Qin Shen walked to the interrogation table and sat down, spreading out the black folder in his hand, facing Lu Yajun. Xu Man sat on the chair next to him, moved the laptop on the table, and opened a new document.
Faced with such a situation, a hint of nervousness flashed in Lu Yajun's eyes. It seemed that she sensed a slightly unusual atmosphere, but she still behaved politely and calmly. With the same smile as before, she opened her mouth and said hello to Qin Shen.
Qin Shen did not respond to her. He brushed his fingers along the edge of the folder, turned a page, lowered his head and asked, "Lu Yajun, a fifth-grade student at Yongqiao Central Primary School, a classmate of Zhang Xiaojuan?" The end of his voice rose slightly, but he asked in a low voice, which gave people a sense of majesty.
Lu Yajun nodded.
Qin Shen: "Do you know your ID number?"
Lu Yajun thought for a moment and fluently reported a string of numbers.
Xu Man was a little surprised. This information had actually been found out last night. Asking now was just going through the process. No one expected a fifth-grade student to know it, but Lu Yajun reported it word for word, which was exactly the same as what they found out.
It seems that she has a good memory, no wonder she is an excellent student.
Qin Shen's expression remained unchanged as he continued to ask, "Where do you live? How many people are there in total? Who do you live with?"
Lu Yajun: "I live at No. 203, West District, Jiahua Villa Garden. I live with my parents and grandfather. There are four of us in total."
After she finished speaking, Qin Shen pulled out an A4 paper with an image printed on it from a folder, put it on the table and pushed it to her side: "Do you know the person on this?"
Lu Yajun looked down and nodded: "I know him, he's my grandfather."
Qin Shen: "What kind of job does your grandfather currently do?"
Lu Yajun: "No job, he is retired and resting at home."
Qin Shen: "What does he usually do?"
Lu Yajun: "I didn't do much, just made some small gadgets and stuff, and sold them occasionally."
Qin Shen: "What gadget?"
Lu Yajun: "Wooden chairs, wooden stools, etc..."
Qin Shen: "Have you been doing it all the time? How much time do you spend on it every day?"
Lu Yajun: "He used to do it for a longer time, but one time he accidentally scraped his finger and went to the hospital. My parents stopped letting him do it. Now he basically stays at home and rarely goes out. My father said that he wants him to enjoy a peaceful and comfortable life in his old age."
Qin Shen: "Stay at home all the time and never go out?"
Lu Yajun: "I will go out for a while after lunch and dinner."
Qin Shen: "What are you going to do?"
Lu Yajun: "... Chat with the old man you know."
Qin Shen: "Besides this?"
"……"silence.
While Qin Shen was questioning, Xu Man was not idle either. She was typing quickly on the keyboard, writing down what the two were saying. Lu Yajun's sudden silence made her pause in typing, and she looked up from the computer screen and looked across.
Lu Yajun lowered her head and looked at the picture on the table without saying anything. It was not until Qin Shen asked her again that she slowly said, "I... I don't know."
Qin Shen looked at her and didn't ask any more questions. He put the paper aside, took out the second piece of paper with a picture printed on it from the folder, and pushed it over. "Do you know the person above?"
Lu Yajun's face changed the moment she saw the paper, as if half a tube of blood had been drained out of her, and she turned pale.
She stared at the paper without saying anything.
"Do you know him?" Qin Shen asked for the second time, his voice lower than before, sounding more serious.
“……”Still silence.
"Do you know him?" for the third time.
"Recognize, recognize him." Lu Yajun answered in a low voice. At this moment, she finally lost her previous calmness. Like a normal child, she shrank her body when facing the majestic adults, lowered her head and spoke carefully.
Qin Shen: "Who is it?"
Lu Yajun: "Yes...my grandfather."
Qin Shen: "What is he doing?"
Lu Yajun's voice became even softer, with a faint hint of tears in her voice, "...picking up trash."
Qin Shen: "Why do you want to pick up trash?"
Lu Yajun: "Because he likes to do this, picking up things and selling them for money."
Qin Shen stretched out his hand and pointed at a spot on the paper: "Do you know what your grandfather is holding in his hand?"
Lu Yajun nodded: "Bag."
Qin Shen: "What is it used for?"
Lu Yajun: "Picked up the trash... and put it in."
Qin Shen: "Where do you usually go to pick up trash?"
Lu Yajun: “Near the community.”
Qin Shen: "What else?"
Lu Yajun pursed her lips and said after a few seconds: "Park."
"What park?"
“Wetland Park.”
Qin Shen stopped his series of questioning this time.
He turned over another page of the document, took out the third picture from it, and pushed it in front of Lu Yajun.
"Do you recognize the things on this bag?"
Lu Yajun stared at the third picture.
It was a black and white print, an enlarged version of a portion of the second picture. It was blurry, but something could still be made out.
A hand like a dead vine or charred wood was clutching a snakeskin bag. The opening of the bag was slightly loose, revealing a hint of light color inside.
She stared blankly, her face pale.
Qin Shen looked at her and said calmly: "Do you have anything else to tell us?"
Lu Yajun finally explained the whole truth of the matter.
