Hearing that He Jiahui had evidence, the panic in Lin Zhijian's eyes flashed.

And Huang Qiqi had an expectant expression, he felt that the truth of this case was about to be revealed!

Everyone's eyes were also on Ho Ka-fai to see what kind of evidence he would present.

He Jiahui looked at the forensic evidence and asked, "You should be able to find the packaging bag on the outside of the wet wipes in the garbage bag, right?" ”

"You can find it." Forensic nodded.

"The packaging bag that once put toxic wet wipes must also be able to test the cyanide composition, and that packaging bag is the evidence we are looking for!"

He Jiahui continued: "When the murderer changed the wet wipes, his hands would definitely touch the packaging bag of the toxic wet wipes, so on this packaging bag, in addition to the fingerprints of the deceased himself, the fingerprints of the murderer will also be left.

We only need to extract the fingerprints on the outer packaging of the toxic wet wipes, and then compare them with you, the person whose fingerprints match, and the person who changes the wet wipes, is naturally the murderer we are looking for! ”

After hearing these words, Lin Zhijian's face had turned pale, his legs were weak, and he sat directly on the ground.

This performance is tantamount to telling everyone that he is the murderer.

The source of the poison has been found, the murder method has also been deduced, and there are key fingerprints as evidence, and the whole set of evidence chain is very complete, which can be described as ironclad.

Although there is no fingerprint examination at this time, Lin Zhijian, as the real murderer, no longer intends to make senseless resistance.

"Cousin, are you really a murderer?" Cousin Lin Youqiang was the first to show an incredible expression.

"Senior Brother Yu was really killed by you?" Liu Wei looked at Lin Zhijian angrily and asked angrily: "You have been classmates since college, why did you kill him?" ”

Lin Zhijian smiled bitterly and replied in a low voice: "Because of the paper!" ”

Teaching assistant Xue Youlin suddenly remembered something, and he said: "I heard Professor Chen accidentally mention that some graduate students plagiarized their papers, but he just said it casually, and I didn't ask in detail.

Could it be that the person who plagiarized the paper is Yu Zhenghuang? Is it because he plagiarized your paper, so you killed him in a fit of rage? ”

"On the contrary, it wasn't him who plagiarized my paper, it was me who copied his." Lin Zhijian slowly raised his head, looked at the ceiling with dull eyes, and then said:

"I copied his papers, and he found out! I didn't expect him to set up the automatic recording function of the webcam, I turned on his computer and copied the process of his paper, and at the same time it was recorded by his computer.

In fact, he didn't know that I had plagiarized his paper at the time, until my paper was published not long ago, and he found that the content in it had a lot in common with his paper, and he checked the records on the computer to know that I had copied his paper. ”

"Is that the paper you published half a month ago?" Teaching assistant Xue Youlin showed a look of sudden realization.

Lin Zhijian nodded, and Huang Qiqi next to him used his brains again and asked, "He blackmailed you with the evidence of your stealing paper and demanded money from you, so you planned to kill him, right?" ”

"No, he didn't blackmail me." Lin Zhijian shook his head.

Huang Qiqi looked embarrassed again, and finally used his imagination once, but he guessed wrong.

Lin Zhijian continued: "Yu Zhenghuang took the evidence of my stealing thesis and went to our supervisor, Professor Chen, and he denounced me to the professor!"

But that paper was recommended to the journal by Professor Chen, and if it was revealed to be plagiarism, Professor Chen's reputation would also be affected. So Professor Chen decided to make a big deal a small thing and cover up the past.

Yu Zhenghuang didn't want the matter to end like this, so he planned to take the evidence and go to the Education Bureau to denounce me. When Professor Chen found out, he immediately approached me and asked me to find a way to solve this problem. ”

"So you killed him?" Liu Wei asked angrily, her expression at this time seemed to swallow Lin Zhijian alive.

"I didn't want to kill him, I have already apologized to him, as long as he doesn't go to the Education Bureau to sue me, then I will definitely not kill him! But he had to sue me, he said he wanted to get justice for himself! ”

Lin Zhijian said, showing a crazy expression, gritted his teeth and continued: "If I am found to plagiarize papers, I will be ruined and the rest of my life will be over!" So I have to kill him! ”

"Shameless! It's obviously your fault for plagiarizing papers, and if you don't admit your mistake, it's just that, but you kill people to cover up the truth, I'm bah! Liu Wei spat directly at the mouthful.

Lin Zhijian didn't dodge either, and let the spittle fall on him. He restrained his expression, then continued:

"In this world, the pursuit of justice comes at a price! Like life. So the other day, I came to this bar and took a pack of new wet wipes that I hadn't used, and when I went back, I used a syringe and injected hydride into it.

After that, I went to Yu Zhenghuang and told him that after my birthday, I would go to the Education Bureau to turn myself in, hoping that he would forgive me. And this idiot really believes that I will turn myself in! Also promised to attend my birthday party.

I deliberately invited Senior Sister Liu Wei again, because I knew that as long as Yu Zhenghuang came, Senior Sister Liu Wei would definitely come. I asked Senior Sister Liu Wei to buy some dim sum, and I guessed that she would definitely buy Feng Ji's cream crisp, because Yu Zhenghuang likes to eat it.

And if you eat cream crisp, you will use your hands, and the oil stains will get on your hands and mouth, and then Yu Zhenghuang will wipe his hands and mouth with wet wipes, and then when he eats something else, it will be his death!

Things were as I planned, I secretly changed the wet wipes in front of Yu Zhenghuang, watched Senior Sister Liu Wei hand the cream crisp to Yu Zhenghuang, and watched Yu Zhenghuang open the wet wipes to wipe his hands.

Then I deliberately talked to Yu Zhenghuang about some of the past, so that he didn't have the time to continue eating, I knew that the waiter here would often change the garbage bag, as long as the waiter took away the garbage bag, the poisonous wet wipes were also taken away.

After the waiter took away the garbage and replaced it with a new garbage bag, I said that the egg tart tasted good today, so everyone could taste it, in order to let Yu Zhenghuang die!

The next thing, you all know, we drank beer and ate egg tarts, Yu Zhenghuang took the egg tarts with his hands and drank beer, the egg tarts and beer were contaminated with cyanide, and he was poisoned! ”

After listening to Lin Zhijian's narration, He Jiahui sighed helplessly. He could feel that until now, Lin Zhijian still did not have half a point of remorse in his heart.

It was Lin Zhijian's fault for plagiarizing papers, even if he was reported and punished, he deserved it.

But instead of realizing his way back, he went further and further down the wrong path, and in the end he was not only ruined, but also spent the rest of his life in prison.
