Restarting life by going to the countryside to support medical work

Chapter 420 Case Facts
"Zhi Hai, based on this alone, how did you connect this case with the case ten years ago?"

While Jin Zhihai was drinking water, Li Yancheng asked the doubts in his mind.

"Don't worry yet, listen to me."

Jin Zhihai raised his hand to signal.

"Based on what I just said, there is really no way to connect it to the series of cases from ten years ago. The reason why the Dianhai Branch reported it to us is because they found the conditions for merging the cases."

This time Li Yancheng didn't rush to interrupt and waited for him to continue.

"The chief of the Criminal Investigation Section of the Dianhai Branch found a relatively complete footprint about ten meters away from where the body was found.

I just said that he was a member of the special investigation team ten years ago, and the series of cases left a deep impression on him. So, after extracting the footprint, he directly compared it with the footprints extracted from the last case of that year. "

After hearing this, Li Yancheng understood that this footprint should be matched with one of the footprints extracted from the scene of the last case that year.

In the series of cases ten years ago, except for the victim in March, the other victims did not report the crime immediately after the incident, so there was no scene to speak of.

After the victim reported the case, the Dianhai Branch immediately protected the crime scene and extracted footprints from the scene.

Quite a lot of footprints were extracted, some were relatively complete, while others were incomplete, and no one could tell which one was left by the criminal.

In this case four days ago, the footprints found at the scene were matched with one of the footprints from that year, which was indeed a breakthrough.

"Are you sure that footprint is not yours?"

“Confirmed, after matching that footprint, the chief of Dianhai’s criminal investigation department immediately collected the footprints of all the police officers from the police station who had been to the scene that day, his colleagues in the department, and the forensic doctor, and ruled them all out.

That footprint was compared with that of an insider back then, and the possibility that it was an inside job can be basically ruled out.”

In the series of cases ten years ago, the task force also focused its attention on the insiders because it was discovered that the criminals had anti-detection methods.

After all, in those days, junior high school graduates could be called intellectuals, and 99 percent of ordinary people, even if they broke the law, had no concept of anti-reconnaissance, such as wearing gloves or foot covers when committing crimes, or deliberately cleaning up the traces they left behind.

The low crime-solving rate is due to the lack of scientific reconnaissance methods. The human wave tactic can sometimes work, but for Beijing, a city with a population of several million, it is still very difficult to rely solely on this to solve cases.

Just like in this series of cases, the criminals left bodily fluids in the victims' bodies, which have also been extracted. Unfortunately, in this day and age, these bodily fluids are of no use.

"Zhi Hai, is it possible that this person left Jing City due to some force majeure after committing his last case ten years ago? Is the reason he committed another crime recently because he is back?"

"We have thought of what you said. We have already started to arrange for the investigation of the educated youth who went to the countryside after March of the 21st year of the founding of the People's Republic of China. At the same time, we have also arranged to investigate those who were sentenced to labor and re-education through labor after March of that year."

"So why did you come to see me today?"

"It depends on whether you have time recently. This case is now in the hands of our Second Division. If you have nothing to do during this period, we will prepare to report to our superiors tomorrow and ask you to help us interrogate any suspects we may find in the next period of time."

"No problem for me." Li Yancheng agreed without even thinking about it.

When Jin Zhihai came over and mentioned this case, he had already guessed the purpose of his childhood friend coming here today.

Even without considering the brotherhood between the two, he would definitely take on this task.

If for no other reason, he just wants justice for the victims and for the criminals to be brought to justice and brought to trial.

"There is another type of person who should also be checked."

"What kind?"

Jin Zhihai just raised his hand to his mouth to take a puff of cigarette, but immediately put his hand down after hearing Li Yancheng's words.

"After March of the 21st year of the founding of the People's Republic of China, they were assigned to rural areas or other cities for some reason."

"Correct!"

"Pa" Jin Zhihai slapped his thigh excitedly.

"If you hadn't mentioned it, we would have really forgotten about this kind of person."

In the past two years, many people who had to go to the countryside or live and work in other cities for various reasons have been able to return home and are willing to return home.

