The physical evidence side has long since collected a series of evidence at Chen Xuexian's house, and brought all the information back to the General Administration for research.
Lu Junchi finished all the photos and the information of the on-site investigation, and then handed over the video to the sound laboratory of the object identification center.
At present, voiceprint recognition has been recognized as an identification method in the world.
The human voice is associated with the soft palate, tongue, lips, and teeth.
Those voiceprints are like fingerprints. Even if you deliberately imitate someone else's speech or lower your voice, the voiceprint displayed will still have inherent characteristics.
In the afternoon, the serious crime team finally got the comparison results during the lunch break. After voiceprint identification, the man's voice in the video was Qiu Jiarong's.
Several people in the office were working overtime at noon, and only Su Hui lay on the sofa.
The office at noon was full of the aroma of food, but he only ate a little something, and then said that he was sleepy, and after lying down for a while, there was no sound. Lu Junchi walked over to take a look, Su Hui was sleeping soundly at this time.
His whole body curled up, using a throw pillow as a pillow, and Lu Junchi put a piece of clothing on him. He seemed to be aware of it, his body moved, and he buried his face in his clothes, revealing only the long eyelashes and the little tear mole at the end of his eyes.
Lu Junchi made a silent gesture to the other people. In order not to disturb him, the discussion of the case turned into an online discussion.
Zheng Bai looked at the result and typed with a frown, "Qiu Jiarong, that stupid programmer? He doesn't look like a murderer at all."
Qiao Ze typed: "the murderer doesn't have the word murderer written on his face. Look at the way he fights, but he's not cowardly at all."
"But this recording has not been recorded in its entirety, and there is no subsequent fight, and it cannot prove that he is the murderer." Qu Ming turned to look at Lu Junchi, "Let's ask him again?"
Lu Junchi pressed a line of words: "Call over and ask first."
Just after the discussion here, the phone on the table suddenly rang, and in the quiet office, the phone ringing was a little abrupt.
Afraid of waking up Su Hui, Xia Mingxi hurried to pick it up as soon as it rang, and after listening to a few words, he raised his head and whispered to Lu Junchi, "Captain Lu, a middle-aged woman came to the police station and said There is a case report. She said that she is Qiu Jiarong's mother."
Hearing this, Qiao Ze jumped up from the chair, but pressed his hand on the keyboard to type: "I didn't expect that, does she have any clues?"
Qu Ming typed: "I'm not sure, does this mother want to kill her relatives righteously?"
It seemed that they had to listen to what the mother had to say before calling Qiu Jiarong over.
Lu Junchi closed the file in his hand and typed: "Qiao Ze, you go and take her to the interrogation room, I'll go there right away."
Qiao Ze took the order and got up immediately, and made an OK gesture to Lu Junchi.
Lu Jun walked to the sofa late and called Su Hui softly, "Mr. Su, get up."
Su Hui had been woken up by the ringing of the phone just now. At this time, he opened his eyes and squinted like a cat.
Lu Junchi had an illusion that he didn't have two cats at all, but three cats. And this one is the most beautiful, the most precious, and the most difficult to serve.
Su retracted his body. After a while, he rubbed his eyes and let go of the pillow: "What was the call just now? Has the case progressed?"
Lu Jun reported to him obediently: "Qiu Jiarong's mother is here, let's go over and ask."
Su Hui snorted, then got up and slowed down for a while. Lu Junchi poured him a cup of hot water and went to the interrogation room first.
When Su Hui passed by, Lu Junchi had already brought Qiao Ze in to ask.
Qu Ming called out, "Mr. Su."
Su Hui nodded and sat beside Qu Ming.
In the interrogation room, Lu Junchi looked at the middle-aged woman in her fifties. Her face was a little yellowish, her eyelids were swollen, and her hair was permed and slightly messy. The woman's dark circles are heavy, and she probably hasn't slept well recently.
It was the first time she came to the police station and faced the two policemen. Her hands were trembling and her expression was unnatural. She had been holding a bag tightly in her arms and seemed very nervous.
Lu Junchi looked at the registration form. This woman is called Qin Yiyun. She is fifty-six years old and lives in Huadu. She is currently retired at home.
Qiao Ze checked the information aside and asked her, "Auntie, can you tell us why you came to the General Administration today?"
