"Hey..." Mu Zihan looked at me with a look of hatred for iron and steel, shook his head and sighed, and then pointed to a few books scattered not far from his feet and said, "Don't you notice that these books are different from other books?" ”

I stepped forward to pick up the books that seemed to be stained with blood stains he was pointing to, and after reading them carefully, I said, "Except that there are more blood stains, and the paper inside is a little wrinkled because of the absorption of blood, there is no difference?" Don't tell me that the content is different, but the thickness and number of pages are different. Pen %Fun %Pavilion www.biquge.info"

"Do you think I'm you? It's going to be so boring, pig. Mu Zihan looked helpless and angry and said: "Siyuan, in fact, you have already discovered their abnormalities, but in your mind, it is natural to normalize them again, thinking that they should be like this." Therefore, you will unconsciously give up and continue to think deeply, not thinking about why they are the way they are, and ignoring the clues hidden behind them. ”

Mu Zihan's words seem to be very plain, but after serious experience, they have a deep meaning. Isn't that what most people do? Because they always self-righteously normalize what they see, without going back to the root cause and looking for the real cause, they tend to ignore many important things.

Seeing that I didn't answer, he began to explain: "First of all, we already know the order in which the murderer committed the crime. He attacked Inspector Chu Hengyu first, and then deliberately knocked down the bookshelf, disguised as an accident. It stands to reason, then, that at most, these books can only be stained with a little blood that splattered around when the murderer committed the crime. ”

"Second, although the back of the human brain is important, it is not like other parts of the body, which will bleed a lot of blood after being attacked. Moreover, although Chu Hengyu has short hair, he can absorb and hinder some of the blood that seeps out of the wound, so it is impossible to have enough to make several books stained with blood. ”

"Third, the blood stains on these books are so light in color, so they must have been mixed with other liquids and diluted."

"Fourth, there is obviously some distance between the position where these books fell on the ground and the position of Inspector Chu Hengyu's head on the ground, but there is no other blood stain between the two, so it is absolutely impossible that the blood that flowed from Chu Hengyu's wound flowed to these books again."

"Fifth, although the paper of these books is basically dry, it is a little deformed from the corners, and it is not difficult to see that they have been damp before."

"Based on the above five points, then Siyuan, may I ask what is it, which is originally solid and has a certain hardness, which can be used to injure the back of the human head; After that, it can be turned into a liquid, diluting the blood, or more precisely, diluting the blood that sticks to it, so that it can be absorbed by the paper on the book; In the end, it can disappear without a trace, like air? After Mu Zihan finished counting, he turned to look at me and asked.

"Ice." I replied with a wry smile.

In fact, when Mu Zihan counted to the third point, I had already deduced that the murder weapon was an ice cube. Yes, it's because it's an ice cube that it can both transform and disappear. And because it was ice, it had already evaporated in the air now, so Mu Zihan said that he didn't need to look for it. After all, the original murder weapon "ice cube", which has been turned into water vapor and dissipated into the air, is impossible to find even if the police officers of the Evidence Collection Bureau are powerful.

"I see, I really don't need to look for it. However, in this way, there is another lack of key evidence. Hey..."At this time, Fang Ling interjected a little frustratedly, but then she changed the topic and asked: "By the way, Zihan, you said before that you wanted to find out the suspect, do you already have a clue?" ”

It can be seen that she is different from me, although she is also very concerned about the murderer's modus operandi and murder weapon, but she is obviously more concerned about who the murderer is.

"That's right, the clue is in Inspector Chu Hengyu's mobile phone. Didn't you find him at the same time that you found his cell phone? Mu Zihan replied: "Then you can find out from his call records that on the day of the crime, that is, yesterday, the murderer should be among the people who talked to him." Then use the alibi to rule out the possibility of these suspects committing the crime one by one, so that even if it is impossible to find the only suspect at once, at least the scope can be greatly narrowed. ”

"Oh, I see. But how did you know that they found his phone in Inspector Chu's hand, not in his pocket, or somewhere else? And why is it said that the murderer and him are on the phone? In addition, in order to use an alibi to rule out suspicion, it is first necessary to determine a relatively accurate time of the crime, which cannot be set from 8 p.m. to 2 a.m., such a large time span as a mark. If that's the case, then it is estimated that most people will not be able to come up with a complete alibi for this time period. Fang Ling asked suspiciously.

Hearing Fang Ling's question, I couldn't help but smile secretly, because these are also what I want to ask, but now that she has already asked for me, then I will save trouble, just sit back and wait for Mu Zihan to answer.

However, Mu Zihan was depressed, and he scratched his head helplessly and said, "Forensic Doctor Fang, why are you like a curious baby, I thought that Siyuan would have so many problems." Okay, so I'll give you a simple answer. ”

As he spoke, he was silent for a while before he spoke again: "First of all, why do I know that the phone is in his hand? That's because I speculate that the strange call to the police around 12 o'clock was made by himself, otherwise it would be impossible to explain that someone would have called the police on his mobile phone at that time. ”

Mu Zihan said: "I think he should have woken up at that time, but unfortunately because his body was pressed by the bookcase and the back of his head was concussed, he couldn't last long, so he could only barely take out his mobile phone from his pocket, use the emergency call, dial the police, and then fell into a coma again." ”

After Fang Ling and I nodded in understanding, he continued: "As for why the murderer spoke with him on the phone, the reason is also very simple. As I said before, from all the indications at the scene of the crime, it is very likely that this case was committed by an acquaintance of Inspector Chu Hengyu. ”

Saying that, Mu Zihan paused for a moment, and then said thoughtfully: "Moreover, from the modus operandi I just knew, it can also be seen that if it weren't for the people who often come to visit Chu Hengyu in this house, they wouldn't have been able to think of this modus operandi at all, especially the way to leave this house." ”

"Moreover, it can be inferred from the fact that the murder weapon is an ice cube that this is a premeditated and deliberate murder, and Inspector Chu Hengyu usually spends most of his time in the police station, so if you want to meet him in this house, then you must contact him by phone in advance." In the end, Mu Zihan answered in one breath, and began to lower his head again thoughtfully, and he didn't know what he had found again.

"Oh, I see." Fang Ling thought for a moment and nodded. probably felt that what Mu Zihan said made sense, so he immediately asked the last and most critical question: "What about the time of the crime?" ”
