Lu Li and Zhou Jie began sampling.

Lu Li took out the water collection pipe from the sampling box and collected several water samples at different locations in the wastewater tank.

Zhou Jie collects biological specimens such as dead grass and leaves around the wastewater pond.

Gu Yanan asked the village chief about the specific situation of the mine.

Gu Yanan asked: "Do you know the worker just now?" ”

Village Chief: "Know, it is our Jinshan Village, his name is Li Yuanfeng, his family has three brothers, he is the third, usually the village people call him San'er, before his three brothers are working in the mine, and then the eldest and the second brother have been sick, in the first half of the year, less than a month apart, are inexplicably sick and died, at the beginning of this month, San'er's old mother also died of cancer, pitiful, his father died early, and now he is the only one left in the family. ”

The village chief sighed as he spoke.

Gu Yanan looked at the figure of the young man next to the machine, and his heart was not happy.

Gu Yanan continued to ask the village chief, "A family of four, three died, why?" ”

"People in the village say that San'er's two elder brothers were choked to death by the ashes because they worked in the mine, and it is said that when they died, their lungs were like loofahs.

As for San'er's old mother, the situation is similar to other people in the village, Li Yuanshan's wife Li Jinhua fell ill because of cadmium poisoning, and San'er's old mother has symptoms very similar to her. ”

Judging from what the village chief said, Gu Yanan speculated that Jinshan Village was already very seriously polluted by the mine, but there was specific evidence, and that was the test results of this sampling.

Soon, Zhou Jie and Lu Li were sampling samples around the wastewater pond.

Gu Yanan: "Village Chief, the mine you said secretly discharged wastewater into the cave, where is the cave?" ”

"Come with me, the cave is really hard to find, it's in a forest next to the mine, and there are pipes leading from the mine to the edge of the cave."

Led by the village chief, Gu Yanan and his party walked through a small forest next to the mine and found a cave under a hidden mountain depression.

At the mouth of the cave there are two pipes thicker than an arm, which extend from the side of the mine.

From time to time, brown liquid flowed out of the tube.

The liquid enters the pool at the mouth of the cave, because the cave is located in the low-lying part of the mountain forest, and there is a stream of water flowing down from the mountain to gather here, and the wastewater is washed by the water flow into the depths of the cave.

The small pool at the entrance of the cave has a significant difference in color from the water flowing downstream.

The mountain stream upstream is clear, and the waterhole at the mouth of the cave has been stained brown by the wastewater flowing through the pipes.

In the waterhole at the mouth of the cave, there are still a few dead rats and discarded plastic bags of garbage, emitting a foul smell.

Lu Li frowned and stared at the dirty pond at the mouth of the cave, "Village Chief, where did the water in this cave end up?" ”

"There is no exit, and the water from the cave has flowed into the ground."

Gu Yanan's brows also furrowed.

That's the rhythm of polluting groundwater.

Without waiting for Gu Yanan's orders, Lu Li and Zhou Jie had already begun to prepare tools for sampling.

The cave is more than one person high, but because of the obstruction of the waterhole at the entrance of the cave, everyone cannot enter the cave.

Gu Yanan stood by the waterhole and looked into the cave.

The cave was dimly lit, but you could still see something floating on the dark water.

The village chief saw that Gu Yanan had been staring into the cave, and he couldn't help but look in the same direction.

There was a black mass floating on the dark water.

The village chief muttered to himself, "Such a big mass of things, it can't be a dead pig, right?" ”

The village chief took an old bamboo pole from the edge of the waterhole and tossed at the black mass in the depths of the cave.

The mass was gradually pulled out of the cave, and before it reached the edge of the waterhole, the village chief and Gu Yanan were startled.

Not a dead pig, but a dead man!

Lu Li and Zhou Jie, who were sampling by the waterhole, stood up and stared at the dead bodies floating in the waterhole, and they were so frightened that they took a step back.

The corpse was floating face up in the pool, wearing a black suit, with a swollen and pale complexion, very human.

The village chief was bold and looked at the dead body, and after a moment, exclaimed, "Isn't this the mine owner?" How could you die here? ”

Gu Yanan didn't know what the situation was, and this was the first time that he encountered a dead body in sampling.

Gu Yanan said to the people around him, "Try not to damage the surrounding environment, call the police!" ”

More than two hours later.

Police cars whizzed in.

It was the police who came with Nan Hanfei.

Nan Hanfei was also surprised to see Gu Yanan and Lu Li in such a remote mountain mine.

Nan Hanfei asked Gu Yanan about the circumstances when the body was found, and asked him to make a record.

The forensic doctor from the police force began to observe the body at the scene.

Soon, the police team's investigation of the scene was completed.

The body was taken back to the forensic center by the police.

Nan Hanfei also had to question and investigate the employees of the mine and nearby villagers, and Gu Yanan was in a hurry to return to the CDC laboratory to test the cadmium content of the collected samples, so the two teams left separately.

On the way back to the CDC, Lu Li sighed while driving, "This mine owner should be very rich, it rained heavily yesterday, how could he come to the mine?" Still dead in a cave that discharges wastewater? Could it be that because he was concerned about the operation of the mine, he fell into a pool and drowned while checking the discharge of wastewater? ”

Zhou Jie sat in the back seat of the car and shook his head, "It shouldn't be, the waterhole next to the cave is very shallow, I tried it with a bamboo pole, and it is only more than half a person high, how could I drown the mine owner as an adult?" ”

Gu Yanan also analyzed, "When the forensic doctor of the police team was disposing of the corpse just now, I was not far away, and I saw an obvious strangulation mark under the mine owner's neck, the corpse was soaked white, and the strangulation mark was blue and purple, which was very conspicuous in the contrast of the miserable white skin. ”

"Strangulation? Was he strangled to death? ”

"It should be."

"Oh my God, it's not an accidental death, it's murder."

"Who's going to kill the mine owner?" Lu Li thought in his heart who might be the murderer.

"If the cause of the villagers' illness in Jinshan Village is really cadmium poisoning caused by the mine, then there is a high probability that he will be killed for a vendetta."

Zhou Jie glanced back at the sample placed in the trunk of the car, "Our test results have not yet come out, and we are not sure." ”

Gu Yanan was a little worried, "Sometimes people's actions don't need definite evidence, as long as they think it is in their hearts, then it is. ”

Lu Li understood what Gu Yanan meant, he had just been diagnosed with cadmium poisoning yesterday, and this morning he found that the mine owner had died in the cave pool where the wastewater was discharged.

Isn't there a connection between the two?

Lu Li thought about it, his back was cold, and he sighed: "Anyway, it is illegal to kill people directly, and it makes people scary when they think about it, in fact, they can solve the pollution of the mine in many ways." ”

Zhou Jie: "Whether it's a vendetta or a robbery, I don't know yet, these things are in the hands of the police."

Lu Li, you don't care about any environmental pollution, we just do our job well, or hurry back to test these samples and give them to the relevant departments as a basis, this is our business. ”
