The police officers who came to work in the morning of the Lu City Police Station 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 with familiarity.

When Ye Fan entered the office of the criminal investigation team, the criminal investigation police who had already come to work were stunned for a moment, and after reacting, they all looked at her with strange eyes, and several police officers who had a case of a female corpse in the wilderness greeted her warmly.

Don't look at people, the little girl is young, but she is deeply valued by the old man, and she directly joins the project lady as an assistant, which is awesome.

Naturally, some people can't get used to it, after all, they are regular criminal policemen who are not qualified to join the task force, she hasn't even grown her hair yet, a little girl who has just gone to college, why.

It's just that they don't dare to make trouble, because the constant team is coming.

"Ye Fan, come over so early?" As soon as the Chang team heard that Ye Fan was coming, he hurriedly walked out of the office, he walked quickly, and he always had a smile on his face, but he scared the criminal investigation police under him a lot.

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

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

"Let's go, let's go to the conference room first, Su Liang and Xia Dong will be there later. Team Chang said to Ye Fan with a smile.

"Well, good. Ye Fan walked towards the conference room with the regular team, and He Pingfei and Han Han hugged her left and right.

In the conference room, Su Liang and the others had not yet arrived, and the Chang team said that they worked overtime last night and were still sorting out the information, and it was estimated that they would wait for a while, so they first asked Ye Fan with concern if he was used to it at school.

Ye Fan has answered many times in the past two days, and she has answered 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 hurriedly came with a few documents, and as soon as they came in, they first smiled at Ye Fan and asked a few questions, and only after saying a few words did they start the case analysis meeting.

As for Liu Mang, he knew that he was going to have an analysis meeting today, but at this time, he hadn't come to work yet, and he hadn't mentioned him, so it would be better not to come.

Everyone sat down according to the position of that day, this time there was no notebook in front of them, Qian Qian put the documents they had just sorted out in front of everyone one by one.

Today, this analysis meeting is a special session of the technical group, so it is presided over by Su Liang.

Although he is a stuffy gourd, his eyes will light up when he analyzes the topic of technical testing.

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

"As expected, the black plastic bag did not have any fingerprints on it, because it was wet from the rain, and no useful information could be detected. ”

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

Su Liang said, chuckling 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 appreciative gaze, he smiled embarrassedly.

Su Liang continued: "We have detected the remnants of metal, humus, muck, etc. inside the plastic bag, which can confirm that the black plastic bag was filled with other things before it was used to hold the corpse. ”

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

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

"In this way, the murderer took out the garbage in the plastic bag and held the body in the plastic bag. Team Chang nodded, looked at Ye Fan, and said with unconcealed admiration in his eyes: "Your inference seems to be correct, the black plastic bag was taken by the murderer in a panic, and it is a garbage bag in a public area, and the garbage of ordinary families does not have such a complex composition." ”

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

Su Liang: "Most of them are domestic waste, at least we can exclude places such as construction sites and commercial centers, and I prefer residential areas and schools where people live." ”

It's easier to have a direction, and that's a good clue.

Ye Fan was slightly happy in his heart and wrote this down.

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

"There is also this small stain, after our technical inspection, from this stain detected pigment powder, linseed oil in dry vegetable oil, color carrier agent and plasticizer......" Su Liang said a bunch of professional terms, Ye Fan heard a little confused.

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

Su Liang saw her puzzlement, and after finishing the detected ingredients, she summarized simply and clearly: "Generally, pigments are made up of these ingredients. ”

Ye Fan nodded clearly, looked at the relevant test reports in the document, and memorized them attentively.

According to Ye Fan's initial autopsy, the headless female corpse was lying on her back when she died, and the stained position was here...... "Chang Team pointed to the position where his left shoulder was lowered back, and pondered: "In what kind of environment, under what circumstances, will it be stained with paint in that posture?"

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

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

"It's really not right. Qian Qian continued: "If the murderer pressed the deceased on the painted wall painting, it should not just be a small piece of the position, and the whole piece on the back will be contaminated, and the deceased was lying on his back when he was killed, not standing, which can be corroborated from the analysis of the blood splatters on the deceased's skirt." ”

Su Liang released the screenshot of the bloodstained footage of the skirt that Lu Junyu focused on shooting at that time, clicked it again, and played a short bloodstain splash trajectory simulated by computer technology.
