"I'm here to investigate, not to collect evidence!" Zhao Yu's nonsense came as soon as he opened his mouth, "Where to wear gloves? Don't worry, your daughter is not Sherlock Holmes, you can't see it!"

After speaking, he ignored the old man's objections, reached out and grabbed a book. Pen ~ fun ~ pavilion www.biquge.info

It was a book about anesthesiology, and Zhao Yu casually flipped through a few pages and found that there were still a lot of notes in the book.

Li Dan's handwriting is delicate and neat, without any alterations. It can be seen that she should be a thoughtful and logical person.

Zhao Yu flipped through a few more books, all of them. So, he couldn't help but ask the old man at the door: "Has your daughter ever studied medicine? Why are there so many books related to medicine?"

"No, no," the old man replied affirmatively, "she only worked in the pet clinic many years ago, and it was the famous Dr. Lu's veterinary shop, and Dandan worked as an assistant to them!

What the!?

Pet clinic?

Veterinarian shop?

Zhao Yu was shocked in his heart, the anesthetic used by the murderer in the chopping case was an animal agent, and the source of this medicine happened to be a veterinary shop!

It's no longer a coincidence, is it?

Could it be that this Li Dan ......

Zhao Yu put down the book and scanned the entire room again. For some reason, he always felt that there might be something more important to be found in this room.

"Old lady!" Zhao Yu thought for a while and asked, "Is your home online?"

"Yes!" replied the old man, "I am useless, but my daughter is useful!"

"What about computers?

"My daughter has a notebook, and she always carries it with her, so she shouldn't be here. ”

"Then ......," Zhao Yu pointed to the room and said, "She doesn't have a writing desk in the room, how can she usually play with the computer?

"Yes, it's just lying on the bed and playing!" said the old man without reservation, "not only playing with the computer, but also writing on the bed when my daughter reads and writes a word." Oh...... By the way, under her mattress, there are a lot of blank sheets of paper, and I often see her writing on them, and there are so many photos!"

Oh!

Zhao Yu nodded, and suddenly, he suddenly came back to his senses!

"What!?What are you talking about??under the mattress?" Zhao Yu was startled, his eyes widened and asked, "Above...... What is written on it?"

"I ...... I just saw it a few times, I ...... My daughter didn't know I knew...... She knelt on the bed board and wrote very seriously...... I...... I only saw it through the crack in the door!" The old man was so frightened that he was incoherent, and he didn't know what to say.

Yes!?

Zhao Yu didn't ask any more questions, strode to the bed, and reached out to lift the mattress and sheets on the bed.

"Officer!" the old man was frightened, and rushed over directly to stop Zhao Yu, "My daughter has a habit of cleanliness, this sheet ...... My daughter's eyes are very poisonous, no matter how she cleans it up, she will definitely be able to see it!"

"Old lady!" Zhao Yu shouted excitedly, "When is it, you are still thinking about your daughter's cleanliness! Let me tell you, these things written by your daughter may be those things that can kill her, you ...... You're still holding back?"

Seeing Zhao Yu so excited, the old man realized that the stakes were high, and finally reluctantly let go of Zhao Yu's arm and honestly retreated.

Zhao Yu grabbed the corner of the mattress, brushed it, and pulled the entire mattress high.

After tearing it open, a scene that appeared on the bed board made Zhao Yu couldn't help but be surprised!

But when I saw that the flat bed board was covered with white paper glued together, the white paper was densely filled with many words, and there were many photos, pictures, and photocopied or printed documents pasted on them!

The scene in front of me is like a whiteboard used by the police to analyze the case. It's just that this thing is more detailed and meticulous than the police whiteboard! The amount of information it covers is much larger than that of the police!

Grandma a bear!!

At that moment, Zhao Yu's heart was beating wildly, his blood was swelling, he didn't need to look at those words carefully, just by relying on the photos on the white paper, he could already be completely and truly sure that the goddess prodigy Li Dan was the real murderer who chopped the case!!

But the photos of Gao Tian, Yuan Lili, Luo Meina and others are all pasted in eye-catching positions, and all their information is recorded with a black pen next to them. Obviously, Li Dan has done a very detailed investigation of them.

Zhao Yu rolled the mattress aside, and carefully looked at the beginning of the white paper, but under Gao Tian's photo, there was also a black and white photo printed out with a printer, which showed the vent of a ventilation duct.

Looking at the following, the date, location and other information are also marked in detail, which is completely consistent with the situation of Gao Tian being chopped up.

It can be seen that Gao Tian's hand was chopped off by Li Dan!

Ahh

Zhao Yu summed up this information, and he was able to completely connect the process of chopping the case. When he finally figured out the modus operandi used by Li Dan, he couldn't help but be deeply shocked again!

Li Dan's plan was so meticulous that it was unbelievable, it was seamless! Before deciding to do it to Gao Tian and the others, she had even made careful preparations several months in advance.

Take Gao Tian as an example, Li Dan knew early on that Gao Tian was going to come to Qinshan to listen to a concert, and knew her seat number.

She even knew that after the concert, Gao Tian would inevitably go through the underpass, and there was no camera in that underpass.

Because Gao Tian's seat was at the front, when he left, he would naturally line up at the back of the crowd, which gave Li Dan a better chance to get off.

Zhao Yu estimated that Li Dan should have also bought a ticket to enter the venue, and then followed Gao Tian all the time.

When the concert ended and Gao Tian entered the passage, Li Dan stunned her while others were not paying attention, and then dragged her to the unnoticed power distribution hut in the passage, where she was anesthetized and chopped!

The most desperate moment came, after committing the crime, Li Dan did not run away in a hurry, but came to the wind room on the other side of the passage.

The wind room is the place where the underground facilities of the stadium are supplied with air, where there are several ventilation ducts leading to other places. Li Dan waited until dawn before he got into the ventilation duct, and then left through the exit of the gymnasium's sanitation department according to the pre-planned route.

When she left, it was just when the sanitation workers went to work, and she had already prepared a sanitation worker's costume and left the gymnasium while there were many people. Later, no matter how powerful the police officer who was in charge of viewing the surveillance video, it was absolutely impossible for him to notice this.

What's more, in order not to make the surveillance video suspicious, she actually prepared a container containing formalin in the ventilation duct early in the morning, hid Gao Tian's right hand there, and it took more than two months for her to retrieve it afterwards.

Originally, Qu Ping had also considered the possibility of the murderer escaping through other channels, but because the wind house was locked, he did not investigate here. How did she know that Li Dan had already obtained the key to the wind room a few months ago.

Regarding Gao Tian's case, it was enough for Zhao Yu to feel incredible, but when he looked at the second victim, Yuan Lili, he was even more surprised!
