Police Detective

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

The five people who were shareholders with Zheng Yanwu 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 people used their own money to purchase part of it. From the books, there was no problem.

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

Although the other four people are still alive, three have immigrated, retained part of their shares, and sold part of them.

The only one who is in China is Wang Zhenhua, who is not yet here. He has also sold a lot of his shares.

Currently, there are as many as 17 people holding more than 1% of the company's shares, and there are dozens of scattered small shareholders. The current situation of the company is that no one has the ability to form a rope anymore.

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

The people who know the most about this case are the seven or eight police officers who went to the scene to investigate. At that time, the approval of fire protection types was all in the public security bureau, so there was no fire responsibility certificate like today. The police were responsible for the materials on site.

Times have changed. If it were now, this kind of thing would not be possible, but before 1995, many things seemed to be not rigorous enough now.

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

Taking methane as an example, the calorific value of 1 kilogram of methane is equivalent to 13kg of TNT. Although the combustion heat of methane cannot explode at this ratio, the power of several tanks of liquefied gas is terrifying.

Basically nothing can be seen at the scene.

There were more than one round of explosions at the scene, and no one caught up with the first wave. When they arrived, they saw raging fires, and everyone tried to put out the fires at that time.

This was a villa, and there were no fire hydrants. The fire engines of that era were also very poor and could not suppress the fire at all. Later, the excessively high temperature may have fried several cans, and then a second round occurred, and the already weak house collapsed completely.

It can be said that it was a bit difficult to see the scene under such circumstances, given the technical conditions at the time. The province also conducted a special investigation, and finally determined that a tank leaked, exploded and caught fire.

There were two deceased people who could be identified at the scene, and some scattered evidence was given to Zheng Yanwu to obtain transcripts afterwards. Zheng Yanwu's family members were all at home at the time, and they were all gone at once.

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 very high probability of knowing something. Because this time it was a gas problem, not an ordinary fire caused by wood fire, so there was basically no such thing as someone rescuing people after the fire.

Bai Song analyzed that there were two situations. One was that Zheng Can's uncle was the housekeeper of Zheng Yanwu's family. He was playing with the young master outside the house when the crime occurred, but he escaped. But this situation is difficult to explain, because it is impossible for the housekeeper not to find Zheng Yanwu.

The second situation is that Zheng Can's uncle knew in advance that such a tragedy would happen, but was unable to stop it or did not dare to stop it, and rescued the person for other purposes.

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

Nowadays, cities have strict emergency management and alarm mechanisms for pipeline gas, which is very safe. Many places have banned the private transportation, sale and purchase of liquefied petroleum gas tanks, but in those days, the situation was completely different.

Through sorting out the murder cases, a total of eight cases that may be related have been found.

Three of them were related to people from printing and dyeing companies. In 1997, an ordinary employee of a printing and dyeing company was involved in a car accident on his way home and died on the spot. In an era when there were not many cars, this kind of case definitely required extra attention.

In 1999, an operating accident occurred in a printing and dyeing company, resulting in the leakage of dozens of kilograms of highly toxic compounds. One worker died and four workers were left with permanent sequelae.

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

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

In addition, five cases remain unsolved.

The first and second cases occurred in 1995, when two people from a township below Changhe City were killed in the same way a day apart. After investigation, the two people had no enemies and nothing in common. They were all ordinary small bosses. After investigation, it was found that these two people had not offended the same people.

The third case occurred in 2008, which is the most recent one. The method of committing the crime is somewhat similar to the above two, and the suspect's situation is still unclear.

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

The fifth case was a car accident in 1999. The owner of the car 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. At that time, many people paid attention to this case, but they were not found in the end.

Bai Song and others have conducted various correlation checks on each case, and this is the current situation.

In addition to these, everyone also discovered a murder case in Shuyang City, which may be related to another solved murder case in Changhe City.

The two cases had different modus operandi and were not in the same city, but the deceased may have known each other. Through the combination of big data, it was found that the ex-wife of one of the deceased was the sister-in-law of the other deceased.

This discovery attracted Team Bell's great attention, because the original suspect had already been shot and could not be interrogated, but the two cases were very useful as a reference.

It can also be seen from here that Changhe City has put a lot of effort into it. In addition to the cases in this city, it also retrieved many potentially related cases from other urban areas from the provincial database.

These cases have also gone through the first round of screening, otherwise Bai Song and a few people would never be able to complete the investigation.

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