Immediately, Lin Yi came to her bedroom.

The bed is very messy, there are also scratches, cosmetics on the dressing table, scattered, but it is not like fighting traces, more like struggle.

After reading a circle, I didn't have any suspicious things in the family, then returned to the living room, and Li Xiang Hui and Gu Yitang.

"What are the special discovery on the scene?"

"I found these four things?"

"Pinhole camera?"

Li Xianghui nodded, "Tibetan is very hidden, all over two bedrooms, bathrooms and kitchens, 360 degrees, no surveillance of the dead end."

"Du Fu should not know this?"

"Guess is like this, but what is going on, it still needs to be analyzed, and now you can't conclusion."

"The body is lifted, is there a preliminary result? Can you determine whether you commit suicide?"

"In addition to these four cameras, I haven't found useful clues, but I am not too suicide." Li Xianghui used chin and refers to the position of the kitchen.

"You come with me."

The two came to the kitchen, and Lin Yi looked at the position of a stove.

The switch is a closed state.

According to the interference, if it is suicide, the gas switch should be open, and it is not right.

"That is not a focus, you see this."

Li Xianghui pointed to the gas pipeline:

"There is a corroded hole, but after testing, some people find traces that have been destroyed, basically able to determine whether he kills, but there is no clue, and it is difficult to trace it."

Lin Yi made a deep breath.

Song Deyuan's question has not been resolved, and now there is a chamber murder case.

This case is more and more interesting!

Just when two people speaking, a forensic doctor came over.

"Li team, the result is already coming, the deceased Du Fu is because of the sleeping process, the excessive carbon monoxide is smoked, leading to poisoning, there is no scar, and there is no trace that is infringed, it can be determined that there is no people before. The battle is a typical murder case. "

"I want to ask, when people are sleeping, the excessive carbon monoxide is smoking, is it won't be awake?"

"This may be present, but it is necessary to depend on the situation, and the leaked carbon monoxide content is not big. When she reacted, the physical function has affected, and it is very difficult to do effectively."

"And her bed is very messy, there is a wrinkle in many places in the bed, and it should be struggling for a period of time, but I didn't play any effect."

"Okay, I understand, thank you."

According to the situation of the dead, the forensic turned and left, Lin Yi three gathered a piece and started analyzing the case.

"Is there a monitoring near this? Is there a suspicious person?"

Gu Yisheng shrugged, "Here is the old community, the monitoring is displayed, there is no such thing."

"It is a bit strange." Lin Yi said:

"After the police, our people have been secretly followed by him, when is the murderer going in to destroy the gas pipeline?"

"I have already asked people who are responsible for watching Du Fu, they can decide, after Du Fu, did not come, and no one has entered her home."

Lin Yi's doubt is also the question of others, and I don't want to understand what is going on.

Now the problem has fallen into a deadlock, how did the murdere come in to kill?

"Is there such a possibility, the murderer coms in in advance, and achieve the purpose of him killing?"

"There is only one possibility, and their family lives in the sixth floor, it is not too likely to come in from the windows outside, so it is easy to discover." Lin Yi said:

"But the problem is that the gas leakage is the pipeline. There is no switch in that place. Once the leak is sustainable, after the Rhododendron is coming back, it will definitely find it wrong, it is more impossible to sleep, this is contradictory."

Lin Yi's question is also the key point of this murder case.

How does the murderer control the gas in the pipe?

If you can solve this, you can clear the murderer's committee.

Lin Yi came to the kitchen and saw the destroyed gas pipeline.

Then I carefully touch it.

Where is destroyed, there is a small stripping, which is obviously human.

Lin Yi is still looking for a long time, I always don't understand.

There is no one in it, but the other party can control the opening of the hole.

How did you do it?

"Ok?"

Just when Lin Yi thought the problem, it was discovered.

He saw the side of the hole, there is a black material that is smaller than sesame seeds, it seems to be rust.

"Li Ge, there is no tweezers to help me find one." Lin Yi said.

"What did you find?"

"There is a very strange thing on the pipeline, I am going to get it down."

"You will wait."

Li Xianghui walked to the forensic doctor, to come to a small tweezer, then hand it over to Lin Yi.

Lin Yi took a napkin, and then carefully, took the small black matter.

"What is this?" Gu also explored his head asked.

Lin Yi shook his head, staring at the little black matter:

"I can't be sure it is temporarily, I take it around the hole."

"But it seems to have some sticky, I just saw it sticking to the scorpion."

"viscosity?!"

Lin Yi suddenly, hurriedly ran to the window, suddenly the eyes were rushed, because he saw something you want to see!

Although Du Fu is very beautiful, it is not a goodbye, which can be seen from the furnishings in her home.

Or, you can give others a woman who loves people.

So the windowsills in their home are not clean, especially around the plastic steel window, covered with dust.

But there is a white line that divides the dust on the plastic steel window into two trips.

At the same time, Li Xianghui and Gu have also gone.

"What did you find?"

Lin Yi refers to the white mark on the side of the window.

"I understand the murderer 's journalism."

No one didn't speak, waiting for Lin Yi to continue.

"The murderer came to their home before, and then quietly came out of a small hole, with the fastest speed, with the tape, so that the pipeline will not leak in a short time."

"Then, how did he pull the tape?"

"Fish line!"

"The murderer is outside, with a fish line, connecting the tape ends of the pipeline, after the time is mature, pull the outer fish line, can smoothly pull the tape, and the gas inside will also be unhappy."

"I understand!" Li Xiangzhi said:

"White imprint of the window should be the trace of fish line!"
