Approaching the plastic sheet, Gu Chen could already faintly smell a peculiar smell.

This sensitive sense of smell from the profession is often more accurate than that of ordinary people.

That's right.

Under the plastic sheet, there was indeed a corpse.

Officer Wang and Lu Weiwei came to Gu Chen's two sides respectively, put on gloves and masks, and began to pinch the sides of the plastic sheeting and gently uncover it.

At this moment, a young woman with a beautiful face was lying here quietly, as if she was asleep, but her expression was slightly painful.

Gu Chen began to examine the woman's physical condition and found that the woman's skin and mucous membranes were bright red.

After that, Gu Chen investigated the woman's other physical characteristics, and probably had the answer in his heart.

So Gu Chen looked around and began to look for other clues.

At the bottom of the big stone, Gu Chen found a lady's red bag.

But the strange thing was that the red bag was far away from the woman's body, so Gu Chen turned his head and asked Xiaohu: "Have you touched this bag?"

"Uh......"

Xiao Hu looked a little flustered when he heard Gu Chen's words.

"Yes or no?" Seeing that he didn't answer, Officer Wang reminded again.

Xiao Hu and the two companions glanced at each other, and then said hesitantly: "Yes...... There was movement, and at that time, because of the discovery of this body, we found that she was dead, and we were a little scared. ”

"But I saw that there was a small bag next to her, and out of curiosity, a few of us opened the small bag to see what was in it, so we ......"

"So you just went over the bag?" asked Lou.

Several people looked at each other again......

This time, everyone just nodded silently, but did not dare to make a sound.

Gu Chen stepped forward, took the red leather bag from under the big stone, opened the zipper, and found that there was a cup inside, as well as a handwritten notebook, and some cosmetics.

Gu Chen carefully placed these items one by one and numbered them for photos.

Then he took the glass in his hand, put it on the tip of his nose and sniffed it.

With the blessing of master-level observation, Gu Chen quickly discovered the abnormality in the cup, and his brows couldn't help frowning slightly.

"Senior Brother Gu. Gu Chen had an expression, and Lu Weiwei immediately noticed that she was tired.

"Toxic. Gu Chen said.

"That means the woman died of poisoning?" asked Lu Weiwei.

"Well, the woman's skin and mucous membranes are bright red and somewhat abnormal, and the signs of body poisoning are particularly obvious. ”

Hearing this, Officer Wang glanced at the three people who reported the crime.

Perhaps frightened by Officer Wang's gaze, Xiao Hu, who called the police, hurriedly waved his hand and defended himself: "Comrade policeman, this matter has nothing to do with us, we just happened to pass by and found that there is a fast plastic sheet here." ”

"What are you doing here early in the morning?" asked Officer Wang.

Another young man replied, "We were going to run a marathon recently, so we came here as a team to exercise, and every morning we would climb a mountain." ”

Seeing Gu Chen staring at the handbag, the man explained again: "We went to rummage through her bag, and we also wanted to see if there was a mobile phone or something like that, to see if we could contact her family, but we found that there was no mobile phone." ”

"Don't be nervous. Seeing that the man was trembling when he spoke, Gu Chen asked him to relax and not to have too much psychological pressure.

The man sighed and stopped talking.

What Gu Chen is most worried about now is that he can't find his ID card in his handbag, and he can't identify the woman's identity for the time being.

And the water cup containing poison was obviously the key to the woman's death.

"Huh?" Lu Weiwei followed Gu Chen's example and confirmed the water cup twice: "A taste of bitter almonds, how could she not know that it is poisonous?"

"Don't smell it. Seeing that Lu Weiwei was learning from herself, Gu Chen hurriedly stopped: "It's potassium cyanide, it can be poisoned if inhaled in small amounts, and skin contact may also cause poisoning." ”

"Potassium cyanide?" Hearing Gu Chen's words, Xiao Hu and the other two companions were also dumbfounded.

The heart said that this young policeman, just by smelling it, he knew what was in this water cup?

One of the men stepped forward and asked Gu Chen weakly, "Comrade policeman, this potassium cyanide is very powerful?"

