Just as Lin Bayi just said, the materials that can be used to prove the facts of the case are all evidence.

On this basis, evidence can be roughly divided into the following two types, the first is physical evidence in the form of objects or words, which is called physical evidence.

The second type is a statement made by a person who knows the true circumstances of the case to the judicial organs or relevant personnel about the circumstances of the case that he or she knows, which is called a witness.

And the thing that the police officer at the door was about to bring in was the physical evidence that could directly prove Lin Bayi's guilt, and he believed that this evidence was something he could not deny no matter what.

Liu Hao stepped forward and slowly opened the door, and after a while, the two police officers walked into the room with a corrugated cardboard box.

The corrugated box in front of me was the one I found from Song Yuan's house, and what was in that corrugated box was all forty-six issues of White Night Magazines, including the three issues of the murder magazine.

As we have previously inferred, the murder can only be committed by the real murderer, after all, it has to be highly overlapping with the circumstances of the crime scene, and it is impossible to write such a book if it has nothing to do with the case.

After listening to my general explanation, one of the leaders said thoughtfully: "In other words, this corrugated box can only be mailed to Song Yuan by the person behind the scenes?" ”

"That's right! I guess the purpose is to blame Song Yuan for the whole case through the murder in the corrugated cardboard, and let Song Yuan take the blame for himself! ”

However, what Lin Bayi didn't expect was that in the rush to the hospital, Lu Yuan directly injured Song Yuan, so that Song Yuan had already been admitted to the hospital before he could open the corrugated box.

As a result, it also indirectly led to the bankruptcy of Lin Bayi's plan.

"Senior Lin Bayi, I sincerely ask you once, have you ever seen or come into contact with the above three issues of murder magazines?"

He glanced at me and said without thinking, "No! I've never seen it, and I don't know what you're talking about. ”

"Really?"

"It's true! Could it be that you can still find my fingerprints or DNA information in those magazines? Lin Bayi said this sentence almost without thinking.

It could be seen that he was very careful when preparing the magazine, and he must have put on something like rubber gloves, so he dared to say it in front of everyone present.

"As you said, we didn't find anyone's fingerprints or DNA information in those magazines, so the killer did a pretty good job."

As soon as the words fell, the scene was in an uproar, some people were frightened, some people were puzzled, but most people still cast suspicious glances.

"Since fingerprints and other DNA information were not found in the magazine, how can they be used as evidence?"

Liu Hao and I looked at each other and smiled, and did not rush to respond immediately, and only after everyone present calmed down again did I continue to speak in front of them.

"It's true that the killer didn't leave his fingerprints and DNA information in the magazine, however, the police have made a major breakthrough in another place!" I walked over to Liu Hao and took a trace detection report from him.

"The members of the Traces Section of the Z City Police Department spent a lot of time checking all the magazines here, but they didn't find any clues in the magazines. However, they did not give up because this case involved the lives of too many people, and everyone did not want to let the real murderer go unpunished!

I looked straight at Lin Bayi, took the trace report in my hand, and slowly walked in front of him: "After days of hard work, the members of the trace department finally found three incomplete fingerprints and a hair sample suspected to be lost by the suspect inside the corrugated cardboard box. After cross-comparison, we found that both those fingerprints and the DNA information of the hair samples matched you exactly!

If you've never seen this corrugated cardboard box, or seen these magazines that record killings, can you explain why you can find your fingerprints and hair in the cardboard box?

The only explanation is that this cardboard box is what you are going to use to divert the attention of the police, and you want to blame Song Yuan for the whole case with the contents of the cardboard box.

Now, Lin Bayi, what else do you have to say! ”

When I threw the appraisal report in front of Lin Bayi, I could clearly feel that his whole body was trembling, and to this day, I feel that Lin Bayi is indeed an old man who is over the age of old, and not as aggressive as he saw at the beginning.

When I presented this overwhelming evidence, all the attention of everyone present turned to Lin Bayi.

The leaders of the police station, who had been on his side from the beginning, were now eager to immediately separate themselves from him. In the eyes of those leaders, this former pride of the police community has long been reduced to an out-and-out murderer.

The fat old man gritted his teeth with hatred for him, if it weren't for the fact that there were so many policemen present, I was really worried that he would immediately pounce on him and fight with Lin Bayi.

As for Lin Feng and Xiaoxue, the eyes they looked at Lin Bayi were full of doubts. These two stupid children still don't understand why their father committed such an unforgivable thing.

"No way, no way to leave my fingerprints, I noticed that! Could it be。。。。。 ”

"So far, haven't you explained everything clearly? Do you want to keep hiding something? I walked quickly up to him, snatched the test report, and continued to speak in front of everyone present.

"Five years ago, there was a girl named Yin Jiahui in Heijin City. In order to save her, his brother Yin Da was beaten by the underworld and became disabled for life, but his parents accepted monetary compensation from the underworld because of greed for money, so that his brother could not get a righteous result.

And Yin Jiahui, I happened to meet you at this time, Lin Bayi!

You promised to give Yin Jiahui a large sum of money in exchange for her life for you. And this incident has become an introduction, the cyanide murder case on the train is the result of the joint efforts of you and Yin Jiahui, you are responsible for providing the method of killing, and Yin Jiahui is responsible for carrying it out!

After successfully killing Ye Wushuang, Yin Jiahui is willing to sacrifice herself to erase the evidence for you. And it was at this time that in order to divert the attention of the police, you thought of the method of planting the blame. So you cut off Yin Jiahui's hands and mailed them to Song Yuan along with those magazines that were printed with murder.

But what you didn't expect was that because of the things in the hospital, Song Yuan, who was seriously injured, did not open the package, leaving fingerprints and DNA information. On the contrary, your fingerprints and DNA information are left on the corrugated cardboard, which is the most effective proof to identify your crime! ”

At this point, I suddenly felt a strange feeling, I didn't react at the time, and it wasn't until a few days later that I realized what that strange feeling was, however, by then, it was already too late.

I was so confident that I made the same mistake as I did when I first saw the CCTV footage of the office building.

Lin Bayi glanced at me, and he calmed down from the shock before. He leaned on his crutches and slowly stood up from his position: "You analyzed it well, in that case, why don't you also tell me the motive and method of killing Song Shuai?" ”

What a rampant guy! When Lin Bayi opened his mouth to say this, Liu Hao couldn't stand it anymore, and while contacting more policemen to maintain order at the scene, he asked Niu Pengyu and another young police officer to step forward to control Lin Bayi and prevent him from making some radical moves.

After Lin Bayi knew that his crime was exposed, it was hard to guarantee that this old guy would not jump over the wall in a hurry and do some crazy things. After all, he is the mastermind behind the killing of so many people, and no one knows what kind of heart this guy has under his sanctimonious appearance.
