"Wait," Zhang stopped him and asked, "Do you have the key to the iron gate?" ”

"Yes, I'll go get it."

After the staff left, Xiao Wu and Xiao Zhang only stared inside the iron gate, they both wanted to know what Xie Yunmeng was doing as soon as possible?

Knowing that it was the criminal police who were handling the case, the attitude of the staff became very enthusiastic, she quickly took the key, opened the door, handed the key to Xiao Wu, and then watched the two people walk in, with a curious look in her eyes, after all, it is the first time for many people to watch the criminal police handle the case.

Xiao Wu and Xiao Zhang closed the door behind them, not letting the staff come in and disturb them, and then strode towards the part of the wall that Xie Yunmeng kicked open, and looked inside, Xie Yunmeng was squatting under a tree, and there seemed to be a person lying on the ground.

"Officer Xie, is it Shen Muyan?"

The two of them ran closer, and Xie Yunmeng said, "It seems that he is dead, he was poisoned, you see this." After speaking, Xie Yunmeng said to the open mouth of the corpse on the ground: "The mouth and tongue, as well as the entire mouth and throat are bruised, and the tongue is swollen, which seems to have been forcibly poisoned." ”

"Forced poisoning?" Xiao Wu was a little incredulous, and said: "Ordinary police officers should have some combat effectiveness, is it so easy to be forcibly poisoned?" ”

Xie Yunmeng said: "It's not easy, you see that Shen Muyan's clothes are torn in many places, they are all mud, and there are abrasions on his hands, forearms and shoulders, and it is obvious that he has fought with someone." ”

"Then how do you know that Shen Muyan's body is here?" Xiao Zhang asked the question they were most concerned about.

"It's a garbage truck, and the car was deliberately placed there in reverse, maybe to cover up something, but I found that a wooden board on the side of the garbage truck was broken, and the motor on it also had traces of being hit, and the halter and the wooden handle on the side were damaged, and when I pulled up the wooden handle, the halter was obviously tilted to the side, not the normal kind of skew."

"My guess is that someone was wrestling near the garbage truck, which caused the halter to be broken and the planks to be shattered. But the people who are fighting can't be in the alley, otherwise they will be discovered by the staff outside. ”

"I also found the marks on the tires of the garbage truck on the ground, which led to the outside of the wall, but there was not even a small door on the wall, and the only possibility was that someone had torn down the wall, put the garbage truck outside, and then built the wall."

Xiao Zhang asked, "Is it so troublesome?" If the garbage truck is in the yard, just go around from the outside and put it in the alley? ”

A few minutes later, Aunt Lu got down from the stool with a puzzled look on her face and said, "Huh? It was really strange, the old lady sat exactly the same as yesterday, and she didn't even change the position of the hand shaking the fan. ”

"Are you sure?"

"I'm pretty sure that the things in the yard don't seem to have touched since yesterday."

This time, Xie Yunmeng began to get nervous, and he said to Aunt Lu: "You go back now, I want to go to the courtyard to have a look." Later, if the old lady is okay, you can help me prove it if you ask, I went in because I was worried about what happened to her. If you don't hear anything, then you assume that it doesn't exist and don't ask why. ”

"But how do you get in, Mr. Officer?" Aunt Lu asked.

Xie Yunmeng said: "You don't have to worry about this, don't look behind you now, go back quickly, and take care of all the staff of the shelter, no one is allowed to come into the alley." ”

"Okay."

Aunt Lu walked back with some hesitation, Xie Yunmeng used her body to block the gap in the wall behind her, so as not to let the corpse frighten her, and after the people disappeared, Xie Yunmeng climbed onto the wall again, this time without pausing, and jumped directly into the yard.

——

What's really going on in the yard? Let's talk about it later, in addition to Xie Yunmeng's actions, there are two other places that must be explained first.

One of them is Yan Muheng's actions after arriving at the airport, and the other is what Yun Yeyao's stepmother did after separating from Huang Wei?

