Sodium cyanide, a chemical raw material, is a deadly and highly toxic substance as common as arsenic. It is widely used in the chemical industry. A healthy person can die in a short time after taking a small dose.
The "quick effect" feature makes it often appear in suicide or homicide.
"I believed that Wu Zhen committed suicide earlier, and his series of operations on the 21st were completely a person who was about to commit suicide." Fang Yuanhang said, "But which person who committed suicide would pour himself into the cement? Fierce, outrageous! At least he has a helper, and this helper is also suspected of murder."
Due to the serious corruption of the corpse, some surface injuries have been difficult to identify, and the corpse was sealed in cement, and the specific time of death could not be calculated, which brought considerable difficulties to the investigation.
Zhou Yuan insisted that Wu Zhen died in the period from June 21 to June 22, and the vocational school is not a no-man’s land. In order to avoid people’s eyes and ears, the murder should take place at night, and the high probability is on the 22nd in the dead of night. early morning.
"Murdering with sodium cyanide, or Wu Zhen committing suicide, can be done quietly, but the cement mixer will make noise as soon as it starts." Mingshu said, "Either the murderer or the helper, you are not afraid of attracting them. People living in vocational school dormitories?"
After the vocational school was closed, all the faculty and staff should have left, but some logistics staff temporarily lived in the dormitory because they could not find a suitable home. However, within a few months, the remaining faculty and staff have moved out one after another. Some are still in Dongye City, and some have gone to other places. Currently, there are only four people living in the dormitory.
Kong Yuanqiang and Li Gong are a couple with junior high school education. Before the school closed, Kong Yuanqiang was a security guard, and Li Gong worked part-time in a wonton shop on Yilu Street. Because the vocational school provides housing, both husband and wife live on campus.
"We usually never go to the teaching building, it's too far, and there's nothing to see there." Kong Yuanqiang said, "The valuable things in the building have been sold long ago. It's none of my business. We're moving too soon."
"Stealing cement?" Mingshu asked, "Are you sure someone has come to steal cement?"
"Sure." Kong Yuanqiang said, "Did you see the half-dug land next to the teaching building? There was originally a one-story house to be built as an experimental building for the students, but before the construction started, the school would not be able to operate. Now, building materials and cement, don't they all pile up there? There is also a cement mixer. There are many poor people in Yilu Street, and the poor like to pick up a little cheap. Steal it again, go back and use it directly. In short, if the mixer sounds at night, it is guaranteed that someone will steal the cement.”
Mingshu said, "You heard the sound of the cement mixer, but haven't seen it?"
Li Gong interjected: "The main reason is that it's none of our business. I'm still working in Yilu Street, so why bother me?"
The other two logisticians who still live in the dormitory are named Li Meng and Gou Can. They are about the same age as Mr. and Mrs. Kong Li and have similar ideas. They have heard the sound of the cement mixer in the middle of the night, but they have never thought of crossing the entire playground. , to see who came to steal the cement.
Mingshu asked: "On the night of June 21, did you hear the mixer working, or something else?"
Kong Yuanqiang and Li Gong looked at each other, Li Gong said, "It's been more than two months. I don't remember what happened on June 21."
Mingshu had to ask another way, "Then, on a certain night in late June, did you notice something different than usual?"
"I didn't notice the different movements, but hasn't it been hot since late June this year? I have the impression that there will be fewer people who steal building materials and cement later." Gou Can thought for a long time, "Almost no. "
"Yes, yes." Li Gong said, "I didn't sleep well at night. When the cement mixer rang, I was about to wake up. It seems that no one has come to steal anything since late June."
The trace inspector was still busy at the scene. Mingshu looked at the dirty cement mixer and asked, "How long has this thing been used?"
"It's been two or three months." Xiao Man said, "It's gone."
Mingshu walked towards the wall behind the teaching building. There used to be the main entrance of the vocational school, but it was locked after the school was closed. It stands to reason that whether it was a thief or Wu Zhen, it would be difficult for him to enter from the main entrance. But Kong Yuanqiang and others said that there was a breach in the wall, which was made by students to facilitate skipping classes.
"Master, where are you going?" Fang Yuanhang followed, "What did you find?"
