New policeman: Take a gift money and run into a bank robbery?

Chapter 68 There are many doubts, what is the special significance of this?

"Anyway, there is the murderer's bodily fluid, put it in the system and compare it, and the result will come out, why hasn't the case been solved yet..."

In the corner, a young detective muttered.

"Do you think the murderer did not leave DNA information in the case back then? With the update of the database, we will take out the DNA for comparison almost every year, but we still find nothing. The murderer's information has never entered the police system."

An old police officer shook his head and said, "You are still too young, the murderer is a pervert with extremely strong self-control."

Back then, based on the information left by the murderer and the brutal methods, criminal investigation experts constructed a portrait of him.

The murderer is an adult man, about 1.7 meters tall, most likely a native of Lu City, most likely suffered from women's blows, withdrawn, pessimistic about the future, interested in women's bodies, and extremely hates them. ..

The two people in the audience were whispering, and Jian Zhenguo on the stage had asked the police to start reporting the social relationship of the deceased.

"The deceased, Du Yulian, female, 22 years old, was the only daughter of the Du family, and is now an employee of the power company. She left home at 11:25 pm on November 01 to go to work at the company, and left the unit at 30:04. Snacks and computers left on.

At 05:30, her father came to see her, but he heard that she went to the movies, so he didn't care. Du Yulian's social relationship is simple, and she is very popular in the unit. There is no chance of enmity. One of them is in love My boyfriend is Peng Yongxin, who works in the radiology department of the county hospital.

According to Du Yulian's parents, the two had a quarrel a few days ago, and Peng Yongxin hasn't come home to look for Du Yulian for a few days..."

After listening to the police investigation, Jian Zhenguo pondered for a while, then looked at Lu Sheng: "Lu Sheng, what do you think?"

Lu Sheng glanced at Jian Zhenguo's earnest expression, and unceremoniously analyzed: "There are still unfinished work and unpacked snacks on Du Yulian's desk, and 04:30 is not the off-duty time of the power company, which means she is Being called out temporarily does not rule out the possibility of acquaintances committing crimes."

"You can visit her colleagues in the company, who called her out at the time, and check the victim's call records..."

Lu Sheng talked eloquently, these are the basic ideas for solving the case, they are so common, so Jian Zhenguo can naturally think of them.

"However, I have a little doubt. Du Yulian graduated from a technical secondary school, so she shouldn't meet the employment standards of the power company?"

"Her parents let her in because of their relationship. Everyone in the company knows this."

The policeman said quickly.

Lu Sheng nodded, this is normal.

In a human society, relationships are sometimes more important than abilities.

"Li Wei, bring a few people to visit Du Yulian's boyfriend, and pay attention to ask the reason for the conflict between them..."

"Assign a group of people to investigate all the surveillance at the location of the incident, and closely observe the people who appeared nearby from 04:30 to 06:30 in the afternoon."

"A group of people, visit the school of the deceased Du Yulian to see if Du Yulian has any enemies or suitors."

"..."

Orders were issued one after another, and most of the criminal police team members were dispatched quickly and scattered into every corner of Rong'an County.

"Captain Jian, I want to go to the archives to see if I can find any valuable clues!" Seeing that he hadn't been assigned a task, Lu Sheng volunteered.

Now that the murderer has reappeared, maybe there are some details that have been overlooked in the past, and the answer may be found in the file.

"it is good!"

Jian Zhenguo readily agreed, he knew that Lu Sheng had always had a clear mind, and maybe he could give him an unexpected surprise elsewhere.

......

The first case happened on September 2003, 09. The deceased was named Yao Xinting, 12 years old. Her head was cut off and a crescent moon was engraved on her forehead. There was no sign of being violated...

The second case happened in March 2004. The deceased was Ye Xinxin, 3 years old, an employee of a company, but he had already landed at the National Examination and Taxation Bureau, and there was no trace of violation...

The third case occurred in June 2004...

August 2004.....

...

On October 2005, 10, the deceased Yu Yushan, female, was a middle school teacher in Shui'an County, and there were traces of being violated before her death...

Lu Shengyou noticed that the murderer committed crimes before 2005 and did not violate the victim, and the time interval between the first crime and the second crime was the largest.

According to the autopsy report in the dossier, the No. 1 victim's neck was chopped off with a boning knife or something, and the murderer showed a little familiarity with the human body, so he should have learned some medical knowledge by himself.

From the second one onwards, the murderer's hands became more and more agile, and the wound was smoothed out, almost killing him with a knife.

Lu Sheng was a little puzzled, and really wanted to chop off the person's head.

It's not as easy as the performance in TV dramas. It requires not only strong physical strength, but also an extremely sharp blade.

There are very few people who meet these two conditions at the same time.

With the ability of the police at the time, it was easy to find out, but after investigation, it was found that these suspects all had alibi.

"Why did the murderer leave a crescent moon mark on the forehead of the deceased? Is there any special meaning?"

Lu Sheng couldn't understand it.

These victims are all in their 20s, of similar age, and have no social relationship with each other.

There are also differences in beauty, ugliness, fat and thinness, and the murderer committed the violation only in 2005. Why didn't the murderer commit any violations before?

There are too many mysteries, like a bunch of messy threads, the more you reason, the more chaotic.

With a bucket of instant noodles, Lu Sheng forcibly sat in the file room for a whole day.

At this time, the police officers who were visiting outside also came back one by one.

"Jian team, according to our interviews, we found that at the time of the crime, the boyfriend of the deceased Du Yulian, Peng Yongxin, was on duty in the hospital duty room. The colleagues in the hospital also confirmed this to us, and we can basically rule out his suspicion of committing the crime.

