Chapter 598： new discovery

.

Regarding Luan Dongtian's interrogation, Chen Yan had very limited information.

The information provided by Luan Dongtian only explained how he and Duan Lanzhi got to know each other and got together, and explained why Duan Lanzhi did not take public transportation on May 26.

The two traveled to Tibet by themselves and did not return to Liancheng until June 15.

But the second time Luan Dongtian met Duan Lanzhi was on June 20th, and Duan Lanzhi had already disappeared on June 20th.

This means that Duan Lanzhi should have been killed between June 15 and June 20.

However, Luan Dongtian himself did not clear up the suspicion of killing Duan Lanzhi. The surveillance video at that time had been overwritten, and there was no way to investigate it. Of course, Luan Dongtian said what he did.

Although it is unlikely that Luan Dongtian killed Duan Lanzhi in terms of the motive of committing the crime, it is also possible that Luan Dongtian finally killed Duan Lanzhi in order to prevent Wang Shuang from finding out what happened between him and Duan Lanzhi.

Of course, it is not certain that the murderer who killed Duan Lanzhi was Luan Dongtian. Just as Luan Dongtian could not prove that he was not the murderer, Chen Yan and the others did not have conclusive evidence that Luan Dongtian was the murderer.

There is no doubt.

In the conference room, Chen Yan and others are having a meeting.

Wu Zhiguo took a puff of his cigarette and patted the table: "I personally think that Luan Dongtian is the murderer."

"Think about it, first, from the clues we have now, the person who saw Duan Lanzhi for the last time was this Luan Dongtian, who picked up Duan Lanzhi from Sichuan Province by car on May 26. , and then returned to Liancheng after a self-driving tour in Tibet Province, and then Duan Lanzhi disappeared completely. He said that on June 20, he went to the Shanhe Jiayuan Community again, but he did not see Duan Lanzhi. Who can prove it?"

"Secondly, in terms of motivation, although he has been with Duan Lanzhi for a long time, because of Luan Dongtian's business failure, the main financial supporter of his family has changed from Luan Dongtian to Wang Shuang, so his family status in the family has changed. Before Luan Dongdong's business failed, he wasn't afraid that Wang Shuang would find out about his affair with Duan Lanzhi, but what about now?"

"I think both the motive of the crime and the clues discovered so far point to Luan Dongtian as the murderer."

Liu Qingshan nodded: "I agree with Captain Wu's opinion. Although we haven't found any evidence that Luan Dongtian directly killed Duan Lanzhi, as Captain Wu said, the last person Duan Lanzhi saw before he disappeared should be Luan. East Day."

"As for accidental death like seeking money, the possibility of death is not high. In the room where Duan Lanzhi lived, more than 100,000 yuan in cash was found but not lost. There are also some gold and silver jewelry. The possibility of acquaintance committing the crime is the greatest. .”

Chen Yan actually agrees with the judgments of Liu Qingshan and Wu Zhiguo. Judging from the current clues, Luan Dongtian's suspicion is obviously the biggest.

But to determine Luan Dongtian's guilt, direct evidence is needed, and without evidence, it is useless to say anything. In addition, there is another question, that is, if Luan Dongtian is really the murderer, why didn't he report his disappearance?

If it was Luan Dongtian who dumped Duan Lanzhi's body into the water storage tank, then he should know that no matter how long this matter has not been discovered, it will eventually be exposed, because the body will not disappear without reason. Although Luan Dongtian didn't necessarily know that the waxing of corpses existed, the corpses could be preserved well, but even rotting would leave bones.

What's more, if the corpse is thrown in the water storage tank, once the corpse decomposes, it will be quickly discovered by the residents.

In other words, if the murderer really wanted to hide Duan Lanzhi's body, then he shouldn't have thrown the body into the water storage tank.

Because Duan Lanzhi lives in Luan Dongtian's house, it is impossible to hide this matter.

Even if it can be concealed, Luan Dongtian should clean up the house, otherwise, isn't he deliberately leaving clues for the detectives?

Chen Yan uttered his question, and everyone frowned. This was obviously a suspicious point.

"Also, there's one thing we all overlooked."

Um?

"What's up?"

Chen Yan stood up, operated the projector, and the

.

It is Duan Lanzhi's character relationship map: "Since Duan Lanzhi has been dead for more than 3 months, why didn't people from her hometown in Sichuan Province call the police?"

"The first time Duan Lanzhi was missing was reported to the police by Wang Shuang, the owner of Tingmei Beauty Club. Afterwards, we contacted Duan Lanzhi in Duan Lanzhi's hometown in Sichuan Province, and knew that she returned to Sichuan Province from Liancheng."

"Actually, there is a question here, that is why Duan Lanzhi suddenly returned to her hometown. Given her relationship with Wang Shuang, is it necessary to leave without saying goodbye, let alone Luan Dongtian's relationship."

"In addition, after Duan Lanzhi left his hometown, Luan Dongtian drove there to pick him up, and then the two went to XZ together, and then returned to Liancheng. When Luan Dongtian went to Shanhe Jiayuan on June 20, Duan Lanzhi disappeared."

"Until now, for more than three months, the beauty salon didn't call the police to explain, because they didn't know that Duan Lanzhi had returned to Liancheng, but what about Duan Lanzhi's family?"

"You know, she still has her husband and child in Sichuan Province, and she hasn't been contacted for three months. Why didn't they call the police?"

"Yup!"

Wu Zhiguo patted his thigh: "Duan Lanzhi left his hometown in Sichuan Province on May 26 and arrived in Liancheng on June 15. During this period, Duan Lanzhi and Luan Dongtian have been traveling together in Tibet Province."

"Between June 15th and June 20th, it has been three months since Duan Lanzhi was killed. It must be impossible for her family to contact her, but her family did not call the police. Why?"

"Also, according to common sense, no one should know about the time Duan Lanzhi and Luan Dongtian went to Tibet."

"If Luan Dongtian really wanted to kill Duan Lanzhi, he could do it during this time and bury her body on the plateau. I believe no one will be able to find her."

"Could it be that Luan Dongtian really wasn't the murderer?"

Wu Zhiguo's words explained Chen Yan's doubts.

"Captain Chen, what should we do next?"

How to do?

Chen Yan shook his head: "There is no good solution now, there are only two things that can be done now."

"One is to conduct a detailed investigation of Duan Lanzhi's husband. If he finds out about Duan Lanzhi's affair, then he has a motive for committing the crime. We only checked the record that her husband did not take public transportation to Liancheng in the early stage, but we don't know about him. Like Duan Lanzhi, did you come to Liancheng by private car or other means, and inform Sichuan Province to check the whereabouts of Duan Lanzhi's husband after May 26."

"Secondly, wait for the results of the identification of traces in the room where Duan Lanzhi lived. Based on the current clues, the place where Duan Lanzhi was killed should be Room 1103 where she lived. If there are traces left by other people in the room, then this other person It is very likely to be the murderer, if there are only traces of Duan Lanzhi and Luan Dongtian in the room, then there is a high probability that Luan Dongtian is the murderer!"

The wait was not long.

Three hours later, the investigation report of Room 1103 was placed on Chen Yan's desk.

As for the result, everyone in the serious crime team was a little surprised.

The leader of the technical team responsible for identifying traces reported.

"We found traces left by four people at the scene, most of which belonged to Duan Lanzhi and Luan Dongtian, but there are two other test materials that are hair of different lengths. We have obtained DNA information, one is A man's, and a woman's."
