According to Lockard's Law of Material Exchange, every action would leave a trace.
There was no such thing as a " traceless " crime scene. As long as a crime had been committed, there would definitely be traces left behind.
Even if there were no witnesses at the scene of the incident, could the suspect really be so thorough that he did not leave any clues behind?
Of course, for the police station, it was difficult to completely control it from a technical level.
The pen in his hand knocked on the table unconsciously, making a 'da da' sound, Ye Feng fell into deep thought.
He slammed the table. He had thought of something!
Often, such break-ins were not accidental.
It was impossible for the suspect to randomly pick a target. Instead, he would investigate in advance and find out the situation.
Otherwise, if you act rashly and sneak in in the middle of the night, you will find that several people are there and the house is full of people.
Theft was usually done by a gang. Some people were responsible for investigating the situation, while others were responsible for breaking into the house.
And the communication between the gangs was very likely through secret codes!
After figuring out the situation, he painted a secret code on the wall at the door of the house to inform others.
Previously, there had been cases of break-ins that had been solved, and they had publicized something similar to a secret code.
For example," -" meant that there was someone in the day and no one at night; If the symbols were reversed, the meaning would be the opposite.
For example,"..." It means that there are three family members;
For example,"
wait
After this set of secret codes was announced, many residents in various places were shocked to find that there were secret codes at their own doors. They were probably targeted by others before!
Of course, this code was no longer used by thieves.
It was nothing more than a matter of changing a set of secret codes. Perhaps there were similar secret codes at the doors of these few households!
If he could decipher the meaning of the code, then he would have a clear target to capture the suspect!
"Brother Zhang, did you notice that there were no special marks on the doors of the few houses that were robbed?”
Ye Feng raised his head and asked Zhang Xu.
Zhang Xu nodded and shook his head.
"We noticed this, but none of the houses that were robbed had these special marks on their doors. We searched carefully.”
Ye Feng could not help but frown.
Thinking about it, he was an old policeman. He would definitely be able to think of this.
But he did not discover anything, this made Ye Feng scratch his head.
Thinking about it, Ye Feng decided to go to the field to take a look.
"Zhou Suo, I'll go to the scene to take a look. Perhaps I'll find something!”Ye Feng asked Zhou Yi Cheng.
Zhou Yi nodded." You and Old Chen can go. It's good to go out and take a look!”
Although Zhou Yi Cheng did not have much hope, Ye Feng was still a newbie, it would be beneficial for him to go to the scene and learn more.
Moreover, old policemen like them were prone to falling into misunderstandings. Newbies had a lively mind and might discover something!
Thus, Chen Chang brought Ye Feng out and headed straight to a few old districts.
On the way, Chen Chang started talking again.
"These old residential areas don't have any property management or surveillance coverage. If something happens, we'll have to run around!”
"Feng, you just came here and don't know. The community has tried several times to get the residents to hire a specialized property management company, but everyone is unwilling to pay!”
"Even if we install surveillance cameras, will we be able to find more clues to solve the case?”
"Anyway, I can't say anything!"
"Moreover, the old folks in these old districts are the hardest to deal with.”
"You have to call the police for such a trivial matter. No matter how we deal with it, we are still not satisfied!”
"Anyway, I have a headache whenever I talk about these residential areas!”
"But don't say it. Although the old man and the old lady like to argue, a few young policemen in our station are willing to deal with them.”
"Do you know why?"
"Hey, those old ladies are always trying to introduce people to them. Do you think they won't be happy to go?”
"Haha!"
......
Chen Chang seemed to be doing a stand-up comedy, he did not need Ye Feng's response at all, as long as you did not stop him from opening his mouth!
Ye Feng's mouth twitched, his ears were buzzing.
Fortunately, they soon arrived at one of the old residential areas, Ye Feng was temporarily free.
Arriving at the first house that had been robbed, Ye Feng did not knock on the door rashly, he carefully observed the surroundings at the door.
The environment in the old neighborhood was naturally not very good. There were some junk piled up in the corridor, making it even messier.
It was a three-story building. It was neither high nor low. There was no security door installed, only an old iron door with small advertisements pasted on it.
Looking at the keyhole, Ye Feng could not help but frown, this was the oldest lock.
For thieves with a little skill, it was almost equivalent to not having any defenses.
As long as they were sure that no one was at home during a certain period of time, the thief would be able to steal a lot of money.
Ye Feng focused on the wall at the entrance, just like before, there were no special marks on it.
There were footprints near the ground, but Ye Feng felt that it was just a random kick from the resident, not a mark left by the thief.
He stood at the door and flipped through the case file for a while. He could not help but scratch his head.
It seemed like there really wasn't any direction to breakthrough!
