However, it is estimated that seeing that our faces are also full of doubt and disbelief, Mu Zihan finally opened his mouth and began to explain. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Actually, when I saw the location of Director Lu's office, I had already positioned him as one of the suspects in my heart." Mu Zihan said helplessly.

"Why?" I couldn't help but ask. I really didn't expect this, it turned out that Mu Zihan was already suspicious of Director Lu so early.

The reason for this is simple, his office is located on the innermost part of the third floor. And next to the stairs to the rooftop of the building. Therefore, if you want to go to the rooftop without knowing it, there is no more convenient than him. On the other hand, if someone wants to go to the roof, they have to pass through his office. Mu Zihan replied: "Although, I didn't know the method of this case at that time, but, Siyuan, you shouldn't have forgotten that not long ago, Lin Shixuan came to ask me about the strange things in the detention center in the past few days, so of course I will pay special attention." ”

"Oh, I see. But in this case, when discussing the action plan with Lin Shixuan and Fei Yiping just now, why didn't you bring it up for Director Lu to recuse himself? I suddenly said, "Aren't you afraid that he will reveal this to the 'Butterfly' organization?" Or are you so sure? I'm going to solve the case tonight. ”

However, after I told Mu Zihan these questions, instead of answering me immediately, he laughed.

It wasn't until I was so depressed by his laughter that he restrained a little, but still said with a smile: "Siyuan, do you think of me too much?" I'm not a god, how can I know so much? Actually, although I was suspicious of Director Lu at the time, but just with a little suspicion, what qualifications do I have to let a dignified detention center director recuse myself? It's just that, judging from the current situation, it's fortunate that he didn't let him avoid it, otherwise how could he expose the fox's tail by himself? ”

As he spoke, he began to tell the story of his step-by-step process of completely determining that the murderer was Director Lu. It turned out that in fact, when he saw the location of Director Lu's office, he only secretly classified Director Lu as a suspect in his heart.

Later, when all the murderer's murder methods were determined in the cell at the scene of the crime, he knew that the murderer had used the roof of the building, and he aggravated Director Lu's suspicion in his heart.

However, later, when he heard the thin prison guard say that he watched Director Lu drive away with his own eyes, and came to such an alibi, Mu Zihan ruled out the suspicion that Director Lu was the murderer.

It's just that when I checked the surveillance camera, I found that there was a very important surveillance camera, although it was naturally damaged, but it had been several days, why was it not repaired?

You must know that the surveillance cameras in the detention center are not like the cameras in some shopping malls, many of them are only used for deterrence and decoration. Cameras in detention centers do have their indispensable functions, and once they fail, they are generally repaired as soon as they occur. Even, at every fixed period of time, someone will come to carry out maintenance checks.

Therefore, if the surveillance camera used to monitor the cell in the detention center fails for two or three days and is not repaired, someone must be secretly delaying. So why would this man do such a thing? Combined with the methods of today's murderer, the answer can be imagined, it is to facilitate today's crime.

And in this detention center, although there will not be only Director Lu, there will not be too many people who can do this. Therefore, Mu Zihan once again included Director Lu in the list of suspects.

In addition, although Director Lu seems to have an alibi, like such a remote detention center, there is still a mountain road along the road that is not long or short, so many sections of the road are not installed with road monitoring at all. Therefore, even if the prison guard said that he watched Director Lu drive away from the detention center, who can guarantee that he must have gone home, not sneaked back to commit murder after going around in a circle?

Especially when Mu Zihan expressed doubts about the monitoring, Director Lu seemed to be very far-fetched to bring up the situation at the back door of the detention center. Although, after arriving at the back door, I did see signs of malicious vandalism in the old back door lock located in the weeds.

But if you think about it from another angle, this is actually not self-admitting. After all, if it is an outsider, how can it be so simple to sneak into the detention center? Do you still know so much about the structure and situation in the detention center?

"It is estimated that even some of the suspects who have served their sentences in this detention center cannot be so clear about the structure of this detention center. It is only the staff who have been in this detention center for many years, and those who still work here, that they know so much about this. Mu Zihan smiled and looked at Director Lu, who was speechless, and said.

Seeing that Director Lu still didn't react, he continued: "Next, combined with the time period when the key to the cell at the scene of the crime was stolen and secretly put back, Director Lu also entered and exited the duty room where the key was stored. This is all the more certain. In the end, there are the large footprints, which are too fake and too fake. ”

"The footprints are so big and so deep, Director Lu, do you want us to suspect that it was the 'Hulk' who infiltrated the detention center and killed Zhang Cheng?" Mu Zihan said with a mocking smile: "Combined with the above inferences, then, the result is obvious, it is estimated that even if you ask the prison guards to help take down the car key, it is just to create an alibi for yourself." So, in the end, as soon as I borrowed the car and tried it, everything was clear. ”

With Mu Zihan's narration, I also recalled our experience tonight step by step in my mind, and finally completely figured out his entire process of solving the case. It's just that it also reminds me of a question that we haven't found an answer to until now in terms of modus operandi.

"By the way, speaking of autopsy, Zihan, do you remember the scratches on Zhang Cheng's neck? Is it really that coincidental? Was it when Director Lu strangled him that he woke up? I asked.

"No, Siyuan, those were actually before Director Lu put the rope hanging down from the top floor around Zhang Cheng's neck. Taking advantage of Zhang Cheng's stunned by him with Ge Luofang, he grabbed Zhang Cheng's hand and scratched it. This is to make us mistakenly believe that the deceased was awake at the time of the murderer's murder. Mu Zihan explained: "This is to mislead us into reasoning about the modus operandi. ”

It's a pity that Director Lu doesn't seem to be very familiar with Ge Luofang's effect on the human body and the control of the dose, in order to make sure that Zhang Cheng will not wake up before he does it, he used too much amount. As a result, during the autopsy, a slight sweet smell peculiar to Gorofang could be smelled between the mouth and nose of the deceased. Mu Zihan explained.
