Wan Zhenghao, a sophomore Chinese teacher who disappeared, is suspected of committing a major crime, he has a motive for killing, he has the time to commit the crime, and most importantly, he is now missing.

Li Meng and I went to Ningzhou No. 9 Senior High School, where Wan Zhenghao worked, to investigate the situation and have a more comprehensive understanding of him.

And Li Meng also mentioned a very key suspicion - Wan Zhenghao's girlfriend died.

It's a very privacy-related question, and I ask, "Is the message reliable?" ”

Li Meng looked at me in a daze, although he was also a little skeptical, but in the end he nodded firmly: "I think it's reliable, this is said by a colleague in the same office with Wan Zhenghao, they have a very good relationship, so they still know each other better." ”

"Wan Zhenghao's girlfriend lives in Ningzhou City, so he will come to work in Ningzhou City after graduation." I muttered a sentence and suddenly asked, "When did his girlfriend die?" How did he die? ”

Wan Zhenghao's colleague said that Wan Zhenghao's girlfriend died last year, it seems that she was in a car accident...... It's like suicide again. How exactly he died, they don't know. Li Meng spread his hands at me, saying that he didn't know very well.

Immediately afterwards, Li Meng added: "In short, the death of my girlfriend hit Wan Zhenghao hard. Wan Zhenghao had a serious illness and was bedridden at home for more than half a month. Since then, Wan has become more reticent. ”

Although we have now identified Wan Zhenghao as the suspect in this serial murder case, I am now even more confused about the motive for this killing.

Wan Zhenghao's motive for killing was because Yu Zhehao and Jiang Zishan had beaten him.

So the question is, why did Yu Zhehao and Jiang Zishan beat him? What is the emotional reason that Wang Zhi said?

The emotional problem is nothing more than the love problem between men and women, could it be that Wan Zhenghao's girlfriend has a relationship with Yu Zhehao and Jiang Zishan?

If you make a bold guess, will the death of Wan Zhenghao's girlfriend have anything to do with Yu Zhehao and Jiang Zishan?

The increase in clues has completely opened my mind, and the clues, which were originally clueless, now have many possibilities.

Just as I was thinking, Li Meng suddenly said: "I think Wan Zhenghao's girlfriend will be the core of this case." ”

"That's right, I was thinking about it just now. It's just that Wan Zhenghao is very upright, and even a little old-fashioned and conservative. So his girlfriend must be a person with a similar personality to Wan Zhenghao, how could such a person have a relationship with Yu Zhehao, a rich second generation who is not doing his job, and Jiang Zishan, a social gangster? "I raised my doubts.

"Sometimes, it's not the pedestrian who crashes the car, it's the car that hits the pedestrian." Li Meng said lightly.

On the surface, this sentence has nothing to do with the case, but the deep meaning in it makes people think deeply.

"You mean, Yu Zhehao and Jiang Zishan took the initiative to provoke Wan Zhenghao's girlfriend, and then let Wan Zhenghao have a conflict with them?!" I said suddenly, then nodded thoughtfully, "It's a possibility." ”

"If you think about it along this line, then the cause of Wan Zhenghao's girlfriend's death is very suspicious." Li Meng looked at me and said in a deep voice.

"It seems that we are now investigating not only Wan Zhenghao, but also Wan Zhenghao's girlfriend and the real cause of his death." After I finished speaking, I asked Li Meng again: "Can you know the time of Wan Zhenghao's girlfriend's death?" She lives in Ningzhou City, and the internal website of the public security system should have information about her death. ”

The exact time of death is not known, but Mr. Wan's colleague said it was early summer. Because Wan Zhenghao was sick in bed for half a month, it was this colleague who substituted for him, so he was more impressed, but the specific time is unknown. Li Meng said slowly.

I nodded and said in a deep voice: "Okay, let's go back to the bureau first, check through the internal website of the public security system, and see if we can find any clues." ”

When he returned to the office of the Serious Crime Team, Xue Hang had just returned, and he had already applied for an arrest warrant for Wan Zhenghao and notified various departments to assist in the investigation.

"Is there any progress on Lin Zifan's investigation of Wan Zhenghao's residence?" I asked.

He just sent a message that he had found the rental house where Wan Zhenghao lived. The search warrant has been applied, and Jiang Tingbai has rushed over with a technical team, and they are ready to investigate Wan Zhenghao's residence. Xue Hang said lightly.

"Did you find Wan Zhenghao?" Li Meng hurriedly asked.

Xue Hang shook his head weakly: "I didn't find Wan Zhenghao." ”

I took a deep breath, calmed down, and said to Xue Hang: "We have investigated some clues in the school where Wan Zhenghao works, but the workload of this clue is very large. Let's find a person who matches Wan Zhenghao's girlfriend among all the death cases in Ningzhou City in the early summer of last year. ”

"Is there a definite time?" Xue Hang asked me.

"Nope." I shook my head.

"Is there a definite cause of death?" Xue Hang continued to ask me.

"Nope." I still shook my head.

"Was it a natural death or an unnatural death?" Xue Hang asked again.

"I don't know." I still shook my head.

Xue Hang looked at me with a helpless expression on his face: "Okay, this is indeed a very heavy task. ”

It's a lot of work, and I can't rely on us alone, so I'm going to go to the Technical Investigation Department and call for some help.

Just when this idea first appeared, Xiao Xuan of the Technical Investigation Department walked into the office.

As soon as he entered the door, Li Meng, I, and Xue Hang all laughed.

Xiao Xuan looked at us inexplicably, but we all have a unique title for calling this kind of person: "wronged head".

"What are you laughing at?" Xiao Xuan looked at us in a daze, subconsciously wiped his face, and looked at his clothes.

"Nothing, are you okay?" I forced a smile and asked him.

Xiao Xuan looked at me, came back to his senses, and said, "We compared the cranial image of Wan Zhenghao based on the frontal photo of Wan Zhenghao and the skull with his back to the man in the physical evidence photo. Because they are all photos, you can only get an approximate result. The results showed that the acquaintance rate between the two was 80%. ”

"Eighty percent, that's enough." After listening to him, I nodded.

Even if it is only eighty percent, it can already be said to be definitive evidence for us. Because in addition to the cranial image, glasses, hairstyle, body shape, and clues we have investigated can all be used as very important evidence to determine identity.
