Detective From the Future: One hundred and fifty-three, there are many difficulties
The three teams returned to the police van.
Zheng Kaixuan sat in the second row, spread out a map of the Moon River, and ticked a circle with a pencil: "This is where we are now. It is located at the lower reaches of the Moon River. The riverbed is 100% wide. Dormy."
Han Bin looked at the map and pointed to the upper reaches of the river:
"The Moon River is more than 30 kilometers long, and the river is not a straight line. There will always be an angle of nearly 90 degrees when going 8 miles upstream, and the drainage area is nearly 200 square kilometers. It is necessary to determine the specific corpse throwing. The location is not easy."
"There are dozens of villages on both sides of the river, and the workload of investigation is too great." Li Hui echoed.
"Since the investigation is very difficult, we will start looking for the most likely place to throw the body." Zheng Kaixuan took a pencil and drew an x on a river-crossing bridge upstream:
"There are two cross-river bridges in the upper reaches of the Moon River. Let's start the investigation from these two bridges."
"Team Zheng, do you have any basis, or have you found some clues, why do you think the suspect will throw the corpse from the bridge?" Sun Xing doubted.
Zheng Kaixuan did not find any new clues. This is just a speculation based on his experience. He asked, "Sun Xing, if you are a criminal suspect and you want to throw the body in the river, which position would you choose? "
Sun Xing pondered for a moment: "Just like Han Bin said, this is a scenic area with a lot of people visiting. I will definitely not throw corpses here; I should walk up the river and find a place. Where there is no one, throw the body into the river."
"This method of throwing corpses has a certain degree of difficulty. There are no straight roads on both sides of the Moon River. Your car will not be able to drive through. It will be very inconvenient to carry the corpses; and the rivers on both sides of the Moon River are very steep. The corpse was transported to the river, but it was just thrown to the edge of the river. The water level was very shallow, and the corpse was tied to a heavy object. It was very likely that it was stranded and was discovered long ago." Zheng Kaixuan analyzed the corpse thrown in the river, and pointed again. Bridge across the river:
" It’s much simpler to throw a corpse on the bridge. The car drives directly onto the bridge. The trunk may be only a few meters away from the edge of the bridge; the most important point is that it can be thrown directly to the center of the river. The water level is deep and heavy objects are tied. Sink directly to the bottom."
Han Bin listened with gusto. The possibility of throwing the corpse on the bridge is very high. If the rope of the headless corpse is not broken, the corpse will not be washed downstream by the water, and the case will not be discovered.
"Awesome, worthy of the Zheng team, I didn't expect it." Li Hui's flattery was straightforward, without any concealment.
Zheng Kaixuan looked speechless, can he be a bit technical?
"Team Zheng, your speculation is reasonable. I also think that the suspect may throw the body on the bridge, but it is not easy to determine this." Han Bin took out the cigarettes and gave them a circle.
"Can you go directly down the river to salvage, maybe you can find the head of the corpse." Wei Zimo suggested.
"The water level of the Moon River is high and the current is relatively rapid. If you want to go down the river to fish, the upstream gate must be closed. If you can't provide evidence, it is difficult to apply to higher leaders based on my personal speculation. "Zheng Kaixuan said.
The function of the gate is to control the water level and flood discharge. If something goes wrong, it is not a trivial matter.
"No wonder the suspect likes to throw corpses into the river. The river water is a natural barrier. We can only look at it and search it." Sun Xing sighed.
"Fortunately, it is not the Yellow River or the Yangtze River, otherwise we can only die of this heart." Li Hui smiled.
"We knew that we should find the source of the corpse. Maybe the family of the deceased has been reported missing." Wei Zimo said.
"Don't talk about these useless things, think about clues." Zheng Kaixuan scolded.
"There should be surveillance on the bridge," Sun Xing said.
"It's hard to say. Besides, there are blind spots in surveillance. Who will throw a corpse at the camera." Wei Zimo thought it might not be too big.
After everyone was silent for a while, Han Bin said: "I have a stupid way, maybe I can find some clues."
"Don't care if you are spiritual or stupid, as long as you can find a clue." Zheng Kaixuan said.
"There is monitoring on the bridge, which is naturally the easiest way to view the monitoring of the bridge; but if there is no monitoring on the bridge, we can check the monitoring around the bridge, classify according to different driving directions, and record the average time of car driving between the two monitoring. Even if it’s easier to throw a corpse on a bridge, the suspect has to observe the surroundings. The car will definitely not drive too fast. The corpse will be thrown when there is no one. It also takes a certain amount of time to park, move, and throw the body into the river. It must take more time than other vehicles driving in the same direction." Han Bin said.
