Chapter 26 Make persistent efforts
"Who is better?" Jiang Yuan got up from the camp bed, took a sip of water, took the glass of water with his hand, and washed his face before he felt more awake.

Wang Zhong laughed twice and said, "It seems that you were quite confident yesterday."

"They wiped it first." Jiang Yuan replied very naturally.For on-site investigation, it is definitely an advantage to do it first. If you do it carefully enough, maybe there will be no one behind you.

Furthermore, whether the DNA can be wiped, or even detected, is a matter of probability.

When the DNA technology first came out, criminals didn't understand that the blood of the big beach was flowing on the scene, the big lumps of semen fell on the ground, and a lot of hair was left on the bed, so the success rate was naturally high.Nowadays, there are fewer and fewer criminals who are purely stupid, and it is not so easy to rely on "trace amounts" of DNA for testing.

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

Wang Zhong smiled proudly: "Don't be modest, we wiped it out."

Wu Jun looked at Wang Zhong: "We?"

"I was with you all day yesterday... Oh, I'm just happy." Wang Zhong said with a heavy sigh, "You don't know, the feeling yesterday is really different from today's feeling. Yesterday is like using a day's work. Time to make up for the winter vacation homework. Today is like the kind where the teacher strictly checks the winter vacation homework, and the rewards and punishments are huge!"

Jiang Yuan is also very cool, and his cool is not only because he won the competition, but also because the newly acquired skills reflect the value.Thinking about the opportunity to acquire various skills in the future, I couldn't help but drink a glass of water, and then asked: "Where did the test materials be collected? The suspect has a criminal record?"

The data of DNA is much less than that of fingerprints, and the comparison can be done directly in the library, which means that there is a high probability that it has a criminal record.

Wang Zhong didn't hold back anymore, and said: "I was arrested once for picking quarrels and provoking trouble. The material for the comparison was taken from the brick crack in the wall next to the toilet. I think it should be the murderer."

"What's the relationship with the victim?" Wu Jun asked.

Wang Zhongdao: "On the surface, it doesn't matter, but this is the problem."

"Well, it's okay, it's impossible to take a bath in someone else's bathroom." Wu Jun also leaned towards Wang Zhong's judgment.The bathroom was obviously cleaned and disinfected by the murderer. Most of the samples extracted before could not detect DNA. Now the re-inspection finally found one. If it is a coincidence, Wu Jun does not believe it.There are not so many coincidences in real cases, but flaws are more likely to be exposed.

"He hasn't been caught yet?" Jiang Yuan was a little worried about the arrest.

Wang Zhongdao: "Captain Liu is an experienced arrester. As long as the murderer doesn't escape early, he can be arrested."

"I won't run away. If you are willing to run, so many concealments are not in vain." Wu Jun's guess is guesswork, but he is actually not convinced about it.

But within the Ningtai County Bureau, Wu Jun was not the only one who did not fail.

The most worrying one is Huang Qiangmin, the captain of the criminal police team.

On the one hand, he expected good news from Captain Liu. On the other hand, he was afraid that his hopes would fail, so he had to urge other policemen with various clues to continue working. This approach made him feel divided, but his experience Tell him that any slack within 72 hours of gold is not allowed.

However, on the bright side, it is always a great thing to have important clues, and it is much better than yesterday's anxiety like a headless chicken.

Huang Qiangmin couldn't sit still in the office anymore, so he went out for a stroll, from the first floor to the second floor, all the way to the fourth floor, and came to the forensic office.

Several people in the office looked relaxed at first, but when they saw Huang Qiangmin coming in, their expressions suddenly tightened.

"You guys do it, I just take a look." Huang Qiangmin was inexplicably embarrassed, pretended to smile, and then asked naturally concerned: "How is work? Are you tired after staying up all night?"

He didn't think much about it, but when he spoke, his smile was directed at Jiang Yuan.

"A little tired, the camp bed is a little small." Jiang Yuan said something.People with a system must be willful after all.