"Hmm. Gu Chen just nodded slightly and explained: "Potassium cyanide is deliquescent in moist air and releases trace amounts of hydrogen cyanide gas. ”

"Hydrogen cyanide has the smell of bitter almonds, is very easy to diffuse, and is easily soluble in water to form hydrocyanic acid. ”

"No wonder. When the man heard this, he also said by luck: "No wonder it smelled just now, but fortunately I didn't touch it." ”

Gu Chen glanced at a few residual liquids in the cup and said, "Cyanide is generally colorless crystals, which are easy to deliquescent in the air and have a faint smell of hydrogen cyanide, which can make the water produce almond odor. ”

"So it's right that you didn't touch it, but for the sake of insurance...... Gu Chen glanced at Yuan Shasha beside him and said, "Xiao Yuan, take your water cup and wash their hands for them, just in case." ”

"Good. When Yuan Shasha heard this, she went directly to her own kettle and reminded: "Come here, I don't have much water, you better be glad that you don't touch potassium cyanide." ”

"Ugh. ”

Several men looked at each other.

Hearing Gu Chen say this just now, he was a little scared, and hurriedly came to Yuan Shasha's side one by one, ready to wash his hands.

Xiao Hu asked Gu Chen curiously: "Comrade policeman, if your hands come into contact with potassium cyanide, can you wash them with water?"

"How do you say that?" Gu Chen didn't want to mention it originally, but considering that a few people might inadvertently come into contact with a cup of water containing potassium cyanide.

If you don't take precautions properly, you can cause harm to your body.

So he turned around and solemnly explained to a few people: "You all listen, potassium cyanide can't be touched, you should avoid contact, if you do, it is recommended to rinse it with water immediately." ”

"When you go back, you can also add a little hand sanitizer and use a toothbrush to help you wash it off. ”

Several people nodded silently, mainly because there was a female corpse lying in front of them, and the death of the female corpse was the best proof.

Therefore, several people were afraid of death, and when Gu Chen said this, of course everyone had to be obedient and do as they were told.

Xiao Hu Zhan who called the police said tremblingly: "This thing is really so terrifying? If you accidentally touch it, I mean carelessly, is it okay to clean it like this?"

Gu Chen glanced at him, and said seriously: "You should know that potassium cyanide, a white spherical hard lump, or granular and crystalline powder, is highly toxic. ”

"In moist air, deliquescent and release trace amounts of hydrogen cyanide gas, soluble in water, slightly soluble in alcohol, and the aqueous solution is strongly alkaline and quickly hydrolyzed. ”

"Anyone who touches a wound on the skin or inhales a tiny amount of powder can be poisoned to death. When it decomposes in contact with acid, it can release highly toxic hydrogen cyanide gas, and when it is mixed with chlorate or sodium nitrite, it can even explode, so you say horror yourself?"

"Uh......"

Seeing that Gu Chen said it so clearly, Xiao Hu could only nod fiercely.

It can be said that Gu Chen gave him chemical knowledge, so that he knew it in his own heart.

Seeing that the boiling water in Yuan Shasha's water cup was not enough, in order to save his life, Xiaohu asked again: "Then do you still have water?"

Lu Weiwei paused for a moment and asked Gu Chen and Officer Wang, "Senior Brother Gu, Lao Wang, do you have water in the water cup you are wearing?"

"I'm only half. Gu Chen said.

Officer Wang also said: "I have two-thirds. ”

"Give it all to Xiao Yuan. Lu Weiwei said.

Subsequently, Yuan Shasha directly took out the water cup from the belt accessories of the two, called a few people aside, and washed their hands again.

After learning about the dangers of potassium cyanide, several teenagers here began to wash their hands desperately to sign up.

On the other side, after Gu Chen took a photo of the woman, he sent it to He Junchao in the office, asking him to help determine the woman's identity as soon as possible.

Then he took the handwritten notebook and sat cross-legged on one side to flip through it.

"The handwriting is not bad. Seeing the woman's soft handwriting, Gu Chen couldn't help but look through it a few times.

It was found that they were all hand-copied by the woman in some verses and prose phrases.

What surprised Gu Chen was that the content of these poems was related to death.

In particular, there is no shortage of poems that praise death.

In Gu Chen's opinion, this is very abnormal in itself.

"How could a normal person pick up such a thing?" Gu Chen hesitated for a moment and glanced at the woman beside him.

Lu Weiwei also leaned on Gu Chen's side and copied the poems with the reader.

