Without testing Zhang Yan with words again, Wang Zhaokai scooped up some water and took two sips.

But he did not leave the room, but looked around.

The room is about 40 to 50 square meters, and the stove is right after the entrance.

There is also a small boiler next to it.

"By the way, my phone is running out of battery. Do you have this charger at home? Let me use it so I can charge my phone."

Not finding anything unusual, Wang Zhaokai made up an excuse and went straight into the master bedroom.

Zhang Yan was shocked, but it was not easy to stop him, so she quickly said, "Captain Wang, the phones we use are ordinary phones. I don't know if the charging port can be matched with yours. How about I go to someone else's house and ask for you?"

As he said this, he was about to walk out, which meant that since he was leaving, it would be embarrassing for you to stay in our house alone.

But Wang Zhaokai ignored the other party. After entering the master bedroom, he began to observe carefully.

The master bedroom was not clean and was rather messy.

However, the ground looked as if it had been cleaned, and some of the stained areas looked different from other areas.

kindness?
Soon, Wang Zhaokai made some discoveries.

Zhang Yan's home has a boiler, so heating pipes are arranged along the anti-inflammatory circle.

Although the floor had been cleaned, there were still a lot of stains in the gap between the heating pipe and the kang wall, and Wang Zhaokai's attention was attracted by these stains.

brown.

Some of them were brown marks similar to dried blood, and some spots were discovered by Wang Zhaokai.

Of course, these spots are relatively small, and the color seems to be no different from ordinary putty stains.

Although Wang Zhaokai is not an on-site investigating criminal policeman, he has been working on the front line for many years and is very familiar with some of the blood spray traces at the scene.

Although there was still some uncertainty, the traces on the collision points still made Wang Chaokai suspicious.

Because Wang Zhaokai had just walked straight into the master bedroom, Zhang Yan had no way to leave directly, so she followed him in.

Seeing that Wang Zhaokai's eyes were searching the ground, Zhang Yan's heart suddenly rose to her throat.

"Captain Wang," Zhang Yan stepped forward, blocking Wang Zhaokai's sight, and took the phone's charging cable from the kang and handed it to him, "Look, this is my phone's charging cable. Can it be matched with your phone's charging port?"

Charging cable?
Wang Zhenhai glanced at Zhang Yan without even looking at the charging cable in his hand, and left the master bedroom directly.

When he got outside, Wang Zhaokai didn't stop at all. After he walked out of the yard, he immediately called Lu Chuan.

"Director Lu, I just found a little blood stain on the floor of Zhang Yan's master bedroom. Was there any spray-like blood stain left last time? Would you like to come and take a look?"

Take a look?
After Lu Chuan received the call, he thought that since Wang Zhaokai called him, it meant that the discovery was almost certain.

Three minutes later, more than a dozen criminal police officers arrived at Zhang Yan's home.

At this moment, Zhang Yan has been controlled.

"Captain Wang...what are you doing?"

When Li Da Kui saw his daughter-in-law being arrested, he became anxious and panicked.

He couldn't understand why the police arrested his daughter-in-law.

People in the village saw many criminal police rushing to Zhang Hai's house, and many people followed to watch the fun.

However, Lu Chuan was already squatting on the ground, carefully examining these dot-like marks.

Compared with Wang Zhaokai, the ambiguous confirmation is different. Just one look at Lu Chuan and he knew that these were definitely some dot-shaped traces formed after the human body's blood was sprayed.

And it doesn't last long.

At the same time, Lu Chuan conducted a detailed inspection of the entire master bedroom and found that except for the corners, there were large patches of dried blood on the kang when he lifted the mat.

After opening the cupboard, Lu Chuan really found bloody bedding and pillows inside.

It is obvious that the bold speculation made by the police in the early stage was not wrong. Zhang Yan was actually the murderer who hurt Li Xiaofeng.

Next, they searched the three rooms of Zhang Yan's house carefully, and found a blood-stained hammer and a kitchen knife with a bent blade in the corner of a warehouse.

In addition, blood-stained clothes were found in a plastic bag in the corner.

Obviously, Zhang Yan has not had time to deal with these things.

"Take the people back and seal off the scene immediately!"

A lot of couples never imagined that the person who killed their son was their daughter-in-law Zhang Yaner.

"It's impossible, it's impossible, how is this possible?"

When the two elderly people were taken into the police car in Zhangye, they didn't believe it was true.

After all, it was Zhang Yan who called to inform them about her son's disappearance.

Moreover, over the past few days, Zhang Yan has been following them and searching diligently.

Besides, to be honest, Zhang Yan is a really good daughter-in-law.

When she got married, she didn't ask for much dowry, and she has been very well behaved after marrying her son Li Xiaofeng.

The two old people knew very well what kind of person their son was, but Zhang Yan'er had been in charge of everything inside and outside the family over the years. If it weren't for Zhang Yan'er, it's hard to say what this family would be like, and it might have broken up long ago.

This is also the most important reason why the two elderly people did everything they could to win back their daughter-in-law after Zhang Yan and Li Xiaofeng divorced half a year ago.

But why?

It turned out to be his own daughter-in-law who killed his own son.

Although the fact that Zhang Yan was the murderer of Li Xiaofeng has not been confirmed by the police, she has already been taken away into the police car and everyone in the village has witnessed it with their own eyes.

In less than an hour or two, the news spread throughout the village.

On the Criminal Police Brigade side, Lu Chuan and Wang Zhaokai have escorted the criminal suspect Zhang Yan back to the Criminal Police Brigade for further interrogation.

There are two on-site detectives conducting the final investigation at the crime scene.

Zhang Datao, a police officer from the town's police station, personally led a team to seal off the entire scene and set up cordons around the area.

In addition, Zhang Datao also sent people to guard the crime scene for the next two days.

Lu Chuan immediately called Chen Weiguo to report the relevant situation.

Zhang Yan didn't say anything when she was taken away. She looked a little relieved, but the rest of her expression was just crying silently.

However, he did not resist when the police took him away, so it was obvious that Zhang Yan was the murderer.

The case can be considered solved so far. The follow-up is interrogation, identification of the scene, the cause of the case, and other detailed investigations.

Chen Jiang was in charge of the interrogation in the interrogation room, and Zhang Yan did not resist.

She quickly confessed the crime of killing her husband. (End of this chapter)
