Women will always tell men who go out not to pick wildflowers on the side of the road. Indeed, some wildflowers can be fatal when picked at will. However, in my detective career, there was such a case, but it was solved because the murderer picked a lavender plant at random.

It was June, and the temperature in Wanzhou had climbed to more than 30 degrees, which was no different from summer.

But on this hot day, a homicide occurred.

When I received a call from Lao Lu and rushed to the scene, it was already 7:10 p.m.

The scene of the murder was a massage parlor on the side of the road. In my career, the chances of homicide in such places such as massage parlors and foot washing parlors are quite high.

A cordon was set up outside the massage parlor, and the lights of the two police cars were still flashing.

I first looked at the outside of the massage parlor and found that there was no camera to cover it. Then this case will inevitably increase a certain degree of difficulty.

In fact, I hope that this kind of difficulty exists, because the emergence of high technology has made it easier and easier to solve cases. Sometimes, it is only necessary to implement some prescribed procedures step by step, and the case can be solved smoothly.

Of course, Lao Lu will not call me for those cases, and my value lies in solving those bizarre and bizarre cases.

In fact, I also know that even without my existence, Lao Lu and his colleagues can solve the case. However, the reason why Lao Lu asked me to be a consultant to the criminal investigation team was because I liked my efficiency and speed in solving cases.

Fortunately, so far, I have not lived up to Lao Lu's expectations of me.

Without further ado, I entered the scene of the crime.

Once inside, I took a look around the first room. Why do I say the first room? Because there was another door in my field of vision, and there was a flicker of flashing lights from time to time in that door, I knew that the crime scene must be in the back room.

However, it can't be said that there won't be any clues in the outside room, so when there are more investigators in the back room, I will first investigate the outside room.

The room I was in was neat, there were no signs of a fight, no corpses. There are only three massage tables and a TV.

Behind me was a silver-gray curtain, and I smelled a smell of blood in the outhouse, so it is conceivable that the amount of bleeding from the deceased was relatively large. So when the murderer leaves, will there be blood stains?

So I first checked the curtain outside the house, because the curtain blocks the whole door, and if you want to get out, you have to lift the curtain, so will there be blood stains on the curtain?

Can I use the word lucky? Because on the curtain of the door, blood was indeed found. The blood stain had a wipe mark and was wiped from the finger to the place of the door curtain.

Based on the location of the bloodstains, I made another judgment. A normal person raises his hand to open the curtain, and the highest point of his fingertips is almost parallel to his eye line, and based on this feature, I determined that the height of the person who left the blood stain was between 173 cm and 175 cm.

I looked at the ground again, and in the corner of the door to the back room, I found a lavender.

This lavender is about 20 centimeters long, and its petals are slightly peeling, but the color is still relatively bright, indicating that the picking time is not too long.

I crouched down, frowned, stared at the lavender for about five seconds, then stood up and looked around the room again.

I didn't see a vase or a cup or anything like that, so this lavender wouldn't be in this room.

Could it be something from the back room?

After both the forensic and investigation teams came out of the back room, I finally entered the back room.

Lao Lu held his chin in his right hand, looked at the female corpse on the bed and said, "The identity of the deceased has been confirmed, his name is He Yulian, and she is the female boss of this massage parlor. According to the autopsy temperature test, the deceased died at about 4:30 p.m. today. The cause of death was death from being stabbed in an artery in the neck with a pair of scissors. ”

I nodded, looking around the room. The house here is smaller than the one outside, but it is much more beautifully furnished.

There is a portrait of a sunflower on the wall, and the TV inside the house is an LCD TV, which is different from the old-fashioned TV outside. The massage table is also twice as large as the one outside.

This room also leads to another room. I went to the other room first, and it was the kitchen, and in front of the kitchen was the bathroom.

Of course, many of the houses in this kind of street-facing shops look like this. Such a design is convenient for merchants to operate and live.

When I got back to the back room, I didn't find the vase, so I was able to be sure that the lavender from outside the house had been brought in from the outside, but whether it was brought in by the murderer or the deceased. However, DNA testing technology can be used to determine the residual cellular DNA on the lavender to determine who brought the lavender.

As for why it was determined who brought the lavender, I'll explain why later.

The gaze fell on the deceased. The deceased was fair-skinned, had dyed yellow hair, had light make-up on his face, and was approximately 35-38 years old.

Judging from the way she dresses, this woman is relatively fashionable at this age.

The bed was covered in blood, and there were signs of struggle, especially near the deceased's head and neck, where there was a lot of blood flow.

This shows that the deceased struggled after being mortally wounded.

I looked at the deceased's neck again and found that there was not just one wound, but two deeper wounds.

I can be sure that the killer first stabbed the deceased once, and then stabbed the deceased twice in the neck while he was struggling with his injuries.

Judging by the messiness and blood splattering of the scene, I am convinced that this is the first scene of the crime. And Lao Lu told me that the murder weapon, that is, an old-fashioned pair of scissors, the head of the scissors was very sharp, and it had been placed in the evidence box by the investigators.

I nodded and continued to check the scene.