If at the beginning, Lu Weiwei was just admiring the woman's handwriting, but later, Lu Weiwei also found a big problem.

The woman's poems are sad, and she doesn't seem to have the slightest longing and attachment to life.

As Lu Weiwei, who has a good reading comprehension, there are only two words that she understands from these poems, that is, "disappointed".

"This is too pessimistic, isn't it?" Lu Weiwei shook her head, and couldn't help but say: "Is she a person with a heart disease? How can the poems excerpted are all some negative energy and extremely pessimistic poems?

"Maybe it has something to do with her own experience, right?" Officer Wang is not able to judge the woman's situation at the moment, so he can only talk about his own opinion based on excerpts from the poem.

Then the two of them set their eyes on Gu Chen.

Lu Weiwei asked, "Senior Brother Gu, what do you think?"

"There seems to be a bit of pessimism in it, but at the moment I think the most important thing is to figure out who she is and see what the situation is. ”

After a pause, Gu Chen asked Lu Weiwei: "By the way, Senior Sister Lu, is there any contact with the Technical Department of the Municipal Bureau?"

"We just communicated, and they will send someone over soon. Lu Weiwei said.

Gu Chen nodded slightly: "Then it depends on the progress of Senior Brother He's side." ”

After examining the corpse, Gu Chen and everyone reached a consensus.

The woman died of poisoning, and the poisoning substance was potassium cyanide.

However, in order to determine whether there were any other deaths caused by this, they had to be brought back to the technical department of the city bureau for a more comprehensive test.

Since He Junchao did not reply for the time being, Gu Chen and Lu Weiwei made oral registration of those men and recorded the identity information of several people.

And when the technical department of the city bureau sent someone to pretend to carry the body, He Junchao finally called.

Gu Chen didn't say a word, and directly opened the answer button: "Senior Brother He, how is the investigation?"

"Your photo, I checked for a long time, and finally found a few similar faces, and then after technical deletion, and location attribution, I finally found a person with a high degree of matching. ”

"See, listen. Gu Chen said.

"Hmm. He Junchao coughed dryly twice, and then couldn't help but say: "This woman's name is Zhuang Qing, and she currently lives in an apartment she bought, and she is a widow. ”

"A few years ago, his husband was killed in a car accident on the highway on a business trip, and now he seems to be alone. ”

"That's all?" Gu Chen thought that Junchao would continue to say, but he didn't expect it to be the end.

He Junchao said: "Yes, that's all that can be found at present." ”

"Then where is the specific place where she lives?" Gu Chen asked again.

"In Golden Harvest Apartments, Building A...... 1102。 He Junchao said.

"Okay, we'll go right now. ”

Gu Chen hung up the phone and looked around.

After making sure that there were no other valuable clues, Lu Weiwei, Officer Wang and Yuan Shasha were called, and they hurried towards Jiahe Apartment together.

Jiahe Apartment, which is one of the earliest developed real estate projects in Jiangnan City, is located in the center of Jiahe business district, consisting of two twin buildings, which are located on both sides of the road.

Downstairs is a bustling business district with a variety of gourmet shops.

When Gu Chen came to the door of room 1102 in Building A, he knocked on the door of the room.

However, as Gu Chen imagined before, no one in the house responded, which just verified He Junchao's statement, it may be that he lives alone.

So Gu Chen knocked on the doors of several other residents on the same floor one after another.

Only the door of the next room was opened with a "creak", and a middle-aged woman walked out.

She looked at the people in front of her carefully, and asked curiously: "May I ask the police comrade, who are you looking for?"

"Does this person live here?" Gu Chen opened the photo album on his mobile phone and showed her the picture of the woman taken at the scene.

The middle-aged woman frowned slightly, and then said, "Yes, her name is Zhuang Qing, and she lives next door to me." ”

But she felt that the photo in Gu Chen's hand was a little wrong, and she hurriedly asked again: "What's wrong with this Zhuang Qing?"

"She was found dead this morning on duty next to the lake. Lu Weiwei told directly.

The middle-aged woman covered her mouth with her hands, her face frightened: "She...... She's dead?"

But soon, her face calmed down again: "She's finally dead." ”

"What do you call that?" A little I didn't understand what the middle-aged woman meant, Lu Weiwei frowned slightly, feeling that it was not authentic to speak like this, right?

