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 materials, personnel, and vehicles entering the squadron. In addition, Qu Yangbo planned to go to The team's training base needs a fire dog.
After the meeting, Ren Yi felt very tired. One meeting didn't consume much energy. The fact that Zi Yan was at ease at the moment was what really made him tired. It was just a package, which had already made the squadron panic.
Back in the office, Ren Yi half-lyed on the sofa and meditated for a long time. For him now, it can be regarded as external troubles and internal troubles. They were targeted by an arsonist criminal organization, and the personal safety of the entire squadron was threatened. The conflict between him and Gong Yingxian was tied up again. Can't untie.
The only thing that can slightly comfort him is that his father is at least safe, so that he has no worries.
Thinking of his father, he thought of the arson case at the Gong family.
At that time his father was the captain of the Fifth Squadron, so he should be the first person to enter the fire scene. , even if it wasn't his father, his father must be there.
Whether the door lock was damaged or not is a key piece of evidence, but his father obviously doesn't remember, otherwise it is impossible not to mention such an important detail. The dusty memories of ordinary people can be partially awakened through the guidance of medical equipment and psychologists, but patients with Alzheimer's disease have pathological memory loss. Even if they go to hypnosis, they dare not have any hope.
Right now, it is enough to find evidence of homicide. As long as there is evidence of homicide, the case can be reopened. Now they can only obtain some original materials and evidence by virtue of their positions, but if the case is reopened, they will have access to all Evidence, investigation of those involved in the original case.
This year is the last year. Once the 20-year prosecution period is over, this case will never see the light of day again, and Gong Yingxian will never 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 out the materials in the file box on the desk again, and began to study them carefully.
If his guess is correct, then when the murderer returns to the living room to set the fire, the accelerant will be mixed with the accelerant in the kitchen. Since gasoline will produce flowing fire and obvious burn marks on the ground, if the burn marks of the combustion aid are not smooth, it will be an unexplainable contradiction. But adding fuel to the fire is a very dangerous act, and it is easy to get caught up in the fire. If he were the murderer, what would he do
No matter how he thought about it, Ren Yi felt that this matter was difficult to do.
Imagine that the kitchen is on fire at this time, and there are flowing fires everywhere, but no matter how the gasoline flows, it is impossible to flow to the living room if there is no slope, and if the gasoline flows from the kitchen to the living room, the burning traces will also show The direction of flame spread, because the location of the fire point will leave the most serious burn pit, and the direction of spread will only spread outward from the fire point.
But the gas explosion in the kitchen destroyed too much evidence, making the trace of the fire point less reliable, and the living room had a more obvious burn pit, making the living room more like the fire point than the kitchen.
Since it is impossible for the gasoline in the kitchen to flow to the living room, in order to make the traces of the accelerant look smooth, gasoline must be poured all the way from the living room to the kitchen. The time difference is enough to get away with it.
But holding gasoline close to the fire source, isn't it suicide? Adding fuel to the fire would cause a flashover, and the murderer would be engulfed in flames without even blinking an eye.
Ren Yi frowned, could it be that his guess was wrong from the beginning? It has nothing to do with the kitchen or the living room. The murderer forged the scene in other ways
What else are they missing
Ren Yi looked at those materials over and over again, and the whole afternoon passed like this.
Before dinner, the squadron received a policeman, and a family's kitchen was on fire.
This is a very common police situation, especially at mealtimes. This kind of police situation is rarely done by Ren Yi himself, but this time he insisted on leading the team.
Before getting into the car, Qu Yangbo whispered to him, "Aren't you overreacting?"
"I've always been away from the squadron during this time, and now it's an important period, so my brothers can feel at ease when I go."
"The brothers are much more stable than you think, but you, don't infect them with your nervousness."
Ren Yi frowned and said, "Where do I look nervous?"
"You didn't show it on your face, you showed it in your actions."
Ren Yi looked at the equipment he had put on, and it was indeed a bit abnormal for him to go out to the police, so he hesitated for a while whether to go or not.
Qu Yangbo pushed him: "Go first, we'll talk when you come back."
They only got out of one car. On the way, Ren Yi ordered the caller to evacuate the whole building as soon as possible.
The fire truck drove into the community, and a group of people gathered downstairs in the unit, some were watching the fun, and some residents were apparently running down in their pajamas.
"Comrade, you have counted." The hostess ran over, "Go and put out the fire, there is a gas tank in the kitchen."
"Is there no one at home?"
"No, the whole building has been evacuated."
Ren Yi nodded: "Take two fire extinguishers and follow me upstairs."
The hostess grabbed Ren Yi and said in fear: "There are gas tanks on it, you must be careful."
Ren Yi comforted: "Don't worry, Auntie."
If the fire was caused by a gas leak, it would have exploded long ago. Since it did not explode, it proves that the gas valve is intact. At this time, it is roasted at high temperature and the internal pressure increases. Although there is a risk of explosion, there is still time to stop the loss.
