The case analysis meeting is still continuing, and after the clues of all parties are summarized, the police have a preliminary understanding of this case.

But everyone still couldn't figure out one thing, the deceased had been killed at half past four, why the time of death was at five o'clock, and what happened in the middle of the half-hour difference.

Mo Yufei thought for a while and analyzed: "Maybe the murderer hit the deceased on the head with a blunt object at half past four, causing him to fall unconscious, and then committed theft in the house. But the deceased woke up at five o'clock, and the murderer committed a second assault, covering his mouth and nose, and finally suffocated to death. ”

Su Simeng on the side nodded again and again, and agreed: "There is indeed such a possibility, so that all the trace examinations and autopsies will correspond." ”

Ling Zizhen also spoke at the right time, adding: "The policeman said that the deceased left the company at three o'clock, and the journey was only twenty minutes, and the deceased arrived home at four o'clock." The reason was found in the next half hour, but what about the first half hour? ”

Lu Ke twisted his fingers, stared at the photos on the big screen, pondered for a moment, and muttered, "There are no signs of damage to the doors and windows...... Acquaintances committing crimes? Burglary? Burglary? Is it the key to open the door or the dead to open the door? ”

There are still too many unknowns in this case, and there are too many possibilities.

Lu Ke paused and ordered: "Investigate the bidding project half a year ago, as well as the social relations of the deceased, this case is likely to be a revenge murder caused by commercial conflicts." In addition, the scene of the crime was in a residential building facing the street, although the monitoring was not complete, but the time of the crime was in the evening, and there were many people coming and going on the street, and witnesses may be found. Send out all four exploration teams to expand the scope of the survey, and investigate the surrounding neighbors and merchants one by one to see if they can get any clues. ”

After speaking, Lu Ke stood up: "I'm going to the crime scene again." ”

Standing downstairs at the scene of the crime again, it was already dusk, the sun was setting, and the sky and earth were red.

Pedestrians on the street come and go, busy, looking forward with their heads bowed, without the slightest intention of waiting.

In front of me is a row of residential buildings facing the street, the first floor is full of merchants, and the second floor and above are residents, and every three buildings are divided into a district, sharing an entrance.

In other words, if you want to enter the scene of the crime, you can only enter the door of the building by walking through the intersection in front of you and bypassing the back of the building.

This is the only entrance and exit to the crime scene, and no matter who the murderer is, as long as he enters and exits the crime scene, he must walk through here.

If you want to find witnesses, it is impossible to start with passers-by, and you must find someone who can observe the entrance and exit for a long time.

Lu Ke stood on the side of the street, looking around, and finally fixed his eyes on a roadside stall not far away.

This roadside stall is an extension of a small tricycle, and its main business is bicycle repair and key distribution. In the early years, such stalls were everywhere, but now with rapid urbanization, they are gradually disappearing.

Lu Ke calmed down, beckoned Mo Yufei beside him, and went over to have a look.

The stall owner was an old man with dark skin and a somewhat old look. Although he is thin, he looks like he has a kind of sturdy body that has worked all year round and has been weathered.

He sat on a chair and stared at the street, looking at all kinds of people, very pleasantly.

Seeing Lu Ke and Mo Yufei walking towards the stall, the old man's eyes showed light, he sat up straight, and asked, "Repair the car or get the key?" ”

With a thick smile on his face, Lu Ke walked up to the old man: "Uncle, do you set up a stall here every day?" ”

The old man also smiled and nodded: "I come every day." ”

Lu Ke did not rush to reveal his identity and go straight to the topic, but chatted with the old man.

The old man is very talkative, but more time is alone in front of the empty stall, this time someone came to chat, and he was very happy.

"Uncle, how many years have you been repairing cars?" Lu Ke asked casually.

Hearing this question, the old man suddenly cheered up, and his expression instantly became excited: "I have been repairing cars all my life, I followed my father to learn to repair cars when I was a child, at that time there were not so many bicycles now, what mountains, highways, speed changes, dead flights, none of these." ”

Lu Ke smiled and agreed: "It's all twenty-eight bars." ”

The old man waved his hand and said, "Twenty-eight? It's too late! The first thing I built was a flying pigeon bike! Now the group of car repairers have no technology, they don't understand anything, they just fool people. Earlier there was a stall here, and the man didn't know how to fix the car at all, and then he broke the person's car! ”

"Uncle, you have been repairing cars for so many years, do you remember all the people who come and go?" Lu Ke asked again.

The old man nodded, showing a smile with deep meaning: "I remember, I remember, and I still remember, you came a few hours ago." ”

After hearing this, Lu Ke and Mo Yufei were both stunned.

The old man pursed his lips, his eyes narrowed, and continued: "And I also saw that you and those policemen seem to be together. ”

Lu Ke smiled awkwardly, noncommittal.

"Tell me, is there anything I can do to help?" The old man turned his head to look at Lu Ke and asked lightly.

Lu Ke nodded, and his tone became serious: "From three to five o'clock in the afternoon, has anyone ever entered this gate?" ”

After Lu Ke finished speaking, he stretched out his finger and pointed, and the gate was not far away. Sitting in front of the stall, you can clearly see the situation of the gate.

"Who? There are quite a few people who go in, all of them are residents in this neighborhood, and there are many people I look familiar with. The old man didn't think so, and said very proudly.

Lu Ke thought for a while, organized the language, and asked, "Are there any strange people who have come in and out?" Is it the kind of person who walks fast, looks nervous, and walks in a hurry? ”

The old man took a deep breath, recalled carefully, and suddenly said, "I seem to have seen a person in dark green overalls go in." I saw that he was sneaky, not like a good person, and he was not very familiar with the road conditions here, and he turned around several times in front of the building, so I was more impressed. ”

Hearing this, Lu Ke instantly became alert, and Mo Yufei, who was opposite him, asked, "Dark green overalls?" What is the company? ”

The old man was a little embarrassed and shook his head: "Then I don't know, it feels like he's here to repair, he is carrying a square bag cross-body, which seems to be tools such as pliers and hammers." ”

"Pliers?!" Lu Ke was stunned for a moment.

"But it's only the color of the clothes, I don't know what company it is......" Mo Yufei was a little anxious for a while.

Lu Ke stood up straight and looked around, there was a big road in front of the building, and there were many intersections at both ends.

He twisted his fingers and suddenly said, "No matter where this staff member came from, since he is not familiar with the road conditions here, he must not be from this neighborhood." If you want to come here, you must have a means of transportation, and if you investigate the various traffic intersections around you, you will definitely be able to find traces of this person. ”
