While waiting for the extraction of physical evidence, Lang Heng accompanied Jiang Yuan and looked at the pictures of various exhibits with the criminal police present.
This case involved a lot of physical evidence. Due to the failure of the investigation by the task force, a lot of physical evidence was extracted. However, after looking at the photos of all the physical evidence, Huang Qiangmin felt something and said: "The windows are all sealed, and the doors are closed." It's the only way in and out. The door lock... can be said to be closed.
It’s a key piece of evidence.”
Huang Qiangmin has been the captain of the criminal police team for many years and is quite experienced in this type of murder cases. He looked at Jiang Yuan with some satisfaction.
Huang Qiangmin guessed that when Jiang Yuan asked him to collect physical evidence, he specifically mentioned the door lock. It was most likely just an intuition. Because at that time, Jiang Yuan did not have complete evidence information and did not know the evidence in the case. Not only was it missing The evidence directly pointing to the murderer and the various evidences in the room are not strong enough.
——It would be even better if it was not intuition but an inference that could be made without complete evidence and data.
Huang Qiangmin feels that he really deserves a Bole Award or something like that!
"We have also checked the door locks before." Lang Zi knew what Jiang Yuan and others meant, and said: "Actually, it is precisely because we checked the door locks that we grabbed Mai Zu. The door locks of the victim's house did not have typical locks. There are traces of unlocking, so the murderer most likely has the key, or he must have tricked the door into opening."
"There is a key... maybe he is a lover?" Huang Qiangmin was not trying to argue, but just raised a possibility.
Jiang Yuan shook his head slightly: "You guys asked about the situation sideways. The victim Yingxue is very busy raising two children. You are a full-time housewife. You have to buy food, cook, and pick up and drop off the children every day. You and your I have also chatted with a few of my best friends, read your WeChat, and checked the software on my mobile phone. Basically
Well, there is a possibility that you don’t have a lover.”
The rest of the evidence is nothing more than that. I checked my cell phone and found that I was innocent. There is a small chance that I am not innocent anymore.
Yes, criminal police have always been activists. Huang Qiangmin never asked: "Will there be a seventh mobile phone?"
Lang Hengzai checked it carefully and pondered.
"What should I say?" Zhong Tao looked at me and calmed down.
Moreover, social media 10 years from now will not be as prosperous as it is now, and Xiaojia will still not be able to meet online, hook up online, or have sex online.
LV4's crime scene investigation and even LV3's vehicle trace identification can also play a certain role at this time, but they can only provide a little help and cannot solve the problem.
The lock-picking method is a classic one, so the traces left behind are naturally not typical. The less training you do in unlocking, the more fixed the lock-picking movements will be, and the more stable the traces left will be.
In the early years, when burglaries were more prosperous, some skilled police trace detection experts could only identify the technical unlocking marks on the locks. They could also identify some famous local thieves based on the nature of the marks. traces of operations.
The atmosphere in the room became dull for a while. Huang Qiangmin looked at it calmly and said: "It's a pity that there are no blood stains at the scene. Otherwise, Zhong Tao would have used blood stains to detect the home invasion murder case once or twice."
However, those files serve the court, or in other words, serve fairness and justice. And it is difficult to get answers from information that is too conventional for the purpose of detecting cases.
"At most, the lock has been opened by bumping into the lock." Lang Heng's answer was similar to the subsequent trace inspection judgment of the task force.
A small number of technical lock-picking techniques are not used by lock-picking masters. Common lock-picking techniques do not use hooks or tinfoil.
Jiang Yuanyou said that there are not many cases that exceed the state of mind of a special person. In literary terms, it is lower than the level of living, especially cases involving love murder. Think about it, the murderer would be willing to do it. To kill someone, the emotion must be extremely strong, no matter what people think,
The emotions between those involved are often unconventional.
Lang Heng can immediately remove the lock, first use a tool to explore it.
"Would you like to ask Lao Liu to take a look?" Huang Qiangmin still knows how to employ people. Seeing that Lang Heng was deep in thought, the first thing he thought of was to use Liu Jinghui.
It cannot be said that this is an extremely bad example of people being afraid of being famous and pigs being afraid of being strong.
"You can really see very little in the blood stains." Zhong Tao agreed.
"You can't bring back the special case team from back then. If it's a case 10 years later, all the people from that time will still be there." Zhong Tao said.
As for the police's trace inspection, there is no professional response method. The so-called "technical unlocking through typical trace identification."
"If you want to make it work, let's find a few less members of the former task force. It should be difficult for that case to be purely based on technical breakthroughs." Although Ji Zi has just finished contacting the case, as far as my technical level is concerned, it seems that At first glance, I found that the case was definitely not difficult.
Zhong Tao put on his gloves and scanned through the evidence bag. First, he asked everyone to make room and checked the locks.
It also activates "typical" and "stable" unlock traces.
Huang Qiangmin chatted and thought to himself, he said very little and you said very little, which is a very little.
Today's technical methods are naturally more advanced and complete, but the number of home invasion cases has made the development of this type of technology lag behind.
Zhong Tao actually agreed, nodded, and then said: "Yes, if you want to invite Liu Chu, you have to collect less information and make more mistakes to avoid harm."
First of all, the lock has not been treated with violence. It is hard to say that anyone has used the door to pick the lock, or sprayed it with a 97-2 explosion-proof gun. There are actually only two ways to open the lock. One is One is key unlocking, and the other is technical unlocking.
"The locks are here."
Whether Sui Yingxue is in the family and has no love debt, Jiang Yuan can guarantee it for you.
Jiang Yuan didn't understand and muttered to himself: "Liu reasoning... really doesn't have anything. Well, you can reorganize the task force according to the personnel list of the 430 task force in 10 years. Although if the personnel are not There have been changes, but those who are still in the detachment and in Jinle City, you should try your best to deploy them here!"
"Did you find the seventh mobile phone?" Jiang Yuan paused and said: "Unless you put the seventh mobile phone outside your home, the scene was turned upside down. Did you also have a workplace? …Of course, that possibility is also ruled out.”
The guest house of the criminal police detachment receives three task forces on a daily basis. Even outside the restaurant, the waiters are unfamiliar and use screens to surround a separate space.
"You think of a way." Jiang Yuan nodded.
Because technical lock-picking is actually a new invention, or in other words, various inventions were broken as early as decades later. The lock king and thief king of the new era is no longer a mechanical lock genius - from this If there is no technical unlocking method, there will be no traces.
The police officers brought in several boxes of broken evidence one after another.
It requires blessings such as unspoken rules. In any unit, the things written in the withdrawal file are completely consistent with my daily experience and memories. At the very least, the things in the file must withstand scrutiny, especially It's a file from the judicial department. Even if it's an investigation file, everything on the outside is very precise.
of.
However, whether there were bloodstains in this case, Lang Heng's bloodstain analysis skills would not be able to be used. Huang Qiangmin felt a little regretful. In my mind, apart from the various technical methods Lang Heng mastered, that trick was extremely useless. .
Did Jiang Yuan follow Zhong Taoxian's guess and want to go up? He still placed his hope in Lang Heng.
Zhong Tao sighed and said, "Looking at it that way, that road is still open."
Lang Zi's probe rummaged outside the evidence box, and then said: "That case may really require Liu Chu to develop some ideas. If not possible, we should find a few less members of the task force. Things without memories are better than files. Things outside are still vague.”
Zhong Tao was doubtful, and looked over and over at the removed lock. To be honest, Lang Zi didn't have the LV6 tool mark identification skill, but it was very suitable to use it there, because now first of all What is needed is to find traces, but to determine who the traces belong to.
