Mystery Tracker 2

Looking at the crumpled tissue, Cheng Jinsong felt a drop of cold sweat fall down his forehead, really afraid of something.When he was thinking about how to answer, Director Wang over there spoke first, and he smiled at Director Lu: "I said, old Lu, you are here to order Bai Gong to come to me?! Your branch office picked it up. If you don’t investigate the case yourself, what are you doing with me?!”

"Hey, I'm out of luck!" Director Lu replied with a smile, "The boys in our sub-bureau have been investigating for 4 days. Let alone suspects, they even found a little more clues. Such a piece of snot paper. So as soon as they heard that I was coming to the city bureau today, they hurriedly asked me to bring things over to ask you for help. In terms of technology, you are still very good here."

"Ju Lu," Cheng Jinsong finally found an opportunity, and explained: "As I said just now, our DNA bank currently only contains the DNA of 9% of the city's population, so even if we extract the DNA from your evidence, it will not be too late. It’s hard to find a match…”

"It doesn't matter, you do your best to investigate, to the extent that you can find out, at least provide some clues to those boys in our bureau."

Cheng Jinsong raised his eyes to look at Wang Ju, and seeing the latter nodded slightly, he didn't refuse again.He walked over and took the evidence bag: "Okay, I will check this evidence in a while, and I will send the report back to the branch office when I get the results."

Unexpectedly, Director Lu turned out to be impatient, and he waved his hands when he heard Cheng Jinsong's words: "No, you can do it now, didn't you say two hours? It just so happens that our meeting will last for about two hours, and the meeting is over. I'll come back and get the results."

? ! ...

Cheng Jinsong looked at Director Lu who was looking forward to it, and then looked at the other leaders beside him who were very interested. Knowing that this "quiz in class" could not be avoided, he had no choice but to nod in resignation...

Watching the leaders go down the stairs, Cheng Jinsong turned his head, looked at the evidence bag in his hand, and smiled wryly.The other team members looked at him with expressions that were half amused and half helpless.Xu Rou joked to Cheng Jinsong: "Brother Jin, it's not easy to earn 120 million?"

Cheng Jinsong glared at Xu Rou, raised his hand and threw the evidence bag to her, pretending to be angry and said: "Go! You do this job!"

"Yes Sir!" Xu Rou snapped a salute, then Cheng Jinsong stuck out his tongue mischievously, and walked towards the chemical laboratory with the evidence bag.

The chemical testing room is one of the earliest laboratories established by the forensic team, and it is also the busiest testing room on weekdays.At first glance, it looks like a university chemistry classroom. There are two rows of long tables in the center, and various experimental equipment are placed at the end of each table.There are several large cabinets standing on the east side of the room, in which there are large and small bottles and jars. All the test medicines stored at room temperature are stored here; those that need to be stored at low temperature are placed in the northeast corner. in the refrigerator.On the south side of the laboratory, there are all kinds of precision instruments for testing—such as the PCR machine that will be used now.

At this time, Xu Rou no longer had the mischievous look she had when she was joking with Cheng Jinsong just now. She was wearing a white coat, a mask and gloves, and she was completely working.She took out the tissue from the evidence bag, opened it carefully in front of the light, and immediately, a ball of booger appeared in the center of the tissue.Faced with this nauseating scene, Xu Rou didn't feel any discomfort at all. She professionally cut off the part that was stained with snot, and put it into a small test tube. Afterwards, she added deionized purified water and other related substances to it. Reagents, which are then placed in a centrifuge for shaking.Soon, the small piece of paper towel was beaten into a pulp-like suspension under the action of rapid rotation, which sank below the test tube; while above the test tube, there was a small section of clear solution.Xu Rou took out some supernatant with a pipette gun, and then put it into another test tube...

On the side, Cheng Jinsong watched Xu Rou's professional and stable operation, and nodded with confidence.

About one hour and three quarters of an hour later, Shen Hao, who was waiting for the results in the information technology processing room, saw the icons at the bottom of the screen flickering, and he sat up straight suddenly: "Miss Xiaorou's test results have arrived!"

The few people on the side immediately regained their spirits.

"Compare immediately!" Cheng Jinsong stood up and walked towards Shen Hao.

Shen Hao nodded, clicked on the comparison system and imported the data, and the server immediately started to operate.A group of people from the forensic team surrounded Shen Hao (including Xu Rou, who just rushed over from the next door), and everyone was staring at the big screen, waiting for the result with concern...

