"Dong Yue is not a left-handed, but she just picked up the water cup with her left hand to drink water. Why did she do this?"

"Is it just a coincidence?" Minghui asked.

"No," Xiaobai explained: "It is a matter of using hands to rely on muscle memory. It is like when I eat with chopsticks with my right hand. This is something that does not require the brain to think about, because the muscles have formed an inherent habit.

Muscle memory is hard to make mistakes and is difficult to change unless it is conscious exercise and correction.

As a person who is used to using his right hand, Dong Yue holds a cup with his left hand to drink water, which must be the result of thinking intervention.”

Wu Cuo gave Xiaobai a thumbs up, "The knowledge is so wide!"

Xiaobai scratched his head embarrassedly, "Don't praise me, the two seniors must understand better than me."

Wu Cuo said again: "But, what does the problem of the left and right hands have to do with the case?"

"It's a big deal, and the key evidence of this case lies on Dong Yue's right hand!" Yan Ruyu said confidently: "If the murderer was Dong Yue, as a thin woman, even if Tian Xiaofang was not careful, she would not be able to push the person down at once. The two would pull or even fight.

During this process, Dong Yue's right hand must have been injured. She was afraid that I would see it, so she held the cup with her left hand."

"There is such a possibility," Wu Cuo nodded and shook his head again, "but there were no traces of fighting left on Tian Xiaofang's body, and no abnormal tissue samples were found in the cracks in his nails."

"The fight may not leave any traces 100%, especially when Tian Xiaofang had an advantage."

“Advantage?”

"Didn't the deceased Tian Xiaofang have the habit of smoking on the top floor? She was probably smoking when she was killed, and the cigarette butts in her hand could also be used as a temporary weapon."

"What do you mean is Dong Yue was burned?"

Yan Ruyu nodded, was silent for a while, and then combed from the beginning:

"At first, I thought the murderer was Wang Jianxin, because Tian Xiaofang's interpersonal relationships in the factory were very simple, and she was careless, so this kind of person is not easy to make enemies with others. Coincidentally, she and Dong Yue are very similar in size. Both of them are about 160 years old, with long hair. If they wear the same work clothes, they may still admit their mistakes at night.

I thought Wang Jianxin wanted to kill Dong Yue, but he mistakenly killed Tian Xiaofang.

After all, Wang Jianxin and Dong Yue have no emotional foundation, and everything is based on interests. Once interests cannot be satisfied, it is easy to cause resentment.

The above is my initial guess, but today I found that it is exactly the opposite.

The murderer is not Wang Jianxin, but Dong Yue!

Dong Yue is the only witness in this case. In addition, she had no interaction with Tian Xiaofang before and did not have any motive for murder, so we naturally chose to believe her.

The premise that is trustworthy is that she did not lie. During today's inquiry, I found that Dong Yue had a problem. Her description of the murderer's body shape was inconsistent, so I had another guess.

We overlooked one thing: Tian Xiaofang was not invited to the rooftop by someone, she went up to smoke by herself, and this matter was uncontrollable. The murderer could not have been ambushed on the rooftop and waiting for her to come."

Wu Cuo thought, "So it was a temporary intention and murdered passionately! Suppose Dong Yue knew that it was Tian Xiaofang who was blocking her promotion. Two women with hot tempers had a dispute over this matter, which eventually led to a tragedy."

"This is one possibility, but I prefer another possibility."

"Another possibility?"

“Yes, another...well, a darker possibility…

The most suspicious point is the relationship between Dong Yue and Wang Jianxin. Although both of them were so squeamish that they were reluctant to admit it, it can be seen that Wang Jianxin really wanted to cover up his shame. If Dong Yue had not admitted it, he would definitely not have told him about it.

Dong Yue is different. Although she acted unwilling to admit it, she confessed her relationship with Wang Jianxin when you first asked. This is intriguing. She could find any reason, such as working overtime is too tiring and coming to the rooftop to breathe. Why do you admit that it is to date Wang Jianxin?

Doing this will only lead to one result, which is to expose Wang Jianxin to the police's sight. What are the benefits of Wang Jianxin's exposure to Dong Yue?

A message provided by Wang Jianxin today answered my doubts. He said that Dong Yue was forcing him to divorce..."

"Wait," this time, Wu Cuo was really at a loss. "I can't keep up with your ideas. What does it have to do with divorce?"

Xiaobai and Minghui also nodded together. The first time they encountered Yan Ruyu and Qingqi's imagination, they were even more confused.

Yan Ruyu explained: "Think about it, why did Wang Jianxin not have absent? Isn't it because Dong Yue asked Wang Jianxin to go to the office? Dong Yue was the only witness in the fall of the building. It can be said that if there is no direct evidence, the main basis for our case is Dong Yue's testimony. Whoever she points to, will become the key suspect.

With this advantage, Dong Yue can negotiate terms with Wang Jianxin. If Wang Jianxin does not meet her requirements, she will accuse Wang Jianxin of being the murderer, ask the police to investigate him, and make all his bad things in the past public. Isn’t this what Wang Jianxin is most afraid of?

This can also explain why Dong Yue’s description of the murderer’s body shape is ambiguous. During the negotiations with Wang Jianxin, she would of course try her best to prove that the murderer was not Wang Jianxin.

However, once the negotiation fails and Wang Jianxin does not agree to her request, she will stand up and point out, saying that the murderer is Wang Jianxin.

Therefore, the statements before and after are too different, otherwise it will arouse our suspicion. Dong Yue’s description of the murderer is to fool us and try to divert our attention.”

"But...If Wang Jianxin is threatened by Dong Yue, why doesn't he tell us?"

"Because it's better to have less things than more things. Dong Yue hasn't framed him yet. Of course, he has to try every means to deal with us less. People have done ugly things and have a ghost in their hearts. Even if they become victims, they are afraid of dealing with the police."

Xiaobai raised his hand weakly, "That... although I probably understand your logic,... this is a bit too mysterious, right? What do you mean is that Dong Yue pushed Tian Xiaofang down purely to frame Wang Jianxin?"

Minghui echoed: "Yes, this...is unlikely."

Yan Ruyu did not refute the two of them, but said: "Of course, before finding conclusive evidence, everything is just a conjecture, and the evidence, I think, is related to Dong Yue's right hand.

Just get a search warrant and ask Minghui to search her body and you will know the truth."

"No problem, the search warrant was completed today!"

As Yan Ruyu expected, Minghui found a burn at the connection between Dong Yue's right palm and wrist. It was red and could not be covered up no matter what.

"Why, I accidentally burned it, you guys care about it?" Dong Yue covered up the panic in her heart with a tough attitude.

"How did you get burned?" Yan Ruyu refused to give in.

"I... can eat barbecue hot food, right?"
