In the original interrogation room, Xylophone looked at the student ID card in front of him, obviously not knowing what was going on.

"You say, I killed someone?!" After a long time, she looked up in disbelief at the two interrogating officers, her voice trembling and fearful.

The two police officers glanced at each other and nodded, anyone who learned that someone who had crossed paths with him in the morning would have such a reaction when he died before the day had passed, not to mention that this kind of thing had something to do with him, the reaction of the girl in front of him was really normal in the end, but it was the young man's calm reaction before that he was like a murderer.

"It seems that it has nothing to do with it, but where did this student ID come from?" In another interrogation room, Mu Du listened to Li Zhishi's detailed description of their day, and determined that the young man with a good memory and his female companion had nothing to do with the murder.

Hearing Mu Dui's muttering, a figure suddenly appeared in Li Zhishi's mind, but he thought about it for a long time, but finally shook his head.

If the motive for the murder is concerned, it is indeed that the pair of sisters are seriously suspected, and the girl named Su Nian does have the opportunity to take away the xylophone student ID.

But the other party doesn't have to blame the xylophone after killing? According to the clues that the police have now revealed, most of the places where the man was killed were that there were no traces left by the murderer other than the student ID, indicating that the murderer's act of dropping the student ID card was completely redundant.

"Is it used to interfere with the judgment of the police and involve energy?" Li Zhishi nodded thoughtfully, he really couldn't find any other suitable explanation.

At this time, Mu Du also repeated the murder that happened under their noses again in his heart, and came to the same conclusion as Li Zhishi, and then the two looked up at each other at the same time.

"Officer Mudu figured it out?" Li Zhishi was the first to ask, he didn't want to be looked at like a prisoner here anymore, even if he did, the xylophone who was also being interrogated alone over there might not be able to stand it, so he had to find a way to quickly remove the suspicion of the two of them.

Mu Dui's eyes narrowed at Li Zhishi's question, obviously surprised that the young man in front of him could still think clearly and judge the situation in such a situation, but when he thought of the other party's memory beyond ordinary people, he felt that it was not so difficult to accept.

Seeing that Mu Du was silent, Li Zhishi frowned and said: "Since you can understand that this matter has nothing to do with us, can you let us go back and interrogate us overnight like prisoners, I can stand it as a man, but my friend is a female college student who is ignorant of the world." ”

Li Zhishi's slight impatience fell in Mu Dui's eyes, and when he realized that this young man was not really unfazed, he couldn't help but feel a sense of relief.

"Actually, if it weren't for your alibi, I'd have suspected that you did it." After Li Zhishi's questioning, Mu Duan replied abruptly, and then smiled lightly and waved his hand in the latter's equally narrowed eyes, "Okay young man, take your girlfriend back, by the way, do you want me to embarrass your companion over there, and then let you go to the hero to save the beauty again?" I checked, you actually opened two rooms, tsk, it's almost Tanabata, so I, a person who came over, couldn't bear it. ”

"Thank you for your kindness, forget it." The corners of Li Zhishi's mouth twitched, the police officer in front of him really subverted his impression of the police profession.

"It's a pity." Hearing Li Zhishi's refusal, Mu Du shook his head with a pout, and only after looking at the former's back and leaving the interrogation room without hesitation did his expression become serious again, and the news that suddenly came from the headset made him feel that he was becoming more and more unable to understand the case.

When Li Zhishi came out of the police station with the xylophone, it was already close to the early morning, and the two took a taxi back to the hotel and then went back to their rooms to rest.

But not long after he fell asleep, there was a knock at the door, and when he opened the door, he found that it was a xylophone in pajamas standing at the door, looking at him pitifully.

"Well, can you sleep on the couch? I'm afraid. ”

When Li Zhishi lay on the sofa without understanding the situation at all, carefully analyzed his inner fluctuations, and found that there was indeed no idea of separation, he closed his eyes peacefully, but he naturally felt a little regretful in his heart.

"If you knew that you would have opened a room, wouldn't it be a waste of money......"

……

……

It was probably a long, but not difficult, night for Li Zhishi, but for some, it was a complete sleepless night.

After Li Zhishi left, in the police station, Mu Du started to act after holding a small meeting with the members of the task force, since the suspicion of Li Zhishi and the two was ruled out, then their remaining targets were actually only the other two - the pair of sisters.

And the reason why Mu Du was sure of the arrest operation was that when Li Zhishi pushed the door out, the news from the front-line police through the headset came.

Not only could they not be contacted, but from the time of the incident to the present, they could not find any check-in and consumption information of the sisters in the city.

The only thing that can be known is that the news was obtained not long ago, the two sisters once appeared around an urban village in the city, and then the surrounding surveillance has not monitored their figures, although I feel that this case is always unspeakably strange, but after learning the news, Mu Dui finally chose to attack.

Some reporters have learned about this case through unknown channels, and it is estimated that tomorrow the major newspapers and media will publish news such as "the dereliction of duty of the city police officer led to the death/death of the prisoner", so they are really passive.

Soon the police of the city bureau set up a tight cordon at the exits of the urban village, and then several teams of police officers rushed in and carried out a silent search in the early hours of the night.

"Sister, what should I do......" In a private house, looking at the approaching police search team outside the window, Su Nian hugged Su Yu's arm with a frightened face, and the latter's eyes also showed a touch of helplessness and coldness.

When she learned that there was no substantial evidence to convict the man, she did have the intention to kill, and with her skills, she could indeed kill him in that situation, and she did it, but when she arrived, she found that the man had just died before he came.

Someone, before her, was the first to kill someone!
