I'm a New Police Detective: Specializing in Solving Strange Cases

He discovered at the beginning that all the footprints and shoe prints stopped at the location where Xiaojing was and did not go forward, but there was only one footprint that was still going towards the window.

But this footprint was very strange, as if it was left by women's shoes. He compared the sizes again, and yes, size 36 was the mark left by the soles of women's shoes.

The strange thing is that the shoe prints are darker at the forefoot and lighter at the heel, and some even show no trace of the heel.

Wang Qian also noticed something strange. He had learned a lot from Lin Yu during this period and could even analyze simple footprints.

Lin Yu wanted to test them: "Did you find anything different?"

Yu Xiaoyu squatted beside Xiaojing's body: "Chen Jing's body is just as you said, there is only one groove of hanging, no other signs of injury, and her eyes and expression do not look painful, it does not look like she committed suicide or was hanged."

Zhang Xiaonan analyzed the furnishings in the room: "The items in the room, including the bed, are all neatly arranged. There is no sign that anything on the cabinets and tables has been moved."

Lin Yu looked at Wang Qian: "Wang Qian, what do you think of this row of footprints?"

Wang Qian measured with his hands, then walked in the direction: "This row of footprints is heading towards the window, and it matches the half footprint outside the window. I think this is the direction the suspect ran away."

"Then did you find anything different about this footprint?"

"If there is any difference, it is that the forefoot is deep and the heel is shallow. This person is obviously walking on tiptoes."

Lin Yu said "Hmm": "You are right, but only half right."

Then he asked the three of them to come over: "Look, I have carefully compared this shoe print, and it is the same size as Chen Jing's shoe, but Chen Jing can't possibly reach outside the window?

So I have a bold guess that the suspect escaped wearing Chen Jing's shoes, which would explain why the soles of the feet are deep and the heels are shallow.

Because his feet are big and the shoes are too small, when he wears them, he can only fit half of his foot in, like this."

Then he also took out a pair of Chen Jing's shoes and walked around to demonstrate.

The three of them suddenly realized: "Oh, no wonder, so he gave Chen Jing new shoes, and these new shoes are spotless, and he wore the old shoes away."

Wang Qian took a pen and wrote down the information and knowledge points in his notebook: "I understand. It is impossible for a person to keep the house spotless if he wears shoes. This murderer seems to be very smart, right?"

Lin Yu frowned and replied: "Yes, that's right, we may run into someone with strong reconnaissance ability again."

Then he followed the footprints to the window and jumped. There was a balcony-like eaves outside the window, which was very narrow and just big enough for one person to stand.

The king had just conducted an investigation here. Lin Yu jumped down and landed on the ground. The ground was covered with grass, so it was very easy.

He was measuring the height. The second floor was just like an ordinary building, not very high, but it was still a bit difficult to climb up, but jumping down was not a problem.

He was wondering where this person had climbed up. He looked around and saw that there was nothing to climb on the wall. It was impossible for an ordinary person to climb up, otherwise there would be too many thieves.

If a ladder was used, there would definitely be two footprints on the grass, traces that even rain could not wash away.

But there were no such traces on the grass here. He tried to climb up without using any magical powers, but failed after several attempts.

The height between the windowsill and the eaves is at least 3 meters. No matter how strong a person's jumping ability is, it is impossible to jump so high, unless he has the rope hook used by ancient martial artists.

Soon, Lin Yu shook his head and denied it. How could an ordinary person use this?

He jumped onto the eaves again, but there were no footprints on the eaves. It might be because of the rain.

He jumped onto the roof of the second floor again and tried to find some clues on the roof. Apart from leaves, there was only a small amount of soil left on the wall by rain.

A gust of wind blew, and some leaves were blown to the ground.

In the direction where the leaves were blowing, he saw a rusty object on the railing. It looked like an iron hook, but it was a hook with two ends. He had never seen it before. What was it?

This doesn't look like something on the railing. It was most likely brought here from somewhere else, but what is it for?

He picked it up and jumped onto the window sill below, and asked Wang Qian and the others, "Have you seen this thing? Do you recognize it?"

Wang Qian took it and looked at it again and again, then shook his head and handed it to Zhang Xiaonan and Yu Xiaoyu, both saying that they didn't know what it was.

Never mind for now, take it back and ask Du Ming.

It turned out that there were things that Lin Yu didn't recognize. Several people laughed softly with their hands covering their mouths as if they had discovered a new world.

After returning to the local police station, they verbally reported the footprint analysis to Du Ming.

At this time, the shoe prints they extracted in the morning had already been analyzed in the detachment, and the results were the same as Lin Yu's analysis.

Only one shoe print of size 36 was in a suspicious direction, and the rest were left by family members who entered in the morning, while the girl was hanged to death in the evening, so the possibility of family members committing the crime can be ruled out first.

Then the person who has the best relationship with the girl is her boyfriend, but he is in the hospital now.

So they came up with two plans and sent two people to keep an eye on Chen Jing's boyfriend and prevent him from running away.

On the other hand, we need to find out what this iron object is and what its function is.

Then he said, "Shall we go ask Captain Du?"

Wang Qian said, "Why don't we go ask the local villagers? It seems a bit embarrassing to ask Captain Du. If we don't know such a thing, it will be embarrassing if it gets out."

Lin Yu laughed: "What's so shameful about this? We should not be ashamed to ask questions, so that we can make progress."

When I asked Du Ming, he laughed at me, “Haha, this is called a leech nail, it’s normal that you young people don’t know it.

This thing was very common in the past, and was generally used in old-style houses to fix wooden beams on top of wooden beams. "

Lin Yu asked: "This was found on the roof of the scene. Does this thing have no other use?"

"Other useless ones."

Lin Yu said okay, then checked the computer himself and found that there was indeed no other use for it.

However, this leech nail looks quite heavy and thick. If it was really left by the murderer, then it must have some other purpose.

So we have to do the test first. It’s too far from here to the detachment and the time is too tight. We won’t have time.

He took out the All-Things Universe Instrument and scanned it for a while. He was overjoyed and surprised. The scan results showed that there were hemp rope fibers, cement components, and a kind of cloth fibers.

This instrument will analyze each fiber: the last type of cloth fiber belongs to the polyester white gloves.

He printed out the analysis report for use as evidence comparison.