Perhaps realizing that she was a little out of shape, the middle-aged woman hurriedly explained: "I'm sorry, comrade policeman, I felt that Zhuang Qing was tired of life before, and I felt that she was depressed every day, and she might do something stupid." ”

"And I tell you, since her husband died, she has been very depressed, and she is deeply depressed, and she has to rely on medication every day. ”

"Many times, I am afraid that she will not be able to think about it, because she is a person who does not like to contact people very much in recent years, and rarely goes out. ”

"So that's the case?" After understanding why the middle-aged woman reacted like this, Lu Weiwei nodded silently, and asked casually: "Then she usually doesn't go out, what is she doing at home alone?"

"Maybe it's knitting sweaters and embroidery, I think she still likes these, but her personality is too withdrawn and she often goes to the psychiatrist. ”

Looking at Gu Chen, the middle-aged woman also confessed: "So when I heard you say this just now, I remembered that this is the reason, because she has been like this for the past few years." ”

"Is there a time when it gets better?" Gu Chen asked again.

"Better?" the woman didn't quite understand.

So Gu Chen said again: "It means that we didn't care about being depressed before, but now recently, has she ever been extremely depressed and has a little suicidal thoughts?"

"Uh......" The middle-aged woman was stunned, thought carefully for a few seconds, and then shook her head: "Aren't you embarrassing me?" I don't know her recent state, and I haven't greeted her for a long time. ”

"I'm usually busy with going to and from work and family chores, so I don't pay much attention to this neighbor. ”

"Okay. Gu Chen glanced at the gate of Zhuang Qing's house, turned his head and asked, "Then does she have any relatives in Jiangnan City?"

"Relatives?" The middle-aged woman was stunned for a moment, and quickly nodded: "It seems that there is an elder brother who is in ...... I work for a nearby renovation company, and I usually come to the apartment to see her, so I think it's the closest person to her. ”

"Because in the past few years, Zhuang Qing's big and small things, including seeing a psychiatrist, are all his brother in Zhang Luo, you can go and find it. ”

"Thank you. Getting a relative who could contact Zhuang Qing, Gu Chen was suddenly a little excited.

So he asked, "Do you know which decoration company it is?"

"Wait a minute. The woman quickly turned around and ran into the living room.

It didn't take long to hear a stirring in the fruit box in the living room, and a middle-aged woman came out with a business card: "That's it, Hongsheng Decoration Co., Ltd., his brother is a designer in it, you should know if you go there and ask." ”

"Thank you very much. ”

"You're welcome, why don't you make a phone call and ask her brother to come over, and you come to my house to sit down?"

"No, thank you for your kindness. ”

Although the middle-aged woman was polite, Gu Chen still declined.

So a few people came to the elevator door, took out their mobile phones, and dialed Zhuang Qiang's phone number according to the contact number on the business card.

It didn't take long for a man to respond on the phone: "Hello, who?"

"May I ask if it's Mr. Zhuang Qiang?" Gu Chen asked him.

The man said, "Yes, I'm Zhuang Qiang, may I ask who you are?"

"I'm Gu Chen, the captain of the criminal investigation team of the Furong Branch, and I have something to confirm with you. Gu Chen also reported to his family.

As soon as he heard about the police station, Zhuang Qiang asked hesitantly: "Comrade policeman, did that guy Liao Gang ask you to come to me for trouble?" I tell you that the contract was signed by himself, and I made all the circumstances clear to him at that time, but just like that, it is too hard to accuse me of fraud, so you can find him if there is something, don't bother me." ”

As soon as Gu Chen connected the phone, there was a burst of complaints from Zhuang Qiang.

Gu Chen smiled lightly and said, "Mr. Zhuang, I think you misunderstood, I am looking for you about your sister Zhuang Qing." ”

"Zhuang Qing?" Hearing that it was not a worry about his work, Zhuang Qiang suddenly seemed to have changed his face, and replied with a light smile: "I'm sorry, comrade policeman, I was too excited just now, mainly because my recent work is too bad, don't mind." ”

"I don't mind. Gu Chen said.

Zhuang Qiang asked again: "Then may I ask Officer Gu, what's wrong with my sister?"

"She's dead. Gu Chen said.

......
