Detective: Open your eyes, I am handcuffed in the interrogation room

In less than a minute, everyone gathered in the machinery factory area. Chen Yi looked at the shocking Luminol reaction in front of him, his face as gloomy as water, like a sky covered with dark clouds.

At this moment, as time goes by, the light emitted by the luminol reaction is gradually dimming, as if it indicates that a certain clue is about to disappear.

However, although the chemical reaction will disappear, the facts will always exist and the truth behind them can never be erased.

Everyone looked at the feed grinder in front of them. The product of industrialization originally brought convenience to people, but now it has become a tool for murderers to cover up their crimes.

A corpse had been ravaged in the crusher and turned into fragments under the cold machine.

This is a violation of the law and a violation of human nature.

"Call Fang Shuyu and bring someone over." After a moment of silence, Chen Yi's voice sounded.

In the investigation, the evidence must speak for itself. DNA was extracted from the crusher, and Fu Rongrong's identity was determined through a DNA paternity test.

If it was really Fu Rongrong, then Song Lishun would have to be summoned.

He is the biggest suspect.

Chen Yi walked out of the factory and looked around. The pig pen was not far away.

Xu Wenbing and others quickly followed.

When he came to the pig pen, Chen Yi opened the door. The mess he imagined did not appear, but a clean and tidy environment.

Disinfection mats and hand-washing facilities are provided at the entrance to ensure that everyone entering the pig farm must undergo strict disinfection procedures to reduce the risk of virus transmission.

Along the aisle, Chen Yi walked slowly. There were spacious spaces on the left and right sides, allowing the pigs to have sufficient range of activities.

Upon noticing the movement, the domestic pigs were frightened and fled in the distance with the sound of squeaking.

Domestic pigs are omnivores and eat anything, including grains, vegetables, fruits, nuts and even some small animals.

The carcasses processed by the feed grinder are mixed in the pig food. The pigs will eat very enthusiastically and no residue will be left.

It is indeed a good way to destroy corpses and eliminate traces.

While walking, Chen Yi said: "We saw the feed grinder a few days ago, but we didn't think about it. In fact, the fact is very simple, right?"

Several people behind him were silent. They knew that Chen Yi was not asking a question, but was expressing emotion.

This is criminal investigation. The truth is often hidden right under the nose, waiting for investigators to discover.

It is normal, indispensable and not suspicious at all to have a feed grinder in a breeding farm.

Improve feed utilization, improve production efficiency, improve feed taste, reduce energy consumption and environmental pollution... These are the advantages of equipping farms with feed grinders.

Therefore, the presence of a crusher in a breeding farm is not unexpected at all.

Who could have expected that it would become a tool for destroying corpses and eradicating traces, and that was while Fu Rongrong was "alive".

"Captain Xu."

Xu Wenbing stepped forward: "Chen Zhi."

Chen Yi: "After confirming that Fu Rongrong was killed, immediately control Song Lishun and take him to the county bureau. There is no need to consider his physical condition. He has the strength to kill seven or even eight people. He is in very good health."

Xu Wenbing took the order: "Yes! Chen Zhi!"

Although the result has not yet been determined, everyone knows that this is the most likely possibility, and it only lacks authoritative evidence.

Fang Shuyu arrived soon and led people to carefully inspect the feed grinder, hoping to find biological tissue from which DNA could be extracted.

The search outside continues.

At night, all the investigation work was completed. Fang Shuyu extracted hair and biological tissue in the crusher and asked Chen Yi for his opinion.

The Pingxian County Bureau does not have the equipment to do DNA testing and needs to send it to the higher-level department.

Chen Yi ordered that the inspection materials be sent to Yangcheng overnight. There was no need to bother contacting Fu Rongrong's parents. Wang Guogui was right there.

As long as the examination materials and Wang Baogui are confirmed to be mother and son, then the body that once appeared in the crusher is Fu Rongrong. It's very simple.

"Shuyu, please go back first. The work here should be over. If necessary, I will call you again. This case may not be over when." Chen Yi said to Fang Shuyu.

Finding Fu Rongrong does not mean that the case can be solved. Breaking Song Lishun is a big problem.

Putting aside everything else, the motive is difficult to guess and is mind-boggling.

"Okay." Fang Shuyu did not refuse. She knew that staying would not help much.

