Cheng Shi said nothing after hearing this, and Feng Tao continued: "There is no motive for the murder, there is no clear suspect, which is the biggest problem in this case so far!
Of course, the biggest problem is the case in the villa half a year ago, because it was a real secret room murder case!
Let’s all collectively discuss how the murderer committed the murder. After the discussion, we will adjourn the meeting and wait until the identities of the other two deceased people are found before we meet again!”
Cheng Shi naturally knew that it was difficult to solve the secret room murder. The room Luo Yunhua was in was locked, and even the windows were closed!
There is no trace of the presence of anyone else at the entire crime scene. It can be said that this secret room is a seamless secret room.
The only flaw was the murder weapon. If the murder weapon had been left at the scene, this case would have ended as a suicide!
Thinking of this, an idea flashed in Cheng Shi's mind!
Yes, why not leave the murder weapon? In this case, the case should end as a suicide!
If the murderer didn't leave the murder weapon, maybe he couldn't leave it behind!
The locked room murder case is the most famous of all homicide cases with obvious characteristics.
Because such a case needs to be completed in a closed space, but the murderer did not appear in the secret room!
Throughout the ages, there have been many secret room murder cases that were either successfully solved in the end or forgotten by people but have not yet been solved!
How the murderer killed has become the most critical issue in this type of case, because if you don't understand how he killed, how can the case be established?
Cheng Shi did not express his opinion again. Although he had been to the scene, he did not know that it was a secret room at the time!
Therefore, his original reasoning was wrong, and reasoning cannot have wrong clues. Now he is not talking without correct clues.
The other clues were also recorded after Feng Tao's investigation. He was no longer sure if he had any misunderstandings.
Everyone in the conference room is talking about some speculations of their own, but the final result is that you speculate and he refutes.
Every clue that was speculated was ultimately refuted by others.
Feng Tao looked at the people discussing, rubbed his temples with a headache, and couldn't help but glance at Cheng Shi who was standing aside.
He already had some understanding of Cheng Shi's ability, and now he hoped that Cheng Shi could say something he didn't expect!
But Cheng Shi closed his eyes, slumped on the chair, and remained silent, as if he was not interested in this at all!
In the end, Feng Tao still said without speaking: "Please stop for a moment!"
After the police officers heard this, they stopped discussing and started to stare at Feng Tao. When Feng Tao saw everyone staring at him, he continued.
"Everyone is having such a lively discussion, why don't you express your opinion, Agent Cheng? Just now you said that the method of killing people in the abandoned factory is so exciting!"
Only then did Cheng Shi open his eyes, and Feng Tao actually asked himself, what would happen if he didn't speak anymore!
After all, Feng Tao is now the leader here!
But Cheng Shi really didn't have much idea about this now. He looked at the time and then at Feng Tao.
He had no choice but to say: "I just learned about this case today, I don't know much about it, and it's getting late!
It’s time for us to get off work and recharge ourselves so that we can have the strength to investigate the case tomorrow. We’ll talk about this at the next meeting!”
Feng Tao stared at Cheng Shi for a while, and when he saw that it was indeed getting late, he said, "Let's disband. We must find out the identities of the two deceased people tomorrow!"
Cheng Shi winked at Deng Xin, and after Feng Tao announced the end of the meeting, Cheng Shi left the conference room.
Deng Xin followed closely and said as they walked: "Brother Cheng, why didn't you tell me just now? Haven't you been to the scene?!"
Cheng Shi showed a helpless expression and said, "I've been to the scene and I can see it?!"
"Then you didn't know it after walking around the abandoned factory!" Deng Xin scratched his head and replied.
Cheng Shi ignored him and asked: "Based on your years of catching thieves, did you find anything at the scene? What clues did the other party leave behind?!"
After hearing this, Deng Xin became serious and said in a deep voice: "There are many traces at the door of the abandoned factory, and I found a relatively deep footprint at the door!
It must be the murderer's footprints. He swung directly to the door. When he landed, he would naturally leave a relatively deep footprint!
But I followed a few footprints, and they all ended up on the grass on the path, so I basically found nothing there!"
Cheng Shi turned his head and looked at Deng Xin, smiled and said: "Basically! That means we have discovered something!"
Deng Xin smiled and said: "Indeed, I already know a lot of information about the murderer in the warehouse!
This person is about 30 years old, about 175cm tall, and weighs about 70kg!
Hehe, Brother Cheng, do you want to know how I know this information?!"
