Chapter 787 Difficulty

The large factory building was damaged as if it had been bombed.

The red brick exterior wall was dirty and shabby, the ceiling was in tatters, and the concrete pillars used as supports looked okay, but they were covered with graffiti, urine stains and dirt from unknown sources. The floor inside the factory is uneven, sewage flows across the floor, and the feces and urine of humans, dogs, cats, mice, birds, and insects are everywhere.

The relatively complete walls on the east and west sides of the factory building were piled with some bricks and stones and the like, and covered with a few plastic sheets, it turned into a shack that could sleep people.

Zhang Jigu, a man with sunken cheeks who was addicted to drugs, had his hands cuffed and pointed to a corner, saying: "I was lying there with something covering me, and I didn't dare to move."

"Which way are you turning your head?" Meng Chengbiao followed Jiang Yuan, asking for details along the way.

Details are the hardest to make up and the easiest to reveal.

As the saying goes, people cannot imagine what they have never seen. If Zhang Jigu had never seen someone turn into a corpse, he would never have thought of this.

At the identification site, details are the key step that determines success or failure.

Zhang Jigu looked back and said, "The wind is blowing too much in the direction facing away from the door."

Meng Chengbiao walked over, bent down, and looked with his head almost on the ground for a while.

The ground was so dirty, and there were all kinds of bugs scarier than mice, that Meng Chengbiao couldn't lie down.

It also shows that this case so far is not worth adding to the backlog of murder cases.

"What are you covering?" Meng Chengbiao asked again.

Zhang Jigu thought for a while and said: "The sheets and clothes are all piled with paper, the kind of paper used for express delivery. They are piled high to prevent wind. I don't even come out when I sleep."

"What should I do if I need to go to the toilet? What should I do if I pee?" Mu Zhiyang asked.

Zhang Jigu said: "Some people just pee their pants, I mean some people... I usually drink less water and don't go to the toilet at night."

"How long have you been sleeping here?"

"I slept in there that day."

"What time exactly?"

"It's noon, it's quite cold, so I didn't get up, but a few of them arrived. I know one of them, nicknamed Broken Hand, and the three fingers on the back of his left hand were chopped off. He's a ruthless guy, so I'll hide it. move."

"How long have they been transformed into corpses?"

"It's quite a few hours."

"How many hours can you carry so many cardboard boxes and stuff without making any noise?"

"I'm wearing clothes, a down jacket. I'm not a homeless person... I quietly pushed the cardboard box away and hid it behind it." Zhang Jigu became serious and added: "If you don't believe it, I'll give it to you Let’s perform.”

"You will have a chance to perform later." Meng Chengbiao suppressed the person and continued to ask questions.

When Jiang Yuan heard this, he walked towards the corpse's position indicated by Zhang Jigu.

When chemicals are used to dissolve corpses, most people subconsciously think that if the solvent used is appropriate, the corpse will be dissolved quickly.

In fact, no, on the contrary, it takes a certain amount of time to transform into a corpse. If the operation is smooth, it often takes several hours to start. Sometimes, it is necessary to stir or even add chemicals.

Similar to burning corpses, many people think that they can cremate the corpse by just using some fuel or pouring some diesel. In fact, it is not that simple. After burning the corpse a few times, you will understand that combustion accelerants such as diesel are almost necessary. If you want to fully incinerate the corpse, if you don't have professional equipment, it's best to keep an eye on it.

To use a particularly appropriate metaphor, when burning paper for the ancestors, if they were not turned over from time to time, even though the burning flame was very large, there would still be a lot of paper wrapped in the fire and not fully burned. It will take a certain amount of time for them to be completely burned out.

Imagine that 80 kilograms of paper are piled up and burned together. It will also take a lot of time.

Dissolving with a solution is actually the same thing. If you don't cut it into pieces, the solution will dissolve from the outside in. After the outer layer of flesh reacts with the solution, the properties of the outermost solution will naturally change. Whether you use acid or alkali, it is equivalent to being partially neutralized. Therefore, if you want the solvent to dissolve quickly, it is best to have a solvent that can...right.

