I randomly have a new job every week

How did the murderer control the gas in the pipeline?

If this can be unraveled, the murderer's modus operandi will be clear.

Lin Yi came to the kitchen and saw the damaged gas pipe.

Then cautiously went up and touched it.

In the damaged place, there are still small barbs, which are obviously man-made.

Lin Yi looked at it carefully for a long time, but still couldn't figure it out.

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

How is it done?

"Ok?"

Just when Lin Yi was thinking about the problem, he found something was wrong.

Next to the hole, he saw a black substance smaller than a sesame seed, which didn't seem to be rust.

"Brother Li, do you have tweezers to help me find one?" Lin Yi said.

"Have you found anything?"

"There's a very strange thing on the pipe, I'm going to get it down and have a look."

"You wait."

Li Xianghui went to the forensic doctor, asked for a pair of tweezers, and handed it to Lin Yi.

Lin Yi took another facial tissue, and carefully removed the little black substance.

"What is this?" Gu Yiran raised his head and asked.

Lin Yi shook his head, stared at the little black substance and said:

"Not sure yet, I took it from around the hole."

"But it seems to be sticky. I just saw it stuck to the tweezers."

"viscosity?!"

Suddenly, Lin Yi ran to the window in a hurry, his eyes widened suddenly, because he saw what he wanted to see!

Although Du Juan is very beautiful, she is not virtuous, as can be seen from the furnishings in her home.

In other words, there are not many virtuous women who can be others' lovers.

So the window sills of their house are not clean, especially around the plastic-steel windows, which are covered with dust.

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

At the same time, Li Xianghui and Gu Yiran also walked over.

"What did you find?"

Lin Yi pointed to the white mark on the edge of the window.

"I understand the murderer's modus operandi."

Neither of them spoke, waiting for Lin Yi to continue.

"The murderer came to their house quietly before Du Juan came back, and then quietly made a small hole in it, and sealed it with tape at the fastest speed, so that the pipe would not leak in a short time."

"And then, how did he pull off the tape?"

"Fishing line!"

"The murderer is outside, using a fishing line to connect the tape at one end of the pipe. When the time is right, pull the outside fishing line, and the tape will be torn off smoothly, and the gas inside will naturally leak out."

"I understand!" Li Xianghui said:

"The white marks by the window should be traces drawn by fishing lines!"

"It's no wonder that other places are full of dust, only that one place is clean, it turns out that this method of killing was used." Li Xianghui said.

"The problem of the murder method has been solved, but there is another problem here. How did the murderer determine that Du Juan was asleep?" Gu Yiran said:

"When the incident happened, he was not indoors, so there was no way to determine Du Juan's state. If the tape was removed early, Du Juan, who was not asleep, would definitely notice it immediately, and his plan would be exposed."

"Camera!"

"Did you forget that during the search just now, a total of four pinhole cameras were found, corresponding to the two bedrooms, the toilet and the kitchen, and Du Juan was stared at closely, so her every move, in some people Her eyes are extremely clear, and it is not difficult to judge her state at that time."

Gu Yiran frowned, with a somewhat good-looking look.

"Is it possible that the person who installed the surveillance behind it was the one who killed Du Juan?"

"very possible!"

"Take these four cameras back first, and let the people in the technical department check to see if they can find the IP address hidden behind. If they can be found, it will not be difficult to find the murderer."

The two nodded in unison, and they thought so too.

"The situation at the scene is almost understood, let's go back first." Li Xianghui said:

"I'll call someone later to protect the scene. If there are other discoveries, come and check."

Lin Yi and Gu Yiran nodded, it was already late at night, it was not suitable to discuss the case, sleep on it and talk about it tomorrow.

"Song Zhe and Liu Fang should be more careful." Lin Yi said: "It will be bad if there is another accident."

"Don't worry, I have already called in advance." Li Xianghui looked at it and said:

"Go to work at ten o'clock tomorrow, don't have to go so early, sleep well at home."

"understood."

After briefly explaining a few words, everyone walked out together, and then got into their cars to go home.

In the second half of the night, Zhong Hai became quiet and low-key.

It's like a woman who has taken off her charming coat, becoming quiet and peaceful, but at the same time, a little lifeless.

