Forensic Intern

Throughout the morning, there was no one in the captain's office. I heard that the captain had a meeting outside.

Tong Yu and Lu Wang were sitting in the forensic department's office, everything was as calm as usual.

At four o'clock in the afternoon, I received a call to the police. The caller was a villager, who excitedly told about the corpse he found on the river beach.

This time, the entire police station came alive again.

Tong Yu and Lu Wang took the reconnaissance box and followed Gu Yuan to the field. After driving for two hours on the road, they finally arrived at the river beach that the caller had mentioned.

The river beach is located between two villages, and there is a narrow road in the middle. To the east is Qingzhu Village, and to the west is Anming Village.

They put on protective clothing and followed Gu Yuan down the river beach. The river beach was very wide and very dry under the sun, with a cordon in the middle, and the trace inspection team had already started to investigate the scene.

Suspicious places were marked with number plates. Tong Yu took a quick look and found a black lady's leather shoe at number one, dragging blood at number two, and an unclear footprint at number three.

In addition to these things, there was a lot of rubbish at the scene, which made the investigation difficult.

It was Tong Yu's first official trip to the field, and he was inevitably a little excited.

When he walked in front of the corpse, his hands began to tremble with excitement.

The corpse was lying in the gravel by the river beach, with disheveled hair, facing down, unable to see the face clearly, with a knife stuck in the back, the knife was sunk deeply and tightly, and the black and clothes hid it. There were bright red bloodstains, but the sand under the body was completely red with blood.

The deceased wore only one shoe, and the other was left in a crevice of stones above the river beach. The white socks were stained with sand and a small amount of blood.

Gu Yuan observed the shape of the corpse as a whole: "The deceased showed signs of running away." He looked back at the black leather shoes stuck in the crevices of the stones, and then at the intermittent dragging blood on the river beach: "The deceased did not She chose to escape along the road, but chose to escape in a direction perpendicular to the road, indicating that the murderer may have transportation, and she had to run towards the complicated river embankment."

Gu Yuan carefully observed the sand under the body of the deceased and the sand under the nails: "There is a lot of sand in the hair, socks, clothes, and nails of the deceased, and there are obvious fresh traces of friction on the nails, which shows that the deceased is dead. There was a violent struggle before, and this is the scene of death."

"What do you think the occupation of the deceased is?" Gu Yuan asked suddenly.

Lu Wang replied: "The deceased was wearing a suit-style black suit. The material was average, and there were friction balls under the armpits and between the legs. This indicates that the deceased's economic status is average and he may be engaged in the service industry."

Speaking of this, Gu Yuan took off the mask, sniffed at the clothes of the deceased, and then put on the mask again: "There is a strong hot pot smell on the clothes, it may have been to a hot pot restaurant before death, or engaged in catering related occupations."

Immediately afterwards, Gu Yuan checked the pockets of the deceased's clothes, and took out an order card for a hotpot restaurant in the pocket of the deceased's coat, on which was written the five characters [Dongcheng Hotpot King], and the address and telephone number of the shop were also written on it.

The moment Tong Yu saw the brand name, Tong Yu tensed up, because the place where Wu Zhi treated guests to dinner yesterday was Dongcheng Hot Pot King!

Gu Yuan handed over the order card to Yan Ji: "The source of the corpse will be found soon!"

He checked the deceased's back again: "There were multiple stab wounds on the back, and the cause of death was preliminarily determined to be hemorrhagic shock."

Gu Yuan looked at the absent-minded Tong Yu: "Touch her fingers."

Tong Yu suddenly became nervous, staring at the muddy finger for a moment.

Gu Yuan: "Touch it, and then tell me how it feels."

Tong Yu overcame the fear in his heart, stretched out his hand and squeezed the dead man's fingers. The dead man's fingers were not as cold as imagined, and all the small joints could still move.

Gu Yuan: "How does it feel?"

Tong Yu's voice was a little excited: "There is still warmth, the distal knuckles have not yet formed rigor."

"Hmm." Gu Yuan squatted down and carefully checked the corpse spots and rigor on the body of the deceased: "The spots faded with light pressure with fingers, and the rigor mainly occurred in the jaw, shoulder and neck, and the death time was about 6 hours."

Yan Ji: "It's six o'clock in the afternoon, that is to say, the deceased was killed around 12 noon."

Since the deceased was facing upwards with a knife stuck in his back, it made further autopsy difficult. After it was determined to be a criminal case, the body was taken directly back to the dissection room of the police station.

The moment the body was turned over, Tong Yu unexpectedly saw a familiar face: "Zhang Xueying?!!"

"Why, do you know her?" Lu Wang asked from the side.

"I know!" Tong Yu was too surprised to speak: "This person is my mother's high school classmate!"

Everyone at the scene was quite shocked. Yan Ji said, "Do you have any contact information for the family members?"

Tong Yu thought for a moment: "I only know that she has a son."

Tong Yu didn't know much about Zhang Xueying's affairs. He only knew that Zhang Xueying divorced very early and lived alone with her son. He didn't know much about other things, and he didn't care about them before.

