[Former residence of mountains and rivers, half past eleven in the evening]

According to the timeline description of several people, Ling Yu Chuming and Shu Xiaoran first locked the suspects on Dong Jiali, Lin Xiao and Steward Zhang, and then according to the newspapers and conversation records found in Dong Jiali's room provided by Yang Zixuan, Dong Jiali was inevitably more suspicious.

If the deceased was really killed between 9:40 and 9:45 p.m., a five-minute time, then Dong Jiali was in line with the time, and she also had a certain motive to kill.

thought that Dong Jiali would confess in front of these evidence, but her confession was that she did not kill Lin Zipei, although she did want to kill him to avenge her husband, but at the same time she also said that because her room was turned over by Yang Zixuan, she dispelled the idea of killing Lin Zipei to take revenge.

Moreover, she also emphasized that when she asked Lin Zipei about the previous conversation between him and Lin Ziyuan, Lin Zipei flatly denied it, and he did not admit that it was a conversation between himself and his brother. He believed that someone had deliberately used his mobile phone to have this conversation with his brother, forcing his brother to death.

Maybe this is one of the reasons why Lin Zipei dodged Dong Jiali's eyes. Although it wasn't he who killed his brother, Lin Ziyuan jumped off the building because of himself. But now that Lin Zipei is also dead, what was the matter like back then, if it was really not Lin Zipei and Lin Ziyuan talking, then there is only one person who knows the truth, and that is the person who used Lin Zipei to send a message to Lin Ziyuan to pretend to be Lin Zipei and kill Lin Ziyuan!

The current clues can only be said to suspect that Dong Jiali is suspected of committing a crime, but it is not yet certain, in response to what several people said, they decided to go to the bedroom on the third floor to check the scene.

When they came to Lin Zipei's bedroom on the third floor, the blood flowing out of the back of his head had already coagulated, and the blood clots lying on the sheets had made the sheets cold, and when they entered the room, there was still a smell of smoke, but compared to when they first came in, a lot of the smell had dispersed. Ling Yu entered the room and looked at the situation inside the room.

The first time you come in, you may only focus on the deceased and ignore your surroundings.

She put aside the corpse and disappeared, looking at the situation under the bed, the cigarette butts all over the ground, it looked like there were seven or eight cigarettes at a glance, and there was a lighter next to it, Lin Zipei What's the matter, how could she suddenly smoke so many cigarettes, and the strangest thing is that some of these cigarettes are not finished, and some are generally thrown away after only smoking, is this venting?

Dong Jiali had said when she stated the timeline before that when she went to the toilet and passed by the bedroom of the two on the third floor at nine o'clock, she heard the sound of a quarrel, thinking like this, it may be because the two quarreled Lin Zipei was in a bad mood and wanted to smoke, but found that there was no lighter, although Yao Jingwen quarreled, but seeing that Lin Zipei wanted to smoke but didn't have a lighter, she still couldn't bear to go to the grocery room and get a lighter for Lin Zipei.

This is just a hypothesis.

When Ling Yu was looking at the scene, Shu Xiaoran seemed to be spraying some liquid towards all corners of the room, because it was mentioned before that there was a little bulge in the concave part of the back of the deceased's head, so she suspected that Lin Zipei might have hit something in the room before, and what she was holding in her hand was the luminol liquid that she used when dealing with the Kangduo case, and used it to test the bloodstain reaction in the room.

On Chu Ming's side, he wandered around the corpse, trying to find some other clues.

The smell of blood permeated the corpse, and although the blood had coagulated, the nauseous smell that had come to the nose had not diminished at all. The room could almost be described as the smell of blood mixed with smoke and danced together around the terrified corpses.

Chu Ming put on a mask and put his head closer to the sheet, for fear of missing some important clues. He lifted the glasses on the bridge of his nose, and while observing the corpse's surroundings, he accidentally touched the chandelier next to the corpse with his elbow.

Chandeliers are getting bigger, but they're heavy. At this moment, when Chu Ming was looking intently at the chandelier that he had accidentally touched, a subtle object was caught by his gaze hidden under the height of the lenses.

He hurried forward, and beside the chandelier were tiny, barely visible ashes. Chu Ming carefully put it away with tweezers, held it in front of his eyes, and looked at the small ash. He placed it in front of his nostrils and sniffed the ash slightly.

However, he knew that this was not his strong point, and he didn't understand anything after smelling it for a long time. This kind of thing should still be found in Ling Yu.

"Boss, come over here." Chu Ming said to Ling Yu, who was not far from him.

"What's wrong?" Ling Yu rushed to hear the sound

"You smell what was left over from the burning of something."

Ling Yu pressed the tip of her nose forward, and she closed her eyes to smell the ashes.

"The smell is too light to smell, but it smells like cigarettes." Ling Yu opened his eyes and said to Chu Ming. Maybe it was left by Lin Zipei when he smoked before.

On the other hand, Xiao Ran seems to have made a new discovery:

"Sister Ling Yu, come and see this!" Xiao Ran stood in front of the windowsill and said to Ling Yu.

Ling Yu left Chu Ming's side and went to Xiao Ran's place. Chu Ming also followed. Xiao Ran asked Chu Ming to turn off the lights and come over.

