Lao Lu tilted his head sideways, looked at the roller shutter door hanging in the air, and asked me puzzledly: "What is the reason?" ”

I said: "At that time, the time of the incident was the time when the deceased Kang Yajuan was anxious to go home and reunite with her husband, so Kang Yajuan was already preparing to close the shop. Then I can assume that Kang Yajuan was in a hurry to close the store at this time, but this roller shutter door has always been faulty, if you want to close it, it is difficult for Kang Yajuan to do it alone, plus she is eager to go home, Kang Yajuan asked a male customer who has not left the store to help pull down the roller shutter door. And this male customer is the murderer in this case. ”

Lao Lu pondered for a while, and continued to ask: "Even if the male customer killed Kang Yajuan, I still can't understand why the crime was committed behind the cash register in the store?" ”

I said, "That's a good explanation. That is, the male customer had already selected the goods, but he did not pay, Kang Yajuan asked the male customer who had not paid at this time to help pull down the roller shutter door in half. Because the roller shutter door would get stuck when it was pulled down to about 30 cm, the male customer helped pull it through the 30 cm position. I estimate that the height of the roller shutter door is to retain the height that can be bent in and out. After that, the male customer and Kang Yajuan both went to the cashier to prepare for the checkout, but they didn't know what the reason was, so the male customer killed Kang Yajuan. ”

Lao Lu frowned, looked at the rolling shutter door that fell thirty centimeters stupidly, and muttered, "Did the case really happen like this?" ”

I stood outside the shop with my waist crossed, looked around, and saw no other jewelry stores. In the interval between Lao Lu's thoughts, I visited the children's clothing store and women's clothing store next to the jewelry store. Sure enough, every time Kang Yajuan closes the roller shutter door, she will ask them to help, Kang Yajuan herself has said many times that she will ask the landlord to repair the roller shutter door, but the landlord has not repaired it for a long time.

When I returned to the jewelry store, Lao Lu was standing in front of the store smoking a cigarette, and he said, "We have investigated the surrounding area before, and we have not seen any suspicious man wearing a rosary on his hand. ”

I said: "I have thought about this, you think about it, do we have the habit of shopping around, then we can investigate from this kind of similar jewelry store, maybe the suspect appeared in other jewelry stores before the crime." ”

Lao Lu nodded, and we immediately pulled down the roller shutter door and investigated the surrounding jewelry stores.

We found a jewelry store closest to Kang Yajuan's jewelry store. This jewelry store called Winter Snow House is about 800 meters walking distance from Kang Yajuan's jewelry store.

The Winter Snow House jewelry store is obviously much larger than Kang Yajuan's jewelry store, and the goods are more abundant, and the decoration in the store is also more exquisite. Most importantly, this store is a real downtown storefrontage.

So did the killer ever come and go in this store?

We conducted an in-store survey and found surveillance probes both inside and outside the store. I counted carefully, there are a total of 11 monitoring probes in the store, 1 at the door of the store, a total of 12 monitoring probes, and the monitoring range covers almost every corner of the store.

With the permission of the manager of the jewelry store, Lao Lu and I retrieved the surveillance video of the jewelry store.

On the day of the crime, I estimated that the time when the killer might appear at the Winter Snow Room jewelry store was between half past five and half past six in the afternoon.

So I carefully checked the video footage for a period of time to see if a man with a rosary on his hand had ever entered the jewelry store.

At 6:17 p.m., a young man with a flat head and a blue short-sleeved shirt came into my sight.

About two seconds into the video of the man appearing in front of the store, I noticed that he was visibly wearing a black object on his left wrist. Although his hand was swinging, and the video was too short and not very clear, I couldn't be sure what he was wearing on his wrist. But during this time, he was the only one who came and went with an object on his wrist. So this young man in a blue short-sleeved shirt became my key suspicion.

In the 11 surveillance footage of the store, I found that this suspicious man actually appeared in the surveillance. However, judging from his behavior, he is carefully selecting goods. Judging from his actions and looking at the price tags of the goods, he should pay the most attention to the price of the goods. And judging from the goods he selected and observed, he chose things like stuffed animals, small porcelain cups, exquisite ornaments, and women's fashion hats. It seems that the man is preparing a gift for the woman.

In the surveillance footage, I was watching his left wrist all the time. Although the surveillance screen is not very clear, it can be determined that on his left wrist, he is wearing a string of rosary beads, and it is a single rosary bead with a large string of prayer beads. This is very consistent with the rosary found at the scene of the crime, and his suspicion has increased again.