Speaking of which, the leaders didn't come here on a special trip today to embarrass the forensic team.Because today is July [-]st, the Municipal Bureau already had a commendation meeting for outstanding party members, which was planned a week ago.It's just that the forensic team just became famous at this juncture, so the leaders decided to stop by for a visit.However, the so-called leadership is to "do it" after "talking about it". No, after more than two hours, a series of big bosses represented by Director Lu came back to check and accept the results—and this time, not only He was accompanied by Wang Ju, and even Shen Yan was among them.

Director Lu is really impatient, and asked as soon as he walked into the office: "How about Xiao Cheng, did you find DNA on that thing?"

Cheng Jinsong and others waited in the office, and got up immediately when the leaders came back.Cheng Jinsong replied: "We found it. Although there is not much left, we still successfully extracted DNA from it."

"Really?! That's great!" Lu Ju's face showed joy, "Then did you find a match?"

Hearing this, Cheng Jinsong grinned, "As for Lu Ju, your case is really timely. If it had been a few days earlier, I might not have been able to solve the case." Seeing Lu Ju's puzzled expression , Cheng Jinsong pointed to the big screen: "We really did find a match from the system."

While speaking, the big screen in the information processing room began to change.The first two DNA comparison charts appeared, and the upper and lower DNA segments were completely consistent at each comparison point; then a photo of a middle-aged man appeared, and on the far right of the screen, an information sheet appeared .

"This man's name is Wang Yuquan," Cheng Jinsong introduced, pointing to the man on the screen. "Male, 36 years old, was arrested by the police two days ago for taking drugs and sent to a drug rehabilitation center. We checked the DNA records of drug addicts. He arrived. This record was just put into storage yesterday."

There was an instant burst of exclamation in the room.To be honest, the leaders didn’t react too much when they saw the demonstration of the witness team. After all, everyone knew that it was a demonstration that had been prepared in advance. It shouldn't be difficult.However, this is a real on-the-spot test, and the subject of this test is not a simulated case, but a difficult case that really happened and really stumped the police handling the case!However, the forensic team solved the case in just two hours without leaving home!This is really surprising.

When the leaders praised each other, Cheng Jinsong and the members of the forensic team stood aside, admiring the rare expressions of surprise and admiration of the leaders.Several people looked at each other, and everyone had a smug look on their faces.Of course, this is not the end, just when the voices of the leaders were getting quieter, Cheng Jinsong continued: "In addition, our police officer Shen Hao checked, and this Wang Yuquan has also been in other places in the south and east of the city. For similar behavior, we found his DNA in the evidence data of the three car smashing cases, so," Cheng Jinsong smiled and looked at the two chiefs of Chengdong District and Chengnan District, "These four cases should be solved together. .”

"boom"! ... There was another sound of admiration in the cabin.The eyes of the leaders of several sub-bureaus were almost shining, and some even asked Wang Ju and Cheng Jinsong about the price of this system on the spot.And when they knew that this system was not only expensive, but also took a long time to complete with the cooperation of multiple departments, they couldn't help admiring the courage and perseverance of the members of the Municipal Bureau and the forensic team.So several bureau chiefs looked at Bureau Wang, and said half jokingly and flatteringly: "I said Bureau Wang, from now on, we will send you here for any unsolved cases in our sub-bureau!"

"Everyone is in the same system, it's easy to talk and talk!..." Wang Ju also raised his face today, smiling like a Maitreya Buddha, with his mouth grinning so much that he could almost see his back molars.

Beside the directors, Shen Yan stood quietly, smiling as he watched Cheng Jinsong show off his demeanor again.Shen Yan was blocked by several leaders at the party meeting just now. When he heard that the leaders had actually arranged an impromptu task for the forensic team, Shen Yan was actually quite sweating for Cheng Jinsong.So when the leaders asked him if he wanted to come over to see the results, Shen Yan also came over.However, he did not expect Cheng Jinsong to perform so well.Shen Yan looked at his outstanding lover, a sense of pride and satisfaction rose in his heart.

Sensing Shen Yan's gaze, Cheng Jinsong turned around and blinked triumphantly at him.

The news that the forensic team made an extraordinary move in front of the boss group quickly spread throughout the police station.Soon, a group of guys who liked to join in the fun ran to the forensic team one after another, expressing piously that they would worship the "magic tool for solving crimes".Qin Kai, Cheng Haiyang and others even said boldly: "Brother Jin, with you, we don't have to go out and run around in the wind and sun! We will send the things from the crime scene to you. Then you use the machine to scan and immediately read out the murderer!!"

