The Traces Division and the Investigation Team soon went to Dou's home to investigate. \ On the bookcase, as well as on the surface of the box containing the dagger that Dou Maobang said, they really extracted a large number of fingerprints and palm prints.
In the comparative test, there are indeed several sets of fingerprints that match the fingerprints of Dou Kun's bound ID card.
But the problem is that Dou Kun had already taken the high-speed train back to his hometown three days ago, and he was able to check his ticket purchase records and ride records.
From this point of view, he also does not have the conditions to commit a crime.
This clue is broken at this point, and if you want to continue the investigation, you either have to call him over and ask him carefully who he gave the dagger, or launch an investigation into Deng Xilin's interpersonal relationships and lock in a new suspect.
True, the nature of the case is not difficult to define.
Obviously, the perpetrator's target for the murder was very clear, that is, Deng Xilin.
Among the common motives for killing, the three categories with clear directions are nothing more than emotional killing, vendetta killing, and financial killing.
Obviously, all three types of investigations can be carried out from the point of investigation of the victim's interpersonal relationship.
In fact, even though someone reported the discovery of a dagger this morning, and the dagger was eventually turned out to be a murder tool, and fingerprints were extracted from it, the detachment did not ease the intensity of Deng Xilin's interpersonal relationship.
And Yu Yuan and the others had already sent someone to Deng Xilin's hometown to cooperate with local colleagues to investigate.
Therefore, what the detachment needs to choose is only whether to continue to follow up on the line of the murder weapon.
Without too much entanglement, they decided to carry out the two lines together, and sent an old criminal policeman to the local area with a letter of introduction, asking local colleagues to cooperate, and bring Dou Kun back to cooperate with the investigation on the grounds of suspected theft and involvement in a homicide case.
"Alas," after arranging the task, Yu Chen sighed in annoyance and said, "It's just that Deng Xilin doesn't live in the city permanently, and if you want to find out if he has any enemies, you can only go to Tunqing, it's too troublesome." ” "What's the solution?"
Yuan Youchong shrugged his shoulders and said, "Of course, we have to do some work too."
Aren't the supermarket owner and Deng Xilin fellow villagers Deng Xilin invited him, and it is necessary to invite him to come over and ask questions. ” "yes, I was so busy that I forgot."
Yu Chen slapped his forehead and said, "I'll send someone to invite him to our detachment and ask questions." ” "Also," Yuan Youchong said again: "Places like stations, airports, etc., arrange good people to watch them, but don't let the gangsters slip away." ” Yu Chen waved his hand: "This is assured, I can't forget it."
In addition, do you want to check our Tunqing residents in Xin'an and go through the sieve?"
"That's not going to work."
Yuan Youchong shook his head: "Residents whose household registration or ancestral home is Tunqing, I estimate that tens of thousands of people can be pulled out at least, and after going through the sieve like this, you have to find out the Year of the Monkey."
"Then check the Tunqing people who came to Xin'an recently" "That's a lot," Yuan Youchong rolled his eyes: "I have thought about this idea for a long time, and I have also conducted an investigation, and I learned that in the past few years since the high-speed rail was opened, in the direction of Xin'an, there are six trains that stop in Tunqing every day, and the population flow between the two places is an average of hundreds or thousands of people per week." ” "Although it is said that the vast majority of them are Xin'an residents who set off from Xin'an and go to Tunqing to stay in the hot springs for a day or two and then come back, there are many Tunqing people, which have to go through a sieve, and the workload is also huge."
"Even if it is only to screen out the Tunqing nationality, and then pick out the passengers who are not residents of Xin'an, who do not often travel between the two places, etc., and then select the suspicious objects from them, it is also quite a huge work, I am afraid that at least five people will have to be screened overnight for a day or two before there is a result."
"Not to mention, such a screening, the result may not be accurate, in case the gangster is a permanent resident of Xin'an, in case he often travels between the two places, in case he is a local Tunqing person, there are too many uncertain factors, in the end, it will be a waste of work."
"So, your proposal is not feasible at all, and it has no operational value."
Yu Chen scratched his head: "Then what else can we do now?"
"Don't mess with your spirits."
Yuan Youchong pouted: "Everything that can be done has been done, next, let's go on step by step."
I think that although this case will be more cumbersome in screening suspects, as long as the suspects are confirmed, it should not be difficult to detect. ” "yes."
Yu Chen said: "How can there be so many high-IQ crimes, right?
” At one o'clock in the afternoon, Deng Boliang, the owner of the supermarket, arrived at the detachment to cooperate with the investigation.
"I don't have much to do with Deng Xilin, in fact, we don't have much intersection."
Deng Boliang said: "My hometown is in the same township as him, I know him, and I know that he sings well, so I invited him to come to a small performance this time, and he offered a fair price, saying that for the sake of his fellow villagers, he could give another 500 yuan for board and lodging tickets." ” "You say, where can I find such a cheap price, when I first went to his house to invite him, I was ready to have some blood.
Not to mention anything else, I hired two makeup artists for 1,080, and I also invited two small song and dance troupes, one 5,500 and 18,000. ” "Look, you can see how fair he is by comparison, not to mention, he sings much better than those two song and dance troupes, that is, he is older, and he is not handsome, so he can't attract the young now, otherwise I think he will do a live broadcast or something, and then hype and hype, he will definitely be popular."
"So, although I don't know him well, I can also see from this that he should be quite righteous, how could he be harmed by others?"
Yu Chen put a pestle on his forehead in one hand, quickly went through the transcript he had just written, and asked, "So, you don't know who he offended."
"I really don't know this" Deng Boliang shook his head, thought about it, and said: "However, I know a person who is familiar with him, who is his cousin, and is also developing in Xin'an, when I went to invite him, I also came to the door in advance to ask his cousin to help me talk to him on the phone." ” "After all, he is the first of the top ten singers in our Tunqingna, I always feel that capable people have a bad temper, at least not very easy to invite, and it is not worth the price to spend too much."
"Originally, it was just a lively show to attract passers-by to do promotional means, but I didn't expect him to be so easy to talk to, anyway, I think he is very easy to get along with and easy to talk, and a guy who can have a mortal enmity with people like him must be a person with a small belly."
Yuan Youchong automatically packed up his subjective evaluation of Deng Xilin and threw it into a corner of his mind, not thinking about it for the time being, so as not to affect his supervisor's judgment, and only said: "Please provide his cousin's contact information." ” "Hey, okay, his name is Deng Xizhong, he is in the clothing business, he lives near Lao Cai, and the phone number is" Writing down this clue, Yuan Youchong said: "Last question, when the crime happened last night, where did you have anyone who could prove not to misunderstand, I didn't suspect you, I just wanted to rule out your suspicion of committing the crime."
