Chapter 26: Keep up the Good Work

"Who won the competition?" Jiang Yuan climbed up from the cot, took a sip of water, took the cup of water with his hand, and washed his face before feeling more awake.

Wang Zhong laughed twice and said, "I see you were quite confident yesterday."

"They wiped it first." Jiang Yuan answered naturally. When it comes to on-site investigation, there is definitely an advantage in doing it first. If you do it carefully enough, you might not have anything to worry about for the people behind you.

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

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

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

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

Wu Jun looked at Wang Zhong: "We?"

"I followed you all day yesterday... Oh, I just feel good." Wang Zhong sighed heavily and said, "You don't know, yesterday's feeling is really different from today's feeling. Yesterday was like a day's work I have time to catch up on my winter vacation homework. Today is like the kind where the teacher strictly checks the winter vacation homework and gives huge rewards and punishments!"

Jiang Yuan was also very happy, and he was happy not only because he won the competition, but also because the newly acquired skills showed 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 was the test material collected in the competition? Does the suspect have a criminal record?"

The DNA data is much less than the fingerprint data. If you compare it directly in the library, there is a high probability that you have a criminal record.

Wang Zhong stopped talking and said: "I was arrested once for picking quarrels and provoking trouble. The test materials in the competition were taken from the cracks in the brick wall of the bathroom toilet. I think he must 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 doesn't matter. It's impossible to take a shower in someone else's bathroom." Wu Jun also tended to Wang Zhong's judgment. The bathroom had obviously been cleaned and disinfected by the murderer. Most of the previously extracted test materials could not detect DNA. Now a re-examination finally found one. If it was a coincidence, Wu Jun did not believe it. There are not so many coincidences in real cases, but flaws are more likely to be revealed.

"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 caught."

"I won't run. If you are willing to run, all the cover-ups will not be in vain." Wu Jun's guess was just a guess, and he was actually not sure about it.

Within the Ningtai County Bureau, Wu Jun is not the only one who is not at ease.

The most worrying person is undoubtedly the criminal police captain Huang Qiangmin.

On the one hand, he expected good news from Captain Liu, but on the other hand, he was afraid that his hopes would be dashed, and he had to urge other police officers with clues to continue working. This approach felt divisive to him, but his experience Tell him that any relaxation within the golden 72 hours is not allowed.

However, thinking on the bright side, it is always a good thing to have major clues, which is much better than the anxiety like a headless fly yesterday.

Huang Qiangmin couldn't sit still in the office, so he went out for a walk without hesitation, walking from the first floor to the second floor, all the way to the fourth floor, and arrived at 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 your thing, I'm just watching." Huang Qiangmin felt a little embarrassed for no reason, pretending to smile, and then asked with natural concern: "How is your 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 bit tired, the camp bed is a bit small." Jiang Yuan said something. Systematic people are always more willful.

Captain Huang was stunned. He had been consoling the masses for so many years, and the answers he got were usually official answers such as "not tired". However, when he thought of Jiang Yuancai's entry into the job, he showed his outstanding abilities one after another. Captain Huang's smile Unconsciously, he got up again and said amiably: "They say that young people today are different. They really talk differently to us old men. Well, you are also tall. It must be tiring to sleep on such a small camp bed... I will think about it later. Method……"

"I went to review the survey with Jiang Yuan yesterday..." Comrade Wang Zhong poked his head over.

There were only two trace inspectors in the team, and Captain Huang was familiar with them. Therefore, Captain Huang smiled at Wang Zhong with comforting eyes, and the cracked corners of his mouth unconsciously evoked the feeling of facing cruelty. The third degree of the criminal, and said: "Well done."

Comrade Wang Zhong's heart suddenly tightened. He felt as if he was a murderer who had just been captured after seventeen years of exile.

"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 use a single room. I'll find a way to free up a bed. You can use it for your usual lunch break..." When Captain Huang looked back at Jiang Yuan, The eyes are gentle, and the curvature of the corners of the mouth is also 6 degrees.

"No need for the moment." Jiang Yuan didn't quite understand how tight the beds were in the police station, but he certainly didn't need them. Jiangcun Community is not very far away. He is too lazy to go home, not unable to go home.

Wang Zhong blinked sadly for a long time. His family is not from Ningtai County, but he has been working for so long and has not even been able to find a dormitory in the bureau.

Wu Jun observed from the side, showing an understanding smile.

He has been in the county bureau for 20 to 30 years, and he understands the ecological pattern in front of him very well. To sum it up in one sentence, drought will cause death, and waterlogging will cause death.

In fact, the resources of the county bureau are limited, and the human resources are also limited. Because, in order to retain talents, they are willing to spend more resources than the prefecture and city bureaus, and in order to save these resources, a large amount of dry land will inevitably be needed.

Precisely because he saw through this ecological environment, Wu Jun made a big fuss a few years ago, threatening to be transferred away and asking the bureau leaders to give him a treatment as a deputy department. After all, compared to other positions, forensic medicine is quite professional and rare.

Calculated this way, Jiang Yuan's appearance can be regarded as a by-product of Wu Jun's previous commotion.

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

In theory, only the murderer or witnesses know the situation at 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 guy confessed that he threw it into the Taihe River."

"I am now applying to my superiors. After you identify the scene, you will confirm the location of the murder weapon and organize personnel to salvage it." Huang Qiangmin did not consider the cost issue at all at this time. The Taihe River is wide, the water depth is shallow, and the impact is not great. If metal objects fall in, there is a certain probability that they can be salvaged. The police force still has experience in this area.

Captain Liu immediately responded and whispered: "We also found some burned ashes in his house. This guy washed the bloody clothes and brought them back and burned them. I asked him why he didn't just throw them into the river? He is worried that if his DNA is on his clothes and thrown together with the murder weapon, he is afraid that someone will find out in a few years and he will be convicted..."

"So cautious?"

"You're a scholar." 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 psychological quality. After we came to the door, he started to talk incoherently. Captain Huang, we have taken this case. ”

"Well, good job!" Huang Qiangmin encouraged him and gave some instructions before hanging up the phone.

Looking back, Huang Qiangmin looked at Jiang Yuan again, with a 6-degree smile on his lips, and said: "Take a good rest while you have free time. You can go back early today."

Seeing that Wang Zhong was probing his head again, Huang Qiangmin added: "Jiang Yuan goes home and has a good sleep. Young people should also try not to overextend themselves. Others... we are all old comrades. We will continue to work hard and solidify the case today." ! Nail the murderer!"
