In the conference room, Lao Liu was reporting the autopsy results.

"The deceased female, aged between twenty-nine and thirty, one meter tall ****, weighed fifty-one kilograms, had sex before death, and the time of death was about eight o'clock and nine o'clock last night, because her face had been completely chopped, her original appearance could no longer be seen."

"Like the previous five victims, they were all killed after being ***. It is initially speculated that the killer suffocated the victim after the violence, and then used a knife such as a kitchen knife to slash the face of the deceased before burying him. ”

"The body fluids in the body of the deceased are also completely consistent with the previous ones, and it can be presumed that the same murderer committed the crime!" After that, Lao Liu nodded at Chen Li.

Qiao Yifan closed his eyes and did not answer.

"That's what happened on the ground." Chen Li took over the conversation: "The location of the buried body belongs to the green belt, because the needs of management often replace some seasonal vegetation for holidays, so the soil there is relatively loose, and there is no trace of the murderer's tools." ”

"The scene of the crime was not the first scene, the first scene was in a small forest more than 100 meters away from the scene of the crime. After the murderer committed violence there, he removed the body. The body was buried shallowly, covered with only a thin layer of turf. So, when the students were rinsing, the turf was lifted by the water. ”

"In addition, not far from the burial site, some plastic film and dozens of bamboo pieces were also found, after inspection, the soil they were stained with was indeed the scene, but there was no residue related to the corpse, and later after inquiry, it was found that it was a common thing for green workers, considering that it would be used in the future, so they did not take it away after use."

"Has the identity of the deceased been clarified?" Qiao Yifan asked.

"No identity has been found on the body of the deceased, and his identity cannot be determined for the time being, but relevant notices have been issued."

"Tell me what you think." Qiao Yifan still didn't open his eyes.

"The location of the crime is relatively remote, and unlike the nearby hiking trail, which is for vehicles, it leads to the villa area by the sea. Except for the owners of the villa area, there are basically no other cars coming in and out there, so there are not many cars taking that road, and even fewer people. Lao Liu said slowly. My question is, what is a young woman, alone, running there at eight or nine o'clock in the evening? ”

"Count one." Qiao Yifan said.

"In addition to Lao Liu's, I have two questions." Chen Li continued: "First of all, the first scene is actually more hidden than the burial site, why did the murderer drag the body to the greenery on the side of the road to hide the body? Isn't he afraid of being bumped into by other people passing by? Moreover, since it is a corpse, of course, the more concealed the better, and the green workers in this place will often go, isn't it very contradictory? ”

"As you said, the soil is loose and the killer doesn't have the tools." Lao Liu said with a smile.

"Unless the murderer expects that no one will show up during the process of burying his body, otherwise, the risk is too great!" Chen Li frowned and continued: "Moreover, Xiao Ling and the others didn't just pass from there!" ”

"The second one!" Qiao Yifan said in a deep voice.

"Secondly, I carefully checked at the scene, and found no spilled soil within 100 meters of the burial site, and after the body was dug up, the soil used for burial next to it could not even fill half a small pit! So, where did all the dirt that the murderer dug up go? ”

After listening to Chen Li's report, Qiao Yifan was silent for a long time, and then suddenly said: "Let's go, go to the scene again!" ”

…………

At the edge of the burial pit, Qiao Yifan took matters into his own hands and continued to lift the soil in the pit out, and after a few minutes, he finally stopped and squatted down, gently brushing away some of the dirt with his gloved hands.

"If the killer doesn't have the tools, then how did this come about?" Qiao Yifan pointed to a not very obvious trace in the pit. "It's clearly the mark of a hoe."

"Lao Liu, collect evidence and do trace identification!" Qiao Yifan stood up.

"But it still doesn't make sense, could it be that the murderer still carries a hoe to commit the crime?" Chen Li frowned. "And where did the rest of the dirt go?"

"Where are the films and bamboo chips you mentioned?" Qiao Yifan didn't answer and asked again.

"Because I didn't think it was necessary, I didn't move over there." Chen Li pointed to a corner of the green belt not far away.

Qiao Yifan immediately walked over and began to carefully study the things on the ground.

Films are ordinary insulating films that are usually used to protect freshly planted seeds. And now, it has been crumpled and thrown there. Next to it are twenty or thirty finger-wide pieces of bamboo, about 60 centimeters long, which are supposed to be used to temporarily protect the newly planted green plants.

After looking at it for a while, Qiao Yifan immediately brought both of these things to the side of the burial pit.

Chen Li asked confusedly, "Boss, what are you doing here?" ”

Qiao Yifan ignored it and began to put the bamboo pieces on the pit surface one by one, and the length of the bamboo slices was just enough to fit on the edge of the pit on both sides.

After a while, Qiao Yifan arranged all the bamboo pieces very evenly, and when he looked at it again, these bamboo pieces that had been placed were just covering the pit surface. Then he unfolded the film, folded it into a shape about the size of the pit, and spread it on top of the bamboo pieces.

"I'll you!" Chen Li touched the back of his head and suddenly realized.

"Boss, this time I'm really convinced!" Lao Liu also praised.

Qiao Yifan stood up again and said in a deep voice: "This is a premeditated murder!" ”

"You mean, someone dug a pit here beforehand and waited for the dead to come? And that would explain where the dirt goes! Chen Li said.

Qiao Yifan nodded and said slowly: "Since the pit has been dug in advance, if you don't deal with the dirt, of course, it will be easy to be discovered." ”

"In other words, the murderer had already planned to dig a pit here and then get the dirt somewhere else, and he must have used a very special method to keep the dirt from being scattered everywhere." Lao Liu added.

"Well, this also explains why the murderer didn't use the tools at the time!" Chen Li also nodded.

"Chen Li, hurry up and investigate the villa area to see if there are any missing people and find out the relatives and friends of these people!" Qiao Yifan's cheeks puffed out and took a deep breath.

"Good!" Chen Li immediately took out the phone.

"Boss, could it be that the deceased is the owner of the villa area?" Lao Liu was puzzled. "Whoever lives there isn't a rich man, they probably won't walk home, right?"

"At the very least, the deceased had a connection with someone in the villa area, otherwise, she wouldn't have come here in the middle of the night!" Qiao Yifan sighed: "Moreover, she should come often, otherwise the murderer's premeditated plan will lose its meaning!" ”

"It makes sense, and only this reason makes sense!" Lao Liu's brows finally stretched.

Qiao Yifan didn't say anything again, because he was thinking about another question in his heart: since it was murder, this case should be completely different from the previous five. But why is the approach exactly the same?

Qiao Yifan fell into deep thought.
