A mysterious invitation from a self-proclaimed "fallen god believer" embarks on a thrilling journey through the castle. The "butterfly" with a strong smell of blood www.biquge.info the pen and the fun pavilion flickered like a ghost.

………………………………………………………………………………………………………

It has been two days since Zhang Dagui's case, and in the past two days, there has been nothing to do in the detective agency as always, except that the atmosphere is a little duller than before, nothing else has changed.

Today, seeing that Mu Zihan, who had been hiding in the room for two days and hadn't gone out, came to the office, it seemed that after two days of rest and adjustment, he finally recovered a little bit of energy, so I smiled and said, "Detective Muda, is this a full sleep?" ”

It's a pity that the answer to me was a big white eye, and he didn't seem to want to joke with me, but after silently making himself a cup of tea, he sat down in the chair with a solemn face, frowned, and fell into deep thought.

"Siyuan, has there been any new news about Zhang Dagui's death in the past two days?" After being silent for a long time, Mu Zihan asked.

"Boss, you haven't received any new news, where will I have it. However, when I was on the phone with Fang Ling yesterday, she told me that from the autopsy, Zhang Dagui was shot through the heart and killed on the spot. For there were no other wounds on his body except the abrasions that might have been inflicted on his own escape. The bullet was also taken out, and it was tested to be the bullet of the common homemade modified Type 64 pistol, but with this alone, it was still like looking for a needle in a haystack to find the murderer. "I didn't expect him to be thinking about that case, in fact, I don't wonder if it's fake, after all, this is very likely to be a case committed by the real "Butterfly Mark", but according to the few clues left at the scene, there is no way to find the murderer.

I still remember the day vividly, and when we arrived at the scene after we heard the gunshots, the scene was already surrounded by hospital staff and patients.

After evacuating the onlookers, Mu Zihan inspected the scene, and he found that in addition to the shot on Zhang Dagui's body, there was another bullet hole left in the ceiling of the bathroom at the scene.

According to Mu Zihan's reasoning based on the situation at the scene, he said that at that time, the "butterfly mark" first used a silencer to cover up the gunshot, killed Zhang Dagui, and then drew the "butterfly" with his blood. Then another shot was fired at the ceiling, deliberately unleashing gunshots to attract everyone to the scene, and then blend in with the crowd of onlookers and flee the scene.

It's just that I didn't expect that in the short time of less than 3 minutes from when we chased down Zhang Dagui to hear the gunshot, he would be able to arrange all this. Because if you count the time when Zhang Dagui ran to the toilet, then the time for his murder was almost only 1-2 minutes. Moreover, did he know that Zhang Dagui would definitely hide in the bathroom on the fourth floor? So I waited there early in the morning, anyway, it all felt unbelievable.

"At that time, if it weren't for the sudden arrival of several emergency calls, a large number of people stormed the blockade at the entrance of the hospital, causing the police blockade arranged by Uncle Wang at the entrance of the hospital to fail. Then we can slowly check all the people who were in the hospital at that time, although it will take a little more time, but according to the reaction of gunpowder smoke and bloodstains, we will definitely be able to catch this cunning 'butterfly'. "I have the heart to comfort Mu Zihan.

"No, Siyuan, you're wrong. The method you mentioned is not realistic, because the hospital is not like a shopping mall, it is impossible to do a long lockdown, and the police cannot delay the treatment of patients in order to find a murderer. Moreover, the smoke reaction and blood stains, these can be disposed of with some techniques. For example, if the pistol is wrapped in a plastic bag before the gun is fired, then there will be no gunsmoke reaction on the murderer. Mu Zihan explained slowly: "Secondly, not to mention in the hospital, even if there are some blood stains on the body, it is not strange. After all, surgical injuries and other people will inevitably have blood stains on their bodies. Therefore, only by sampling one by one and letting Fang Ling conduct DNA comparison can the owner of the bloodstains be confirmed. However, it is also necessary to assume that the murderer is indeed stained with Zhang Dagui's blood, and it will take a long time. ”

"Take 10,000 steps back and say, even if the murderer was indeed stained with Zhang Dagui's blood at that time, if he followed the method you said to investigate slowly one by one, then he would have enough time to dispose of the bloody coat. The easiest way is to corrode the bloodstained part of his coat with a high concentration of hydrogen peroxide, so that even if he finds out that his coat is strange at that time, he will have a reason to excuse it. Moreover, the most important point is that in any hospital, there will never be a shortage of hydrogen peroxide, because the diluted hydrogen peroxide has the function of wound disinfection. Mu Zihan said helplessly: "Actually, compared to this, I am more skeptical that why so many emergency calls came in at the same time, and so many people came to the hospital for treatment, this is the key." ”

However, the police have confirmed with the hospital that those who came to the hospital at that time did need emergency treatment. It seems that their own children have food poisoning, and it is precisely because of this that the police have to lift the blockade. I recalled.

"I know this, I actually investigated this matter in the past two days. That's because of a group of food poisoning among students at an elementary school near the hospital. However, what exactly caused it has not yet been investigated. Because there are many students with food poisoning, but not all of them are found in all grades and classes, it is not possible to eat in the cafeteria. Mu Zihan said thoughtfully: "Is this a deliberate plan or a pure coincidence?" If it's a coincidence, it's too much of a coincidence. ”

"By the way, I almost forgot, what happened to that ghost later? I remember when we came back, he was waiting for us at the door, and then I ended up sleeping and didn't listen to what you talked to him? "I knew that it would not help to talk about that case again, but would be more troublesome, so I deliberately changed the subject.

"Hmph, I didn't talk about anything, I just told him that Zhang Dagui was dead, so that he could leave, don't bother me in the future." After Mu Zihan took a sip of tea, he said angrily.

"He just left so obediently? I remember when he came to you, he was full of resentment! "I didn't expect Mu Zihan to be so angry with this ghost.

"If you don't leave, what else does he want? He himself is not a good thing, he has such a happy family, he is still messing around outside, and he actually has a tryst with his lover at home, and as a result, his own family died tragically with him. If you really want to talk about it, in fact, all the incidents were caused by him, and the other three families were innocently implicated by him. So, after I told him the cause and effect, where would he be embarrassed to stay? As for whether he can let go of this matter, it depends on him, and it has nothing to do with me. Mu Zihan replied very decisively, it seems that he is really unhappy with the ghost of the vice president.
