"I'm here to do the investigation, not to collect evidence!" Zhao Yu said nothing, "Where can I wear gloves? Don't worry, your daughter is not Sherlock Holmes, you can't tell!"

After saying that, he reached out to grab a book despite the old man's objection.

It was a book about anesthesiology. Zhao Yu looked through a few pages and found that he still remembered many notes in the book.

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

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

"No, no!" the old man replied affirmatively, "She only worked in a pet clinic many years ago. She was the famous Dr. Lu veterinary shop. Dandan worked as an assistant for them! Maybe she had to learn some knowledge in this area, right?"

What!?

Pet clinic?

Veterinary shop?

Zhao Yu was surprised. The anesthetic used by the murderer in the shopping case was an animal drug, and the source of this drug happened to be a veterinary store!

This will not be a coincidence again, right?

Could it be that Li Dan...

Zhao Yu put down the book and scanned the whole room again. For some reason, he always felt that maybe he could find something more important in this room.

"Old lady!" Zhao Yu thought for a while and asked, "Have you surfed the Internet at home?"

"It's here!" the old man replied, "I'm useless, but my daughter is useful!"

"Where is a computer? Is there any?"

"My daughter has a laptop, which she often carries with her, so she shouldn't be here."

"Then..." Zhao Yu pointed to the room and said, "She has no desk in the room. How do she play with the computer? Are she lying on the bed?"

"Yes, it's just lying on the bed to play!" said the old man without reservation, "not only playing with computers, but my daughter also lies on the bed to write. Oh... By the way, there are many white paper under her mattress. I often see her writing on it, and there are many photos!"

oh!

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

"What!? What did you say? Under the mattress?" Zhao Yu was shocked and asked with wide eyes wide open, "What is written on it...?"

"I...I don't know either! I just accidentally 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 just saw it through the crack of the door!" The old man was so scared that he was incoherent and didn't know what to say.

ah!?

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

"Police officer!" The old man was frightened and rushed over to stop Zhao Yu, "My daughter has a cleanliness, and this sheet... can't move! My daughter's eyes are very poisonous. No matter how she cleans up, she will definitely see it!"

"Old lady!" Zhao Yu shouted excitedly, "When is it now? Are you still thinking about your daughter's obsession with cleanliness! I tell you, the things your daughter wrote may be those things that can kill her life, you... are you still stopping me?"

Seeing Zhao Yu so excited, the old man realized that the matter was of great importance. Finally, he reluctantly let go of Zhao Yu's arm and honestly retreated.

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

After pulling it open, a scene that appeared on the bed board made Zhao Yu feel shocked!

But the flat bed board was indeed covered with white paper sticking together. The white paper was densely filled with many words, including many photos, pictures, and copies or printed documents!

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

Grandma, a bear!!

At that moment, Zhao Yu was thriving in his heart and his bloodline was bleak. He didn't have to look at the words carefully. Just based on the photos on the white paper, he could have been completely and truly sure that the heroine Li Dan was the one who bought a shopping case - the real murderer!!!

But seeing the photos of Gao Tian, ​​Yuan Lili, Luo Meina and others were all pasted in conspicuous positions, and all their information was recorded with a black pen next to them. It was obvious that Li Dan had conducted a very detailed investigation of them.

Zhao Yu rolled the mattress aside and looked carefully at the beginning of the white paper. But below the sweet photo, there was a black and white photo printed with a printer. The photo showed a ventilation port of a ventilation duct.

Looking at the bottom, the date, location and other information are marked in detail, which are exactly consistent with Gao Tian’s shopping situation.

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

Ah Xi!

Zhao Yu collected this information and could actually connect the process of the shopping case. When he finally understood the method of committing the crime Li Dan used, he couldn't help but be deeply shocked again!

Li Dan’s plan was so meticulous that it was incredibly meticulous that it was perfect! Before she decided to attack Gao Tian and others, she even made careful preparations several months in advance.

Take Gao Tian as an example. Li Dan knew that Gao Tian was coming to Qinshan to listen to the concert in the morning and knew her seat number.

She even knew that after the concert, Gao Tian would definitely walk through the underground passage, and there was no camera in the underground passage.

Since the sweet seats are in front, they will naturally be behind the crowd when leaving, which will give Li Dan a better chance to get off the phone.

Zhao Yu estimated that Li Dan should have bought tickets and entered the venue, and then followed Gao Tian.

When the concert ended and Gao Tian entered the passage, Li Dan fainted while others were not paying attention, and then dragged her to the power distribution hut in the passage where no one paid attention, and from there he performed anesthesia and shopping!

The most amazing moment came. After committing the crime, Li Dan did not rush to escape, but came to the wind room on the other side of the passage.

The wind room is a place to provide air supply to the underground facilities of the gymnasium, where several ventilation ducts lead to other places. Li Dan waited until dawn before entering the ventilation duct, and then left the exit of the gymnasium sanitation department according to the pre-planned route.

When she left, it was just when the sanitation workers were at work. She had already prepared a dress for sanitation workers and left the gymnasium while there were too many people. Later, no matter how powerful the police officers in charge of checking the surveillance videos were, they would never notice it.

What's even more amazing is that in order not to make the surveillance video suspicious, she actually prepared a container containing formalin in the ventilation duct early in the morning and hid Gao Tian's right hand there. It took her back more than two months later.

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