The other two were not forensic examiners, but were collecting trace evidence, which in modern times is also called trace examination and technical investigation.
This was because Song Ming was aware of his responsibilities. He carried out forensic work, conducted forensic research, provided professional assistance to the operations department, etc. He proposed to the operation team that more professional people could be responsible for the traces.
During the discussion at the meeting, Lin Mo naturally agreed, and based on the trace inspection and technical investigation of later generations, he improved his suggestions and set up corresponding departments in the action team, but they were not called trace inspection and technical investigation.
At present, they basically work under the name of the logistics department of the action group. Although they are not subordinate to each other, because Song Ming was the first to make suggestions, they also take it as the main one and coordinate their work.
Zhang Hongxin, who is in charge of logistics, has basically delegated power. He doesn't know much about these things, and the three are related, so it's better to let professionals like them do their own work.
Lin Mo and others drove out of the city, changed their clothes, bought some things, rented a large awning, loaded the belongings brought by Song Ming and others onto the boat, and then drove along the Qinhuai River.
Kuangjia is located in the countryside of Yuhuatai in the south of the city. It should be regarded as a rural area on the outskirts of the city! It is not connected to the city, but not far from the city. It is a small village where dozens of families live together.
However, they did not rush there immediately, but went up the Qinhuai River to see where the case occurred.
To be honest, this section of the Qinhuai River close to Nanjing has been a prosperous place since ancient times. It is an extremely prosperous waterway in Nanjing. Now, the boats are crowded with each other. Even at night, it is unreasonable to accidentally drown people.
The place where Kuang Dacheng's body was found was not far from the mouth of the river. The wheel on which the body was hung was similar to a paddle wheel, except that it was mounted on the stern of an old wooden boat and relied on human power to paddle through the water.
It was only invented in the early Republic of China, but it quickly became popular in various places. It is mainly used to carry passengers on short-distance ferries across rivers.
Lin Mo, Song Ming and others were sitting on the bow of the boat, seemingly looking around, but in fact they were quickly observing the surrounding situation, while the awning slowly sailed upstream along the river.
"You three, after looking around this circle, have you noticed anything?" After walking for one kilometer, Lin Mo spoke.
The other two wanted to say it, but were stopped by Song Ming. Song Ming smiled and said: "Why did Captain Lin ask questions knowingly? Didn't you see it too?"
Lin Mo smiled and said: "These are all professionals. I still need you to give a professional analysis from a professional perspective."
Song Ming nodded and didn't rush to talk anymore. This was not his professional scope. He opened his mouth just to see Lin Mo's attitude towards them. He had been recruited for a while, but the work had never started. He said that he didn't feel a little uneasy.
That's nonsense.
A person next to him said: "The current flow of the Qinhuai River is gentle, and even the water of the Yangtze River has a hint of backflow. If the hydrology does not change recently, this should be the reason why the body can be hooked, otherwise it will definitely be involved.
In the river, it completely disappeared.
In addition, the water is gentle and there are few eddies around it, so it is difficult to drown people in the water, and it is also difficult to wash the body to the other side of the river bank. The body is located on the side of the river, that is, the west bank.
It can be preliminarily concluded that the victim had an accident on the west bank of the Qinhuai River, or to be more precise, he entered the water near the west bank, and the boat approached the shore at night. Based on this, it is inferred that the victim entered the water from near the shore or on the shore."
After he finished speaking, the other person glanced at Lin Mo and Song Ming, said nothing, then took over the conversation and continued to speak.
"There are residential houses on both sides of the strait, and there are many brothels and opium dens in Yanliu. In addition, there are boats parked along the coast. Even late at night, both sides of the strait are by no means a quiet and uninhabited place.
Even if no one is seen for a while, for the person who committed the crime, this is definitely not the first choice place to commit the crime or dump the body. The environment along the coast is relatively wide, and based on the water flow and the time when the victim was most visible, it is unlikely to be upstream.
Abandon corpse.
Moreover, this does not include boats and other obstacles along the way that blocked the slow movement of the corpse. Therefore, the victim probably entered the water at a fork, tributary channel, etc. on the west bank of the river, and was then taken into the Qinhuai River.
On the west bank of the Qinhuai River, which is relatively close to the Yangtze River, river forks, tributary waterways, etc., hardly have much water supply, the flow rate is extremely slow, and many of them are even stagnant water, and not many bodies can be taken out.
The victim either entered the water very close to the Qinhuai River, or entered the water in a branch with a slightly stronger current, or entered the water in a water channel very close to the place where the body was found.
I prefer the last one. The flow of the Qinhuai River is indeed gentle, but there is a slight difference between the middle of the river and the two banks. The faster flow in the middle of the river will slowly roll things on both sides toward the center of the river.
Just like that, is the foam generated by the sewage poured into the river by the boat girl washing clothes slowly floating towards the middle of the river? The same goes for the corpses.
