After the police took the package away, the squadron held another meeting to explain the package and set up a temporary shift inspection team to inspect all the supplies, personnel and vehicles entering the squadron. In addition, Qu Yangbo also planned to ask for a fire dog at the training base of the corps.

After the meeting, Ren Yi felt very tired. One person could not consume much energy. The fact that Zi Yan was free at this moment was really tired. It was just a package that made the squadron panic.

Back in the office, Ren Yi half-lying on the sofa and pondered for a long time. Now for him, it was a problem of external troubles and internal troubles. They were targeted by a criminal organization of arsonism, and the personal safety of the entire squadron was threatened. The conflict between him and Gong Yingxian was tied to a dead knot. I wonder if it could be untied.

The only thing that could comfort him slightly was that his father was at least safe, so that he had no worries.

Thinking of his father, he thought of the Gong family's arson case.

At that time, his father was the captain of the Fifth Squadron, so he should be the first person to enter the fire. This is the principle of their firefighting command. He dare not go to the place he did not dare to go, and he could not let the soldiers go. Therefore, even if he was not his father, his father would definitely be present.

Whether the door lock was damaged is a very critical evidence, but his father obviously doesn't remember it, otherwise such important details would not be mentioned. The dusty memory of ordinary people can be partially awakened, and is guided by medical devices and psychologists. However, patients with Alzheimer's disease have pathological deficiencies. Even if they do hypnosis, they dare not hold any hope.

At present, it is enough to find evidence of homicide. As long as there is evidence of homicide, the case can be restarted. Now they can only obtain some of the original information and evidence based on their positions, but if the case is restarted, they can contact all the evidence and investigate the original person involved.

This year is the last year. Once the 20-year prosecution period is over, the case will never be seen again, and Gong Yingxian will never be able to get out of it for the rest of his life, so they must find evidence.

Thinking of this, Ren Yi sat up from the sofa, walked to the desk, spread the information in the file box on the table, and studied it carefully.

If his guess is correct, then when the murderer returns to the living room to set fire, the combustion aid agent should be integrated with the combustion aid agent in the kitchen. Since gasoline will produce flowing fire and obvious burn marks on the ground, if the burn marks of the combustion aid agent are not smooth, it will be an unexplainable contradiction. But adding fuel to the fire is a very dangerous behavior and it is easy to cause fire to get on the body. If he is the murderer, what would he do?

No matter how Ren Yi thought about it, he felt that this was difficult to do.

Imagine that the kitchen has caught fire at this time and there are fires everywhere. However, no matter how gasoline flows, it is impossible to flow into the living room without a slope. Moreover, if gasoline flows from the kitchen to the living room, the burning traces will also show the direction of the flame spreading, because the location of the fire point will leave the most serious burning pit, and the spreading direction will only spread out from the fire point.

But the explosion of kitchen gas destroyed too much evidence, making the traces of the fire point less reliable, and the living room has a more obvious burning pit, making the living room more like the fire point than the kitchen.

Since the gasoline in the kitchen cannot flow to the living room, in order to make the traces of the combustion aid look smooth, you must pour the gasoline from the living room to the kitchen. As long as the time difference between the two places is not big, there will be no obvious time difference in the burning traces, which is enough to get away with it.

But isn’t you committing suicide by holding gasoline close to the fire? Adding fuel to the fire will cause a blast, and the murderer is swallowed by the fire and cannot even use the blink of an eye.

Ren Yi frowned. Could it be that his speculation was wrong from the beginning? What kind of kitchen and living room has nothing to do with, and the murderer used other methods to forge the scene?

What else are they missing?

Ren Yi looked at the information over and over again, and it passed in the afternoon.

Before dinner, the squadron received a policeman and a family's kitchen caught fire.

This is a very common police incident, especially at mealtimes. Ren Yi rarely comes up with such incidents in person, but this time he insists on leading the team.

Before getting into the car, Qu Yangbo whispered to him: "Are you a little overreacting?"

"I've always been in the squadron for this period of time. Now it's an important period. Brothers can feel at ease after I go."

"Brothers are much more stable than you think, but you, don't spread your tension to them."

Ren Yi frowned and said, "Where am I nervous?"

"You didn't show it on your face, but in your actions."

Ren Yi looked at the equipment he had already worn. It was indeed a bit abnormal for him to issue such a police officer. He hesitated for a moment whether to go.

Qu Yangbo pushed him: "Go first, let's talk about it when you come back."

They only got out of one car. On the road, Ren Yi directed the police to evacuate the entire building as soon as possible.

The fire truck drove into the community, and a group of people gathered downstairs of the unit, some watched the fun, and some were obviously residents who ran down in pajamas.

"Comrade, you guys have it." The hostess ran over, "Go and put out the fire quickly, there are gas tanks in the kitchen."

"Is there no one at home?"

"No, the whole building has been evacuated."

Ren Yi nodded: "Get two fire extinguishers and follow me upstairs."

The hostess grabbed Ren Yi and said in fear: "There is a gas tank on it, you must be careful."

Ren Yi comforted him: "Don't worry, auntie."

If it is a fire caused by a gas leak, it will have exploded long ago. Since it has not exploded, it proves that the gas valve is intact. At this time, it is burned by high temperatures and the internal pressure increases. Although there is a risk of explosion, there is still time to stop loss.

