Type O blood.

Among all the people involved in this case, Chen Yan has only contacted one.

Qin Ru!

Yes, it is Zhang Runsheng's beautiful daughter-in-law.

In the file Wang Gang gave Chen Yan, there is a brief introduction to Qin Ru.

Her blood type is type O blood.

But, how is this possible?

Is Qin Ru the murderer?

Chen Yan recalled the scene when he first met Qin Ru the day before yesterday.

This woman is like a spring in a mountain, her big eyes are black and transparent, without any impurities.

In her, Chen Yan felt the simplicity and kindness of rural people.

How could such a woman be the murderer?

And that terrifying child...

Moreover, judging from the evidence found on the scene, Qin Ru doesn't look like the murderer.

According to the analysis of Qiao Shouhe's corpse, he had suffered a heavy blow on the back of his head, and the weapon was the iron clamp.

But this is not a fatal injury.

There was a scratch on Qiao Shouhe's fourth rib, which indicated that the sharp knife had penetrated Qiao Shouhe's body deeply.

This knife is the ultimate fatal injury.

And Qin Ru, a woman, can do all this?

You know, Qiao Shouhe was 25 years old at the time, which was the best physical condition.

Even if he drank half a pound of white wine, it was not something Qin Ru could easily kill.

However, from the location where Qiao Shouhe buried his body, it is only about one thousand meters away from Zhang Songlin's greenhouse.

In this case, is it possible that Zhang Songlin and his family killed Qiao Shouhe together?

It was Qin Ru who was injured by a sharp knife in the Bo Dou, so she left blood on the sharp knife?

"Chaoyang," Chen Yan picked up the phone and called Zhang Chaoyang: "Check the health centers and hospitals near Xinjian Village."

"In the early morning or daytime of May 4, five years ago, were there any medical records of Qin Ru?"

Five years have passed, and some blood information can still be collected from the sharp knife, which proves that the sharp knife must have a lot of blood stains at that time.

So, if it was Qin Ru, it should be a relatively big wound.

In this case, you will likely seek medical treatment.

Then, finding this medical record is a breakthrough!

An hour later, Wang Gang's investigation of the ring had not returned yet, and good news came from Zhang Chaoyang.

"Captain Chen!" Zhang Chaoyang did not return to the second team of detectives, but called Chen Yan as soon as possible after finding the results: "Checked!"

"I'll send the registration records and medication records of that year to your mobile phone."

A moment later, Chen Yan’s WeChat prompt sounded.

They are three photos.

The first one is a photo of registration information.

Five years ago, on the morning of May 4, Qin Ru registered in the emergency department at Lingshui Town Hospital.

The second one is Qin Ru's diagnosis.

The right hand tool is scratched, bones are seen, disinfected and sutured...

The third one is the drug single bottom couplet, anti-inflammatory drugs, tetanus...

On the morning of May 4th, it was 6:34!

"Summon Zhang Songlin immediately, Zhang Runsheng and his son, and Zhang Runsheng's wife Qin Ru!"

The link of evidence that confirms Chen Yan’s reasoning is already conclusive, and the rest is to find motivation.

Qin Ru must be present at the scene of Qiao Shouhe's death.

However, can Qin Ru alone complete the murder, dismantle the corpse, and dig another three meters deep pit to bury it?

impossible.

So, she must have accomplices.

Zhang Songlin and his son, as the reporter, are suspicious.

In less than an hour, Chen Yan met Zhang Songlin in the interrogation room.

I met Zhang Songlin again. Although it was only a day later, Chen Yan felt that he was a little older.

Although there were many wrinkles on his face, Zhang Songlin's eyes were shiny and he smiled very kindly.

But today, although Zhang Songlin still smiled kindly, the light in his eyes became less.

"Hello, Officer Chen, we're meeting again..."

Zhang Songlin took the initiative to say hello to Chen Yan.

"Zhang Songlin, come to you today..."

"Officer Chen," Zhang Songlin interrupted Chen Yan's words, still smiling: "I know why."

"The day before yesterday, you dug a hole in the low woods, and I knew that you guys would find me sooner or later..."

To Chen Yan's surprise, Zhang Songlin did not hide anything and explained it clearly.

“That night, it was very hot…”

Zhang Songlin's memory is very clear and no details are left out.

"Runsheng and Xiaoru just got married not long ago, and they didn't have children at that time."

"In May, we planted some off-season vegetables and fruits in the greenhouse."

"Every night, you must adjust the intensity of the light exposure."

According to Zhang Songlin's explanation, that night, Zhang Songlin's family of three prepared to rest after adjusting the lights of the two greenhouses.

Because the weather is hot, I sweat a lot while doing farm work.

Zhang Runsheng built a simple bathing shed just outside the greenhouse.

"After finishing work, Xiaoru went to take a shower..."

"Runsheng and I were outside Dapeng and drank some wine..."

Zhang Songlin smiled, but his smile was a little bitter: "We rural people work during the day and don't drink some wine at night. They are sore all over and can't sleep at all."

"How could I think it was just less than a drink... something happened..."

That night, Zhang Songlin and Zhang Runsheng were drinking, but they heard a life-saving scream from where Qin Ru was taking a bath!

"I didn't think much at that time, Runsheng picked up the iron pliers beside him and rushed over."

"I also picked up the sharp knife that cuts meat beside me and ran over..."

As a result, with the moonlight, the two saw a vengeful scene.

The bathing shed had already collapsed.

Qin Ru was being pressed to the ground by a black shadow.

"At that time, the black shadow was pinching Xiaoru's neck and was about to do something beastly."

Zhang Songlin gritted his teeth, and his eyes were full of resentment even now: "The iron pliers in Runsheng's hand were thrown out at once and hit the back of the black shadow's head."

"The man was in pain. When he got up and saw that Runsheng and I were stunned."

"It's Qiao Shouhe, the captain of our Xinjian Village Team!"

"After he got up, he touched the back of his head and slapped Runsheng in the face."

"I also said that it was Qin Ru's blessing that he fell in love with Qin Ru. We asked us to promise Xiao Ru to accompany him once, otherwise his father would withdraw the greenhouse we contracted."

Even in the past five years, even though Qiao Shouhe is dead.

However, when Zhang Songlin talked about the incident at that time, his veins still burst out.

"He is a beast! What do you think of our Lao Zhang family?"

"That bastard, I thought we would agree. After saying that, he actually pulled Xiaoru who fell to the ground and was about to walk into the greenhouse."

"He also said that he had made a mistake and was happy today, don't mess with him..."

"Runsheng couldn't let Qiao Shouhe take Xiaoru away? He just pulled Qiao Shouhe up. I went forward, but the result was..."
