Stay away from Conan.

Chapter 10 Night Baron
Hattori Heiji looked around at everyone's expressions, and then explained proudly.

"After a person dies, the heart stops beating, and even if the artery is cut, the amount of bleeding is limited. Therefore, such a large amount of bleeding at the scene was caused by the deceased before his death. Now, judging from the coagulation of the deceased's blood at the scene, the death time of the deceased is less than now. Not far. When I entered the door, I found that the entrance of this store was under surveillance, and it would be too conspicuous for the murderer to leave the scene in such a short time, so in order not to be suspected, the murderer must still be hidden among you people at the scene!"

"But the murderer doesn't have to go through the main door when he comes in or leaves."

Gao Yuan was speechless.

"But it's wise, you have to know that in addition to the main entrance, the back door of our store is always locked from the inside. If the murderer doesn't go through the main entrance, there is no other way out."

The store manager Kinoshita Kawashi explained.

"That's right. When I first came here, I looked at the back of the store and found that the door was indeed locked from the inside. If the murderer really left there, it could only be that the murderer had an accomplice and was still in the store. However, no matter what, all of you at the scene are suspects, either the real culprit or the accomplice!"

Hattori Heiji said excitedly, especially after hearing Takato's narration just now.

Gao Yuan sighed, "There is actually something strange about the scene. There are so many bloodstains, but the murderer did not step on them and left footprints. As you said, such a large amount of blood was left by the deceased before his death. Considering the cause of death of the deceased, the murderer must have remained at the scene before the death of the deceased, so it seems very strange that the murderer left the bloody scene without stepping on it."

"What's the matter, the murderer just needs to be more careful. You see, Officer Otaki didn't step on it when he entered."

Hattori Heiji said nonchalantly, "And when the murderer left, the blood may not have spread as it is now."

Gao Yuan knew that he didn't make a point, so he continued to explain.

"Don't you think the murderer will look suspicious if he leaves the box carefully through the door? What would you do if you were the murderer and wanted to leave the scene without being discovered?"

"That's okay, of course I'm sure there's no one in the corridor..."

As Hattori Heiji was speaking, he suddenly realized what Takato wanted to say.

If the murderer leaves the box through the door, in order to ensure that he will not be discovered, it is best to confirm that there is no one in the corridor, but once he wants to do this, he must approach the door to listen to the movement outside the door, or it is best to see it with his own eyes. Check the situation outside the door, but there is only such a small space in the whole box, to do this kind of action, you must be close to the door, and the blood in the box should have spread to the door, so the murderer must confirm that there is no one outside the door It was too difficult.Unless the murderer didn't confirm at all, he just opened the door and left.But the murderer is really so bold, isn't he afraid of being seen?

Looking at Gao Yuan, Hattori Heiji understood that Gao Yuan had thought of this a long time ago before he said what he said, but if this is the case, how did the murderer leave.

Looking at the situation in the box again, Hattori Heiji noticed the vent on the roof.

"You mean, the murderer entered the scene through the ventilation duct? Impossible, this vent is fixed and sealed with screws. Even if the murderer enters the scene through it, the screw must be removed. It is impossible for the deceased not to notice the movement of doing this! Unless the murderer knew the deceased and was not surprised by the murderer's appearance... But this is not right, the murderer should have a great hatred against the deceased!"

After thinking for a long time, Hattori Heiji felt that his head was a little big, and he felt that he was being entangled in it.

"It may not be as complicated as you think, but the truth depends on the situation of the vent. Officer Otaki, please go up and see if there is any glue or other things left on the edge of the vent."

Gao Yuan said.

"Do you suspect that the vent was removed at the beginning, and then fixed with glue or something, and the murderer just needs to push hard when he comes in? Then when he leaves, he fixes it with screws so he won't be discovered?"

Heiji Hattori understood the word "glue" in Takato's words.

Takato responded with an "um", which made Hattori Heiji feel that he underestimated this young brother who claimed to be a detective.

Of course, it's not such a great thing to think of this, it's just because similar tactics have appeared in the Lavender Villa incident before, so when Gao Yuan thought that the murderer might come and go through the vent, he naturally had this kind of suspicion.

Officer Otaki immediately took action, stepped on the table, reached out and touched the edge of the vent carefully, and sure enough, he felt some sticky touch, and gave an affirmative answer.

"If this is the case, the murderer obviously came to this box to tamper with in advance, but how can the murderer be sure that the deceased will come to this box?"

Hattori Heiji was puzzled.

"Before that, I have a question to ask."

Gao Yuan looked at the employee who brought the registration materials from the front desk just now.

"Did the network problem in our store happen after the deceased came to the store?"

When asked, the employee suddenly seemed to remember something, "It seems like this, I remember that day the deceased came to our store to surf the Internet for the first time, and soon we received complaints from customers that the Internet in the store was poor, and the deceased It was a rare customer who did not come to complain that day, so I have some impressions."

And hearing this, the store manager Kinoshitagawa Shi looked at Gao Yuan, as if he understood something.

"Sensible, what do you mean by that?"

"Well, I have been managing the store's network for the past few days, and found that the culprit of the network fluctuations comes from the store. Presumably, someone came to the store to surf the Internet and installed malware on the store's computers, which affected the entire store's network. Come here, you can't help but feel a little suspicious."

The store manager asked Gao Yuan for affirmative answers as if to ask questions.

"But why would he do it?"

Kinoshita Chuanshi was puzzled, and Hattori Heiji on the side also pricked up his ears when he heard the unexpected clue.

Gao Yuan really didn't think about this question carefully. After thinking about it for a while, Gao Yuan suddenly asked, "Did the network problem happen after that employee asked for leave?"

After Gao Yuan asked such a question, the employees in the store suddenly realized that it was true.

Hattori Heiji, who had listened to their remarks, also said: "Speaking of which, the murderer had to do something in the store in advance, which shows that he knows the structure of this Internet cafe very well. In this way, the employee who asked for leave you mentioned is very Suspicious!"

At this time, the siren sounded outside the door, and the police who had just received the alarm came to the scene, but it seemed that all of them were officers of Police Officer Otaki. In addition, the police were specially sent to investigate the ventilation ducts, and considering what Hattori Heiji said just now, they planned to go to the home of the employee who asked for leave to investigate.

"How is it? Do you want to go to the home of the employee who asked for leave?"

Hattori Heiji invited Gao Yuan.

Gao Yuan was about to readily agree, when an employee ran over in a panic and said to Kinoshitagawa: "The store manager! It's not good! The server in the store..."

Hearing this, Takato's expression changed slightly, and he ran towards the main computer that manages the server in the store. The store manager and Hattori Heiji also followed closely. Seeing Hattori's hurry, Kazuha and police officer Otaki also hurriedly followed. .

When I came to the main computer, I saw that the data in the server was being deleted by an unknown program!

There is a virus program that bypasses the firewall written by myself!And the emergency procedures were not triggered!

Gao Yuan did a few urgent operations but was unable to recover!
Night Baron!

Gao Yuan subconsciously thought of the name!
