Chapter 176: Investigation
The water in Taihe River flows continuously.
Riding a bicycle across the bridge will make you feel refreshed.
Jiang Yuan likes Ningtai in autumn very much. Everything is lush and lush, and the height of the river is just right. The floating corpses that occasionally float down are mainly accidental deaths and natural disasters, which do not always remind people of the despicability and desolation of human beings.
In the courtyard of the criminal police team, there are also smiling faces filled with enthusiasm. Especially the man who looks after the parking lot feels happy every time he receives a cigarette from Jiang Yuan.
Huang Qiangmin happened to be walking downstairs, and when he saw Jiang Yuan, he looked even more excited than Da Zhuang.
"You're willing to come back." Huang Qiangmin wanted to grab Jiang Yuan's head to see if he had been used badly. The main reason is that Jiang Yuan is too tall, which is really uncomfortable.
Jiang Yuan laughed twice and said: "We happened to encounter a corpse burning case... We don't know when it will happen in Ningtai County, so I just want to see it."
"Our simple folk customs in Ningtai County have turned into a mistake?" Huang Qiangmin said angrily: "Serious cases are the criterion that reflects the level of public security in a place. This month, the number of thefts in our county has almost been reduced to zero. You don't need it. Practice techniques for corpse burning.”
Jiang Yuan frowned: "Is there still a theft case?"
"There are always people who pick up sheep. They don't pick up things on the road and don't close their doors at night. That was the era of bird raw fish soup."
"This is the era of cameras." Jiang Yuan defended, and then said: "The surveillance is still not very reasonable."
Surveillance cameras are not just about filming this thing, they also need to form a complete system.
A typical example is tracking a criminal suspect. If there are breakpoints at every turn and you have to rely on the dog to raise its head from time to time to detect, the efficiency will be too low.
In addition, the quality of the camera, the supporting software of the surveillance system, and the configuration of the image detection technicians are all linked together.
Ningtai County is currently barely using it, and it still depends on the weather and luck to catch people.
It's also the thieves in the county who don't want to make progress or pursue progress. Otherwise, if they try to get in a few times, they can easily find out the blind spots of surveillance. When the time comes, they can steal things and those who should sing and dance can sing and dance. How could he be reduced to a part-time job?
Huang Qiangmin would not continue talking about surveillance.
This kind of project is large in volume, lasts for a long time, and has huge subsequent maintenance costs. It is simply not something that he, the criminal police captain, can decide.
He didn't want to decide such a thing either.
Huang Qiangmin just smiled, pulled Jiang Yuan, and said as he walked: "You have never been in the police station. People nowadays don't dare to kill people and are very motivated to make trouble. I hope there will be fewer criminal cases. Go around Pat Heung and get more fireworks.”
Jiang Yuan was young and could not understand Huang Qiangmin, so he also smiled.
Huang Qiangmin saw that the big animal was full of energy and seemed to have no use for it, so he immediately said: "If there is no current case, you can just go through the backlog. It's just time to go through the debts of our Ningtai County."
If the family has no land, they can only open up wasteland.
This is also what Huang Qiangmin is looking forward to most. There is only so much existing output, and it is beneficial to open up wasteland.
"Let me give it a try." Jiang Yuandao.
"If you want to watch it, watch the murder case." Huang Qiangmin emphasized a little. Handling a case requires expenses for handling the case, but if it involves a murder case, it is understandable that there will be some overspending.
"I'll look back." Jiang Yuan showed a little bit of confidence.
Not to mention, he now has a variety of skills that can be coordinated with each other. In the past, he could crack the provincial and department supervision cases brought by Liu Jinghui just by looking at the files. He can indeed use them to show off.
Jiang Yuan thought about it in his mind, and returned to the office on the fourth floor, smiling and smoking all the way.
Medical Examiner's Office.
The floor was swept clean and water was sprinkled.
Wu Jun crossed his legs, hummed a tune and smoked while filling out the appraisal report.
Seeing Jiang Yuan come in, Wu Jun first smiled, then rolled his eyes and dropped his pen...
"Master, Team Huang is going to let me get some backlogs to take a look at." Jiang Yuan handed out a Chinese stick and placed the remaining half bag on the master's table.
Wu Jun took Zhonghua habitually, then sighed and said, "Okay. We don't have much daily work to begin with... By the way, you did a murder case this time?"
"right."
"Then I have to say goodbye." Wu Jun babbled, gesturing to Jiang Yuan to do it himself.
Jiang Yuan hesitated for a moment, then stood up and closed the door, took out a statue of Guan Yu from the drawer at the bottom of his desk, bowed three times seriously, ordered a Chinese stick, and placed it in front of Second Master Guan.
Wu Jun felt a little distressed inexplicably, and he couldn't help but stand up and said: "Second Master Guan, I have been a donor for many years, and he usually smokes my cigarettes."
He took out a box of white cloud smoke from the drawer, lit it respectfully for Mr. Guan, and took back the burned Zhonghua.
He himself usually smokes Yunyan, but the price he smokes is 23 yuan a pack. The white box of pearlescent white Yunyan is priced at 5.5 yuan, which is getting harder and harder to buy, but 20 pieces are enough for Mr. Guan to use for a year.
Looking back, Wu Jun saw that Jiang Yuan's expression was as usual, so he lit another pearly white, gently put it on the ground, and said to Jiang Yuan: "Let's jump into the fire to get rid of bad luck."
The butt of the cigarette that had just been lit was glowing red, burning slowly and steadily.
Jiang Yuandi stepped over the lit clouds and smoke, stepped back, and then stepped over again.
At the end of the ceremony, the two of them returned to their seats.
Jiang Yuan turned on the computer and Wu Jun picked up the pen.
The years are quiet.
The internet speed is extremely fast.
Jiang Yuan dug up old unsolved cases in Ningtai County, searched aimlessly for a while, and then began to look for crime scenes with a large amount of blood stains.
Among the various skills Jiang Yuan has mastered, LV5 Dog Rice and LV5 Bloodstain Analysis are his strongest weapons.
That is to say, there are fewer violent crimes now. If it were 20 years ago, Jiang Yuan would be so busy that he would die.
The number of homicides in Ningtai County has been declining year by year.
This is the case in most counties in the country.
On the one hand, this is due to the cliff-like decline in contact violent crime, and on the other hand, the decline in young people.
In the final analysis, young people today are different.
Go forward ten years, and the annual homicide rate in Ningtai County will double, and even further forward.
Jiang Yuan was famous for his work, and a murder case from 13 years ago was brought up.
The case occurred in the earliest "high-rise building" in Ningtai County. A female body was found on the rooftop of a 22-story tower-style residence. The deceased was a 16-year-old girl who disappeared a day ago.
Jiang Yuan chose this case because there was a lot of blood on the scene.
From the rooftop where the body was found, to the fire door on the rooftop, to the stairwell, there were splatters and pours of blood, and there were also a large number of bloody footprints at the scene.
But no fingerprints or blood stains of the murderer were found.
When the technical route could not be opened, the task force also conducted a large number of investigations and visits, but no important clues were found.
Jiang Yuan clicked on the photos and looked through them one by one.
For this kind of case, bloodstain analysis and crime scene reconstruction is a very good solution, provided that the photos taken at the scene are suitable.
