Compared with the truth of the case, more people marvel at Xu Guolis skillful criminal techniques and strong psychological quality.
In this almost live investigation process, Xu Guoli talked to the camera many times with a calm look.
And the interview place, it is in his own home, that is, the crime scene.
From the crime to his arrest, he lived there as usual.
In the face of the criminal evidence to be exposed, he pretended to turn his head twice, and then he walked away as if nothing had happened.
This kind of psychological quality cannot be achieved by ordinary people.
Lets talk about the modus operandi.
Ms. Lai appeared in the elevator monitoring of the community on June 4 and disappeared on June 5.
In other words, Xu Guoli only spent one night to deal with the scene almost quietly and without leakage.
Therefore, many people suspect that Xu Guoli is skillful and may not have committed the crime for the first time.
In 2002, her 16-year-old daughter, who was found lying on the bathroom floor with a hole in her right neck, died.
There were two important clues at that time.
One is that the doors and windows of the house are not damaged.
Probably the daughter opens the door to acquaintances.
Second, witnesses said that between 3:30 and 4:00 p.m., she saw a man walking out of Ms. Lius house. He was a little more than 1.70 meters tall and thinner.
On the day of Lius daughters funeral, Xu Guoli went to attend and bought a shroud for the girl.
At present, the police have been focusing on Xu Guoli and launched a new investigation into the old case 18 years ago.
If the final investigation shows that the murder of Miss Lius daughter is indeed what Guo Guoli has done.
After his daughter died, Xu Guoli still kept a good friendship with Ms. Lius family.
Ms. Lius younger brother once asked Xu Guoli to be responsible for the management of accounts and procurement. After the demolition of Xu Guolis duck farm, she borrowed 1 million yuan from her, and then paid off one after another.
This can be said to be the meaning of wealth, which can be regarded as a close friend.
According to the survey, 70% of the murders in the world happen among acquaintances.
The perpetrator may be the victims friend, relative, client, neighbor, lover And even close relatives by blood.
In the secret corner, all unexpected things may happen.
Until 2016, new progress was made in DNA technology, and the suspect Gao Chengyong was finally arrested and confessed.
In this regard, people around Gao Chengyong are very surprised.
In their opinion, Gao Chengyong usually treats people well, behaves politely, and works steadily.
He and his wife opened a canteen in the school. They lived a carefree life. Their two sons got excellent grades and found good jobs.
In the process of his confession, Gao Chengyong can remember 11 cases clearly, even to that month of that year, several minutes and seconds.
He may have recalled these scenes countless times in the dead of night.
Some people say, this is too dark, why should we know such a dark and secret corner?
Because of darkness, it doesnt really exist because you pretend it doesnt exist.
As one Zhihu netizen said: there are many fears in life: there may be parasites in meat, pesticide residues in tomatoes and cucumbers, people cant see bones, and all the peace we see is appearance.
Only by acknowledging this can we become more cautious.
A common feature of the suspects in serial cases is their super conceit.
For example, Gao Chengyong in the silver chain case.
He confessed that after killing the 8-year-old girl, he suddenly felt thirsty.
Then he took the tea from the victims home, made a cup of tea, washed the scene after drinking, and left!
This kind of persons mentality is: once or twice do evil without punishment, they will have a I am very clever idea, and then continue to challenge the bottom line.
Xu Guoli in the interview, also unintentionally revealed a few conceit.
The implication is that the wife to her, is a low IQ, very easy to control the person.
He has a high IQ and should be richer than his wife.
No one knows what this conceit comes from.
I personally think it is very necessary.
Fortunately, with the rapid development of detective technology, people who are trying to challenge the bottom line have no chance to take advantage of it.
Xu Guoli certainly didnt expect that his well thought out plan would come to light in the dung water of 38 trucks.
I hope that this defeat for him can defeat the conceit for no reason and more people who think they are wise.
Dont underestimate todays detective technology, not to underestimate the polices determination to detect homicide cases!