…

Everyone had been busy all day without eating, and was so hungry that their chests were pressed against their backs and they were dizzy. Xu Wenbing treated him to a treat tonight and almost reserved a night stall for barbecue and tripe-shabu-shabu, which could be regarded as a celebration of a major breakthrough in the case.

When did Xin also come to the county bureau?

The barbecue in Pingxian County is still very famous in Yangcheng. Of course you must try it if you have the chance.

"One person has one beer, and you are not allowed to drink too much. Just say it is allowed by me." Chen Yi waved away the alcohol prohibition order.

If you don’t drink beer while eating barbecue, you’re still eating nothing. You might as well go home and eat steamed buns.

Everyone was happy, and a detachment leader led them to move the beer without hesitation at all.

The police are also human beings who need to relieve stress. The most suitable way for them to relieve stress is tobacco and alcohol. There are no other conditions.

Snapped!

At Chen Yi's table, Xu Wenbing opened a beer and handed it to him. It was impossible to avoid the case in our chat tonight.

The case is not over yet. This late-night dinner is not a celebration banquet, but a meeting in disguise.

Chen Yi raised his head and drank a drink. He felt comfortable all over and his mind became much clearer.

I am indeed very tired and hungry today, but my hard work has paid off and the investigation has made a breakthrough.

Guards have been strengthened at the hospital, keeping an eye on Song Lishun 24 hours a day. If he dares to leave secretly midway, he will be killed immediately.

"It's really evil. What's Song Lishun's motive? He doesn't even let his son go. He's so crazy."

The speaker was Xu Wenbing.

He did not mention Fu Rongrong. If Fu Rongrong died, it would only prove that Song Lishun was suspected of killing seven people with poison, but it could not prove that he killed Fu Rongrong.

Chen Yi poured the beer and looked at He Xin: "What do you think, Lao He?"

He Xin was eating boiled peanuts and said while chewing: "Killing your son is one thing, killing someone just after a kidney transplant is another thing. No matter how you look at it, Song Lishun's motive must be very strong, so strong that he doesn't even hesitantly."

Xu Wenbing answered: "Yes, Song Lishun survived the catastrophe and can enjoy his old age in peace. Why did he do such a thing?"

When Song Lishun was set as the murderer, all doubts disappeared, all coincidences became inevitable, and all far-fetched points became no longer far-fetched.

Why was he discharged from the hospital soon after the operation? To kill people.

Who organized that dinner? Just himself.

Everything that was unreasonable has become reasonable, and now only the unfathomable motive remains, which is also the only doubt.

If it weren't for this suspicion, Song Lishun would not be lying comfortably in the hospital at this moment. He would have been detained long ago without waiting for the results of the DNA test.

There are cases of patricide and killing of sons, which are very rare.

The saying that when a child travels a thousand miles, the mother is worried, but when a mother travels a thousand miles, the child is not worried, it is a satire on the relationship between parents and children.

Parents are givers and children are takers. They are not emotionally equal.

Chen Yi: "This case probably cannot leave out Wang Baogui."

Several people looked over and asked, "You mean, you have something to do with Wang Baogui?"

Chen Yi picked up a bunch of mutton and looked at it, and said: "The time is too close. Wang Baogui's kidney was just taken away, Fu Rongrong disappeared, and seven members of the Song family were poisoned and died. Isn't there any connection? Tai What a coincidence."

Ji Xin nodded: "It's a bit of a coincidence, but where is the point of contact? He only came to Wang Baobao for a kidney transplant to survive. It seems that it has nothing to do with Heping County."

Chen Yi licked the mutton skewers: "We have brought Song Lishun into the crime scene. The DNA identification results have not yet come out. First, we assume that the body in the crusher is Fu Rongrong, and then we assume that Song Lishun killed her."

"Based on this assumption, Song Lishun was discharged from the hospital on the fifth day after the kidney transplant operation and killed Fu Rongrong. This was too hasty, right?"

"It's better to say I'm anxious, but it's better to say I can't wait. Why can't I wait? I think it's anger."

"He was so angry that he wanted to kill Fu Rongrong right away, but his body did not allow it. On the fifth day, when he felt that he had recovered well and could move around, he immediately left the hospital and killed Fu Rongrong."

When the word "angry" was mentioned, the captains present were thoughtful.

Thinking about it carefully, he was indeed in a hurry. He had to kill Fu Rongrong as quickly as possible.

