Chapter 23 Special gameplay
noon.

After washing and sleeping at home for a while, Jiang Yuan immediately rushed back to the criminal police brigade.

Entering the courtyard, you can feel the dignified atmosphere.

Several of the two bar ones and two bar two at home were all frowning and whispering in a heavy voice.When passing by, the footsteps were in a hurry, and there was exhaustion in the eyes.

Police ranks are different from military ranks. The white shirt and below are basically not linked to leadership positions. Including the chief of the county bureau, police ranks represent seniority.

However, for ordinary policemen, high seniority often means the status of the main force.

For a serious case like a murder case, if it is handed over to young people with a bar, no one has any idea.

Jiang Yuan himself is a young man with a bar and a bar, and he doesn't even know the dogs in the police station well. The criminal policeman who talks the most may be the captain Huang Qiangmin.

Wu Jun hadn't come back yet, and Jiang Yuan didn't want to go back to the office to feel the pressure, so he turned his head and went straight to the police dog squadron.

Da Zhuang, a police dog who had also been busy all day, was lying in front of the nest, his ears drooping lower than usual.

Li Li was busy in the kitchen with her back on her back. Through the kitchen window, the kitchen door, and the reflected sunlight, she could see her beautiful back, elegant movements, and amazing slender waist and long legs.

"Jiang Yuan?" Li Li turned around after all, her face like Ronaldo instantly broke all the previous impressions.

"Woof." The real Ronaway Dazhuang also called out.

"Da Zhuang, sit down." Li Li waved her hand, then asked Jiang Yuan, "Did you stay up late yesterday?"

Jiang Yuandao: "I slept for an hour in the morning. I didn't want to eat in the cafeteria. I wanted to come over and make fried rice with eggs."

Li Li smiled, her thick eyebrows visibly twitched, and said, "It's just right, make me one too. I can't even make dog food. Just now I was thinking about burning an extra chicken leg... ..."

The big and strong eyeballs of the police dog turned to Li Li's direction, and after a while, they turned back again.

"I'll cook the rice." Jiang Yuan said, rolling up his sleeves and getting started.

Uncle Seventeen's fried rice not only saves ingredients, but also is quick to make, like a night market king.

Jiang Yuan quickly cooked a pot of fried rice, and made a pot of tea with the teapot in the kitchen.

The skill of making tea comes from the legacy of Xue Ming from Xinde. However, as part of the camping skills, the tea brewed is really lackluster.

"Wait a minute, the dog rice will be ready soon. There is too much meat and it won't be cooked well." Li Li explained.

Jiang Yuan put the fried rice on the table, took another sip of tea, and said, "Can you pet the dog?"

"It's possible to be bitten. If you're not afraid, just masturbate." Li Li rolled up her sleeves, half to scare Jiang Yuan.

Just looking at the arms and not the face, Li Li's arms are actually quite beautiful, a bit like a dancer, white and shiny, slender and muscular, which makes the scars on them quite conspicuous, but if you look closely, The appearance of the injury is not too deep, and it is quite attractive, which makes the man want to be the second strong a few times...

Jiang Yuan judged the depth of the scar with forensic experience, felt relieved, and said, "Then I'll touch a few."

With that said, Jiang Yuan stood beside Da Zhuang, eager to try.

Seeing this, Li Li had no choice but to shout: "Da Zhuang, touch me."

The big and strong ears dropped instantly, the body stretched out, and the tail slowly swayed.

Jiang Yuan's hand immediately covered Da Zhuang's forehead, and with a little effort, he closed his eyes comfortably.

There is a saying: Luo Nawei, a bald dog, feels oily, rubs slippery, although the hair is thick, it looks light, and the teeth are white.

"Trained, it feels different." Jiang Yuan praised.Although this dog is as fierce as a fire, when it is gentle, it is like a licking dog. Its bald head arches and sticks out its tongue from time to time, which is really cute.

"It's time to eat." Li Li came out with a big bowl of dog rice in both hands.

