We returned to the school's office and re-sorted out Du Wanqian's case based on new clues.

The day Du Wanqian was confirmed missing was the 25th of last month.

According to the information that can be found so far, she escaped from home and her father in circles in the morning, and called an online taxi at the corner of the street and went straight to school. She wandered around school for about two hours before leaving the school gate.

The police had already retrieved surveillance data before, and Lin Ying still remembered that Du Wanqian had last appeared in a surveillance near Weiyang University, which was 2:45 p.m.

In the surveillance video, Du Wanqian's steps are light, she walks forward quickly and happily, and disappears after turning the corner - the surveillance of the road she turned into had a problem a few days ago, and no trace of her was found when she searched the surrounding surveillance.

We investigated Ran Zijin's class schedule and found that he had a class on the afternoon of the 25th, but he didn't show up in class because he had always been a full-time attendee.

At Lin Ying's request, the student office secretly called Ran Zijin's roommates to inquire, and they said that Ran Zijin did not actually live in the dormitory permanently, and he rented a semi-basement on Suzao Street in Zhuxia District. And today, he once again unexpectedly skipped class.

"Let's hurry to Suzao Street!" Lin Ying shouted angrily.

......

In fact, this morning, Ran Zijin was in class at school, but when the police car that appeared again after a long time drove into the campus, Ran Zijin suddenly had a strong premonition - this time something was really going to happen.

In a hurry, he didn't even bother to pick up his schoolbag, but slipped out of the classroom under the pretext of going to the toilet, escaped from the teaching building, and then took a taxi at the school gate, urging the driver to rush towards the rented house on Suzao Street.

He cared about the large bloodstain in the room.

Although he had been cleaned many times, he was still not at ease. He had recently looked up a lot of information and learned that there was a reagent called luminol, and no matter how clean you wiped the blood, you could show the original shape of the blood with a spray of this reagent.

He searched the Internet for ways to eliminate the luminol reaction and found that it could be cleaned with bleaching powder, but unfortunately the effect of the bleaching powder only lasted for a few days, and after a while, the luminol reaction would reappear in that place.

Planning ahead is the way to go.

So these days, he ran home every other day and carefully and carefully cleaned the blood-stained area with bleach.

The last time he cleaned it was yesterday, but today when he saw the police car, he suddenly panicked inexplicably. He hurried to the rented house in a car, opened another bag of bleaching powder and poured it into the basin, then put on plastic gloves and wiped the area again.

Just as he was struggling in the room, there was a soft knock on the door.

"Who?" He asked nervously, his voice trembling.

"Open the door, it's me."

He breathed a sigh of relief because it was the landlord's voice.

He quickly put away the bleaching powder and the things that mop the floor, and then walked cautiously and cautiously, first glancing through the cat's eyes.

Through the cat's eye, he saw the landlord's face, and the landlord was standing close, and he also looked inside through the cat's eye.

"Uncle, what's the matter?" Ran Zijin felt that his voice trembled a little.

"It's okay, the downstairs neighbor called, said that the ceiling was dripping, and asked me to come and see."

"Oh......" Ran Zijin looked back at the floor he was wiping - could it be that the water seeped downstairs?

He looked through the cat's eye and tried to continue to see what was going on outside, but the landlord was still standing there, his broad shoulders blocking the cat's eye.

Ran Zijin couldn't confirm whether there were other people around, in this case, he didn't open the door but there was a ghost, so he had to run over and bring the basin to the bathroom, then took off his gloves and quickly opened the door.

Ran Zijin unscrewed the lock in the house, but he didn't expect the landlord to come in, but a few strangers pushed the door in.

"Captain, it smells of bleach!" A young woman shouted.

"Check it out!"

"Wait!" Ran Zijin stretched out his hand to stop, "What are you doing?" ”

"Police." The woman at the head said lightly, "My surname is Lin, this is a search warrant, I hope you can cooperate with the investigation-Shi Chong, you talk to classmate Ran first!" ”

Ran Zijin only felt that his legs were weak, and he barely stood by holding on to the door frame.

At this time, he noticed that there was still a man and a woman standing outside, and they didn't seem to have any intention of coming in, and the woman was talking to the landlord about something.

Lin Ying walked around Ran Zijin's house before coming out, and she saw me and Shen Yu still standing outside the door, so she walked over in surprise and asked, "Why didn't you go in to investigate the scene?" It's not your style! ”

"What else are you looking at, it must be the place where Du Wanqian was killed, right? You don't have to enter the door to smell a lot of bleach, and it's like trying to cover it up. Shen Yu said.

But I know that she is actually a little worried, afraid that she will not find the "logical singularity" after she goes in, and her self-confidence will be hit again.