However, he provided us with an important clue. Du Yulian once pursued a boy when she was in school, and Du Yulian's parents also found many letters about the two when they sorted out the relics..."

Naturally timid

Jian Zhenguo took a stack of thick letters from Li Wei's hand and looked through them carefully.

"Or women chasing men?"

Most of the letters were returned, signed by Du Yulian, the letters were stalking, only one was sent by a boy named Li Yu.

The content is roughly 'it's impossible for the two of them, don't pester him anymore' and so on.

The policeman next to him was also very strange.

As the saying goes, men chase women across mountains, and women chase men with separate layers of yarn.

I have never seen a girl chasing a boy and stalking her to death without success.

"Has this Li Yu investigated?"

After Jian Zhenguo briefly read all the letters, he suddenly realized: "Du Yulian and her boyfriend quarreled because of this, right?"

Li Wei nodded, and took a sip of water in the gap: "I exchanged opinions with my colleagues who went to the school to investigate, and found that the emotional entanglement between them is indeed a bit complicated..."

After a pause, seeing that everyone was looking at him, he said: "According to Du Yulian's roommate, Du Yulian has been pursuing this boy named Li Yu during her school days.

Li Yu has never been interested in her, but Du Yulian also has a suitor, which is her current boyfriend Peng Yongxin. Seeing that the pursuit was fruitless, Du Yulian agreed to be Peng Yongxin's girlfriend. Alibi..."

Lu Sheng was a little speechless when he heard it. Simply put, this was a love-hate entanglement between licking a dog and licking a dog.

"After hearing about Du Yulian's death, what was her roommate's reaction?"

Lu Sheng asked suddenly.

"Because their school has a 3+2 school system, there are four people in the dormitory, and the other two have gone out for internships. We only met one of the roommates, and the others were interviewed by phone, but their reactions were flat, saying that they didn't have much contact with Du Yulian. .”

"I heard other students say that the roommate at school has a good relationship with Du Yulian. I often see the two of them in pairs, going to the cafeteria to eat together..."

But this is nothing unusual, there are friends who seem to be close to each other, and many people are afraid of getting into trouble.

Du Yulian's social relationship is very simple, and her conduct is good. The police can't find any clues at all. Could it be that the real murderer behind the blood moon case has reappeared?

Lu Sheng was also puzzled.

The case has reached an impasse.

At this moment, the police officer in charge of the body fluid test from the technical department got the results.

"The DNA sequence extracted from the body fluid was successfully matched in the system!"

Jian Zhenguo looked overjoyed immediately, grabbed the inspection report from the police officer, and looked at it carefully.

"Xie Qin?"

"Yes! That's Xie Qin." The police officer pointed to the photo file handed over: "This guy is a frequent visitor to the detention center, and he is a famous bastard here..."

"Where is this man now?"

"He works in an electronics factory in our Rong'an County Industrial Park."

Although it felt a little bit wrong, Jian Zhenguo was naturally overjoyed when he finally got a clue to the case.

"Then what are you waiting for? Bring a few people and come with me!"

.......

The arrest process went smoothly. With the cooperation of the factory leaders, the police easily entered the dormitory building.

When they arrived at dormitory 301, everyone in the room was sound asleep.

When the icy bracelet was cuffed on Xie Qin's wrist, Xie Qin woke him up immediately.

"You...you...what are you doing? I've been a law-abiding citizen these days!"

Originally, he wanted to swear, but when he saw the room full of people, he swallowed the obscenities that came out of his mouth immediately.

Don't dare to provoke, there are too many people.

"Abiding by the law?"

Li Wei sneered, and roughly dragged him off the bed, "Be honest! What's your name?"

"Xie Xun!"

Seeing Li Wei's vicious attitude, Xie Qin felt annoyed immediately, rolled his eyes and blurted out lies.

Anyway, he hasn't broken any law recently, so he's afraid of a ball!

Xie Xun?

Li Wei was taken aback, did he catch the wrong person?Look at the factory leaders who are following...

"Xie Xun? Why aren't you called Zhang Wuji?" Lu Sheng took a step forward and shouted sharply.

"Yes, my name is Zhang..."

Xie Qin wanted to make jokes, but with Shang Lusheng's majestic eyes, he couldn't say anything else.

"My name is... Xie Qin."

"We are from the County Criminal Police Brigade, do you know why we arrested you?"

Hearing that it was the Criminal Police Brigade, Xie Qin was even more frightened.

Usually he just does some petty theft, and the people he deals with are also policemen from the police station. Where did he get the opportunity to deal with the criminal police brigade!

With his rich experience, he immediately knew that he was in trouble!

"Everyone...Brother...Ah, no, Uncle Policeman...What did I do?"

Uncle police?

Lu Sheng stared at the other party's unshaven appearance, and suddenly became speechless.

"You don't want to say it, do you? Come back to the police station with us first!"

......

trial room.

Lao Zhang was interrogating Xie Qin, while Jian Zhenguo and Lu Sheng were sitting outside, observing each other's every word and deed.

"Jane team, I think it is necessary to compare Xie Qin's body fluids with the DNA sequence of the blood moon murder case..."

Hearing this, Jian Zhenguo also nodded: "You also have doubts?"

"Well... I have read the file and know that every year the database is updated to compare the murderer's DNA. Xie Qin is a recidivist and a frequent visitor to the police station. If the murderer is him, it is impossible that there has been no movement in the past five years."

The interrogation of Lao Zhang in the room has already started, but Xie Qin has been complaining again and again.

"Uncle policeman, I really didn't go anywhere last night!"

"Yesterday happened to be the day of salary payment. The factory specially gave a one-night vacation. I must have gone to drink alone without working overtime!"

Of course, he had heard of a murder case near the industrial park. She was a young girl, and he was still feeling emotional at the time.
