Detective from the future

Chapter 154 Difficulties
Three teams returned to the police van.

Zheng Kaixuan sat in the second row, spread out a map of the Moon River, and drew a circle with a pencil: "This is where we are now. It is located in the lower reaches of the Moon River. The width of the river bed is more than 100 meters."

Han Bin observed the map and pointed to the river upstream:
"The Moon River is more than 30 kilometers long, and the river course is not a straight line. If you go 8 miles upstream, there will always be a bend angle of nearly 200 degrees. The drainage area is nearly [-] square kilometers. It is not easy to determine the specific place to dump the body. .”

"There are at least dozens of villages on both sides of the river, and the investigation workload is too great." Li Hui echoed.

"Since the investigation is difficult, let's start looking for the place where the body is most likely to be dumped." Zheng Kaixuan took a pencil and drew an X on a bridge across the river upstream:

"There are two river-crossing bridges in the upper reaches of the Moon River. Let's start our investigation from these two bridges."

"Captain Zheng, do you have any basis, or have you found any clues, why do you think the suspect will throw his body from the bridge?" Sun Xing asked doubtfully.

Zheng Kaixuan didn't find any new clues. This was just a speculation based on his experience. He asked: "Sun Xing, if you were a criminal suspect and you wanted to throw the body in the river, which location would you choose?"

Sun Xing pondered for a moment: "As Han Bin said, this area is a scenic spot, and there are many people visiting it. I will definitely not throw the corpse here; I should go up the river and find a place where there are no people. place, throw the body into the river."

"This method of dumping corpses is difficult. There are no straight roads on both sides of the Moon River, and your car will not be able to drive across it. It will be very inconvenient to carry the corpses; moreover, the rivers on both sides of the Moon River are very steep, so even if you barely transport the corpses When they reached the river, they were just thrown to the edge of the river, the water level is very shallow, and the corpse is tied with heavy objects, it is likely to be stranded, and it has been discovered long ago." Zheng Kaixuan analyzed the corpse thrown in the river, and then pointed to the bridge across the river :

"It's much easier to throw a corpse on the bridge. The car drives directly onto the bridge, and the trunk may only be a few meters away from the edge of the bridge; the most critical point is that it can be thrown directly to the center of the river, where the water level is deep and heavy objects are attached to it. .”

Han Bin listened with gusto. The possibility of dumping the body on the bridge was very high. If the ropes tied to the headless body with heavy objects had not been broken, the body would not have been washed downstream by the current, and the case would not have been discovered.

"Excellent, as expected of Team Zheng, why didn't I expect that." Li Hui's flattery was very direct, without any intention of covering up.

Zheng Kaixuan was speechless, could he be a little technical.

"Captain Zheng, your speculation is reasonable. I also think that the suspect might throw his body on the bridge, but it is not easy to be sure." Han Bin took out a cigarette and distributed it to everyone.

"Can you go directly to the river to salvage, maybe you can find the head of the corpse." Wei Zimo suggested.

"The water level of the Moon River is relatively high, and the current is relatively fast. If you want to go fishing in the river, the upstream gate must be closed. If you can't produce evidence, it is difficult to apply to the superiors based on my personal speculation." Zheng Kaixuan Said.

The function of the gate is to control the water level and discharge the flood. If there is a problem, it is not a trivial matter, and it is not easy to move it.

"No wonder suspects like to throw their bodies into the river. The river is a natural barrier. We can only watch and search." Sun Xing sighed.

"Fortunately, it's not the Yellow River or the Yangtze River, otherwise we'd have no choice but to die." Li Hui laughed.

"We should have searched for the source of the corpse if we knew it earlier, maybe the family members of the deceased have already reported him missing." Wei Zimo said.

"Don't talk about these useless things, think more about clues." Zheng Kaixuan scolded.

"There should be monitoring on the bridge." Sun Xing said.

"It's not certain. Besides, there are blind spots in the monitoring. Who would throw the body at the camera." Wei Zimo thinks it may be unlikely.

After everyone was silent for a while, Han Bin said, "I have a stupid way, maybe I can find some clues."

"It doesn't matter if it's smart or stupid, as long as you can find a clue, tell it." Zheng Kaixuan said.

"There is monitoring on the bridge, so it is naturally the easiest way to check 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, record the average time of driving between the two monitoring, and dump the body on the bridge. Even if it is easier, the suspect has to observe the surroundings. The car will definitely not drive too fast, and then throw the body when no one is there. In addition, it will take a certain amount of time to park, carry, and throw it into the river. Other vehicles traveling in the same direction spend more time," Han Bin said.

