Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 450 The disappearance case of that year
Haizhou City Criminal Investigation Detachment.

After taking a nap for 4 hours, Lu Chuan and others recovered a little bit of blood.

Although I am still very tired, I should be able to survive the rest of the night.

It was already dusk outside, the sky was getting dark, and the search team would be ready to set off in a while.

After the case analysis meeting at noon, Qin Yong had arranged for a group of people to deal with the weeds under the Shishan Bridge.

The discovery of Wang Mingshan's body early this morning was partly due to the variable frequency laser spectrum analyzer used by Lu Chuan.

Another aspect is that the location where the other party buried Wang Mingshan is relatively close to the shore. In this case, the search difficulty is relatively small.

But now if we want to conduct the entire search under the Lion Rock Bridge, the scope will be much expanded. If there are still so many weeds, it will definitely affect the search progress.

So on the one hand, the local police station was responsible for martial law, and on the other hand, a group of people were found to deal with the weeds in advance.

At the same time, Lu Chuan took out two spare frequency conversion laser spectrum analyzers.

This is all the laser equipment belongings in the current investigation office of the Haizhou City Criminal Investigation Detachment.

It would certainly not be a problem for Lao Bai and Yang Sen to use a variable frequency laser spectrum analyzer. The key is that they don't have much control over the debugging frequency.

Last night, Lu Chuan studied for a long time before determining the laser frequency that could react specifically with phosphorus.

This is experience.

It was the skills brought to Lu Chuan by the system that came into play.

Regarding gas chromatography, not everyone has heard of it, but if you have a little more chemical knowledge and a slightly higher level, you will also know this method, but what kind of laser does phosphorus work with, and what kind of laser frequency can When an idiosyncratic reaction occurs, not everyone can know about it.

After Lu Chuan adjusted the corresponding frequencies of the three variable-frequency laser spectrum analyzers, he carried one himself, the other two were Lao Bai and Yang Sen.

At seven o'clock in the evening, when it was completely dark, the search team set off.

"Lao Bai, do you think you can gain something this time?"

In the car, Yang Sen was holding the instrument and chatting with Lao Bai.

"I think... it's very possible."

"How to say?"

"Think about it, why was Wang Mingshan killed? Before Wang Mingshan was killed, he was investigating the disappearance of a policeman. So where is that policeman now?"

"Since Wang Mingshan has been confirmed to have been killed, there is a high probability that the policeman has also been killed."

"Also, don't forget, when we analyzed Wang Mingshan's skeleton this morning, we found many old injuries and blunt force injuries."

"The murderer tortured Wang Mingshan before burying him alive, so why did he torture Wang Mingshan?"

"Did Wang Mingshan discover something?"

"It's not like you don't know what happened at Songbei Mining back then, so I think there's a big deal behind it."

Although Qin Yong did not tell his subordinates about the pressure he was facing, the Songbei Mining incident was widely spread at that time. Although it was not publicly reported, everyone who was well-informed knew about it.

"You mean...the mining accident?"

"Huh, in such a big accident, do you believe that no one was killed?"

"Why did that policeman disappear back then? Have you heard about it?"

Yang Sen nodded.

The policeman who disappeared that year was a policeman from Songbei Police Station. His younger brother originally worked in Songbei Mining and was the team leader of a mining team.Later, after a mining accident occurred in Songbei Mining, the person disappeared.

At that time, the policeman went to investigate, but the person disappeared within a few days.

"It is said that no one was killed in such a big mining accident, but the leader of a mining team disappeared. Who would believe it?"

"The policeman just went to check, but he disappeared within a few days."

"The policeman disappeared. Songbei reported the case to our criminal investigation detachment. The second operation team was following. Wang Mingshan was specifically responsible. However, he also disappeared while investigating Songbei Mining."

"Now, the person is found under the Lion Rock Bridge. Do you think he can be the only one under the bridge?"

Liu Guodong leaned back in his seat, closed his eyes and rested, and did not participate in the chat between Yang Sen and Lao Bai.

As the head of the current investigation office, he actually knows more about the case five years ago than Yang Zi and Lao Bai.

Back then, the disappearance of a police officer from the police station was no longer a trivial matter. As a result, after the case was reported to the Criminal Investigation Detachment, a criminal police officer investigating the case disappeared one after another.

In fact, it is not an exaggeration to say that this kind of thing is shocking.

The criminal investigation detachment indeed made great efforts that year, and the entire team was dispatched to investigate the case of Wang Mingshan's disappearance.

At that time, there was not enough manpower, so the current survey office was mobilized. Liu Guodong participated in the investigation inside.

Moreover, when the case analysis meeting was held, Liu Guodong also participated.

Many guesses and reasoning are much more straightforward than what Yang Sen and Lao Bai said.

But there was no way. Songbei Mining did not find any problems back then.

According to surveillance records from that year, the surveillance video of Wang Mingshan entering Songbei Mining Company on the day of his disappearance and the video coming out are complete.

The other party went in intact, came out intact, and disappeared on the way back to the unit. What does it have to do with Songbei Mining?
Even so, Qin Yong turned Songbei Mining upside down despite pressure from all parties, but still found nothing.

After nearly two months of back and forth, Songbei Mining was once shut down, but nothing was discovered.

In fact, even if there is a little clue, it is good, but there is no clue. If a star company is like that, someone above it will talk.

Liu Guodong still remembered that Qin Yong went to Song Jiangguo's office to quarrel more than once because of this matter.

But there is no way, no clues, no evidence, we cannot keep investigating Songbei Mining.

then……

That's it for now.

Even now, there is no evidence that Wang Mingshan's death is related to Songbei Mining.

Not only Qin Yong knows this clearly, but everyone also knows it, so the main direction of solving the case now is to use Ren Qiang's car accident as a breakthrough point.

As long as you find this person and follow the clues, you might be able to find out the tail of the shady story behind it.

Lao Bai and Yang Sen chatted, and when everyone drove to the Lion Rock Bridge, the work of the Liangzhou City Criminal Investigation Detachment made greater progress.

The man in the hooded sweatshirt showed his true face in the hotel, and it would not be so easy to run away again.

The Liangzhou City Criminal Investigation Detachment was really good at it. After confirming the other party's appearance, they started a comprehensive investigation.

With the current density of surveillance video distribution, it is difficult for the other party not to be caught without carefully planning the route in advance.

So intermittently, the whereabouts of the man in the hooded sweatshirt were finally determined.
