Based on this, it is inferred that Wang Haicheng is still very suspicious. The day before the murder, Aunt Lu in the shelter saw an old woman resting on a recliner in the afternoon. According to Aunt Lu's confession, she should have been tied up at that time. Calculate the time. It is the early morning of the second day of the murder, and the time difference between Aunt Lu said was less than two days a little different from what Aunt Lu said.

‘Aunt Lu.’ A sudden inspiration appeared in Mo Hai’s right mind. It seemed that he had heard of this name from other than the stray dog ​​shelter.

Mo Hai temporarily moved his mind that was not related to the corpse and took the scalpel right and cut the skin on the old woman's neck to observe the condition of the subcutaneous tissue and blood vessels. It was not like nicotine poisoning.

He remembered Yun Yeyao and Xie Yunmeng's analysis of the corpse. They believed that the murderer might have applied a mixture of rosemary and nicotine to the skin of the corpse, causing toxicity to penetrate under the skin, and the victim died of chronic poisoning. Moreover, these two things prevent the corpse from rotting.

In Mo Haiyou's opinion, this answer is not reliable. Rosemary and nicotine do have certain antioxidant effects, which will prevent the body from rotting, but the effect will never be obvious.

These two are things with a strong smell. Sometimes they are dyed on the body or clothes and will not dissipate for a long time. Especially nicotine, many men who smoke have a tar smell on their bodies all year round.

If the murderer wants to poison the victim by relying on the absorption of his skin, he must apply a thick layer of nicotine on the victim, and he cannot extract so much nicotine from ordinary cigarettes.

Also, the metabolism of the elderly is much slower than that of young people. Even if enough nicotine is applied, it is impossible to poison people to death in a short period of time. The murderer has no need to do that. He just needs to apply nicotine to the mouth of the corpse, and let the poison slowly flow into the stomach with saliva. This is much more convenient.

So how can I explain this when Yun Yeyao smelled rosemary and tar from the body?

First of all, there is rosemary. The old woman's skin is indeed detected, but not much. That kind of thing can be seen everywhere. Although Wang Haicheng's yard is not planted, and his mother is a difficult person to communicate with. But it cannot deny the possibility that she brought rosemary back from other places, such as neighbors or acquaintances.

Then there was the smell of tar. Yun Yeyao and Xie Yunmeng did not look at the old woman's hand carefully. The hand she was shaking had swollen due to long-term exercise. Her fingers were in a strange state. The hand pressed under her body was not much better, and she was congested and deformed.

Mo Haiyou carefully examined the old woman's fingers. The reason for the deformation was not simply excessive exercise or suppression, but because of rheumatoid arthritis, which would cause joints to deform, and the fingers to be skewed and swollen, which was very painful.

In addition, she works all year round and there is a lot of mud in her fingernails, so it is normal for the actors and detectives to ignore it.

In fact, this old woman has a hobby of smoking. Her skin and teeth at the tips of her fingers are yellow and black, and there is a faint tar smell. With this alone, nicotine is not the cause of her death.

He died of neither sudden illness nor nicotine poisoning. So how did Wang Haicheng's mother die? The only reason was to find it from the inside of the body. Mo Haiyou asked the forensic assistant to prepare the desolation tool. He wanted to check the old woman's internal organs and slice it for testing.

Xiao Xie came to Wang Haicheng's house. Following Mo Haiyou's instructions, he and the police began to look for something in the muddy land in the yard. They had to look for both yards. Judging from their careful appearance, the things they were looking for were probably very small, perhaps the pieces of the plant.

While searching, Xiao Xie was still thinking about another thing in his mind, which was related to his disappearance at the beach for no reason last night. While getting rid of the trio's investigation, Xiao Xie also wanted to sort out his thoughts.

Before Mo Haiyou arrived at the scene of the villa murder, the first person who found the body was the housekeeper and then him. When he was checking, Yan Muheng came over. The guy didn't take a look at the scene more, and then he kept talking to Mo Haiyou.

From their conversation, Xiao Xie knew that Yan Muheng had secretly entered the scene alone, before Mo Haiyou arrived. So when did he enter? It could only be before the housekeeper found the body.

This matter is quite strange. No one reported the case. How did Yan Muheng know that there was a corpse here? Maybe he didn't know at all, but entered the murder scene for some purpose. But this was not the point of Xiao Xie's trouble at this moment. He did not doubt whether Yan Muheng was guilty, but was suspicious of another person. Judging from the various signs at the scene, the possibility of another person committing an offense is very high.

And from a certain perspective, this person also has quite sufficient motivation, so Xiao Xie has always been worried. Going to the beach and asking the trio for help is also out of strong concern.

‘How should I find him? This guy is really troublesome!’ Xiao Xie thought, and looked around and no police officer looked at him.

