Chapter 681: Although Not Necessary, But

The car arrived immediately, parked directly at the entrance of the residential area, and Team Leader Jiang, you can go downstairs." Qi Changye spoke until his mouth was dry, and his voice was a little hoarse.

His mood was quite excited, but he held his mobile phone for too long, talked too much, used his brain for too long, plus he hadn't slept for several days, he was slightly unable to hold on.

At this time, a somewhat strange and familiar voice came from Jiang Yuan's side: "Bring some meat to those colleagues of yours. I put the seasoning bag next to it. Actually, it's fine without dipping the seasoning. The meat we cook is fragrant even if you eat it with your mouth."

"Good. Then bring two boxes, they look quite hungry." Jiang Yuan handed the box handed over by Jiangfuzhen to Qi Changye.

The box was specially customized in the early years. It is very convenient to give gifts or bring it yourself. It contains meat, and there are positions for simple bowls, chopsticks, and seasonings. If you go camping, you can eat it when you unfold it.

Jiangfuzhen then asked the chefs to quickly pack a box of beef, thought about it, and matched a box of buns and pickles. It is said that meat with carbohydrates is not exchanged for a county magistrate. For the level of cadres in the capital, it is just right.

Qi Changye held his mobile phone, listened to the words on the opposite side, and said in a very embarrassed low voice: "Team Leader Jiang, it's better not to bring it. We are at the scene, and we can't eat at the scene..."

"Who eats at the scene, let him come to the laboratory to look at the microscope." Jiang Yuan first reacted, and then said: "You can eat outside the cordon. It is best to find a place indoors. At the same time, change all the gloves, head covers, etc., and change them when you enter the scene again..."

Without waiting for Qi Changye's response, Jiang Yuan packed up, ended the call, and called Mu Zhiyang, Wang Chuanxing, and others, totaling 6 people.

Facing the second murderer now, he is the master who can retreat from Qi Changye and his professional colleagues. Jiang Yuan doesn't want to explore how professional he is at all.

And 6 police officers who have received professional training gathered together. Without using thermal weapons, defense is no problem.

Meilin Garden.

The police car with traffic police motorcycle clearing the way arrived at the crime scene in only 20 minutes.

Jiang Yuan said thank you and hurried upstairs.

Now is the time to race against time. For traces like blood pools, before they solidify, they can be judged by the minute. But once they solidify, because you don't know what time it completely solidified, the judgment of the time of death is at least a quarter of an hour of error.

Fingerprints, DNA, or other biological materials, including trace evidence, certainly have the advantage of long timeliness, but they are definitely the fresher the better.

Those ancient fingerprints might need an LV3 fingerprint expert to compare, but fresh ones might be handled by Wang Zhong.

And a more likely situation is that some materials change over time, either they deteriorate, or they are biologically decomposed. The investigation personnel cannot see them at all, let alone talk about quality.

"Beef for you." At the door of the residential house where the incident occurred, Jiang Yuan handed the meat box given by his father to Qi Changye.

Qi Changye thanked him repeatedly, and sighed: "I'll let my colleagues eat first, I'll accompany you in."

"You send a few people to pull up the warning net, so as not to let the second murderer return." Jiang Yuan said very seriously.

Qi Changye was stunned: "Generally not."

"Safety first." Jiang Yuan said, dressed neatly, and started to enter.

Mu Zhiyang followed behind, and by the way, pouted at Qi Changye: "You eat some meat and rest, send people to send people, don't follow, it's quite tired."

Qi Changye was also tired, and was pointed out by Mu Zhiyang, and suddenly realized, "I send, I send..."

Qi Changye also stretched his neck and whispered: "Team Leader Jiang, we found the image of the second murderer in the surveillance nearby, just lost the track later."

"Is there an image of the murderer? Let me see?" Jiang Yuan explained: "If there is a video recording, you can determine the murderer's gait and posture, which is helpful for footprint analysis and bloodstain analysis."

Qi Changye hurried to promise, and after a while, he brought a laptop back.

