Siheyuan: I, He Yuzhu, entered Changjin Lake at the beginning

Zhou Zheng:"No, how is this possible? She killed herself?

How did she do it?

The neighbors said she was stabbed in the back. When she was sent to the hospital, the knife was still in her back.

Still Yes, why did she hurt herself after killing her husband and his family?

It's not in line with common sense! It's not necessary?"

He Yuzhu:"Listen to my analysis!

The first doubt in this case is how the gangsters Entering the door.

Suppose someone comes to visit, no matter what time of day, a woman cannot open the door in the middle of the night, right?

And according to the etiquette in our country, even if it is a very familiar person, she must get dressed before opening the door in the middle of the night, right?

This is the first, and the second is to break into the house over the wall.

But this is not consistent with the traces at the scene. If someone entered my house at night on"187", why would they have to leave traces on the wall?

I am at Guo's house I looked around the exterior wall several times but couldn't find any traces of footprints, flying claws, or ladders....

Third, the door of Guo's house opened by itself from the inside without any damage.

Think about it, when you go to bed at night, is the door in your house tightly closed and bolted?

If an outsider wants to get in, how can it be possible without breaking the door bolt?

Therefore, it can only be an acquaintance who committed the crime. Considering the circumstances of the scene, the most likely person is the Guo family's daughter-in-law.

And what supports this is that there were no signs of a fight in the house.

Zhou Zheng:"Okay, even if what you say is right, what about committing suicide?"

How did she commit suicide?"

He Yuzhu:"I found a mark on the outer wall of the east wing of the Guo family. The shape is very much like the handle of a dagger, but this is the only one. The mark is very new. It should have been there in the past few days..

The height of the mark is basically the same as the height of the knife on the daughter-in-law of the Guo family, so my inference is that the daughter-in-law of the Guo family killed her husband and parents-in-law with a knife while her family was sleeping and resting for some reason. , faked the scene to create the illusion that someone was involved in a burglary or theft, and then seriously injured himself with a knife to evade our investigation. As a result, he accidentally killed himself......."

Zhou Zheng:"Where's the evidence? What you said is all your speculation. Although it makes sense, there is no evidence to support it!

Also, you said that the Guo family's daughter-in-law committed suicide, and there is that mark on the wall. I still don't know. Understand how she committed suicide......"

He Yuzhu:"Well, let me give you a sign and you will know."

Then, He Yuzhu took a pen from his pocket and walked to the wall and said:"This pen in my hand is a sharp knife. You see......"

I saw He Yuzhu holding the pen behind him with one end against the wall, and the other end aimed at the back of his heart, and then called Zhou Zheng to come over and check.

Zhou Zheng came over to take a look and said:"You mean, the woman put the handle of the knife against the wall and leaned back hard, so she would hurt herself!"

He Yuzhu:"Yes, this point is shown from the perspective of the wound of the deceased. It is consistent with the way the knife was inserted into the knife at a ninety-degree right angle.

This is because such a wound angle would never appear when she was escaping or after being subdued.

But unfortunately, she used too much force and the knife stabbed too hard. It got so deep that I finally played myself to death.

This time there was no evidence, and the case could only remain unsolved......."

Zhou Zheng:"But it's okay. At least it proves that there is no murderer and no one is free."......"

He Yuzhu:"Now the case is taken over by the superiors, report this thing......"

Zhou Zheng:"You don't have to worry about it. I'll call the bureau later to report your speculation and evidence. As for the consequences, we can't control it."

He Yuzhu:"Okay, please excuse me, Zhou Suo!"

Zhou Zheng:" What’s the trouble! (If you want to read exciting novels, go to Feilu Novel Network!)

I will retire in half a year. I don’t have much time left in the institute and there isn’t much I can do. I would like to make more contributions. You should!

But you really surprised me. You solved the unsolved case in just half a day......."

He Yuzhu:"You taught me well......"

Zhou Zheng:"Don't say that. I really haven't taught you anything in the past few months since you've been here. Okay, I've been busy for a long time. I heard that your kid didn't eat in the morning, so I quickly found a place to eat something to make up for it." Just rest your stomach. If you have nothing to do in the afternoon, go home and rest. Come here early tomorrow!"

He Yuzhu:"Yes!"

Afterwards, He Yuzhu left the police station and went home to rest....

After He Yuzhu left, Zhou Zheng picked up the phone on the table and called the bureau. On the phone, Zhou Zheng explained He Yuzhu's judgment and evidence, and gave the direction of the case, which bought a lot of time for closing the case and reduced the cost. The workload of the Municipal Bureau on this case was reduced.

After subsequent interviews and investigations by trace inspection experts from the Municipal Bureau, the incident was highly consistent with what He Yuzhu said.

Although I don’t know what the Guo family’s daughter-in-law’s motive was for committing the crime, this is the only way to close the case.[]

The Guo family has no living relatives, and the daughter-in-law came to Sijiu City in the past two years to look for relatives from other places. She failed to find relatives and spent all her money. There are no relatives in her hometown, so she finally married a nearby man. The resident of the Guo family.

After He Yuzhu knew this detailed information, he felt that the identity of the Guo family's daughter-in-law was very suspicious, but now that she was dead, there was no way to verify her true identity. He Yuzhu returned to the courtyard from the house, and first went to the old man in the backyard. Madam, after learning that the old lady had already had lunch, she went home and gave herself a bite to eat.

After padding my stomach, I took a change of clothes and went straight to the bathhouse near the compound.

I took a dip in the big pool, went to the bath master and rubbed it carefully before and after, dried my body, put on clothes and went home to sleep 1.0.

At half past four in the evening, not long after it got dark, He Yuzhu woke up from his sleep, checked the time, and got up to make dinner for his family.

The meal was just right. He Daqing entered the house carrying a net bag with two lunch boxes.

"Yo, you are at home today! Don’t you have a case to handle in the morning?

He Yuzhu:"It's done!" Although it was a murder case, it was later accepted by the superiors. We just helped survey the scene and visited and investigated. What happens next has nothing to do with us......."

He Daqing:"That's right! By the way, what's going on with this case?

Who's family was killed? For what reason?"

He Yuzhu:"All four members of the Guo family in Xiaoguan Hutong died and the whole family was wiped out.

As for the specifics, I Not sure......"......
