There are three suspects left, Wu Liyang, a truck driver in room 706 next to the deceased, and Du Jun, a convenience store owner in room 710, and Li Chengzhi, a waiter that night. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Lin Lei took a deep puff of his cigarette and said to Lu Yun with a smile: "Now there are only three people left, who do you think can be excluded again?"

Lu Yun has also read the case materials in detail, and she has also seen the video taken by Qiao Yan, she has some thoughts in her heart, but she is not sure.

Lu Yun pondered for a moment, and said tentatively: "Li Changxing was killed in his sleep, so the murderer must have a way to enter the scene without waking him up." I think that if the murderer enters and exits through the window, cleans up the shoe prints left on the air conditioner afterwards, and finally puts a layer of dust on it, it will completely hide people's eyes. ”

Lu Yun's statement pointed the finger at the two people next to the deceased.

Wu Liyang in room 706 and Du Jun in room 710 both had soybean-sized sweat droplets on their faces, you look at me, I look at you. The meaning couldn't be more obvious, if you are not a murderer, then the other party must be.

Officer Li frowned: "Advisor Lin, what Officer Lu said—"

Lin Lei smiled, he glanced at Lu Yun, and said, "Lu Yun, you are right, the key point of this case is how to enter the scene without waking up the victim Li Changxing. ”

Officer Li looked at the truck driver Wu Liyang, and then turned his head to look at Du Jun, the owner of the convenience store, with a puzzled look on his face.

After all, Officer Li is also an old criminal policeman, and even if his logical reasoning ability is not as good as Lin Lei's, his IQ must be online.

Officer Li asked Lin Lei with some puzzlement: "Consultant Lin, if you enter and exit through the window, it seems that ...... It seems a little unreasonable!"

Lin Lei smiled slightly, and said lightly: "Of course I can't say it-"

It's coming, it's coming!

The next reasoning must be the essence part, and everyone looked at Lin Lei with wide eyes.

Seeing that the climax was about to be reached, Qiao Yan pointed the camera at Lin Lei.

Lu Yun faintly felt that something was wrong, but she couldn't say it.

Lin Lei snuffed out the cigarette in his hand, stood up, looked at Wu Liyang and Du Jun, and said slowly: "The room where the crime occurred is 708, which is on the seventh floor. If you want to enter and exit through the window, you must step on the air conditioner. It was a high-altitude operation, and the power went out that night, and it was pitch black, so it was impossible for the murderer to go around with a flashlight outside the house. Under such conditions, even the professional workers who are responsible for installing air conditioners do not dare to toss easily. ”

As soon as Lin Lei's words landed, everyone nodded frequently.

Yes, in the dark environment, you climbed out of the window on the seventh floor, stepped on the air conditioner, and then climbed into the deceased's room?

After the case is done, it is too dangerous to clean up the shoe prints on the air conditioner.

Maybe Spider-Man can do it easily, but if ordinary people want to do it, I'm afraid the possibility is very small.

Wu Liyang is the owner of a convenience store, and Du Jun is a freight driver, and they simply don't have the ability to enter the house through the window on the seventh floor in the dark.

Could it be that the murderer had a better way to get in and out of the deceased's room?

Everyone's eyes were focused on Lin Lei, but Lin Lei didn't look at anyone, but said to himself: "I don't know if you have heard of it, the more complicated it seems, the simpler the truth behind it." ”

Everyone looked at each other, and their minds were a little confused: What does Lin Lei mean by this? Could it be that the truth behind the case is very simple?

Lin Lei took out a cigarette from his pocket and lit it.

Lu Yun frowned and whispered, "Can't you smoke less?"

Lin Lei smiled: "I love to smoke, this habit is not good, but I am afraid that I will not be able to change it for the rest of my life." ”

"Smoke one less!" Lu Yun was dissatisfied.

Lin Lei shook his head: "...... who doesn't smoke and is inspired"

Lu Yun glanced at Lin Lei helplessly, and was really a little speechless: "Okay, you won." ”

Everyone began to think about what Lin Lei had just said.

In terms of modus operandi, it seems that it is very difficult for Wu Liyang and Du Jun to complete the crime by entering room 708 through the window.

So, who can complete the crime process more easily?

There seems to be only one answer!

Lin Lei took a deep puff of his cigarette and turned his head to look at Qiao Yan who was taking a camera: "I'll test you, how can you put an elephant in the refrigerator?"

Qiao Yan's face was full of black lines: "I said Lord Boss, is my IQ really so low?"

"Hmm-" Lin Lei shrugged, "Looks like you know the answer." Well, the paragraph is boring. So let me talk about this suspected murder case in a closed room, the so-called secret room, it's not bullshit -- the first step is to open the door, the second step is to kill someone, and the third step is to close the door. It's exactly the same as putting an elephant in the freezer!"

As soon as Lin Lei's words landed, Qiao Yan and Lu Yun's eyes immediately fell on Li Chengzhi, the waiter in charge of the key. The two exclaimed in unison, "Only he has the key, could it be him?"

Li Chengzhi's body trembled involuntarily......

Officer Li's mind was a little confused: "Advisor Lin, Li Chengzhi and Li Changxing have no grievances or hatred, and they have no motive to commit the crime at all-"

After a pause, Officer Li came to his senses and continued: "Adviser Lin, in fact, when you first ruled out conspiracy to commit crimes, I wanted to ask, why did you exclude conspiracy to commit murder from the motive, but you did not rule out Li Chengzhi, who also had no motive for committing the crime? If there is no motive for conspiracy to commit murder, then Li Chengzhi has no motive for murder!"

Everyone had the same doubts and stared at Lin Lei tightly.

Lin Lei flicked the ashes of his cigarette and said lightly: "This is the interesting thing about this case -- the person who should be most suspected in this case is not Li Chengzhi, who has the spare key to the hotel? However, Li Chengzhi has no motive for committing the crime!"

Everyone showed a look of surprise, and Officer Li was even more dizzy by Lin Lei: "If Li Chengzhi has no motive for committing the crime, then he is the least suspected-"

Lin Lei shook his head: "Officer Li, you are thinking by inertia, or qualitative thinking. But there is no problem with the saying that anyone who commits a crime must have a motive. However, many times, the criminal's motive for committing the crime is very strange, and you are easy to ignore it selectively. So if the motive cannot be explained, then the suspect must be excluded from other aspects. Unfortunately, Li Chengzhi is the most suspicious one in any other way except for the unknown motive for committing the crime. In my mind, Li Chengzhi can't even pass the first level!"

Lu Yun was the first to react: "Indeed, Li Chengzhi is the most likely to commit a crime, and he has a spare key to room 708." ”

After a pause, Lu Yun was a little unsure: "Lin Lei, everyone knows that Li Chengzhi is the most suspicious, but just because he has no motive to commit the crime, he feels that he is not as suspicious as the previous ones." You will never parachute in for a reason, saying that Li Chengzhi and Li Changxing have a grudge, right? Or Li Chengzhi killed him because his girlfriend split his legs? This is impossible, because the special case group has already investigated very carefully, and Li Chengzhi and Li Changxing have no grievances. ”

Lin Lei smiled, glanced at Li Chengzhi, and then turned to Lu Yun and said, "You are my old passenger, you still don't understand how I solved the case?" Li Chengzhi's motive for killing must be there, and it is in the file-"

Lu Yun gasped: "It's in the dossier, why didn't I find ......?"
