Chapter 948

In the office building of the Changyang Municipal Criminal Investigation Detachment, the lights did not go out all night.

Although Jiang Yuan did not urge, the criminal investigators of the detachment had this consciousness. They have already invited Jiang Yuan, and if they don't work hard, it will be the detachment's turn to be sold next.

The next morning, Yu Wenshu also came very early.

Just sitting in the office, picking up the cup and taking a sip of tea, several captains knocked on the door and came in.

Yu Wenshu nodded with satisfaction. Although the special task force is responsible to Jiang Yuan, Yu Wenshu still needs to control the overall situation. His relationship with Jiang Yuan is like a producer and a director. The producer who pays for the game and integrates resources is the producer, but when it comes to specific business links, when it comes to using these resources, the director is the most important.

"How is the situation? Looking at your expressions, they are all good?" Yu Wenshu got up and sat on the sofa for meeting.

Several captains sat down separately.

The captain of the map investigation brigade couldn't wait to say: "We really have discoveries!"

"Oh? Tell me about it." Yu Wenshu came to the spirit all of a sudden.

Why is map investigation becoming more and more valued, because map investigation can really solve cases.

The images produced by map investigation can often clarify the facts of the case. Compared with the suspect who swears, the dense interrogation records, a case, if you can find monitoring video or any other image evidence, it is not far from solving the case.

Foreign countries may have lawyers talking about privacy, fruit of the poisonous tree, excluding evidence, etc. Domestic does not come to this set.

Domestic courts rarely exclude evidence, and because the judge decides the case and the prosecutor decides to prosecute, so even if it is evidence that needs to be excluded, it is also seen by the judge and prosecutor before being excluded.

In this way, as long as there is information in the image that can prove the facts of the case, even if the judge excludes the evidence in court, the tendency of the case is obvious.

"According to the time of death modified by Team Leader Jiang, we measured the vehicles passing through the corpse disposal point. At present, there are four vehicles, and the time passing through the corpse disposal point significantly exceeds the normal time limit. We have already started to investigate." The captain of the map investigation brigade smiled and introduced this idea about the time limit.

It sounds simple, it is nothing more than determining a normal time at two points before and after the corpse disposal point, and then looking at the vehicles passing through these two points, whether there is a significant overtime situation.

Because the corpse disposal point itself has no monitoring video, but corpse disposal requires time. Even in the case of cooperation between two people, getting off the car and walking to the river, going up and down the river embankment, and carrying the watermelon-sized corpse pieces a few times, it takes at least a quarter of an hour to delay. If it is slower, it takes at least twenty minutes for one person.

This gave the map investigation brigade a starting point for investigation.

However, it is not so easy to really operate, because it is not easy to find two suitable points. There are not many monitoring videos near the corpse disposal point, and even fewer can be seen clearly. In addition, there are forks in the middle, so in fact, it is no longer just a calculation of two points.

But in any case, the map investigation brigade finally determined a number of suspicious vehicles with this plan. Now, as long as they go to the door to investigate, ask them why they are driving overtime, and then look at the stains on the car, etc., it is possible to find the killer.

"Well done!" Yu Wenshu did not spare the praise, praised several times, smoothed the mentality of the captain of the map investigation brigade who stayed up all night, and then turned to look at others.

"We also have discoveries here." Wan Baoming hurriedly said: "After we traced the fibers on the deceased, we found three woven bags, one of which has a concentrated sales volume in our Changyang City. In addition, this woven bag is a coated product, and most of the coatings of the woven bags we found are complete, so there is reason to believe that these woven bags are used for the first time, at most the second time."

"Can you track the user?" Yu Wenshu was a bit surprised. Woven bags are really too popular. In contrast, if the killer used LV to pack the corpse, it would be better to investigate.

Wan Baoming said: "It is not possible to track the user directly, but we have now delineated a range. I feel that we can visit and cooperate to understand the situation of the missing person."

"Good." Yu Wenshu nodded. How to do it, it will be arranged by Jiang Yuan later. He is just understanding the progress in advance.

Immediately after, Ma Jiyang's criminal record group and Cao Chujun's kitchen knife group also explained the situation separately.

Yu Wenshu listened and nodded repeatedly. After listening, he was a bit surprised: "Your lines, it seems that they are all quite hopeful?"

"Yes, the current trend is quite good." Several people obviously realized this problem too.

"Multiple battle lines advancing together... Okay, it's quite good, worthy of being the special task force led by Jiang Yuan. Okay, Jiang Yuan's special task force, as long as it can be pushed forward, I support it."

Yu Wenshu said, and everyone breathed a sigh of relief.

Hearing the sound, Ma Jiyang smiled and said: "Before, I was worried about no clues. This time, the clues are all advancing, but I am a bit at a loss."

Ordinary special task forces solve cases. No matter how many ideas or clues are put forward, in the end, only one battle line can break through at the moment of solving the case.

Most special task forces are doing one line of clues, and then find that they can't follow up, so they have to stop, and then in the case of no new clues, brainstorm, study a new clue, and continue to investigate. It belongs to people waiting for clues, not clues waiting for people.

In the end, the key to whether a special task force can continue is whether there are clues. As long as there are clues, according to the current system, the homicide special task force will continue to operate, even if the pursuit is very difficult, it will persist in the pursuit. Unless it involves politics.

However, too many clues are another burden. Investigating every line of clues, the cost is to rise with a roll.

In ordinary homicide cases, abandoning some clues and specializing in the most hopeful clues is also very common. This is also what Ma Captain and others are more worried about.

If they want to cut, their kind of visiting classes are definitely prioritized for reduction.

Yu Wenshu did not make such a decision, one is because he did not want to interfere with Jiang Yuan's judgment, and the other is because this case is a dismemberment case.

Normal dismemberment cases are inclined to the no-clue style. Too many clues are rare, which is rare. Moreover, it is still a distance from solving the case, and saving money cannot be used as a priority choice, at least not in this kind of case.

"Okay, all go to work, I am waiting for your good news." Yu Wenshu got up and sent several captains out.

Out of the door, several captains looked at each other, and their expressions became serious.

No matter how long the battle line is pulled, in the end, the breakthrough at the moment of solving the case can only be one battle line!
