Xu Xinger finally interjected: "In the end, you still think that the corpse is Du Xiaoze, you think that Wei Wuxian disguised Du Xiaoze's body as his own, and Wei Wuxian is the real murderer." ”

"Yes."

Zang Hongbo said: "You can't just rely on conjecture, is there any other evidence?" ”

There are several points to corroborate, the first is the human relationship. The simplest emotion, Old Man Du's family was killed, without looking at any clues, everyone first based on their first feeling, son-in-law and son, who is more likely to be the murderer?

The answer in your mind is not entirely speculation and speculation, but a matter of probability.

And the relationship between uncle-in-law and mother-in-law and daughter-in-law is actually very delicate, many contradictions are not known to outsiders, and most of Wei Wuxian's monthly salary is also on the father-in-law's card.

Life and case-handling experience have actually told you that the probability of a son-in-law being a murderer is much higher.

The relationship between sons is different, after all, the blood relationship is there, and a little contradiction is easy to resolve.

Plus...... I agree with what Xiaobai just said, judging from the state of life, Du Xiaoze is a wasted person, he has neither motive nor this statement is arbitrary, but judging from the existing information, does he really have the ability to commit crimes?

Of course, reasoning cannot be based on first impressions alone, and there are a few points that can support my thoughts.

First of all, the location of the crime.

If Du Xiaoze kills people so recklessly, the best place to kill should be his parents' house where he lives, and he has a home advantage, so why run to his sister and brother-in-law's house? It's too hard to ask your parents over individually, and it can't be justified.

The location of the crime proves that the murderer is Wei Wuxian.

Secondly, the time trajectory of several people involved in the case.

The corpses were charred, and there was no way to determine the time of death, but we only knew a few important points in time on the day of the crime:

14：07； The neighbor knocked on the door for the first time and asked Wei Wuxian about the quarrel between the two of them. Around this time, another neighbor who was on the lawn of the community with his grandson saw Wei Wuxian go downstairs to pick up a taxi.

According to the neighbor's recollection, a young woman got out of the taxi, and the young woman was not Wei Wuxian's wife, Du Ruo, and the neighbor recognized Du Ruo.

Who could the young woman be? It's Du Ruo's brother-in-law!

It's a pity that the neighbor can't remember the specific time at that time, and can only recall that it was about one to two o'clock. Based on this, we can reasonably speculate that the younger brother and daughter-in-law received a call at 13:28 and took a taxi to the sister-in-law's house, and arrived at the place at about 14:00.

At 14:07, the neighbors across the door heard the quarrel, but it was not Wei Wuxian and his siblings arguing and shouting, but Wei Wuxian and his younger siblings.

The quarrel between these two people is intriguing.

One is Du Ruo's husband and the other is Du Xiaoze's wife. The connection between them is actually through the Du family sisters and brothers. It seems that there are only two people separated by them, but in real life, they are separated by thousands of mountains.

I don't have much experience in life, but you ......," Yan Ruyu glanced at the elders who attended the meeting, "You should have the best experience, in actual life, this kind of relationship is a little bit of a word."

They belong to different small families, so they can pass on face, hello, hello, everyone. It's not too intimate, and it's not too prone to any direct contradictions.

Therefore, these two people can quarrel, and they quarrel to the point of squeaking and screaming to alarm the neighbors, no matter how you look at it, there is a sense that they will never get along again after breaking the can.

It's not, I'm going to kill the whole family anyway, and I still get along with a fart.

Third, burn the corpse.

The water content of an adult's body is about 65% of a person's body weight, in other words, a person is not a flammable thing, and it is quite difficult to burn five corpses into charcoal.

Even if there is a funeral home's professional crematorium, it will burn for more than ten or twenty minutes.

The murderer is at home, although there is gasoline to help the combustion, but considering that the fire is not too big to attract attention, and it is not enough to make the smoke billow, this operation will be carried out much slower......"

Xu Xinger rubbed his temples, "So...... You were burning in the autopsy room...... Half a pig, just to experiment with this? ”

When Yan Ruyu borrowed the autopsy room, he only greeted Xu Xinger, and the other people in the meeting didn't even know about Wu Cuo.