Withdrew his gaze, Xiao Xie continued to think, and the housekeeping aunt's face appeared in his mind, 'Maybe I will get some clues when the work here is finished, find a reason to go there alone.'

Thoughts urged the action, Xiao Xie accelerated his movements and used his hand to push away the loose soil on the ground in the yard.

In a dirty, stinky place, the middle-aged woman sat alone, she was waiting for someone, a demon who came back from hell.

"Knock-knock-knock-knock-knock-knock-"

Although she was mentally prepared, the sudden knock on the door still scared her.

He stood up in fear and walked towards the door. When his fingertips touched the door handle, the door immediately made a squeaking sound, which alarmed the pair of alert eyes in the darkness.

"Don't be excited, be quiet." The middle-aged woman said to her behind her, as if she had countless companions.

When the door opened, a waiting face appeared outside. The middle-aged woman moved the guardrail a little away and let him in.

When she walked to the center of the courtyard, the surroundings immediately started to make noise again. The middle-aged woman had to scold again: "Be quieter! Don't make noise anymore!" Her voice seemed to have magic, suppressing the annoying noise.

"What's the use of you being so cruel? Don't worry about this, talk to me in the house." The visitor was very calm and walked to a small house next to him. There was a table at the door, which seemed to be something like donation box, and it was not clear in the darkness.

The two of them whispered in the room, accompanied by the sounds coming and going in the yard outside, and they couldn't guess what they were going to do?

Soon, the sky turned red in the second half of the night, and it was almost dawn. People came out of the middle-aged woman's place and hurriedly left without any trace.

No one watched him leave, and the middle-aged woman was still sitting in the room and pondering.

——

Lu Jinyan, a housekeeper who was recuperating at home, couldn't worry about the case. It was not her good thing, but the owner of the villa still owed her several months of wages. She wanted to ask who should ask for the wages after she knew it?

After thinking about it, Lu Jinyan decided to ask the detective, so she picked up her cell phone and prepared to call Xiao Xie. At this time, Lu Jinyan realized that she had not recorded Xiao Xie's phone number at all, and there were only phones left by police investigators at home.

She would never dare to ask her to call the police station to ask about her salary. Lu Jinyan dejectedly put down her mobile phone. For a poor housekeeper, the salary for those few months was not a small amount.

‘Oh! It’s so annoying, it would be great if this didn’t happen.’

He picked up the drawing paper next to the bedside table, Lu Jinyan took a look and threw it under the stool. That thing was useless to her.

Moving her body down from the bed, Lu Jinyan moved her hands and feet and walked out of the door. The relatives outside were almost gone. She needed to do some housework by herself. After all, she was not seriously injured and did not need so many people to take care of her.

‘Call them one by one later and tell them not to come, and they are so annoying!’ Lu Jinyan thought, and disappeared outside the door.

The time is after 12 pm on the first day of the murder.

So far, there are many flaws in front of Mo Haiyou. Not only is the autopsy result, but some people are still hiding some things. What is the reason for hiding? The forensic doctor must figure it out.

So he used all the resources he could use. He could not go to the prisoners to ask questions like Fu Yan often. Too much participation in the interrogation would make Fu Yan dissatisfied because he was a forensic doctor and in this case, there was only this role.

Mo Haiyou followed the steps and did not mean to leave the police station mortar room, but half of his heart had reached foreign language. At this moment, more clues were revealed step by step.

Wang Haicheng's mother's internal organ slices have just been tested. Mo Haiyou finally made some substantial breakthroughs in the cause of her death. She said before that she did not die of disease or nicotine poisoning. From the internal organs, he discovered serious internal bleeding, which is very wide, including in the liver, kidney, stomach and intestines, and there are many ruptures of blood vessels.

These are invisible from the body surface. The old woman's painful expression is mostly caused by internal bleeding.

Mo Haiyou opened the abdominal cavity of the corpse, and the blood in it did not turn black, which proved that it was not a judgment that it was poisoned and died, but it also reflected that in addition to a more unacceptable judgment, that is, the old man was immersed in the face of external gravity before his death.

The so-called external gravity hit is not limited to being beaten. If you are beaten, causing internal bleeding and death, there will definitely be bruises on the surface of the body, but there are no other scars or bruises on the surface of the old woman except for the scars caused by the fishing line.

It is not a human beating, but it can only be that the body is squeezed by gravity beyond the range of internal organs, causing internal organs and blood vessels to rupture and bleeding. From this point of view, suicide is also possible, but the premise of suicide is that the elderly can act independently. Judging from the previous judgment of the fishing line, the elderly have been tied up twice, so suicide is not valid.

So where does gravity come from? The only time that is possible is Wang Haicheng, but Mo Haiyou is not going to ask Wang Haicheng again, but he made some unexpected judgments himself.
