"What?!!" Zhou Yan almost jumped up: "You... can you be sure?"

"Of course," Xiao Chen said: "When we took Zhang San to the police station this morning, we had extracted the DNA. We had already done the comparison just now, and it was 100% impossible to make a mistake."

"Can DNA comparison be made so quickly?"

"Normally, it should take 24 hours, but the basic comparison only takes 10 minutes. The rest of the time is used to eliminate other interference items... and Zhang San...

Judging from the situation of this case, it must be his and he didn't run away."

"Okay..." Zhou Yan nodded.

"Also, we were still finding fingerprints on the fire box where we installed the axe, and it was also Zhang San's." Xiao Chen said again.

"Damn it?! There are fingerprints on the fire box?"

Zhou Yan is really useless. The evidence is simply clear. Zhang San is the murderer.

"Okay, if there are any other discoveries, let me know as soon as possible."

"OK."

After saying that, Xiao Chen walked back to the crowd.

Zhou Yan picked up the phone again and just put it on his ear, he heard the third brother shouting opposite him: "What's wrong? What's wrong?"

"Uh..." Zhou Yan hesitated for a moment: "That third brother, if you don't tell me what happened to the towel, you'll just wait to be shot." "???" Zhang San was stunned.

I said: "Why am I going to be shot? I really didn't kill anyone. Besides, didn't you just say that you were trying to get life imprisonment?"

"Life imprisonment means that you just killed someone, raped him first and then killed him...then you must be shot and ran away!"

"Raising first and then killing?" The third brother was also confused: "Why did he come out and rape first and then killing again?!"

"DNA!" Zhou Yan explained: "The police detected your DNA on the deceased's head."

“DNA?”

"Yes, it's actually your tadpole!"

"..." The third brother was stunned all of a sudden. He naturally understood what [tadpole] was, so, after a second: "It's impossible! I just took a plane, how could I run away?

Go to the head of the deceased!”

"Make a plane?" Zhou Yan directly grasped the point: "What did you use to hit, your hands? Or something else."

Alas, let’s talk about it. It’s really embarrassing to discuss such things in front of others, especially two big men. Oh, by the way, there are a group of policemen around Zhang San.

But under this situation, it is impossible not to discuss it.

Zhang San gritted his teeth: "I...the towel I used."

"Is it just a hotel towel?" Zhou Yan asked again.

"Yes." Zhang San replied: "I also applied a thick layer of moisturizer on it, which is also from a hotel."

Zhang San said, and the police in the circle next to him listened, "Oh, our third brother feels that he is about to die in society."

"Then what if you finished the plane?" Zhou Yan tried harder and continued to ask.

Zhang San’s face is really impossible to take, but his life is important, so he can only answer: “I hid the towel in the fire box.”

“Fire box?”

"Yes." The third brother replied: "I finished urinating. The towel was moisturized and mine... Ahem, I can't take it anyway. I think it's just that.

It was really disgusting when I put it in the room. The cleaning person found out that I might have to deduct dozens of dollars of towels.

So, I simply wanted to hide the towel.

After that, I left the house and found a fire box in the stairwell.

I quickly stuffed the towel inside."

Brother Zhang said so.

Although it is embarrassing, these words can really relieve Brother Zhang San's suspicion.

Then... this towel was stuffed into the fire box, and the murderer could naturally take the towel away when he took the fire axe.

Zhou Yan sorted out the brain circuit in his mind a little, and said to his phone: "Okay, these testimonies are enough. If you really didn't kill someone, I promise that no one can wrong you, and no one will

Can be blamed for you."

After Zhou Yan finished speaking, a series of words of perception came from the other side of the phone, but Zhou Yan had no time to listen and hung up the phone.

Now that the tadpole problem has been solved, we will return to the initial questions of the case.

Who is the murderer?

What method did the murderer use to cut off the dead man's head in the elevator.

Zhou Yan closed his eyes and thought for a while, but found that he still had no clue, so he had to open the book again.

I left too many messages before, and he hasn't finished reading it yet, so I'll continue reading it now.

[I still ■■: Go to Hu Yitong, the most uncontradictory thing about all this is Hu Yitong.

But if Zhang San really threw away the towel after using it, the one who might get the towel at will in the end would be Hu Yitong, who acted as a hotel cleaning company.

Moreover, by taking advantage of the reason for cleaning the room, you can enter and exit each room without any sense of incongruity, which has a prerequisite.

However, I haven't figured out how to cut off the head directly in a short period of time. In short, our principle is to boldly assume and carefully verify it, and investigate Hu Yitong's social background]

"Well... Indeed, if it were Hu Yitong, his conditions for committing crimes were sufficient, because he could enter and exit any room at will, but this killing method was really difficult to deal with."

【20171101185545412: Why is the key?】

"Why? What's the why?" Zhou Yan frowned: "Is he asking why the murderer was beheaded? Of course it was to kill the dead...wait!"

Suddenly, Zhou Yan was stunned for a moment.

Yes, why do you need to cut off your head?

If it is just to kill the dead, there are other ways.

Why do you have to find an axe?

You also have to cut off the other party’s head? You know, beheading is not an easy task!

Moreover, judging from the murderer's busy work, it is obvious that he has a certain amount of preparation time. So since that is the case, he has every time to buy something like a knife.

This is convenient and easy to carry. Posing it into the neck is not much easier than slashing an axe, and it is not slow to die.

So...why do the deceased have to use an extremely inappropriate [axe]?

The head is also... why should I throw it on the roof of the opposite building?

What else can I do if I put it in the elevator? Are you still afraid that the deceased will point out the murderer?

Could it be that the murderer knew what was the sticky thing on the towel, so he had to do so many things to blame his third brother?

It's not right. If you want to blame the problem, just rub the things on the towel on the deceased, and you don't have to chop your head.

Zhou Yan just thought about it, thinking... Gradually, his stiff mind seemed to have thought of something.

At the same time, he also noticed a message on his notes...
