When investigating a case, sometimes, many of the things the police do seem to be in vain. They conduct a large number of investigations and visits, constantly compile and summarize information, and constantly collect all information related to the victim. These things are often used in court in the end.
Very little is received. When a case is solved, the large amount of information collected in the early stage will be packaged and shelved, allowing it to gather dust all year round. However, in the end, why not do it if it is not needed?
The diary that had just been discovered was stolen. Although Fang Deren and others conducted a detailed inspection of the community, they still could not find the diary. Xu Lang and Ding Haoqiong stayed in Room 604 for a long time and found no new clues.
.
It was getting dark, and people who had been busy all day were going home one after another. Xu Lang and the others also left Lushui Community and returned to CSY.
After returning to CSY, Xu Lang entered the office and began to organize his thoughts.
Xu Lang was actually very confused. When he went to Room 604, no one told him that he went alone. The discovery of the diary in Qin Fen's bedroom was completely accidental. If it wasn't for Ma Chunmei from Room 504 downstairs who came to knock
It is impossible for Xu Lang to leave the door. Is this a coincidence?
coincide?
Xu Lang never believed that there were 100% coincidences in this world.
Qin Fen's death originally seemed to be just an accident. It was only because of the signs of Sun Wenyao's crime that the originally simple case became complicated. However, as the investigation of the case deepened, everything changed.
It becomes more and more complicated.
The death of Qin Fen, the disappearance of little Qin Fen, the flight of Qin Youqi and Qiao Lina, the possibility that Qin Fen was not Qin Youqi's biological son, and why Sun Wenyao killed Qin Fen, all these questions need to be answered one by one.
Xu Lang leaned on his seat and pondered for a long time. He felt that there might be something wrong with the previous direction of the investigation. Now, through his conversation with Ma Chunmei during the day and the diary that was stolen just after being found, it was proved
Got this point.
Since Qin Fen is now dead, and little Qin Fen is missing and his whereabouts are still unknown, then we should start from the source and investigate Qin Youqi and Qiao Lina. Perhaps, we can find a breakthrough from them.
Thinking of this, Xu Lang called Ding Haoqiong and others to express this idea.
Ding Haoqiong and the others were not surprised by Xu Lang's sudden change in the direction of the investigation. They just nodded and started working.
Soon, relevant information about Qin Youqi and Qiao Lina was compiled.
Qin Youqi, male, 55 years old, native of S city, has only been married once, and has two children, 33-year-old Qin Fen and 16-year-old little Qin Fen. Qin Youqi is a processing company in Chengxi District
The director of the factory, and there are hundreds of employees in the factory. Xu Lang already knew this information during the initial investigation. Now, what Xu Lang wants to know is Qin Youqi's family background.
Household registration management is a very good measure, which allows people to investigate a lot of things through a small household registration book.
Qin Youqi's father is not a native of S City, but a native of Yunnan City. Many years ago, due to various historical reasons, he came to S City alone to work hard. Then, he got married and had children here, lived and worked in peace and contentment, and finally moved his registered residence to S City.
Became an original resident of S City.
According to the report, Qin Youqi's father not only had Qin Youqi's one child, he had five children in total, three daughters and two sons. The three daughters were the top three children in the family. Perhaps it was because of the deep-rooted tradition of favoring sons over daughters.
In terms of ideology, after giving birth to three daughters, he still wanted two sons.
What surprised Xu Lang was that the two sons of Qin Youqi's father were twins. The eldest was named Qin Youliang, and the second was named Qin Youqi. However, the household registration showed that Qin Youliang died unexpectedly many years ago.
Qin Youqi's three sisters have been living in Yunnan City. The reason for this is that after their father could no longer live in S City, he sent the three sisters back to their hometown in Yunnan City. They had already married and established a household registration.
He was also transferred from the Qin family. As for Qin Youliang, he had been living with his younger brother and his father. When they had just grown up, their father passed away, and a few years later, Qin Youliang also went to Ningshi, Yunnan because of his
A relative died in an accident on the way back.
Seeing the name Qin Youliang, Xu Lang suddenly felt his eyes light up.
The time of Qin Youliang's death happened to be the year that Qin Fen was born, and Qin Youliang and Qin Youqi were twin brothers, so Xu Lang made a very bold guess.
If Qin Fen is not the child of Qin Youqi and Qiao Lina, then could he be the child of Qin Youliang and Qiao Lina?
When Xu Lang proposed this guess, Ding Haoqiong and others were shocked and found it very incredible.
"Brother Lang, is your guess too bold?" Luo Jiayan couldn't help but say.
Hearing what Luo Jiayan said, Lu Xing and Fan Yang couldn't help but nod. They felt that Xu Lang's guess was too unbelievable. After all, Qin Fen's body was still in CSY's morgue. Before, Qin Fen's body was still in CSY's morgue.
Mingyue conducted a DNA test on Qin Fen and Qin Youqi, confirming that they were related by blood and that they were father and son. Xu Lang's guess completely overturned the previous test. Compared with what people say, machines cannot lie.
