Chapter 12
Tong Yan was so frightened that she trembled all over, she couldn't help covering her eyes and screaming.

"Hurry up and call the police."

Zhang Xianxue woke up first, and hurried to the landline next to the TV cabinet.Next to the landline is a Samsung mobile phone that has been turned off, which is the mobile phone used by his wife.

Without thinking about it, he picked up the phone and quickly pressed three buttons: 110.

5:27
The piercing sound of sirens pierced the tranquility of the summer night. Three police cars drove directly into the yard of Zhang's house. Teams of well-trained policemen walked in quickly, sealed off the scene, took pictures and collected evidence, and inspected traces... opened.

According to the preliminary judgment of the on-site forensic doctor, the deceased died of oral potassium cyanide poisoning, and the time of death was about half an hour to within four hours. Because the air conditioner in the room was turned on too much, which affected the natural changes of the corpse, it was difficult to further determine specific time of death.

After testing, the small half cup of coffee on the small table in front of the deceased's bed contained excessive potassium cyanide.The coffee mug bears only the deceased's own fingerprints.

The details will only be known after the autopsy report comes out.

It was almost 05:30 in the morning when the police finished their work and took the body away, and the small building gradually became quiet.

"So you think your wife committed suicide?"

When Zhang Xianxue and Tong Yan were interrogated separately, Luo Zhe, the deputy head of the Municipal Criminal Investigation Brigade who was in charge of the case, walked back and forth in the interrogation room with his arms folded after listening to Zhang Xianxue's account of the whole story. After walking twice, he suddenly raised his eyebrows, staring at him and asking.

"Yes, I think she committed suicide. The matter is already obvious. She knew that I had a lover outside, but she was very angry. She couldn't think about it for a while, so she thought of committing suicide... Before she died, she called Tong Yan's residence. The phone call from her can also illustrate this point. Although I didn't delay for a moment after receiving her call, I drove home in the car, but I didn't want to be a step late..."

Speaking of this, Zhang Xianxue couldn't help but have red eyes, after all, they are a couple.

Luo Zhe frowned and said, "According to all the signs of the on-site inspection, the possibility of your wife's suicide is indeed very high. But there is one thing I don't quite understand. Potassium cyanide is a highly toxic compound, which is generally used in smelting, electroplating, Plexiglass manufacturing, photographic and chemical industries, and transportation and storage management all have very strict systems. Except for relevant professionals, it is difficult for ordinary people to get in touch. How could your wife..."

"Photography? You said potassium cyanide can be used for photography?"

"Yes, when photo studios develop photos, they usually use ferrous sulfate solution to develop first, and then use potassium cyanide solution to fix... Why, do you think there is something wrong?"

Zhang Xianxue hesitated for a moment, scratched the back of his head and said, "Maybe I'm too sensitive. What you said reminded me of a few things. I don't know if this is a clue."

"tell me the story."

"First, at around ten o'clock last night, my wife called Tong Yan's residence, and I was there at the time. I stood by the phone and listened to the voice on the phone. It was indeed my wife's voice. It’s just that the voice was a bit noisy, with the faint sound of rushing water mixed in, as if she was taking a bath or taking a shower while making a phone call in the bathroom. Second, every room in our house, including bathrooms and toilets, is equipped with telephone extensions. It's very convenient to answer and make calls. I can't figure out why my wife uses a mobile phone to make calls. Third, I'm not sure about this. I can only speak out my intuition. I glanced at the TV cabinet by accident, and saw that there seemed to be only the milky white telephone landline on the telephone stand. But when I called the police, I found my wife’s mobile phone there. Do you think it’s strange? strangeness?"

Luo Zhe frowned and said: "The points you mentioned are indeed very important. We have checked your bathroom, and it is clean and dry. The bath towels, shower caps and slippers have not been used by anyone. Absolutely no one has showered or showered in the bathroom for an hour."

Zhang Xianxue gasped and asked, "Is there something else hidden here?"

Luo Zhe glanced at him, did not answer directly, but suddenly asked: "You just said that before you met with Tong Yan last night, she visited your house, didn't you?"

"Yes, she came to my house to meet my wife at around 05:30 yesterday afternoon."

"Very good." Luo Zhe walked around the room with his elbows in his arms, and suddenly made a phone call, "Xiao Wu, did you visit Tong Yan's residence this morning? Did you find any miniature tape recorders?" , recorder or something like that? No? Did you notice that there is a garbage dump downstairs outside the window of her bathroom for the residents of the community to throw garbage? Yes? That’s great. What time is the Sanitation Office? Garbage collection? 06:30 in the morning?" He quickly glanced at his watch, "Fortunately, now I have an urgent task for you, go to this garbage spot right away, check all the garbage carefully, and see if there is any recording equipment. Time is running out , you can bring a few more people to do it."

After finishing the phone call, Luo Zhe lit a cigarette, pacing up and down while puffing out smoke rings while frowning with bushy eyebrows.

Not long after, the inquiry room was filled with smoke.

When he was on his fourth cigarette, his phone rang.