Yan Ruyu said calmly: "Well, including the bones and meat, as well as the internal organs, a total of more than 60 kilograms, it took one and a half hours to burn to the extent of a corpse."

Belch...... By the way, I paid for the meat myself, this is the invoice," Yan Ruyu took out an invoice from his pocket: "Please reimburse me." ”

The corners of Zang Hongbo's eyes twitched twice. It's no secret that the Jingbei City Serious Crime Team is well-funded, but he really can't imagine that these people are spending their money in such a strange place.

Yan Ruyu ignored his reaction and continued: "I think the murderer should have put the corpse in the kitchen and burned it, and at the same time used a range hood to extract the smoke from the incineration.

It takes about an hour and a half to incinerate the first corpse, and even if you have the experience of incineration, you can shorten the incineration time to one hour, or even less than one hour, and it will take about five corpses about five hours......"

Xiao Bai raised his hand and interrupted: "Is it possible to burn two or even more corpses at the same time, which is more time-saving." ”

"The killer may have tried to do this, but it won't be successful."

"Oh?"

"During the experiment, I found that I need to keep an eye on the fire. If two bodies are burned at the same time, the smoke is too big, and the fire is too big to control. Besides, there is gasoline, which is easy to get dangerous. ”

Seeing that there was no doubt, Yan Ruyu continued: "Then let's count the time."

17：03； The supermarket's surveillance captured Wei Wuxian's attention at the checkout, this was Wei Wuxian's last appearance, and he was the last of all the dead and missing.

until 22:50; The explosion broke out, and the neighbors fled in a hurry.

It was more than five hours in between.

The time left for the killer to burn the body is actually very limited.

To put it bluntly, there was no time left for the murderer to kill Wei Wuxian, who had just returned home. ”

In the end, Yan Ruyu concluded: "The murderer is Wei Wuxian. ”

Minghui thought about it carefully.

Previously, according to the autopsy report, Minghui unconditionally believed that Wei Wuxian was dead, and the biggest suspect was Du Xiaoze, but he vaguely felt that some details were unreasonable. Now that she has listened to Yan Ruyu's analysis, her wisp has been reduced by seventy or eighty percent.

She decided to believe Yan Ruyu.

"That's right," Minghui said, "There is a clue that I have been ignoring before. ”

"Oh?"

The day before the incident, Wei Wuxian had called his ex-wife and also called a bank to make an appointment for a large withdrawal.

He explained on the phone that the person who made the withdrawal was not him, but a friend of his, and I think the friend should be his ex-wife.

After investigation, the bank branch that Wei Wuxian made an appointment with was near the store of his ex-wife's house, if the murderer was Wei Wuxian, it would make sense. Minghui looked at the character relationship diagram drawn in his notebook, and slowly explained: "Wei Wuxian divorced his ex-wife because of the intervention of the junior, and this mistress is his current wife Du Ruo.

If the situation was as Brother Yan said, for whatever reason, Wei Wuxian had murderous intentions towards the Du family, and he himself had the will to die, then what would he think of before he died? It is likely to be a well-deserved ex-wife.

He has no other way to compensate but to leave the only money he has left to his ex-wife......"

Yan Ruyu asked, "Have you investigated his ex-wife?" ”

"The investigation is very detailed, because of the testimony of the neighbors, we have previously focused on the conflict between Wei Wuxian and Du Ruo between the husband and wife.

We speculated at the time...... The reason why Wei Wuxian had a big quarrel with his wife Du Ruo and quarreled with the Jingdong neighbors was because his wife found out that he was in contact with his ex-wife, and planned to give his ex-wife a sum of money at least to his ex-wife for safekeeping.

However, when visiting Wei Wuxian's ex-wife, the other party not only admitted that he had received a call from him, but also refused Wei Wuxian's request to meet on the phone.

According to his ex-wife, the two hadn't seen each other in years, and she was also shocked when she suddenly received a call from Wei Wuxian. ”
