1.死者的外伤主要位于下身，为锐器割裂伤。2.死者的主要死因主要是断裂生殖器阻塞喉管所引起的机械性窒息，失血性休克以及疼痛不是主要死因。3.根据尸表以及解剖检验，死者的死亡时间是4月22日晚上11点左右。

Analysis of the nature of the case: According to the traces left at the scene and the autopsy, the deceased committed homicide.After preliminary inspection, no traces of struggle were found at the scene of the crime.The murderer's motive for killing the victim still needs further investigation.

Another familiar project meeting.

Song Yucheng finished the report in a cold and flat voice, like an emotionless AI.The atmosphere was so dull that it seemed to freeze, everyone was like a group of fish crowded in a small bucket, feeling suffocated because it was difficult to absorb oxygen.

Diao Shuzhen looked at the dossier in front of him with sharp eyes, as if he wanted to dig out every one of them and read them carefully.

According to the staff on duty at Hongxing Middle School, on the night of the incident, no abnormalities were found in the school.When asked if it was found that there were teachers and students entering and leaving the school gate that night, the security office gave a negative answer.

According to the on-site investigation and visits, the props used to bind the deceased were purchased by the deceased at a nearby hardware store.The origin of the mouthball is unknown.

Due to the poor quality of the carrying object, no valuable footprints, fingerprints, blood, etc. were left at the scene, and no murder weapon used to castrate Zhao Guohua was found.The school's fence is only 1.5 meters. After climbing over from any point, there are traffic roads extending in all directions outside. It is impossible to confirm which direction the murderer left after killing Zhao Guohua.

It is speculated that the murderer was hiding in a corner of the campus. After all the teachers and students left at night, he lured Zhao Guohua, who had returned late, to the construction site and killed him.

In the case of extremely limited physical evidence at the scene, guessing the murderer's motive for killing is a very valuable thing for detection.

Everyone in the task force put forward various guesses.

Hao Ren said: "In my opinion, this matter is really evil. Let me tell you, Zhao Guohua was alone at school at night, and a fugitive kidnapped him to the playground, threatened and lured him, trying to extract the bank card password from him. An intellectual like Zhao Guohua, who looked tall and big, unexpectedly turned out to be a pustules, maybe the murderer's bones would soften as soon as he took out the knife, and obediently followed him to the construction site, but he still died in the end."

Another investigator frowned and said exaggeratedly: "It's hard to say, Zhao Guohua has won a lot of honors, and he is very popular. Maybe he has offended someone who doesn't know it. This psychopathic murderer is not enough to kill people, and Zhao Guohua has to be killed." Lost face."

There are different opinions and discussions.

Indeed, from any angle, this matter is weird enough.

Diao Shuzhen rubbed the physical evidence in his hand, frowning deeply, without saying a word.

During this period, everyone in the task force has put forward the following ideas.

[-]. The murderer may be a colleague of Zhao Guohua, who was jealous of the deceased being repeatedly rated as an excellent teacher, so he took revenge and murdered.The murderer used some secrets or handles of the deceased to coerce the victim to the playground, and finally killed the victim.At the same time, in order to discredit the reputation of the deceased, he resorted to cruel methods on the corpse.

[-]. The murderer was an acquaintance of the deceased, who may be sexually weak or sexually dysfunctional, thin and introverted.The deceased may have taken away his wife or girlfriend, held a grudge, and killed the deceased by castration.While venting anger, it can also ruin the reputation of the deceased.

[-]. The murderer is a fugitive criminal who is purely seeking money, killing people to silence him.

"Xiao Diao, what do you think?" After the discussion came to an end, the director did not forget the silent Diao Shuzhen.

"I don't have any ideas for the time being." Diao Shuzhen shook his head, and the meeting room fell silent. Everyone looked at her in anticipation or unremittingly. "I don't think it's a problem for everyone to suggest that the murderer was to vent their anger and insult the deceased. But the scene at the scene It's not like simple coercion, I suspect that Zhao Guohua voluntarily cooperated with the murderer—"

"It's nonsense." Hao Ren turned his nose up and rolled his eyes, "There is nothing wrong with the surname Zhao, how could he obediently let others tie him up?"

"Look, the steel rings and steel pipes that appeared at the scene were all proved by the owner of the nearby hardware store to be purchased by the deceased Zhao Guohua one after another. If you were the murderer, you would not prepare props to restrain the deceased to prevent the deceased from resisting. Is it reasonable to need to take it from the dead? That's one."

"Secondly, there is a detail that I think everyone has overlooked, that is, why is there medical tape wrapped around the rim?" Diao Shuzhen asked rhetorically.