I found a very thin gold necklace in the collar of the female corpse. The chain was broken by the woman when she was stabbed in the neck and was dying and struggling.

The woman wore gold rings on her fingers and gold earrings on her ears, both of which were intact. At the same time, next to the TV cabinet, there was a green lady's satchel with a wallet, which contained more than 3,000 yuan in cash and various bank cards and documents. Next to the satchel, there is also a mobile phone.

Then according to these circumstances, it can be seen that the murderer is not seeking money.

The female corpse is fully dressed and has not been sexually assaulted, so the murderer is not seeking lust.

It's not a desire for wealth or lust, so will it be a vendetta?

This is a possibility, because the deceased was stabbed three times in the neck, which was obviously intended to take his life.

So Lao Lu and I agreed that vendetta was the most likely.

I also found cigarette butts at the scene, which is a common smoke in Chongqing, Chaotianmen. The retail price of cigarettes is generally $6. I don't think the economic conditions of people who smoke this kind of cigarette are very good.

At the same time, at the junction of the kitchen and the back room, a footprint was also found. Judging by the size of the footprints, the height of this person is about 173 cm, indicating that the footprints and the blood stains on the previous door curtain should have been left by the same person.

And why did the murderer leave footprints in this location, I guess the murderer went to the kitchen and washed his hands with the kitchen faucet.

This conjecture was later confirmed, as blood residue was extracted from the kitchen sink drain.

The investigation at the scene was basically over, and the criminal investigation team quickly made an investigation report.

In the inquest report, the bloodstains on the curtain did not belong to the deceased, but to a man. The DNA data extracted from the man's blood stains were compared with the DNA data on lavender and cigarette butts, and they were in perfect agreement. Unfortunately, there is no matching DNA data in the national DNA database.

This means that the man had fought with the deceased and was bleeding from his injuries.

And the lavender in the house was also brought into the massage parlor by the murderer.

In the investigation report, it is reflected that the background of the deceased He Yulian is very complicated.

He Yulian is 36 years old this year, but she has had four marriages and three children. Two of the children followed her ex-husband, and He Yulian raised the children with her fourth husband alone.

From this information, I express my sympathy for He Yulian and her children. And I feel that He Yulian's marriage is bumpy and her life is not easy, which makes people sigh.

And according to the investigation, He Yulian also has a boyfriend named Feng Mincheng, who is 26 years old this year, ten years younger than He Yulian.

With such a big age difference between sisters and brothers, will this Feng Mincheng be a murderer?

Lao Lu quickly locked on this Feng Mincheng.

Through investigation, it was found that Feng Mincheng's family was extremely opposed to him and He Yulian being together, and there were two main reasons for the opposition. The first is that He Yulian's age is indeed too different from Feng Mincheng, and the second is that He Yulian still has a four-year-old child.

However, even though the family objected, Feng Mincheng still lived with He Yulian.

This Feng Mincheng runs a small grocery store for a living, and his shop is not on the street or in the downtown area, so the business is bleak. The main source of income for the two is still supported by He Yulian.

Through the investigation of the neighbors of He Yulian's place of residence, it was learned that Feng Mincheng and He Yulian did not have a good relationship, and often quarreled and fought in the middle of the night.

So could it be because the two had some disputes, and Feng Mincheng killed He Yulian in a fit of anger?

After summoning Feng Mincheng, we were disappointed.

First of all, Feng Mincheng's height, he is only about 1.65 meters, which does not match the height of the murderer I deduced.

The second is that Feng Mincheng is not a smoker.

The third and most important point is that we found the murderer's DNA at the scene, which is completely inconsistent with Feng Mincheng's DNA.

The suspect who seemed to be the most likely suspect before was ruled out like this, so who else could it be?

Feng Mincheng provided us with a clue, that is, He Yulian's ex-husband is likely to be the murderer of He Yulian. Because her ex-husband has always wanted to fight for the custody of her son, but because of work problems, he has not been able to compete with He Yulian.

The ex-husband of He Yulian in Feng Mincheng's mouth is He Yulian's fourth husband, Zhang Sui'an. Zhang Sui'an is a seafarer who has been adrift on the Yangtze River for a long time, and it is difficult to take care of his family. Because her husband was away for a long time, the restless He Yulian gave Zhang Sui'an a green hat, and Zhang Sui'an divorced He Yulian in a fit of anger.

It is precisely because of Zhang Sui'an's work that he did not fight for the custody of his son. Therefore, even if he is divorced, he still has had conflicts with He Yulian many times, and the purpose is to get the child back.

And in the process of making conflicts, he also had a big fight, and because of this incident, Zhang Suian was also detained.

Then Zhang Sui'an's criminal suspicion has been qualitatively improved.

However, after the investigation was carried out in depth, we were disappointed again.

We did not find Zhang Sui'an, and according to Zhang Sui'an's unit, Zhang Sui'an went out with the ship a week ago and should be in Shanghai now. His exact location was confirmed by the captain of the ship he was on, and Zhang Sui'an was not in Wanzhou at all when He Yulian was killed.