"Hot weather can't stop the thieves, only sudden obstacles can stop them." Mingshu stopped by the fence, tore away the grass that was piled up in a mess, and saw the hole that Kong Yuanqiang said was already covered with barbed wire. seal.
"This..." Fang Yuanhang said, "It's sealed like this, no one dares to come in, right? You can't tear off a piece of skin if you force entry."
Mingshu immediately called the trace inspection to investigate.
"Is this what you blocked?" Li Meng asked the other three.
Both Kong Li and Gou Can shook their heads.
"Then it can only be the murderer." Mingshu said to Xiao Man: "Don't let go of all the traces collected here. After late June, Li Gong and others felt that there were fewer thieves, not because the weather was too hot. , but the murderer is unwilling to let them in. Although the location of the cement block is relatively hidden, it may also be discovered by thieves. This barbed wire is the murderer's 'masterpiece'."
"Team Ming, do you join the case?" Yi Fei asked.
The issue of not consolidating the case has been considered by Mingshu for a long time, but there are still many questions that remain unanswered.
At this moment, news came from the entertainment group that Ran He committed suicide.
"Dead?" Fang Yuanhang was surprised, "Is it simply forced to die, or is there another conspiracy?"
The word "conspiracy" stirred Mingshu's nerves. If it is a conspiracy, is Sha Chun's death also a part of the conspiracy
The police car drove directly from the vocational school to the performing arts group.
None of the people who worked there thought that there would be two abnormal deaths around them in a short period of time.
"The news I got now is that Ran He was unable to think about it for a while because he lost his job and his family, and chose to commit suicide." Xiao Yu'an said in the fast-moving car: "Of course, Sha Chun's death caused him a lot of psychological pressure. The group is panicking, and there are many supernatural rumors about the 'Sha Chun's ghost'. Half of the folks in the folk music club have asked for leave."
"Xiao Bureau, I have an idea." Mingshu said, "We have never been able to determine whether Sha Chun was killed or whether he planned his own death. If it is the latter, what is her purpose? She has worked hard for so many years, Can't see any light, finally discouraged, thinking of ending everything with death, and then taking revenge on those who have humiliated her?"
Xiao Yuan had obviously thought of this, "Go on."
"Suicide, and then leave a suicide note, regretting the injustice and indifference that you have encountered over the years. In fact, it can also achieve the purpose of making those people feel guilty." Mingshu said: "But suicide is not as tragic as homicide, nor can it achieve the horror of the rainy night. The effect. The most important thing is that the police will not investigate further after it is clear that it is suicide. The deeper we investigate now, the more filth is exposed by the folk music club, maybe this is what Sha Chun wants to see."
"Then the question goes back to what we discussed last time, who helped Sha Chun to commit suicide?" Xiao Yu settled down, "Is this the person who spreads supernatural rumors in the entertainment group now?"
Mingshu pressed his eyebrows, "It's a bit contradictory."
Xiao Yu'an tilted his head, "Huh?"
"I think the Sha Chun case and the Wu Zhen case can be investigated together. The two cases don't seem to have many similarities on the surface, but the inner logic is very deep." Mingshu said, "But Wu Zhen can be said to be dead. Quietly, if it wasn't for the Sha Chun case, we wouldn't have found Wu Zhen at all. The Wu Zhen case is still just an ordinary disappearance case. Wu Zhen's death did not 'revenge' anyone, and Sha Chun The death of Ran He indirectly led to Ran He's suicide, which directly caused the current turmoil in the performing arts group. As far as the results are concerned, the two cases are really far from each other."
"Did Sha Chun know that Ran He cheated on his wife during pregnancy?" Xiao Yuan asked suddenly.
Mingshu shook his head, "It's hard to say."
"Sha Chun may not have expected Ran He to commit suicide." Xiao Yu'an said: "As far as I know, Ran He's derailment, the rest of the folk music club are Ran He's wife Chen Qian and the rest of the Chen family who came to the group. She didn't know until after the trouble. Sha Chun was isolated collectively, and she had no way to know about it."
Mingshu said, "Did Ran He commit suicide out of Sha Chun's expectation?"
