Detective Conan: The Ultimate Growth Space

Mori said, "This is troublesome. Although we have a certain scope now, it's too big. We have no way to investigate."

Officer Shiratori added, "Yes, even if we knew, it wouldn't make a difference. The scope is too broad; we can't possibly prevent it all."

Miwako then said, "Inspector Megure, why don't we apply to the higher-ups to release some details of the case so that the public will be alerted and the culprit will find it difficult to commit the crime?"

Inspector Megure nodded and said, "After we finish discussing this, I'll apply to my superiors. We can't give the murderer another chance to commit the crime."

Regarding what the two said.

Everyone agrees with this.

This may put more pressure on the police, but it can also serve as a reminder to the public, making them more vigilant.

At least unlike the previous four cases, the victims were not caught off guard when attacked by the perpetrator, which made it so easy for the killer to succeed.

Zhi Yong said, "Based on the clues in the data, I narrowed down the suspect to a certain range before. The fourth case just happened recently. When you go to the area where the crime occurred, someone should remember what the suspect looks like."

Chapter 569 The So-Called Vampire

Regarding what Zhiyong said.

This is also a necessary step for the police.

Inspector Megure nodded and said, "Good, Miwako. In a bit, take your men and investigate the area around there."

Miwako replied, "Yes."

Zhiyong added, "I have further reasoning about the murderer."

Inspector Megure hurriedly asked, "Tell me!"

Everyone looked at Zhiyong.

He replied, "The murderer is probably between twenty and thirty years old. He is thin and about 1.7 meters tall. He looks like a drug addict with messy hair. His appearance is very distinctive, so someone will definitely notice him. Also, based on the murderer's description, I have drawn a rough sketch."

As he was saying this, it was just before.

According to Mariko Toma's description, the portrait of the murderer that he had drawn was brought out.

Upon seeing the portrait.

Some people still had doubts.

Miwako asked in confusion, "Is this criminal profiling technology?"

Zhiyong nodded and said, "That's right."

Inspector Megure asked, "What is criminal profiling technology?"

Miwako replied, "This is a method that I heard my teacher introduce during my training in the United States. It is based on the understanding of crime phenomena formed by multiple disciplines such as psychology, sociology and criminology. It analyzes the physical traces and psychological traces at the crime scene and the victim's life trajectory to portray the most likely characteristics of the perpetrator in the investigation."

Officer Shiratori also said, "I've only heard of this method before, but I've never actually seen it. I never expected to see it here."

Mori exclaimed in surprise, "Isn't that incredibly powerful?"

Zhi Yong shook his head and said, "This requires clarifying all the clues in the case in order to get a relatively accurate result. If the clues you know are wrong, then the murderer described based on the clues will be very different from the real murderer."

Inspector Megure nodded and said, "I see."

Mori asked, "This time, how accurate is your description of the murderer?"

Zhi Yong replied, "It's impossible to say 100%, but it's still 70% or 80%. Actually, I said before that the murderer should have some kind of blood disease."

Inspector Megure nodded and said, "I'm also investigating this matter. Do you have any other opinions?"

Zhiyong added, "I actually have some thoughts on the blood disease the murderer had."

Inspector Megure asked, "What do you want to say?"

Zhi Yong asked, "I'm sure everyone has heard of vampires. The reason this case is being kept secret for now is because we're afraid that the legend of vampires might cause social unrest."

Inspector Megure nodded and said, "That's right, that's why the news was suppressed."

Zhi Yong replied, "Actually, I have read some books and I have some scientific views on so-called vampires."

Mori asked, "Do you believe that vampires exist in the world?"

Zhiyong nodded and said, "It's just that it's a little different from what we read in novels. From what we know, vampires have two characteristics: first, they feed on blood, and second, they are afraid of sunlight."

Miwako replied, "That's right."

Zhiyong added, "Actually, I think there are vampires, but these people probably have a blood disease."

Officer Shiratori asked, "Oh, what's wrong?"

Zhiyong replied, "Porphyria."

Inspector Megure asked, "What is porphyria?"

Zhi Yong explained, "This is a blood disease, a very rare condition. There are very few such cases in the world. Porphyria is a group of porphyrin metabolic disorders caused by a deficiency of a certain enzyme or a decrease in enzyme activity in the human body. The main clinical symptoms include photosensitivity, digestive system symptoms, and neuropsychiatric symptoms."

Officer Shiratori asked, "The photosensitivity you mentioned, is it the same as being afraid of sunlight?"

Zhi Yong nodded and said, "That's right. The amount of porphyrin, a photosensitive pigment in the body of porphyria patients, is a hundred times that of normal people. Therefore, once exposed to sunlight, porphyrin will be converted into corrosive botulinum toxin, causing severe deformities of the body and face, complete corrosion of the ears and nose, and after the teeth are corroded, all the teeth will turn into red wolf teeth, and the skin of the whole body will be severely whitened."

