"I remember that day very clearly, ten years have passed, but it seems to have happened yesterday. Father An recalled the police situation that day, his face was serious, and his tone was low.

"When we arrived, the firefighters had already extinguished the fire, and the house was filled with a pungent odor, a disgusting smell. ”

"The first floor is the old man's bedroom, and the mother sleeps on the second floor with her two children. The fire started on the first floor, in the middle of the night, and the old man was still asleep. When we arrived, according to the reasoning at the scene, the two old men were lying on the bed, first choked on the smoke, and then burned alive. ”

"The situation on the second floor is even more tragic, the windows upstairs are equipped with solid wood window rods, people can't jump out, trapped by the fire, the mother hugged the two children, protected in her arms, hid on the balcony, and did not escape the fate of being engulfed by the fire. ”

Yang Fei was shocked when he heard this, and asked: "It stands to reason that there is always a process from the occurrence of the fire to the time it grows, the old man is on the first floor, his movements are slow, and he can't dodge it, but it's okay to say, did the flames reach the second floor so quickly?

Father An said: "The top floor of an old-fashioned residential building is not a bungalow, but a tiled house. We asked the residents of the neighborhood, and when they went out to look, there was a fire everywhere in the building. The neighbors were so busy isolating their homes that they didn't have time to put out the fires in his house. In fact, a fire of this size, unless a professional firefighter, is a drop in the bucket and will not work. ”

Yang Fei said: "What about the cause of the fire?

"Checked. "Father Ann said, "Fire accidents caused by aging circuits. ”

Yang Fei said: "It's incredible, normally speaking, such a fire accident, casualties can definitely be avoided." ”

Father An said: "We also thought it was too strange at the time, why was the whole family burned? The forensic doctor conducted an autopsy and determined that the family of five died in the fire, ruling out the cause of his homicide. In fact, the number of fire casualties is actually very large, thousands of people die in fires in China every year, and more than 70,000 people die in fires every year in the world. ”

Yang Fei was silent.

Father An said: "When really facing the fire, people are most likely to panic, and they wake up in their sleep, and they are the six gods without masters, and in the face of disasters, we are not as strong as we imagined." Therefore, the usual fire escape drills seem useless, but they are very necessary. ”

Yang Fei asked, "Is there any evidence that the fire was man-made?"

Father An said: "With the level of criminal investigation technology at that time, we can only conclude that the circuit is aging and catching fire. The law of fire shows that it is impossible to burn all the objects at the same time when combustibles catch fire. The fire always burns from one point to another, thus forming the direction of the spread of the fire and the traces of burning, and the starting point of this spreading direction is the ignition point. ”

Yang Fei nodded in agreement.

He grew up in a police family, and he has heard a lot about this basic principle of judging the point of fire.

Because the fire burns at different times, there will be a difference in the severity of the fire, and the difference between the heated surface and the non-heated surface will be formed after burning, which not only reflects the order of the fire spread, but also shows the direction of the fire propagation.

Therefore, the order of the severity of the fire and the direction of the heating surface are the most typical traces of fire spread, which are used as an important basis for analyzing and determining the fire point in the fire scene investigation.

Ann's father said that the fire point identified at that time was near the power supply.

Yang Fei asked, "Who called the police?"

Father An said: "It's the male owner of this house, and he told us that he suspected that someone deliberately set the fire." But after we investigated, we didn't find any suspicious traces. We also investigated the man, but he had alibi evidence, and he was hospitalized for an acute appendectomy that day, and he escaped the catastrophe. Both the doctors and nurses can attest that he has not left the hospital for 48 hours. ”

Yang Fei sighed, thinking that Lao Yan was really fatal, an acute appendicitis, but it saved his life!

Ten years have passed since the fire, but the hurdle in Lao Yan's heart can never be overcome.

Yang Fei and An's father talked about coming home very late.

An Ran sent him out and asked, "Why did you pay attention to the fire ten years ago?"

Yang Fei told the story of Lao Yan.

An Ran said: "He doesn't have direct evidence, otherwise he would have sued a long time ago." ”

Yang Fei said: "Yes, a fire burned all the evidence!"

An Ran said: "The biggest suspicion in this case is that the competitor has the research results of Lao Yan. ”

Yang Fei said: "Although his competitors also have his research and development results, it cannot be said that the other party stole from his factory, after all, everything in the factory was destroyed by fire, and competitors can say that this is their own research and development." Since the opponent wants to do bad things, he will definitely leave a way out in advance. ”

An Ran said: "Yes, research results are such a thing, this is also the most difficult to judge the case." ”

Yang Fei said: "Although I know that this is the biggest suspicion, I can't find a flaw!"

An Ran said: "Do you want to investigate this case?"

Yang Fei shook his head: "I don't understand." Unless the person pleads guilty. ”

An Ran said: "Don't think about it, go back and rest early." By the way, I heard that you broke up with Su Tong?"

Yang Fei coughed lightly and said with a smile: "It's just awkward, two people are together, and they often make awkward troubles, the so-called isn't it that enemies don't get together!"

An Ran said: "Yes? When I was in Peach Blossom Village, I heard Su Tong's mother say that you have broken up! If the two of you really can't get along, let go as soon as possible, it will be a good thing for you and her." Isn't it?"

Yang Fei felt her blazing gaze, couldn't help but turn his face away, and said, "Thank you for your concern." I went back. ”

An Ran grabbed his hand and said, "Yang Fei, let's try to date, okay?"

Yang Fei's heart suddenly moved, how much courage did it take to make a woman say such a thing?

He was looking for words, how to say it, so as not to hurt her heart and not damage this precious friendship between the two?

"When I'm my girlfriend, it's dangerous. Yang Fei smiled lightly, "Do you know why Su Tong left me? Because when she was with me, she encountered the danger of kidnapping several times. The struggle in the shopping mall is too dangerous, and the two fires that Lao Yan encountered are proof of this! You should find someone with a stable job, and this is better. ”

"I'm not afraid. An Ran held his hand and didn't let go, "Because I am a policeman, I can not only protect myself, but also protect you." ”

Yang Fei pointed to her building: "You're not afraid, I'm afraid." I don't want to see this house on fire for no reason because of me, I don't want to see you turn into grease one day because of me......"

"Excuses! Business wars are not as terrifying as you say. Lao Yan encountered only individual incidents. If you want to say that, which profession is not dangerous? We who are policemen are the most dangerous! Don't make excuses, for your sake, don't say burn to oil residue, even if it turns to ashes, I am willing!"