On July 2, Zhang Xiaojuan came downstairs to find her during the break and showed her the automatic piggy bank that Lu Meiqin gave her. She was very surprised because this prize was a special prize and it was difficult for ordinary people to get it, so she asked her how she saved up enough stickers and how long it took her to save them. Unexpectedly, Zhang Xiaojuan replied that this was not a prize but an apology from the teacher because the teacher accidentally pushed her to the ground during class, so the piggy bank was given to her as an apology.
Lu Yajun's family conditions were not bad, but her parents were strict with her and never allowed her to play games or read books. Their pocket money was also strictly controlled, so she didn't have a piggy bank. When she saw the piggy bank in Zhang Xiaojuan's hand, she was a little envious and wanted to take it to play with it. Zhang Xiaojuan let her play with the piggy bank, but since neither of them had any money on them, she could only fiddle with the password setting disk, which was not fun at all. In this case, Lu Yajun suggested that Zhang Xiaojuan come to her house after class to play with the piggy bank.
Of course Zhang Xiaojuan readily agreed to this, because they had already agreed to visit Lu Yajun's home tomorrow, so there was nothing wrong with doing it a day earlier. Lu Yajun's English class ended later than Zhang Xiaojuan's dance class, so Zhang Xiaojuan went downstairs first after the dance class and waited in the square until Lu Yajun came downstairs after the English class. Then the two of them took the bus together and went to Lu Yajun's home.
Since it was Thursday, Lu Yajun's parents were both at work and her grandfather was out picking up trash, so there was no adult at home. Lu Yajun took out her pocket money and started playing with the piggy bank with Zhang Xiaojuan in the living room. When they lost interest, they played other games and did not stop until they both felt tired.
At this time, Zhang Xiaojuan said she was thirsty and asked if she had any water. Lu Yajun remembered that there was a leftover fruit platter from last night in the refrigerator, so she took it out to treat Zhang Xiaojuan. Because the apples had been eaten last night, she took another whole apple, cut it into pieces with a knife, mixed it with the salad dressing, and shared it with Zhang Xiaojuan.
Everything was fine. It was just an ordinary gathering of friends. Zhang Xiaojuan stayed at Lu Yajun's house until almost four o'clock and was ready to go home. She took the money out of the piggy bank and returned it to Lu Yajun, but Lu Yajun counted it and found that ten yuan was missing. She searched the piggy bank and the living room but couldn't find any trace of the banknotes, so she suspected that Zhang Xiaojuan had hidden them.
Zhang Xiaojuan naturally denied it and argued with reason. Lu Yajun wanted to search her body, but she refused. The two of them started arguing, and when Lu Yajun got angry, he took the kitchen knife he had just used to cut apples and chopped Zhang Xiaojuan from behind.
With one cut, blood splattered everywhere.
Lu Yajun was horrified. She didn't expect such serious consequences. After the first few seconds of silence, Zhang Xiaojuan realized what had happened and started crying loudly. Her crying stimulated Lu Yajun, prompting her to cut Zhang Xiaojuan with the second knife - which was also the fatal one.
"...I don't know what I was thinking at that time, I was just...I was very angry and scared. I was afraid that she would tell her parents, and that they would know about it and punish me, so I...I chopped it down..." Lu Yajun cried as she spoke, and when she got to this point, she was already sobbing.
Qin Shen was not affected by her emotions at all, and continued to ask calmly: "Did you realize at the time that this knife might kill Zhang Xiaojuan?"
Xu Man was stunned. What did he mean? It is obvious that Lu Yajun committed murder in passion. She lost her mind due to anger and killed others out of control. Did he ask this because he thought there was some hidden story? Could this be a premeditated murder?
Lu Yajun hunched her shoulders and answered with a twitch: "I... I don't know... I don't remember... I only know that when I came to my senses, she... she had fallen to the ground, looking at me with her eyes open..."
Qin Shen: "What happened next? How did you deal with the body?"
"Later... Grandpa came back..."
Just when Lu Yajun was horrified by Zhang Xiaojuan's death, Lu Yajun's grandfather returned home and was shocked to see the blood all over the living room. However, after learning that his granddaughter had accidentally killed her classmate, he did not call the police. Instead, he chose to keep the matter secret for his granddaughter. He divided Zhang Xiaojuan's body, transported them in batches to the wetland park, and buried them in the soil deep in the woods.
Lu Yajun's grandfather had worked as a carpenter for several years and was quite strong. Zhang Xiaojuan was a child and had not yet grown up, so it was not very difficult for him to dismember the body. The process of disposing of the body was even simpler. He put Zhang Xiaojuan's body parts into four garbage bags, and stuffed them two by two into the snakeskin bags used for collecting garbage. He then took the iron tongs he usually used for collecting garbage, and carried them to the wetland park. After two trips back and forth, he buried them all.
Since he often picked up garbage outside with a snakeskin bag and an iron clamp, and went in and out of the wetland park at least two or three times a day, when the park security guards saw him carrying a snakeskin bag in and out, they thought it was a very normal thing and did not think about anything else. Even when a body was found in the park the next day, and the police asked if there were any suspicious people entering and leaving the park in the past few days, they did not suspect him.
Afterwards, the grandfather and grandson cleaned up the living room together, and a murder and corpse disposal case was completed.