The burning 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, and they went to the kitchen.
The flame on the stove was more than one meter high. The flame was upward, and half of the kitchen was blackened. The flame was rushing out along the ceiling. The flame was downward, and the top of the gas tank was already on fire.
The rubber sleeve of the valve was roasted by the fire, the pressure inside the tank increased, the tank body shook slightly under the action of the gas, and the valve was making a dangerous sound.
"Damn, the valve is loose." Cui Yisheng yelled, and he and Ding Qing turned on the fire extinguisher and started spraying.
This barking sound is a precursor to a loose valve and a gas leak. Once the gas mixes with air and encounters an open flame, it will definitely explode. 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, soaked it, and directly covered the top of the gas tank, temporarily suppressing the flames, then he picked up the gas tank and ran downstairs.
When he rushed out carrying the gas tank that was still on fire, the onlookers scattered in fright. He put the gas tank on the ground, and a soldier carried a fire extinguisher, and put out the fire with a few strokes.
Ren Yi waved his hand: "Everyone, don't be afraid, it's okay."
The fire in the kitchen was also quickly extinguished. Cui Yisheng and Ding Qing found a clothes rail and poked open the kitchen ceiling to make sure there was no smoldering fire in the ceiling before leaving.
"Thank you, comrade firefighters." The hostess took the lead in applauding, and bursts of warm applause erupted in the community.
"Brother firefighter is so handsome!" two female students shouted while recording with their mobile phones.
The male student standing on the side said sourly: "It's okay, their clothes are fireproof, if I wear that kind of clothes, I dare to go in."
"Then can you carry a gas tank?"
"Hahahahaha."
The little soldier on the side complained in a low voice: "Is this a flame-retardant suit, okay? Flame-retardant and fire-resistant are two different things."
Listening to their conversation, Ren Yi was stunned.
He didn't pay attention to the unintentional words of a few children, but what the boy said made him catch something that he had overlooked.
Their fire fighting uniforms are not fireproof, but they are relatively flammable, and once they explode or collapse, it will be the same if they are worn or not. However, it is completely protective against ordinary fires, short flames or high temperatures.
In the event of a major fire, they have real aluminum foil fireproof clothing, which can withstand high temperatures of thousands of degrees. As long as they are not directly burned, they can act in the fire scene, but they are very bulky and generally not worn.
If a residence like the Gong's is on fire, as long as there is a set of equipment, he can enter and exit freely as he imagined.
Ren Yi's face darkened. In eighteen, no, nineteen years ago, there was no online shopping, and it was not easy to buy a set of equipment like that.
"Team Ren." Ding Qing called out, "Shall we take it?"
Ren Yi said, "Have you checked everything?"
"The inspection is over, and the fire is completely extinguished." Ding Qing said with a smile, "Now we can go back in time for dinner."
"Take it."
After returning, Ren Yi sent Gong Yingxian his new ideas, 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 members had been found, but Wang Rui was still very resistant at present, and the psychologist would fight against brainwashing with the cooperation of his family.
"What about the package, did you find anything?"
"No, but we found out where the bomb was made."
"Where?"
"An abandoned playground outside the Sixth Ring Road. When we arrived at the scene, we could see that they left in a hurry and left a lot of raw materials. These raw materials and equipment gave us many clues that can be traced. Sister Yan just used these clues , and got the code name of the person who made the bomb out of Wang Rui's mouth."
"Oh?"
"'Bai Yan'."
"Sure enough, he is a senior member of the organization. This person is too fucking dangerous. I hope these clues can help you find him as soon as possible."
"Of course." Gong Yingxian paused, "How sure are you of what you just said?"
"It's hard to say, we still lack key evidence."
"...I told you before that I thought there was an insider among the investigators."
"Well, did you find anything?"
"Not yet. But... Those equipment should be easy to get in the fire protection system."
Ren Yi was stunned: "You mean to say that you think there were problems in the fire department in the case back then?"
"Is there no such possibility?" Gong Yingxian said calmly, "This case involves far more than we imagined."
Emotionally, it is difficult for Ren Yi to accept such a guess, but intellectually, Gong Yingxian makes sense. If there are people playing tricks on the falsified scene and misleading investigation, then this case will be hastily closed as a suicide. Strange.
"I don't know, but you're right, we can't let go of any possibility."
Gong Yingxian was silent for a while: "Your father, is it possible to remember the matter of the door lock?"
"I also thought of this today, but he didn't mention it, so he must not remember." Ren Yi sighed, "His memory is very strange, sometimes he can remember an insignificant thing many years ago, sometimes I even forget what I ate at noon, and what I can remember is completely random."
"Your father's treatment plan is almost finalized. During the treatment, I want the doctor to intervene in his memory. Maybe he can remember something."
Ren Yi said: "You can try, but as he said, his police report should be more than he remembers."
"Let's try it first."
