A rhetorical question caused the interrogating policeman to choke the next words in his throat. The two policemen glanced at each other, and the one on the left got up and went out.

He adjusted the earphones and whispered into the intercom: "Sister Fan, what should we do now? If there is no conclusive evidence to crush her to death, she will never admit it."

Fan Yu listened carefully to the voice in the earphones, her expression became more and more serious: "It looks like she came prepared, and her psychological quality is much better than ordinary people. Our people have already searched the factory, and I hope to find something. "

"First, you unintentionally disclose to her some news that the person in charge of Qiayuan has been arrested, and try to slowly break down her psychological defense - tell her that even if she doesn't tell, some people will tell her before her, then the commutation of the sentence will be easy. There's no more for her."

"It's not a good thing for her to stay in prison until the end of menopause at such a beautiful age."

In a short period of time, Ma Lin saw that the policeman had gone out for a long time and there was no movement, and there was probably nothing to do, so she became more confident in her heart-as long as she refused to admit it, no one could do anything to her.

A cigarette reached the filter within a few puffs, and Marlene casually pressed it out on the table.She suddenly became interested in handcuffs. Under the incandescent light, the handcuffs clearly reflected her own shadow, a thin face, and a bunch of bangs sticking together.

"Uncle policeman, do you have any questions? I only asked two questions, thank you." Ma Lin asked blankly.

Tobacco is like a tranquilizer for Marlene, as long as she smokes it, she will instantly change herself, and her behavior does not match her age.

"Do you still have cigarettes?" Ma Lin poked her head, and said, "Zhonghua is easier to smoke than inferior cigarettes."

The policeman on the right kept tapping the record book with his pen cap a little anxiously, turning a deaf ear to her words.

"Hey, do you have a cigarette?" Marlene got a little impatient, "Before I leave, don't you want to give me another cigarette——"

"Who said you can leave?" At this moment, the policeman on the left just opened the door and came in, cutting her off.

Marlene slightly raised her eyebrows, and tapped the round clock on the opposite white wall with her chin: "Uncle policeman, the maximum limit for detaining citizens without reason is 48 hours. More than four hours have passed now."

Ma Lin's arrogant behavior angered Fan Yu, and the male intern also interjected with a headset on: "How can a little girl know this kind of thing so well, she has heard it for 48 hours, I don't think I knew it when I was just in college..."

"Could it be..."

Fan Yu stared at Ma Lin's face on the monitor: "Her father Ma Yue should have been detained in this way and released many times, so she will know."

"Officer Fan, someone is looking for you." Someone knocked on the door and shouted.

Fan Yu let the other criminal police who took over the case continue to watch, and went to the hall first.

Qin Ruochu came to provide clues to the police with a few checklists. She told Fan Yu that there must be something wrong with the factory, and that the shipment was twelve hours late.

"Follow me to the scene."

Qin Ruochu was sitting in the co-pilot of the police car, with the red and blue lights flashing, and Fan Yu galloped all the way to the Qiayuan factory.

There were several police cars parked in front of the factory. After entering, Qin Ruochu saw that there were police officers holding evidence bags to extract evidence in each workshop. There was no one else at the scene except those in uniform.

"Xiao Zhou."

"Hey, Sister Fan is here." Xiao Zhou greeted her with a smile.

"Have you found anything? Ma Lin doesn't admit it, and we can't find any clues within 48 hours, so we have to let her go. If she escapes, it will be difficult to catch her." Fan Yu took the bag in his hand. Folder, look carefully.

"Officer Xiao Zhou." Qin Ruochu greeted, "I'm an employee of MAICU, and I've been in contact with the police to provide clues. Can you show me around? I'm afraid that acting on my own will break the rules."

"Hello, beauty." Xiao Zhou had just shaved his short hair, and couldn't help but blush when he saw the beauty. He touched the back of his neck and asked Fan Yu with his eyes.You must know that in the Weicheng Criminal Investigation Brigade, except for Fan Yu and another female police officer who was just pregnant and on vacation, all the others were male without exception.What's more, Fan Yu has been married for more than five years.

Fan Yu didn't know what Xiao Zhou was thinking, so he just let out a "huh".

Xiao Zhou gave her a pair of rubber gloves and began to walk her around.

"Officer Xiao Zhou, I want to go to Workshop 08." The reason why Qin Ruochu went here first was because the raw materials for the last batch of goods were processed in Workshop 8.As soon as she entered, she began to sniff against the wall, and Xiao Zhou felt a little embarrassed.

There was nothing ladylike in the behavior of this beauty.

"what happened?"

"I'm smelling aniline." Qin Ruochu said truthfully, she stretched out her hand to rub the plaster on the wall, put it in the palm of her hand and smelled it again.

"We also thought about it, but after testing, there is no aniline residue here." Xiao Zhou looked at the empty machine, "Even the dust has been tested."

"Is it just workshop No. 8?"

Xiao Zhou: "No, it's all workshops."

No aniline residue... how is that possible.

"Did it evaporate?"

"Theoretically, even if it evaporates, there will be residue." Xiao Zhou scratched his scalp, it was cold, his hair was bald, and his scalp was frozen stiff.

"If we can find evidence to prove the existence of aniline now, basically the relationship will be over."

"Can this remove the suspicion of our boss?" Qin Ruochu continued.

Xiao Zhou nodded: "Yes, but she may still bear part of the responsibility, but at least it has nothing to do with her."

