What I never expected was that the murderer turned out to be Yao Xun'an?!

What was his motive for killing? Du Qin, Xu Kuan, and Hu Yuanling are all his junior high school classmates, what kind of grievances made him complete such a shocking case?

Three lives were killed by him, is this serial murder case really coming to an end?

In the interrogation room of the criminal police team of the Ningzhou Public Security Bureau, Yao Xunan sat on the "regret chair", but he did not regret it at all now, because he did not admit his guilt at all.

"I didn't kill anyone!"

No matter how much we ask, that's what he said.

In the face of ironclad evidence, it doesn't matter whether the murderer pleads guilty or not, and it can't change the status quo. But such a premise is that the chain of evidence is closed, but we are missing the most critical motive for killing.

"I didn't kill anyone!"

Yao Xun'an pulled his neck and continued to roar.

"You didn't kill anyone? I think you're killing a lot! Officer Wang sat in the interrogation room and said quietly.

"I didn't kill anyone!"

Yao Xun'an has been saying this sentence from beginning to end, refusing to admit the accusation of murder.

"You didn't kill anyone? Why are there your footprints and fingerprints at the scene of the crime?! Officer Wang also raised his voice and shouted at Yao Xun'an.

"What crime scene, if you don't tell me, I don't even know that there are dead people!" Yao Xun'an sneered and said seriously.

"Well, since you don't admit it, then you can explain to me why we found your fingerprints and footprints in Hu Yuanling's house. You'd better think about it and give me a convincing reason. Officer Wang leaned back in his chair and stared at him and said that he was ready for a long fight.

Yao Xun'an looked at Officer Wang's appearance and said helplessly: "I admit that I have been to Hu Yuanling's house, but I definitely did not kill her. ”

"When did you go to Hu Yuanling's house? What to do? When Officer Wang saw that he had finally opened his mouth to talk about the case, he immediately asked.

Hearing this question, Yao Xun'an's attitude weakened obviously, but he didn't say anything for a long time.

"What? Don't have a good idea of how to make it up? Officer Wang looked at him disdainfully and said with a sneer.

Yao Xun'an looked at Officer Wang's playful expression, gritted his teeth, stomped his feet, sighed and said, "Alas, I'll tell you the truth, after the class reunion, I went to look for her one day." ”

"Oh? What are you going to do with Hu Yuanling? Officer Wang was still full of disbelief, and now he wanted to see where this Yao Xun'an could go.

"I'm going to find her...... Look for her to see if you can continue the front edge......" Yao Xun'an muttered a little weakly.

Of course, Officer Wang knows Yao Xun'an's humanity, what bullshit is to continue the frontier, it is nothing more than to fight for a night of warmth, and then leave Ningzhou City and go home as if nothing happened.

"And then?" Officer Wang stared at him and asked.

"Then as soon as I entered the door, Hu Yuanling blasted me out, and I didn't even enter the living room." Yao Xun'an shrugged his shoulders a little helplessly, as if he was still immersed in the loss of his failure to continue the front edge.

But now, Officer Wang couldn't laugh, because Yao Xun'an's description was exactly the same as the situation of the police investigation at the scene, and it also matched the area where fingerprints and footprints were found at the scene.

Now Yao Xunan refuses to admit his guilt, and the criminal police team also conducted a careful investigation at Yao Xunan's home, but found no clues.

At present, the police have no direct evidence to accuse Yao Xunan of murder, and according to the principle of suspicion without evidence, we can only detain Yao Xunan for 48 hours at most.

Officer Wang told me about the interrogation, and I was in a dilemma.

If Yao Xun'an is really not the murderer, it means that our method of comparing footprints and fingerprints to find suspects is fundamentally wrong, and we must stop the current case investigation work and start all over again.

"Let Yao Xun'an go back, send someone to closely monitor him 24 hours a day, he is the ticket to leave Ningzhou City the day after tomorrow, even if he is not the murderer, he will definitely be the murderer's next target. We must watch him for the past two days, and while waiting for the rabbit, we must protect his safety! I thought about it for a long time and said to Officer Wang.

"Just let him go? He hasn't cleared his name yet. Officer Wang was a little hesitant and felt that something was wrong with this matter.

"Even if we don't let him go back, we can only lock him up for forty-eight hours, rather than let him stay here for forty-eight hours and then let him go, it's better to let him leave us and see if we can follow him to find some clues." I thought about it and said.

"Okay, I'll send someone to follow him." Officer Wang thought about it, was persuaded by me, and turned around and went to handle the matter of releasing people and sending people to monitor them.

"What now?" Li Meng was a little overwhelmed.

Because with the release of Yao Xun'an, it is announced that the direction of our case investigation is wrong, and we are faced with the reality of overturning everything and reproducing the investigation.

But at least one thing will not change, that is, the murderer must be among the twenty-eight people attending the class reunion.

"The 28 people were re-investigated, and although there were no fingerprints and footprints for comparison, Jiang Tingbai said that the person found on the rooftop was a size 42 shoe, and through the identification of footprints, there was no such thing as big feet wearing small shoes or small feet wearing big shoes." I took a deep breath and said lightly.

"So, you're going to arrest all of the twenty-eight people who wore size forty-two shoes?" Li Meng looked at me in surprise.

"It's not to arrest it, it's to list it as a key suspect for investigation. That's the only way to do it at the moment. I said seriously.

The murderer attended a class reunion, wore size 42 shoes, had access to highly corrosive sulfate chemicals, and had a grudge against the "Seven Dragons and One Phoenix" school bullying gang.

Eight of the twenty-eight were women, and in addition to the three deceased, there were seventeen remaining, of whom there were eight people wearing size 42 shoes, including Yao Xun'an and Chu Ming.

At this moment, the criminal police team received a report that another homicide occurred in Ningzhou City.

The deceased was a woman who died at home and it was her husband who called the police.

The husband went out fishing, and when he came home, he found his wife dead at home, so he called the police.

"There is a criminal case, you take the criminal police team to investigate, what are you doing with me?" I was very puzzled by Officer Wang's police report.

"The deceased's name is Liu Huiqin, and she is a teacher at Ningzhou No. 1 Experimental Middle School." Officer Wang said a piece of news that shocked me.

"What? Teacher Liu is dead?! ”

Teacher Liu's death was something I never expected......
