After the Guangming District Branch discovered that the on-site investigation detective found the photo, all his attention was focused on the photo, especially the investigation of the possible identity of the victim in the photo. Of course, it does not mean that this direction is not important, on the contrary, this is very important. If someone can be determined to be killed and the other party's identity can be found, the subsequent case investigation will be easier. However, there is one thing that has not been analyzed in place on the Guangming District Branch, that is, why did the suspect set fire to the warehouse? There is nothing valuable in the warehouse. If it is for revenge or other reasons, is it necessary to do so? So, is there any relationship between the suspect setting fire to the warehouse and the victim? As long as this relationship is clear, the case is solved for granted.
Lu Chuan will deploy other work tasks next.
"Second, Wang Shuai led the team and acted as a group to investigate the relevant information of the dead. Start with the information of jeans. I have worn this pair of jeans before. It is a luxury brand abroad. The price of a pair of jeans costs about 2,000 yuan. It is relatively cheap. There are very few specialty stores in Haizhou City, and most of them are purchased by members. Check this aspect to see if you can find useful clues." Lu Chuan said.
After Zhang Hui and Wang Shuai were arranged for the tasks, Lu Chuan looked at Ren Qiang.
"There is another clue. Brother Qiang, you have to take action." Lu Chuan said.
Although Zhang Hui and Wang Shuai are both able to stand on their own, they are both good at the Criminal Investigation Detachment, and each leads the team to perform tasks independently. However, compared with work experience and leadership, Ren Qiang is still much better than the two of them. Another important reason why Lu Chuan let Ren Qiang take action in this last work task is that there was a detail in the case analysis process, neither Wang Shuai nor Zhang Hui discovered it.
Although Ren Qiang is now the deputy captain of the Criminal Investigation Detachment, he has no resistance to Lu Chuan's arrangement of tasks for himself. In the Criminal Investigation Detachment, even the captain of the detachment, he had to go to the scene when the case came. Although Lu Chuan is arranging his work, he actually takes into account every job, and sometimes he even ends up in person.
"Lu Zhi, you arrange it and ensure that the task is completed!" Ren Qiang said.
Although Lu Chuan is called Ren Qiang and Ren Qiang, Ren Qiang cannot rely on his seniority. At this time, this was a formal meeting venue, so Ren Qiang called Lu Chuan or position. This is not only a respect for the position of captain of the Criminal Investigation Detachment, but also a recognition of Lu Chuan.
Lu Chuan nodded, spread out the file in his hand and put it in front of Ren Qiang.
"The investigation of these books," Lu Chuan said.
Two important clues were found at the fire scene, one of which was half a burnt photo of someone suspected of being killed, and the other most important clue was the burned account books.
"Although some information on these books cannot be effectively tracked and the heads of the questions have been burned, these books can still provide us with some clues, which may lock in where these books are revealed." Lu Chuan explained.
In fact, the Guangming District Public Security Bureau also handled and analyzed these books for a certain amount, but found no valuable clues. In addition, the Guangming District Public Security Bureau did not invest much effort when investigating this clue. Most of the numbers in these books have been burned out, and some have completely disappeared. The books found at the crime scene were also soaked in fire water, so the handwriting on it was blurred, making it very difficult to identify it. In addition, even if it was identified, there was no need to identify it.
However, when Lu Chuan carefully read the photos of the remains of these books, he found a secret clue.
"In the photo of the 56th number, everyone carefully look at the lower left corner of the account book's wreckage." Lu Chuan said. Everyone opened the file in their hands and found the on-site survey photo numbered No. 56.
"Let's see, what's special?" Lu Chuan asked.
special?
Several people picked up the photos and observed them carefully. The writing of the account book on this photo has been blurred and is a little blurred, but you can basically see the original number clearly, but it does not have much effect.
"Lu Zhi! Did you say... the watermark?" Liu Guodong was the first to see the clue. The other party deserves to have many years of experience in on-site investigation and soon discovered some special places in this photo.
After Liu Guodong reminded everyone, everyone focused on the so-called watermark. It was indeed that the picture on the account book in the lower left corner of this photo had some blurry gray marks. This trace is a bit like the scar after the ink rendering is opened.
If it weren't for Lu Chuan's reminder, everyone might not have discovered it at all. This is actually a watermark.
Lu Chuan nodded.
"Yes, although this trace is a bit like a scar after ink rendering, it is actually different. Everyone sees that there are no burrs on the edge of the scar, and it is relatively neat and smooth, so it is very likely that this is a watermark. Of course, this is not particularly certain." Lu Chuan explained.
All you see now is the photo. Although this photo is still quite fidelity, there are still some reflections. Lu Chuan needs to see the original account to make further confirmation, but based on his experience in on-site investigation, the possibility of a watermark is relatively high.
No mistakes, one song, one content, one in 6, one book, one bar, one reading!
If there is indeed a watermark on the back of this account book, it is very likely that the source of the account book will be found based on this watermark.
"Brother Qiang, you should follow this clue. Check all the remains of these books carefully, pick out all the watermarks like this, and then let the technical team process it. If possible, find the components of these watermarks from it, so that the source of these books is likely to be found. If tracking at that time, there are very likely to be some unexpected discoveries." Lu Chuan said.
It is actually understandable that the account books appear in the warehouse, such as recording some ledgers entering and leaving the warehouse. But the amount should not be particularly large. The books found at the arson site now have obviously exceeded the normal books that ordinary warehouses should have, and these books are printed on them and are not recorded manually at all, so there must be other reasons why these books appear in the warehouse. Lu Chuan decided to start from this aspect and see if he could find out. (This chapter ends)