Different from usual, today's dog meal has added a lot of beef, each piece is the size of a walnut, which is an affirmation of the police dog's work yesterday.In addition, the ratio of chicken and vegetables is also quite a lot, and there are piles of them that stand out, and there is a feeling that the meal cost exceeds the standard.

"I'm going to serve fried rice." Jiang Yuan consciously brought out fried rice with an average cost of 0.8 yuan per person, and poured a cup of tea for each of them. They ate the yellow-orange fried rice and drank the tea, gobbling it up.

Next to him, Luo Nawei ate his meal bit by bit.Looking at it like that, he neither enjoys it nor is he willing to give it up, just like a licking dog who has paid a lot or resisted but was finally tamed.

Jiang Yuan looked pitifully, and said to Li Li: "I cooked a lot of rice today, give some to Da Zhuang? I just used oil and eggs, and there are very few seasonings..."

"You can't give it to me, and you can't give the fried rice to the dog." Li Li took away Jiang Yuan's extra fried rice without disdain, and it was delicious.

Jiang Yuan could only touch Da Zhuang's head, then finished his own, got up and went back to the office.

Wu Jun had already arrived, rubbing his eyes, squatting in front of an electric stove, gurgling and cooking something.

He is also getting older, and he is very tired if he stays up late on duty, and it is even more uncomfortable to stay up late for an autopsy.

"Jiang Yuan is here." Wu Jun greeted him.

"I went to the police dog squadron to cook a meal, have you eaten yet?" Jiang Yuan asked.

"It's a bit puffed up, I don't want to eat it. My stomach feels uncomfortable." Wu Jun waved his hands and said, "Don't mess with the others, eat a red egg."

Blowing, he scooped up an egg with the skin dyed red with a spoon, put it on the table, and beckoned Jiang Yuan to take it.

Jiang Yuan asked without any surprise: "What's the point?"

"When you see a dead person, eat a red egg to avoid evil. It's nothing special." Wu Jun scooped up a red egg for himself, cracked it open and let it stand on the table.

When the egg was cooler, Jiang Yuan also cracked the egg, peeled it slowly, and ate it.

The taste of ordinary boiled eggs, just left a bunch of red eggshells.

"In the past, if there were corpses on the scene, the cafeteria would cook red eggs." Wu Jun said while eating the eggs.

"Why is it gone now?"

"There are too many deaths, and the cafeteria is troublesome." Wu Jun said: "Now there are fewer homicides and more abnormal deaths. If you don't move, you will be a high fall, and if you don't move, you will drink pesticides."

Wu Jun ate the red eggs in two or three bites, and said again: "Hurry up and sort out the information, I'm busy today. If you can't find any clues, you won't be able to sleep at night."

"Okay." Jiang Yuan's mood became heavier.

The criminal police brigade, which is under the pressure of solving the case, is under the most uncomfortable pressure at this time.

There is a saying of 72 golden hours in the murder case.It is said that the 3 days from the occurrence of the case to the detection of the case are the most important, and it is also the time with the greatest chance of solving the murder case.

There is also a considerable scientific basis for this.

On the one hand, the shorter the time, the more traces and physical evidence of crimes are preserved, and the easier it is to discover the relevance of various clues and cases.Including eyewitnesses and insiders of the case, their memory rules are also clearest and most accurate within 72 hours, and then decay extremely.

On the other hand, during the first three days after the incident, the criminals had the most activities and were the most vulnerable psychologically.

Regardless of whether or not there is preparation before committing the crime, and how well the preparation is, after the actual crime is committed, the criminal's psychology will be greatly affected in the first three days. Considering the possible consequences of the crime, the criminal may cover up or hide. Maybe when asking questions, there will be a lot of contact with the outside world, and it is also the time when it is most likely to be caught. After this period of time, the criminal's mood and psychology gradually stabilize, and the hiding place is determined, etc. Even if the person is identified, arrest and interrogation will encounter difficulties.

In addition, the fatigue value of the policeman in charge of the case will also continue to accumulate over time.

