Cleaning agents are usually divided into organic solvents, powders and water-based types. Organic solvents, hydrocarbons, chlorinated hydrocarbons, alcohols, etc. are all flammable substances.

Not only is it flammable, but it may also be accompanied by toxicity. Once ignited, the consequences will be unimaginable.

That's why Lin Chen suspected the cleaner.

But Officer Zhou shook his head and smiled bitterly: "How is it that simple? You can listen to me first-

When the cleaning agent found that the cleaning agent had spilled, the cleaning staff told the assistant that they would go to the operating room to get special tools to deal with it. Within two minutes, three more guests came to the clinic, two men and one woman, and asked to see Xu Zijue.

Xu Zijue was resting in the room because he was beaten. The female assistant was worried about another incident and lied that Xu Zijue was not there, but the three people didn't believe it and had an argument with the assistant. Then the clinic suddenly caught fire.

Maybe the ashtray was knocked down, or maybe the cigarette butts and sparks just fell on the detergent. In short, the fire followed the traces of the detergent and burned from the front desk into the room where Xu Zijue was——”

"Does the three people know each other?" Lin Chen asked.

Officer Zhou shook his head: "After the incident, the confession was recorded, and the two were husband and wife. It is said that they happened to meet a third person in the elevator. Because they were all here to ask Xu Zijue for psychological counseling, they chatted in the elevator for a few words, but they were not considered to know each other."

"This is indeed strange." Lin Chen's thoughts were deep. "If someone hadn't caused trouble, the female assistant would not have called the cleaner. If the cleaning agent had not leaked, no matter how much the three people behind him made trouble, it would not have caused a fire in the clinic."

"Yes, coincidences are everywhere, just like a script carefully designed by someone, one by one, one by one." Officer Zhou sighed, "So this case can only be handled as an accident in the end."

"It's still wrong." Lin Chen asked again, "There should be fire extinguishers in the building. If the fire can be put out in time, Xu Zijue would not die."

Officer Zhou explained: "According to the confession of the female assistant, the three people participated in extinguishing the fire after the fire broke out, but the fire extinguisher could not be opened. Then they asked the female assistant to go to other floors to get the fire extinguisher. When the female assistant took the fire extinguisher back, they found that the three people were no longer there, the fire became bigger and bigger, and accompanied by the pungent smell, employees of other companies on the same floor were evacuating. The scene was very chaotic, and some people shouted that the gas was poisonous, and the female assistant also followed the crowd to escape from the building."

Lin Chen frowned even deeper, "The cleaning agent used in the building must be non-toxic or low-toxic products. Even if it really burns, it will not cause too much harm to the human body. The person who called it poison deliberately created chaos in case someone rescued Xu Zijue."

"It's very likely. At that time, who was shouting that the scene was poisonous, no one knew. Everyone was in danger, so how could they control others? ... And the fire extinguisher was unable to open because of nervousness, or was it really damaged, no one knew."

Officer Zhou sighed again and looked at Lin Chen: "I hope this is an accident. If it is a premeditated murder, it would be terrible."

If it is a premeditation, it means that the latter manipulated at least five people to complete this "perfect" accident!

The first person caused trouble and punched Xu Zijue several times, causing no serious injuries, and even if he was caught, it would not be sentenced.

The second person cleaned and leaked the detergent, but he did not intentionally, and took active measures after the detergent leaked and returned to the operating room to get the tools, which was only considered a dereliction of duty.

Third, the fourth and fifth ones are always quarreling, and it is hard to say who dropped the cigarette butts until now. Besides, there is no requirement for banning smoking in psychological clinics, and no one wants to bear the fire losses.

They were all wrong, but they couldn't convict anyone.

Xu Zijue was trapped in the room and burned to death.