Qin Mingyue shook her head and said, "This possibility is not impossible."
As soon as these words came out, everyone's eyes turned to Qin Mingyue, as if they wanted him to give a reasonable explanation.
"Qin Youqi and Qin Youliang are twin brothers. As you know, twins are divided into identical and fraternal twins. If they are fraternal twins, their DNA may be different, but for identical twins, their DNA will definitely be exactly the same.
, maybe, after they are born, due to family environment and personal experience, they will have differences in personality and appearance, but their DNA will not change unless there is a mutation, but this
The possibility is very small. If Qin Fen is really not the child of Qin Youqi and Qiao Lina, then he is probably the child of Qin Youliang and Qiao Lina. If Brother Lang's guess is true, then many problems can be explained clearly.
After listening to Qin Mingyue's professional explanation, everyone nodded and remained silent.
This kind of situation is not without precedent. A few years ago, in a city in the northwest, a robbery occurred that resulted in death. The thing robbed was not gold and silver, but a box of very valuable medicines. The crime was committed by a man.
For twin brothers, their purpose of robbery was to save their mother with the box of valuable medicines. However, due to the fierce resistance of the shop owner, during the struggle, the younger brother stabbed the shop owner in the neck with a fruit knife he carried.
The carotid artery was directly cut, causing the shop owner to die on the spot from excessive blood loss.
Not long after the incident, the police arrived at the scene and launched an investigation. At that time, although there were not many people around during the robbery, there were still witnesses, and the twin brothers were locals, and soon they were
Targeted by the police and arrested.
The case was solved quickly, but it was not possible to determine whether it was the elder brother who killed the shopkeeper or the younger brother who killed the shopkeeper, because the fingerprints of two people were found on the murder weapon found at the scene, and the two people often
Wearing the same clothes and looking almost exactly the same, it was impossible to tell who killed the shop owner at the time of the crime.
Before the shop owner was killed, he had a fight with the two brothers. During the fight, both brothers were injured and left blood stains on the scene. If it was a normal case, as long as the murder weapon was found, there would be blood stains of the perpetrator on the scene.
, and the testimony of eyewitnesses, the case can basically be closed. However, when the police extracted the blood stains at the scene and compared them with the DNA of the two brothers, a very embarrassing situation occurred, that is, the two brothers
The DNA is exactly the same.
After the two brothers were arrested, the elder brother admitted that he had killed the person, but the younger brother did not. The case could have been closed. However, during the trial, the younger brother reversed his confession in court and said that he was the one who killed the shop owner, not his elder brother, because
It was impossible to identify the two brothers who killed the store owner, and the suspect could not be identified, so the case was sent back for retrial.
Of course, this case was finally solved, not relying on DNA comparison technology, but through a surveillance video. After the police carefully watched the video frame by frame, they discovered a detail. Before the two brothers committed the robbery,
, and had a fight with the shopkeeper, and after accidentally killing the shopkeeper, they chose to escape in a panic. While escaping, the murderer's brother hit the door frame with his left ankle when he was passing by the door, and was scratched, leaving
There were bloodstains and bruises.
Based on this unexpected discovery, it was finally determined that it was the younger brother, not the older brother, who killed the shop owner. Faced with the new evidence given by the police, the two brothers finally admitted their crimes. In the end, they were severely punished by the law. This case
After months of investigation, the case of the twin brothers' robbery accidental death was finally settled.
Although the case is very simple, because the perpetrators are two people, and they are twin brothers, because the DNA is the same, it is impossible to determine who the perpetrator is.
This case had been reported on the official website within the public security system. Xu Lang and the others had seen it but did not pay attention to it at the time. Now that they think about it, the cases of Qin Youqi and Qin Youliang are very similar to this incident.
If Qin Fen is really Qin Youqi's child, then Qin Youqi will deliberately conceal Qin Fen's existence. During the early police investigation, when the people around Qin Youqi heard the name Qin Fen, they thought of their little one.
The son is the younger Qin Fen, not the eldest son Qin Fen. As parents, no matter how disappointing and unpromising their sons are, they will give their children a certain amount of care, but this is not the case for Qin Fen.
Qin Fen has no friends, as if he is living in a vacuum and a false world, with no one paying attention or even knowing his existence.
Everyone who has been to Room 604 feels that Qin Fen does not seem like a human being, he is like a pet kept in captivity. His name and the care he should have enjoyed have been replaced by his younger brother. Speaking of Qin Fen,
What people think of is the talented boy who was recommended all the way from elementary school to high school, not the slovenly man in his thirties who stays at home all day and lives in Room 604, which is like a garbage dump.
Qin Fen died. Qin Youqi and Qiao Lina didn't show excessive sadness when they saw his body. However, their son, little Qin Fen, was just missing, but they were in a hurry, like headless flies.
Generally, bumping around, is this normal?
Obviously, this is extremely abnormal.
Thinking of this, Xu Lang decided that if he wanted to find out the truth behind the whole case, he would first investigate the relationship between Qin Youqi, Qin Youliang and Qiaolina. Only by clarifying this can Xu Lang's theory be proved.