Xiao Wu reported on the phone: "Captain Luo, you are really good at predicting things. We found a miniature tape recorder in a garbage dump under the bathroom window of Tong Yan's house. The tape recorder was packed in a white plastic bag with a cartoon pattern on it. , there is still a cassette inside, but the tape inside has been pulled out and burned, leaving only an empty cassette.”

"Okay, Liang Mengqiu really didn't commit suicide." Luo Zhe's eyes lit up and he said excitedly, "Immediately arrest the suspect Tong Yan."

9:07
The suspect Tong Yan was quickly arrested and the first interrogation began.The following is Luo Zhe's reasoning based on various clues and evidence:

Tong Yan looks innocent, but she is actually a woman with vicious methods and ambitions.

After she got married with the multi-millionaire Zhang Xian, all she wanted was to force him to divorce, so that she could occupy the magpie's nest and become a rich wife.

It's a pity that Liang Mengqiu is not an easy woman to deal with, she refuses to divorce life and death, so getting rid of Liang Mengqiu has become the only shortcut for Tong Yan to realize her dream of being a rich woman.

To this end, she brilliantly directed a "suicide" case through careful planning.

At around 05:30 yesterday afternoon, Tong Yan went directly to Zhang's house after getting off the plane.

Maybe as she said, Liang Mengqiu really sent a text message to ask her to go, maybe she went looking for it by herself.

According to her confession, that text message has been deleted, which can no longer be confirmed.

Tong Yan had already called Zhang Xianxue and made an appointment to meet at her apartment after getting off the plane.

She expected that Zhang Xianxue had already left home at this time, so she went boldly.

Facing the arrival of her love rival, Liang Mengqiu received her with an unfriendly attitude.The two confronted each other, and after talking for a while, Tong Yan took advantage of the unpreparedness and suddenly took out a sharp knife and pressed it against Liang Mengqiu's throat.Of course, the strict security check at the airport could not allow Tong Yan to carry this sharp knife on her body early, and the tight schedule could not allow her to calmly go to the department store to choose the appropriate crime tool after getting off the plane, so this It is very likely that the murder weapon was prepared before she flew to travel and stored in the luggage storage at the airport.

Tong Yan has practiced aerobics, Liang Mengqiu has asthma, and has always been weak. In addition, it is unexpected, so it is not difficult for Tong Yan to hold, control, or even subdue the mistress of the Zhang family with a murder weapon.

Tong Yan took out a miniature tape recorder and forced Liang Mengqiu to read a passage she wrote on a note. This passage was what Liang Mengqiu said later in the "telephone call" "I'm a ghost and I won't let you go "if.

Then, she forced Liang Mengqiu to drink a cup of coffee mixed with potassium cyanide.Tong Yan is a photographer, so it is easy to carry a bag of potassium cyanide on her body.

Liang Mengqiu drank poisoned coffee, and soon died of poisoning under the watchful eyes of his rival.

Tong Yan dragged her body to the bed, wiped all the places where she might leave fingerprints and traces with a tissue, faked a suicide scene, turned on the air conditioner, put away the tape recorder, took Liang Mengqiu's cell phone, and left quietly.

Tong Yan confessed that she only stayed at Zhang's house for half an hour.

But according to speculation, she wanted to complete the above "work" in an orderly manner, and half an hour was obviously not enough, and she might stay at Zhang's house for longer.

When she and Zhang Xianxue met downstairs in the residence last night, it was around [-]:[-] in the evening.

It takes about 10 minutes to take a taxi from Zhangjia to Huayuan Community in the urban area.

Based on this, it is speculated that Tong Yan should have left Zhang's house between 06:30 p.m. and 45:[-] p.m.

But she was afraid that people would suspect the actual time, so she lied and said that she only stayed at Zhang's house for half an hour. The story of a pet dog wasting 10 minutes taking pictures.

In fact, she was unable to find her so-called "that woman", and there was not enough circumstantial evidence to prove that what she said was true.

After returning to the residence last night, Tong Yan flirted with her lover calmly, then hid in the bathroom under the pretext of taking a shower, and dialed her home number with Liang Mengqiu's stolen mobile phone.

When the phone rang, she deliberately asked Zhang Xianxue to answer it.

She knew that Zhang Xianxue had always acted cautiously, especially when he was at his lover's house, he would always check the caller ID first when answering the phone.

She also expected that Zhang Xianxue would not dare to answer the call.

Sure enough, when Zhang Xianxue saw that his wife's mobile phone number was displayed on the caller ID, he panicked and asked her to come out to answer the call.

While agreeing, Tong Yan turned on the miniature tape recorder she had prepared and put it in front of the phone, then ran out to answer the call pretendingly, and deliberately got close to Zhang Xianxue so that he could vaguely hear the voice coming from the microphone Liang Mengqiu wanted to find a voice for self-destruction.

Zhang Xianxue didn't know there was any fraud, and when he heard that his wife seemed to be thinking about suicide, he drove back immediately.

Before going out, Tong Yan borrowed the opportunity of changing clothes in the bathroom to put away the miniature tape recorder, destroyed the tape, put it in a garbage bag, and threw it into the garbage dump under the window.