Therefore, if the body entered the Qinhuai River far away from the place of discovery and was carried by the river to the place where the body was found, the body should have floated to the center of the river and would not be caught by the ship's hook.
I just looked at it and found that there was a qualified waterway nearby when you asked. Of course, specific tests may need to be conducted. The density of pigs is similar to that of humans. You can slaughter a pig with a similar target weight to conduct a test."
Lin Mo nodded slightly, with a smile on his face, and acknowledged the analysis of several people. Lin Mo had similar views to them, but his thinking was not as detailed and professional as theirs, and some situations were based on estimates.
Seeing Lin Mo nodding in approval, the person who spoke last spoke while the iron was hot: "Captain Lin, why don't you go back and check, maybe there are some traces that can lead us to the location where the victim entered the water!
Moreover, it is not far from the Yangtze River. For safety reasons, the other party could have taken the body there and thrown it into the Yangtze River so that we would never find it again, but the other party chose such an unsafe method.
It is very likely that the other party encountered something and had no choice but to do it, and there is a high probability that he met someone who was out in the middle of the night, so I suspect there should be witnesses to the case."
Lin Mo shook his head and nodded, saying: "I agree with the latter analysis, but the former suggestion is not valid. As you said, the other party may have encountered something or someone who disposed of corpses or even living people in such a hurry.
No matter what it is! If this happens, can the other party feel at ease? There will definitely be attention. What we need is to investigate secretly and then touch the other party from behind, instead of being noticed early and running after the other party."
Several people continued to communicate in low voices. The boat may be getting farther and farther away from the crime scene, but it is getting closer and closer to the target village and is about to arrive.
The waterway can lead to the small village not far away, and there is a section that requires walking. Fortunately, Lin Mo and others have already disguised themselves, but before going ashore, everyone was always vigilant about the surrounding area.
Although it was just a small village, surrounded by acres of farmland and the like, and there was no place suitable for hiding, surveillance, and observation, people still did not dare to be careless.
Everyone gathered together, carrying incense, candles, soul sails, paper bundles and other things, and walked towards the small village, as if they were sending these funeral items for each other.
In the village, all surnames live together, there are no clans, and the jurisdiction belongs to Nanjing, which has effective management. Not to mention that there are two police officers in the village, so there is not much mess here.
Under the guidance of the villagers, everyone found the Kuang family in the sparse village, without attracting much attention. Yu Chengjie said that these were some sacrifices sent by his in-laws, and took a few people to the backyard.
"In the past few days, no strange faces have come into the village to inquire or stay nearby, right?" Lin Mo asked. This was what he had told him before leaving.
Of course, if there were any, Yu Chengjie would leave first on the grounds that there was something urgent and leave a secret note at the place where they landed, and they would not come, but Lin Mo still needed to confirm.
The small village is not connected to any waterway, and the waterway not far outside the village is only an irrigation waterway that can barely carry boats, let alone any roads. If strangers are stranded, there is a high probability that there is something wrong.
"It has been confirmed that except for the husband who performed the work and close relatives, no one else came. And these people are all known to each other, there will be no problems, and they have no suspicious behavior."
Lin Mo nodded and said nothing more, and after Yu Chengjie said a few polite words, he also took out the clothes that had been properly stored.
Song and Ming were not polite. They put on gloves, masks, hats, and white coats. They also put a white cloth on the table. Then they took the tools and evidence and inspected them carefully.
The clothes were a set of casual clothes, not the police uniform that Lin Mo thought, which made him curse the people in the police station for not recording it in detail.
This is very important. I changed into casual clothes when I was away from work. It was obvious that I was going to do some personal things, and it was not an ordinary private matter.
If they had known that he was wearing casual clothes, they would have been alert when Yu Chengjie reported the case for the first time, and there would be no need to delay it for another day.
Yesterday, although they went to check, they only followed Yu Chengjie's reminder and made a secret investigation without going in-depth. Although they obtained the situation recorded by the police station, they did not verify this.
However, Lin Mo was just annoyed. They also knew how the police station handles cases, but after returning, they had to remind everyone that they must verify all the details again when they encounter a case that the police investigated first.
Especially for cases classified as accidents by the police, they most likely have not paid much attention to them, so they must pay special attention to avoid such situations happening again.
Lin Mo was not idle either. He was fully dressed and stepped forward to watch, but he did not get started directly. For professional matters, professional people should come first to avoid damaging any traces.
Of course, his behavior was also to set an example for others. Otherwise, it would be difficult for forensics and trace examination to get the attention of other people in the team, and they would continue to be idle.
To be honest, Lin Mo has placed a lot of expectations on forensic medicine and trace examination. If it were useless, it would not be taken seriously in modern times, and it is common in the world.
In addition, their utility is not only to provide assistance for a single case, but also to collect fingerprints at crime scenes, isolate suspicious ones, and use them as evidence for future investigations.
