So far, except for Zheng Can, Zheng Can's uncle and Zheng Yanwu, all other clues that can be verified have been verified.

The people who were shareholders with Zheng Yanwu at the beginning were Liu Weiguo, Sun Yaowu, Li Yonghong, Zhai Xinghua, and Wang Zhenhua, all of whom were men. After Zheng Yanwu sold his shares, all five of them used their own money to buy a part, and there was no problem on the books.

Now, Liu Weiguo has passed away, and he was originally the new largest shareholder, but after his death, the shares were split among several sons and nephews, and these people were not good birds, and many of them were almost defeated.

Although the other four are still alive, three have already emigrated, and some of the shares have been retained and some have been sold.

The only one in China, only Wang Zhenhua, is not in the local area, and this person's shares have also been sold a lot.

At present, the company has more than 1% of the shares, as many as 17, and dozens of small shareholders scattered around, and now the company's situation, no one has the ability to condense into a rope.

The police also contacted Wang Zhenhua, who did not know much about Zheng Yanwu's original incident.

At present, the people who know the most about this case are the seven or eight policemen who went to the scene to investigate. At that time, the approval of the fire protection type was all in the public security bureau, so there was no fire liability certificate like now, and the police were responsible for the materials at the scene.

The times are different, and if it were now, this kind of thing would not have happened, but before 1995, many things really didn't seem rigorous enough now.

The police, who still had an impression of the scene, said that there was indeed a gas leak at the scene. At that time, gas was still rare, and it was said that it was gas, but it was actually similar to the current liquefied gas cylinders, but Zheng Yanwu had several tanks at home.

In the case of methane, for example, the calorific value of 1 kg of methane is equivalent to 13 kg of TNT equivalent. Although the heat of combustion of methane cannot explode in this proportion, the power of several tanks of liquefied gas is terrifying.

There was basically nothing to see at the scene.

There was more than one round of explosions at the scene, and no one caught up with the first wave, and when they went, they saw a raging fire, and then everyone tried to put out the fire.

It was a mountain village, there were no fire hydrants, and the fire trucks of those days were also very poor, and they couldn't suppress the fire at all. Later, the high temperature may have fried a few cans, and then a second round occurred, and the already unsturdy house completely collapsed.

Looking at the scene in this situation, with the technical conditions at that time, it can be said that it was a little difficult, and the province also went to someone to investigate, and finally determined that a tank leaked, and then exploded and caught fire.

There were two deceased people who could be identified at the scene, as well as some scattered... According to the transcript of Zheng Yanwu afterwards, Zheng Yanwu's family was at home at that time, and it was all gone at one time.

After reading this, Bai Song had a deeper understanding that Zheng Can might be Zheng Yanwu's child. But at the same time, he also understood that Zheng Can's uncle had a high probability of knowing something. This time it was a gas problem, not an ordinary wood fire, so there was basically no such thing as someone rescuing someone after a fire.

Bai Song analyzed two situations, one is that Zheng Can's uncle was the housekeeper of Zheng Yanwu's family, and he was playing with the little master outside the house at the time of the crime, but he escaped. But this situation is difficult to explain, because it is impossible for the housekeeper not to look for Zheng Yanwu.

The second situation is that Zheng Can's uncle knew in advance that such a tragedy had happened, but he couldn't stop it or didn't dare to stop it, so he rescued people for other purposes.

As for other bad purposes, it's hard to speculate.

Now the city has a strict emergency management and alarm mechanism for pipeline gas, which is very safe, and many places have banned the unauthorized transportation, trading of LPG tanks, but in those days, the situation was completely different.

Through the combing of the murder cases, a full eight cases that may be related have been found so far.

Three of them were related to people from printing and dyeing companies. In 1997, an ordinary employee of a printing and dyeing company was killed in a car accident on his way home.

In 1999, an operation accident occurred in a printing and dyeing company, resulting in the leakage of dozens of kilograms of highly toxic compounds, the death of one worker, and the permanent sequelae of four workers.

In 2001, Sun Yaowu's son, one of the three shareholders who went abroad, got into a verbal altercation with someone in a bar in Changhe City and was stabbed to death, and the whereabouts of the murderer are unknown.

In these three cases, the first driver has been handled, the second has punished the relevant responsible persons, and the third is unknown.

In addition to this, there are five cases that have yet to be solved.

The first and second cases occurred in 1995, when two people from the towns and villages below Changhe City were killed in the same way every other day, and after investigation, these two people have no enemies, and they have nothing in common, they are ordinary small bosses, and after investigation, these two people have not offended the same people.

The third case, which occurred in 2008, is the most recent one, and the modus operandi is somewhat similar to the above two, and the circumstances of the suspect are still unknown.

The fourth case was in 2006, in Zhangjia City, where the cause of death was cyanide poisoning, and the suspect was a friend of his, who had been on the run for eight years.

The fifth case is a car accident case in 1999, the owner of the car who caused the accident escaped, and it is still unknown who did it. The reason why this case may be related is that the deceased was one of the partners of the printing and dyeing company, and many people paid attention to this case at that time, but they were not found in the end.

Bai Song and others have done various related checks for each case, and these are the current cases.

In addition to these, we also found a homicide case in Zhuyang City, which may be related to another murder case that has been solved in Changhe City.

The modus operandi of these two cases is different, and they are not in the same city, but the deceased may have known each other, and through the concatenation of big data, the ex-wife of one of the deceased was the sister-in-law of the other deceased.

This discovery aroused the great attention of the Zhong team, because the original suspect had already eaten the gun and could not be arraigned, but there was a lot of reference between the two cases.

It can also be seen from here that Changhe City has taken great pains, in addition to the cases in this city, many cases that may be related to other urban areas have also been transferred from the provincial database.

These cases have also gone through the first round of screening, otherwise it would never have been possible to complete the investigation with just a few people from Bai Song.

All the data has been analyzed, Bai Song and the others are ready, and tomorrow, that is, Wednesday, they will officially go to talk to Zheng Can's uncle.