"You two just dream!" Cheng Jinsong gave them both a funny look, "I told you before that there are only more than 70 pieces of data in this system, which is less than 10% of the city's population. Lu It was a stroke of luck to find a match in the bureau’s case. You expect every case to be broken like this, unless you have the ability to get me the DNA of everyone in the city!”

What Qin Kai and Cheng Haiyang said was originally a joke rather than a serious one. Hearing Cheng Jinsong's explanation now, Qin Kai replied with a cheap smile: "Brother Jin, this task seems to be more involved...how about we check it out in the old way first?" ..."

Everyone in the room burst into laughter.

Jiang Ruiheng was also in the room. After everyone finished laughing, he smiled and said, "Actually, it is not necessarily so hopeless. With the current system of our country, those who can be entered into DNA by these databases are more or less people with some problems. , the probability that these people will be involved in the case is probably much higher than that of others, so in practice, I estimate that its effectiveness rate is much higher than 10%.”

This is quite reasonable, and Cheng Jinsong nodded in agreement: "We all hope so. So we should also pay attention to collecting DNA when handling cases in the future. The larger the capacity of this library, the greater help we can solve the case."

Jiang Ruiheng shook his right hand and nodded: "In the future, when I dissect the corpse, I will also record a copy of DNA for you."

Qin Kai watched Jiang Ruiheng's movement of holding his right hand, and asked with concern: "Speaking of Ruiheng, how is your hand? When will the stitches be removed?"

"The day after tomorrow." Jiang Ruiheng replied. Seeing everyone's concerned eyes, he smiled slightly, raised his right hand that was still wrapped in gauze, and said, "Don't worry, the doctor said that the operation was successful. After a period of rehabilitation, I can still afford the operation." knife."

Hearing what Jiang Ruiheng said, everyone nodded in relief.However, Cheng Jinsong on the side looked at Jiang Ruiheng with a slightly weaker smile than the others.He understands Ruiheng's temper. He seems to be free and unrestrained, but in fact he has a sense of proportion in his heart, and he never reports good news but not bad ones.Jiang Ruiheng's operation was relatively successful, but after all, the nerves and tendons in his hands are too dense, and the cut he was made at that time was really deep, so the doctor also said at the time that his hand would be able to recover to what condition it was, and he had to wait until it was removed. It will be clear after the line.Moreover, even if he can recover, he may have to go through a considerable period of rehabilitation in the middle.Jiang Ruiheng found Cheng Jinsong on the first day of work after the operation, and asked him to find a forensic doctor who would take his place temporarily. Although Cheng Jinsong knew this was normal, it inevitably made people worry about him.Cheng Jinsong once asked Li Jiayu about Jiang Ruiheng's situation, but Li Jiayu didn't know much about it, and Jiang Ruiheng didn't let Li Jiayu accompany him every time he had a follow-up visit to change his medicine.All of these made Cheng Jinsong feel less at ease.

When Cheng Jinsong was distracted, Jiang Ruiheng suddenly turned his head: "By the way, let me tell you, how is your forensic doctor doing?"

"Ah?" Cheng Jinsong was taken aback for a moment, and then he came back to his senses. He smiled wryly, and said, "Of course I'm still looking for it! These days your forensic doctors are a rare species. I've asked many places, but I can't find a single one. come."

"Although it's not easy to find someone like me with both intelligence and good looks," Jiang Ruiheng joked, and then his expression turned serious, "but you have to hurry up. Now I'm watching Xiao Wang slash, some little The case can still be dealt with. But if you really encounter some difficult corpses, I am afraid that Xiao Wang's current method is not good enough. You should hurry up, don't wait until the case comes out and catch you blind."

"I understand," Cheng Jinsong said, "I just hope that no case will happen recently, and give me two more days..."

However, Cheng Jinsong did not expect that his "crow's mouth" would come true again - because the next day, he and Shen Yan were called into the office by Wang Ju.And this time, this case is more scratching than ever before...

The author has something to say:

The small theater of this chapter:

Cheng Jinsong: Shen Yan, let's go to Fa and Lun Temple when we have time.

Shen Yan: Huh?Go to the temple, why?

Cheng Jinsong: Farewell to burning incense, lately it is always "crow's mouth" (＞﹏＜)

Shen Yan: -_-|||
