Chapter 26: Keep Up the Good Work

"Who matched it?" Jiang Yuan climbed up from the folding bed, drank some water, and washed his face with the water in the cup before feeling awake.

Wang Zhong laughed twice and said, "You were quite confident yesterday."

"They scrubbed first." Jiang Yuan answered very naturally. Scene investigation, those who do it first definitely have an advantage. If they do it carefully enough, maybe there will be nothing for those behind.

Furthermore, whether DNA can be scrubbed, and even if it is scrubbed, whether it can be detected, are all matters of probability.

When DNA technology first came out, criminals didn't understand it. Large pools of blood flowed at the scene, large lumps of semen fell on the ground, and large handfuls of hair remained on the bed, so the success rate was naturally high. Nowadays, purely stupid criminals are becoming fewer and fewer, and DNA, which relies on "trace amounts" for testing, is not so easy.

Furthermore, the testing in the DNA laboratory is also quite particular, and the technology in Ningtai County is far from reaching a reassuring level.

Wang Zhong smiled proudly: "Don't be humble, it was scrubbed by us."

Wu Jun looked at Wang Zhong: "Us?"

"I followed for a day yesterday... sigh, I'll just enjoy it for a sentence." Wang Zhong sighed heavily and said, "You don't know, the feeling yesterday and the feeling today are really different. Yesterday was like making up winter vacation homework for a day. Today is like the teacher strictly checking winter vacation homework, and it's the kind with huge rewards and punishments!"

Jiang Yuan was also quite refreshed, and, his refreshment was not only because of the match, but also because the newly acquired skill reflected its value. Thinking that there would be opportunities to acquire various skills in the future, he couldn't help but drink a large cup of water and then asked, "Which sample was it matched from? Does the suspect have a criminal record?"

DNA data is much less than fingerprint data. Matching directly in the database probably means there is a criminal record.

Wang Zhong didn't sell it anymore and said, "Because of picking quarrels and provoking trouble, he was caught once. The matched sample was taken from the brick seam of the wall in the bathroom. I think it should be the murderer."

"What is the relationship with the victim?" Wu Jun asked.

Wang Zhong said, "On the surface, there is no relationship, but this is where the problem lies."

"Hmm, no relationship, it's impossible to run into someone else's bathroom to take a bath." Wu Jun also tended to Wang Zhong's judgment. The bathroom was clearly cleaned and disinfected by the murderer. Most of the samples extracted before could not detect DNA. Now that one was finally detected after a hard re-examination, if it was a coincidence, Wu Jun would not believe it. Real cases don't have so many coincidences, instead, they are more likely to reveal flaws.

"The person hasn't been caught yet?" Jiang Yuan was a bit worried about the arrest problem.

Wang Zhong said, "Team Leader Liu is a veteran of arrest. As long as the murderer hasn't run away in advance, he can be caught back."

"He won't run. If he was willing to run, wouldn't so much concealment be wasted." Wu Jun guessed, but he was actually not grounded in this.

And within the Ningtai County Bureau, it was not just Wu Jun who was not grounded.

The most anxious one was Criminal Investigation Brigade Captain Huang Qiangmin.

On one hand, he expected good news from Team Leader Liu, and on the other hand, he was afraid that hope would fall through, and he had to urge police officers on other lines to continue working. He felt this way of doing things was split, but experience told him that any slack in the Golden 72 Hours was not allowed.

However, thinking from a good perspective, having major leads was a very good thing, much better than the anxiety of being a headless fly yesterday.

Huang Qiangmin couldn't sit still in the office, walked out of the door, walked from the first floor to the second floor, all the way to the fourth floor, and came to the forensic office.

The few people in the office were originally relaxed, but seeing Huang Qiangmin enter, their expressions tightened instantly.

"You do your work, I'm just looking around." Huang Qiangmin felt a bit awkward inexplicably, smiled in a pretentious way, and then naturally cared: "How is the work? Stayed up all night, tired?"

He didn't think much, but when he spoke, his smiles were all directed at Jiang Yuan.

"A bit tired, the folding bed is a bit small." Jiang Yuan said what he had to say. People with systems should always be willful.

