Back at the city bureau, several people came to Yu Chen's office again.
No way, there are not many of them, they can't go up or down, go to the conference room, even a small meeting is a bit wasteful, the office, except for Yu Chen's office, even Yuan Youchong's office is a bit crowded, so I can only come here.
On the way, Zhou Qianxin slapped herself and the rest of the people for a long time.
No way, the term slap length seems to be relatively clear, but it is still a very vague concept when used in forensic science accurate to the millimeter.
The most basic point is that everyone's slap is not the same length.
In addition, it is about the length of the palm, whether it is slightly longer or slightly shorter, and there is no way to compare.
In order to determine the identity of the murder weapon, accurate data is indispensable, which is also the fundamental reason why the forensic report clearly stipulates that specific data must be used, and other items cannot be analogized.
Therefore, until she returned to the conference room, she could not be sure whether the murder weapon depicted by Wei Yiyi was the same as the one that killed Xu Hui's family.
After all, there are many types of double-edged stabbing weapons that are "about the length of a palm".
In this way, the only common points between this case and the case of Xu Hui's family being wiped out are the similarity of the murderer's modus operandi and the similarity of height.
Among them, the modus operandi can be imitated and learned, and the height does not explain the problem, so it is a bit reluctant to combine the cases for investigation.
Therefore, everyone's eyes fell on Yu Chen and Yuan Youchong, waiting for them to decide.
"If you combine the cases and investigate, you have to allocate a little police force."
Yu Chen said: "In this way, the already stretched police force will be even more nervous."
If the perpetrators are the same person, that's fine, but if it's not the same person, the police force will undoubtedly be wasted. ” "It can't be said to be wasteful."
Yuan Youchong had the opposite opinion: "To say a word about the main theme of Weiguang, it is our obligation to ensure the safety of people's lives and property."
"Don't, ruffian hanger, you suddenly say such things, and my goosebumps are up."
Yu Chen complained mercilessly.
"Cheng, I don't want to say it anyway" Yuan Youchong said indifferently: "That's what it means anyway."
According to our speculation, the purpose of the assailant encountered by Dai Qi may not be robbery, but murder."
"Before you went to Menchang New Village, didn't you refute Xiao Ji's opinion" Yu Chen interrupted him: "I still remember that you said at the time that in the process of committing the crime, the mentality of the robber and the robbed was not very stable, and it was possible to do anything. ” "But as I said, Xiao Ji's opinion makes some sense."
Yuan Youchong said: "Although most of what we do is the work of making amends, the murderer committed the crime, and we will arrest the murderer again, but it does not mean that we can only remedy it afterwards, nor does it mean that we are willing to do so." ” Since the murderer's goal may be to kill people, if it doesn't work that time, he may plan to act again, that is, the safety of Wei Yiyi's family is threatened.
If we anticipate this possibility, why don't we find a way to avoid it?"
"Therefore, you tend to investigate the cases together" Yu Chen asked: "Even if the perpetrators of the two cases are not the same person, at least the perpetrators of this incident in Menchang New Village will be caught, so as to protect Wei Yiyi's family."
"That's what it means."
Yuan Youchong nodded: "Moreover, the Zhongzheng Xincun murder case has reached a stalemate, even if the police force is still fully invested in it, there may not be any progress, why not report the attitude of giving it a try and merge the two cases."
Yu Chen frowned: "I have no opinion on this case in Chang New Village, but I don't agree with the merger, so let's check each one." ” "Oh" "In the case of a joint investigation, it is definitely necessary to investigate the similarities of this case, investigate the connection between the victims, and find the murderer.
But if the two cases are not related, the case of Menchang New Village will be contained by the Zhongzheng New Village Murder Case, and even miss the best time to solve the case, allowing the murderer to escape. ” "Not all cases, the combined investigation can play a role in promoting, if the two cases are not related, choose the wrong direction, it will only lead to the progress of the investigation of the two cases being dragged down, you should know this better than me."
"That's right."
Yuan Youchong nodded and looked at the silent others: "Well, we can now say that we have decided to intervene in the investigation of Wei Yiyi's case, but whether to merge the case or not, you can also give an idea, don't sit there and act as a background." ” "I have an opinion," Lei Huailu said, "Let's go hand in hand, send a few people to Xiao Ji, let him focus on and follow up on the case in Menchang New Village alone, and let's investigate the two cases together, anyway, Menchang New Village is within the responsibility of Xiao Ji's police station." ” Several people looked at each other and nodded.
Yuan Youchong said: "It's barely a solution, let's do it first, I'll call Xiao Ji." ” As he spoke, he took out his mobile phone, told Ji Hongchang about the matter, and assigned him a task.
When he hung up the phone, Zhou Qianxin suddenly hesitated and said, "That, I have a discovery that I don't know if it's a discovery."
"Why is this so awkward" Yuan Youchong plucked his ears and said speechlessly: "How many times have you emphasized it, if you have anything to say directly." ” "Isn't it for fear of interfering with the direction of the investigation?"
Zhou Qianxin licked her lips and said, "That's the case, I found that Wei Yiyi and Xu Hui are of the same age, and their body characteristics are relatively close, and she also lived in Zhongzheng New Village before. ” "What do you mean" Yu Chen frowned, thoughtful.
"I can't say for sure."
Zhou Qianxin smiled bitterly: "When I thought of this, I felt that my spirit flashed, but I couldn't grasp my thoughts, and I thought about it all the way to no avail." ” Yu Chen looked at Yuan Youchong, but saw that this guy was also deep in thought.
Helpless, he had no choice but to make up his own mind, waved his hand and said, "Cheng, I know, I'll think about what happened when I look back." ” "Xiao Ji's task has been explained, so the task of our detachment is to carefully collect information about Xu Hui's family and Wei Yiyi's family, and at the same time investigate their interpersonal relationships to see if they can find a connection."
"Since the cases are to be investigated together, the perpetrators of the two cases are regarded as the same person.
As long as there is a conflict with a member of the two families at the same time, there is a suspicion of a major crime, and biological materials that can be extracted such as blood or oral epithelial cells are immediately collected and sent to the forensic genetics laboratory. ” "Xiao Zhou, the task of extracting samples will be handed over to your forensic department, and it will be hard these days."
"No problem."
Zhou Qianxin agreed: "Anyway, I've been running around before, I can't remember how many samples I have taken, and it doesn't matter if I run for a few more days." ” "That is, testing DNA also costs money, and a lot of money has been burned to test so many materials before, and our detachment has not enough funds."
"You don't have to pay for it" Before Yu Chen finished speaking, Yuan Youchong suddenly raised his head and stared at Zhou Qianxin: "Xiao Zhou, you just said that Wei Yiyi's body characteristics are very similar to Xu Hui."
"Uh, Team Yuan, your reflex arc is too long" Zhou Qianxin blinked, and then nodded: "Well, I just said."
Why, you've got an idea."
"Yes, but" Yuan Youchong smiled bitterly: "It's a bit unbelievable, it shouldn't be" Punishment and murder :
