Detective from the Future

3rd Corps men returned to police van.
　　
Zheng Kaixuan sat in the second row, spread out a map of Moon River, and circled with a pencil: “This is where we are now, located downstream of Moon River, and the width of the river bed is more than a hundred meters . “
　　
Han Bin observed the map, pointing to the upstream river:
　　
“The Moon River is more than 30 kilometers in length, and the channel is not straight. There are always 8 miles upstream. There will be an angle of almost 90 degrees. The watershed area is nearly 200 square kilometers. It is not easy to determine the location of the dead body. “
　　
“There are dozens of villages on the two sides of the river, and the investigation workload is too much,” Li Hui echoed.
　　
“Since the investigation is difficult, let’s search from the place where the body is most likely to be thrown.” Zheng Kaixuan took a pencil and drew a × on a cross-river bridge upstream:
　　
“There are two bridges across the river upstream of the Moon River. Let’s start investigations from these two bridges.”
　　
“Chief Zheng, what basis do you have, or do you find any clues, why do you think the suspect will throw the corpse from the bridge?” Sun Xing wondered.
　　
Zheng Kaixuan not at all found new clues, which were only speculations based on his experience. He asked: “Sun Xing, if you are a criminal suspect, you want to throw corpses in the river, which location would you choose?”
　　
Sun Xing pondered for a moment: “Like Han Bin said, there is a scenic area nearby, and there are many people playing. I definitely won’t leave the body here; I should go up the river and find a place without people Place, throw the body into the river. “
　　
“There is a certain degree of difficulty in throwing dead bodies. There is no straight road on the Moon River 2 side, and your car simply cannot drive through, it will be very inconvenient to carry dead bodies; and the river channel on the Moon River 2 side is very steep, even if you barely carry the dead body to The river was just thrown to the edge of the river, the water level was very shallow, and the body was heavy, and it was likely to be stranded. It was already discovered. “Zheng Kaixuan analyzed the river tossing the dead body and pointed to the bridge across the river:
　　
“Throwing dead bodies on the bridge is much simpler. The car drives directly onto the bridge, and the trunk may be only a few meters away from the edge of the bridge. The most critical point can be directly thrown to the center of the river. . “
　　
Han Bin heard with keen interest pleasure, the bridge is very likely to throw corpses. If the rope of the headless corpse’s weight is not broken, the corpse will not be washed downstream by the current, and the case will not be found.
　　
“It’s amazing, it’s Chief Zheng. Why did I didn’t expect it?” Li Hui’s flattery was very straightforward, without any concealment.
　　
Zheng Kaixuan was speechless and could be a bit technical.
　　
“Chief Zheng, your speculation is reasonable. I also think that the suspect may throw a corpse on the bridge, but it is not difficult to determine this.” Han Bin took out a cigarette and sent a circle to everyone.
　　
“Can you go down the river to salvage, maybe you can find the body’s head.” Wei Zimo suggested.
　　
“The water level of the Moon River is relatively high, and the current is also relatively urgent. If the river is to be caught for fishing, the upstream gate must be closed. If no evidence is available, it is difficult to apply to a superior leader based on my own 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 in the river. The river water is a natural barrier. We can only look at it and want to search it.”
　　
“Fortunately, it is not the Yellow River or the Yangtze River, otherwise we can only die this heart.” Li Hui laughed.
　　
“If we knew that we should find the source of the corpse, maybe the family members of the deceased have reported missing.” Wei Zimo said.
　　
“Don’t talk about these useless, think about clues.” Zheng Kaixuan scolded.
　　
“There should be monitoring on the bridge,” Sun Xing said.
　　
“It’s impossible to say, let alone surveillance has dead ends, who will throw the body at the camera.” Wei Zimo thought it might not be big.
　　
After a few moments of silence, Han Bin opened the mouth and said: “I have a stupid way, maybe I can find some clues.”
　　
“Don’t worry if it’s spiritual or stupid, as long as you can find a clue,” Zheng Kaixuan said.
　　
“There is monitoring on the bridge, naturally it is the easiest 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 2 monitoring. Even if it is easier, the suspect must observe all around. The car will certainly not drive too fast. When there is no one, throwing the corpse, and parking, moving, and throwing the river will take some time. It takes more time than other vehicles traveling in the same direction, “said Han Bin.
　　
“Tsk tsk, this method is stupid enough.” Li Hui spread his arms.
　　
“Stupid is a bit stupid, but as long as we check carefully, we may really find clues.” Wei Zimo whispered.