But...it doesn't have to be anger.

He Xin made another judgment: "It is certain to be anxious. There is another possibility. Fu Rongrong needs to die as soon as possible, so that Song Lishun can feel at ease and achieve what he wants in his heart."

Chen Yi shook his head: "This possibility is extremely low. Fu Rongrong relies on Song Lishun to exist, and everything is under Song Lishun's control. Why should he feel uneasy? The only variable in the near future is Wang Baogui. Song Lishun immediately took away Wang Baogui's kidney. A murder plan has been launched, and we have to try to connect the two."

When the new silence, start eating skewers.

Chen Yi drank another glass of beer. After eating for a while, he felt full, so he picked up the cigarette case and took out a cigarette.

Smoke rose, and Chen Yi started his analysis from the beginning.

First, Song Lishun found Wang Baobao, took away the kidney and the operation was successful, and then on the fifth day before he fully recovered, he immediately left the hospital to attack Rongrong.

Anxious, very anxious.

Angry, very angry.

What would trigger Song Lishun's anger?

What could involve Wang Guogui?

Could it be...

Thinking of a possibility, Chen Yi took out his mobile phone and searched. The search content was the success rate of kidney matching between relatives.

The closer the relative is, the higher the success rate of matching. If they are direct relatives, the success rate can reach more than 90%.

Coincidence aside, it is true that Wang Baobao is a relative of Song Lishun, but he is not necessarily his son, right?

"I asked, is it possible that Fu Rongrong cheated on her, and that Wang Guogui is not Song Lishun's son?" Chen Yi raised his head.

Everyone stopped eating skewers and turned their heads.

He Xin immediately said, "No way. Didn't Wang Guogui say that he has done kidney matching and paternity testing?"

Chen Yi: "The match was successful, but he may not have seen the DNA paternity test report with his own eyes, so he called Yangcheng immediately to ask."

When is new: "Okay."

He took out a tissue and wiped his hands, then picked up his cell phone and dialed the number in Yangcheng.

"Hello? When did I new..."

"Go in and ask now. Don't hang up the phone. I'll be waiting."

After a long silence, Ji Xin received feedback. He hung up the phone and looked at Chen Yi: "Wang Guobao has never seen the DNA paternity test report. Song Lishun told him... That's not right. If the paternity test result is not a biological child, , how the matching was so successful by chance, and he even bought a house and paid for it."

Chen Yi didn't say anything. He picked up his phone and checked the success rate of relatives' matching. Then he said to Xu Wenbing: "Tell the forensic doctor at the county bureau to extract the DNA of Song Lishun and all the males from the seven deceased people and send it to Yangcheng. I will let them The people in the detachment conducted DNA paternity tests one by one."

Xu Wenbing's reaction was a little slow: "Huh?? Oh oh... OK."

When did I finally understand: "Do you suspect Fu Rongrong of cheating on the Song family?"

Chen Yi: "The DNA paternity test compares DNA sequences. Song Lishun is accompanied by a doctor. He can understand the difference between paternity and relatedness. A high degree of relatedness is not paternity."

"Furthermore, the probability of kidney matching between relatives is also very high, which can explain why unrelated people are so coincidentally matched."

"Not a son, but a relative. If Song Lishun knew about this, he would go crazy."

"Correspondingly, there are also signs of the motive for poisoning other people, such as his son."

Everyone present widened their eyes, this... was a bit messy.

Could it be that Wang Baobao is Song Pingquan’s son?

When Shi Xin felt that his outlook on life was being impacted, he raised his hands: "Wait a minute, wait a minute! Let me take a look."

"Fu Rongrong was twenty-five years old, Song Pingquan was thirty, and Song Lishun was fifty-three... Well, I admit that the probability of it happening is not small."

On the other side, Xu Wenbing scratched his head. Song Lishun said that Yibuer had extremely high authority in the Song family. It was related to a man's self-esteem and his face. If it was true, the motive seemed... to be reasonable.

"Then... where are Song Liguo and Song Linan? What does it have to do with them?" Xu Wenbing raised a new question.

Chen Yi drank all the wine in the bottle and said, "Don't think so far ahead. Let's wait for the result. If Fu Rongrong dies, it may not be Song Lishun who killed her."

Speculation is speculation, facts are facts.

Now we need to wait for the facts.