Lao Lu looked at the surveillance video and said loudly: "Ouyang, don't look at it, this person is too suspicious, I'll ask the boss to see if she has any impression of this person." ”

I nodded in agreement.

In fact, we can't meet the owner of the Winter Snow House jewelry store, because this is a national chain of jewelry stores, and the owner is not in this store. Of course, it is useless to find the boss, what we need to look for is the clerk who has been in contact with this suspicious man. I've seen it on surveillance that there is such a clerk who has spoken to suspicious men.

Lao Lu asked the store manager to identify and see who the clerk who had talked to the suspicious man in the video was, and the store manager quickly identified the female clerk and said that this clerk was the flower of their store, which was easy to identify.

It just so happened that the 'shopgirl' was at work today, so we found her easily.

'Shop Flower' does have a bit of a look, but it is only a little bit more beautiful than a few employees in the store, and if it is put on the street, it is also a passerby. So I'm still a little disappointed.

At this time, the surveillance screen has been paused by me, I pointed to the man wearing a blue short-sleeved shirt on the screen, and said to the 'shop flower': "Do you have any impression of this man?" ”

'Shopflower' squinted at the phoenix and leaned in front of the screen to take a look, it turned out that this 'Shopflower' was a little short-sighted. I frowned, if she was too short-sighted, would she not be able to see the suspicious man's features?

The 'shop flower' spoke, and the voice was very soft, which could add a lot of points.

"Well, I have the impression that it was a young boy who said that he came to buy a birthday present for a girl. He picked a lot of goods, but in the end he didn't buy them because of the price. Hmph, it's not interesting for a boy like this, buy a birthday gift for a girl, and choose a bargain. ”

I said, "What are the characteristics of this boy, do you see clearly on his wrist?" Is there such an extra-large rosary? As I spoke, I drew a circle with my right thumb and forefinger.

'Shopflower' said: "Yes, yes. I was very impressed with the rosary, but I felt that it was a little out of place for young people to wear it. ”

Of course, the 'shopkeeper' didn't know, and this kind of incompatibility was the key to solving the case.

I continued, "Describe the man's physical characteristics, such as height, appearance, accent, and clothing characteristics. ”

'Dianhua' thought for a while and said, "This person is very thin, about one meter tall and in his early seventies, not too tall." He looks quite delicate, and his skin is not too dark. The accent is just a local. Oh, by the way, his blue short-sleeved shirt should be a kind of overalls. The word 'Jianglin' was also written on his chest. ”

I hurriedly asked, "Is it the river of the Yangtze River and the forest of the forest?" ”

'Dianhua' nodded and said, "Well, it's these two words." ”

"Okay, thank you!" As soon as I finished saying thank you, I quickly took a photo with my mobile phone on the display screen of the surveillance computer, and then rushed out of the Winter Snow House jewelry store, followed by Lao Lu. Of course, we all know that the next destination is 'Jianglin Machinery Factory'.

Jianglin Machinery Factory is located in Wuqiao, is a veteran enterprise in Wanzhou, the older generation of Wanzhou people have heard of this machinery factory more or less.

Lao Lu drove the police car and came to Jianglin Factory at a gallop.

At this time, the factory was working, and the roar of the machine came and went.

We came to the personnel department in the factory, the head of the personnel department is a fat male man with black-rimmed glasses, his posture, this weight, I estimate that it is 200 pounds.

Because this personnel section chief is quite fat, he gives people the feeling of being cute and cute. Although he was in his forties, he was so fat that there were almost no wrinkles on his face, and he smiled like a Maitreya Buddha.

"Mr. two police officers, I don't know what to do when you come to the factory?" The head of the personnel section pretended to be elegant when he opened his mouth, which made me feel a little pretentious. However, this kind of person is also a professional habit formed because of long-term experience in society, and I don't mean to look at him with colored glasses, but I really don't like this kind of person.

After he finished speaking, the cigarette was already handed over.

Lao Lu opened his fat palm and said, "We are on official duty and don't smoke." ”

The head of the personnel section smiled, took back the Chinese cigarette, and said with a smile: "It's easy to say, I don't know if there is anything that can help the two police officers?" ”

I don't want to talk to him too much, as long as this kind of person does not involve his interests, it is easy to find out the news. So I put my phone in front of him, showed him a photo of the suspect, and said, "The photo is not very clear, it was taken on the computer screen, you see, do you have any impression of this man?" ”

The head of the personnel section took my mobile phone with fat and white hands, looked at it carefully for a while, and said, "Well, the clothes this person is wearing must be from our factory." But whether this person is from our factory or not, I can't say for sure, I really can't see it clearly. And some family members will also wear the work clothes in our factory as casual clothes. ”

