In the police station, Qi Yong interrogated Song Rui according to the procedures, and Song Rui cooperated quite well and answered all the questions one by one.

Because he is familiar with the law and he really has not killed Gu Chengye, his answer can be said to be in vain and will not give others a chance to attack him.

While being interrogated, Song Rui also obtained a lot of information from Qi Yong.

According to Qi Yong, Gu Chengye and Lu Yue were killed and intentionally disguised as committing suicide by committing suicide after they were killed.

Moreover, the murderer should be very good or professional assassin. Because the murderer's killing methods are neat, Gu Chengye and Lu Yue were both killed by one knife.

Song Rui understands martial arts, and he had had conflicts with Gu Chengye in public, which undoubtedly aggravates his suspicion.

"According to the identification given by the forensic doctor, Gu Chengye and Lu Yue died between 1:00 a.m. today and 3:00 a.m., where are you during this period? Can anyone give you a proof?"

Qi Yong looked at Song Rui and asked another question again.

"I've arrived home at 1:00 a.m. and I went to the living room for about 40. These are my wife and her best friend Sun Lin who can testify to me."

Song Rui recalled it for a moment and replied.

"You said Su Baizhi and Sun Lin can testify to you, but according to their confessions, they were drunk and unconscious when they came home last night and didn't know exactly when they would go home to bed. In other words, they could not make a proof of your absence for you."

Qi Yong looked at the transcript in his hand.

Hearing this, Song Rui suddenly remembered that he had indeed ignored the fact that the two were drunk.

After a moment of contemplation, he spoke again: "Or else you can check the surveillance of our community. I drove back to the community at about one o'clock, and I have never been out since then."

"We have checked the surveillance, but coincidentally, the surveillance system in your community failed yesterday and no video content was recorded at all."

"What's even more coincidental is that when we were investigating the road video, we found that at 2:00 and 3:00 in the morning, a silver van appeared near your community. This van had been to the crime scene at the same time. I wonder what you explained about these two things?"

Qi Yong stared at Song Rui and pointed out two suspicious points again.

Upon hearing this, Song Rui frowned.

He naturally understood that Qi Yong's words were implicit in destruction of evidence of surveillance and destruction.

But using normal thinking to analyze and infer that Qi Yong is right to think so. After all, the surveillance in their community was damaged on the night of Gu Chengye being killed, which is really strange.

Moreover, the suspect vehicle appeared near their community at the crime scene, which made it even more impossible to explain by coincidence.

"Captain Qi, I understand what you mean, but what I want to say is that the damage to the community surveillance has nothing to do with me. I have never been to the crime scene, nor have I killed Gu Chengye and Lu Yue. Please make sure to restore my innocence."

Song Rui said in a deep voice, and he could not think of a reasonable reason to clarify himself for a moment.

"Don't worry, we will never wrongly a good person, but we will never let a bad person go. No matter how deep the murderer is, we will definitely bring him to justice!"

Qi Yong replied with deep meaning.

At this time, he was not sure that Song Rui was the murderer, but Song Rui could not remove the suspicion for the time being.

Just as Qi Yong was about to take Song Rui into custody first and then conduct further investigation into the case, a young policeman walked in.

"Captain Qi, this is the appraisal report just given by the Criminal Investigation Department."

The young policeman said, handing the documents in his hand to Qi Yong.

Qi Yong glanced at Song Rui with a sharp look.

"Song Rui, we found half a fingerprint on the murder weapon left at the crime scene. According to technical identification, the fingerprint belongs to you. In addition, our colleagues in the criminal investigation also found a button on the scene. After identification, they were completely consistent with the button on the shirt you wore last night. Now the evidence is as strong as a mountain, how can you make a judgment!"

Qi was brave and powerful, and he was the first to win the way.

Originally, Song Rui was very suspicious, but now two more crimes have been added, almost confirming Song Rui's murder.

When Song Rui heard this, he felt a deep heart.

"Captain Qi, can you let me see if the murder weapon has the button?"

Song Rui asked.

"The evidence is in the evidence department, and I can only let you see the photos now."

Qi Yong replied, and then took the documents in his hand to Song Rui.

"This is a photo of the murder weapon, this is a photo of the button, these are identification reports."

Qi Yong placed the photos and documents in front of Song Rui and explained them one by one.

Song Rui stared at the photo for a moment, then looked up at Qi Yong.

"Captain Qi, Gu Chengye wanted to kill me with this knife last night, but the knife was taken off by me, so it is normal for me to have my fingerprint on the knife. If you don't believe it, you can go to Wanfu Bar for verification. Many people saw it when he committed the crime last night."

Song Rui pointed to the murder weapon photo and explained that the photo showed the switchblade that Gu Chengye took out of the car yesterday.

"Then how do you explain this button? We found this button in the palm of Gu Chengye's hand. He should have pulled it off the murderer's clothes before he died."

Qi Yong picked up the button and continued to ask.

"This button was probably pulled off at the entrance of Qianye Bar last night. After we left Wanfu Bar, Sun Lin was too sad because Gu Chengye cheated, so we went to Qianye Bar again."

"But when we left there, a gangster attacked me. We were paying attention. When I got home, I found that one of the buttons on my shirt had been pulled off. I guess this should be the murderer who deliberately put it in Gu Chengye's hands, intending to frame me, and please make sure to investigate it clearly."

Last night, Song Rui felt strange. The gangster who attacked him was quick and did not seem to be an ordinary person, but he immediately ran away after being kicked by him.

Now he finally understood that the man was not a gangster at all. He provoked him just to fight him, and then he pulled the buttons off his body while he was unprepared and framed him!

Although it seems to be insignificant, it is precisely the other party’s cleverness!

After all, the entire murder scene was disguised as suicide for love. According to common sense, the murderer would definitely clean up the evidence of the scene to destroy the crime, and half of the fingerprint and one button would become evidence that the murderer accidentally "missed". In this way, these evidences would become more convincing!

After hearing Song Rui's explanation, Qi Yong, who had already designated Song Rui as the real murderer, couldn't help but feel shaken in his heart.

If what Song Rui said was true, then the real murderer could have taken great pains. After all, it is quite difficult to frame Song Rui in such a situation.

But at present, this is just a one-sided statement from Song Rui.