"Hey, this method is stupid enough." Li Hui spread his hands.
"Stupid is a bit stupid, but as long as we check carefully, we may really find a clue." Wei Zimo muttered.
"There are so many clever methods in the criminal investigation business. The suspects are not stupid. They have avoided the methods that can be easily caught." Zheng Kaixuan agreed.
According to his experience in handling cases, more than 70% of cases are solved by clumsy methods.
"The two bridges, one is about 4 kilometers upstream, the other is about 11 kilometers upstream, and there is a turning backwater bay about 8 kilometers away from here. If you throw a body from the bridge 11 kilometers upstream, there is It must be stranded in the Backwater Bay, so it is more likely to throw a dead body on a bridge 4 kilometers away. Let's focus on the police to investigate the bridge first." Zheng Kaixuan arranged.
Everyone nodded, all agreeing to Zheng Kaixuan's arrangement.
"Team Zheng, I suggest to copy the surveillance video around the two bridges before the official comparison of surveillance. The time for the deceased to be killed is about 20 days, and the time for the corpse to be thrown may also be about 20 days. The surveillance hard disk is likely to be overwritten." Han Bin worried.
"Yes, I was very considerate." Zheng Kaixuan nodded and ordered:
"Han Bin and Li Hui collected surveillance near the 4km bridge; I took Wei Zimo and Sun Xing to collect surveillance near the 11km bridge; by the way, I visited the surrounding people. On August 30th, did you see What's wrong.
"Yes."
Everyone agreed and acted separately.
Wei Zimo drove the car and put Han Bin and Li Hui near the four-kilometer bridge, while Zheng Kaixuan and the three continued to rush to the upstream bridge.
After and Han Bin got off the car, they first observed the bridge. There was a stone monument standing next to it, with three large characters on it, Tong'an Bridge, and a few rows of small characters next to it, introducing the bridge and the construction time.
The Tongan Bridge is nearly 100 meters long, with two rows of lanes on the left and right sides, and a sidewalk on the outermost side. There is a guardrail about one meter high on the outside of the bridge to prevent pedestrians from accidentally falling.
Han Bin and two walked around the bridge, the water under the bridge was turbulent, and occasionally boats passed by, but nothing unusual was found.
What makes Han Bin happy is that a surveillance system is installed on the north side of the bridge. It is very likely that the suspect's vehicle will be photographed. However, this surveillance does not belong to the traffic police team, but is under the jurisdiction of the Transportation Bureau.
Han Bin immediately contacted Zheng Kaixuan and asked him to come forward to call for surveillance. Zheng Kaixuan called the Transportation Bureau, which was more useful than a trip with Li Hui himself.
Then, Han Bin and the two searched the roads on both sides with the bridge as the center, and copied the surveillance of nearby shops on the street.
Twenty days have passed since the corpse was thrown, and the time has passed too long. After a round of visits, almost no one remembers what happened during that time.
returned to the branch, it was already more than six o'clock in the afternoon.
Han Bin and the two did not return to the second group office, but went to the temporary office of the special case team, which is also in the criminal investigation building, but the second group is on the second floor and the temporary office is on the third floor, which is cleaner.
The office area is very large~IndoMTL.com~There are more than a dozen desks. Zheng Kaixuan and others have not returned yet, and a group of people are not in the office. Only Han Bin and Li Hui are empty.
was not idle either, they started to sort out the collected monitoring, and only made a topographic map near the bridge, and pasted the number of each monitoring, so that it is more convenient for comparison.
These are only the monitoring of the shops, and the Skynet monitoring will be called up later. If you don’t sort and classify, you will be confused first, let alone compare the time taken for each vehicle to cross the bridge.
Around seven o'clock in the evening, Zheng Kaixuan and the three returned to the temporary office. In addition to bringing back the surveillance near another bridge, they also went to the Traffic Management Bureau and brought back the video surveillance of Tongan Bridge.
Li Hui immediately checked the surveillance of Tong'an Bridge. However, what is depressing is that the surveillance of Tong'an Bridge 20 days ago has been covered, and only the surveillance video of September 4 can be seen at the earliest.
This is just the beginning. Li Hui checked some store surveillances. Most surveillance hard drives can only be stored for about fifteen days. The previous surveillance videos are covered.
Zheng Kaixuan's expression remained as usual. He saw more of this situation, and the clues of many cases were broken after investigation. He asked Sun Xing to send the video to the technical team to try to restore the covered surveillance content. In this regard, He didn't report much hope either.
Fortunately, Skynet's monitoring storage can last for about a month, and you can also look for new clues...