She took Liang Mengqiu's cell phone back to Zhang's house, and put it back when Zhang Xianxue was not paying attention.

Because of this affectation, when Zhang Xianxue came home and saw his wife's body, he would logically think that Liang Mengqiu committed suicide by taking poison, and he would never suspect Tong Yan.

"However, a wise man thinks a lot, and he will make a mistake."

Finally, Luo Zhe sat in the interrogation room, looked down at the trembling Tong Yan and said, "During the whole process of committing the crime, you have been bold, careful, methodical, and accomplished very well, but in the end, you made a mistake." Fatal mistake. When you hide in the bathroom and make a tape recorder, in order to cover the sound of the tape recorder and not be heard by Zhang Xianxue outside, you deliberately forget to turn off the shower, so that the sound of running water covers the sound of the tape recorder. This One point, you designed it very cleverly, but you forgot that the sound of sprinkling water can overwhelm the sound of the tape recorder, but it can still be transmitted to the phone microphone through the mobile phone. Zhang Xianxue who was listening at first thought that Liang Mengqiu was on the phone in the bathroom. Later, after our police inspection, it was confirmed that no one had used the Zhang’s bathroom in the previous one to two hours. The mobile phone was Liang Mengqiu’s mobile phone, and the voice was Liang Mengqiu’s voice, but the sound of the shower running water mixed in the phone was not Liang Mengqiu’s. At home, there are only two possibilities: first, Liang Mengqiu made the phone call at a friend’s house or in the bathroom of a hotel, and second, the caller was not Liang Mengqiu at all. According to neighbors, Zhang’s house was brightly lit at that time, unlike no one at home. If Liang Mengqiu was still alive at that time, he would never have gone out. This leaves only the second possibility: someone stole Liang’s mobile phone and hid in a bathroom somewhere to make a call. But how could there be Liang Mengqiu’s voice on the phone? What? The only explanation is that the audio has been recorded in advance. From this, the police finally found a breakthrough in this murder case.”

Tong Yan didn't fully understand what the police meant until she heard the last word, she lost control of her emotions, pulled her hair with both hands, stomped her feet and shouted loudly: "No, no, I'm not a murderer, I didn't kill anyone, you guys are mistaken Oh, I didn't kill anyone...Xianxue, hurry up and save me, I was wronged, I didn't kill people..."

Luo Zhe looked on coldly, and said: "It's useless if you don't admit it. As long as the evidence is convincing, even a zero confession court can sentence you to death. That's it for today. If you confess, you will be lenient and resist strictness. Go down and think about it. I'll come back tomorrow." ask you."

"No, no, I was wronged, I did not kill..."

When being pushed down by two policewomen, Tong Yan let out two ghostly screams, and in a fit of anger, she turned her head to the side and fainted.

17:00
Zhang Xianxue was sitting in the blue sky coffee house, the afternoon sun shone obliquely through the floor-to-ceiling windows facing the street, he moved his position inward to avoid the sun shining on his body as much as possible.

Opposite him, across the narrow coffee table, sat a young woman in her thirties, with fair skin, her appearance was almost like a child's face.

She wears a pair of exquisite short-sighted glasses, with a demure and dignified demeanor, but it is quite different from Tong Yan.

The two sat facing each other, silently drinking the bitter coffee in their respective cups, and occasionally their eyes met in the air, showing a subtle and complicated expression.After a cup of coffee was finished, no one spoke. Perhaps for the two of them, eye contact was enough.

After an unknown amount of time, the woman looked at her watch, got up and said, "It's getting late, I should go. I've heard about your wife. Take care."

Zhang Xianxue's eyes were red, and he said with a little sadness: "The matter has been dealt with, and the murderer has been caught. I'm fine, don't worry." After watching the woman leave reluctantly, he couldn't take back his lost eyes for a long time.

After sitting quietly alone for about ten minutes, Zhang Xianxue got up to pay the bill, and was about to walk out of the coffee shop when several policemen suddenly poured in from the gate. The ones walking in the front were Luo Zhe, deputy head of the Criminal Investigation Brigade of the Municipal Public Security Bureau, and another person A tall, middle-aged man in plain clothes.

Luo Zhe blocked his way, showed him the arrest warrant, and said, "Mr. Zhang, I am sorry that you have been arrested. You have the right to remain silent. If you waive this right, what you say will become evidence in court for."

Zhang Xianxue's expression changed, and he froze immediately.

In the interrogation room of the Municipal Public Security Bureau, Luo Zhe pointed to the plainclothes man and introduced Zhang Xianxue: "This is Fan Zetian, the captain of our Criminal Investigation Brigade. He went on a business trip yesterday and only came back to the bureau this morning. He has learned about you in detail. After the wife's case, it was concluded that we arrested the wrong person in the morning, and the murderer was not Tong Yan, but you. So we invited you here."

Zhang Xianxue's face was pale, and he looked up and down the heavy-browed and tiger-eyed captain of the Criminal Investigation Brigade uneasily, and asked calmly, "Why do you arrest people indiscriminately? Be careful, I'll sue you."

Fan Zetian's face sank, and his eyes gleamed, as if all the evils in the world could not escape his piercing eyes.
