Chapter 550: A Detective in His Forties

Early morning, six o'clock.

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, woo, help me."

"Uncle policeman, help 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 him!

"call"

Nie Chaofan sat on the bed, sweat soaking his sheets and underwear. 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 knew in his heart that although he had worked in criminal investigation for twenty years and the medals he had earned could be used as bulletproof vests on his chest, most of the cases he had led over the years were 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 and no case, and none of them have been touched upon.

But after staying in the Criminal University for so many years, the group of people who knew his background were constantly moving and carrying 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 was the good thing he had dreamed 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.

After doing it 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. He saw that it was so lively that no one had slept.

And indeed I didn’t sleep.

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 entirely correct. For example, in the early years when communications were not yet developed, one of the tasks after the incident was to visit nearby residents. Human short-term memory only lasts for seventy-two hours at most, so if you visit again three days later, even witnesses may miss key clues, let alone other details.

But the most important point lies with the investigating police officers. After a murder occurs, the police basically fight continuously, and the limit that a person can endure is 72 hours. No one can bear it when they are dizzy. But as soon as he relaxes, this person will become lazy and unable to hold back. Therefore, a case that cannot 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 cannot 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 It's been found." 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 of the truck 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 has finally let go of his worries.

The earliest use of DNA technology to solve crimes in China was in the late 1980s, but it was not common. It was around 2002 that this technology was actually promoted to the grassroots level for case handling. The construction of grassroots DNA laboratories was also gradually launched at this point in time. 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 library. The more famous cases are the Baiyin case and the Nanyi case, which were solved through the Y library.

Nie Chaofan thought about it and warned: "To be on the safe side, even if Zhao Zhiguo has been located, the platoon visit to the crime scene cannot be skipped, let alone delayed. Well, we will go to the scene again after breakfast later. By the way, Please 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 each other in the car and travel such a long distance across the province, they must all know each other!" Xiao Ma said in detail, with an excited tone.

Nie Chaofan nodded: "The next focus of our 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 this time!"

Young people only know how to arrest people, but they don't know that the preliminary investigation is the most tiring work. Nie Chaofan shook his head helplessly, carrying the file and walked to his office seat.

Although this case is easy to solve, due to the wanton fermentation of the media, the current social influence is surging towards the Public Security Bureau like a storm.

For Nie Chaofan, the host, this is a good thing.

The greater the social impact of the case, the greater the help to him after the case is solved.

Why do police pick cases to handle? First, the police force is indeed limited, and it is impossible to achieve results in every case; second, the police will sort the cases in their hands, and there are rules for which cases to handle first and which cases to handle later.

Assigned by the leader, those with bad social impact, and the difficulty of detection, etc. But no matter what, the case still needs to be handled, and no criminal police will be lazy and ignore the case in front of them.

Thinking of this, the eyes of this tough guy who had been in the industry for 20 years and dared to fight with armed gangsters with bare hands turned red, and he rarely showed a cowardly look.

Recently, his wife's attitude towards him has become more and more intense. Occasionally, she turned a blind eye to him when she came home. When they rarely talked on the phone, she would be accused of "staying away from home every day" and cursed for "abandoning his wife", but Nie Chaofan had no way to refute this.

Nie Chaofan, who was over 40, had tried to give up his job. Since then, his parents have grown older and his children have gradually become sensible. He thought for a long time whether he should retire from his current position. Anyway, at his current age, he would not be considered a deserter if he was transferred from the criminal police post.

However, he still had a grudge in his heart.

"Bang!"

Nie Chaofan slammed the table and gritted his teeth and said, "One last fight! If this case is solved, I will leave regardless of whether I can be promoted or not!"

The eyes that had been dimmed began to brighten up little by little.