Qin Yiyun sobbed, tears flowing from the corners of her eyes again, she covered her face with her hands: "I also mustered a lot of courage to come here... I... I really didn't expect that my biological son would be here because of A woman who has come to this point..."
Qiao Ze comforted: "Auntie, don't worry, speak slowly."
Qin Yiyun wiped the corners of his eyes, and then began to say, "I suspect that my son killed someone..."
Then she explained: "It's like this, my son Qiu Jiarong... He has always been shy, and he didn't find a partner when he grew up. After the age of 25, the old couple of us started to be anxious. All kinds of blind dates will be offered to him. This year, A few months ago, my son suddenly told me that he was in a relationship."
Qin Yiyun's speech was a little messy, but she wiped her tears and continued: "I was very happy at first, and our husband and I were very supportive, and I was thinking about when he would be able to bring the girl back to see. But I didn't expect, It was the beginning of a nightmare. Since then, he has been a little strange... Usually open and closed, he always told us about the girl, that she cooks deliciously, that she is virtuous, and when we started, we also It is normal to feel that the child is in love.”
"But the more I go on, the more I think he seems to be possessed. He doesn't care about work anymore. He often doesn't eat at home. When he comes back, he just looks at his phone. If the other party sends him a message, he will be happy like a child. Yes, once the other party ignored him, he started to restless. Until one day, he came back with a bruised face and wounds... He said he had a fight with someone outside... "
This is probably the time when Qiu Jiarong and Shao Changqing fought on the surveillance camera.
"I didn't know why at the beginning. It wasn't until after a while that he admitted to me that it was because of that woman that he fought with others. After that, he was even more obsessed and often didn't go home."
Then Qin Yiyun continued: "I persuaded him at that time that there are many women in the world, if that one doesn't fit, then change another one, but he said he wanted that woman. Once he drank some wine, he cried and told me , 'Mom, if she doesn't want me anymore, I don't want to live anymore.' After hearing this, I was horrified and quickly enlightened him."
Lu Junchi frowned as he listened, he remembered what Chen Xuexian said before. He feels that this man has been firmly controlled by Chen Xuexian, and maybe he is also under PUA, and has been controlled by that woman unknowingly.
"Later..." Qin Yiyun said here, gritted his teeth, "I have two suites at home, I live in one, and the other is a wedding room for my son. He lives alone, I I go to clean his house every once in a while, just recently, I once went to his house to clean the room, and found some blood stains on his clothes and shoes... They were all very small blood stains, maybe he didn't notice... I... I was very panicked when I saw it."
Speaking of which, she clenched the cloth bag in her arms even more: "I hesitated for a long time, should I discuss with my wife. In the end, I came by myself... "
Lu Junchi and Qiao Ze were both shocked when they heard this: "Auntie, did you bring your clothes?"
"I brought it here." Qin Yiyun took out a men's plaid shirt from the bag beside him, and handed it to Lu Junchi.
Lu Junchi checked it, and there were some bloodstains on the wrist that were not easily detectable. He thanked him: "Thank you auntie, we will carry out tests and comparisons."
If the bloodstains on the clothes belonged to Guo Chengfeng, then this would be an important evidence.
It is not easy for the mother in front of her to be able to report and expose her own blood relatives.
When Qin Yiyun said this, he covered his face and cried again: "I... I had been mentally prepared for a long time before I came here. I thought about whether to wash the blood off the clothes, and I also thought about whether to wash the clothes off. Keep this thing under wraps... But... But I can't... I don't want to watch him fall deeper and deeper. He... He's become more strange lately, I heard that he and the company have taken long vacations, often do not go to work, and He sometimes goes out with him, but there is a fruit knife missing from the knife holder at home. I am really afraid, I am afraid what will happen again, I am afraid that he will do something else and make a big irreparable mistake... "
Qiao Zejia asked, "Auntie, Qiu Jiarong didn't know you were here today, did you?"
Qin Yiyun nodded: "he shouldn't know. I came here without him... "
Lu Jun said lately: "Auntie, you are doing the right thing. We will pay attention to the clues you said. We will monitor his behavior."
Hearing this, Su Hui in the outer observation room frowned slightly.
Qiu Jiarong is still preparing to kill, will the killing continue
Who will be his target
The light rain last night swept away the gloom in the city, and when it was about to get off work, the office was a little quiet.
