"But Zhang Guanghui's fingerprints were erased." Huo Yan pointed out the most critical point.

Ning Shuyi was thoughtful.

"Thinking about it this way, there is another detail that is also worth playing." She was silent for a while, and then said to Huo Yan, "Do you remember the unused cement piled up at the crime scene?" There's a lot left!

If Chang Junchao wanted to kill two people and stuff it into that bath and fill it with cement, it didn't seem that he needed to buy so much, and he couldn't have predicted in advance that a habitual thief would appear.

In the past two days, I also called my dad and asked him how much cement he would need to build a bath to the same size as the crime scene.

My dad helped me estimate that the amount was much less than the one at the crime scene, and I didn't need to use that kind of hard one.

Furthermore, there is no reason for a person who wants to rebuild the pool to buy only cement and not bricks.

So I'm thinking that the most reasonable explanation is that he originally planned to kill Deng Qingrong and bury the body with cement, so that more cement is needed.

Unexpectedly, he was bumped into by a habitual burglar halfway, and he could only kill people, and it happened that the habitual thief also had scars on his back, which made him rise to the idea of pretending to kill the door.

In this way, the bath that was originally stuffed with one person became stuffed with two people, and the habitual thief was originally lean, but he had recently gained fortune, and his figure was more similar to Chang Junchao, so that after burying the two corpses, the cement was not used up. ”

Huo Yan nodded, indicating that he agreed with Ning Shuyi's speculation.

But Ning Shuyi still had a confused expression: "But why did Chang Junchao kill Deng Qingrong?"

For so many years, he has always been obedient, taking care of Deng Qingrong and Chang Rong, and being a filial son, which can be confirmed from the mouths of the old neighbors at the two addresses, and there is no rebellion.

He is an adult male with the ability to live, and from the fact that he lived normally alone after Deng Qingrong left home, he did not have any dependence on Deng Qingrong in life or spirit.

If it was because of his mother's extreme desire to control that made him feel suffocated, he could choose to separate, or come to the same trick that many teenagers will do - run away from home!

Either way, it's much cheaper than killing people, right?

What drove him to make such an extreme choice? ”

"It's the pain that comes from numbness and despair, and suddenly a glimmer of hope is ignited, but soon that hope is shattered again." Huo Yan said.

His tone sounded calm, but there was something in his eyes.

It was a complex emotion, and Ning Shuyi saw it in his eyes, and he couldn't interpret it for a while, so he chose not to touch it.

"Tell me more." She nodded to Huo Yan.

"In the morning at Zhang Guanghui's house, Zhang Guanghui mentioned that when she went to argue with Deng Qingrong, Chang Junchao's actions could see some problems, and it was obvious that over the years, in the face of Deng Qingrong's various tosses and actions, he was very painful.

And Deng Qingrong himself doesn't seem to be particularly satisfied with his son, otherwise he wouldn't have learned that his biological daughter Zhang Guanghui, who had been abandoned for 30 years, would also try his best to harass him, hoping to get certain benefits from his biological daughter.

She even verbally humiliated her son mercilessly in front of her own daughter. ”

Ning Shuyi was also very impressed by this detail mentioned by Zhang Guanghui, although she did not have this kind of experience in her growing up environment, but the feeling of being counted out by her parents in front of others is very depressing and painful to think about.

"The woman we helped before who was subjected to domestic violence, Wang Hongzhen, she also mentioned that after Chang Rong was seriously ill and Deng Qingrong packed up and left the house alone, until Chang Rong passed away, Chang Junchao dealt with his father's funeral alone, and Chang Junchao was very calm during the whole process.

From the beginning to the end, there was no resentment towards the mother's departure, and it can even be said that everything was as usual and was not affected in the slightest.

I don't think this is a simple manifestation of resignation, he was able to defend Zhang Guanghui and argue with his mother for a few words, which shows that he is not a person who is 100% obedient to Deng Qingrong's values, and has his own ability to distinguish between right and wrong.

In this case, Deng Qingrong abandoned her son and seriously ill husband and left alone, and she left for more than half a year, Chang Junchao did not have any emotional fluctuations from beginning to end, lived as usual, and did not ask anyone about Deng Qingrong's whereabouts, I think this shows that he is not rejecting such a situation in his heart, and even likes it very much. ”

Ning Shuyi sighed: "Deng Qingrong is at home, he has to take care of two people, Deng Qingrong is gone, he only needs to take care of a seriously injured father in bed, there is no way to pick and choose his father, maybe he will indeed feel a lot easier."

Originally, he didn't seem to have received any care from his mother, so no matter where Deng Qingrong went, as long as he left this home, it might be a relief for him?

After all, a mother who would take the initiative to tell her neighbors about her son's physical defects outside the home...... It may indeed be a source of mental torture! ”

"It's a pity that after that, Deng Qingrong came back." Huo Yan exhaled slowly, as if something was accumulating in his chest, "Just when Chang Junchao rekindled his hope for a good life, Deng Qingrong came back again.

All of a sudden, his life was back to the way it was, and it was likely that this was the turning point that led to his eventual collapse. ”

"I used to be able to endure it for twenty or thirty years, why can't I stand it after my mother runs away and comes back?" Ning Shuyi was a little puzzled.

"Have you ever been hungry?" Huo Yan asked Ning Shuyi.

Ning Shuyi shrugged his shoulders and shook his head.

For such an answer, Huo Yan was obviously not surprised at all, after all, he had been to Ning Shuyi's house, whether it was the economic conditions of her family, or the care and love of Ning's father and Ning's mother for their children, they would never be the kind of person who would let their children starve and freeze because of poor care.

"Going hungry isn't really that hard." Huo Yan's tone sounded very calm, without a trace of emotion, "If you have been hungry from the beginning, and have always maintained a state of starvation, people can bear it, as long as they don't starve to death, even if they are half hungry every day, they will not collapse."

But if at this time, all of a sudden, the person is fed every day, and after a while, suddenly the person who has been accustomed to eating and drinking enough every day is thrown back into the environment of starvation......

Do you think he'll be able to hold on as much as he used to? ”
