"Leader," a police officer from Zhangze City said to Zhao Yu when everyone came to the well, "We are already looking for missing people in the nearby villages and towns who echo the characteristics!"

"We feel that since the body is here, it is very likely that the murderer and the victim are from nearby villages and towns!"

After hearing this, Zhao Yu did not answer, but stared intently at the well that appeared halfway up the mountain.

It is true that the wells are made of bricks and cement, which looks particularly rough, and the cement along the well is still a little more, but it is not particularly uniform, and the bricks have been exposed in many places, which is particularly perfunctory.

"What the hell is the origin of this well?" Miao Ying asked, "and no one knows?"

"No," replied the local officer, "I asked everyone in the forest farm, and they said they never noticed." ”

"This well ......," Zhang Yaohui said, "looks like it was built in the eighties and nineties of the last century, and the kind of red bricks look very familiar, and my hometown uses this kind of red bricks." ”

"Yes...... "yes," said one of the guides, speaking in the local dialect, "we use it to build houses now!" but ...... If we need to dig a well in the forest, we usually use stones and use local materials!"

"Stones?" Zhao Yu asked, "Stone Well?"

"Yes," replied the guide, "you can see, the mountains are full of stone wells, and stones are easy to find, and they are everywhere, but bricks are hard to luck!"

"It's also ......" Miao Ying said behind Zhao Yu, "Such a deep well, you have to use a lot of bricks, the traffic here is inconvenient, if you want to use bricks to build the well, it must be very troublesome!"

"Yes, leader," said the local policeman, "this well is strangely coming, and from here into the ravine, there are all small streams, and there is water all year round, and if you don't live for a long time, you won't need to dig a well here!"

"The point is, isn't there no water in the well?" Zhang Yaohui sighed.

Zhao Yu still didn't respond, and looked into the well.

"Leader, be careful," a police officer reminded, "because of the exhumation of the corpse, the well has been dug to the end, more than five meters deep!

Zhao Yu looked down, but saw that it was dark inside, which was indeed a little scary.

Zhang Peipei, with tools, hurriedly turned on a high-power flashlight and shone it downhole.

At a distance of 5.5 meters, you can't see much on flat ground, but it still doesn't look shallow in a deep well!

If a person falls from a high place to the bottom of a well, even if he can't die, he has to fall out of the way.

"Already...... Have you dug the end?" Zhao Yu looked at the bottom of the well, and then at the large amount of dirt and stones dug up next to it, and asked the local police.

"Yes, we have already dug to the end," replied the local officer, "and further down, there will be no wells, and the soil will change significantly and become harder."

"We dug a few more times, but we didn't find any more bones, so we stopped. ”

"And," added another local officer, "I don't dare to dig underneath, the well is a little deformed, and I'm afraid it will collapse!"

"Oh......" Zhao Yu nodded, thoughtful.

"Team leader," Zhang Peipei said, "Do you want to bring the radar over to detect it?"

The radar Zhang Peipei is talking about is an electronic pulse radar used by the police to find the bones, which has been used in video homicide cases before.

"Don't use it for the time being," Zhao Yu said, "Let's wait for the identity of the deceased to come out first!"

"Well, but ......," Zhang Peipei said again, "I have seen Section Chief Wang's laboratory analysis, and there is a clear difference between the soil at the bottom of the well and the soil where the body is buried, and there should be nothing underneath!"

"Good ......" Zhao Yu stared at the bottom of the well with good eyes, still thinking about something attentively.

"I saw that the report said," Miao Ying asked the local police officer, "that the mouth of the well was sealed with a big stone?"

"Yes. The local police officer hurriedly signaled, and everyone saw a rectangular rock.

"Have any fingerprints been extracted from the stone?" Miao Ying asked busily.

"No," replied the other party, "only eyewitnesses were extracted." At that time, a scientific expedition team camped here to see if there was water in the well, so they pushed away the stones and dug them briefly, but they found the bones!"

"The scientific expedition team?" Miao Ying asked again, "Where is the scientific expedition team?"

"Northwest Agricultural University," replied the other party, "a professor who studies biology leads a group of students! They were supposed to stay here for a week, but it's good that it's over early." ”

"Okay," Miao Ying said, "inform them and let them come to the Qinshan Police Station tomorrow, and we will inquire about the situation." ”

"Yes!"

After all, Miao Ying is the commissioner of the Criminal Department, and the local criminal police naturally dare not be slack.

"This is around here...... Have you searched for everything?" Zhao Yu finally left the well and asked the local police.

"After the incident, we have searched the entire mountain," the local police officer replied, "but nothing has been found!

"Team leader," Zhang Peipei reminded, "the last body was buried three years ago, and if the murderer never came back during this period, there should be no trace of him again!"

When Forensic Doctor Zhang said this, everyone nodded.

Three years is a long time, enough to destroy any trace.

However, Zhao Yu smiled slightly, shook his head mysteriously and said, "No, this is not necessarily! I can see that you must not have done heavy physical work!"

"Huh?" Zhao Yu said, and everyone was confused.

"The children of the poor are in charge of the house," Zhao Yu walked up to the two dark-skinned local guides, patted them lightly on the shoulder, and said, "When I was 8 years old, I followed my parents to build a house, what about you?"

"We?" said one of the guides, after a moment's thought, "I was in junior high school before I worked with my parents. ”

"I didn't ......," the other shook his head.

"Huh...... Never mind...... I don't mean to ask you if you've ever worked, it's just ......" Zhao Yu walked back to the well and said to Zhang Peipei, "Forensic Doctor Zhang, next, I will send someone to demolish this well!"

"Oh?" Zhao Yu's words were always unexpected, making everyone unable to keep up with their train of thought.

"At that time, I need you to personally direct the entire demolition process of the well!" Zhao Yu put away his smile and said seriously, "You need to take your people to carefully inspect each brick, and extract the fingerprints on the bricks and cement for me without landing on the ground, is it okay?"

"Oh......" Zhang Peipei finally realized, "you mean, to find out who built this well?"

"Carrying bricks and mixing cement, whether it is building a wall or a well, the principle is the same!" Zhao Yu gestured with a gesture of plastering cement, "The fingerprint will be sealed in the cement intact, that is, a ready-made fingerprint mold!"

"So, no matter how many years it takes, the traces will be there!"

"Understood," Zhang Yaohui said with understanding, "if we find the person who built this well, the case will be easy to handle?"

"Not only that," Miao Ying said, "this well is obviously specially used to bury people! Therefore, the person who built this well is very likely to be the murderer in this case, !!."
