In ancient warfare, cutting off ears was the basis for determining military merits, just like beheading and nose gouging.

But Weng Tao's left ear was neatly cut off, what is the purpose of the suspect?

Does this mean that killing Weng Tao has become a merit of this person, and that ear has become his basis? Or is it a collection of commemorations?

"Team Shao, this is the note left by the suspect. Zhang Hui said as he put on gloves and took the piece of kraft paper stained with a little dirt from the hands of the people on the scene.

Shao Yong put on gloves and took the unfolding, Xiao Ran and the others all surrounded them, and the handwriting on the kraft paper was clear and chic.

As the saying goes, words are like people, from the ups and downs of the strokes, you can see the decisiveness in the writer's character, Xiao Ran can even feel the joy and full of sacredness when the suspect writes these words.

There are not many words on the vellum, and you can read them at a glance: Hello, Ah sr. His name is Weng Tao, and he is the murderer of a serial murder case. Since you can't find this garbage, then it's up to me to sentence him to death.

Signed: Cleaner.

Shao Yong stared at the handwriting on the brown paper with a deep face, without saying a word, and the surrounding atmosphere seemed to freeze for a while, extremely quiet.

Turning his hand and handing the paper back to the technician to put it in the physical evidence bag, Shao Yong looked around the scene of the corpse dumping again, and suddenly sneered: "It's ridiculous, this person is too naïve." ”

"That is, who does he think he is? and said that we can't solve the case, and he can't help but underestimate us. Someone next to him said angrily.

"Lao Zhang, the killing of Weng Tao is likely to be due to the fact that the group of people found before made another move. Otherwise, it would be impossible to find Weng Tao before us. Shao Yong looked at Zhang Hui and said.

"I understand, go back and leave the procedure to Thunder, and we will fully cooperate with you. Zhang Hui said shuangli.

Shao Yong smiled and said: "Let's cooperate in the investigation, after all, this case is a continuation of the 728 case, so it will still be investigated in the name of the 728 task force." ”

Zhang Hui nodded and replied, "Okay, then which step do we start with next?"

Shao Yong thought for a while, looked around and said, "What do you all think?" ”

"Although the deceased was dismembered by the suspect, the body parts of the deceased were basically put together. So we can ignore the broken corpse for a moment and treat these corpses as a whole corpse, so isn't that the same as throwing away the corpse? ”

There was a little silence around him, and Pi Zizhong took the lead in speaking: "Since it involves throwing corpses, we must first investigate from five locations, the place where the victim was last witnessed, the place where the victim and the murderer were initially contacted, the place where the murderer initially attacked, the place where the murder was killed, and the place where the deceased's body was found."

Now that the place where the body was found is known, the last place to be witnessed should be the head of Dongqian Village as mentioned by the taxi driver, after all, the task force found Dongqian Village shortly after Weng Tao came over.

Under such a strong defense, if the surrounding villagers had met with Weng Tao, they would definitely report it to the task force, but no. So I think that the taxi driver should be the last ordinary person to witness Weng Tao. Of course, it can't be too absolute, maybe Weng Tao finally appeared in other places outside of the surrounding area of Dongqian Village.

Assuming that the last sighting and the place where the body was found are known, then we should then look for the three locations of initial contact, attack, and killing. ”

Shao Yong raised his hand and motioned for Pi Zizhong to continue speaking.

Pi Zizhong wiped the sweat on his chin, and grinned: "But everyone has seen the surrounding environment of the corpse dumping site, basically no one pretends to monitor, and it has been several days since Weng Tao came to Dongqian Village, so there are variables in this, contact, attack, and killing location, it may or may not be in this vicinity."

Therefore, we first need to conduct a carpet survey of Dongqian Village and its nearby villages, including remote natural sites such as mountain forests, tea plantations, fields, and even caves in the mountains.

Of course, this is only the preparatory work we have to do in the early stage, and when the autopsy results come out, we can also delineate the search area from the time of death. If the time of the deceased's death is shorter than the time he arrived in Dongqian Village, then we can set a maximum range of activities according to this time. Of course, if it's a long time, it's more difficult. ”

"Who else has anything to add?" Shao Yong then asked.

"The results of the on-site investigation have not yet come out, and there may be some discoveries at that time. ”

He Xiaoli said, and suddenly raised her hand and pointed at Xiao Ran: "Plus road monitoring." Although there is very little monitoring on this county road, when I came just now, I noticed that there are still cameras at the main intersections at both ends, and you can turn down the monitoring on the main intersections around the periphery and give it to Xiao Ran to see, I have never seen anything more powerful than him watching the monitoring. ”

"Yes, Xiao Ran's eyes are like having radar installed, which is even better than big data search. Li Fangfang agreed.

Xiao Ran shook his head and smiled, and said, "Leave the monitoring to me." But I would like to add that I think in order to find the suspect who killed Weng Tao, we need to go through the 728809 two cases all over again, or even twice, three times. ”

"Aren't we all untraceable to these two cases? Xiao Ran, you all know it, now go over it again, isn't it still the same?" Shen Quliang said puzzled.

Facing everyone's inquiring eyes, Xiao Ran explained: "Yes. But when we investigated at that time, the victim used Li Lu and Liu Chen as references, in order to find the murderer, that is, Weng Tao.

But think about it, the suspect who murdered Weng Tao now, he was actually at the same time as us, and even before us, he determined that Weng Tao was the murderer. Then, the current murderer cleaner, during the period from Li Lu's murder to Liu Chen's murder, should also be investigating, and even observing Weng Tao in the surroundings. Therefore, during this period, the cleaner is likely to have intersected with Weng Tao.

From this, we review the first two cases, this time we are not going to deduce Weng Tao, but using Weng Tao as a reference, we deduce that the murderer cleaner this time must have been frequent at the scene of the two cases and around Weng Tao's residence. ”

"Got it! Got it. We were looking at it, and he must have been looking it up. There are so many ways to investigate, and the cleaners are likely to have been to the places we have been. ”

Zhang Hui suddenly said with a smile: "Then we will screen out some important nodes during our investigation, and use these nodes as the center to focus on looking for suspicious people in the last half month." ”

"It's a big project, and trying to find a cleaner is like looking for a needle in a haystack. Someone sighed.

"No matter how hard it is, we have to find out this cleaner, or the handful of people behind him. "Shao Yong cut the railway.

Xiao Ran looked at the people with heavy faces, and suddenly said: "Perhaps, we can also start from another direction, that may be a shortcut."
