Lin Lei glanced at Li Chengzhi, who was on the evening shift, and asked, "After twelve o'clock, is there anything unusual in the hotel?"

Li Chengzhi shook his head blankly: "I locked the door of the hotel five minutes before the power outage, and after completing the routine inspection, I fell asleep on the folding bed at the service desk. Pen "Fun" Pavilion www.biquge.info"

Lin Lei took out a cigarette and lit it.

He didn't continue to ask, it was obvious that Li Chengzhi had been questioned by the police countless times, and if he had heard any sound in the middle of the night, the police would have told him a long time ago.

Wait, he slept to death?

Could it be......

Lin Lei's eyes deepened, and after thinking for a moment, he asked, "What time do you usually sleep on the night shift?"

Li Chengzhi thought for a while and replied: "If the power is not interrupted, I usually go to bed at about two o'clock in the morning." When you sleep, you also lock the front and back doors - well, there is a doorbell button in front, and you can press the doorbell if there are guests staying at the hotel. ”

Lin Lei then asked, "Do you usually sleep well, do you have a habit of getting up at night?"

Li Chengzhi replied: "The rule of our hotel is that the door can only close at two o'clock, and it is usually very sleepy at that time. I've always slept more deadly. As for getting up late, once in a while, it's not customary. ”

Qiao Yan listened carefully, for fear of missing something.

Lin Lei finally asked: "On the night of the crime, did you fall asleep?"

Li Chengzhi nodded.

After Lin Lei took a deep puff of his cigarette, he got up and came to the service desk, looking around, as if looking for something.

Qiao Yan and Officer Li both followed, and Qiao Yan asked with some puzzlement, "Boss, are you ......?"

Lin Lei stopped his searching gaze and shook his head: "It's nothing." Let's go to room 708 and have a look. ”

Lin Lei suddenly turned his head and said to Wang Xiqing, a tall day-shift waiter who had not spoken, "You take us up." ”

Wang Xiqing took the 708 room card and took Lin Lei and others to the elevator to the 7th floor.

Coming to the door of room 708, Lin Lei stopped and glanced at the room next to him.

Lin Lei looked at Officer Li beside him: "Officer Li, did you have any guests in the room next door to Room 708 on the night of the crime, did you hear any movement?"

This case happened more than 20 days ago, and Officer Li is the person in charge of the special case team, so he naturally knows a lot about it.

Officer Li frowned and said: "On that day, due to the advance notification to the travelers that there would be a power outage, there were not many guests staying at the hotel, including the deceased, and only 4 rooms were occupied. Room 706 is a person surnamed Wu, and room 710 is a person surnamed Du. And the opposite room 709 is a middle-aged man surnamed Wang. These people are card friends, and they came to stay at the Jiayuan Hotel after playing mahjong in another chess and card room. ”

Lin Lei added: "How old are they?"

Officer Lee replied, "They are all in their thirties, less than forty. ”

Lin Lei nodded slightly: "Officer Li, wait a minute, you can give me a copy of these people's materials, I believe the police must have made a detailed record, right?"

Officer Li immediately took out three copies of the interrogation transcript from his satchel and handed them to Lin Lei. After Lin Lei took a general look, he handed the materials to Qiao Yan: "Qiao Yan, you put it away, and I'll look at it carefully when I get back." ”

Qiao Yan took the materials and put them in her bag. Lin Lei made a gesture to open the door, signaling Wang Xiqing to open the door.

Wang Xiqing opened the door of room 708, and as soon as the door was opened, the police set up a cordon, Officer Li removed the cordon, and everyone entered the house together.

The room remained the same as the original crime scene, and the place where the victim was killed, that is, on the bed, were placed with several digital pieces of paper 12345.

This is a sign made by the police when they investigated the scene, and Lin Lei understood it at a glance.

Officer Li was afraid that Lin Lei would not be able to see it intuitively, so he took out a stack of photos from the briefcase he carried with him and handed them to Lin Lei: "Consultant Lin, this is a photo of the crime scene, you can take a look at it in combination with the scene." ”

Lin Lei took the photo and looked at it, and Qiao Yan also came over.

The deceased, a 36-year-old middle-aged man, was struck on the head with a blunt object while asleep.

Qiao Yan loves criminal investigation and reasoning, and has seen a lot of photos of corpses from newspapers or the Internet, so she doesn't feel particularly scared. She frowned, and made her own judgment: "Boss, the fatal wound of the deceased is in the head, and the cause of death is probably a head injury - you see, the skull has been smashed and dented. ”

Lin Lei's eyes narrowed slightly, and he nodded: "Yes, it's too ruthless." The deceased was a big fat man, tall and big—"

Qiao Yan's face was solemn: "The murderer should be an adult male, and he is strong. ”

Officer Li glanced at Qiao Yan appreciatively and echoed: "Yes, the description of the murderer in the bureau is a man in the prime of life between the ages of twenty-five and forty-five. ”

Lin Lei sighed "hmm" and was noncommittal.

After putting down the photo, Lin Lei began to take a closer look at the 708 room. This is a double room with only one bed. The toilet is on the right hand side of the door, and the whole room is about 20 square meters, which is a moderately priced room.

After more than ten days, the splattered blood stains on the wall have turned dark red, but judging from the form of the blood stains splashed on the wall, this is the first scene of the crime.

Lin Lei turned his head to Qiao Yan and said, "Qiao Yan, you record a video of the crime scene, record it in detail, I'll go back and take a look." ”

Qiao Yan nodded, took out a camera from her carry-on bag, and began to take pictures of the crime scene.

While Qiao Yan was taking pictures, Lin Lei walked to the bathroom.

It is a standard hotel restroom with a toilet next to the sink, and next to the toilet is a small shower cubicle surrounded by ground glass in a semicircle.

Lin Lei checked it and found nothing special.

Lin Lei looked up at the ceiling of the bathroom again, it was an ordinary sauna board, and it couldn't be easily removed, let alone hiding someone or something.

After checking the bathroom, Lin Lei came to the window of the guest room. It was a sliding window, which had been locked inside. Lin Lei opened the window and stretched out his head to look out.

Not far from the window is a small table for air conditioners, on which an old air conditioner is placed. Every room has an air conditioner, and the same is true for rooms 706 and 710 next door, which are not too far away because the rooms themselves are not large.

Lin Lei stared at the air conditioner slightly distracted, and there was a shallow layer of dust on the outside unit.

Lin Lei took out a cigarette and lit it.

Officer Li followed, didn't dare to disturb, and looked at Lin Lei with blank eyes.

After a long time, Lin Lei squinted his eyes slightly, and asked Officer Li, "Officer Li, the technicians should have investigated the situation outside this window at that time, right?"

Officer Li nodded and said, "Yes, there are no footprints or anything like that outside." Moreover, the windows were locked from the inside, and no signs of destruction were found. ”

Qiao Yan walked over with a camera and took a picture outside the window.

Everyone stared at Lin Lei, hoping that he could say something, but Lin Lei didn't say a word, as if he was thinking about something important......

PS: What type of case you have to have is a good detective novel. The plot setting of this case is that the murderer chooses one of the four, so let's choose one of the four. Every episode in Conan is a multiple-choice question, and it has been serialized for almost a thousand episodes. If you look at it slowly, this case must be very interesting. That's it.