Aniline is one of the raw materials for making dyes. Qiayuan’s dyes are usually purchased wholesale. If it wants to get industrial aniline from dye wholesalers, it is not difficult, let alone arouse suspicion.

"Is it possible that other chemicals were used in the treatment of aniline?" Qin Ruochu looked up the information: "Acidic substances are easily soluble in ethanol..."

"Beauty, we have thought of all these. The director of the testing room has considered all the chemicals that can react with aniline, but there is still nothing."

Then what went wrong... Qin Ruochu fell into deeper thinking.

"What are you talking about?" Fan Yu walked over.

"Officer Fan, is there heavy aniline residue on the clothes?" Qin Ruochu asked.

Fan Yu shook his head: "It's not very heavy, and they probably don't want to kill people. It's just that Gong Meixin is an exception. She is too sensitive to aniline and smells, and she got on her clothes without washing them. She also has respiratory diseases, so The reaction was extraordinary."

"The aniline adsorbed on the clothes is usually diluted and gasified, and then slowly smoked up. As for the smell afterward - it should be that they used some method to temporarily suppress the smell." Fan Yu added.

"Aniline is adsorbed on clothes...clothes...adsorbed..." Qin Ruochu closed her eyes, and a gleam of light flashed across her brain: "Absorb!"

"Huh?" Xiao Zhou turned to look at her.

Qin Ruochu's tone was a little excited: "Since aniline can be adsorbed on clothes, is there something that can completely absorb aniline, resulting in no trace of residue? Aniline does not disappear by chemical reaction, but by physical methods."

"That's right!" Xiao Zhou patted his thigh: "Why didn't I think of that!"

"We all think that the people in the factory are well versed in the reactions of chemicals, but we ignore that they may 'do the opposite', using this most laborious method, but can make all the chemicals that have appeared disappear without a trace No trace."

Fan Yu looked at Qin Ruochu with a look of surprise and appreciation: "It's usually activated carbon and rubber, Xiao Zhou, send someone to check Qiayuan's transaction records for the past three months, and if there are no public transactions, go and check the responsible ones. The private account transaction records of the person and the boss.”

"This kind of activated carbon and rubber are usually recycled after use, but they are used to absorb aniline. They are guilty of guilt and will definitely not send them for recycling. They can only-"

Qin Ruochu gritted his teeth and said, "Send it to the landfill."

Xiao Zhou had a headache again: "There are four landfills in Weicheng alone, and it is several days away from the 27th of the twelfth lunar month. Could it be buried deep?"

Fan Yu said: "They will definitely not be working during Chinese New Year. Let's take people to rush there now, maybe we can find clues. Let's move first."

The Weicheng Criminal Investigation Detachment dispatched more than 20 police officers to four different landfills in the suburbs. Qin Ruochu and Fan Yu went to the landfill in the south.

As soon as the car stopped, a strong rancid smell rushed straight to the top of his skull. Qin Ruochu retched in the car, and then pinched his nose tightly.Fan Yu took out two masks from the car and handed them to her: "Wear them stacked."

The garbage landfill on the south side of Weicheng covers an area of ​​27 hectares, and there are mountains of mixed garbage piled up everywhere.

The person in charge had already been notified by the police in advance to wait here. Fan Yu walked towards that person, and Qin Ruochu followed slowly. The broken fish bone and the apple skin seemed to be moving, Qin Ruochu got closer, and saw a few big white maggots squirming out from the bottom, Qin Ruochu immediately felt his stomach churn, and covered his mouth through the mask.

"It's there, okay. No need, I know where it is." Fan Yu beckoned, motioning for Qin Ruochu and other policemen to follow.

Soon, they came to another place piled up into a hill.

Here is no longer kitchen waste and wet garbage, some disgusting garbage mountains, but dry garbage, which is relatively less smelly.Fortunately, it is winter now, if it were summer, Qin Ruochu felt that she would be fainted by the smoke.

"Sister Fan, this is where the activated carbon, rubber, and discarded steel bars are buried."

Fan Yu nodded: "Check the unburied ones first, starting from the bottom."

Just as Qin Ruochu was about to sigh how such a large amount of work would be carried out, several forklifts entered her field of vision.

Fan Yu asked for some more manpower from the bureau, and simply called out all those who were free from the technical investigation, network investigation, and economic investigation detachments and could go out to work.

Four hours later, Fan Yu's cell phone started to vibrate.

"Sister Fan, activated carbon with residual aniline was detected in the landfill on the east side!"

"Officer Fan, rubber with residual aniline was detected in the landfill on the west side!"

……

"Old Fan!" Old Wang next door poked out a round head in the garbage dump: "Come here!"

"coming!"

When Qin Ruochu heard the commotion, she ran out of the car anxiously.

"There's something wrong. There's a pile here, and the ones buried in the innermost are all adsorbed aniline. Take a look at the photos sent by the testing center just now."

Fan Yu's frown finally relaxed a little, and the case had a breakthrough.

"Okay, put the evidence bag."

"Pile all these together in isolation first, it may be useful in the future." Fan Yu shouted.

The old Wang next door quit: "You are the only one who can call people. So many brothers were blowing the heater in the office, but you have all pulled them here to do the coolie!"

Fan Yu held up his mobile phone: "I'll record it for you again and play it for Ju Liao."

Chief Technical Investigator Wang had no choice but to shut up resentfully.

The author has something to say: This crop will end soon!