At this time, another requirement was deduced, that is, it is best to transform into a corpse during the day, at least under good light conditions. Otherwise, these acid and alkali substances will cause pain for two to three months if they splash on the body. .

And in the case of this dilapidated factory, if you turn into a corpse at night, you have to turn on the lights, which is unsafe and easy to be discovered.

Therefore, turning into a corpse during the day seems particularly reasonable.

However, imagining that after turning into a corpse, there will be no trace left, that is another level of fantasy.

Jiang Yuan walked around the open space in the factory building and waved for people to come over.

"The place where waste liquid is dumped." Jiang Yuan pointed.

The acid that can dissolve corpses corrodes the ground so severely that a normal person can see it at a glance.

The two scouts immediately came on stage, put up yellow signs, and started patting.

Jiang Yuan was observing the corroded ground.

This is a huge disadvantage of corpse water.

To solve the problem of waste liquid dumping. It is necessary to neutralize the waste acid liquid, but this requirement is even higher. On the one hand, the operation is more complicated and dangerous. On the other hand, hundreds of kilograms of acid liquid may require hundreds of kilograms of alkali solution to neutralize, and the raw materials will be Got a double portion.

Furthermore, accurate neutralization is basically impossible. The accuracy requirements are too high. But if it cannot be accurately neutralized, how to deal with the remaining acid or alkali?

The better solution Jiang Yuan could think of was to bring excess lye to neutralize the acid, and then carry the remaining lye bottles home.

"Look for where this pipe leads. Start from the dumped position and dig all the way there. Dig 20 meters first and take a look." Jiang Yuan was now speaking very loudly.

Of course, after digging, it is normal to dig a little longer.

Xiao Si listened in front of him and immediately went to make arrangements.

Zhang Jigu, who was in handcuffs, shrank his neck when he heard this. He was also a person who often went in and out of the detention center. After listening to Jiang Yuan's order and looking at the concentration of the police around him, he silently recited Amitabha, feeling that the people in the Duanzhang group were going to be in bad luck. .

The police are quite scary when they take it seriously.

"Here. They should have burned the plastic buckets." Jiang Yuan took a few steps and pointed to another location.

It has to be said that without Zhang Jigu's report, it would be difficult for the police to independently investigate the case here. Most of the traces can have other explanations, including traces of pickling. There are traces of pickling in the old building of the factory. That is not Very reasonable?

Although now it seems that pickling is more similar to dumping, but this requires professional trace inspection to judge, and ordinary policemen are not sure.

Others, such as the traces of burning plastic barrels, etc., do not even need to be explained. In such an old factory where homeless people come and go, it is normal for someone to light a fire to keep warm.

However, if this factory is regarded as a crime scene, various trace detection methods will be used, and there are many traces in this factory.

Especially with Jiang Yuan’s inspection level, it is even easier:

"There may be blood stains here. Check it and call a police dog over."

"Here, the marks on the tool should be that someone was squatting here out of boredom and playing with a knife. He caught them and came back to compare them."

"Change the surveillance nearby."

Jiang Yuan turned around and said to Cui Qishan: "It's basically certain that there was a murder. But there is no body."

In ordinary cases, a homicide investigation will not be opened without a body. In other words, the first step in a murder investigation is to at least find the body.

However, since Jiang Yuan said there was a murder, Cui Qishan and others naturally agreed.

Cui Qishan followed the murder case and thought quickly, saying: "Zhang Jigu knows a drug dealer's younger brother, nicknamed Duanzhang. This is easy to handle. If you ask someone, you will know who is above him. Catch him and interrogate him. This case cannot be hidden. of."

"Okay." Jiang Yuan nodded in agreement.

Catch first if there is one, and DNA if there is no capture, which is now the mainstream model.

Several people continued to search and survey the factory area.

After a while, news came from the city:

"Dumbhand has been missing for several months. Legend has it that he was killed." Cui Qishan took the call and said helplessly to Jiang Yuan: "The few younger brothers who were hanging out with him also ran away."