Fortunately, Lin Ying didn't ask much, she nodded and said, "It's suspected that the crime scene is right." This guy is smarter, and he scrubbed the ground with bleach, and the luminol reaction was indeed inaccurate, but there were no silver three hundred taels here, and he just exposed the specific place where the murder occurred, I just asked Shi Chong to pry open the wooden floor, and there are traces of blood that cannot be removed in the gaps between the floors, I believe that it is not so difficult to extract DNA. ”

"Did he confess?"

Lin Ying shook her head: "It's recruited, but he said that he didn't kill the person." ”

"What? What's going on? Shen Yu seemed a little surprised.

According to him, Du Wanqian was indeed invited by him to his rental house. You know, Miss Du is used to being willful, she is not afraid of heaven and earth, she didn't think much about it at all, and she ran directly over that afternoon. As a result, as soon as she entered the door, Ran Zijin punched her unconscious, and then tied her up.

Ran Zijin asked Du Wanqian why she had to poison An Yue, Du Wanqian was also a hard bone, and directly said that the old lady wanted her to die. Ran Zijin was furious and grabbed Du Wanqian's neck until she was dying. But Ran Zijin said that he didn't have the courage to kill, and he didn't want to kill her, he just wanted to kidnap and torture her, so that she could also experience An Yue's pain. ”

"Then how was Du Wanqian killed?"

The kid said he didn't know, and when he returned to the rental house that day, he found that Du Wanqian's throat had been cut, and there was a big pool of blood on the ground. He panicked and sat in the room thinking about what to do with the corpse for a long time. After thinking about it, he decided to check out the hardware stores on the surrounding streets, and he planned to buy an axe and machete, and wanted to dismember the body and throw it away. But when he returned home with a knife and axe, he found that the body was inexplicably missing.

He was startled, he first felt that his 'murder' had been exposed, and he stayed like a frightened bird for a day, constantly searching for news from the Internet.

When he saw the news that Du Wanqian's body had been found in Luqiao Park, he had been in a bit of a trance. He didn't understand the intentions of the man who stole the corpse, and he was always nervous.

"He wanted to move, but he didn't have the money to pay liquidated damages, he felt that the key to his house was probably stolen, so he quickly found someone to change the lock the next day, as for the blood stains on the floor, according to himself, he wiped it with bleach powder almost every two days, just in case the police came to investigate and could not detect the luminol reaction."

"This kid is stupid." Shen Yu sighed and said, "I guess I've read too many mystery novels - do you think his words are credible?" ”

Lin Ying frowned at us and said, "Come and see." ”

Shen Yu and I walked into the room. Ran Zijin's face was pale, and he was taking Xiao Yu to open the kitchen cabinet and take out a clean axe and firewood knife. I took the opportunity to take a closer look at his appearance, his face is well-proportioned and shapely, his eyebrows are clear, he is really a handsome guy, no wonder even the star-chasing and irritable woman Du Wanqian will be tempted by it.

Lin Ying walked over and examined the knife and axe, then stood up again and asked, "Where did you imprison Du Wanqian at that time?" ”

"It was in the open room, and I tied her to a chair. She kept swearing, so I grabbed a stinky sock and gagged her. I wanted to starve her for a few days, but I was afraid of starving her, so I came back every day before school and in the evening to stutter for her. I heard the news of her disappearance at school, and I was afraid of being suspected, so I had to stick to my old routine. That night, I was studying at school as usual, and when I heard the news of her disappearance, I was afraid of being suspected, so I had to stick to my old routine. That night, I studied at school as usual, but in fact, I was so panicked that I couldn't read at all, so I finally waited for the library to close before going home, and when I came back, she was killed in a chair, her throat was cut, and there was blood all over the floor. ”

"Where's the chair? What about the rope that binds people? ”

"Afraid of being discovered, I brushed the chair clean and then chopped it up with an axe and threw it along with the rope."

"Where did you throw it?"

"It's in the trash can at the corner of the street."

"Xiaoyu, call the company that collects garbage and look for physical evidence."

"But I really didn't kill Du Wanqian......" Ran Zijin suddenly cried, "I hate her, I hate her for pushing An Yue downstairs." But I really didn't kill her, I didn't have the courage, I didn't have the guts—if I had, I would have stepped forward and saved An Yue......"

"What?" We were all taken aback, "Du Wanqian pushed An Yue downstairs?" ”

Ran Zijin wiped his tears and looked at us in surprise.

"I thought you found out......"

"What the hell is going on?" Lin Ying asked, "How could it be that Du Wanqian pushed An Yue downstairs, and how could you see it?" ”

"Because I either followed An Yue or Du Wanqian those days, I was afraid that something would happen......"

"Wait a minute. Shi Chong, take the recorder. ”