"Mainly these few videos." Qi Changye first played the video of a surveillance camera near the building, which could clearly see the physical characteristics and body characteristics of the second murderer, but the face was covered by a mask and sunglasses, and it was almost unrecognizable.

"The accuracy and clarity of your camera are better than what we use in Ningtai County." Jiang Yuan praised.

Qi Changye felt praised, smiled twice, and felt something was wrong, and hurriedly said: "It's not much better, mainly because the capital's requirements are high. When choosing, the needs are different... It's also because this case is urgent, we first searched for cameras with relatively high clarity."

"Theoretically, you can borrow the skull restoration technique to restore the facial features of the second murderer, but this will take several days..." Jiang Yuan's first half almost lit up Qi Changye's eyes, and the second half made his eyes drift.

Qi Changye whispered: "Actually... a few days is fine. Although this case is urgent, it is not urgent here..."

Jiang Yuan waved his hand, interrupted Qi Changye's words, and had already transitioned to the second surveillance, and said: "Look at the murderer's gait, the military temperament is still there, it should be a long-term continuous exercise state. If you can connect to the fingerprint database of soldiers, including retired soldiers, and compare the fingerprints found at the scene, it is possible to directly get the name..."

"The fingerprint database is definitely no problem. However, did we find the fingerprints of the second murderer at the scene?" Qi Changye couldn't care about eating beef, although he was hungry and drooling into his stomach.

Jiang Yuan pointed to the bed sheet and said: "There should be a few here."

Qi Changye looked over and saw a piece of blood, but there was no sign of fingerprints.

"The murderer wiped his hands here first, and there is a string of dragged fingerprints, but he covered it with more blood later. Today's scene is fresh enough, we can uncover it here to confirm the fingerprints." Jiang Yuan did it while speaking, and soon really got the appearance of fingerprints.

Qi Changye was dumbfounded, and only woke up when Jiang Yuan asked him to link the database.

"Great, in this way, can we directly read the murderer's identity information?" Qi Changye's mood today can be described as ups and downs.

According to the analysis of previous situations, the more professional the opponent, the less information advantage his side can obtain.

And the work Jiang Yuan did obviously broke through this category. At present, it seems that Jiang Yuan is choosing which way to solve the problem more simply, rather than whether it can be done.

Jiang Yuan just nodded slightly and added: "This kind of fingerprint database may be relatively scattered. You can let them compare first to see if there are results."

Qi Changye continued to be dazed and nodded: "Good. Then we..."

"In such a good environment, let's do a crime scene reconstruction through bloodstain analysis." Jiang Yuan said, stepped back two steps, and opened the crime scene reconstruction (temporary +1 and lasted for 535 minutes).

Actually, it is not necessary at all. Such a fresh crime scene, there is blood, footprints are not few, and there are various traces of flipping, LV5 crime scene reconstruction is enough to beat.

However, from another angle, such a fresh scene, not using the temporary +1 skill of the crime scene is a waste.

This skill and the temporary +1 of any skill are independent of each other. If no one dies within the next 24 hours, it is really not used for nothing.

In this way, Jiang Yuan's crime scene reconstruction skill temporarily reached LV6, and Jiang Yuan's face sank slightly, slowly saying: "Acquaintance committing the crime. The murderer knocked on the door and entered, was intercepted by the victim at the porch, and the two likely had a dispute. The murderer forced the victim to enter the bedroom with violent means..."

"The victim basically had no ability to resist, indicating that the murderer's performance completely exceeded her expectations..."

"The murderer tortured the victim for a short time, the intensity was not low, and there should be gains. Judging from the order of searching for items, there is a strong purpose..."

Jiang Yuan completed the description work, sighed again, and said: "Actually, the back is useless. You should have a list of people related to the victim. Fingerprint comparison is good, the most stable way to get results..."

Qi Changye showed LV6-level shock, and the action of taking out the mobile phone only had LV0.2 stability. ===== CHAPTER 682 =====
