19: Wang Qingshan's son wasn't actually his.
"What are you going to do?" Wan Qiang asked while making tea.
Lei Zhen said, "Team Leader Wan, I heard that the entire Criminal Investigation Team Three is looking for the murder weapon and blood-stained clothes Wang Qingshan discarded, right?"
"That's right." Wan Qiang nodded.
Lei Zhen continued, "But we don't even know which direction Wang Qingshan ran after killing someone. Searching blindly like this is like looking for a needle in a haystack, so I think Wang Qingshan himself needs to confess."
"But he just won't talk," Wan Qiang's face was troubled. "And we can't use torture."
Lei Zhen directly pulled out a few playing cards. "Actually, many times, not speaking doesn't mean a person can hide their information."
"What is this?" Wan Qiang looked confused.
"Let's do a small experiment." Lei Zhen finished speaking and spread the playing cards on the tea table.
"Take a look at these five playing cards." Lei Zhen pointed to the table. "Choose one in your mind, but don't say it out loud."
Although Wan Qiang didn't know what Lei Zhen was up to, he still did as he was told.
"I've chosen one."
Lei Zhen collected the five playing cards, then took them out one by one to display.
"When I ask you, you can answer or not answer, or you can lie."
Lei Zhen spoke while staring into Wan Qiang's eyes, "Is it this one?"
"No."
"Is it this one?"
"No."
"Is it this one?"
"Not this one either."
"Then is it this one?"
"No."
"Could it be this one?"
Wan Qiang didn't answer this last time.
Lei Zhen shifted his gaze from Wan Qiang's eyes, then took out the Five of Spades.
"You chose this one, didn't you?"
Wan Qiang was stunned on the spot. "You...how did you know?"
Lei Zhen laughed heartily. "Actually, this is micro-expression analysis. When you see the card you've chosen, your expression will have very subtle changes.
Just now, when I asked about this Five of Spades, although you said no, your pupils clearly contracted slightly.
This is also one of the body's manifestations when normal people try to conceal a lie, and these are things that cannot be controlled.
Of course, my certainty that you chose the Five of Spades is not solely based on your pupil changes, but also on the assistance of other micro-expressions, which I won't go into detail about."
Wan Qiang was shocked after hearing this. "So micro-expression analysis is that powerful? When did you learn this skill?"
It must be said, Lei Zhen, this treasure boy, once again gave Wan Qiang a surprise.
Lei Zhen smiled calmly, "Actually, since I was thirteen, I've been determined to become a police officer, so over the years I've learned a lot of miscellaneous professional knowledge. In fact, it's all half-baked, and in front of you, it's just showing off a little."
Actually, Lei Zhen wasn't lying. He really had self-studied micro-expression analysis, but it wasn't very mature, nor had it been extensively verified. This small demonstration was also for easier explanation later.
Wan Qiang laughed after hearing him. "You don't need to be modest, kid. This ability is very useful! Alright, I know what you want to do. Whatever you do, I'll fully cooperate."
Lei Zhen's arrival rekindled hope for Wan Qiang, who had almost given up. So, he immediately asked, "Tell me, what are you going to do next?"
"First, give me half a day to conduct a background investigation on Wang Qingshan!"
——————
After Lei Zhen left the Municipal Criminal Investigation Team, he directly took a taxi to the building materials street where Wang Qingshan's paint specialty store was located.
Soon, Lei Zhen discovered a situation: Wang Qingshan was arrested on suspicion of murder, but his wife didn't seem anxious at all.
Of course, she had visited the detention center a few times, but the police didn't allow her to meet Wang Qingshan.
Logically speaking, if her husband is arrested, a wife should immediately find a lawyer for him, but this woman not only didn't find a lawyer, but still dressed up glamorously every day and continued to do business.
Li Jiajuan's behavior was clearly abnormal. She was more than ten years younger than Wang Qingshan, and Wang Qingshan was burly and had a fierce look. If you said this woman truly loved him, Lei Zhen really wouldn't believe it.
Soon, Lei Zhen discovered something: a young man of about thirty entered Li Jiajuan's shop, and after he went inside, Li Jiajuan pulled down the shop's shutter.
Half an hour later, Li Jiajuan reopened the rolling shutter, and her hair was noticeably messier than before.
And the man patted Li Jiajuan's butt before leaving with a satisfied expression.
"Is this what they call an affair?" Lei Zhen was startled.
Lei Zhen recalled what the villagers from Wang Qingshan's hometown had said; they mentioned that Wang Qingshan especially doted on his young wife, indicating that Wang Qingshan loved his wife very much.
If he knew he had been cuckolded, he would surely go mad!
It turned out that Wang Qingshan's weakness was his wife!
Soon, with Wan Qiang's help, Lei Zhen found the man's information.
This person was named Chen Zaiwei, a materials manager for a renovation company, meaning he was responsible for procurement.
When Wang Qingshan first started his paint shop, business was difficult because he had no foundation.
Later, he met Chen Zaiwei, who worked as a materials manager at a renovation company, through a friend, and the two quickly became acquainted.
It was also with Chen Zaiwei's help that Wang Qingshan's paint business gradually took off.
Wang Qingshan was very grateful to Chen Zaiwei, treating him like his own brother.
In business, Wang Qingshan relied on Chen Zaiwei, so the couple often invited him to dinner.
But despite Wang Qingshan's burly appearance, his alcohol tolerance was surprisingly poor; two bottles of beer could render him unconscious, even worse than his wife.
So, many times, it was Li Jiajuan and Chen Zaiwei who sent him home together.
This scenario reminded Lei Zhen of a Japanese romantic action film he had watched, where the adulterous couple played cards right next to the woman's drunk husband, a scene that was incredibly stimulating.
Lei Zhen guessed that Chen Zaiwei had done such things many times.
Also, Chen Zaiwei had already been married for a long time, and his wife was even introduced by Li Jiajuan.
Li Jiajuan and Wang Qingshan's son is only three years old this year, just starting kindergarten. Usually, their nanny picks up the child, but Lei Zhen noticed that this time, Li Jiajuan actually went to pick him up with Chen Zaiwei.
Moreover, judging from Chen Zaiwei's expression upon seeing the child, there must be an extraordinary relationship between him and the child.
So Lei Zhen called Wan Qiang and asked him to check Wang Qingshan and Li Jiajuan's blood types.
Li Jiajuan had a birth record at the hospital when she gave birth. Wan Qiang found out through the local maternal and child health hospital that Li Jiajuan had O-type blood, and the child had AB-type blood.
Wang Qingshan was given a reason to have his blood drawn and tested directly at the detention center, and it was soon determined that he also had O-type blood.
Many people may not know that two O-type blood parents cannot have an AB-type blood child.
In other words, Wang Qingshan's son is not his biological child.
Lei Zhen slapped his thigh, this scoundrel was even raising someone else's child.
And this child was most likely his good brother Chen Zaiwei's.
Now that Wang Qingshan was arrested, this adulterous couple must be overjoyed, hoping Wang Qingshan would be sentenced to death.
Without Wang Qingshan, Chen Zaiwei would dare to openly pick up his own child.
Wang Qingshan had spent his life bullying men and women and committing all sorts of evil deeds. When he forced others to watch him cuckold them, he probably never imagined that one day the boomerang would hit him.
As the saying goes, 'Good and evil will eventually be repaid, the cycle of heaven is just. If you don't believe it, look up, who has heaven spared?'
