Duan Ming retrieved the alarm records and police records of the fire accident in Wang Wenhui's house in the 119 alarm center, and the person who called the police was indeed Wang Qianshan, judging from the phone number of the police, Wang Qianshan should have used PHS at that time.

The time of receiving and dispatching the police was around 5 a.m. on November 13, 2001. At this point in time, it happens to be the time when people sleep the deepest.

The time when Wang Qianshan and Zhang Xiuwen registered their divorce from the civil affairs department was on November 18, 2001, which should have been after the funeral of Wang Wenhui and his wife. Wang Qianshan seems to be very anxious to divorce Zhang Xiuwen, even to the point that he doesn't want to wait a day.

All these prove that what Zhang Xiuwen said is true, and it is more in line with the logical order of Wang Qianshan's speculation that he killed first and then "fled".

At the same time, Duan Ming also brought a report on the accident investigation of the local fire department for that year.

Ma Hongwen took a cursory glance and was quickly attracted by some of the details, and immediately read it carefully from beginning to end, word by word.

Although this report is only a preliminary assessment based on the fire scene, judging from the contents, it is sufficient to identify the accident as a "fire" rather than an "arson".

The identified cause of the fire is basically the same as that described by Zhang Xiuwen.

The problem is that the preliminary identification results of the bodies of Wang Wenhui and his wife at the scene after the fire was extinguished were enough to make Ma Hongwen's jaw drop.

The preliminary identification at the scene is based on the judgment that various signs on the corpse can be observed with the naked eye, and there is no need for autopsy on the corpse.

Judging by the report.

First, the corpses were charred and even partially charred. If the assumption that Wang Qianshan killed his parents is valid and stayed at the scene of the fire afterwards, then it can be seen from this that he did not call the police until the fire burned for a long time.

Secondly, the bodies of the husband and wife were curled up. This is because the burning of the fire will cause the hands and knees to curl up. The arms will also be bent in front of the chest. This sign occurs because under the action of high temperature, the muscles of the limbs are hotly coagulated and contracted, which pulls the joints, and the muscles of tube flexion are stronger than the muscles of tube extension, so this sign of limb curl is formed.

Wang Wenhui's body lay curled up on the floor with its eyes and mouth open, less than 1 meter from the bedroom window; The old-fashioned safe, which was originally located in the corner of the wall, fell on the floor on its side and pressed against one of Wang Wenhui's palms, and the burning fire, the high temperature, and the high-intensity pressure of the safe made the pressed palm into a pile of charcoal powder.

Ruan Xianglan gritted her teeth and lips, and the body curled up and lay on her side on the bed.

The problem is that only people who have been burned alive will have these signs.

At the same time, Wang Wenhui's body was not far from the window, which indicates that he most likely escaped during the fire. The overturned safe indicates that he most likely wanted to step on the safe, then climb onto the windowsill and jump out of the window to survive. Due to his blurred vision and the tremendous force that erupted before he died, he accidentally knocked over the safe and smashed it on his own hand.

If Wang Qianshan has a lot of research on traditional Chinese medicine, he has a good understanding of the signs on the corpses of the living after they are burned to death, and even after the living people encounter a fire, their first reaction is to run away, and then put the corpses of their parents in various shapes that conform to the above appearances before arson, it can also be said.

The point is that there is a large amount of soot in the mouth and nostrils of the deceased. When the fire burns the body, only the living can struggle instinctively, and then the more they struggle, the wider the mouth opens, the more rapid the breathing, and the more soot is sucked into the mouth and nostrils, and finally the death is accelerated.

There was a clear cause of the fire, there were obvious traces of people being burned to death, and the family members were reluctant to perform an autopsy on the body, and they also believed that it was only a "fire" accident. Accordingly, there is nothing wrong with the fire alarm identifying this as a "fire".

Of course, what Ma Hongwen cares about is not the result of the fire alarm, what he cares about is that Wang Wenhui and his wife were actually burned alive, not that after being murdered, only the corpses were burned in the flames.

The finger bones provided by the old forensic doctor resurfaced. Thinking of the palm of Wang Wenhui's hand that was burned into charcoal powder, Ma Hongwen can basically determine that the owner of the finger bone should be Wang Wenhui. At the same time, it became the palm of charcoal powder, nor did it

It will make the fire police at the scene realize that Wang Wenhui's body is missing a finger.

If it is said that Wang Qianshan did not commit a crime of passion, and it was really a "fire", and Wang Wenhui and his wife simply died in the fire, then Wang Wenhui's fingers that were cut off, chopped off or cut off before the fire broke out, that is, before his death, cannot be explained.

There is only one possibility of such a contradictory situation: the perpetrators did not actually "kill" Wang Wenhui and his wife, but thought they were dead, and then hurriedly arranged the scene to create all kinds of "fire" traces. After the fire, Wang Wenhui and his wife suddenly woke up, and then tried to survive, but they were seriously injured and weak, and finally had to be "burned alive".