Lin Yi leaned on his head with one hand and drove the car expressionlessly.

Dim street lights swept across his face one by one, his mind was full of the case.

There is no doubt that the murderer killed Du Juan at this time, indicating that she must know the truth of this matter, or know part of the truth.

The murderer was afraid that she would be exposed, so he acted ahead of time.

From this point of view, the suspicion of Song Zhe and Liu Fang will be greatly reduced, because they have been under the surveillance of the police, and it is completely impossible for them to commit murder.

As for buying murder to kill, it is even more impossible, because it is not possible to use such a crude method.

And no one dared to take such a job.

Money is a good thing, but life is more important.

After thinking for a while, Lin Yi didn't come up with a clue.

Now, the only clues left in his hands are those cameras.

I hope that people in the technical department can find out the ip address, so that the truth can be revealed.

Just like that, Lin Yi drove the car back home slowly, and then quietly went back to the room to rest.

But it felt like just a few minutes after falling asleep, I heard a knock on the door outside.

Lin Yi got up from the bed violently.

"He Yuanyuan, I hate your grandma!"

"How long has my grandma been dead?" He Yuanyuan stood at the door and said:

"I want to eat fried rice made by you, get up quickly."

"Be a few cents, I have to sleep, I don't have time to cook for you."

"If you are like this, I won't help you analyze the case."

"The analysis is over, you are useless as a tool man."

"But I found other clues."

"Wait!"

Lin Yi got up and opened the door, only to find that not only He Yuanyuan, but also Ji Qingyan was outside the door.

"What did you find?"

"You cook first, and I'll tell you when I'm done."

Ji Qingyan went downstairs with a smile, she was used to the two of them doing this.

With Lin Yi's current level, even if he didn't sleep all night, it wouldn't affect his mental state, so he simply put on his clothes and went to the kitchen.

And the three of Qin and Han were still sound asleep in the other villas and didn't get up.

Lin Yi is also very interesting, he has done a lot, and brought out their share.

"Tell me, I found another clue."

"Actually, it's not an important clue." He Yuanyuan said:

"Didn't I find out that Song Deyuan was working on a big project when I checked their company information yesterday? If you have enough time, you can check this partner company again to see if you can find some clues."

"That's it?"

"Yes, that's it."

"Fuck, what kind of clue is this, I wouldn't have gotten up if I had known."

"Aren't you too powerful?" He Yuanyuan said:

"Besides, I changed into new clothes today. You are the first to see it. You should be content."

As she said that, He Yuanyuan turned around, "I found out that I can wear many of the clothes my senior sister bought. The senior sister also said that I look like a star in this dress. What do you think?"

"You don't look like a celebrity, but rather an internet celebrity."

"Which internet celebrity?"

"Liang Zhichao is his mother."

"Damn!" He Yuanyuan scolded, "I thought, seeing how well you behaved, I'll tell you some more clues, haha...bye bye."

"Give you a raise."

"Come on, let's talk slowly."

He Yuanyuan smiled and said:

"After you left yesterday, I had nothing to do. I looked at their company's materials again and found an amazing coincidence."

"go on."

He Yuanyuan looked at Lin Yi mysteriously, her expression was somewhat similar to that of Qiao Xin.

"In the three months before falling off the cliff, almost every place Song Deyuan went to, before that, almost all cameras were changed, and the projects were all undertaken by their company!"

"Hmm? Are you sure?"

"Are you worried about my work? I've checked it twice, and it's indeed completely consistent."

This clue surprised Lin Yi, and it can be said to be a very important clue.

But the specific results that can be analyzed need to be discussed and discussed with everyone.

After eating, the three went to work separately.

He Yuanyuan left the car to Gao Zongyuan, rubbed against Lin Yi's car, and went to the company.

Woke up early, caught up with the late set.

After sending the two girls to work, when they returned to the branch office, it was already past ten o'clock, and Li Xianghui and others had already arrived.

"Come on, I'm missing you." Zhang Hui greeted.

"You're pretty good, kid. I heard that the method of killing people in a secret room was solved within minutes. There will definitely be developments in the future." Gao Mingjun said.

"It's all Brother Hui, Brother Zhang and Brother Gao took good care of them."