The fired kitchen was on the third floor. Ren Yi led Cui Yisheng and Ding Qing and rushed up in three or five steps. The room was already filled with smoke, so they walked towards the kitchen.

The flame on the stove was more than one meter high, and the flame was upwards, and half of the kitchen was blackened. The flame was rushing out along the ceiling, and the flame was downwards, and the top of the gas tank was already on fire.

The valve rubber sleeve was burned by fire, the pressure inside the tank increased, the tank body swayed slightly under the action of air, and the valve was making a dangerous sound.

"Damn, the valve is loose." Cui Yisheng shouted, and he and Ding Qing opened the fire extinguisher and started spraying.

This kind of squeaking sound is a precursor to the loosening of the valve and the leakage of gas. Once the gas and air are mixed, it will explode when it encounters an open flame. The most important thing at this time is to stay away from the fire source as soon as possible.

Ren Yi looked around, picked up a rag from the desk, turned on the faucet and soaked it, and directly covered it on the top of the gas tank, temporarily suppressing the flames. Then he carried the gas tank up and ran downstairs.

When he rushed out with the still-fire gas tank, the onlookers were frightened and dispersed. He put the gas tank on the ground, and a soldier carried a fire extinguisher and put out the fire in a few strokes.

Ren Yi waved his hand: "Don't be afraid, it's okay."

The fire in the kitchen was quickly put out. Cui Yisheng and Ding Qing found a clothesline and poked the kitchen ceiling open. They left after confirming that there was no smoldering in the ceiling.

"Thank you, thank you comrade firefighters." The hostess took the lead and clapped, and bursts of warm applause suddenly rang out in the community.

"Brother Firefighter is so handsome!" The two female students shouted while recording with their mobile phones.

The male student standing beside him said sourly: "It's okay, their clothes are fire-proof. If I wear that kind of clothes, I dare to go in."

"Then can you carry the gas tank?"

“Hahahahaha.”

The little soldier on the side whispered: "Is this a flame retardant suit OK? Flame retardant and fire retardant are two different things."

Listening to their conversation, Ren Yi was stunned.

He would not have taken the unintentional words of several children to heart, but what the boy said allowed him to capture something that he ignored.

Their fire fighting suits are not fire-proof, but are more flammable, and once they explode or collapse, the outcome is similar whether they wear this suit or not. However, it is completely safe to deal with ordinary fires, short flames or high temperatures.

When encountering major fires, they have real aluminum foil fireproof clothing that can withstand high temperatures of thousands of degrees. As long as they do not burn directly, they can move in the fire, but they are very bulky and generally do not wear them.

A house like the Gong family caught fire. As long as there was a set of equipment, it could be as easy as he imagined to enter and exit.

Ren Yi's expression darkened. Eighteen, no, nineteen years ago, there was no online shopping, so it was not easy to buy a set of equipment like that.

"Ren Team." Ding Qing called out, "Will we take it?"

Ren Yi said: "All checks are over?"

"The inspection has been completed, the fire has been completely extinguished." Ding Qing smiled, "I can still catch up with supper when I go back."

"Cake it."

After returning, Ren Yi sent the new idea to Gong Yingxian and asked him if there was any progress in Wang Rui's investigation and interrogation.

Later, Gong Yingxian called and said that Wang Rui's family had been found. Wang Rui was still very resistant at present. Psychological experts wanted to anti-brainwash with the cooperation of his family.

"What about the package? Have you found anything?"

"No, but we found the place where the bombs were made."

“Where is it?”

"When we arrived at the scene, we could see that they were walking in a hurry and left a lot of raw materials. These raw materials and equipment gave us many clues to trace. Just now, Sister Yan used these clues to draw the code name of the person who made the bomb from Wang Rui's mouth."

"oh?"

“'White Flame'.”

"It turns out that he is a senior member of the organization. This person is so fucking dangerous. I hope these clues can help you find him as soon as possible."

"Of course." Gong Yingxian paused, "How confident are you?"

"It's hard to say, we still lack key evidence."

"…I told you that I think there is an insider in the investigator."

"Well, have you found anything?"

"Not yet. But...those equipment should be easily obtained in the fire protection system."

Ren Yi was stunned: "You want to say, do you think there were problems in the firefighting case back then?"

"Isn't this possible?" Gong Yingxian said calmly, "This case involves much deeper than we imagined."

Emotionally, Ren Yi was a little difficult to accept such speculation, but rationally, Gong Yingxian made a point. If someone had a slut in the forgery scene and misleading investigation, it would not be surprising that this case was closed by suicide.

"I don't know, but you're right, we can't let go of any possibility."

Gong Yingxian was silent for a moment: "Your father, is it possible for you to remember the door lock?"

"I thought of this today, but he didn't mention it, so he definitely didn't remember it." Ren Yi sighed, "His memory is very strange. Sometimes he can remember an inconspicuous little thing many years ago, and sometimes he will forget what he eats for lunch. What he can remember is completely random."

"Your father's treatment plan is almost confirmed. During the treatment, I want the doctor to intervene in his memory, maybe he can remember something."

Ren Yi said: "You can try it, but as he said, his police report should remember much more than he did."