Everyone looked at each other with confused expressions.

"After the on-site inspection, I went to a nearby hardware store to buy the same steel ring." Diao Shuzhen raised his hand, "Its edge is very sharp, and if it is put on the hand, it will scratch the skin. After the tape is wrapped, there will be no such problem."

"So, since all the props were prepared by the deceased, and the problem of protecting the skin when being tied was taken into consideration. Then, it is likely that this is not the first time that the deceased was tied up, and that day he voluntarily cooperated with the murderer and went to the back of the school voluntarily. On an abandoned construction site."

"If the deceased was not coerced by the murderer, but voluntarily cooperated with the murderer... Then, what were they doing at the scene? I can't figure this out for the time being. However, looking at those suggestive things, it seems that I can guess to some."

I have to say that Diao Shu's guess is really reasonable, and he can explain some unreasonable problems on the scene.For example, the source of the steel ring in the dead man's hand, the suggestive mouth ball, and the way the murderer destroyed the dead body.

"Let's investigate one by one, starting with those who have conflicts and competitions with the deceased." The director frowned and gave instructions.

The case is in a fog, it is not clear.

If it is really as Diao Shuzhen said, then the case will become more complicated:

1. Who is the murderer?How did he or she gain Zhao Guohua's trust and make the victim cooperate with him automatically?

2. How did this thrilling game turn into a brutal and bloody murder scene? What happened?Did the murderer kill with passion, or did he premeditate?

After the project meeting ended, everyone dragged their tired bodies and left one after another, with heavy steps and heavy thoughts.

Diao Shuzhen rubbed his tired eyes, and stopped Song Yucheng, who was holding a large stack of materials in his arms.

"Do me a favor." Diao Shuzhen's eyes lit up when he saw Song Yucheng, "Let's replay the incident tonight."

Song Yucheng raised his upper eyelid slightly, a little surprised, then nodded in agreement.

After dinner, the two went to the hardware store together to buy wrenches, steel pipes and steel rings, and wrapped them up according to the scene of the crime.

Diao Shuzhen packed up the props, and gave Song Yucheng a wink, "Yucheng, we're still short of mouth balls."

Song Yucheng lowered his head, his pretty face flushed slightly, and his voice was no longer cold as before: "Of course you bought it, you have rich experience. Isn't it called One Thousand and One Nights, and every night is different?"

As a forensic doctor, Song Yucheng can look at the anatomy of male and female genital organs in an expressionless and extremely objective manner.However, talking about these things in front of Diao Shuzhen is really embarrassing.

Her jade-like face was dyed with a faint blush, and the jade ring was extremely bright.

Diao Shuzhen said relentlessly: "It is because you have no experience that you are asked to experience life."

When they reached the storefront decorated with neon lights, Song Yucheng was stunned for a moment, and Diao Shuzhen pushed her in.Song Yucheng didn't let go, and even dragged Diao Shuzhen in together.

The shop owner is a beautiful young lady who looks at them with a smile.

Diao Shuzhen wandered around, curiously taking out various supplies to look at.

Song Yucheng was at a loss and stayed where he was.

"Is that your girlfriend?" the shop owner asked.

"Ah?" Song Yucheng was stunned for a moment, double pupil glanced at Diao Shuzhen's back, his deep eyes were filled with unknown emotions, "No."

"That's a pity." The owner of the store smiled, "A lively and lovely girl."

Song Yucheng pursed his lips, his black pupils gradually sank, stained with a blurred color, no longer the coldness of the past.

"We are just friends." Song Yucheng whispered, his voice was clear and cold, like a stream gurgling down from the mountains.

Diao Shuzhen finished choosing the supplies on his own, and chatted with the owner of the shop for a few words, smiling brightly.

Song Yucheng was carrying the wrapped bag, which was soft to the touch, as if there was something else in it.She froze for a moment, and found a bundle of red cotton rope inside.

She cast a puzzled look at the shopkeeper, and the shopkeeper blinked at her: "A little gift."

Song Yucheng put away the bundle of ropes and remained silent.Although the purpose of this thing is unknown, Song Yucheng nodded politely to express his gratitude.

Diao Shuzhen bought a pair of fox ears and put them on his head. He smiled brightly and walked around happily, looking very happy.When she laughed, the tails of her eyes were raised, and her eyes were not as sharp as usual, but instead had a sense of intoxication, which was quite seductive.

Song Yucheng looked at her back, his eyes darkened, and he really wanted to reach out and rub those ears.

It was not far from Hongxing Middle School. When he reached the gate, Diao Shuzhen took off his headdress and threw it back into the bag.The two showed their police officer IDs, explained their purpose, and walked in.
