Xu Jiuyan was already suspicious of Li Chongyang, and Guan Zheng had already been collecting evidence. Pen, fun, pavilion www. biquge。 info Xu Jiuyan is a simple person, everyone in her eyes is a good person, although Guan Zheng has not spent much time in the police, but he has seen far more sinister people than Xu Jiuyan. If one day there is direct evidence, then even if everyone does not want to see the most believing person go astray, the facts are the facts.

Guan Zheng hurriedly entered the trace identification office, and Lao You was leisurely eating shredded squid. Guan Zheng looked at the blank space on the table and said, "What's the situation?" Eat shredded squid? ”

Lao You handed the shredded squid to Guan Zheng and said, "Eat, this is sent by Xiaohuan, it tastes good, it's a local specialty." ”

Guan Zheng grabbed a small piece and chewed it for a long time, and finally swallowed it whole. Jia Zhenkai came in from outside and said, "Master Zheng, the report is out." ”

Guan Zheng hurriedly took it and said, "Is the thing in the fireplace transferred?" ”

Jia Zhenkai nodded and said, "You guessed right. Fireplaces can be divided into four types according to the different types of combustion. The oldest is the coal-fired type, which has been completely abandoned in Europe and the United States, and the collection and storage of combustibles are very difficult, non-closed combustion, and exhaust gas particles are formed during combustion, and they are not fully combusted. It causes pollution to the environment and harm to the human body. The first is the wood-burning fireplace, it is the mainstream product used by the owner of the single building and the villa, compared with the traditional fireplace, the modern wood-burning fireplace has been greatly improved, the use of closed combustion chamber and secondary combustion technology, and can use a new type of environmentally friendly special charcoal, low cost, high calorific value, full combustion, clean emissions, is the most natural, romantic way of heating.

The masonry fireplace is one of the most efficient in wood-burning fireplace applications, with a Russian fireplace efficiency of up to 90%, far exceeding the efficiency of any heating method. The burning temperature of the fireplace is extremely high, which can prevent the low temperature from burning to avoid all the flue gas generated and emit very little particulate matter. In the four most environmentally demanding regions in the United States, Washington, Colorado, and other areas where wood burning is prohibited, fireplaces are allowed to be used as high-efficiency heating facilities. The burning of wood does not produce any sulfide and does not emit additional carbon dioxide into nature, which is a zero carbon emission; Direct use of wood burning is at least twice as economical as electric or natural gas heating.

There is also a wood-fired pellet type, called a pellet fireplace, which is suitable for homes in areas where there is no gas supply. Wood pellets are processed by adding wood chips to accelerants. It must be operated with electricity, and pellet fuel used to have few purchase channels and high prices due to the lack of manufacturers. However, Europe has achieved the standardization of pellets, and the wood pellet standard is EN14961-2, which is produced by many supporting factories, and there are no less than ten factories in China for production and sales. The production standard of granular fireplace is EN14785-2006, and there are several domestic manufacturers of granular fireplaces produced according to this standard, such as the CPP series granule furnace produced by Zhejiang Ningbo Santa Fe Machinery Manufacturing Co., Ltd., which is more famous in the industry, and the European pellet fireplace has been more popular, the combustion efficiency of this fireplace is higher, up to more than 90%, and there is no need to add material frequently, before 2008, some states of the Federal Republic of Germany also introduced policies, and the efficiency of granular fireplaces reached more than 90% of the government subsidy of 300 euros.

Then there is the alcohol fireplace, which makes it suitable for any built environment due to the fact that the alcohol fireplace fuel is smokeless, odorless, non-toxic when burned, and does not require any fuel supply from the utility side. Because it uses a modern, renewable energy source, denatured ethanol – paste alcohol, which burns cleanly, it is virtually maintenance-free.

And this liquid fuel I'm going to talk about is gasoline. The main component of gasoline is octane, which is not completely burned to produce carbon monoxide, and carbon monoxide is toxic and explosive, so this fireplace is the source of the fire. This is consistent with the fire brigade's report on the cause of the fire. Therefore, it can ensure that the murderer does not enter the scene and Chen Xi is burned to death. ”

Guan Zheng nodded and said, "Then who bought this fuel?" ”

Jia Zhenkai depressedly took a bite of squid shreds and said, "Chen Xi bought it." ”

"He bought it himself?"

Jia Zhenkai said: "Yes, I also think it's strange, but I checked, there is no problem with this store, and Chen Xi is even more unlikely to have a problem." So it's still a complicated situation. ”

Guan Zheng put the folder in his arms, took away a large piece of squid shreds on Lao You's table, and said, "This thing is good, it's delicious." ”

Guan Zheng repeatedly looked through the file of the cremation case, and the situation was indeed very unfavorable to the defendant, but the only human witness was one-sided after all, and it is unknown how the judge would decide, if new evidence can be found to show that there is no motive or anything else between the deceased and the defendant, even if it can be delayed.

Seeing that it was time for dinner, Guan Zheng went to the hospital to deliver food to Xu Jiuyan. Xu Jiuyan was lying in the hospital, looking leisurely, but in fact, her mind was full of the facts of the case. Why did Li Chongyang leave himself? Is it a coincidence or an intentional one? Now that the witness in the case has died, can the defendant overturn the case? Xu Jiuyan glanced at the calendar on her phone, there were still two days left, could she find out the truth in these last forty-eight hours?

Looking at the big bag and small wraps carried by Guan Zheng, Xu Jiuyan pouted and was unhappy: "Ah! It's takeaway again. ”

Guan Zheng explained: "I don't have time! Let's understand. ”

Xu Jiuyan reluctantly said, "Okay then." ”

Xu Jiuyan asked while eating, "How is the case investigated?" ”

"There's still no progress, and I'm in a lot of confusion."

Xu Jiuyan joked: "There are still cases in this world that make you upset? ”

Guan Zheng smiled and said, "How is it impossible? I think it's time to revisit the case. ”

Xu Jiuyan nodded and said, "I think so." You see, this case is already suspicious, but ah, when the deadline comes, the procuratorate must apply for a public prosecution, so there is a matter of hearing. Originally, we wanted to take a gamble and use corruption to bring down Chen Xi, but now there is no proof of death, even if Chen Xi has done anything, we can't find out, and Mayor Chen Gao has no loopholes. At present, there are only two suspicious points in the case: the identity of the victim is unknown, and the testimony of the defendant's witnesses is unreliable. As long as we win one one, we have a chance to turn the tables. ”

Guan Zheng said unhurriedly: "You are right, the witness is dead, and we can only find out from the identity of the victim now." But there is one more outcome that can overturn the case. ”

"Anything else?" Xu Jiuyan thought about the problem complicated.

Guan Zheng said slowly: "Article 195 of the Criminal Procedure Law. ”
