When King Du Yan was weak, he had already made great achievements in military affairs. He held a high position and was in charge of a department. He was famous in the four or nine cities.
To be honest, a cadre at the level of director is really nothing in Sijiu City.
But Du Weiguo is the director of the Special Service Department. Once he is released, he will be promoted to at least one level. You know, he is only 23 years old.
Now he is definitely the idol of young colleagues, not even one of them.
Du Weiguo reached out his hand with a warm smile and said in a gentle tone:
"Hello, Comrade Zhou Nan, I am Du Weiguo."
This Zhou Nan looks very young, about 25 years old, and should be similar to Du Weiguo's age, or even slightly older.
He was a little panicked at this time, his face turned red. When he saw Du Weiguo's outstretched hand, he quickly wiped it on his clothes.
Then both hands stretched out together and held Du Weiguo's hand tightly, with an excited tone:
"Prince Du Yan, no no, Director Du, hello, I, I am Zhou Nan, you may admire me~~"
Zhou Nan was so excited that he even said the opposite of what he said, but Du Weiguo didn't mind this and said politely with a smile:
"Haha, Comrade Zhou Nan, you are too polite! I am just a reckless man who only knows how to fight and kill. That's why I got the nickname Du Yanwang.
You are the real experts in these intricate criminal investigation tasks, and I am here to learn from them today."
Du Weiguo's words were very modest and somewhat hypocritical.
But obviously Zhou Nan, like Hou Shengli, has a straightforward character, but he just likes this.
His face glowed with praise and he was speechless. He didn't know what to say. Although Hou Shengli felt very happy.
But he still had to be more serious after all. Looking at Zhou Nan's expression that looked like a lunatic, he felt a little embarrassed for no reason.
He reached out and punched the back of Zhou Nan's head, and scolded angrily:
"A guy with no 2-liter bones! Just a few words of praise, but I can't find Bei?"
He is really worthless. Director Du is so humble. It took a lot of effort to invite this true god here.
Why don’t you just stop being confused and introduce the details of this case to Director Du in detail!"
"Oh, oh, yes!"
After Zhou Nan took a few blows, it was like waking up from a dream.
He quickly let go of Du Weiguo's hand, looked solemn, and said in a deep voice:
"Du Chu, this case happened 10 days ago. The police station received a report from a neighbor about this family~~"
Zhou Nan is a comrade with very good logical thinking and is very solid in his work. He introduced the case very clearly and confirmed most of Du Weiguo's judgments.
The specific facts of the case are as follows:
The man in this family is named Jin Guihai. He is an ordinary clerk in the district government agency. He is 36 years old and is a third-level clerk.
In addition to him, there is a daughter-in-law, two children, and a mother-in-law in the family, a total of 5 people living together.
He is a live-in son-in-law who works for his father-in-law. His wife has no job and her mother-in-law is sick and has been bedridden for many years.
Ten days ago, the police station received a report from a neighbor in the apartment building, saying that there was an extremely strong putrid smell in Jin Guihai's home.
At that time, the door of Jin Guihai's house was locked with an open lock. It was said that the whole family had gone to send the mother-in-law back to their hometown to choose a cemetery, and there was no one at home.
The rancid smell was so strong that it could be clearly heard on the entire second floor when comrades from the police station broke in.
They found Jin Guihai lying on the ground. His body was highly decomposed and covered with white maggots.
This kind of murder is considered a major case and must be reported to the city bureau.
So the Criminal Investigation Section 2, which Hou Shengli was in charge of, took over this murder case. It took 10 days to handle it, but there was no clue. It turned out to be a mysterious secret room murder case.
According to Zhou Nan's introduction, Jin Guihai's daughter-in-law, mother-in-law, and two children locked the door and left Sijiu City at 1 p.m. on April 28.
His mother-in-law’s hometown is Zhaiwang Township, Yangxin County, Binzhou, Shandong Province.
Hou Shengli, Zhou Nan and others did their work very carefully. They had confirmed it via telegram and the local police station immediately.
His daughter-in-law Miao Cuilan and her mother-in-law indeed took the train and arrived in Yangxin County on time, and they did not leave their hometown during this period.
Through the autopsy, it can be initially determined that Jin Guihai's death time was between 2 a.m. and 5 a.m. on April 29.
Therefore, his wife Miao Cuilan and her mother-in-law have alibi, and their suspicions can be eliminated.
As for the two children, they are still young and do not have the ability to commit crimes.
The windows of his house are sealed tightly, the door is locked from the outside, and the lock belongs to his house, which the neighbors can be sure of.
Because there is an old lady in Jin Guihai's family who has been sick in bed for many years. This is a bottomless pit, so the conditions at home are very difficult.
In fact, no matter what era, as long as it is an ordinary family, there will always be a patient who has been bedridden and taking medicine for many years.
It must be beyond one's means.
Not to mention the little money I had accumulated in the past, almost all the valuable things in the house have been sold.
