"Who won the competition?" Jiang Yuan climbed up from the cot, drank some 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 very naturally. There is definitely an advantage in doing the on-site inspection first. If it is done carefully enough, the people behind may not have anything to worry about.
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. Now.
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 modest, 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
It’s time to catch up on winter vacation homework. Today is like the teacher’s strict inspection of winter vacation homework, and the rewards and punishments are huge!”
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 opportunities he would have to acquire various skills in the future, he couldn't help but drink a glass of water, and then asked
Said: "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, and if it is directly stored in the library, it will most likely mean that the person has 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 maybe this is the problem."
"Well, it doesn't matter. It's impossible to take a shower in someone else's bathroom." Wu Jun also leaned towards Wang Zhong's judgment. The bathroom had obviously been cleaned and disinfected by the murderer, and most of the previously extracted test materials could not detect DNA.
Now the re-examination has finally found one. If it is a coincidence, Wu Jun does not believe it. Real cases do not have so many coincidences, but it is easier to expose flaws.
"He hasn't been caught yet?" Jiang Yuan was a little worried about the arrest.
Wang Zhongdao: "Captain Liu is a veteran in arresting people. As long as the murderer doesn't escape early, he can catch him."
"You can't run. If you are willing to run, all the cover-ups are not 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 the bottom.
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 disappointed, so 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 yesterday's headless anxiety.
Huang Qiangmin couldn't sit still in the office, so he went out for a walk, 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 are doing your job, I'm just taking a look." 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 late?"
He didn't think much about it, but when he spoke, his smile was directed at Jiang Yuan.
"I'm a little tired, and the camp bed is a little small." Jiang Yuan said something. People who have a system 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 nowadays 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 a soothing look, and the cracked corners of his mouth unconsciously evoked the feeling of facing cruelty.
The criminal's 33.3 degrees, 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's no way to use a single room. I'll try to find a way to free up a bed for you to use for lunch breaks and so on..." When Captain Huang looked back at Jiang Yuan,
Her eyes are gentle and the curvature of her mouth is 66.6 degrees.
"No need for the time being." Jiang Yuan didn't quite understand the shortage of beds in the police station, but he really didn't need them. Jiangcun Community was not very far away. He was too lazy to go home, not unable to go home.
Wang Zhong blinked in regret for a long time. His family was not from Ningtai County, but he had been working for so long and never got 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 lead to drought, and waterlogging will lead to death.
In fact, county bureaus have limited resources, and talent resources are also limited. Because, in order to retain talents, they are willing to spend more resources than prefecture and city bureaus, and in order to save these resources, a large amount of dry land is inevitable.
It is precisely because he has seen through this ecological environment that Wu Jun made a big fuss a few years ago, threatening to be transferred and asking the bureau leaders to provide him with the treatment of deputy departments. After all, compared with other positions, forensic medicine is both more professional and rarer.
It's quite high.
Calculated this way, Jiang Yuan's appearance can be regarded as a by-product of Wu Jun's previous commotion.
When 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.
Theoretically, only the murderer or eyewitnesses know the situation at the scene, so identifying the scene itself is excellent evidence.
"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 an object falls in, there is a certain probability that it can be salvaged. The police force 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.
Already."
"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 66.6-degree smile on his lips, and said: "Take a good rest while you are free. You can go back early today."
Seeing that Wang Zhong was probing again, Huang Qiangmin added: "Jiang Yuan goes home and has a good sleep. Young people should also try not to overwork their bodies. Others...we are all old comrades. We will keep up our efforts and strive to solidify the case today."