Then, the three of them looked at the position of the windowsill together, and a faint blue light faintly appeared on the windowsill. If there is none, although the amount is not very large, it is enough to prove that there are blood stains here. After that, Chu Ming turned on the light.

Except for Ling Yu, Shu Xiaoran, and Chu Ming, everyone else was waiting outside the door of the room, probably thinking that the smell inside the room was too disgusting. The most nervous should be Dong Jiali, she is the most suspicious one at present.

However, the three people in the house never found Qin Jian's location. And at this moment, footsteps came from the top of the stairs, and everyone looked in the direction of the stairs, not knowing where Qin Jian had just gone, but Qin Jian ignored their gazes, and he seemed to be holding something in his hand, and went directly to the scene of the crime.

"Ling Yu, I'm back!" Qin Jian closed the door after entering the room.

"Where have you been?" Ling Yu asked Qin Jian, and at the same time cast a contemptuous look, as if to say, this guy is always so unreassuring.

I saw Qin Jian put out the object he had just held in his hand and presented it in front of the three of them, and then said:

"I just went to the grocery store!"

They saw that what was in Qin Jian's hand was a bundle of fishing line.

"What are you doing in the grocery store?" Chu Ming couldn't help but ask.

"I don't know, my gut feels like there's something in there." Qin Jian replied.

"Is this the clue you found?" Shu Xiaoran picked up the fishing line in Qin Jian's hand.

"Hmm." Qin Jian nodded, and then continued: "When you were sorting out the timeline, I heard that three people went to the grocery room tonight, and I thought that they might find something inside, so I went to the grocery room, and sure enough, I found that the grocery room was turned over, and the most messy place was the place where the wine glasses were placed, and in addition to that, there was the shelf where the lighter was placed." ”

"Then why did you bring the line?" Chu Ming asked.

"That's the weirdest part, the glasses and the lighter are obviously overturned, but the line looks neat, but it's not neat, and it feels like you don't want people to know that it's been overturned."

"Do you suspect someone is using fishing lines to commit crimes?" Shu Xiaoran asked.

"Well, I said, it's just a gut feeling on my part."

"Wait a minute, lend me the line!" Ling Yu took the fishing line directly from Shu Xiaoran's hand, and then found the lighter on the ground, she exposed a small head of the fishing line, and then lit it with a lighter, under the light of the lighter, the thread in front of the fishing line was burned a little bit, and the ashes that had been burned by the fire fell on the blood-stained sheets.

Ling Yu used tweezers to pick up the newly formed ashes, and then stepped forward to smell it. Then looking back at Qin Jian, a cautious smile came.

"Humph!"

Qin Jian couldn't help but shudder when he looked at Ling Yu's appearance, as if he was really frightened.

"Qin Jian, I have to say, your intuition is really accurate."

"Huh?" Qin Jian looked at Ling Yu, in fact, he should have understood what things were like.

According to the new discoveries at the scene, Ling Yu and others finally summarized the following points after a calm analysis:

First of all, Xiao Ran found a bloodstain reaction at the location of the windowsill, and only Lin Zipei and Yao Jingwen lived in this room, so the bloodstain was either Lin Zipei or Yao Jingwen's, and it must have been stained with this bloodstain before Lin Zipei was hit by the chandelier, and the position of the bed was a certain distance from the windowsill, so it could not have been splashed when it was hit.

Then there is the fish coil that Qin Jian found in the grocery room, Ling Yu had already experimented just now, and the taste formed after the burning of the fishing line was the same as the taste of the ashes that Chu Ming found before, but the ashes that Chu Ming found had some smoke smell on them, originally thought that this was because Lin Zipei had smoked a lot of cigarettes before, and there was too much smoke in the room. But suddenly they remembered the cigarette butts on the ground again.

Some have only half smoked, some have not finished smoking, but they are all thrown on the ground, and these cigarette butts have a characteristic. That is, the burning place has not been trampled on, and there is no sign of being pressed down to extinguish the fire.

The strange cigarette butts and the fishing line that Qin Jian found, they suddenly had a brain hole, Lin Zipei may have really killed the reason for hitting the position of the windowsill, and then the murderer used the fishing line and cigarette butts to cooperate together to make a time-delay device.

The killer first dismantled the chandelier manually, then hung it on the ceiling with a fishing line, then tied the cigarette butt to the fishing line connected to the ceiling, lit the cigarette and let it burn, and when the cigarette burned to the fishing line, the fishing line would be burned. The chandelier will come down.

As long as the position of the deceased is placed accurately, it will give the impression that the chandelier has fallen down and hit the deceased. It's just that the cigarette butt that fell on the bed hasn't been found yet.

"In this case, Lin Zipei's time of death was not between 9:40 and 9:45, let alone being hit by a chandelier at 9:45?" Shu Xiaoran said to herself.

Ling Yu stood up and looked at Lin Zipei's corpse and the chandelier next to the corpse with sharp eyes:

"That's right, Dong Jiali said before that she heard someone arguing in the room at nine o'clock, and if she was right, then the real time of death would be between nine and ten and nine forty! That's what you say! The murderer could only be her! ”

Ling Yu's eyes seemed to pass through the closed door, looking at someone on the other side of the door!