But this brand new door lock was a prize given to Jin Guihai by his employer on New Year's Day this year when he was recognized as an outstanding worker.
He was reluctant to sell it, and it was the only brand-new item in his home.
As for the cause of Jin Guihai's death, the liver and spleen were directly pierced by a sharp knife, from the front abdomen to the back, causing massive bleeding to death.
Judging from the wounds, the crime tool can be determined to be a Type 56 three-edged bayonet, killing him with one blow!
The reason why it was classified as murder rather than suicide was that the tool used to commit the crime, which was the three-edged bayonet, was not found.
Second, the piercing angle is still powerful, making it difficult to commit suicide.
Recently, Hou Shengli was responsible for 2 subjects.
Jin Guihai's social relationships and everyone who is linked to him have been thoroughly investigated.
He is an honest man like an old scalper.
I usually work diligently, work hard without complaining, be taciturn, and get along well with my colleagues.
Moreover, at home, Jin Guihai is the kind of son-in-law who comes to the house, and he is also the kind of person who cannot fight back or scold him.
His job is only in the logistics warehouse of the district committee's agencies. He is only responsible for some ordinary chores and does not involve any secrets or games between big shots.
All in all, Jin Guihai is as little a person as dust.
He has no enemies at all, and no one in his social circle has a motive for committing the crime!
After listening to the case introduced by Comrade Zhou Nan, Du Weiguo couldn't help but fell into deep thought.
Good guy, this is really a secret room crime!
The windows at home are closed, the door is locked, the family is thousands of miles away, and no one around has any motive for committing the crime. It is really interesting!
After pondering for a moment, Du Weiguo lit another cigarette, exhaled a long puff of smoke, and asked in a deep voice:
"Zhou Nan, are there any signs of prying on this door lock?"
"No, Du Chu, we have already authenticated it, and we can be sure that it has never been pried, not even scratched!"
Zhou Nan answered decisively, and Du Weiguo frowned slightly and continued to ask:
"So when did the wife of the deceased Jin Guihai come back? Where is she now? Can I see her?"
Zhou Nan still answered without thinking:
"Du Chu, his wife is still in her hometown in Binzhou. When she heard the news of Jin Guihai's murder, his mother-in-law was so sad that she died.
His daughter-in-law Miao Cuilan, after the funeral, was so violently stimulated that she fainted and passed out. She is still hospitalized to this day."
"Um, fetal air?"
Upon hearing this, Du Weiguo's eyes narrowed, his sword eyebrows were unsheathed, like a sword, he pointed diagonally at the sky, and the corners of his mouth unconsciously made a beautiful arc.
In the photo of the bedroom in the north room just now, the slightly pretty appearance of the woman came to mind.
Du Weiguo's expression became a little playful, and he asked with a smile:
"Zhou Nan, when you were doing the background check, how is Jin Guihai's relationship with his wife and mother-in-law?"
Upon hearing this question, Zhou Nan hesitated slightly:
"Well, according to neighbors, the couple had a good relationship when they first got married.
But when his wife was pregnant with her second child, her mother-in-law suddenly fell ill.
From then on, the family's financial situation plummeted, and there were frequent quarrels at home. Usually the wife and mother-in-law would call him a coward, but he would remain silent."
Du Weiguo laughed silently, a look of understanding appeared on his face, took a puff of cigarette, lightly dusted the cigarette ashes, and asked softly:
"Zhou Nan, there are blood stains in the living room and on the bed. Judging from the blood stains, we can conclude that it came from Jin Guihai, right?"
"Uh, that's right! It must be Jin Guihai's! The traces of the scene at that time are very clear~~"
Du Weiguo suddenly asked such an irrelevant question, but Zhou Nan did not react immediately.
However, he did a very solid job in basic work. After being stunned for a moment, he answered fluently and full of details.
Du Weiguo nodded, then sneered, changed the topic, and his tone became a bit sad and sighing:
"Oh, it seems that Jin Guihai usually lives in the living room, while his wife sleeps in the north bedroom with her two children.
Even if his wife is not at home, he sleeps outside alone."
When Du Weiguo said this, he put out the cigarette butt and asked in a slightly teasing tone:
"It is especially obvious that the two of them are in a very obvious state of separation. According to what you said, Jin Guihai's family is living in isolation, and they quarrel and get scolded every day.
We also have an old mother-in-law who is bedridden for a long time and two and a half-year-old children at home. Do you think they will still share the same room?"
After Du Weiguo finished speaking, he looked at Zhou Nan with playful eyes.
"Du Chu, are you saying that this Miao Cuilan is not pregnant with his child, but that she colluded with an adulterer to murder her husband?"
After all, Zhou Nan is an elite old criminal detective, and he can tell the truth at once. He slapped his forehead suddenly, his eyes were shining, and his tone was filled with indescribable excitement.
"Contemporary Pan Jinlian?"
Hou Shengli also looked solemn and said in a deep voice.
