Everyone has seen the relevant videos.

During the crime, the murderer sealed all the ingredients with wax.

At the scene, the murderer took it out directly from a bag and placed it on the table.

Including tablecloths, cutlery, bowls and chopsticks on the table.

Therefore, even though two days have passed, the dishes on the table still look like they have just been cooked.

"Zhao Dezhi uses a pair of bamboo chopsticks, placed on the left side of the noodle bowl."

"Only left-handed people have this habit of doing these two things."

The photos changed again.

It's a photo of Ding Suxi.

"The deceased Ding Suxi's information shows that he received a good higher education and spent half a year as an exchange student abroad during his college years."

Chen Yan switched to a photo again, which was a photo of Ding Suxi holding a knife and fork: "Look at this photo."

"Ding Suxi holds a fork in his right hand and a knife in his left hand."

"In Western food etiquette, a fork is held in the left hand and a knife is held in the right hand. Ding Suxi once lived abroad for half a year and was an exchange student living in a foreign family. So, it is impossible for her not to know the basic Western dining etiquette."

Chen Yan paused: "But, in the West, if you are a left-handed person, this kind of behavior is understandable."

"Let's all see..."

On the screen is an enlarged photo.

"This is the left hand of the deceased Ding Suxi and Zhao Dezhi. Please pay attention..."

The photo continued to enlarge: "Please pay attention to Ding Suxi's left index finger...there is an obvious callus here, which is obviously caused by holding a pen for a long time."

"Looking at Zhao Dezhi's left hand again, compared with his right hand, there are calluses on the thumb and index finger of his left hand."

"So, what is certain is that both Zhao Dezhi and Ding Suxi are left-handed."

"And the murderer perfectly reproduced this tiny detail at the doll arrangement site!"

Open the video and you will see the details of the murderer hanging the fishing line.

"Everyone looked at the point where the murderer hung the fishing line. It was very smooth, without any hesitation or point measurement."

"This shows that the murderer knew the structure of Zhao Mingwei's house very well and had even rehearsed it many times before he could do it so smoothly."

Who would know the Zhao family and their space layout so well?