Let's talk about Mrs. Yun first, Huang Wei left the airport at noon with her, it takes more than half an hour for the car to drive back to the villa, and it won't take more than ten minutes for the two of them to talk at most, that is to say, before Yun Yeyao learned that Mo Haiyou arrived at the airport, her phone should have been called to her son a long time ago, but what is the reason why Yun Yeyao has not received a call?

In fact, it is very simple, Mrs. Yun came home and met Yun Yeyao's father: Yun Yi City.

Mrs. Yun has never lied to her husband very much, under the questioning of Yun Yicheng, Mrs. Yun said that Yun Yeyao and Xie Yunmeng came back, Yun Yicheng actually missed his son, after thinking about it again, he decided to go to the airport together to see what happened? If necessary, you can use his connections here to help Yun Yeyao.

"I'm not saying that it will have to be related, I'm just guessing whether the 'Yun' on this note is the murderer who wants to draw our attention to Mr. Yun and his son, maybe the criminals who were caught by Yun Yeyao before want to take revenge, or for some other reason, they left this word."

"What other reason do you say?" The police officer put down the paperweight in his hand, his eyes flashed with doubt, he didn't understand what Xiao Xie meant by 'what else reason'?

Xiao Xie continued to say to himself: "I'm also guessing, because it's too much of a coincidence, this villa is seven, I just heard that the villas where Yunyi City lives are also seven, and only two villas in the gardened villa area are duplicate number plates, which are precisely the murder scene and Yunyi City's home." ”

"That's true, but this coincidence doesn't tell the story."

But why did the murderer leave a note? And just writing one word, isn't it just to highlight the meaning of the word 'Yun'? Xiao Xie said: "Criminals do not blame unrelated people for their crimes for no reason, and the probability of this happening is almost non-existent." ”

The police officer pondered Xiao Xie's words, and he said, "Could it really be that the criminal once suffered the loss of Yun Yeyao and now wants to take revenge?" But I still think it's very unreliable, I heard that most of the people Yun Yeyao participated in were vicious homicides, and the criminals caught in that kind of case really had a chance to kill people a second time? ”

"Maybe it's not the criminal himself, but his relatives?"

"I still can't believe it, I think the word 'yun' is just a way for criminals to confuse our vision, and it has no practical meaning at all."

The two of them stood at the long table to discuss this issue, and the police officers could not fully agree with what Xiao Xie said, but from another point of view, these words were also remembered by all the investigators present.

"That's right!" Yun Yeyao immediately let out a sound of praise like admiration, and said to Mo Haiyou: "Xiao Zuo, Xiao Heng is really suitable for being your assistant." ”

"Don't talk nonsense, concentrate on solving the case." Mo Haiyou's face changed in a second, and he scolded Yun Yeyao in a low voice.

Yan Muheng said to Yun Yeyao: "Xiao Yao, just now you said that you are not sure whether the person who helped the murderer clean up the scene is a shield or a betrayer, but you actually want me to think about the answer, right?" To the murderer, he is neither a shield nor a betrayer, but a person who wants to protect himself. ”

"Well, and this person has been caught by us, and now Officer Fu Yan is interrogating them, but...... Officer Fu doesn't seem to approve of my reasoning, which can only be proved by Xiao Zuo, because there are still many doubts at the scene, which are not as simple as they seem on the surface. ”

Mo Haiyou said: "Wait a while, I'll go and see the suspect you caught, and listen to how Officer Fu judges, the clues on the body can play a certain role in proving it." Further investigation of other evidence is required. ”

The conversation between the three of them ended here, and the police officers who came over had been waiting for a while, and Yun Yeyao only heard that Xie Yunmeng had discovered the third homicide at this time, and he thought that he was not worried that Xie Yunmeng would stay there alone, and immediately went to the alley between Changqing Road and Baita Road.

At the same time, Fu Jun, who was guarding the police station, also received a call from his younger brother and learned that Shen Muyan had died, and Fu Jun immediately reported to his superiors at the police station where he was located, requesting to participate in the investigation of the homicide case with his younger brother.