"Tsk tsk, this method is stupid enough." Li Hui spread his hands.

"Stupid is a bit stupid, but as long as we investigate carefully, we may really find clues." Wei Zimo muttered.

"How can there be so many clever methods in the criminal investigation industry? Criminal suspects are not stupid. They have long avoided methods that can be easily caught." Zheng Kaixuan agreed.

According to his experience in handling cases, more than 70.00% of the cases are solved by stupid methods.

"These two bridges, one is about 4 kilometers upstream, the other is about 11 kilometers upstream, and there is a backwater bay about 8 kilometers away from here. If the body is thrown from the bridge 11 kilometers upstream, there is a certain possibility It ran aground in Huishui Bay, so it is more likely that the body will be dumped on the bridge 4 kilometers away from here, so let's concentrate the police to investigate the bridge first." Zheng Kaixuan arranged.

Everyone nodded, agreeing with Zheng Kaixuan's arrangement.

"Team Zheng, I suggest copying the surveillance video around the two bridges before formally comparing the surveillance. It took about 20 days for the deceased to be killed, and it may take about 20 days for the body to be dumped. It is very likely that the surveillance hard drive It will be covered." Han Bin worried.

"Not bad, very thoughtful." Zheng Kaixuan nodded and ordered:
"Han Bin and Li Hui collected the monitoring near the 4km bridge; I took Wei Zimo and Sun Xing to collect the surveillance near the 11km bridge; by the way, I visited the surrounding people around NO.8 in August, did they see anything unusual.

"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 others continued to rush to the upstream bridge.

After Han Bin and his wife got off the car, they first observed the bridge. There was a stone tablet next to it, with three large characters written on it, Tong'an Bridge, and a few rows of small characters beside it, which were the introduction of the bridge and the time when it was built.

The Tongan Bridge is nearly [-] meters long, with two rows of lanes on the left and right sides, and sidewalks on the outermost side. There is a guardrail about one meter high on the outside of the bridge to prevent pedestrians from accidentally falling.

The two of Han Bin walked around the bridge. The water flow under the bridge was turbulent, and occasionally a boat passed by, but they didn't find anything unusual.

To Han Bin's delight, a surveillance camera was installed on the north side of the bridge, which is likely to capture the suspect's vehicle, but this surveillance does not belong to the traffic police team, but is under the jurisdiction of the Traffic Bureau.

Han Bin immediately contacted Zheng Kaixuan and asked him to come forward to obtain the monitoring. Zheng Kaixuan called the Transportation Bureau, which was more useful than a trip by himself and Li Hui.

Afterwards, Han and Bin searched the roads on both sides around the bridge, and copied all the surveillance cameras of nearby shops facing the street.

It has been 20 days since the body was dumped. It has been too long. After visiting around, almost no one remembers what happened during that time.

When we returned to the branch office, it was already past six o'clock in the afternoon.

Han Bin and the two did not go back to the office of the second team, but went to the temporary office of the special case team. This office is also in the Criminal Investigation Building, but the second team is on the second floor, and the temporary office is on the third floor, which is cleaner.

The office area is very large, with more than a dozen desks. Zheng Kaixuan and others have not returned yet, and a group of people are not in the office either. Only Han Bin and Li Hui are empty.

The two were not idle, and began to sort out the collected monitoring, and only made a topographic map near the bridge, and pasted the number of each monitoring, which made it easier to compare.

These are just the monitoring of the shops, and the monitoring of Skynet will be called in a while. If you don’t organize and classify them, you will get confused first, let alone compare the time it takes for each vehicle to cross the bridge.

At around seven o'clock in the evening, the three of Zheng Kaixuan returned to the temporary office. In addition to bringing back the surveillance cameras near another bridge, they also went to the Traffic Management Bureau and brought back the video surveillance of Tong'an Bridge.

Li Hui immediately checked the monitoring of Tong'an Bridge, but what was depressing was that the monitoring of Tong'an Bridge 20 days ago had been covered, and only the surveillance video of September 9 could be seen at the earliest.

This is just the beginning. Li Hui checked some store surveillance. Most of the surveillance hard disks have limited storage and can only be kept for about [-] days. The previous surveillance videos have been overwritten.

Zheng Kaixuan looked as usual. He had seen this kind of situation a lot. The clues of many cases were broken after checking. He asked Sun Xing to send the video to the technical team to try to restore the covered surveillance content. He did not respond to this. Report too much hope.

Fortunately, Skynet's monitoring storage can last for about a month, and new clues can be found...