Team Leader Huang was stunned. He had comforted the masses for so many years, and the answers he got were usually official answers like "not tired." However, thinking that Jiang Yuan had just joined the job and showed extraordinary abilities one after another, Team Leader Huang's smile rose again, and he said amiably: "They all say that young people today are different, sure enough, they speak differently from us old men. Hmm, you are tall, sleeping on such a small folding bed must be tired... I'll think of a way later..."

"I went to re-examine with Jiang Yuan yesterday..." Comrade Wang Zhong poked his head over.

The trace evidence examiners in the team were all familiar to Team Leader Huang. Therefore, Team Leader Huang looked at Wang Zhong with a soothing look, but the arc of his mouth split into the 33.3 degrees when facing cruel criminals, and said: "Good job."

Comrade Wang Zhong's heart tightened, the feeling was as if he were a vicious criminal who had been on the run for seventeen years before being caught.

"Why not live in the dormitory for a while? The dormitory in the bureau is relatively tight, I guess there is no way for a single room, I'll think of a way to vacate a bed, you can use it for lunch breaks..." When Team Leader Huang looked back at Jiang Yuan, his eyes were gentle, and the arc of his mouth was 66.6 degrees.

"Not needed for now." Jiang Yuan didn't quite understand the tightness of the beds in the police bureau, but he really didn't need it. The Jiang Village residential area was not very far, he was just too lazy to go home, not unable to go home.

Wang Zhong blinked his eyes in regret for a long time. His home was not in Ningtai County, but he had worked for so long and hadn't waited for the bureau's dormitory.

Wu Jun observed from the side, revealing a smile of understanding.

He had been in the county bureau for twenty or thirty years, and he understood the ecological model here too well. To summarize in one sentence, it is that the dry ones die of drought, and the flooded ones die of flooding.

Actually, it is also because the resources of the county bureau are limited, and talent resources are also limited. Because, in order to retain talent, they are willing to pay more resources than the prefecture-level city bureau, and in order to save this part of resources, there must be a lot of dry land.

Because he saw through this ecological environment, Wu Jun made a big fuss a few years ago, threatening to transfer, and asked the bureau leaders to solve his deputy section treatment. After all, compared to other positions, forensic medicine has quite high professionalism and rarity.

Calculated this way, Jiang Yuan's appearance could be considered a by-product of Wu Jun's previous big fuss.

Wu Jun was proud, and Team Leader Huang's phone rang.

Several people lowered their heads and pricked up their ears.

"Team Leader Huang, the person has been caught, we are going to identify the scene now." Team Leader Liu's voice came out, and anyone could hear the arrogance in it.

The situation at the scene, in theory, is only known to the murderer or eyewitnesses, so identifying the scene itself is excellent evidence.

"Did you find the murder weapon?" Huang Qiangmin asked for the first time.

Team Leader Liu hesitated for a while, his voice lowered, and said: "This kid confessed, saying he threw it into the Tai River."

"I am applying to the higher authorities now. After you identify the scene, go to confirm the location of the murder weapon and organize personnel to salvage it." Huang Qiangmin didn't consider the cost problem at all this time. The Tai River is wide, the water is shallow, and the impact is not great. Metal objects falling into it have a certain probability of being salvaged. The police force has experience in this regard.

Team Leader Liu agreed immediately and said in a low voice: "We also found some burned ashes in his house. This guy washed the bloody clothes and brought them back, and then burned them. I asked him why he didn't throw them into the river directly? He was worried that there would be his DNA on the clothes, and if they were thrown together with the murder weapon, he was afraid that they would be turned over by others in a few years and convicted..."

"So cautious?"

"He's a scholar." Team Leader Liu curled his lips on the other end of the phone, "His heart is bad, he thinks a lot, his psychological quality is extremely poor. After we found his door, he was incoherent. Team Leader Huang, this case is taken down."

"Hmm, well done!" Huang Qiangmin encouraged, and after exhorting, he hung up the phone.

Turning his head, Huang Qiangmin looked at Jiang Yuan again, his mouth split into a 66.6-degree smile, and said: "Take advantage of the free time, rest well. You can go back early today."

Seeing Wang Zhong poking his head again, Huang Qiangmin added: "Jiang Yuan, go home and sleep well. Young people should try not to overdraw their bodies. Others... we are all old comrades, keep up the good work, strive to solidify the case today! Nail the murderer!" ===== CHAPTER 27 =====
