After clarifying the goal, the rest of the matter was much simpler, Cao Le worked closely with the remaining two team members, and soon took pictures and preserved all the traces in the hall.

Walking inside along the highly targeted tracks, the traces on the ground still did not change.

It is conceivable that even if Crime Member 2 has already passed through the area of the hall where traces are most likely to be found, his next actions are still cautious.

This kind of behavior from the beginning to the end is enough to show the caution and elite of the criminal group.

The side room is lined with clutter by the window, and it is unknown if it was deliberately placed by Crime Member 2 or if they were just that.

The Fifth Zheng took a few glances on the side, but did not find any obvious traces of human movement, and it seemed that this pile of debris had been in this old abandoned house since I didn't know when.

But the fifth is keenly aware of some anomalies through the dense nail marks next to the debris.

If this window is not convenient for installing surveillance equipment, criminal member No. 2 can just leave here, and there is no need to waste time in circles and circles.

Even if Crime Member 2 was trying to figure out how to set up the monitoring installation location, there was no need for him to walk back and forth blindly.

Measured by a well-trained bandit, whether or not surveillance can be installed here can be judged at a glance, and it will definitely not be so indecisive as to need to pace back and forth to consider.

This redundant action of pacing back and forth is obviously used to carry other behavioral motives.

To rationalize it a little, the best way to complete such a debris accumulation without leaving any traces is to keep the debris of the base unmoving, and recombine some of the scattered debris together, so that you can reconstruct the shielding range of this debris pile.

As long as the dust surface of part of the area does not change, even if there is a change in the remaining places, it can be avoided by overlapping places.

Such ingenuity, it is inevitable to fall a certain flaw, at this time the advantage of the debris pile against the wall will be revealed, as long as the biggest flaw relies on the blind spot of the wall to block, then if the person who came to check just a few glances in a hurry, it is impossible to find the violation of this debris pile.

This pile of debris only needs to be able to successfully perfunctory the outside world for a while, and when the dust on it is covered again, all traces of movement will be lost in the dust world.

After letting the people on the side record the overall layout of the place, the fifth hurriedly picked up the sundries on the top layer, looked at them carefully, and indeed found some very fresh dust indentations.

The clutter here is indeed done through post-processing!

"Preserve all the details here, and restore the traces left by the monitoring equipment."

After the fifth Zheng gave an order, he stood aside as a guide and asked Cao Le and the three of them to clean up this large piece of debris.

"There was no trace of finger pressing or contact at all, how the hell did he manage to move the clutter? Could it be that he also designed special mobile equipment? ”

Cao Le looked around the pile of debris, and found no traces of finger pressing at all, except for some hidden traces of treatment, which made this scene reveal a strange atmosphere everywhere.

If you open your mind a little, you will be filled with strange things like mind transfer and teleportation.

Out of a rigorous attitude, Cao Le believes that this is a dumb puzzle set up by criminal member No. 2, and uses some less common methods to carry these miscellaneous items.

"If you look closely, you'll always find any clues that remain."

Fifth, he has always adhered to a guiding attitude on the side, although he has seen some clues, but he has not given direct hints.

There was a feeling of being deliberately tested, which instantly doubled Cao Le's pressure. At the previous level at the entrance of the hall, the fifth was the first to discover the fine and dense nail marks on the ground, and if he was tested again, it would be a shame.

There is no presence at all.

But after pondering for a long time, Cao Le still didn't find any clues.

If Crime Member 2 is using an iron hook to move these objects, it will inevitably leave some deep or shallow cone marks on the surface of the objects;

If Offender 2 is using a rope to move these items, the strangulation marks will be quite obvious, even if Offender 2 is hanging with a rope in the joint gap of the debris, it will also leave some friction marks.

In the process of moving, the traces left by these two props are the smallest, and if there are any other possibilities, Cao Le can't think about it for a while.

