The next day, when the policemen from the criminal police detachment went to work, they saw Zhang Yu staring blankly at the whiteboard in the office with a pair of red eyes.
The whiteboard was now covered with photos of the case, and several keywords were written on it.
A colleague came over curiously, but frowned.
The above photo is too familiar. It was from a dismemberment case that happened last year, and the deceased has not yet been identified.
Because the deceased who was tied in a fishing net and tied with a foam board had completely turned into a skeleton. When he was discovered, there had just been a rare heavy rain. The deceased was swept along the street no matter how far he was. At the same time, he was also washed away.
All traces were washed away, and even the surveillance cameras along the way did not capture any suspicious figures.
The skeleton of the deceased had no trauma or disease. Judging from the degree of decay alone, he should have been dead for more than half a year. However, the soft tissue was intact, and judging from the degree of calcification, it seemed that he had been dead not long ago. The cross-section under ultraviolet fluorescence showed that it was still very fresh.
Since the head cannot be found, it can be determined that the deceased was a female. She was about 35 years old at the time of death, 1.65 meters tall, and had a history of childbirth. The dismemberment method was not professional. It should have been a saw and an axe, and the body was dismembered.
Freezing. But based on these alone, even the time of death, the manner of death, and the specific appearance of the deceased cannot be determined.
Because of this, after investigating all the recent missing persons reports, but none of them could match the skeleton, the investigation reached a deadlock.
Unexpectedly, today, Zhang Yu would put this case on the table again.
When everyone arrived, team leader Qin Sen also walked in holding a cup filled with strong tea and nodded to Zhang Yu.
The latter sent text screenshots of the first three chapters of "The Killer's Diary" to the Weiwei group.
There were a few thousand words in total, and it only took a few minutes to read it. After everyone had read it, Zhang Yu asked: "What do you think?"
In fact, while reading the novel, some people kept showing signs of surprise and kept looking at the whiteboard in front of them.
"I just checked on the Internet. The author of this novel is Mei Qian. Is he also related to the corpse dumping case? That's not right. He was still in the detention center when the crime occurred and had no time to commit the crime." Li Chen raised his hand actively.
.
"Isn't he seriously injured? He can still write a book in this situation, which is very dedicated." Someone whispered in a low voice.
"Since he didn't have time to commit the crime, where did he get the details? You must know that the news about this case has not been exposed at all."
Zhang Yu and Qin Sen looked at each other before nodding and said: "Yes, if it can be confirmed that Mei Qian is the murderer, the first thing we do at work will not be a meeting, but go to the Four Seasons Garden with a search warrant." As he spoke, he
I picked up the charcoal pen and now drew a circle on the whiteboard with the word "time".
"The time in the novel is August 14th, which is actually six days different from the incident. The real time of dumping the body was August 20th, but one thing is very accurate, it was a heavy rain." As he said, he wrote under the time.
At 8.20, I wrote the word "heavy rain" again. Then I circled the word "location".
"The Xiaguan District in Mei Qian's novel is obviously fictitious, but there are only a few low-lying places in our jurisdiction, which narrows the scope of the investigation."
"Wait!" Someone raised an objection: "We are looking for the murderer based on a novel. Isn't it a bit too childish?"
Zhang Yu smiled and explained: "Although I think it's ridiculous, many details in the book are consistent with the case. I don't know where he got the news from, whether he found clues or made it up.
It provides us with new ideas for solving the case.”
Then, he circled "Dispose of the Body", pulled out an arrow, and wrote the word "maggot".
Then he said slowly: "The method of disposal of the body is basically consistent with the forensic speculation. The murderer froze the body after dismembering it, and used a knife to remove the flesh from the bones. The remaining parts were left to be corroded by fly maggots. This is also the body of the deceased.
The reason why the degree of corruption does not match the time estimated by forensic medicine.”
"My so-called idea for solving the case lies in a description in the book. First of all, the murderer must be an old resident, which also explains why the surveillance camera did not capture him. He is familiar with all the nearby terrain and surveillance facilities, plus the heavy rain
, it is easy to escape surveillance. Moreover, the novel also focuses on the fishing nets binding the corpses, which cannot be described as a simple coincidence."
"However, we have also investigated families with no children in recent years, and women have gone out, and there is no news about them. We have gained nothing."
"What if the couple all disappeared and no one reported the case?" Zhang Yu asked, adding: "There is a description in the book, 'I arrived at their new home and spent a wonderful night...' They are used here, I
Personally, I speculate that there may be another deceased person. At first, we initially suspected that it was the murder of my wife, and we checked the identity of the deceased from the missing person report, but naturally there was no result."
Then he wrote the word "Jiahui" under the photo of the deceased's body, and after thinking about it, he drew a question mark. Under the heavy rain, he wrote "more than a dozen photos", and pulled an arrow to connect it directly with "Jiahui"
.
"Mei Qian's novel gives a key description of the time, place, method of dumping the body, and even the murderer's motive and psychology. I combined existing clues and the content of the novel to create a profile."
After a pause, he took a sip of water, and then continued loudly: "I think the murderer has the following characteristics -
Psychologically, the murderer may have a fetish for SHI and have a possessiveness beyond ordinary people towards the things he likes.
He should be an ordinary-looking person with a fat body and a withdrawn personality. He shows low self-esteem and introversion. He is about 40 years old. Even if he is walking on the street, he is easily ignored and even relatively greasy.
Your residence or work place should be in the old city of Xiadu, and you are from a local household. At least in the past few years, you have never left Xiadu. You are familiar with the nearby terrain and all surveillance, and you are good at hiding.
When I was a teenager, I had a childhood sweetheart with whom I have been secretly in love. Most likely I have no fixed partner and live alone.
His profession is definitely not a doctor, butcher or other related profession, because the method of dismembering a body is rough and has no medical knowledge. But he can know how to use maggots, so he should be a fan of criminal investigation novels or TV series.
If the family is unknown, there is a high probability that the person will not live a happy life, which will lead to low self-esteem and distorted character.
Having his own means of transportation would at least allow him to easily take the dismembered deceased home for disposal.
Judging from the behavior of taking more than a dozen photos and posting them online, it seems that he also likes to show off himself. Dumping the body in the heavy rain may also be to show off..."
After finishing this long speech, Zhang Yu took the water glass, found a stool and sat down, drank water slowly, and watched his colleagues commenting on his words.
It wasn't until the captain Qin Sen straightened up and clapped his hands that the office became quiet. He said in a deep voice: "Temporarily lock in all the new communities within the jurisdiction, and contact each property management or neighborhood committee to investigate the arrears of property fees or health management fees for more than two years.
Neither husband nor wife can find the family. In addition, we will find the local people who posted photos online during the heavy rain last year and investigate them one by one." At this point, he sighed: "Although I don't think Mei Qian's novel can solve the case.
The key, but this case has been delayed for a long enough time. This is at least a new entry point. Let's work hard and give the deceased an explanation."
After the meeting was over and everyone went to work, Zhang Yu followed Qin Sen into the captain's office.
"Captain, if this "Killer Diary" can be confirmed, does it mean that Mei Qian's tomb robbing novel is also a pure coincidence, and he is just an unlucky crow's mouth? After all, the subway line was rerouted twice and he didn't escape. It's hard to say that.
It’s really unreasonable.”
Qin Sen looked at him, pondered for a long time before sighing: "From my heart, I don't want Mei Qian to be a criminal, otherwise, this person will be too terrible, and he will make a fool of the police and everyone else. But do you want to
Have you ever, how do you explain that satellite photo?”