　　
“Criminal Investigation is where there are many clever ways. Suspects are not stupid. They can be easily caught. They have long avoided it.” Zheng Kaixuan agreed.
　　
According to his experience in handling cases, more than 70% of cases are solved by clumsy methods.
　　
“These two bridges, one is about 2 kilometers upstream, and the other is about 4 kilometers upstream, and there is a bend back to the water bay about 11 kilometers from here. It was stranded in Huishui Bay, so it ’s more likely that a corpse will be thrown on the bridge 8 kilometers away. Let ’s focus our police on investigating the bridge first. ”Zheng Kaixuan arranged.
　　
Everyone was nodded and agreed with Zheng Kaixuan’s arrangement.
　　
“Chief Zheng, I recommend copying the surveillance videos around the two bridges before the official comparison of the surveillance. The time of the deceased’s killing is about 2 days, and the time of the dead body may also be about 20 days. Will be covered. “Han Bin worriedly said.
　　
“Yes, very thoughtful.” Zheng Kaixuan nodded, instructed:
　　
“Han Bin and Li Hui collected surveillance near the 4 km bridge; I took Wei Zimo and Sun Xing to collect surveillance near the 11 km bridge; by the way, I visited the surrounding people. On August 8, did I see any abnormalities?
　　
“Yes.”
　　
The people promised and acted separately.
　　
Wei Zimo drove a car and placed Han Bin and Li Hui near the 4 km bridge, while Zheng Kaixuan and 3 others continued to drive to the upstream bridge.
　　
After Han Bin 2 got out of the car, they first looked at the bridge. A stone monument stands next to it, with three large characters on it, and a few rows of small characters next to it. It is the introduction and construction time of the bridge.
　　
The Tongan Bridge is nearly 100 meters long, with two rows of lanes on each of the left and right sides, and a sidewalk on the outermost side. There is a one meter high and a left and right guardrail on the outside of the bridge to prevent pedestrians from accidentally falling.
　　
Han Bin 2 walked around the bridge, the water was turbulent under the bridge, and occasionally a boat passed by, but not at all found anything abnormal.
　　
Han Bin was pleased that a monitor was installed on the north side of the bridge, and the suspect’s vehicle was likely to be photographed. However, this monitoring is not part of the traffic police team, but is under the jurisdiction of the traffic bureau.
　　
Han Bin immediately contacted Zheng Kaixuan and asked him to come in for monitoring. Zheng Kaixuan called the traffic bureau, which was more useful than a trip with Li Hui himself.
　　
Subsequently, the Han Bin 2 searched for the road on the 2 side with the bridge as the center, and copied the monitoring of the nearby street shops.
　　
It has been 20 days since the corpse was thrown, and time has passed too long. After a visit, few people remember what happened during that time.
　　
Back to the branch station, it is already over 6pm.
　　
The Han Bin 2 did not return to the 2nd Squad office, but went to the temporary office of the task force. This office is also in the Criminal Investigation Building, but 2nd Squad is on the second floor and the temporary office is on the third floor, which is more clean.
　　
The office area is very large, UU reading www.uukanshu. There are more than a dozen desks in com. Zheng Kaixuan and the others have not yet returned. The people at 1st Squad are not in the office. Only Han Bin and Li Hui are empty.
　　
Two people were not idle, and started to organize the collected monitoring, and only made a Terrain Map near the bridge, and pasted the number of each monitoring, which was more convenient for comparison.
　　
These are just the monitoring of the shops, and Skynet monitoring will be called later. If it is not sorted and classified, it will be confused by itself, not to mention the time required for each vehicle to cross the bridge.
　　
Around 7 pm, Zheng Kaixuan returned to the temporary office. In addition to bringing back the monitoring 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 monitoring of Tong’an Bridge, but it was depressing that the monitoring of Tong’an Bridge 20 days ago had been covered, and only the surveillance video of September 9th could be seen at the earliest.
　　
This is just the beginning. Li Hui also looked at some store surveillance. Most surveillance hard drives have limited storage and can only be kept for about 5 days. The previous surveillance videos are covered.
　　
Zheng Kaixuan expression As usual, he saw this situation a lot, and the clues of many cases were found after investigation. He asked Sun Xing to send the video to the technical team, and tried to restore the coverage of the monitored content. The report is too hopeful.
　　
Fortunately, Skynet monitoring storage can be maintained for about a month, and you can also find new clues …