Cheng Shi was stunned after hearing this. He already understood how Deng Xin knew it. Then he smiled and said, "You knew it based on the other party's footprints, right?"
Deng Xin was stunned after hearing this, smiled awkwardly, scratched his head and said, "As expected of Brother Cheng, I can't hide anything from you. It seems that I'm just doing my own thing!"
Cheng Shi shook his head and continued: "I don't understand this, I just know, based on the depth of the perpetrator's footprints!
Finally, the weight and height of the criminal can be estimated. Knowing the height and weight, we can also estimate the weight and weight of the criminal.
Based on a series of footprints and footprints, the age of the criminal can be roughly determined!
Children's steps are very short, and their footprints are very thin. The distance between the footprints is often irregular, and the walking route is often curved.
Young people tend to have large footprints, long strides, even distance between footprints, and walk in a straight line.
Middle-aged people walk steadily and slowly, and the distance between footprints becomes shorter.
The stride length of older people becomes shorter, and the pressure in the heel of the foot is heavier than that of the ball of the foot.
The pace was chaotic and the distance between the footprints was uneven, indicating that the criminal might be exhausted or injured.
The indentations on the heels of the footprints are deep and the forefoot is shallow, indicating that the walker held his chest up, his abdomen in, and his body relatively straight.
By carefully studying the criminal's footprints, you can also determine the time when the crime was committed! For example, it rained at midnight.
There are many pockmarks on the footprints, which means they were left before the rain. The pockmarks are few and shallow, which means they were left when the rain was about to stop.
The footprints are smooth and have no pits, which are undoubtedly left after the rain!
On summer and autumn nights, the footprints left in the first half of the night often have traces of insects crawling over them.
For footprints left in the second half of the night, because the ground is relatively damp and the soil is easily broken, the edges of the footprints are often unclear.
So when you used to catch thieves, you mostly tracked them based on their footprints, right?!"
After Deng Xin heard this, she said with a surprised look on her face: "Brother Cheng, why don't you stop joking? You still don't understand?! Then what I know means nothing!"
Cheng Shi smiled and shook his head, then comforted Deng Xin and said, "I only know some normal theories. I can't judge the other person's height and weight!"
Deng Xin sighed and said, "Now I can roughly guess a lot about people just by looking at their shoe prints. I thought I was the only one with this ability, but it turns out I was overthinking it!"
Cheng Shi continued: "This ability is developed slowly because you often track thieves! Didn't you feel this way before?!"
Deng Xin nodded and said decadently: "Yes, I only felt this way in the past year or so. I thought it was my innate ability!"
Cheng Shi suddenly thought of a person and had an idea in his mind, and then said: "This is a real skill. Let me tell you a story!"
Deng Xin then raised her head in confusion and said, "What story!"
Cheng Shi thought about the story in his mind and said, "There was a man named Ma Yulin in Chifeng. His family was poor when he was young. When he was a teenager, he herded sheep for the rich man's family.
He practiced tracking skills when he was herding sheep. He based on the size, fatness, coat color, characteristics and other physical characteristics of the sheep.
After a long period of observation and comparison, I developed the ability to associate the physical characteristics of sheep by looking at hoof prints.
Therefore, he seldom counts the sheep while tending them. As long as he follows the sheep and looks at the hoof prints, he will know whether they are missing or which one is missing!
As long as he follows the hoofprints, he will be able to find them no matter how far or near they are. From then on, in addition to finding his own lost sheep, he often helped other people find their lost livestock.
Because he is unusually sensitive to traces, he can not only track cattle, horses, and sheep, but is also extremely interested in human footprints!
After that, by identifying the person's footprints, he can determine the person's gender, height, weight, age, and body shape.
Then one day decades later, a store in the county was robbed. The police found two types of suspicious footprints at the scene, and then traced them outside the door.
Someone recommended Ma Yulin to the catcher, so the catcher invited him to the scene, and saw Ma Yulin measuring two footprints!
Finally, after looking over and over again and pondering over it, I started tracking it as soon as it was dawn, and chased it all the way to the door of a house in another village!
The police officer entered the courtyard and found two men. After taking them back to the county government office, the thief quickly explained how he committed the crime and finally found the dirt.
Therefore, at the age of several decades, Ma Yulin was absorbed into the county government and became a police agent. His amazing intuition and his long-term practice.
He already has a complete set of tracking experience in his mind, from the weight of the footprints, gait, stride, virtual edge, pressure, soil and other conditions!
He can know a person's gender, occupation, body shape, habits, age, and physical characteristics!