——

Inside a house near a garden view villa area

The handsome man asked the dark shadow sitting across the table, "I said, do you really think that's okay?" ”

"Almost, there's no other way, that kid will definitely come out." A deep voice replied.

"But I always feel very dangerous, those three people have solved a lot of cases, and we will soon be seen through." The man's tone was full of fear, he was thinking about the person he had known before, and the impression of this person in his mind was very different from the past. That's why he's afraid.

The black shadow comforted him again: "You don't have to worry, even if they see through something, it's all done by that kid, I and Xiaoice have made it together, the incident at the airport is enough to take the investigation steps of the crooked criminal police, not to mention that he can't let go of Xiaoice at all." ”

As for Fu Jun, with his colleagues from the police station, he was rushing to the scene where Xie Yunmeng was to help.

Prior to this, Fu Yan had already informed his brother in detail of the information that Xiao Wu and Xiao Zhang had fed back, so Fu Jun could easily find the correct direction.

Yun Yeyao's analysis of the scene environment continued, the time had passed three o'clock in the afternoon, the sun in the yard was very dazzling, but the temperature was not very high.

Yun Yeyao said: "Xiao Meng, the old woman's body is not decomposed, and the yard does not smell the smell, although the sun is dazzling now, the temperature will not be as high as in July and August, and we are near the sea here, and it is much more comfortable in summer than in the south, and it often rains and blows. ”

Xie Yunmeng retorted: "Look at her appearance, her skin is dry, red and black, showing large traces of sunburn, her expression is painful, and there are no other wounds on her body, she is not killed by exposure to the sun, then she can only die of sudden illness, I have also checked his mouth, and he has not been forcibly injected with poison." He couldn't tell the specifics, and he could only wait for the forensic doctor to arrive.

"I think it's more likely to die of a sudden illness, after all, the old woman is over 80 years old, and she is tied to a chair and doesn't move, so it's easy to get sick. And she shouldn't have died yesterday either, I think the old woman who the staff saw yesterday was still alive, and it took a night of inactivity to cause her death. ”

"No, Haruka." Xie Yunmeng retorted: "If the old woman didn't die yesterday, then how could her skin state show this way? The skin of a living person will be red and hot when sunburned, and after a long time, there will be edema and large peeling, but the skin on this old woman's body seems to be scorched, black, shriveled, and dry, which is the result of a long period of direct sunlight after death. ”

"But it's not winter, why hasn't she rotted, the air outside the city is humid, and in many ways, she can't go a day and a night without rotting." Yun Ye approached the corpse, but still didn't smell the stench, but smelled a faint scent of grass.

"What is this?" Yun Yeyao asked suddenly.

Xie Yunmeng didn't understand what he meant, and asked rhetorically, "What did you say?" ”

"I mean the smell of grass, haven't you smelled it just now? Right on the corpse. ”

"This may have been left on the body by the old woman when she planted it."

"But she grows vegetables, but what she leaves on her body is the smell of vanilla, which is too strange, Xiao Meng."

Wang Minglang and Wang Haicheng were soon taken to a small room temporarily provided at the airport, where Fu Yan sat alone and waited for them.

When he saw people coming in, he motioned for the police to stand guard outside the door, and he pointed to the two chairs in front of him and said, "Sit down." ”

Wang Haicheng nodded and sat down first, while Wang Minglang kept looking out of the door, as if waiting for Wang Lili to appear.

"Wang Lili and you are interrogated separately, you don't have to wait." Fu Yan reminded him.

Wang Minglang blurted out all of a sudden; "Why?" When the words came out, he realized that he shouldn't have asked, his face was blue and white for a while, and his eyes didn't know where to look.

Fu Yan didn't bother with him, and said again: "Sit down." ”

When Wang Minglang sat down, Fu Yan cleared his throat and said, "Now every question I raise, you must answer truthfully, and it is also good for you to cooperate with the work of the police, understand?" ”

Wang Minglang didn't react, but Wang Haicheng nodded heavily, so Fu Yan's eyes focused on Wang Minglang, and he was going to start with this café waiter first.

