Everyone focused their eyes on the stone on the table, and Lin Zidong said again without hurrying

"Let's imagine, if the murderer is three people, it is easy to explain, after they strangled Xu Li to death with a rope, the murderer A who pretended to be Xu Li first walked into the toilet, but you should have seen it when you investigated the scene, there is an eight-storey residential building about 20 meters away from the toilet, which is another key point in the case."

The big cat and the others on the side still listened in a fog, "Then there is no way to explain how the murderer brought the victim's body into the toilet unconsciously."

Seeing that everyone was still confused, Lin Zidong had no choice but to explain patiently

"If the murderer B is on the roof of the building opposite, tie the hemp rope that he has prepared in advance to this stone and throw it into the latrine. Murderer A took the rope that was thrown into the toilet and fixed it, so that Murderer B, who was on the roof of the opposite building, could tie the hair on the corpse to a pulley on the hemp rope, and then use the pulley to send the corpse into the toilet through the toilet window, so that there would be no damage or flaws on the corpse's body. Murderer A took the corpse and by virtue of the height of the hemp rope, she could easily create the illusion of hanging herself, and then she used the other hemp rope provided by Murderer C, who was standing opposite the downstairs at this time, to leave with a pulley."

At this time, Baozi, who had been silent, raised questions

"Since Murderer A left the toilet through a pulley on the hemp rope, how did the hemp rope tied to the toilet take it away?"

Lin Zidong knew that they would ask that

"If my inference is correct, there is only one explanation, that is, Wen Ting is also one of the three murderers, after she arrived at the company in the morning, she hurriedly walked into the toilet, hid or threw away the hemp rope that was still in the toilet at this time, and then ran out of the toilet pretending to be very panicked, and then called the police"

"Head, these are your inferences, we don't have substantial evidence, and why did Wen Ting die later?" The big cat looked up and said

Lin Zidong slapped the big cat's head and said angrily

"Do you need to tell me? I just want to tell you that this case is not just a suicide conclusion, and we can't let go of any possibility! ”

Everyone nodded and responded, "Head, we know"

However, Lin Zidong didn't know that the reasoning he had just made was the truth of the whole case.

"Now assign the task, big cat and black dog, you go to investigate what contacts and interactions the three deceased had before their deaths, the more detailed the better." After Lin Zidong finished speaking, he turned his head to Baozi and the others

"Bun savage, you two go and find Xu Li's boyfriend before his death, and then take him back to the police station for questioning. The rest of me went to the roof across the street from the crime scene to see if there were any clues."

After watching everyone nod and leave one after another, Lin Zidong said to Zhang Yao with a smile, "Mr. Zhang, if you think there is nothing to do, you can also go to the roof with us."

Of course Zhang Yao knew what he was thinking, he was afraid that the female ghost would appear again, "Anyway, I'm idle and fine, I'll go and see with you."

For two days in a row, Zhang Yao accompanied Lin Zidong and others to look for clues, but he was also happy to do it and felt the feeling of investigating the case.

On the way, I learned from Baozi Savage that Xu Li's boyfriend suddenly disappeared.

This made Lin Zidong even more suspicious that there might be him in the murderer's hands

It was not until the morning of the third day that the case took a major turn.

"Head, we found a big discovery, Xu Li's boyfriend is named Luo Chongliang, it turns out that he is the ex-boyfriend of the second deceased Gu Hong, they have been together a long time ago, and the third deceased Wen Ting and Gu Hong have been playmates since childhood, and the relationship is very good" The big cat walked into the office and hurriedly said to Lin Zidong.

Lin Zidong fell into deep thought after hearing this: "Is there anything else?" ”

The big cat continued

"Well, there is also this Luo Chongliang who is very handsome and speaks humorously, so he is a girl who is allowed, but he is lazy by nature, so he has not had a regular job, and it was because of this that Gu Hong's family forced Gu Hong to break up with him."

At this time, the black dog on the side also interjected, "When Luo Chongliang and Gu Hong broke up, they dated Xu Li, although Xu Li's parents were also opposed, but she was stubborn, and moved out after falling out with her family for the sake of her beloved man." But we found out that in fact, Luo Chongliang and Gu Hong still have a constant relationship behind their backs. Until Xu Li became pregnant with his child, she originally thought that there would be a good turnaround, but ...... It's backfired."

Lin Zidong looked at the appearance of the black dog selling Guanzi, and said impatiently, "If you have a fart, you will let me finish it all at once"

"But Gu Hong is also pregnant with Luo Chongliang's child at the same time, and we heard that Gu Hong's family conditions are much better than Xu Li's family, although it is not rich and expensive, but it is still a little bit of savings, and I know from the mouth of Gu Hong's neighbors that Gu Hong's father once threatened to prepare a dowry of 500,000 yuan when his daughter gets married."

After hearing these words, Lin Zidong's brain worked rapidly, like a computer, and he tried to integrate and connect the information to make it a smooth story.

Suddenly, a flash of inspiration opened his mind.

"Interesting, I think I should know the ins and outs of the whole case," Lin Zidong said with his hand touching his chin

He walked over to the blackboard and wrote out the names of the four men

"The story should be like this, Luo Chongliang used Xu Li as a guise to continue to associate with Gu Hong, but when these two women were pregnant, Gu Hong had a showdown with the family, and in the end the family could only agree, but Gu Hong couldn't accept that Luo Chongliang had other children outside, so she asked Luo Chongliang to beat Xu Li's child"

Lin Zidong sorted out his thoughts and said again

However, Xu Li did not agree to kill the child, which made Luo Chongliang very distressed, and finally he had a murderous intention for the dowry of 500,000 yuan, so Luo Chongliang and the consultant strangled Xu Li to death with gloves and hemp rope on the night of the seventeenth, but because their plan required three people to complete, Gu Hong could only call her best friend Wen Ting for help, and Wen Ting immediately agreed after learning about it.

The black dog seemed to think of something, so he interjected

"But since Wen Ting and Gu Hong have such a good relationship, when Gu Hong died, her reaction to cooperating with the police to make a confession was unusually flat, and she even said that there was no sign of sadness."

At this time, Lin Zidong shook his head with a wry smile, and at some point a blue notebook appeared in his hand, "This is the diary I found in Wen Ting's house, in which I found a secret"

After speaking, Lin Zidong threw the diary on the table......
