Chapter: 45

Jiang Yuan is still in the novice excitement period. He has just obtained the crime scene investigation LV4 skill, and the scene he has actually investigated is the one in front of him. Naturally, try and practice to your heart's content.

Among the currently surveyed skills, skill is of course very important, and meticulousness is essential. On the other hand, physical strength, energy and concentration are the keys to a higher level. It's as if Xue Huaiyi fell out of favor with Wu Zetian, because his experience and skills have improved, but is he disgusted instead? Obviously not. In the same way, the Zhang brothers will not fall out of favor because they are young and reckless and impulsive.

Of the above, what Wang Zhong lacked was not one or two. However, although he was a little tired, he was driven by Jiang Yuan and tried his best to support him.

Jiang Yuan especially wiped the ceiling and corners of the bathroom carefully.

As time went on, he became more careful and confident in his actions.

This house does not have dry and wet separation, but the bathroom area is small. When taking a shower, the probability of water splashing on the wall and ceiling is not low, and it is impossible to clean it thoroughly in a short time. The only problem is whether the DNA can be wiped. The bloodstains were probably washed away or destroyed, but this person is probably an amateur in washing away all traces of DNA.

Ordinary people, unplanned killings, normally don't learn related skills in advance. Even if you learn, you don't necessarily have to work hard, and you don't necessarily have to be proficient in learning, so there is a high probability of being picked up by the police who are hardworking, serious and proficient.

into the night.

Jiang Yuan and Wang Zhong dragged their bags back to the police station and went straight to the DNA laboratory.

Nowadays, there are more and more cases where DNA is used to directly solve crimes, and the investment of the police station in DNA laboratories is also increasing. Even Ningtai, a poor county, has built a DNA laboratory under the guidance of various subsidies and policies and in accordance with the standards given by the ministries and commissions.

This is also the gold-swallowing beast unit of the police station, a laboratory of three people in total, devouring more than 10% of the police station's funds every year, and it will increase from time to time.

However, unlike Wang Zhong's expectations, the DNA laboratory just silently accepted the piles of physical evidence bags and did not raise any objections.

They didn't even carefully examine and criticize the biological samples sent by Jiang Yuan and Wang Zhong.

"The old money from DNA, why has it become easier to talk about?" Wang Zhong followed Jiang Yuan directly to the forensic office, and began to mutter.

In the forensic office, Wu Jun didn't go home either. Like most criminal police officers, he sat in the office and sorted out the materials he had made during the day. Standing up and rubbing his eyes, Wu Jun said slowly, "In the afternoon, the captain still lost his temper. The problem now is that there is no clue. The DNA laboratory is eager for you to send over the test materials so that you don't have nothing to do."

Jiang Yuan was delighted to hear it: "Does it count as having nothing to do if you don't work at night?"

"The captain didn't go home." Wu Jun said: "If they can't find anything, they will go to re-examine themselves."

Wang Zhong looked at Jiang Yuan, clicked his tongue twice, and said, "It's useless for them to go. As far as their current level of investigation is concerned, I'm not saying that ordinary cases are fine..."

Wu Jun interrupted Wang Zhong: "Do you think they don't know?"

"Uh..." Wang Zhong was speechless and went back to his office silently.

Jiang Yuan was quite satisfied, he tidied up and spread out the camp bed in the office.

Until the noise, the policemen who had been staying up all night started to quarrel.

"One person was found in the DNA comparison, and Team Liu took him there." Wang Zhong was the first to rush into the office, with secretions still hanging from the corners of his eyes.

"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."
