In less than a minute, everyone gathered in the machinery factory area, and Chen Yi looked at the shocking luminol reaction in front of him, his face was gloomy as water, like a dark cloudy sky.

As time passed, the glow of the luminol reaction was fading, as if to signal that a clue was about to disappear.

However, although the chemistry will disappear, the facts will always be there, and the truth behind them can never be erased.

Everyone looked at the feed grinder in front of them, the product of industrialization, which was supposed to bring convenience to people, has now become a tool for murderers to cover up their crimes.

A corpse, once ravaged inside the shredder, reduced to shards under the cold machine.

This is a trampling on the law, but also a trampling on human nature.

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

To investigate the case, let the evidence speak, try to extract DNA from the shredder, and then determine Fu Rongrong's identity through DNA paternity testing.

If it is really Fu Rongrong, then Song Lishun will be detained.

He is the biggest suspect.

Chen Yi walked out of the factory and looked left and right, the pigsty was not far away.

Xu Wenbing and others hurriedly followed.

When he came to the pigsty, Chen Yi pushed open the door, and the imaginary mess did not appear, but a clean and tidy environment.

Disinfectant mats and handwashing facilities are available at the door to ensure that everyone entering the farm goes through strict disinfection procedures to reduce the risk of virus transmission.

Along the aisle, Chen Yi walked slowly, and there was plenty of space on the left and right sides, so that the breeding pigs had enough range of movement.

Sensing the movement, the pigs were frightened and fled into the distance with a clattering sound.

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

The carcasses processed by the feed grinder are mixed with pig food, and these pigs will eat very vigorously, and there will be no residue left.

It is indeed a good way to destroy the corpses.

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

The few people behind him were silent, they knew that Chen Yi was not asking questions, but sighing.

This is criminal investigation, and the truth is often hidden under the nose, waiting for investigators to find out.

It is too normal and indispensable for a farm to have a feed grinder, and it is not suspicious at all.

Improve feed utilization, improve production efficiency, improve feed taste, reduce energy consumption and environmental pollution...... These are the advantages of having a feed grinder on the farm.

Therefore, the appearance of a grinder in the farm is not abrupt at all.

Who would have thought that it would become a tool for destroying corpses, and it was when Fu Rongrong was "alive".

"Captain Xu."

Xu Wenbing stepped forward: "Chen Zhi." ”

Chen Yi: "After determining that Fu Rongrong was killed, immediately control Song Lishun and take him to the county bureau, without considering his physical condition, he can have the strength to kill seven or even eight people, he is in good health." ”

Xu Wenbing ordered: "Yes!" Chen Zhi! ”

Although the result has not yet been determined, everyone knows that this is the greatest possibility, and only authoritative evidence is lacking.

Fang Shuyu soon arrived, and led people to carefully survey the feed grinder, hoping to find biological tissues that could extract DNA.

External searches continue.

When the time came in the evening, all the investigation work was over, and Fang Shuyu extracted hair and biological tissue in the shredder to ask Chen Yi's opinion.

The Pingxian County Bureau does not have the equipment to do DNA identification, and it needs to be sent to a higher department.

Chen Yi ordered that the samples be sent to Yangcheng overnight, and there was no need to bother to contact Fu Rongrong's parents, Wang Guigui was there.

As long as the specimen and Wang Guigui are determined to be mother-son relationships, then the corpse that once appeared in the crusher is Fu Rongrong, which is very simple.

"Shuyu, you go back first, the work here should be over, if you need to call you again, this case may not be over when." Chen Yi said to Fang Shuyu.

Finding Fu Rongrong does not mean that you can solve the case, and it is a big problem to break Song Lishun.

If we don't mention the others, it is difficult to speculate on the motives, which is incredible.

"Okay." Fang Shuyu didn't refuse, she knew that staying wouldn't help much.

……

Everyone was busy all day without eating, hungry chest against back dizzy, tonight Xu Wenbing treated, almost booked a night stall to eat barbecue and shabu-shabu, which can be regarded as a major breakthrough in the celebration of the case.

When the new in the prefectural bureau came, too.

The barbecue in Pingxian County is still very famous in Yangcheng, so of course you have to try it if you have the opportunity.

"One bottle of beer per person, not allowed to drink too much, just say that I allowed it." Chen Yi waved his hand and threw away the prohibition.

If you eat barbecue and don't drink beer, then you still eat a fart, it's better to go home and nibble on steamed buns.

Everyone was overjoyed, and there was a detachment leader who carried them around without hesitation, shouting to carry beer.

The police are also human beings and need to decompress, and the most suitable way for them to decompress is to smoke and drink, and there are no conditions for the rest.

Syllable!

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

The case is not over yet, this supper is not a celebration banquet, but a meeting in disguise.

Chen Yi raised his head and took a drink, feeling refreshed and his mind a lot clearer.

Today is indeed very tired and hungry, but the hard work has not been in vain, and there has been a breakthrough in the investigation.

The hospital has strengthened its guards, keeping an eye on Song Lishun twenty-four hours a day, as long as he dares to leave secretly halfway, he will be immediately knocked down.

"What a real evil sect, what is Song Lishun's motive? I didn't even let go of my son, and I was crazy. ”

It was Xu Wenbing who spoke.

He didn't mention Fu Rongrong, if Fu Rongrong died, it could only prove that Song Lishun was suspected of poisoning and killing seven people, but it could not prove that he killed Fu Rongrong.

Chen Yi poured a beer and looked at Shi Xin: "What do you think?" ”

When Xin was eating boiled peanuts, he opened his mouth while chewing: "Killing my son is one thing, killing someone just after a kidney transplant, on the other hand, no matter how you look at it, Song Lishun's motives must be very strong, so strong that he doesn't hesitate." ”

Xu Wenbing answered: "Yes, Song Lishun is also a big disaster, he 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 shortly after surgery? To kill.

