Her study is very large. Fudi, a four bedroom, two living rooms and two bathrooms house, is a little too spacious for her to live alone, so she connected two of the rooms into a study. The pattern of the study is very simple. There are beech bookshelves as high as the ceiling near the wall. The bookshelves are neatly filled with books. In the center is a large desk and leather boss chair in the same color as the bookshelves, The desktop is very clean and tidy, except for the laptop and some commonly used stationery, without any fancy decoration, or even a photo frame, just like the model in the furniture city.

Jing SA entered this study for the first time. First, she was surprised by the amount of books she collected. After a close look, she found that all the books were in English. She couldn't even see a Chinese word. She had also been in the United States, so her English was very good. She could understand the titles of these books. Most of them were about criminal psychology, and a small part of them were reasoning novels. There was a book with a bookmark in the corner of the desk, Look at the location of the bookmark. I should have just seen half of it.

The cover of the leather on a black background is written in gilded script: narural.born.killer

Translated into Chinese is born killer.

Just looking at the title of the book, she thought it must be very boring.

Fufu pulled a whiteboard out of the gap behind the bookshelf, which was bigger than the one in the police station. She pointed to the whiteboard, "I'll go to the kitchen to cook dumplings, and you'll sort out the information."

Jing SA is a Leng, "ha?"

He took it for granted, "I'm only responsible for analysis, not for sorting out data." She also pointed to the desk drawer, "there are oil pens, you can use them freely, but I hope the words on the whiteboard don't have too many colors, the font should be correct, the content should be concise, I don't want to see nonsense!"

Jing SA didn't expect that she even had a request. Did she think it was ppt?

Good! She forbeared, who let himself ask for her.

"Don't worry, I will meet your requirements and won't let you down!"

“OK!” When she got to the door, she turned her head and asked, "what flavor do you want?"

Jing SA didn't reply angrily, "quick frozen dumplings can have any taste, whatever!"

Pang Pang steps out of the study. Sesame turns around her feet excitedly and follows her step by step into the kitchen.

Jing SA rolled up his sleeve, threw the information into his briefcase on the ground, and began to write and paste on the whiteboard.

When she finished cooking dumplings, she was still struggling in a group of materials. Her expression looked like a rookie assistant who arranged the copywriting for the university professor.

He put the bowl belonging to Jing SA on his desk, picked up some photos of the dead on the ground, and his black eyes flashed slightly.

"The ropes that bind children are different!"

Jing SA raised his head and wiped the sweat on his forehead. "Well, the forensic medicine also mentioned that the first child and the second child were bound with thick hemp rope. The preliminary judgment might be that the hemp rope was too thick and it was inconvenient to knot. The child's hands were thin and easy to break away. Later, the thinner rope was replaced... The third child used green nylon rope, We have also checked from the rope, but these ropes are too common, every family will have them, and they are not targeted at all. "

Pang Pang handed her chopsticks, indicating that she would eat while it was hot.

Jing SA holds up the bowl. Frozen dumplings are really not her dish, but at this time, she has nothing to pick on.

He leaned against his desk and took a look at the picture jingsa posted on the whiteboard.

"At the fifth child, it's a plastic self-locking bandage."

The self-locking strap is also very common in families. It is mostly used for binding wires, such as various wires behind the computer case. In order to prevent them from intertwining with each other, this kind of strap is used to bind them separately. The sharp end of the strap is put through the lock hole and pulled. Compared with the rope, it is not loose, firm and beautiful.