Another suspicious figure was ruled out.

This is how we can solve the problem, in the process of detection, we will take thousands of paths, but in the end, only one path can be taken. Therefore, we must not be discouraged, nor can we retreat in the face of difficulties, and the only way to catch the murderer is to rise to the occasion.

The case seemed to be at a dead end, but I used the lavender I found at the scene of the crime.

This kind of lavender is not rare in Wanzhou City, according to the criminal investigation team's investigation of the entire Wanzhou City, it was found that there are six gathering places for this lavender, but only three pedestrians are likely to pick it.

Moreover, the lavender flower bed in the Peace Square is relatively close to the scene of the crime, so I judge that the source of this lavender is the Peace Square.

So now we have to carry out a lot of investigation work, and the direction of the work is to check whether there is a person picking lavender near the Peace Square and near the crime scene, and this person has appeared near the crime scene.

Unfortunately, the surveillance in the Peace Square does not directly see the lavender parterre, but it can see the branch road that comes out of the lavender parterre.

Lao Lu divided the criminal police into two groups and began to work overtime to find clues from the surveillance video.

I also threw myself into this heavy and intense work.

Two days later, I saw a suspicious figure on surveillance near the scene of the crime.

The man, a middle-aged man, walked up to a brown sedan parked on the side of the road and looked at the car as if he was interested in it.

While he was watching, he also touched the body of the car with his hand. This move struck me as strange, and I deduced that this person's move seemed to be testing the car's burglar alarm function.

However, the man quickly left the vehicle, and it seems that he is not the owner of the car.

This person looked left and right as he walked, as if he did not have a specific destination, and was aimless.

He stopped when he walked to the bottom left corner of the surveillance video, his hands on his hips, and he seemed to have some discomfort in his lower back.

Just as he crossed his waist, I saw that there was something wrong with the shadow behind him, because there was still a striped shadow on his left hand in the shadow.

I looked at it five times, and I was sure that he had a strip of object on his hand. It's just that because the surveillance screen is blurry and the angle is a problem, you can't see anything if you look directly at this person's left hand. But looking at the shadow, you can see some clues.

The lavender found at the scene of the crime, if viewed from a distance, is in the shape of a stick. In surveillance, it looks like a chopstick.

Then in the shadow of this person, there is such a shadow of chopsticks in his left hand, so I conclude that he may be holding lavender in his hand.

But I can only say here that it is possible, not 100% certain, because it is still possible that he is holding something else in his hands.

To prove my suspicions, I mobilized all the detectives to look for this person under surveillance in the Peace Square.

The hard work paid off, and this person was indeed found in the Peace Square, and in this person's hands, he could vaguely see what he was holding.

The moment the man got on the bus, his hand was raised, and a little purple could be seen on the screen. We know for sure that he has lavender in his hands.

And the bus on which this person got on, the route traveled by this bus, was the bus stop near the scene of the crime.

Extracting the surveillance of the bus stop, sure enough, this person was found. After he got out of the car, he wandered all the way and entered the surveillance near the crime scene, which is the same surveillance where I found his traces.

And this surveillance is only 20 meters away from the crime scene, but the direction it covers is exactly the opposite of the crime scene, so you can't see who has entered the crime scene.

I took a closer look at the person's behavior in the surveillance.

He crossed his hips, looked to the left front, and then walked away from the surveillance frame with a firm and purposeful step.

I speculated that after walking some distance, this person felt a little tired from his waist, so he stood on the side of the road and crossed his waist, and at the same time, he saw a massage parlor not far away, so he walked into the massage parlor to consume. Of course, he also brought the lavender into the massage parlor by the way.

Now we can basically confirm that it was this person with lavender in his hand who killed He Yulian, the female owner of the massage parlor.

So it seems that it was just a killing, so how did this killings happen? The suspect must be found.

Because of the surveillance video, Lao Lu issued a wanted warrant to the society, hoping that the masses would report it.

On the third day of the warrant, a woman in her 40s and a man in her 40s came to the police station and turned herself in.

The man in his 40s who turned himself in was the murderer of He Yulian.

The murderer's name is Jiang Youzhao, a local. He has been working in other places and is doing car repair.

Due to family reasons, he only returned to Wanzhou a week before the incident. On the day of the crime, he came out to look for a job, and after looking for a day but did not find a suitable car repair shop. Just when he was tired of walking, he saw the massage parlor opened by He Yulian.

Jiang Youzhao originally had a problem with his waist, so he went to He Yulian's massage parlor for a massage. But after the massage, Jiang Youzhao felt that He Yulian's massage techniques were very poor and unprofessional, so he was unwilling to give the 80 yuan he had negotiated before, and was only willing to give 50 yuan.

Because of the difference in the price of 30 yuan, the two had an argument, and He Yulian, a short-tempered woman, stabbed Jiang Youzhao's palm with scissors. Jiang Youzhao snatched the scissors in a fit of rage and stabbed He Yulian to death.

This unbelievable case was actually caused by such a reason, which made the entire criminal investigation team, including me, sigh and sigh.