Who organized that dinner? It's himself.

Everything is unreasonable, everything becomes reasonable, and now there is only an incomprehensible motive, and the only doubt.

If it weren't for this suspicion, Song Lishun would not have been able to lie comfortably in the hospital at this moment, he would have been detained and summoned a long time ago, and he didn't have to wait for the DNA test results to come out.

There are cases of killing fathers, and killing sons is very rare.

The so-called mother's worries and mothers' worries, and mothers don't worry about their children, is a kind of irony of the relationship between parents and children.

Parents are givers, children are takers, and emotionally asymmetrical.

Chen Yi: "In this case, it is estimated that Wang Precious cannot be left behind." ”

Several people looked at it, and when Xin said, "You mean, it has something to do with Wang Guigui?" ”

Chen Yi picked up a bunch of mutton and looked at it, and said in his mouth: "The distance is too close in time, I just took away Wang's precious kidney, Fu Rongrong is missing, and the seven members of the Song family are poisoned and died, is there no connection here?" What a coincidence. ”

Shi Xin nodded: "It's a bit of a coincidence, but where will the point of connection be?" He was looking for Wang Guigui just to exchange his kidney for his life, as if it had nothing to do with Heping County. ”

Chen Yi stroked the mutton skewers: "We brought Song Lishun into the state of committing the crime, and now the DNA identification results have not come out, first of all, we assume that the body in the shredder is Fu Rongrong, and then assume that she was killed by Song Lishun." ”

"Based on this assumption, Song Lishun was discharged from the hospital on the fifth day after the kidney transplant and killed Fu Rongrong, which is too anxious, right?"

"It's better to say it's in a hurry, but it's better to say that you can't wait, why can't you wait? I think it's anger. ”

"He was so angry, he wanted to kill Fu Rongrong immediately, but his body didn't allow it, and when he felt that he had recovered well on the fifth day, he could move, so he immediately left the hospital and killed Fu Rongrong."

The word anger was raised, and the captains present were thoughtful.

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

But...... It doesn't have to be anger, either.

When Xin put forward another judgment: "It's certain that you are in a hurry, and there is also a possibility, Fu Rongrong needs to die as soon as possible, so that Song Lishun can feel at ease and achieve the purpose he wants in his heart." ”

Chen Yi shook his head: "This possibility is extremely low, Fu Rongrong is dependent on Song Lishun, everything is under Song Lishun's control, what is he not at ease?" The only variable in the near future is Wang Guigui, Song Lishun immediately launched a murder plan after taking Wang Guigui's kidney, we want to try to connect the two. ”

When the new silence begins to eat skewers.

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

The smoke rose, and Chen Yi analyzed it from the beginning.

First, Song Lishun found Wang Guigui, and the operation was successful after taking away the kidney, and then on the fifth day, when he had not fully recovered, he immediately left the hospital to deal with Rongrong.

In a hurry, very anxious.

Angry, very angry.

What will trigger Song Lishun's anger points?

What can involve Wang Guigui?

Could it be......

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

The closer the relatives, the higher the success rate of matching, and if it is an immediate family, the success rate can reach more than 90%.

Regardless of coincidence, Wang Guigui is Song Lishun's relative, yes, but not necessarily a son, right?

"I said, is it possible that Fu Rongrong cheated, Wang Guigui is not Song Lishun's son?" Chen Yi looked up.

Everyone pauses as they eat skewers and turns their heads in unison.

Shi Xin immediately spoke: "No, didn't Wang Guigui say it, kidney matching and paternity testing have been done." ”

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

When new: "Okay. ”

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

"Hello? When am I new ......"

"Just go in and ask now, don't hang up the phone, I'll wait."

After being quiet for a while, when Xin got feedback, the phone hung up, and he looked at Chen Yi: "Wang Guigui has not seen the DNA paternity test report, it was Song Lishun who told him...... No, if the paternity test results are not biological, how can the match be so coincidentally successful, and he also bought a house and gave money. ”

Chen Yi didn't speak, picked up his mobile phone and looked at the success rate of relatives matching, and then said to Xu Wenbing: "Tell the forensic doctor of the county bureau to extract the DNA of Song Lishun and all the men in the seven deceased and send them to Yangcheng, and I will let the people of the detachment do DNA paternity tests one by one." ”

Xu Wenbing's reaction was a little slower: "Huh?? Oooh...... Good. ”

When did you understand it newly: "Do you suspect Fu Rongrong of cheating on the Song family?" ”

Chen Yi: "DNA paternity test is compared to DNA sequence, Song Lishun is followed by a doctor, he can read the difference between parent-child and parent-child, a high degree of kinship, but not parent-child. ”

"In addition, the probability of a kidney match between relatives is also very high, which can explain why the non-biological but coincidental match is so successful."

"It's not a son, it's a relative, if Song Lishun knows about it, wouldn't he be crazy."

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

The eyes of everyone present widened, this ...... It's a bit of a mess.

Wang Guigui should not be Song Pingquan's son!

When Xin felt that his three views were impacted, he raised his hands: "Wait, wait, wait!" Let me take a look. ”

"Fu Rongrong was twenty-five years old, Song Pingquan was thirty years old, and Song Lishun was fifty-three years old...... Well, I'll admit it's quite likely. ”

On the other side, Xu Wenbing scratched his head, Song Lishun said in the Song family that he has extremely high authority, which is related to a man's self-esteem and a man's face, if it is true, the motive seems to be ...... Start with reason.

"That'...... What about Song Liguo and Song Linan? What does it have to do with them? Xu Wenbing raised new questions.

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

Speculation is speculation, and facts are facts.

Now we need to wait for the facts.