Captain Huang was stunned for a while. He has been condolences to the masses for so many years, and the answers he gets are usually official answers such as "not tired". Unknowingly got up again, and said kindly: "It is said that young people are different now, and it is true that they speak differently from us old men. Well, you are also tall, and you must be tired sleeping on such a small camp bed... I will think about it later. Method……"

"Yesterday, I went to re-survey with Jiang Yuan..." Comrade Wang Zhong poked his head over.

There were only two traces in the team, and Captain Huang was familiar with them. Therefore, Captain Huang smiled at Wang Zhong with soothing eyes. When the criminal was 33.3 degrees, he said: "Good job."

Comrade Wang Zhong's heart twitched violently, as if he was a villain who had just been arrested after 17 years of exile.

"No, I can't live in the dormitory for a while. The dormitory in the bureau is quite tight. I guess there is no way to do it in a single room. I will find a way to make a bed. You can use it for lunch breaks..." When Team Huang looked back at Jiang Yuan, The eyes are gentle, and the curvature of the corners of the mouth is also 66.6 degrees.

"Not for now." Jiang Yuan didn't quite understand the tension of the beds in the police station, but he really didn't need them either.The Jiangcun community wasn't very far away either. He was too lazy to go home, not unable to go home.

Wang Zhong blinked his eyes regretfully for a long time.His family is not from Ningtai County, but he has been working for so long, and he didn't even get a dormitory in the bureau.

Wu Jun watched from the side, showing a smile of understanding.

He has stayed in the county bureau for 30 to [-] years, and he understands the ecological model in front of him very well. In one sentence, it is drought, drought, and waterlogging.

In fact, the resources of the county bureau are also limited, and the human resources are also limited.Because, in order to retain talents, they are willing to pay more resources than prefectural and municipal bureaus, and in order to save this part of resources, it is inevitable to have a lot of dry land.

It is precisely because of seeing through this ecological environment that Wu Jun made a big fuss a few years ago, threatening to transfer him away, and demanded that the bureau leader give him the sub-department treatment.After all, compared with other positions, forensic medicine has a high degree of professionalism and rarity.

Calculated in this way, Jiang Yuan's appearance is a by-product of Wu Jun's previous disturbance.

While Wu Jun was proud, Captain Huang's phone rang.

Several people all lowered their heads and pricked up their ears.

"Captain Huang, we've been caught. Let's go and identify the scene now." Captain Liu's voice came out, and everyone could hear the arrogance.

Theoretically, only the murderer or witnesses know the scene, so identifying the scene is excellent evidence in itself.

"Have you found the murder weapon?" Huang Qiangmin asked immediately.

Captain Liu hesitated for a moment, then lowered his voice, and said, "This boy confessed that he threw it into the Taihe River."

"I'm applying to my superiors 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 issue at all at this time.Taihe River has a wide surface, shallow water depth, and low impact force. If metal objects fall into it, there is a certain probability of salvage. The police force has experience in this area.

Captain Liu responded 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 just throw them into the river?" He was worried that there would be his own DNA on his clothes, and he would throw it away with the murder weapon, fearing that someone would find it again in a few years and be convicted..."

"So cautious?"

"Student." Captain Liu curled his lips on the other end of the phone and said, "He has a bad heart, thinks too much, and has a very poor mental quality. After being approached by us, he didn't make any sense. Captain Huang, this case is settled." gone."

"Well, good job!" Huang Qiangmin encouraged him, and after giving instructions, he hung up the phone.

Looking back, Huang Qiangmin looked at Jiang Yuan again, with a 66.6-degree smile on the corner of his mouth, and said, "Take a good rest while you are free. You can go back early today."

Seeing Wang Zhong poking his head again, Huang Qiangmin added: "Jiang Yuan goes home and sleeps well, and young people try not to overextend their health. Everyone else... we are all old comrades. Let's make persistent efforts and strive to solidify the case today." ! Nail the murderer!"