Miwako asked, "Is this why he craves blood? Is he trying to use blood to give himself psychological comfort?"

Zhi Yong replied, "Yes, this disease can also induce bipolar disorder, paranoia, and schizophrenia. The obsessive-compulsive delusions about the craving for fresh blood are extremely severe."

Mori also said, "If that's the explanation, then in ancient times, because medicine was underdeveloped, people would think that patients with this disease were vampires."

Everyone nodded.

After all, many legends from ancient times have reasonable scientific explanations today.

There are still many questions that cannot be explained scientifically.

This is simply because we still know too little about the world today. Just like some modern science, if placed in ancient times, it would be seen as a miracle.

Inspector Megure nodded and said, "So the legendary vampires are infected with this disease."

Miwako also said, "If that's the case, even if we release part of the case information, it won't be a big problem. However, before releasing the information, we need to disclose the details of the illness to the public so that people understand that the so-called vampire is just a disease. In that case, when we release the case information to remind the public to be vigilant, it shouldn't cause too much of a problem."

Zhiyong replied, "We still have time. Let's report to our superiors first. We can hold off on an announcement for now, but let them prepare. We should quickly investigate patients with this disease in Tokyo and send people to the vicinity of the fourth case to have them identify the portrait I drew and see if it has appeared there. Once we confirm, we can proceed with our next steps."

Inspector Megure nodded and said, "That's right."

Regarding this matter...

The police leadership will definitely need to hold a meeting to discuss this, and they will also need to report to the government.

The entire process is now complete.

Finally, the government agreed to the plan.

Zhiyong suspected that with so many clues, the murderer should have already been caught.

After all, this is not something that one person can decide.

……

Chapter 570 confirms the killer's appearance.

The meeting is now almost over.

at this time.

Inspector Megure said, "Brother Sato, you know a lot about this disease. Please help us gather information about it. Inspector Shiratori, you'll be in charge of this matter."

Officer Shiratori immediately replied, "Yes, sir."

Zhiyong also said, "No problem."

"Miwako, take your men to the vicinity of the fourth case and look for anyone who has seen the murderer. Then have them confirm the portrait drawn by Sato-kun."

"Yes."

Inspector Megure continued, "Takagi, take your men to major hospitals and investigate detailed information on porphyria patients. Also, compare this portrait with the patient's appearance to see if there are any other patients who look the same."

"Yes."

Miwako and Takagi leave.

At this moment, Maoli asked, "Zhiyong, your analysis is correct, but according to you, the murderer has porphyria, so he should be afraid of sunlight. The first three cases all happened at night, but today the murderer committed the crime during the day. Before the rain, the sun was shining in the sky. Isn't that different from your analysis?"

Inspector Megure, upon hearing this, also said, "Yes, that's certainly true, Sato-kun. There's definitely something wrong with that."

Zhiyong nodded and said, "I'm also thinking about this. It's quite strange to me, but we don't have enough clues right now, so I can't make a judgment. However, I think investigating the people in the portrait and investigating porphyria patients are both correct."

Inspector Megure asked, "Oh, why do you think that?"

Zhi Yong replied, "The portrait of the murderer was drawn based on the clues I obtained. Even if it's not 100% accurate, I'm fairly confident. Moreover, as long as we investigate the area surrounding the fourth case, we should have results soon."

Mori asked, "What about porphyria?"

Zhiyong added, "I also think there's nothing wrong with investigating porphyria. Even if the murderer didn't have porphyria, it's possible that his relatives did."

Inspector Megure asked, "Do you believe it's possible the killer killed someone for their family's blood?"

Zhi Yong shook his head and said, "While that possibility exists, I still believe that the murderer took the blood for himself. If the murderer was after his family, then the escalation of this blood-taking would be a bit strange."

Inspector Megure also said, "Yes, if the murderer was after a family member, he would only have killed to obtain more blood, rather than demanding higher quality blood so quickly."

Mori then asked, "But if the murderer was doing it for himself, how could he do it during the day? People with porphyria can't stand in the sun."

Inspector Megure replied, "Could it be that the culprit is only in the early stages of porphyria?"

Zhiyong replied, "Porphyria patients crave blood, but drinking blood doesn't cure or suppress the symptoms. Rather, it can trigger bipolar disorder, paranoia, and schizophrenia."

Mori also said, "That means the murderer suffered from porphyria, which affected his psychology. He had mental problems and, in order to avoid death, he craved blood."

Zhiyong nodded and said, "That should be the case. If porphyria has progressed to this stage, it can't possibly be in the early stages."

Inspector Megure said, "If that's the case, then it's very strange."

Zhi Yong said, "We still have too few clues. Let's wait for the investigation results before we analyze them. At least I think we're on the right track right now."

Inspector Megure nodded and said, "That's all we can do for now."

The police currently have no direction for their investigation, so perhaps what Zhiyong said is problematic. However, they have no choice but to continue their investigation in this way, hoping to obtain more information from it.

Now all Zhiyong can do is wait.