After returning to the police station, Gu Yuan conducted a further inspection on the body. After taking off the clothes of the deceased, he found twelve stab wounds on the back of the deceased. that knife.

"He didn't even take the murder weapon away, which shows that the murderer is very arrogant." Wang Yue rubbed his chin: "The possibility of a vendetta is relatively high. Find out if Zhang Xueying has any enemies."

The police retrieved Zhang Xueying's identity information and successfully contacted Zhang Xueying's son.

After Zhang Xueying's son's description, the police roughly knew why Zhang Xueying appeared on the river beach more than 200 kilometers away from her residence.

It turned out that Zhang Xueying's son, Zhang Min, took advantage of the weekend and secretly signed up for a tour group. He wanted to go out with his classmates to relax. , severely insulted his son, and slapped the child in front of many people.

Zhang Min ran away from the scenic spot in a fit of anger, so Zhang Xueying searched for the location of her mobile phone and came to the road beside the embankment.

After that, Zhang Min took a ride back home, but Zhang Xueying never came home.

It wasn't until the police came to the door that Zhang Min knew that his mother had been killed.

Zhang Min cried very sadly, trembling all over: "I didn't know this kind of thing would happen, I was very angry at that time, so I went back by myself..."

Tong Yu tried his best to comfort Zhang Min, he could understand Zhang Min's mood at the moment.

When Tong Yu's mother passed away, he was already an adult, but now Zhang Min is only 13 years old.

How should a 13-year-old face sudden changes?

"Do you want milk tea?" Tong Yu pointed to the takeaway bag on the table, there were five or six cups of unopened milk tea left in it.

Zhang Min shook his head: "Thank you, I can't drink it."

The police learned about Zhang Xueying's situation through Zhang Min.

Just as Gu Yuan guessed, Zhang Xueying did work at Dongcheng Hot Pot King, and she was on the night shift last night.

The hot pot restaurant basically operates 24 hours a day, so it operates two shifts. Zhang Xueying worked the evening shift last night, from ten o'clock in the evening to ten o'clock in the morning the next day.

In other words, Zhang Xueying ran to find her son as soon as she got off work.

"How did she get there?" Li Meng asked the waiter at the hotpot restaurant.

"bus."

"Is there anything unusual before you leave?"

"She said the child was disobedient, and she wanted to go back and break his legs!"

Li Meng nodded: "Is she very grumpy?"

"It's okay for the guests, but it's fierce for us."

Li Meng could tell that Zhang Xueying's interpersonal relationship was not very good. She spent most of the day at home and in hot pot restaurants. She didn't like communicating with people so much, and she didn't date other men after the divorce.

Colleagues speculated that Zhang Xueying somewhat hated men because of her unfortunate marriage.

It was such an ordinary woman, who would she provoke?

When it was almost 9 o'clock, Yan Ji of the trace inspection team shook his head: "No fingerprints were extracted."

"There are no fingerprints or the DNA of the second person left on the handle of the knife. Now the murderers are getting better and better!" Yan Ji sighed.

At this time, Zhang Xueying's body had been cut off her clothes, and she was lying on the dissecting table just like before her death.

Gu Yuan is carefully studying the angles of each stabbing edge: "Judging from the angle and direction of the stabbing of the knife into the back of the deceased, the murderer should hold the handle of the knife and stab into the back of the deceased obliquely from top to bottom."

"In other words, the murderer should be taller than the deceased. He is probably a man. Zhang Xueying's height is already 172cm. Women taller than her are rare!"

Until 9:[-] p.m., Zhang Min sat alone on the bench. He neither went to the autopsy room to see the corpse nor asked the police to find out the situation.

At 10 o'clock in the evening, Zhang Min's father rushed over, and he had already learned what had happened on the phone.

Seeing Zhang Zhiheng coming, Zhang Min immediately ran over and hugged Zhang Zhiheng, and then burst into tears.

"So he's going to cry!" Lu Wang looked at Zhang Min and said thoughtfully.

Tong Yu: "When people are extremely sad, they will not be able to cry."

"Man is a complicated creature." Lu Wang stood behind Tong Yu and said lightly.

Immediately afterwards, Zhang Zhiheng was invited to the interrogation room by Wang Yue.

Wang Yue had a general understanding of Zhang Xueying's situation through Zhang Zhiheng, but since the two divorced for a long time, Zhang Zhiheng didn't know much about Zhang Xueying's interpersonal relationship and current situation.

Since the scene of the crime was relatively remote and there were no surveillance cameras around, the field team tried to find witnesses between the two villages.

Everyone is very clear in their hearts that trying to find the murderer this time is undoubtedly looking for a needle in a haystack.

In order to find more clues, they began the autopsy work.

Zhang Xueying was lying on the dissecting table with pale skin all over her body.

Tong Yu was on the side to help Gu Yuan. He pried open the mouth of the deceased with a gag, and used a flashlight to explore the situation inside: "The oral mucosa is intact, without any damage or bleeding."

Lu Wang collected the oral mucosa of the deceased and removed the gag.

Gu Yuan handed the knife to Lu Wang: "Today you two will perform an autopsy, and Tong Yu will assist you."