In today's environment, the pressure to solve murder cases is under pressure.The police directly involved in the investigation of the case basically stayed up all night.After persisting in this way for two or three days, the fatigue is basically exhausted.

If the person can be caught within three days, then the police officers who participated in the war can grit their teeth and continue to interrogate them.But if you can't catch someone and let it go in one breath, it will definitely take double the time to make up for it.

For the new homicides in Ningtai County, 24 hours have passed without any new clues. This is definitely a disturbing trend.

"The hair DNA was sent out for an investigation, and the results were not very good." Wang Zhong got the news the first time, and quietly ran to the forensic office.

Both Jiang Yuan and Wu Jun looked over.

Wang Zhong said in a low voice: "The DNA laboratory in the provincial capital won the comparison. But there is an alibi. The other party works in a KTV and was dealt with by the security brigade. The time of the incident happened to be out of town to accompany the guests."

"How could there be pubic hair left in the victim's crotch when he was accompanying guests in other places?" Jiang Yuan thought for a while and asked a key question.

Wang Zhong laughed, and said in a low voice: "The victim who accompanied me in the morning took 500 yuan. Then I drove to the provincial capital. I also got the photo from the traffic police. There are witnesses beside her..."

"There is so much evidence of alibi?" Wu Jun was a little curious: "She is going to deliver food, why is she bringing witnesses with her?"

"Two people, 2000 per person." Wang Zhong stretched out two fingers.

Wu Jun clicked his tongue: "County towns are different from provincial capitals. Their value has skyrocketed to four times."

"Special gameplay also requires additional money." Wang Zhong corrected.

Wu Jun shook his head: "People's hearts are not old, I am now partnering with Xiao Jiang, and every time we go out, we are two together, and the salary will not increase by a dime."

Wang Zhong couldn't keep up anymore, he looked back at Jiang Yuan stiffly, and said: "The investigation of the unit and the place of residence has no results, and the fingerprints and traces have not found a match. The old residential area where the deceased lived, the nearby monitoring There are not many, and the video has not been found to be useful, and the relatives have not finished the investigation, but it is estimated that it has no effect..."

"What about now?" Jiang Yuan's focus is still on the case. This is the second murder case he has experienced, and he still has a strong sense of participation.

Wang Zhong was silent for a while, and said: "I heard that the current investigation direction is still based on the deceased's interpersonal relationship, and the final result is hard to say... However, if there is no result by tonight, the overall situation should be mobilized. "

The Ningtai County Public Security Bureau does not have any so-called detectives, or Niu Honghong's masters in solving crimes.In the face of cases, the means used are all conventional means.If there is any big killer, it is the crowd tactics.

In a big city, even if a murder case is discovered and it is difficult to solve it for a while, at most it is to form a special case team and second some personnel, dozens or hundreds of people will be enough.But in small counties, homicides are discovered. When necessary, it is normal for thousands of people to investigate—not to investigate thousands of people, but to dispatch thousands of staff to conduct investigations. If necessary, they can give A college guy does DNA.

At this time, not to mention the criminal police brigade, everyone from the police station to the government officials will be dispatched, and some police stations will even borrow people from other units.

Jiang Yuan frowned slightly.

Doing investigations is the basic labor force, and he has LV4 crime scene investigation, which may be the strongest investigation in the county, so he should choose a direction that is more likely to lead to clues.

"Let's do a re-survey." Jiang Yuan offered.

Repeated investigations are a matter of course for current investigators, and it is also a basic requirement for forensic doctors to re-investigate on-site.

Jiang Yuan recalled the operations of the previous surveyors, and he already had a plan in mind.

The surveyors who belonged to the Criminal Squadron were at an average level in terms of technology and dedication. Jiang Yuan looked at the LV4 level of crime scene investigation, and he could always find the omissions.

Although I don't know if there are clues in these places, Jiang Yuan's sense of responsibility unconsciously swelled when the investigation of the case was at a standstill.
