Zhang Yichi was not in a hurry to speak, but stared at No. 1 while panting slightly.
No. 1 was a little uncomfortable being stared at. Just when he was about to speak, Zhang Yichi's eyes flickered and he spoke first: "If he had been pushed out, his body would have touched the edge of the window. But I took a look and there was something on the edge of the window.
There was dust, so I wrapped a cotton coat into a ball and stuffed it through the window that could only be opened a third. After the experiment, most of the dust on the edge of the window was rubbed away."
After hearing Zhang Yichi's reasoning, No. 1 turned to look at the edge of the window.
"It's impossible to push a person down without hitting the edge of the window when the window is fully open, let alone only a third of the way open?" Zhang Yichi continued, "If he hadn't been pushed down, he would have had no choice but to push him down.
It was your brother who jumped down by himself."
"You just used a screwdriver to unscrew the screws and stood up just to judge whether my brother jumped by himself?" No. 1 saw the traces of dust, and then looked down.
"Absolutely." Zhang Yichi looked around, trying to find more clues, "Because even if your brother committed suicide, he couldn't have done it with the window open a third, so even if he stepped on a stool, he would have to squeeze out.
He will still be rubbed. Unless the window is fully open, he can just kick on the window sill and then... jump out."
Number 1 disagreed with this idea: "So my brother committed suicide? Then why are we looking for two murderers?"
Zhang Yichi's mind came to a bold guess that No. 3 had told him: "It's suicide, but it's not suicide."
Number 1 was silent.
"There are no clues here." Zhang Yichi turned around and walked out of the balcony, "Let's go back to the living room."
The two returned to the living room.
Zhang Yichi sorted out the physical evidence, including a new mobile phone hidden under the mattress in the bedroom, his brother's notebook, and the half bucket of juice.
Other evidence: The younger brother did jump by himself.
He began to compare this evidence with the information gained from talking to the three personalities, which was a long process.
The previous suspicion of No. 1 mainly lies in what No. 2 said. No. 2 was eager to get rid of his own suspicion, so he said that No. 1 had the motive and conditions to kill his brother.
The suspicion of No. 3 is that he said that he drank juice and the juice was drugged, so he was very sleepy. He tied himself and his brother up early and went to sleep. But his brother couldn't untie the rope. How did he jump from the building?
Zhang Yichi is making deductions in his mind. The first deduction is if No. 1 and No. 2 are the murderers:
At midnight the day before yesterday, I woke up on the 1st, worked until 3am, and went to bed. I got up at 7:30, cooked and helped my brother wash up. Then I woke up on the 2nd, sent my brother to the billiard hall, and went to work. At noon, I went home on the 2nd.
One time, I drugged the juice and quietly unscrewed the screws of the balcony window so that the window could be fully opened.
At night, No. 3 felt sleepy after drinking juice, so he tied himself and his brother together to sleep. Between 9:30 and 10 o'clock, the younger brother somehow untied the rope and came to the window without knowing the motive.
, brought a stool and jumped down.
In the early morning, when he woke up on the 1st, he faked the chaos on the balcony, took away the stool, and then screwed up the window screws. Then he pretended to go out to look for his brother, and found that he had fallen to death.
There are several things that don't make sense about this conjecture.
What No. 2 did, No. 1 could do on his own. If he was afraid of being discovered by his younger brother, he could get up early and do something to the juice and windows while his younger brother was asleep. How did his younger brother untie the rope? Mingming
His intelligence cannot be solved. Why did the younger brother jump off the building? What happened that night?
Next, Zhang Yichi deduced what the process would be like if No. 2 and No. 3 were the murderers:
The day before yesterday, what No. 1 and No. 2 did after they woke up has not changed. The key point mainly happened to No. 3. After No. 3 went back, his brother jumped down the stairs between 9:30 and 10 o'clock. He personally caused the incident.
After passing the scene of the fight, he deliberately put himself into a very unfavorable situation full of omissions, and then lay down on the bed and fell asleep.
There are also doubts.
The window does not require No. 2 to go back at noon to do anything. No. 3 can do it by himself when he goes back. Looking at the traces on the window sill, the younger brother should have jumped out by himself. So how did No. 3 get his younger brother to jump out of the window by himself?
Regardless of whether No. 1 and No. 2 are the murderers, or whether No. 2 and No. 3 are the murderers, there is one unjustifiable point in these two speculations, that is, the existence of No. 2 is very unnecessary. The things that No. 2 did, regardless of whether No. 1
No. 3 and No. 3 can all be done by yourself.
But he passed the first round, and naturally he was sure that No. 2 was one of the murderers.
Why does the other murderer insist on teaming up with No. 2, which is unnecessary?
The traces of the fight on the balcony seemed to Zhang Yichi to be fake, very deliberate, and fake.
The key point is whether No. 3 forged it or No. 1 forged it.
If No. 1 forged it, then his purpose was to frame No. 3.
If No. 3 forged it, then his purpose was to put himself at a disadvantage, but these adverse evidences had relatively obvious omissions. Once these omissions are found, these adverse evidences will be overturned in an instant, and instead they will become framed.
The evidence supports No. 3. If this is the case, then Zhang Yichi has greatly underestimated No. 3’s courage and IQ.
Zhang Yichi said hello to No. 1, found a pack of cigarettes from the cabinet, pulled out one and started smoking.
The younger brother's diary contains a lot of content about playing with No. 3. He said that he liked the night very much. It must be that he and No. 3 had a good relationship. No. 3 had no obvious motive for killing.
On the contrary, No. 1 couldn't help but beat his younger brother because he gave up his studies and because his savings were wiped out.
Zhang Yichi still can't figure out what role that new mobile phone played in the case.
Other than that, it's just the half bucket of juice.
If drinking this bucket of juice does not make people particularly tired, then No. 3 is lying. If he was really drugged, can he tell that No. 1 is the murderer?
Zhang Yichi doesn't think so.
Because the juice was really drugged, it can be explained that it was drugged by No. 1 and No. 2. But it could also be drugged by No. 3 himself. He poured out half the bucket, lied to himself that he drank half the bucket, and then fell asleep.
Counter-framed No. 1.
Zhang Yichi still plans to try juice. It doesn't matter if the juice contains medicine. If there are no problems, then No. 3 is undoubtedly lying.
The balance of trust will tilt towards No. 1.
"Did you hit your brother half a month ago?" Zhang Yichi asked No. 1.
"I did." No. 1 admitted.
No. 1 was always sincere and readily admitted the evidence that would be used against him.
Zhang Yichi asked again: "Why didn't you tell me before?"
"I'm innocent. I felt that beating my brother half a month ago had nothing to do with the case, so I didn't say anything about it." No. 1 spoke smoothly without any lag, and it didn't look like he was making it up.
"Later, I want you to drink some of this juice and try it to see if it has been drugged." Zhang Yichi said, "The final result will be very helpful in solving the case."