Holding his head and continuing to stiffen for a while, he still didn't have any clue, so he could only ask with an embarrassed smile: "Fifth, there are no traces of iron hooks and cone thorns on this batch of sundries, and there are no traces of thin lines hanging, so what other methods can be used to move?" ”

Time was pressing, and the fifth positive didn't want to waste too much time, so he pointed out: "The two ways you want to move have a certain degree of feasibility, if it doesn't work, it means that the idea of criminal member No. 2 to hide traces is no longer hidden through a small contact area."

It's easy to overlook the small traces of the past, but if they are eventually discovered, then continuing to do the same thing in the debris pile is just repeating the mistakes of the past.

Under such a sophisticated premise, with the rigor of a criminal group, Criminal Member No. 2 will definitely change the way of hiding traces.

For small marks such as acupressure, it is much easier to disguise than footprints, and it is likely that Criminal Member 2 used this tactic on this debris pile. ”

Fifth, as soon as these words came out, Cao Le's eyes also lit up, and he hurriedly shook his head to see where there were traces that were covered.

"There's no trace of this, right?"

After a few glances, Cao Le was a little skeptical that there was something wrong with the Fifth Positive reasoning. Or maybe he's just blind and can't see the key details.

"Even if the items in the room are dusted, they will always be the one facing up the most.

The dust marks on this side are in a room, and they generally have a high degree of uniformity, and it is also the side that Crime Member 2 is unlikely to touch.

As for the degree of dust accumulation on the other sides, it will be related to the ability of the material to absorb ash and the position of the material.

Although the degree of dust accumulation is almost fixed, because it is impossible for people to care about these details, and it is impossible to have an empirical prediction in this regard, the different aspects of these dust accumulation degrees are where the criminal member No. 2 does his work.

If you look closely at the various sides of these debris, you will find that some wooden debris has completely different dust accumulation on the same surface.

Although there is not much difference in such shades, this is also one of the ironclad proofs of passivity.

It is even certain that Criminal Member 2 not only refined these passive traces, but even prepared a packet of dust powder to refine those passive traces. ”

When Cao Le heard the explanation of the Fifth Positive, he finally had a feeling of enlightenment, this kind of meticulous observation ability was indeed not comparable to him.

After learning this kind of action, the rest of the work is much simpler, the debris was moved away layer by layer, and a new trace of being suppressed by the debris appeared in front of everyone.

This is a card slot for mounting a pinhole camera, so that the camera's lens can see through a natural hole at the bottom of the plastic window paper.

In this way, as long as the pinhole camera is deviated from this hole, then by the principle of backlighting in the dark light in the room, then people outside will not be able to find the dark camera without looking carefully.

In addition, due to the interference of the holes, the mirror reflection of the camera is also difficult to be seen by people outside unless it is at a certain angle.

After recording so many precision designs, Cao Le was also full of sighs, and after chatting casually with his team members, he was suddenly stunned again, as if he had thought of a very major loophole.

"Fifth, it's a little wrong. Even before the explosion, you had already asked me to come to this demolition area to find someone.

With time running out, how did Crime Member 2 have enough time to pile up this clutter after recovering the monitoring equipment?

What's more, I met that suspicious figure at the beginning, but in the alleyway of the demolition area, in just a few minutes, can Criminal Member No. 2 complete so many complex operations? ”

Cao Le's question also made his two team members stunned for a moment, if this kind of BUG really exists, then it only shows one thing - the disguise here is just a suspicious grave.

The real hidden location of the surveillance cameras, they simply did not find out!

"Holy, it's not all misleading. The real surveillance installation site is not here at all!

Even thinking a little deeper, at the beginning, the time was urgent, and after the criminal organization found out that there were police chasing after him, the criminal member No. 2 who was hiding here left directly.

Before leaving, he deliberately induced us to think that the surveillance was installed in the alley where Zhang Yun had passed.

If that's the case, as long as we can find the monitoring equipment, we may be able to locate another hidden nest in their organization through the records inside.

When the time comes, we will have more clues, and maybe we will be able to draw up a list of suspects. ”

Suddenly, Cao Le, who seemed to have opened his mind, was full of joy and imagined many happy endings, which caused the fifth to frown.

This Cao Le, how can he waste all his ingenuity on some inconsequential details?!
