Rebirth of the open female forensic doctor

Chapter 277 Technical Analysis

The officers from the Lushi Police Station who came to work in the morning watched curiously as a little girl walked into the police station early in the morning, and walked towards the office of the criminal investigation team familiarly.

When Ye Fan entered the office of the criminal investigation team, the criminal detectives who had already come to work were stunned for a moment. After realizing it, they all looked at her with strange eyes. up.

Although the little girl is young, she is highly valued by Feng Lao, so she directly joined Miss Project as an assistant, which is amazing.

Naturally, some people don't like it. After all, they are regular criminal police officers who are not qualified to join the special case team. She has not even grown a hair yet. She is a little girl who just went to college, why not.

It's just that they didn't dare to make trouble, because the regular team came.

"Ye Fan, come here so early?" Chang Dui hurried out of the office when he heard that Ye Fan was coming. It's not easy.

"Ye Fan." He Pingfei and Han Han greeted her happily when they saw her. The smiles on their faces were very sincere, as if they were seeing their own little sister, rather than pretending to take care of Feng Lao's face. The effort also made other police officers deeply aware of the status of this little girl in the task force.

"Chang Dui, Brother He, Sister Han." Ye Fan greeted them one by one.

"Go, go to the meeting room first, Su Liang and Xia Dong will be there later." Chang Dui said to Ye Fan with a smile.

"Well, good." Ye Fan followed the regular team and walked towards the conference room, with He Pingfei and Han Han clustered around her.

In the conference room, Su Liang and the others hadn't arrived yet. Team Chang said that they worked overtime last night and were still sorting out the materials. They probably had to wait a while, so they first asked Ye Fan if he was used to it at school.

Ye Fan has answered many times in the past two days, and answered it again. She can feel everyone's sincere concern, and a warm breath lingers in her heart.

After waiting for more than 20 minutes, Xia Dong, Su Liang and Qian Qian hurried over with a few documents. As soon as they came in, they first smiled and asked Ye Fan a few words of concern, and after a few words, they began to analyze the case meeting.

As for Liu Mang, he knew that there was going to be an analysis meeting today, but by this time, he hadn't come to work, and no one had mentioned him, so it would be better if he didn't come.

Everyone sat down according to the positions they had that day. This time, there were no notebooks in front of them. Qian Qian put the documents they had just sorted out one by one in front of everyone.

Today, this analysis meeting is a special session for the technical group, so Su Liang will host it.

Although he is a dull gourd, his eyes will light up when talking about technical testing.

Su Liang pressed the projection pen, and a photo appeared on the projection cloth, which was the black plastic bag used to hold the corpse.

"As expected, no fingerprints can be covered on the black plastic bag, because it has been wet by rain, and no useful information can be detected."

As Su Liang said, everyone listened, looked at the documents in their hands, and continued to listen to him: "However, we detected the blood DNA of the deceased in the bag, and we can confirm that this black plastic bag is for In addition to the headless female corpse, we also detected another ingredient."

As Su Liang said, he smiled slightly at Ye Fan and said, "Ye Fan, thanks to your reminder, this black plastic bag is not brand new."

Ye Fan's eyes lit up, and under everyone's admiring eyes, he smiled embarrassedly.

Su Liang continued: "We detected residual components such as metal, humus, and muck in the plastic bag. These components can prove that the black plastic bag was used to store other things before it was used to store the corpse."

"It's garbage." Xia Dong heard where these leftovers came from.

"That's right." Su Liang affirmed his statement.

"So, the murderer took out the garbage in the plastic bag and took the corpse in the plastic bag." Chang Dui nodded, looked at Ye Fan, and said with unconcealed admiration in his eyes: "Your deduction It seems that everything is correct, the black plastic bag was randomly taken by the murderer in a panic, and it is a garbage bag in a public area, and the garbage of ordinary households does not have such complicated ingredients."

Ye Fan was embarrassed again, she looked at the document and asked; "From the composition of the garbage, can I infer what kind of public area it probably came from?"

Su Liang: "Most of them are domestic waste. At least construction sites and commercial centers can be excluded. I prefer residential areas, places where people live like schools."

It is easier to handle if it is directional, which is a good clue.

Ye Fan was slightly happy, and wrote this down.

Su Liang continued to tap the projection pen, and another photo was changed on the projection cloth, which was the photo of the small brown stain that Ye Fan cut out from the corpse's clothes.

"There is also this small stain. After our technical inspection, we found pigment powder, linseed oil in dry vegetable oil, vehicle and plasticizer..." Su Liang said. Ye Fan was a little confused when he piled up professional terms.

Her existing knowledge is all learned from books with her super memory, but she is not a god, it is impossible to read all the books in just a few months, especially some technical things , cannot be learned by memorization alone.

Su Liang saw that she was puzzled, and after talking about the detected ingredients, he made a simple and clear summary: "General pigments are composed of these ingredients."

Ye Fan nodded clearly, looked at the relevant test report in the document, and kept it in his heart.

"Pigment? According to Ye Fan's initial autopsy, the headless female corpse was lying on her back when she died, and the place where the stain was stained is here..." Chang Dui pointed to the position where his left shoulder was lowered back, thinking: "In what kind of environment, under what kind of situation, would you get the paint in that posture?"

Everyone touched the same spot subconsciously, imagining what it would be like.

"In terms of paint, could it be those freshly painted murals or something? The murderer pressed the dead on it..." Han Han first speculated, before she finished speaking, she shook her head and said: "No .”

"It's really wrong." Qian Qian continued: "If the murderer pressed the deceased on the colorful wall painting, it shouldn't just be stained on that small piece, and the whole piece on the back should be stained, and the deceased When he was killed, he was lying on his back instead of standing, which can be proved by the analysis of the blood splatter on the skirt of the deceased."

Su Liang released the screenshot of the blood splatter on the skirt that Lu Junyu focused on at that time, clicked again, and played a short video of the blood splatter trajectory simulated by computer technology.
