As for Zeng Yayan and the others, they originally thought that the fifth had turned off the footprint light because he saw something, but they didn't expect his reason for turning off the light to be like this, which made them a little puzzled.

"If you don't adopt the footprints, then only fingerprint clues remain. But the habitual thief was obviously stealing with gloves, can his fingerprints be found in this corridor? ”

While putting away the footprint lamp, Xie Shuangcheng took the lead in asking. This sentence was also a question in the minds of others, and for a while, the fifth was once again the focus of everyone.

If the habitual thief had come to steal for the first time, he might have taken off his gloves outside the residential building, but the long-term success of the theft had already inflated his self-confidence.

From the previous footprints, it can be seen that there were several traces of shoe cover trampling in the track of the residents' footprints, and after turning a corner, the shoe cover crushing marks disappeared.

The traces left behind indicate that this section of the corridor has become a psychological safety zone in the mind of the habitual thief, and the shoe covers and gloves used to cover his footprints and fingerprints will be removed in this corridor.

Since gloves are not disposable items, habitual thieves will inevitably put them back in their pockets after taking them off. According to the behavior and habits of ordinary people, in order to prevent gloves from getting dirty when taking off shoe covers, it is likely that the gloves have been removed when the habitual thief takes off the shoe covers.

In other words, the habitual thief was already taking off his gloves the moment he left the scene of the theft.

He walked down while taking off his gloves, and when he came to the corner of the first staircase, he took off the very conspicuous thing of his shoe covers.

When the habitual thief left the scene of the theft, he used his backpack to store a bottle of wine and a large piece of pork, according to the consistent habits of social people, he must not be a backpack, it must be a backpack.

When there is a weight on one shoulder and you need to carefully remove the shoe cover, people will subconsciously reach out to hold the support next to them.

It is based on this inference that the probability of leaving habitual thief fingerprints on the corner of the staircase is the highest.

Of course. Since the backpack is used to sneaking in, it is very likely that he will put down the backpack first and then bend down to take off the shoe cover if he does not cherish it.

As for which one it is, let's check some nearby fingerprints first. ”

Such a simple reasoning had already been thought about by the Fifth Zheng when he had just carefully observed the footprint lamp, and now that it was time to collect fingerprints, he told it to him.

Originally, I just wanted to confirm the possibility of collecting fingerprints, but I didn't expect that the fifth official directly gave the most suspicious fingerprint storage place, and Xie Shuangcheng, who was a little surprised, hurriedly took out the fingerprint dominant medicine and began to collect the fingerprints around.

The fingerprints stored on the surrounding walls, debris, and railings were all developed and photographed, and then sent to the technical department of the city bureau for comparison.

"Officer, are you going to catch that habitual thief right away?"

Seeing that the fifth Zheng had just walked to the corner of the first staircase and said so many ways, and the fingerprints collected had also been sent for inspection, Du Hai, who was simply overjoyed, hurriedly came over and asked enthusiastically.

"Although there is the greatest possibility of fingerprints left here, no one knows whether the fingerprints left behind are complete, and further exploration is needed to further explore several places where fingerprints may appear.

In addition, the shoe covers taken off by habitual thieves may also be thrown into various debris in the corridor, and finding out the shoe covers is more conducive to convicting habitual thieves. ”

The fifth Zheng's answer was not only to perfunctory Du Hai, but also to remind everyone to continue to keep up.

Having already scanned the nearby pile of debris, and found no discarded shoe covers, the fifth official began to search downstairs.

"Seeing that you are looking so carefully, is there a high probability that habitual thieves have lost shoe covers nearby?"

Zeng Yayan was a little curious when she was looking around for something just now, but because she was also helping to take pictures, she didn't ask for the first time.

"If the habitual thief swells to a certain extent, he will normally leave his shoe cover nearby.

However, judging by the habitual thief's usual cautious style, he should have taken the shoe covers to a more dangerous area before discarding them.

In other words, if a pedestrian suddenly appears in the hallway, he will hide his shoe cover in the clutter at the chance encounter, or after leaving the residential building, he will throw it in the nearby garbage can. ”

For the fifth positive, who is habitually stealing and losing shoe covers, he may already know it, and he was originally going to let people go separately to collect evidence. One team searched in the hallway, and the other team searched the garbage heap downstairs.

Unfortunately, if you want to use shoe covers as evidence, you must have two police officers who are qualified to collect evidence. This matter is not worth calling the two of them over, so they can only continue to search and collect evidence step by step.

"Do you need us to find this neighborhood together?"

Listening to the fifth positive analysis, Li Wenxing also wanted to help speed up the search process.