"Wang Minglang, it is an indisputable fact that you and Wang Lili attempted to attack witnesses and take away the corpse, you have no way to deny this, and Wang Lili has no fear at all when she sees the corpse, which shows two points, either she is naturally bold, or she has already seen the corpse, and there are more fearful things in her heart that control her."

"I don't believe that anyone will be as calm as usual when they see a corpse for the first time, at least there should be surprise, so I choose the second answer, Wang Lili has already seen the corpse, and she knows the identity of the deceased, and she also knows who killed the deceased. Her attempt to take away the body was to shield the murderer. ”

"So who is the murderer that Wang Lili wants to shield? Wang Minglang, the most likely is you. Who is the person covering Wang Lili's car? It's you, who is the person pretending to be a waiter trying to deceive Mr. Yun's mother and son? It's you, and someone at the airport saw you hiding in the corner looking through a black phone, which was confirmed to be Mr. Yun who told you to go to the café to get it. ”

Later, these two people will definitely contact him by phone, Mo Haiyou thought, and began to carefully inspect Shen Muyan's body. It is obvious that the scene has been touched and that the mound has been freshly opened.

"Did you dig up Shen Muyan's body?" Mo Haiyou asked the officer.

"No, it was dug up by Officer Xie, but he didn't move the body, and Shen Muyan was lying like this."

"Okay, I got it."

Let the police guard the gap in the courtyard wall, Mo Haiyou lowered his head and sniffed Shen Muyan's blackened mouth, there was a faint smell of nicotine, nicotine is commonly known as nicotine, easy to get, and the volatility is also very good, to say that the murderer used a sufficient amount of nicotine to kill people, if the time is long enough, it is possible that Mo Haiyou can't smell it now.

But the condition in Shen Muyan's mouth did not look like nicotinic poisoning, his lips were swollen, and the entire mouth and around his lips were already black and purple, including the mucous membranes and skin in his throat.

Nicotinoid (nicotine) generally acts on the nervous system of the human body, as well as the heart and respiratory system, although there will be a burning sensation in the mouth and irritating the throat, but it is not as serious as Shen Muyan's condition.

And acute nicotinic poisoning can cause people's nerves to be overexcited, unable to control vomiting, diarrhea, sweating, etc., Mo Haiyou carefully inspected Shen Muyan's whole body, there was no salivation at the side of his mouth, there was no foul smell in his mouth, and his body was covered with mud, but there was no sign of sweating in the clean place between his neck and fingers.

After checking the lower half of his body again, there was no diarrhea, and Shen Muyan's expression made people feel that he was in great pain before he died, and it should have been poisoning that caused severe pain, but Shen Muyan did not press his abdomen with both hands, indicating that it was not abdominal pain, and one of the most obvious characteristics of nicotinic poisoning was abdominal pain.

Therefore, Mo Haiyou immediately ruled out the possibility of nicotine poisoning, and there was a smell of smoke in his mouth, which may be caused by Shen Muyan's usual fondness for smoking.

The obvious signs of carcass poisoning, but the absence of vomiting and abdominal pain, also ruled out the possibility of arsenic trioxide (arsenic) poisoning, and there was no mucosal ulceration and bleeding in the throat of the corpse, which was also a factor in ruling out arsenic powder poisoning.

So what should be the toxin? Mo Haiyou opened the corpse's mouth with pliers, and found that it was already very stiff, and the corpse's neck was as hard as wood, and there was a phenomenon of nerve spasm, and the shoulders were also shrunk, and then looking at the shape of the corpse's body, it had curled up into an arch.

In this way, the likelihood of phytotoxin poisoning is greatly increased, with the strychnine poisoning state being the most close. Nux cinchnine can be extracted from many plants, and the poisoning reaction is not fast, but it is very scary, and the skin irritation of the victim is also very strong.