The reason why they are willing to return home is that some people have already married and had children there, and have a good life and job, so some people are unwilling to come back.

Because it might be better for them to stay there than to come back.

There are quite a few people like this.

After the 21st century, a new policy was introduced for this group of people, which means that those who have left their hometowns for some reason can register their household registration back there and can also bring one child with them.

In fact, the main places are Beijing and Shanghai. After all, these two places are the best in the country in terms of education, medical care or other aspects. Many people are trying their best to register their household registration in these two places.

"Dacheng, do you have anything else to add?" Jin Zhihai's eyes were full of anticipation.

He came here today, firstly to ask his childhood friend to spare some time to help them with the interrogation, and secondly to talk about the case and see if he could get some inspiration.

Although Li Yancheng has worked in the Social Affairs Bureau for many years, he has never been very good at solving cases. The main reason is that he has spent too little time working on the front line.

But because he has lived for decades longer than others, the suggestions he puts forward often always make the investigators' eyes light up.

Jin Zhihai came here today just to find that feeling of being enlightened.

"If you want me to give some advice on the case, you have to let me see something. I just talked about it. I didn't even see the crime scene. What opinions can I have?"

Li Yancheng spread his hands and said helplessly.

By the time he intervened in the trial of a case from ten years ago, a long time had passed since the last case occurred. The scene had long been destroyed beyond recognition. All he could see were some photos of the scene and files.

For some reason, he still likes to go there in person, even though he may not see anything.

Of course, I definitely won’t be there tonight.

Before he finished speaking, Jin Zhihai took out a stack of photos and a notebook from the bag he brought with him.

"I know you want to see the scene. If I have nothing to do tomorrow, I'll take you there. Now take a look at the photos and records of the case."

Li Yancheng is not only an interrogation expert at the Social Affairs Bureau headquarters, but also in the public security system. Even if the case has not yet reached the point where he needs to intervene, and his superiors have not approved it, it is not particularly against the rules to take a look at it in advance.

So he didn't act pretentiously. He took the stack of photos from Jin Zhihai and looked at them carefully.

Looking at the girl in the photo, who was only in her early twenties and had just entered her best years, closing her eyes like that, his face turned extremely ugly.

After taking two deep breaths to suppress the anger that was about to burst out in his heart, Li Yancheng carefully looked at the photos in his hand, one after another, under the light in the yard.

"Were these two footprints left by the same person?" After looking through the twenty or so photos in his hand, Li Yancheng took out two and placed them side by side on the stone table.

There are two footprints in these two photos. One is relatively complete and worth identifying and comparing. The other one only has half a footprint, which is on the forefoot. There is no footprint on the heel. This is because there happened to be a stone behind the owner of the foot when he stepped on it, and the heel landed on the stone.

The reason why he believed that these half footprints belonged to the same person was because the sole marks left on the forefoot were very similar.

"Yes, this complete footprint is what I just told you about. It also appeared at the scene of the case ten years ago. We specially asked the footprint expert in the department to confirm it. Although the pattern of the sole is different, it can be confirmed that the footprint left at this scene and the footprint ten years ago were left by the same person.

Experts said that based on the footprints, the criminal is estimated to be between 1.7 and 1.75 meters tall, thin, weighing about 110 kilograms, and is a male.

“Can we tell how big the criminal’s hands are based on the pinch marks on the victim’s neck?”

After listening to what Jin Zhihai said, Li Yancheng took out another photo and put it on the table.

This photo is a close-up of the deceased's neck, and the strangulation marks on the neck can be clearly seen.

"It is the size of a normal man's hand, nothing special, but... the criminal strangled the victim with his left hand."

As he spoke, Jin Zhihai gestured with his hand.

"But this does not mean that the left hand was the criminal's dominant hand. Maybe his right hand was busy fixing the victim's arm or leg."

Hearing that the criminal used his left hand to strangle the victim, Li Yancheng was silent for a while and said.

Just after saying this, he realized something was wrong. He first raised his left hand and gestured slightly to his neck, then took out a photo and looked at it, then waved his hand.

