National Forensic Doctor

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.

Key evidence. "

Huang Qiangmin has been the captain of the criminal police team for many years, and he is quite experienced in such murder cases. He looked at Jiang Yuan with some satisfaction.

Huang Qiangmin guessed that when Jiang Yuan asked to collect the physical evidence, he specifically mentioned the door lock, which 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 there a lack of evidence directly pointing to the murderer, but the various evidences in the room were also insufficiently probative.

——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 to win 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. "

"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 phone. Basically

Next, there is a possibility of not having a lover. "

The rest of the evidence is nothing more than that. After checking the cell phone, he is still innocent. There is a small chance that he is not innocent anymore.

However, criminal police officers 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 commit adultery 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 unlocking method is classic, and the unlocking traces left behind are naturally not typical. The less lock-picking training you do, the more fixed your lock-picking movements will be, and the more stable the marks will be.

In the early years, when burglaries were more prosperous, some skilled police trace inspection experts could only identify the technical unlocking marks on the locks. They could also identify some famous local thieves based on the identity of the marks. traces of operations.

The atmosphere in the room became dull for a while. Huang Qiangmin looked calm 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 home invasion murders 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 in terms of solving 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 among those involved are often unconventional.

Lang Heng could immediately remove the lock and use tools to explore it first.

"Do you want to ask Lao Liu to take a look?" Huang Qiangmin still knows how to use 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 task force from back then. If it's a case 10 years later, all the people from that time will still be there." Zhong Tao said.

"If you want to make it work, let's find a few less members of the former task force. It should be difficult to make a purely technical breakthrough in that case." Although Jizi 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" unlocking 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 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 also means that no one has used the door to pick the lock, or sprayed it with a 97-2 explosion-proof gun. There are actually only two ways left to unlock the door, one is key unlocking and the other is technical unlocking.

"The locks are coming."

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 Deli... really doesn't have anything. Well, you can reorganize the task force according to the personnel list of the 430 task force 10 years later. Although if the personnel are not It has changed, but those who are still in the detachment and in Jingle City, please try your best to transfer them over!"

"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 king of locks and thieves in the new era is no longer a genius of mechanical locks - 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, what is written in the withdrawal file is completely consistent with Xiaojia's daily experience and memories. At the very least, the things in the files must withstand scrutiny, especially the files of the judicial department. Even if it is an investigation file, the things outside are very strict.

of.

However, whether there were bloodstains in this case, Lang Heng's bloodstain analysis skills would not be able to be used, and Huang Qiangmin felt a little regretful. In my mind, apart from the various technical methods Lang Heng had mastered, that trick was extremely useless.

Whether Jiang Yuan followed Zhong Taoxian's guess or not, 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 does not have the LV6 tool mark identification skill, but it is very suitable to use it outside, because the first thing needed now is to find the mark, but to determine who the mark belongs to. ⬣Reminder: Share this website reading sᴛᴏ𝟻𝟻ᴄᴏᴍ on Facebook, please move your fingers, so that we can continue to operate⬣