This is the second time he has seen Mo Haiyou, the first time is from the photo, is that serious person really his lost bloodline? Before seeing me, Yun Yicheng's heart was very firm, but today he secretly glanced at the forensic doctor, and he instantly felt the heart-rending pain in the past.

Is he really? That man had already died in the trap of the Yellow Butterfly Flower, would he really come back? ’

Yun Yicheng closed his eyes, it was like a joke that God had played on him, an extremely cruel joke.

Trying to adjust his mind, Yun Yicheng looked out of the courtyard again, his eyesight was as good as his son's, and he had never faded because of age, and the clouds in the sky gradually became thicker, like Yun Yicheng's inner turmoil.

A moment later, two people appeared in his field of vision, it was Yun Yeyao and Xie Yunmeng, they didn't seem to have any intention of returning home, but hurriedly walked forward.

Just when Yun Yicheng was puzzled, they stopped again, and they didn't know what they said, Xie Yunmeng scratched Yun Yeyao's nose very affectionately, and Yun Yicheng's anger also came up because of this, and he was originally unsettled.

Striding out of the courtyard, Yun Yicheng stood where Yun Yeyao could see and glared at him, which made Yun Yeyao, who was still immersed in happiness just now, gasp.

But Mr. Actor still mustered up the courage to walk in front of his father, and of course the criminal police followed him all the time.

"Daddy."

"Don't call me Dad, do you still know to come back?"

"I'm sorry, uncle, we can ...... well"

Xie Yunmeng wanted to say, "Can you talk about it?" But it was interrupted by Yunyi City in an instant.

"Shut up, Xiao Yao, go back with me."

After speaking, Yun Yicheng picked up Yun Yeyao and walked home, ignoring Xie Yunmeng at all, the criminal police chased after a few steps and stopped the old screenwriter and said: "Uncle, we are not only here to see you now, but also to investigate the murder scene, so please let Xiao Yao be with me." ”

"Homicide scene?!" Yun Yicheng didn't give Xie Yunmeng any face, and shouted: "You are a criminal policeman, it is your responsibility to investigate the scene, what does it have to do with my son?" Now please get away from our house immediately! ”

"Dad, don't have this attitude towards Xiaomeng, he has saved me many times, and I am willing to be with him, I have to invade his life! Xiao Meng is not wrong! ”

Yun Yeyao broke free from his father's hand and yelled at him, and the guards on duty at the gate looked at them, thinking that they would fight at any moment.

Xie Yunmeng said: "Then writing the word 'Yun' means that he wants to blame you or your uncle, so it can prove that it has nothing to do with your family, right?" ”

"Yes, our family and this villa are the same as 7, and the previous incident proves that the suspect does have the intention of marrying the blame, the note can only explain one point, maybe the culprit is not the murderer, but his clumsy tricks are easy to be discovered by the police at all."

"That's true, and the note doesn't have to be used as evidence. It's just that I wonder why this note wasn't found by the police who just investigated the scene. Xie Yunmeng said as he took the note back and put it back in its place.

Yun Yeyao kept staring at his hand where he put the note, and suddenly asked, "Xiao Meng, it's too strange." ”

“！” Xie Yunmeng couldn't help but look down at Yun Yeyao's face, at this moment, this delicate face had a serious face, Mr. Criminal Police didn't understand what Yun Yeyao had found again, and looked at him with a frown.

Yun Yeyao said: "I think there are indeed people who want to hook up with our family, but his behavior is too strange, first of all, Shen Muyan, actually died in Wang Haicheng's house, the suspect asked Shen Muyan to tell me that something happened at home, at most it played a role in diverting attention, but at that time, the police had already discovered the homicide case of Gu Wu's family, what was the use of him diverting his attention?" ”

"And the police will definitely find out that I am not a relative of the deceased, and they will not come to disturb me, does he want me to take the initiative to appear in front of the police? What's the point? I couldn't understand what the outcome of this suspect wanted, but I became more and more convinced that this suspect could not be the murderer, he just wanted to cover up something. ”