I looked at the HR chief and said, "Yes, family members may wear factory uniforms as casual clothes, but I guess they are all elderly people." Would a young man in his 20s wear such a short-sleeved shirt as his usual casual clothes? I'm sure this person is an employee of your factory. Do you remember that he used to wear a string of rosaries on his left wrist? ”

"Oh, there is an impression, there is an impression, this kid has been criticized by me. I criticized him, saying that the rosary was so big, that if it fell off at work, the rosary would fall into the machine, and maybe there would be some big basket. He didn't wear it when he went to work after that, and I don't know if he usually wore it or not. ”

The situation reported by the head of the personnel section was very important, and I quickly asked, "What is his name?" Can you find him right away? ”

The head of the personnel section showed a look of sudden realization and said: "His name is Song Chengbo, no wonder he left a few days ago, it turned out that he committed something outside." Comrade policeman, what did he do? ”

I didn't pay attention to the question of the head of the personnel section, but quickly asked, "Give me his contact information and address information, hurry." ”

The head of the personnel section then shook his bloated and fat body and walked to the desk and extracted Song Chengbo's information from the computer.

Of course, the contact number in Song Chengbo's profile has been turned off, but his home address is very detailed, and it is located in Wuqiao Tianxing Village.

Based on the address in the profile, we found Song Seungbo's home.

When our police car pulled up to the side of the road outside Song Chengbo's house, I saw an old farmer with a sad face and white hair walking out of the gate of his two-story blue brick house.

As he walked, he beckoned to us with his trembling right hand, and his mouth trembled and chanted: "We surrender, and my family surrenders." ”

It turned out that this old man was Song Chengbo's father, who was 65 years old this year, and he had a total of three sons, and this Song Chengbo was his youngest son.

Under the leadership of the old man, we came to the second floor of this small building.

The old man pushed open a wooden door, and a sour smell came from the door.

When I walked into the room, I saw a young man curled up in a corner of the bed near the wall, shivering.

This young man is none other than Song Chengbo. Since the crime, he has taken refuge in this room and has never come out.

In this room, Song Chengbo confessed all the facts of the crime.

It turned out that the day of the crime was Song Chengbo's girlfriend's birthday, so Song Chengbo happily went to buy a birthday gift for his girlfriend. But when he came to Kang Yajuan's jewelry store to buy gifts, he received a text message from his girlfriend, and the text message was just five words, 'Let's break up'!

Song Chengbo hurriedly dialed his girlfriend's phone, but the phone was turned off, to be exact, Song Chengbo's mobile phone number should have been blocked by his girlfriend.

This kind of breakup without warning was a big blow to the young and deep-rooted Song Chengbo. He was almost stunned in the jewelry store.

At this time, Kang Yajuan was anxious to close the store and go home, so she urged Song Chengbo a few words. Song Chengbo's resentment and grievances at this time had nowhere to vent, so he squinted at Kang Yajuan and found that Kang Yajuan was a little beautiful, even more beautiful than his girlfriend. So under the emotion of resentment, evil thoughts arise.

Song Chengbo, under the urging of Kang Yajuan, did not leave the jewelry store, but deliberately looked east and west to delay time.

Kang Yajuan was helpless, she couldn't drive away the guests, so she had to pull the shutter door first, but the shutter door was broken, and she couldn't pull it down by herself. She was also worried that the man in the store had unclean hands and feet, and when she went out of the store to find someone to help pull the shutter door, she stole his own things. So I simply asked the man in the store, that is, Song Chengbo, to help pull the roller shutter door.

Song Chengbo felt that this was an opportunity, so he readily agreed, and pulled down the roller shutter door, and deliberately pulled it very low.

After that, he took a hat and said that it was a checkout.

So the two walked to the cash register inside the jewelry store. At this time, Song Chengbo was fierce, hugged the thin Kang Yajuan, and pressed him to the ground, ready to sexually assault her.

Kang Yajuan's frantic resistance not only scratched Song Chengbo's face and arms, but also tore off Song Chengbo's beloved rosary.

Annoyed and angry, Song Chengbo went completely crazy, grabbed the knife that Kang Yajuan used to peel the fruit under the cashier, and inflicted fatal injuries on her.

The murder that happened in the jewelry store was completely solved. A young person who still has Buddha thoughts in his heart actually committed such an extreme vicious murder when his feelings were frustrated.

Whether it is a Buddha or a demon, just in the blink of a thought. Perhaps the moment the rosary was broken, he fell into the path of demons, and never recovered.