"No need.

The discarding of shoe covers is not a hidden treasure, it is only necessary to keep it from being discovered by pedestrians with a normal perspective.

Such hiding places are either visual blind spots, or the debris itself has an infrequently used confined space.

After these two screenings, the workload of these piles of debris piled up in the corridor is actually not large.

The main job of Captain Li and your assistant is to collect and upload fingerprints from suspicious points, and pay attention to the comparison and feedback results of fingerprints at any time.

For those habitual offenders who have been fed back, I think Captain Li should be very familiar with them. ”

Looking for something is not the more people the better, the so-called many people are mixed, in the case of uneven search ability, the more people participate, in fact, the greater the possibility of omission.

In the case that the workload is not huge, the fifth is that it is better to find it by himself.

For this rejection of the fifth positive, Li Wenxing felt a faint ability to control the overall situation.

This kind of control ability is not the kind of arbitrariness that makes great achievements, but a kind of well-distributed strategy, and everyone performs their own duties, which is the best way to give full play to the overall effect.

Such a character is a proper cadre candidate, not the kind of prickly genius who only has one skill but is slightly out of place.

After recognizing more of the merits of the Fifth Positive, he seemed to see a sense of immeasurable promise in the Fifth Positive.

Perhaps, in ten or twenty years, their provincial hall will be able to have a detective from the Megatron Domain!

As soon as he thought of this, Li Wenxing's displeasure with the Fifth Positive some time ago all disappeared, and he began to appreciate the young man in front of him.

The group looked for a few minutes in the corridor slowly, and the first relatively cramped intersection appeared downstairs.

"Fifth, where do you need to collect fingerprints here?"

Xie Shuangcheng, who had nothing to do for a few minutes, asked again.

"Didn't you collect them all like last time?"

Du Tao, the male owner who had experienced the police handling the case behind him, was also very excited at this time, and couldn't help but interject.

No matter what nonsense he had to say behind him, he was immediately suffocated by Xie Shuangcheng's eyes.

"No, I don't. Just take the fingerprint on one side of the railing. Crossing a narrow area facing a pile of debris can obstruct one's vision, and this kind of voluntary loss of control and security will not happen to a habitual thief.

On the premise of passing sideways through a narrow area and needing to carry more than ten pounds of weight with one hand, the other hand will inevitably use the help of the railing to relieve the psychological pressure when facing high altitude, so as to obtain a stronger sense of control of the body. ”

In order to facilitate Xie Shuangcheng's fingerprint collection, the fifth Zheng told his reasoning.

After Xie Shuangcheng heard this, he sprayed the developing reagent on the railing. It's just that because there are too many people passing sideways, and some people are even more violent, the extraction of fingerprints is not ideal, and there are many fingerprints with traces of drag and distortion, and there is not much reference significance at all.

Seeing this situation, the fifth is also a little worried, if the fingerprint extraction fails at this place, then the possibility of fingerprints extracted in the next narrow place is even lower.

Continuing to search to the last narrow intersection, the Fifth Zheng only took a slight look and found that there was no longer any forensic value here.

"There is a fiber residue in the corner gap of the railing, which is obviously someone holding a ball of clothing or cloth passing through here, and after the cloth wipes, the fingerprints on it no longer have extraction value."

After a brief explanation, the fifth man led everyone to continue downstairs.

Now that it has been gradually investigated to the second floor, there is no other harvest except for the extraction of two collective fingerprints, if you can't find the key evidence of shoe covers in the next process, then all the exploration work may be frustrated.

"Fifth, what if the habitual thief collects the shoe covers and throws them away when he leaves the community?"

The collected fingerprints have been sent back for a period of time, and now there is still no feedback from the technical department, and the squadron leader Li Wenxing is also a little apprehensive about the evidence collection process.

"According to the instinct of ordinary people, it is impossible to put a pair of shoe covers that have been stepped on by the soles of their shoes on themselves.

The habitual thief who has succeeded repeatedly, in the case of inflated self-confidence, this ordinary person's hygiene habits will also return to his behavior habits indefinitely.

Judging from the current search, he did not discard the shoe covers in his hands in the debris pile, which shows that although he has regarded the corridor as a psychological safety zone, there is a pair of used shoe covers in the clutter pile of the old house, which is still very unreasonable in his safety determination.

In order to rationalize a pair of used shoe covers, and to avoid the irrationality of pedestrians holding shoe covers, he will inevitably throw the shoe covers in the garbage heap near the residential building the moment he leaves the residential building. ”

Although the shoe cover has not been found, the fifth is becoming more and more confident about the discarding place of the shoe cover.
