In the interrogation room, Zheng Gaoxue was so frightened by Wang Zhaokai that he broke into a cold sweat.
What is certain from all the investigation results so far is that Zheng Gaoxue met Qin Weiwei himself in the afternoon of the day of the incident.
The other two were lovers before, and the breakup process was very unpleasant.
Zheng Gao Xueben 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 is 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 when you didn't kill her?"
"I'm a big man... I stole money from my girlfriend... It's embarrassing to tell anyone."
Wang Zhaokai...
"Do you know where this place is? This is the Criminal Police Brigade!"
"Disgraceful?
Thank you for thinking it through. "
Another office.
" Lu, if this Zheng Gaoxue is the murderer, there is a high probability that he is trying to make money. "
"However, the valuables in the deceased's home were indeed not lost, and there were 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 needs to verify it.
The murderer was at the scene, but not nothing was left behind.
The four characters on the bathroom mirror are the most powerful identification clues.
"Judging from the handwriting, it doesn't look like it."
Lu Chuan has the handwriting identification and analysis ability rewarded by the system. He just asked for the slip signed by Zheng Gaoxue, just to see whether his handwriting and what was left on the bathroom mirror I wonder if the four characters in my destiny can be matched.
"In this case, let Zheng Gaoxue copy this and bring it to me later."
The most rigorous handwriting identification analysis is to compare the original characters, that is to say, what kind of comparison you want to make words, let the other person write what kind of words.
Although Lu Chuan just found that the signature on the other party's name did not match, he still decided to compare it with the original characters in order to be more safe.
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.
The other thing is that when 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 too 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."
Four hours, faced with so much evidence, if it were an ordinary person, he would have given up long ago.
"Okay, you rest for a while. The Army Corps asked me to take this in and let Zheng Gaoxue copy it."
Wang Zhaokai took a look...
"Information letter?"
< br>As a suspect, Zheng Gaoxue had 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: "The Lu team asked to compare his handwriting. There are some words on it that are the same as those on the bathroom mirror."
" Okay, you take a rest first, I'll go in."
"Okay."
Wang Zhaokai went back to his office, took a drink of water, and took a rest. Four hours later, my mouth was dry.
Chen Jiang's side went very smoothly. In less than ten minutes, the copying was completed.
Lu Chuan’s office.
After receiving 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.
“It’s not him.”
From the perspective of font identification and analysis, the same font will reveal some details even if the other party deliberately conceals it.
Coupled with the comparison of other font strokes, Lu Chuan could confirm that the words on the bathroom mirror at the crime scene were not written by Zheng Gaoxue.
“The autopsy results showed that Qin Weiwei actually 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."
There is actually a consensus within the criminal police brigade on this judgment. .
You can imagine that Qin Weiwei lives alone, but in the middle of the night, he sees 4 words on the bathroom mirror to kill me.
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.
So, there is a high probability that there are other factors at play.
However, there is no direct evidence now.
Wang Zhaokai also ran over.
I heard Lu Chuan’s judgment.
"The handwriting was not written by him?"
"Yes, the handwriting was not written by him. Moreover, if Zheng Gaoxue committed the murder, the other party should want Qin Weiwei's money."
Zheng Gaoxue The reason why he and Qin Weiwei broke up was 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.
On the afternoon of the day of the incident, Qin Weiwei did transfer 20,000 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, 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.
Currently, these clues are just a guess.
"That person... should he be released?"
"Wait for a while, let him stay with him all night, and then let him go if it doesn't work tomorrow, but he must always monitor his 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 detection of the case has now reached a bottleneck.
There are many clues, but they are basically broken.
Secret room murder, how it was done, how the murderer moved his hands, and how he left afterward.
Everyone thought about it all night but 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.
The window showed no signs of being stepped on, and it was also closed inside.
Can the murderer turn into air?
What to do?
Lu Chuan returned to the crime scene again. (End of this chapter)
