"The car will be here soon. Stop directly at the gate of the community. Captain Jiang, you can go downstairs." Qi Changye's mouth was dry and his voice was hoarse as he spoke.

He was quite excited, but he held up his cell phone for too long, talked too much, and used his brain for too long. Plus, he had been staying up for several days, and he couldn't hold it any longer.

At this time, a slightly unfamiliar yet familiar voice came from Jiang Yuan: "Bring some meat to your colleagues. I put the seasoning bag next to it. In fact, it's fine without dipping it in the seasoning. The meat we cooked can be eaten with ease." It all smells good.”

"Okay. Then bring two boxes. They are quite hungry." Jiang Yuan took the big box brought by Jiang Fuzhen.

The box was specially customized in the early years. It is very convenient for giving as gifts or bringing your own. There is meat inside, and there are simple places for bowls, chopsticks and seasonings. You can open it to eat when you go out for camping or the like.

Jiang Fuzhen then asked the chefs to quickly pack another box of beef, and think about it with another box of steamed buns, pickles and the like. As the saying goes, meat should be paired with carbohydrates, even if it is given to a county magistrate, it is just right for the level of cadres in the capital.

Qi Changye held up his mobile phone, listened to the words on the other side, and whispered in a very embarrassed voice: "Captain Jiang, there is no need to bring it with you. We are on site again, and we cannot eat on site..."

"Whoever eats on site, you ask him to come to the laboratory to look at the microscope." Jiang Yuan first responded, and then said: "You can eat outside the cordon, it is best to find an indoor place. At the same time, repair your gloves. Change the hoods and everything else, and put on new ones when you enter the scene again..."

Without waiting for Qi Changye's response, Jiang Yuan picked up his things, ended the call, and called out Mu Zhiyang, Wang Chuanxing and others, making a total of six people.

The No. 2 murderer he was facing now was the one who could escape from Qi Changye and his professional colleagues. Jiang Yuan didn't want to explore how professional he was at all.

But when 6 professionally trained police officers gathered together and did not use thermal weapons, the defense was still no problem.

…

Plum Grove Garden.

A police car with traffic police motorcycles clearing the way arrived at the crime scene in just 20 minutes.

Jiang Yuan thanked him and hurried upstairs.

Now is the time to race against time. Before traces such as pools of blood solidify, the time can be judged by minutes. But once solidified, because we don’t know when it completely solidified, the time of death can be judged by at least one moment. The clock is wrong.

Fingerprints, DNA, or other biological materials, including trace evidence, certainly have the advantage of being long-lasting, but the fresher the better.

Those ancient fingerprints may require LV3 fingerprint experts to compare, while the fresh ones may be handled by Wang Zhong.

What is more likely is that some of the inspection materials have either deteriorated or been decomposed by organisms over time, and the on-site survey personnel cannot see them at all, let alone their quality.

"I brought you beef." Jiang Yuan handed Qi Changye the meat box given by his father at the door of the residence where the crime occurred.

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

"Just send a few people to pull up the security net to prevent murderer No. 2 from leaving and returning." Jiang Yuan said seriously.

Qi Changye was stunned: "Normally not."

"Safety first." Jiang Yuan said, dressed neatly, and began to investigate inside.

Mu Zhiyang followed, and said to Qi Changye in passing: "Eat some meat and rest. It's time to send someone. Don't follow. You're too tired."

Qi Changye was also exhausted. When Mu Zhiyang tapped him, he suddenly woke up and said, "I will send, I will send..."

As he spoke, Qi Changye stretched his neck again and whispered: "Captain Jiang, we found the image of murderer No. 2 in the nearby surveillance, but we lost him after chasing him."

"Is there an image of the murderer? Show it to me?" Jiang Yuan then explained: "If there is a video recording, the murderer's gait and posture can be determined, which will be helpful for footprint analysis and blood stain analysis."

Qi Changye hurriedly agreed and came back with a notebook in a short while.

"The main thing is these few videos." The first thing Qi Changye released was a video from a surveillance camera near the building. He could clearly see the physical characteristics and body shape of the second murderer, but his face was obscured by a mask and sunglasses. Unrecognizable.

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

Qi Changye felt that he had been praised and chuckled twice. Suddenly he realized something was wrong and said hurriedly: "It's not much better. The main reason is that the requirements in the capital are high. When choosing, the needs are different... This case is also urgent. We first searched for cameras with higher resolution.”

"Theoretically, we can use skull reconstruction technology to restore the facial features of the second murderer, but this will take several days..." The first half of Jiang Yuan's sentence almost lit up Qi Changye's eyes, and the second half made him His eyes became erratic.

Qi Changye whispered: "Actually... it can be done in a few days. Although this case is urgent, it is not urgent here..."

Jiang Yuan waved his hand, interrupted Qi Changye's words, and transitioned to the second monitoring, and said: "Look at the murderer's gait, the soldier's temperament is still there, he should be in a state of long-term and continuous movement. If you can connect to the soldier , including the fingerprint database of veterans. Compare the fingerprints found at the scene, and it is possible to directly reveal the name..."

"There must be nothing wrong with the fingerprint library, but have we found the fingerprints of murderer No. 2 at the scene?" Qi Changye no longer cared about eating beef, although his hungry saliva went straight to his stomach.

Jiang Yuan pointed to the sheets and said, "You should be able to get a few here."

Qi Changye looked over and saw a patch of blood, but there were no fingerprints.

"The murderer wiped his hands here first, and there was a string of fingerprints dragged out, but he then covered it up with more blood. Our scene today is fresh enough, and we can uncover it to confirm the fingerprints. "Jiang Yuan said as he did it, and soon he really got the fingerprints.

Qi Changye was stunned. It was not until Jiang Yuan asked him to connect to the database that he woke up from a dream.

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

Based on the analysis of past situations, the more professional the opponent we encounter, the less information advantage we can obtain.

The work done by Jiang Yuan has obviously broken through this category. At present, it seems that Jiang Yuan is more like choosing which method can solve the problem more easily, rather than whether it can be done.

Jiang Yuan just nodded slightly, and then said: "This kind of fingerprint database may be fragmented. You can ask them to compare it first to see if there are any results."

Qi Changye continued to be confused and continued to nod: "Okay. Then let's..."

"In such a good environment, let's do a crime scene reconstruction through blood stain analysis first." Jiang Yuan said, taking two steps back and opening the crime scene reconstruction (temporary +1 and lasting for 535 minutes).

In fact, there is absolutely no need. In such a fresh crime scene, there is a lot of blood, a lot of footprints, and various signs of turning. The LV5 crime scene reconstruction is completely sufficient.

However, from another perspective, it would be a waste not to use the temporary +1 skill of the crime scene in such a fresh scene.

This skill and any skill's temporary +1 are independent of each other. If no one dies in the last 24 hours, it will really be useless.

As a result, Jiang Yuan's crime scene reconstruction skill temporarily reached LV6. Jiang Yuan's face turned gloomy and he said slowly: "An acquaintance committed the crime. The murderer knocked on the door and entered, but was intercepted by the victim at the entrance. The two of them were likely to have an affair. After a dispute, the murderer used violent means to force the victim into the bedroom..."

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

"The murderer tortured the victim for a short time and the intensity was not low. He should have gained something. Judging from the order of rummaging through the items, he had a strong purpose..."

Jiang Yuan finished the description, sighed again, and said: "Actually, the rest is of no use anymore. You should have a list of the victims' contacts. Fingerprint comparison is done, the most stable way to get results... "

Qi Changye showed shock at level 6, and when he took out his mobile phone, he only had the stability of 2.