Xiao Yu'an took a deep breath and could see that he was also confused, "Then it depends on the sacredness of the person who helped Sha Chun to commit suicide."
No substantive results were discussed, and the police car has arrived at the entertainment group.
Ran He was lying on the Pingba under the new building, surrounded by thick blood that had spread.
Mingshu saw Chen Qian, and when his eyes met, Mingshu noticed a trace of strangeness.
Last time at the Criminal Investigation Bureau, Chen Qian tried her best to protect Ran He, so that anyone who looked at her could see that she was a weak wife who loved her husband but was unfortunately betrayed by her husband.
Knowing that her husband cheated, Chen Qian chose not to forgive, and Chen's father used official means to make Ran He lose his job. This is a normal person's reaction. Chen Qian must hate Ran He, maybe she wants to die, but before Ran He betrayed, she loved Ran He, they fell in love when they were students, and now that Ran He is really dead, no matter how much Chen Qian hates it, May not feel sad.
This is also a normal human reaction.
But on Chen Qian's face, Mingshu couldn't see any sadness, only fear and surprise.
Why is Chen Qian afraid? What is she afraid of
There is also an acquaintance at the scene - Ran He's cheating object, Yang Yan.
The horror in Yang Yan's eyes was more obvious than that of Chen Qian, as if it was not her lover who died, but a...
people killed by themselves.
There were many witnesses to Ran He jumping off the building. The facts are clear and there is no possibility of homicide.
But Mingshu was keenly aware that Ran He's suicide was not as simple as it appeared on the surface.
Fang Yuanhang ran over after receiving the call, "Master, what's the matter?"
"Go and find out who is spreading the theory of 'Sha Chun's ghost'." Ming Shu said, "This person may be related to Sha Chun's death."
Noticing that Ming Shu was looking at herself, Chen Qian's expression changed, as if she was trying to hide her fear.
Mingshu told Xiao Yuan about this, and Xiao Yuan narrowed his eyes, "Let the technical investigator investigate Chen Qian's communication records."
The sad truth is buried under the farce of betrayal.
Zhou Yuan found Ming Shu with a set of communication records and bank records, "Team Ming, since three months ago, Chen Qian has contacted Yang Yan many times! She also paid 700,000 yuan to Yang Yan's bank account in batches. !"
Chen Qian and Yang Yan, one is Ran He's wife, the other is Ran He's lover, not a friend or a colleague. How could they have contacted many times during Ran He's derailment and exchanged money
"In addition, Chen Qian contacts a person named 'Wang Xuefeng' every day." Zhou Yuan added: "I checked, this man is Chen Qian's colleague!"
In the face of the evidence, Chen Qian's face was pale and she didn't say a word for a long time.
But Yang Yan couldn't take it anymore and cried, "I never thought that Ran He would be killed! Our plan is not like this... It's all Sha Chun, it's all Sha Chun!"
Mingshu did not expect that a murder case would involve an unrelated ethical tragedy.
In the marriage between Chen Qian and Ran He, it was not Ran He who derailed first, but Chen Qian.
Yang Yan admitted that she took Chen Qian's money, and after she went to seduce Ran He, Chen Qian finally let go, "Yes, everything is arranged by me."
"I have no love for Ran He for a long time." Chen Qian's eyes were blank, as if she had lost her focus, "I chased him back then, regardless of my parents' objection, I would marry him if I lived or died, nothing else, I just thought he was handsome, Talented, people from the countryside, honest."
"But after so many years, I've had enough!" Chen Qian gritted her teeth. "After getting married, the shortsightedness, vulgarity, and ignorance attached to him by poverty were all exposed. His rural home was like a blood-sucking giant. The hole, no matter how I fill it, I can't fill it up. I married a man, why should I support his family? He still wants to bring his poor relatives to the city, how is it possible?"
"I have never had a child with him. His family is always urging him. He has no idea. I didn't have a child because I regret it!" Chen Qian became excited, "If I listened to my parents, how could I live like this? awful?"
After a short pause, Chen Qian laughed dryly, "Last year, after I was with Wang Xuefeng, I realized that people still have to listen to their parents and be with the right people. Ran He and I are not on the same level at all."
