Nie Chaofan woke up after squinting for two hours. He stumbled and had a dream. In the dream, the girl who was killed by a woman was sitting on the ground, holding his right foot and shouting for help.
"Help me...wuwu...help me..."
"Police uncle...save me...I don't want to die..."
With a choked voice, he slowly raised his little head.
A pair of empty, pupil-less eyes looked straight at me!
"call..."
Nie Chaofan sat on the bed, his sheets and underwear soaked with sweat. He touched his chest and felt that his heartbeat had not completely calmed down and his breathing was a little short.
After a while, Nie Chaofan wiped the cold sweat from his forehead, took a few deep breaths, and got up.
Nie Chaofan calmed down, his face was calm, and his movements of slowly dressing were calm and powerful. He had once again become the most senior police officer in the Criminal Investigation Brigade.
Even though Nie Chaofan understands in his heart that although he has worked in criminal investigation for twenty years and the medals he has earned can be used as bulletproof vests on his chest, most of the cases he has led over the years have been kidnapping, extortion, guns and explosions, and organized crime.
.
There are murder cases, but the few we encounter are crimes of passion where the evidence can hit your face. Like this time, there are no clues in the case, and none of them have been touched.
But after staying in the Criminal University for so many years, the group of people who knew his background were leaving and mentioning him. The young people who stayed behind or the leaders who were transferred from other units only knew that he was the most senior police officer in the entire brigade.
This time he volunteered to be transferred to the Serious Crime Squadron.
The case was naturally initiated by him.
This is the good thing he dreams of.
But last night, the autopsy took a long time, and a bunch of forensic doctors gathered together, but they couldn't find any semen in the girl's penis.
It's been going on for a long time. Could it be that the murderer is impotent and can only be obscene?
Nie Chaofan walked to the general office on the second floor with a sullen face and saw that it was so lively that no one had slept.
He really didn't sleep either.
This situation is indeed normal.
The first 72 hours after a murder is discovered are the most precious time. This is the opinion given by experts. This is correct, but not completely correct. For example, in the early years when communications were not developed, one of the tasks after the crime was to visit nearby local residents.
The short-term memory of residents is only seventy-two hours at most, so if you visit again after three days, even witnesses may miss key clues, let alone other details.
But the most important point is still the investigation of the police. After a murder occurs, the police basically fight continuously, and the limit of a person's persistence is 72 hours. No one can bear it when they are dizzy. But as long as they relax, this person
I'm just too lazy to hold on. So a case that couldn't be solved in the first three days will probably take several times, or more than ten times, the next time, and the result may still be that it still can't be solved.
"Have you found the person?" Nie Chaofan asked as soon as he entered the door.
"Detective Nie, this is the autopsy report given by Lao Cao. No semen was found in the girl's vagina, but the DNA from the fingernails has been extracted and sent to the city's laboratory. It is estimated that it will take half a day to produce the map. The identity of the deceased
I found it..." As soon as the police officer in question replied, he saw a group of people pouring over from the office next door.
"Detective Nie!" There was a pony in the crowd. Seeing Nie Chaofan, he quickly ran over to report, "The truck carrying Wang Xia was found in the surveillance! The owner was also found, his name is Zhao Zhiguo! He's a man!"
If the DNA in the girl's fingernails matches that of Zhao Zhiguo, the case will be solved. Not to mention, this science and technology is really good... Nie Chaofan's worries are finally relieved.
The earliest use of DNA technology to solve crimes in China was in the late 1980s, but it was not common. The technology was really promoted to the grassroots for handling cases around 2002. The construction of grassroots DNA laboratories was also at this point in time.
It was gradually rolled out. As for the DNA bank, it was only officially opened to case-handling units around 2011. The most effective one at the moment is the Y bank. The more famous ones are the Baiyin case and the Nanyang Medical case, which were solved through the Y bank.
Nie Chaofan thought about it and warned: "To be on the safe side, even if Zhao Zhiguo has been located, the visit to the crime scene cannot be missed, let alone delayed. Well, we will go to the scene again after breakfast later. By the way,
You should get an application form as soon as possible and take it to the technical investigation department to export the whereabouts of Zhao Zhiguo."
"The application form has been prepared. We will send it to you as soon as work hours arrive in the morning!" Xiao Ma patted his chest confidently, "Tan Nie, don't worry, I have done all the work that needs to be done."
"Yeah, that's good. By the way, are Wang Xia and Zhao Zhiguo from the same village? Are they relatives or friends?" Nie Chaofan also wanted to confirm his judgment.
"I checked and found that they are all in the same village. Since they can follow me on the bus and travel such a long distance across the province, I must know them all!" Xiao Ma said in detail, with an excited tone.
Nie Chaofan nodded: "The focus of the next work is to arrest people! Arrest this person named Zhao Zhiguo!"
Among all rape cases involving women, typical rapes in which the perpetrator and the victim are completely unknown to each other account for only 8% of the total. Excluding the 2% who are unwilling to disclose, the remaining 90% are all related to the two parties.
Basic acquaintance rape.
Nie Chaofan took the thick stack of files in Xiao Ma's hand, weighed the weight, and then said: "Xiao Ma, you go have breakfast. I'll scan the files first. By the way, I'll go to the technical detective immediately after breakfast.
Pull the material on the side.”
Xiao Ma agreed immediately and said as he walked: "Understood! Detective Nie, you have to take me with you when arresting people this time!"
Young people know how to arrest people, but they don't know that the early stage of investigation is the most grueling work... Nie Chaofan shook his head helplessly, carrying the file and walked to his office seat.
Although this case was easy to solve, due to the wanton fermentation of the media, the current social influence is rushing towards the Public Security Bureau like a storm.
For Nie Chaofan, the organizer, this is a good thing.
The greater the social impact of a case, the greater the help it will give him after solving the case.
Why do the police pick cases to handle? Firstly, the police force is indeed limited, and there is no way to achieve results in every case. Secondly, the police will sort the cases in their hands, which cases should be handled first and which cases should be handled later.
exquisite.
The case is assigned by the leader, has a bad social impact, is difficult to detect, etc. But no matter what, the case still needs to be handled, and no criminal police officer will be lazy and ignore the case in front of him.
Thinking of this, the eyes of this tough guy who had been in the industry for twenty years and dared to fight with gunmen with bare hands turned red, showing a rare look of cowardice.
In recent times, his wife's attitude towards him has become more and more intense, and turning a blind eye when he comes home occasionally is considered a minor offense. During a rare phone call, in addition to the accusation of "not being at home every day" and the abuse of "abandoning his wife", Nie Chaofan can't do anything about it.
Argument.
Nie Chaofan, who is over 40 years old, has never tried to put down his job. Since then, his parents have grown older and his children have become more sensible. He has thought for a long time whether he should retire from his current position. Anyway, at his current age, he is transferred
The criminal police station is not considered a deserter.
However, he still had some anger in his heart.
"Snapped!"
Nie Chaofan slammed the table and gritted his teeth and said: "One last try! This case is solved, let's go regardless of whether we can get the job or not!"
The eyes that were originally dim began to brighten up little by little.