"No, no, I take that back. This criminal is most likely left-handed. In other words, this person is probably left-handed."

"Tell me why you think so."

Jin Zhihai did not refute, but asked Li Yancheng with interest to explain the reasons for his judgment.

It can be seen that they should have also concluded that the criminal was left-handed.

"I just said that the man used his right hand to fix the victim's arms or legs. This is wrong. The victim's arms were tied behind his back with ropes and pressed under his body. There was no need to fix them. The same goes for his legs."

From the photos, we can see that when the deceased died, both of his arms were pressed under his body, with ropes tied at his wrists. The same was true for his legs, with ropes tied at his ankles.

"That is to say, when the criminal committed the crime, his right hand was free, and he used his left hand to strangle the victim, so he is most likely left-handed, but..."

At this point, Li Yancheng picked up a photo of the deceased's ankles tied with a rope.

"But what?"

"What I want to say is that this person tied up the victim's feet. After tying them up, he could only lift the victim's legs like this to commit the crime, in this position...

Zhihai, is there any criminal's bodily fluid in the body of the deceased?"

"Have"

"If he is the same person from ten years ago, why did he never tie up his victims before and start tying them up again now? Why would he change his crime habits?"

Indeed, in a series of cases from ten years ago, several known victims said their hands and feet were not tied.

“Could it be that he is getting old and is worried that he is not up to the task?”

The investigators also discussed this issue, but ultimately did not come up with any answer. After all, only after catching the man could they find out from him why he chose such a difficult action.

"Are you unable to do it?" Li Yancheng frowned. He felt that these four words were a bit too light.

It is not an easy task to strangle an adult to death with bare hands. At the very least, one has to do it continuously for more than two minutes without slacking off, and it also requires a lot of force.

One hand, with so much strength, is it not enough? I'm afraid it's not that simple.

Shaking his head, keeping the question in mind, he asked the next question.

"Didn't you find the first crime scene?"

"Not yet. The victim was a waitress at a restaurant. She usually walked to and from get off work. After she left work at 9 o'clock that night and said goodbye to her colleagues, no one saw her since. It takes 20 minutes to walk from the restaurant to her home. There are two roads in total.

One of the roads is a small road, and the distance between the two roads is about the same. We believe that the victim must have taken this small road that night. "

“Why do you make this judgment?”

"That's one of the reasons why we want to combine this case with a series of cases from ten years ago. There was a street light on that path. According to the investigation, at nine o'clock, when someone walked along that path before the victim walked along this path, the street light was still on.

But when we visited later, we found that the street light had been damaged. Residents nearby said that it was broken that night and the method was very similar to that used ten years ago. Unfortunately, we did not find any suspicious traces on that path.

Judging from the damaged street lamp, the first crime scene should be on that path. After the victim walked onto that path, he was knocked unconscious from behind by the criminals and then taken away from the scene.

That person should have used a bicycle or other silent means of transportation to take the victim to the second crime scene, which was a little over a kilometer away.”

In the case ten years ago, the perpetrator also broke a street lamp, knocked the victim unconscious in the dark and took him away from the scene. From this point of view, they are really similar.

"Didn't you notice anything unusual on that trail?"

"Indeed, no, because by the time the comrades from the Criminal Investigation Division of the Dianhai Branch arrived, the road had already been cleaned by sanitation workers."

No wonder!
Li Yancheng raised his eyebrows.

The criminal will definitely leave traces at the first scene, but if they have been cleaned up, there is nothing we can do.

"Zhi Hai, you just said that the victim had two routes to choose from when going home from get off work. What was the other route like? Which route did the victim usually take to go home from get off work?"

"Not sure which way to go, the other way is the big way."

Jin Zhihai opened the notebook and pointed to one of the sketches and said, "Dacheng, look, this is the main road, and this is the small road..."

"Wait a moment..."

Before he could finish his words, Li Yancheng interrupted him.

"Since there were no suspicious traces found on the path, why did you conclude that the victim was knocked unconscious on the path? Was it just based on the broken street lamp?"

"Uh……"

Jin Zhihai was stunned by the question.