The question is, how did Wang Wenhui's finger bones escape the fate of being burned by the flames? Why is it in the hands of Wang Yuan'e again?

The father and son broke out into a fierce conflict, and even fought, Wang Qianshan was impulsive, used a sharp weapon, and slashed at his father. Wang Wenhui hurriedly stretched out his hand to resist, or wanted to snatch the weapon in Wang Qianshan's hand, but in the chaos, a finger was cut off, which is more likely.

Afterwards, the severed finger should also be left at the scene. Wang Qianshan took it away and carried it with him, and then "saw things and thought about people", and it was unlikely that he would use it as a memorial to his parents or to express his sorrow. Even so, it should not appear in Wang Yuan'e's hands.

Duan Ming's other discovery allowed Ma Hongwen to quickly answer this question.

In Wang Wenhui's old house, a piece of the cement crossbar laid on the kitchen sewer was turned over and set aside. The kitchen of the old house has an old-fashioned sewer design, and instead of sealing the pipes, the sewer is a concave sink with block-shaped cut-out cement bars as a cover.

This kind of sewer design is mostly found in rural areas and has a long history. With the rapid economic and social development, when Wang Wenhui opened the clinic, this place had developed into an urban-rural junction, and now it has become an urban area.

This type of drain is prone to odors and can easily damp the kitchen and breed mosquitoes. Wang Wenhui may have wanted to replace the sewer with a seal back then, so he would start repairing it.

In addition, the gas pipes are laid along the sewer and embedded in another groove, flush with the ground. Pipe***, which runs along the bottom of the corner and passes under the stove, next to the sewer pipe of the sink.

These are consistent with the records in the fire accident investigation report of that year, indicating that the old house was still repaired according to its original appearance after the fire, and has not been altered.

Since there has been no one to live in, the sewers that Duan Ming saw were naturally very dry.

Reminiscent of the old forensic doctor's speculation about the environment in which the finger bones might be stored based on the dried corpses of the gnats on the ring, the problem is solved.

The conflict between father and son should have erupted in the kitchen.

At that time, the sewer was being repaired, so Wang Wenhui should have lifted one, or even several cement pole covers. The severed finger flew into the sewer from the missing rod cover, landing in an imperceptible corner.

The ensuing fire quickly dried the drains. At the same time, the gnats inside died quickly due to extreme heat or extreme lack of oxygen, and several of them died on the ring. Since then, the old house has been uninhabited, the sewers have been kept relatively dry, and the gnats have become dried corpses, which have been preserved to this day.

In Zhang Pei's confession, he once said that Wang Yuange had returned to his hometown and was drunk alone that night.

The sewer pole cover that Duan Ming found that was lifted was most likely Wang Yuan'e's doing.

The saying goes, "As long as it's gold, it glows everywhere", which means that even in the corner of the sewer, a gold ring can still shine when the light shines.

But the glittering light of the gold ring left in the sewer, although faint, must be discovered before it can appear dazzling. As for whether its flickering light can be spotted, it all depends on the will of God.

Maybe it's the providence in the dark.

Wang Yuange went to the kitchen that night, maybe he was bored and wandered around, maybe he went to the bathroom connected to the kitchen to go to the toilet, maybe he wanted to smoke but couldn't find the fire, and he wanted to go to the kitchen to turn on the fire, who knows

Dao.

In short, in this process, the light from the ring that was left in the sewer finally intersected with Wang Yuan'e's line of sight at a fixed angle.

Out of curiosity, Wang Yuange lifted the rod cover, and finally found that his fingers had already become bones.

He was most likely taken aback.

After stabilizing his mind, he carefully took out the finger bone, and then took off the ring, and he also found the three words "Wang Wenhui" engraved on the inside of the ring.

What does this mean, Wang Yuange also quickly reacted.

So, he drank a lot of wine that night, and also talked to Zhang Pei about Wang Qianshan all the way through the strength of the wine.

There is no doubt that Wang Yuange is also suspicious of Wang Qianshan. Look at the book

Before this finger bone was discovered, Wang Yuange should never have thought that the death of his parents would be "homicide", let alone link the suspicion of the crime to his brother.

But this late finger bone turned his perception upside down.

Wang Qianshan, who was the first discoverer of the fire accident and the person who reported the incident, also refused to have his parents' bodies autopsied. These elements are only after determining that the parents are "killed by him", and then tasting them carefully, will they figure out a different taste and be creepy.

Thinking of the father-son relationship between his father and brother that seems to be becoming more and more "sabre-rattling", and as soon as his parents' funeral ended, Wang Qianshan couldn't wait to divorce Zhang Xiuwen, and then eloped with his "new sister-in-law", so all kinds of signs pointed to Wang Qianshan.
