Chapter 1729 Who Said There Are No Traces?

"Leader," a police officer from Zhangze City said to Zhao Yu after everyone came to the well, "We have already searched for the missing persons in the nearby villages and towns!

"We feel that since the corpse appears here, the murderer and the victim are likely to be people from nearby villages and towns!"

After hearing that, Zhao Yu didn't answer, but stared intently at the well that appeared halfway up the mountain.

The water wells are indeed made of bricks and cement, which looks very rough. There is a bit more cement spread along the well, but it is not particularly uniform. The bricks have been exposed in many places, which is very perfunctory.

"What's the origin of this well?" Miao Ying asked, "Does no one know?"

"No," the local police officer replied, "I asked everyone in the forest farm, and they all said they never paid attention to it."

"This well..." Zhang Yaohui said, "It looks like it was built in the 1980s and 1990s. The red bricks look very familiar. My hometown uses this kind of red bricks."

"Yes..." a guide said in the local dialect, "We also use it to build houses now! But... if we need to dig wells in the forest, we usually use stones, and we use local materials!"

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

"Yes," the guide replied, "you can see that there are stone wells in the mountains. Stones are easy to find, and they are everywhere, but bricks are hard to get!"

"That's right..." Miao Ying said behind Zhao Yu, "A lot of bricks are needed for such a deep well, and 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 again, "this well is strange. From here to the valley, there are all streams with water all the year round. If you don't live for a long time, there is no 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, he turned his head and looked into the well.

"Leader, be careful," a police officer reminded, "Because of the excavation of the body, the well has already been dug to the end, and it is more than five meters deep! Be careful!"

Zhao Yu looked down, but saw the pitch black inside, which was indeed a bit scary.

Zhang Peipei took tools, and hastily turned on a high-power flashlight to shine down the well.

At a distance of 5.5 meters, nothing can be seen on the flat ground, but it is still not too shallow in the deep and downward deep well!

If a person falls from a high place to the bottom of a well, even if he does not die, he will have to do something good or bad.

"Already... have you dug to the end?" Zhao Yu looked at the bottom of the well, then at the large amount of earth and rocks dug out beside it, and asked the local policeman.

"Yes, we have already dug to the bottom," the local policeman replied, "If you go further down, there will be no wells, and the soil quality will change significantly, making it harder.

"We dug a few more times, but no more bones were found, so we stopped."

"Besides," another local police officer added, "I don't dare to dig down to the bottom. The well is squeezed out of shape, and I'm afraid it will collapse!"

"Oh..." Zhao Yu nodded thoughtfully.

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

The radar Zhang Peipei mentioned was the electronic pulse radar specially used by the police to find bones, which had been used in the video homicide case before.

"No need for now," Zhao Yu said, "Let's wait until the identity of the deceased is revealed!"

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

"Okay..." Zhao Yu stared at the bottom of the well, still thinking about something.

"I saw it said in the report," Miao Ying asked the local police again,

"The mouth of the well was sealed with a big rock?"

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

"Have you got any fingerprints on the stone?" Miao Ying asked hastily.

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

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

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

"Okay then," Miao Ying said, "inform them and ask them to come to Qinshan Police Station tomorrow, we need to consult the situation."

"yes!"

After all, Miao Ying was the commissioner of the Criminal Department, so the local criminal police naturally did not dare to be negligent.

"Have you searched the area...?" Zhao Yu finally left the well and asked the local policeman.

"We have searched. After the incident, we have searched the entire mountain," the local policeman replied, "but nothing was found! All the footprints we found belonged to that scientific expedition team!"

"Team leader," Zhang Peipei reminded, "the last body was buried three years ago. If the murderer never came back during this period, there should be no more traces of him!"

When Forensic Zhang said this, everyone nodded.

Three years is such a long time, it is indeed enough to destroy any traces.

However, Zhao Yu smiled slightly, shook his head mysteriously and said, "No, that's not necessarily the case! I can see that, you definitely haven't done heavy physical work!"

"Huh?" When Zhao Yu said this, everyone was confused.

"Children of poor people have long been home," Zhao Yu walked up to two dark-skinned local guides, patted their shoulders lightly, and said, "When I was 8 years old, I built a house with my parents. How about you?"

"Us?" A guide thought for a while and said, "I only worked with my parents when I was in junior high school."

"I didn't..." Another shook his head.

"Hehe...it doesn't matter...I didn't mean to ask you if you have done any work, but..." Zhao Yu walked back to the well and said to Zhang Peipei, "Forensic Doctor Zhang, next, I will send someone to clean up the well. Take it down!"

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

"At that time, I need you to personally direct the entire process of dismantling the well!" Zhao Yu put away his smile and said seriously, "You need to take your people to carefully inspect every brick, and remove the bricks and cement. Fingerprints, one can be extracted for me without touching the ground, is that okay?"

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

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

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

"Understood," Zhang Yaohui said with a sense of enlightenment, "If you find the person who built this well, the case will be easy to handle?"

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