"Dong Yue is not left-handed, but she just drank with a glass of water with her left hand, why did she do this?"

"Could it be just a coincidence?" Minghui asked. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"No," Xiaobai explained, "the habit of using the hand relies on muscle memory, for example, I eat with chopsticks in my right hand, this matter does not need to be thought about by the brain, because the muscles have formed an inherent habit."

Muscle memory is almost infallible and difficult to change unless it is consciously exercised and corrected.

Dong Yue, as a right-handed person, uses his left hand to drink water from a cup, 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 know better than me." ”

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

"The relationship is big, and the key evidence in this case is on Dong Yue's right hand!" Yan Ruyu said firmly: "If the murderer is Dong Yue, as a thinner woman, even if Tian Xiaofang is unprepared, she can't push people down at once, and the two will pull and even scuffle."

In this process, Dong Yue's right hand should have been injured, and she was afraid that I would see it, so she used her left hand to hold the cup. ”

"There is such a possibility," Wu Cuo nodded, and shook his head again, "But Tian Xiaofang's corpse did not leave any traces of fighting, and no entrained abnormal tissue samples were found in the cracks of the nails. ”

"Fighting doesn't necessarily leave 100% traces, especially when Tian Xiaofang had another advantage."

"Advantage?"

"Didn't you say that the deceased Tian Xiaofang had the habit of smoking on the top floor? It is likely that she was smoking at the time of her murder, and the cigarette butt in her hand could also be used as a makeshift weapon. ”

"You mean, Dong Yue was burned?"

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

"At first, I thought the murderer was Wang Jianxin, because Tian Xiaofang's interpersonal relationship in the factory is very simple, and she has a big personality, this kind of person is not easy to make enemies with others, coincidentally, she and Dong Yue's size is very similar, both of them are about 160, thin, long hair, if you wear the same work clothes, it is still possible to admit mistakes at night.

I thought Wang Jianxin wanted to kill Dong Yue, but killed Tian Xiaofang by mistake.

After all, Wang Jianxin and Dong Yue have no emotional foundation, everything is interest-oriented, and once the interests cannot be satisfied, it is easy to breed resentment.

The above was my initial conjecture, but I realized today that it was quite the opposite.

The murderer is not Wang Jianxin, but Dong Yue!

Dong Yue is the only eyewitness in this case, and since she had no intersection with Tian Xiaofang before, there was no motive for the killing, so we naturally chose to believe her.

The premise of being credible is that she didn't lie, and in today's inquiry, I found that there was something wrong with this Dong Yue, and her description of the murderer's body type was inconsistent, so I had another conjecture.

We ignored one point: Tian Xiaofang was not asked to go to the rooftop of the top floor, she went up to smoke by herself, this matter is uncontrollable, and the murderer cannot always be ambushed on the top floor waiting for her to come. ”

Wu Cuo pondered: "So it's a temporary intention, killing people with passion!" Assuming that Dong Yue knew that it was Tian Xiaofang who hindered her promotion, the two hot-tempered women had a dispute over this matter, and finally caused a tragedy. ”

"It's one possibility, but I'm more inclined to another."

"Another possibility?"

"Yes, another ...... Well, a more shady possibility......

The most suspicious point lies in the relationship between Dong Yue and Wang Jianxin. Although both of them squirmed and didn't want to admit it, it could be seen that Wang Jianxin really wanted to cover up his shame, if Dong Yue hadn't admitted it, he would definitely not have told it.

Dong Yue is different, although she made a gesture of reluctance to admit it, she confessed her relationship with Wang Jianxin when you first asked. This is intriguing, she can find a reason casually, such as being too tired from working overtime, and came to the rooftop in order to breathe, why should she admit that it was to date Wang Jianxin?

Doing so will only lead to one result, that is, to expose Wang Jianxin to the eyes of the police, what is the benefit of Wang Jianxin's exposure to Dong Yue?

Today, Wang Jianxin provided a message that answered my doubts, he said that Dong Yue was forcing him to divorce......"

"You wait," this time, Wu Cuo was really at a loss, "I can't keep up with your train of thought, what does it have to do with divorce?" ”

Xiaobai and Minghui also nodded in unison, and the first time the two came into contact with Yan Ruyu Qingqi's brain, it was even more foggy.

Yan Ruyu explained: "Think about it, why didn't Wang Jianxin have an alibi? Isn't it because Dong Yue asked Wang Jianxin to go to the office? And Dong Yue is the only eyewitness in the falling case, it can be said that if there is no direct evidence, the main basis for our case is Dong Yue's testimony, who she identifies, who will become the key suspect.

Occupying this advantage, Dong Yue can negotiate conditions with Wang Jianxin, if Wang Jianxin does not meet her requirements, she will identify Wang Jianxin as the murderer, let the police investigate him, and make all his past bad things 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 type is ambiguous, and during the negotiation with Wang Jianxin, she will of course try her best to prove that the murderer is not Wang Jianxin.

However, once the negotiation failed and Wang Jianxin did not agree to her request, she would stand up and identify it, saying that the murderer was Wang Jianxin.

Therefore, there is too much discrepancy between the before and after statements, otherwise it will arouse our suspicions. Dong Yue's description of the murderer now is to fool us and want to divert our attention. ”

"But...... If Wang Jianxin was threatened by Dong Yue, why didn't he tell us? ”

"Because more is better than less, Dong Yue hasn't framed him here, of course he has to find ways to deal less with us. People, who have done ugly things, have ghosts in their hearts, and even if they become victims, they are afraid of dealing with the police. ”

Xiao Bai raised his hand weakly, "That...... I understand your logic, but ...... That's a bit too mysterious, isn't it? Do you mean that Dong Yue pushed Tian Xiaofang down purely to frame Wang Jianxin? ”

Minghui echoed: "Yes, this ...... Unlikely. ”

Yan Ruyu did not refute the two, but said: "Of course, until we find conclusive evidence, everything is just speculation, and the evidence, I think, is related to Dong Yue's right hand."

Get a search warrant and let Minghui search her body, and you can know the truth. ”

"No problem, the search warrant is ready today!"

As Yan Ruyu expected, Minghui found a burn at the junction between Dong Yue's right palm and wrist, which was red and couldn't be covered up no matter what.

"What, I accidentally burned, you don't care about this?" Dong Yue used a tough attitude to cover up the panic in his heart.

"How did you get burned?" Yan Ruyu did not relent.

"I ...... It's always okay to eat barbecue, right?! ”
