Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

In the interrogation room, Zheng Gaoxue was so frightened by Wang Zhaokai that he broke into a cold sweat.

What can be determined from all the investigation results so far is that Zheng Gaoxue met Qin Weiwei himself in the afternoon of the incident.

The other two were lovers before, and the breakup was unpleasant.

Zheng Gaoxueben himself became addicted to gambling.

Also, when he was in school, he learned low-voltage technology.

The small black box found in Qin Weiwei's home distribution box was probably put in by him.

After the incident, he left Haizhou City that morning.

With so many clues intertwined, in Wang Zhaokai's view, Zheng Gaoxue was the suspect.

However, no matter how Wang Zhaokai tried, Zheng Gaoxue refused to admit that he killed Qin Weiwei.

"Officer...I really didn't kill her."

"Why did you lie about not killing her?"

"I'm a grown man...stealing my girlfriend's money...it's embarrassing to talk about it."

Wang Zhaokai...

"Do you know where this place is? This is the Criminal Police Brigade!"

"Disgraceful?
Thank you for thinking it through. "

Another office.

"Team Lu, if this Zheng Gaoxue is the murderer, he is most likely trying to make money."

"However, the valuables in the deceased's home were indeed not lost, and there are transfer records of the 20,000 yuan the other party said he borrowed from Qin Weiwei."

"Could he be the murderer?"

Whether he is the murderer or not is not a matter of guessing.

Although judging from the current clues, every one points to Zheng Gaoxue.

But Lu Chuan still wanted to verify it.

The murderer was at the scene, but not everything was left behind.

The four characters on the bathroom mirror are the most powerful identification clues.

"It doesn't look like it from the handwriting."

Lu Chuan has the handwriting identification and analysis ability rewarded by the system. He just asked Zheng Gaoxue to sign the form just to see if his handwriting matched the four words "Give me my life" left on the bathroom mirror.

"In this case, let Zheng Gaoxue copy this and bring it to me later."

The most rigorous aspect of handwriting identification and analysis is to compare the original characters, that is to say, let the other party write what kind of words you want to compare.

Although Lu Chuan just found that the signature on the other party's name did not match, in order to be more safe, he decided to compare it with the original characters.

However, if you directly ask the other party to write the words "give me my life back", if it is indeed the other party who did it, then he will definitely change the handwriting.

So Lu Chuan chose a text with these four words mixed in it.

This will lower the other party's wariness.

In addition, if the murderer writes these words, they will disappear within a short time.

If Lu Chuan hadn't observed carefully, he wouldn't have discovered it at all.

Wang Zhaokai and Zheng Gaoxue struggled for four hours, but still couldn't win.

"Holy shit, this guy is so difficult to deal with."

After leaving the interrogation room, Wang Zhaokai shook his head.

"Either this guy is really not a murderer, or he has an extremely strong psychological quality."

After four hours, faced with so much evidence, an ordinary person would have given up long ago.

"Okay, you rest for a while. Captain Lu asked me to take this in and let Zheng Gaoxue copy it."

Wang Zhaokai took a look...

"Notification?"

As a suspect, Zheng Gaoxue was required to sign a notice after being arrested and before being interrogated.

This is a necessary process.

“Isn’t this thing just a signature?”

Chen Jiang shook his head: "Captain Lu asked to compare his handwriting. Some of the words on it are the same as those on the bathroom mirror."

"Okay, you rest for a while, I'll go in."

"it is good."

Wang Zhaokai returned to his office, drank some water, and took a rest. Four hours later, my mouth was dry.

Chen Jiang's side went smoothly. In less than ten minutes, the copying was completed.

Lu Chuan's office.

After getting the notice copied by Zheng Gaoxue, Lu Chuan casually circled 4 words.

Give me back my life.

The result further verified the handwriting identification analysis Lu Chuan had just done.

"not him."

From the perspective of font identification analysis, even if the other party deliberately conceals the same font, some details will be exposed.

Coupled with the comparison of strokes in other fonts, Lu Chuan could confirm that the words on the bathroom mirror at the crime scene were not written by Zheng Gaoxue.

"The results of the autopsy showed that Qin Weiwei died of cerebral hemorrhage due to intense emotional changes caused by excessive fear."

"Judging from the situation at the scene, the person who wrote the font and the person who manipulated the distribution box of Qin Weiwei's home are most likely the murderer."

Regarding this judgment, there is actually a consensus within the criminal police brigade.

You can imagine that Qin Weiwei lives alone, but in the middle of the night, he sees 4 words on the bathroom mirror, "Death".

Then the lights in the room flickered.

This atmosphere is terrifying enough.

Of course, just these are probably not enough to scare people to death.

Therefore, there is a high probability that there are other factors at play.

However, there is no direct evidence yet.

Wang Zhaokai also ran over.

Hearing Lu Chuan's judgment.

"The handwriting wasn't his?"

"Yes, the handwriting was not written by him. Moreover, if Zheng Gaoxue committed the murder, what the other party wanted should be Qin Weiwei's money."

Zheng Gaoxue and Qin Weiwei broke up because of money.

So, if it was really Zheng Gaoxue who committed the murder, then why did he rape and humiliate Qin Weiwei after his death without taking any money?

The Criminal Police Brigade has already investigated Qin Weiwei's bank account transactions.

On the afternoon of the day of the incident, Qin Weiwei did transfer 2 yuan to Zheng Gaoxue.

Then there are no other transfer records.

Qin Weiwei has saved some money over the years as a graphic model.

Not only did he buy a house with full payment, but he also had a deposit of more than 200,000 yuan.

Of course, Zheng Gaoxue's suspicion cannot be completely ruled out.

Because no one can be completely sure how the font on the bathroom mirror is related to Qin Weiwei's death.

At present, these clues are just a guess.

"Would that person...let him go?"

"Wait first, let the other person stay overnight before talking. If it doesn't work tomorrow, let him go, but you must always monitor the other person's every move."

Although Lu Chuan's handwriting identification analysis ruled out Zheng Gaoxue, everything is possible.

For example, what if the murderer is not the same person?
Anything can happen.

the next day.

Zheng Gaoxue left the criminal police brigade.

The investigation of the case has now reached a bottleneck.

There are many clues, but they are basically broken.

How was the secret room murder carried out, how did the murderer do it, and how did he leave after that.

Everyone thought about it all night and still couldn't figure it out.

The door lock at Qin Weiwei's house is old-fashioned and can only be locked from the inside.

There were no traces of pedaling on the window, and it was closed inside.

Can the murderer turn into air?

How to do?
Lu Chuan returned to the crime scene again. (End of chapter)
