Lin Lei glanced at Liu Ziyun, turned to Officer Li and said, "Her testimony is credible for two main reasons. First, as long as anyone is not a fool, out of instinct, he has the mind to seek advantages and avoid disadvantages. If Liu Ziyun lied and said that she saw a 'headless ghost', and it turns out that she was lying, then she must have something to do with the murder, and even she is very likely to be one of the murderers, at least an accomplice of the murderer. If he is not completely sure, from the murderer's point of view, he will never easily give such a crucial testimony and put himself in extreme danger. ”

After a pause, Lin Lei continued: "Second, the deceased was an adult man, and his head was cut off. Generally speaking, it is not easy for women to complete such a criminal process. In addition, Liu Ziyun and the deceased Du Chengming did not know each other, and Liu Ziyun did not come to Tianchang Town five years ago, so it is very unlikely that the two will be related. ”

Officer Li seemed to understand what Lin Lei meant, nodded and said, "Detective Lin, do you mean that Liu Ziyun has no motive for committing the crime?"

Lin Lei bowed slightly: "Yes." It is not very likely that a person who has no motive for committing the crime will become a murderer, so I choose to believe Liu Ziyun's testimony. ”

Lin Lei glanced around the crowd, and finally stopped his gaze on one person.

That person couldn't help but lower his head, not daring to look at Lin Lei.

Lin Lei stared at this person and said coldly: "After the incident, the police inspected the back door of the hotel and found an interesting phenomenon, that is, only the fingerprints of the proprietress Widow Chen appeared on the latch of the back door. According to Boss Chen, from the night she checked the back door to the next morning, she did not open the door once...... Now let's go back to Liu Ziyun's testimony, she once saw the figure open the latch of the back door and walked out, which means that the latch of that door will definitely leave the fingerprints of the figure. Here again, the following situations will occur. The first is when the figure returns and closes the back door, and the second is when an accomplice closes the back door for the figure. ”

"Think about it, in either the case is that the fingerprints on the door are wiped clean and nothing is left, or the gloves are worn to commit the crime, or the fingerprints of the suspect will be left on the door. After a detailed inspection by the police, they found that there were no traces of wiping on the latch and no traces of glove contact, so the problem seems to be very simple-"

Lin Lei looked at the pale Widow Chen, and said lightly: "Only you can do this case!"

Everyone was taken aback and looked at Widow Chen in disbelief, and Widow Chen trembled violently and almost fell.

At this time, Officer Li gave an order, and two policemen immediately rushed to Widow Chen and restrained her.

Widow Chen did not resist, nor did she make any radical movements or words, but just closed her eyes and did not say a word.

Officer Li asked Lin Lei in a low voice: "Detective Lin, is the murderer Widow Chen? If that's the case, she looks a little too stupid! There are only her fingerprints on the back door latch, doesn't this tell the police unmistakably that she is the murderer? How can there be such a stupid murderer?"

Lin Lei frowned slightly, sighed softly, and said unhurriedly: "Many murderers pursue the so-called 'perfect crime', but the real 'perfect crime' only exists in film and television works, and it is almost impossible to happen in reality. The reason is very simple, there are not as many things you can control as you think, and any unexpected situation will make your so-called 'perfect crime' become bullshit. Liu Ziyun saw the 'Headless Ghost Black Shadow', it was an unexpected situation!"

As Lin Lei said, the murderer designed the crime process, even if it reached the point of exhausting the last resort, who could calculate that in the middle of the night, when he happened to go out, Liu Ziyun would get up and go to the toilet?

It happened that she didn't say anything about going to the toilet, but she happened to find that the curtains were not closed, and when she came to close the curtains, she saw the figure of a headless ghost!

This kind of thing, as a murderer, when planning the crime process, how can it be calculated?

After a pause, Lin Lei then explained: "In the entire inn, there is only one person, who was in Tianchang Town five years ago - she is a resident of Tianchang Town, of course she is here!"

"That's right, Widow Chen, the innkeeper five years ago, must have been in Tianchang Town!" Officer Li thought about it, and felt a little unstable, "Detective Lin, maybe she left Tianchang Town at that time?"

Lin Lei waved his hand and replied, "This is not important. Even if she is in Tianchang Town, she can easily make an illusion of 'going out', which is untraceable. The point is that among these people in the hotel, only she is most likely to be in Tianchang Town at the time of the crime five years ago, and this is enough, this is not conclusive evidence. ”

Lin Lei is right, so far, he has not presented any evidence, just pure reasoning.

Even if there are only the fingerprints of Widow Chen in the back door, it is based on Liu Ziyun's testimony, which does not explain anything - it is a universal truth that it is heavy on evidence and light on confession.

Lin Lei glanced at Widow Chen again, she was still silent, but her whole person was a little prostrate, her face was pale, and her spirit was very poor.

Lin Lei sighed softly, no longer looked at him, but said to Officer Li: "If you want to solve this case, the starting point is still the 'headless ghost' case five years ago, when the murderer revealed a big flaw, and this flaw can even directly lock the real murderer." ”

"Ah?——" Officer Li exclaimed, looking at Lin Lei incredulously, "Detective Lin, what is the flaw?"

Lin Lei said word by word: "The headless ghost who swaggered through the market. ”

"Headless ghost swaggering through the city, this ......" Officer Li didn't react for a while.

Lin Lei's eyes narrowed into a slit, and he slowly explained: "Although the so-called 'headless ghost' was walking on the street in the early hours of the morning, it was also on the street! The facts eventually proved that even in the early morning, there were at least three people on the street who saw his trace! These three people were all adult males, and if one of them came forward to check what was going on, wouldn't the murderer be exposed on the spot?"

After a pause, Lin Lei continued: "If a person doesn't dare to come forward, then there must be groups of diners who drink and eat barbecue at night, and if the headless ghost encounters a group of such people who come forward to check, the murderer will be deflated on the spot." ”

Officer Li nodded, agreeing with Lin Lei's statement: "That's true, this murderer is too bold! No, it's not bold, it's stupid! Pretending to be a headless ghost to swagger through the market, if it's just to scare and scare a certain person, it's really too dangerous to walk on the street with a swagger! Once he encounters a group of passers-by, he can't run away at all!"

Lin Lei suddenly turned his head to look at a person-

The man was still holding a bottle opener, sitting in the corner, fiddling intently, as if the tension in the outside world had nothing to do with him!

He smiled innocently, his eyes came out of the "toy" in his hand, and he couldn't see anything else.

Officer Li seemed to understand something, his eyes widened, his mouth opened wide, and blurted out: "Detective Lin, the murderer is him?!"

Lin Lei let out a long sigh, with a hint of unbearability in his eyes,......