Mingshu said, "Last year? You were not pregnant at that time, so you could choose to divorce."
"Divorce?" Chen Qian seemed to have heard a particularly funny joke, "Can I leave? The Ran family has already entangled me, and Ran He and his poor relatives are going to drain my last drop of blood! I cheated, ah, Infidelity in marriage, there is absolutely no reason for the rural people to say, not only will they not agree to divorce, but they will also cause me to ruin my reputation!"
Chen Qian shook her head, "And my parents can't afford to lose this person. I have let them down once by marrying Ran He, and now I can't cause them any more trouble."
"So you decided to stand on the moral high ground and let Ran Cheng be the one who betrayed?" Mingshu said.
"Who told him that he couldn't stand the temptation?" Chen Qian said contemptuously: "I am pregnant—the child is not his, of course, I have to put divorce on the agenda, and he is not satisfied that he can't have a married life with me. I found Yang Yan, that woman is someone who sees money. I gave her a bag and asked her to seduce Ran He, and promised to give her 1 million after everything was done. She agreed, and she was very happy. I thought it was right, Ran He's skin is pretty decent, and Yang Yan doesn't lose out on sleeping. It's a pity..."
Chen Qian lowered her head, and continued after half a minute: "I originally planned to expose this incident in a while, but I didn't expect the Sha Chun incident to happen."
Mingshu said: "In the bureau that day, your 'acting' was good."
Chen Qian's expression suddenly darkened, "I've practiced for a long time, but I didn't expect to show it in front of the criminal police. I didn't think about killing him, I just wanted to divorce him and drive him out of Dongye City, so that he can no longer be Affecting my life. If you want to blame Sha Chun, if it weren't for Sha Chun's death, everyone in the entertainment group would know that Ran He took the lead in bullying Sha Chun, he... he wouldn't want to commit suicide. "
Mingshu sighed, "In your heart, Ran He is quite kind."
Chen Qian was startled, "What do you mean?"
"Do you think Ran He feels guilty about Sha Chun's death, don't you just believe that he still has a little kindness in his heart?" Mingshu said: "You are wrong, his guilt can almost be ignored. He jumped off the building because After losing his family and his job, he jumped out of the countryside and finally found a place to live in the city. He changed the fate of himself and his family - this is the thing he is most proud of. Now it's all ruined, he From having everything to nothing. He couldn't take it, so he committed suicide."
Chen Qian's eyes widened.
"Maybe you thought that Ran He would die." Mingshu stood up, "but you don't care."
"I didn't..." Chen Qian hugged her head tightly, her voice hoarse, "I didn't!"
It has never been an easy task to investigate the source of rumors, especially the strange rumors like "Sha Chun's Ghost". The folk music club and even the entire performing arts group spread a lot, and almost everyone was talking about it.
"I really heard the crying." Lu Xin, the administrative assistant of the folk music club, stayed to work overtime a few nights ago, and there were only her and two other administrative staff on the entire floor, "It's in the bathroom on our floor. I was so scared that I didn't dare to come out."
People in the folk music club would believe that Sha Chun was crying, but the serious crime team would never believe it.
Mingshu immediately asked Zha to monitor, but during the time period before and after Lu Xin entered the bathroom, the monitors closest to the bathroom and those farther away did not capture any suspicious behavior.
Fang Yuanhang said, "Master, all these monitors have blind spots. As long as you know where the blind spots are, you can avoid them."
"Yeah." Mingshu first stared at the surveillance, then looked at the layout of the entire floor, and said solemnly, "Check other surveillance. This person has anti-investigation awareness and knows the blind spots of surveillance, but TA may not know and can shoot. It's not just the surveillance near the bathroom that's going down the TA."
"Team Ming!" Zhou Yuan suddenly shouted, "Come here!"
The new building of the Performing Arts Group has a unique design and is quite artistic. The combination of mirrors and glass creates a sense of spaciousness and brightness. In the picture provided by the No. 4 camera located in the surrounding corridor, in the floor-to-ceiling window that was turned into a mirror by the night, a woman in a white veil costume walked slowly towards the bathroom before Lu Xin entered the bathroom.
That white veil costume was exactly what Sha Chun wore when he appeared for the last time.
