National Forensic Doctor

Boom.

A long ladder was against the wall. Mu Zhiyang climbed up first and tried it, then came down and gave it to Jiang Yuan. At the same time, he tied a safety rope to Jiang Yuan.

Jiang Yuan climbed up without hesitation, carrying a horseshoe mirror with him.

There are mainly several types of marks on the wall. One is naturally formed, caused by moss, peeling wall skin, paint discoloration, erosion after rain, etc. The second is the traces of clothing touching and rubbing. In addition, there are traces of suspected footprints.

Jiang Yuan wants to put aside the first two and focus on the other two.

He looked very seriously, and his body tilted at a 90-degree angle with the ladder.

Shen Yaowei asked someone to hang another safety rope from mid-air to help Jiang Yuan stabilize his body.

On the opposite side of Jiang Yuan, another criminal police officer was holding a camera and constantly filming. At the same time, there were people holding cameras below, recording the appearance of several people collecting evidence.

There were almost 10 people busy on just this wall.

Some villagers saw their movements from a distance and came over without saying a word.

Life in the village was monotonous. If someone's sheep was lost, it would be a big event that shocked the whole village, no less than if someone's shepherd was lost.

So many policemen were enough to attract the whole village to watch.

Wang Chuanxing and others had set up isolation belts in advance, but the ground outside the isolation belts had been trampled into pieces.

Some people bravely entered the isolation belts. Although they were quickly pressed down, the atmosphere at the scene still became tense.

If this were ordinary on-site investigators, they would probably be annoyed to death. Jiang Yuan didn't even turn his head back. He brought so many people out, not just to eat dry food.

Jiang Yuan concentrated on studying the footprints himself.

It was not easy to judge the type of species from the traces left by the clothes. I guessed that it should be related to the jeans that were bunched up in the closet. Later, it might be possible to compare them through the stains rubbed off.

In comparison, footprints were easier to judge on the spot.

Jiang Yuan's research focuses on two things: first, whose footprints belong to them, and second, whether they were climbed up or down.

Soon, Jiang Yuan made a judgment-

There were both footprints at the scene from climbing up and from climbing down.

In other words, not only did someone climb into the victim's room on the east side of the second floor through the rope tied with jeans, but also more than once.

For general trace inspection, the investigation is basically over at this point.

Jiang Yuan asked people to copy the footprints separately, and then carefully distinguished them. Soon, it was found that these footprints basically belonged to two people, one male and one female.

The male should also be underage, and the female's footprints matched the victim Sun Xiuwen's own footprints.

Not only that, judging by the center of gravity of the footprints, these footprints still have ups and downs.

In the fairy tale "Rapunzel", Rapunzel let down her long hair to let the prince climb up the tower, and then secretly dated.

And through the traces on the wall of the Sun family, Jiang Yuan saw that it was probably traces of trysts again and again.

In other words, although Sun Xiuwen was still young and a virgin, she was most likely secretly dating a boyfriend in this way.

For a murder case, this clue must be investigated.

However, considering the reputation of the deceased, Jiang Yuan climbed down the ladder and did not make a big fuss to arrange the work. Instead, he asked the village committee to persuade the villagers to leave, and then asked Meng Chengbiao to re-interrogate the victim's mother in the living room of the Sun family.

…

"Does Sun Xiuwen have a boyfriend?" Meng Chengbiao noticed that the victim's mother was not very emotional, and time was tight, so he didn't lay the groundwork and played a straight ball.

The victim's mother was stunned and then shocked: "How could she have a boyfriend? Wenwen is only 15 years old."

"Do you know or not?"

There was no one else in front of him, and Meng Chengbiao asked coldly and bluntly.

The victim's mother was stunned for a moment, and then whispered: "She may have a little boy she likes, but she probably doesn't have a boyfriend."

"What's the name of the little boy she likes?" Meng Chengbiao asked.

"I don't know if it is true or not. I also saw it when I secretly looked through her desk." The victim's mother said hesitantly.

Meng Chengbiao said in a serious tone: "Name!"

"Li Haojie. He is a classmate from the next class." The victim's mother's voice was low.

Meng Chengbiao asked the victim's mother to write down the name, and then sent it to the WeChat group and Jiang Yuan's private chat, and then said: "When you look through something and see this name, go and have a look."

He was looking for evidence. It was impossible for the victim's mother to say what it was. Apart from anything else, her husband was still on the suspect list. Her own suspicion level would be two levels lower, but it could not be said that there was no suspicion at all.

Although it is common that there is a stepmother and a stepfather, there will be a stepmother from time to time.

It is not too difficult to understand that children in reconstituted families face more risks, even life-threatening dangers.

There were no traces of the first scene in the Sun family's house. It can only be said that the stepfather's suspicion has weakened, but his suspicion cannot be ruled out.

The victim's mother had no choice but to take Meng Chengbiao and another police officer upstairs to look through her daughter's notebook under the camera.

Soon, in a notebook with a butterfly drawn on it, the victim's mother turned to several pages with Li Haojie's name written on them.

Meng Chengbiao nodded, asked someone to take a few photos, and sent them to Jiang Yuan.

At the same time, Wang Chuanxing also found Li Haojie.

"A week ago, Li Haojie's family moved to the city and rented a house. Li Haojie also transferred to No. 32 Middle School in the city." Wang Chuanxing reported to Jiang Yuan.

"What was the reason for moving?" Jiang Yuan asked.

"It was said that he went to Changyang City to work and earn more."

"What do his parents do?"

"His father is a carpenter, and his mother found a cleaning job." Wang Chuanxing described it as objectively as possible, so he did not directly point out that Li Haojie was the murderer.

"Does his family have a house in Changyang City?"

"Rent a house."

"Is it cost-effective to rent a house and work?"

"It's definitely not cost-effective." Wang Chuanxing didn't even need to look up information, and said familiarly: "The house they rent in Changyang City costs at least 1,200 yuan a month. His mother works as a cleaner, and only earns more than 1,000 yuan a month. It's better to farm at home. Not only can he take care of the elderly and children, but he can also grow some vegetables and raise some chickens and ducks."

Jiang Yuan nodded and said, "Bring Li Haojie's family here."

"Yes." Wang Chuanxing excitedly gave the order.

The case has a clue, and the criminal police involved in the case investigation are very fulfilled. This is a higher enjoyment than making money.

"Where does Li Haojie live? Go to his house to investigate." Jiang Yuan didn't waste time.

For murder cases, it is best to find the first scene.

Li Haojie's house is located on a small hill in the middle of the village.

His house is a three-story building built 10 years ago. It looks half-new and half-old, and the yard is relatively large.

Jiang Yuan first walked around the house, then inspected each room one by one.

For a long time.

Wang Chuanxing reported: "Li Haojie, his parents, and his brother have all been brought back."

Jiang Yuan breathed a sigh of relief. He had also walked around Li Haojie's house twice, but he didn't feel like he was at the scene and didn't have any evidence.