It seems to be wild and unimaginable, and whether the incredible speculation is tenable.
In addition, there is one more thing that needs to be done, and that is to investigate the truth behind Qin Youliang's accidental death thirty-three years ago. Was Qin Youliang's death an accident or a deliberate murder? As long as these two things are understood, perhaps,
All mysteries can be solved.
After some analysis and discussion, everyone came to this conclusion, so Xu Lang decided to ask Lai Pi and Luo Jiayan to rush from S City to Yunnan City tomorrow, and let the local police assist and cooperate. Firstly, they would find Qin Youqi and
Qiao Lina, secondly, found Qin Youqi's three sisters to see if she could find a breakthrough from them and find some clues.
As for Xu Lang and the others, on the one hand, they continued to search for Xiao Qin Fen, and on the other hand, they re-investigated Qin Fen's past.
The tasks were all clear and it was getting late, so Xu Lang asked everyone to simply clean up and get off work.
————
After walking out of the CSY office building, Xu Lang still didn't feel the slightest bit relaxed.
The new investigation direction is all based on the diary left by Qin Fen. Qin Fen is not Qin Youqi's biological son. If the diary is a forgery, then Xu Lang and the others are taking a detour in their current investigation direction.
It is a terrible thing. However, now that the investigation of the case has reached a deadlock, Xu Lang and the others must find a way to find a new breakthrough, and investigating the relationship between Qin Youqi, Qin Youliang and Qiao Lina is the best choice.
It was useless to think too much. When Xu Lang returned home, he found that Xiao Yueyue was already sleeping. Xu Lang did not disturb Xiao Yueyue, but simply washed up and returned to his bedroom to rest.
There was nothing to say or anything to do all night.
The next day.
When Xu Lang sent Xiao Yueyue to school and went to work at CSY, Lai Pi and Luo Jiayan had already taken the earliest flight from S City to Yunnan City. At this time, they were on the plane.
After Xu Lang learned about this situation, he immediately contacted the Yunnan City Police and briefly explained the situation to them. The world's criminal investigation is a game of chess. After receiving Xu Lang's call, the Yunnan City Police said without saying a word, he said for sure.
They will fully cooperate with this matter.
After contacting the police in Yunnan City, Xu Lang looked through the previous investigation materials on Qin Fen's past. He found that the previous investigation of Qin Fen was still too general and vague. The people the police interviewed, except for Lu
There are only some residents of Shui Community who are known to Qin Youqi and others. There is still too little investigation on Qin Fen's school days. After all, Qin Fen is already thirty-three years old and has graduated many years ago. Many of his old classmates have already
They have gone their separate ways, and it is not easy to find them. As for Qin Fen's former teachers, some have retired and some have passed away. Those teachers who are still teaching do not have a deep impression of Qin Fen as a student.
Xu Lang felt that it was necessary to visit and investigate again.
In addition to re-visiting and investigating Qin Fen's past, Xu Lang and the others also need to find a way to find Xiao Qin Fen and see where he is.
Why did this boy who was only sixteen years old choose to run away from home without saying a word after his brother was killed, and also cut off all contact with the outside world? What kind of connection did Qin Fen's death have with him?
Only after finding Xiao Qin Fen can we know the truth.
After Xiao Qin Fen disappeared, the police investigated many places based on his identity information, but so far found nothing. Xu Lang felt that since Xiao Qin Fen did not leave S City, then he must still be in S City, and now that the police
If Xiao Qin Fen was not found in the hotel, then the most likely possibility is that he lives in a rental house. Only in this way, he does not need to use any identity information.
Thinking of this, Xu Lang contacted various public security bureaus and police stations and asked them to conduct research on the rental house.
This kind of investigation and sorting work requires a lot of manpower and material resources, and it also takes time. It is the most inefficient and slowest method. However, this is also the impossible method. Only in this way can we determine whether Xiao Qinfen is still in S city.
After doing all this, Xu Lang looked through the investigation information about Xiao Qin Fen and Qin Fen. He found that the elementary school and junior high school that Xiao Qin Fen attended were the same school. In this case, Xu Lang decided to go to the school.
Take a look and look up Qin Fen's classmates and teachers. Perhaps, you can get some unexpected clues from this.
Lai Pi and Luo Jiayan went to Yunnan City to investigate Qin Youqi's affairs. Fan Yang returned to Room 604 again because of the problems Xu Lang discovered in Room 604 yesterday to conduct further investigation work to see if there were any problems at the scene.
The clues I missed during my first survey.
The search for Xiao Qin Fen cannot be left to people from various public security bureaus and police stations. CSY also needs help, so Ding Haoqiong and Lu Xing went there.
Now Xu Lang needs to go to school to understand the situation. Because of what happened yesterday, Xu Lang decided not to act alone, so he took Qin Mingyue with him. Anyway, Qin Fen's autopsy report has come out, and Qin Mingyue has no work to do for the time being.
, along with Xu Lang and Qin Mingyue was his assistant Ren Xue.
