After thinking about it, he said: "This seems to only prove that the murderer has bought black fish recently, but I am afraid it will not help our investigation work, black fish is also a relatively common fish, and it is sold in the vegetable market in Da'an New Village, plus in the past few days, the boss may not remember."
"It's always a direction, a pointing clue.
"In many cases, not all clues can be directed to a specific suspect or suspects.
Especially in the early stage of handling cases, as long as it can help us circle a general range and reduce the workload, it is enough.
You have been handling cases for so many years, and you will not fail to understand this truth. ” Rong Shiming scratched his head.
Of course he understands this.
It's just that maybe it's Yuan Youchong who is a myth, he always feels that Yuan Youchong personally took action, and this case should be caught, and the clues that Yuan Youchong attaches so much importance to should be extraordinary, and it is common sense to point directly to the suspect.
With just one glance, Yuan Youchong roughly understood what Rong Shiming was thinking.
Obviously, he thought too highly of Yuan Youchong.
No matter how smart Yuan Youchong is, he can only make logical reasoning on the basis of clues and evidence, without clues, he is also at a loss, it is difficult for a clever woman to cook without rice, if you get rid of clues and evidence and analyze yourself, what is the difference between it and nonsense What's more, in today's highly developed criminal investigation technology, and at the same time relatively heavy on evidence and light on testimony, the impact of XGJG's personal ability on whether or not to solve the case is actually getting smaller and smaller.
The role of elites such as Yuan Youchong and Yu Chen is more about improving the efficiency of solving cases, accurately determining the direction of investigation according to various clues and evidence, and avoiding detours, rather than increasing the rate of solving cases.
Relatively speaking, the current XGJG system lacks grassroots police forces, not elite backbones, and talents abound.
Zooming in to the entire public security system, the problem lies in the lack of manpower in the departments that are in charge, and the lack of manpower in the departments that do not have the ability to do so Retracting his thoughts, he explained: "If the boss remembers it, it doesn't matter, just take a picture of the surveillance."
Combined with the characteristics of the black fish and the color of the bag, the vendors who match the requirements are screened out, and then the monitoring is retrieved, and the monitoring will be stored within the time range of a week, and all the people who have bought the black fish are determined. ” "Okay," Rong Shiming pursed his lips and muttered, "It's just that this workload is too much, I'm afraid it will take a long time to figure out the reconnaissance." ” "Time can be given, I'm afraid they won't do it."
Yuan Youchong shook his head: "Didn't you leave a batch of reserve police forces before, can you send them out." ” "Okay."
Rong Shiming bowed his head, immediately took out the walkie-talkie to arrange the task, and then asked: "Then let's go to the picture detective to ask now."
"Hmm."
As for the Graphic Investigation Bureau, little progress has been made.
There is no way, the monitoring density of the target area is really too low, and I am afraid that there are only a little more probes in supermarkets and vegetable markets, but it was late at night when He Rui disappeared, and the supermarkets and vegetable markets had long been closed, so it was naturally impossible for XGJG to waste time in this regard.
Yuan Youchong was a little disappointed, but it was also expected.
There was no progress in this regard, so Yuan Youchong simply joined Rong Shiming and joined the investigation work.
After all, He Quanzhong and his wife still had conflicts with others, and although the contradictions were small, they had to go through a meticulous sieve to determine or rule out their suspicion of committing crimes.
At the end of the day, several investigation teams found nothing, neither locked the suspect nor found new body parts, and the surveillance of several fishmongers was reversed, but it obviously took a day or two or even longer to finish the video.
In order to catch up with efficiency, they could only find a person who met the conditions of the initial screening, that is, bought the black fish, so they intercepted it so that the technology could be clarified and sharpened, and then passed it on to the investigation team to determine the identity of the other party.
Fortunately, due to the ferociousness of the black fish and the heavy fishy smell, it is more troublesome to remove the fish, but at the same time, the advantages are quite clear, such as good meat quality, less broken bones, large amount of meat, etc., resulting in a relatively concentrated buying crowd In other words, although there are many people who buy blackfish, the overlap rate is also quite high, and if you screen for the characteristics of suspects, the scope of the investigation target will be much smaller.
But again, it takes time to screen out the targets one by one.
The people screened out, Yuan Youchong did not rush to investigate with this method, although the investigation area can be greatly reduced, but in the end, there may still be forty or fifty people, or even more, and other conditions need to be further eliminated.
Moreover, just because of the condition of buying a black fish, it is impossible to continue the investigation.
Seeing that it was getting dark, he simply pulled Gu Yandong and Lei Huailu, and went to ask the square dance aunts and uncles again.
During the day, the visit to them was not very successful, so I took the opportunity for them to get together and dance together, and asked them again.
Well, he didn't bring Rong Shiming, because he was not used to cooperating with him, and there was no tacit understanding between them, which was quite embarrassing.
I asked several groups of people in a row, but they didn't get anything, they didn't see any suspicious people or things at all, or even if they did, they forgot about it after a few days.
Lei Huailu was a little disappointed and said, "Team Yuan, I think" "Don't think about it, there are still four groups of people, go back after asking."
Yuan Youchong interrupted him with a wave of his hand.
He had to hold back his words. asked two more groups of people, and finally let Yuan Youchong get a clue.
The eldest sister of a "leading dance" said: "If you want to say that you see any strange people, there is really nothing, but if there is a strange thing, there is someone who has not come in the past few days."
Lei Huailu said: "It's not surprising that I have been on vacation recently, and I may have gone out with my family." ” "No, no," the eldest sister waved her hand and said, "I didn't even count the ones who went out to play."
Well, you see, we're more than half as many people as usual. ” "He, he told us before that he might go out with his family on National Day, but he came again on the 30th, and I was a little strange, so I asked him, and he said that his son and daughter-in-law had gone out, and he wanted to follow, but he was too lazy to move, so he didn't want to go."
"As a result, he hasn't been here since the beginning of No. 1.
Well, he's been dancing here for a long time, and he's coming every day, plus he first said that he was going out to play for a few days, but he didn't go, and now he doesn't come, I'm more impressed. ” Yuan Youchong thought thoughtfully: "Then, do you know what his name is?"