This is a high-end office building in the center of Huadu. In the investment company on the twenty-second floor, Shao Changqing sat in his office. identity of.
It was already past nine o'clock in the evening, and Shao Changqing took out the dinner he had brought.
It was a meat-stuffed dumpling. The dumplings were beautifully wrapped, with thin skin and large filling, revealing an attractive aroma.
Shao Changqing calmly went to the company's pantry and heated the dumplings in the microwave.
He brought his own vinegar, took out a plastic dish, poured the vinegar bag into it, and took a bite of a dumpling.
The aroma of meat overflowed in his mouth, he chewed it with satisfaction, and couldn't help squinting his eyes.
The personnel department is next door, and the director of personnel is also working overtime. At this point, everyone is hungry. He came over and said, "Mr. Shao, what are you eating?"
Shao Changqing said, "Dumplings."
The director of personnel said, "It smells so good."
Shao Changqing is proud: "That's natural, my wife made it."
The director of personnel smiled: "How long have you been in love? Before I sent my red envelope, my wife called me first." He swallowed and asked, "What kind of meat stuffing?"
"Pork and mushrooms."
The deliciousness of the gravy and the special fragrance of the mushrooms are particularly delicious.
In general, when the word arrives here, the other party will take the initiative to taste it, but Shao Changqing has no meaning at all. The director of personnel has not had time to eat breakfast, and he can't help smelling the smell. He pulled his face and said, "Can you give me a taste? "
Hearing this, Shao Changqing shook his head and covered the lid of the dumpling with his hand, looking reluctant: "You can eat whatever else, my wife's dumplings won't work."
The director of personnel said, "Stingy!" Then he returned to his office.
Shao Changqing was eating dumplings when suddenly the phone rang on the desk. The landline in the office is basically a decoration these days. He didn't expect anyone to call, and it was during the night of overtime.
Shao Changqing answered the phone, hummed a few times, and became more serious the more he listened: "Okay, I see."
After finishing the things, Shao Changqing looked at the dumplings in front of him, still reluctant.
In Huadu at night, it was past ten o'clock in the evening, the weather had already turned cold, it was a little stuffy today, the content of water vapor exceeded the standard, and it seemed that an autumn rain was brewing.
Shao Changqing, who had finished working overtime, took the last train out of the subway entrance. He was walking on the road and passed a somewhat remote alley when suddenly there was a sound of footsteps behind him, and a figure caught up with him.
"Who!" Shao Changqing looked back with some vigilance. The person behind him was about 1.78 meters tall, wearing a black hood and a mask to cover his face tightly.
The man pulled down his mask, revealing a man's face, it was Qiu Jiarong.
Now, the man's face was pale, and the elegance and dullness of the past were completely gone, replaced by a cold and cruel.
Shao Changqing looked at him, full of vigilance and vigilance: "You were the one who fought with me last time... The surnamed Qiu, what do you want to do?"
"I want to ask her about her." Qiu Jiarong's eyes looked around, it was pitch black, and his face became hideous, "I know, you must have hidden her! Give her back to me! "
The place was extremely quiet, except for the occasional meowing of wild cats on the side of the road. The air was almost freezing.
Shao Changqing shook his head: "I don't know where she is. She hasn't contacted me for a long time. In the end, you were with her!"
Qiu Jiarong was stunned for a moment: "Nonsense! You are talking nonsense! You clearly took her away!"
"The police are looking for her as well." Shao Changqing touched her nose and said, "I guess it's because you did something bad that caused her to escape?" His expression showed a hint of sarcasm, "You Didn't you keep saying that that woman loves you more? Why did you ask me where she is? If you came to me today, it was just to ask about this, but I didn't know at all."
"I don't believe your nonsense! Where did you get her?" Qiu Jiarong's face became hysterical, and he took out a knife from another pocket.
Shao Changqing looked at him and raised the corner of his mouth: "Mad, she doesn't want to be with a lunatic like you."
These words hurt Qiu Jiarong, he held the knife in his hand and stabbed Shao Changqing.
Shao Changqing was not afraid until this time, so frightened, he hurriedly dodged and called out, "Help!"
He wanted to escape, but his legs were weak, and after running a few steps forward, he fell to the ground.
The knife in Qiu Jiarong's hand slashed straight towards Shao Changqing.
As soon as Shao Changqing fell, the knife slashed in the air and made a swooshing sound.
