Gong Yingxian said in a deep voice: "He told me one thing that even we don't know."
"what?"
"Do you still remember how we analyzed how to set the fire and how to disguise it as a suicide method based on the structural model of my house, restored on-site photos, and evidence?"
"Remember."
"At that time, we believed that there were two fire points. The first fire point was the kitchen where a lot of evidence was missing because of the explosion, and the second fire point was the sofa in the living room that the murderer set on fire in order to fake suicide and to get himself out. Considering how the murderer The problem of entering my house and how to get out, the kitchen window has anti-theft nets, no one can enter, the murderer can only enter and exit through the front door, so it is very important whether the door lock has any signs of damage, and because of this, the first person to enter the house ... are suspicious." Gong Yingxian said while stealing a glance at Ren Yi's expression.
Ren Yi didn't care: "Continue talking."
"As long as the lock is intact, it proves that no outsider has entered my house, and that my father set the fire in the house. Well, if the lock on the living room door is good, if the murderer never used the living room the door to get in and out?"
Ren Yi frowned: "Then how do you get in? Your house only has the main entrance of the living room and... Could it be a garage? But the garage was rejected by us from the very beginning. The garage also has doors, a rolling shutter door and an entrance door. There are also traces of broken door locks, and , Didn’t you say that you have to use the remote control to close the garage door when you go out?”
"yes."
Ren Yi was a little confused: "According to what you said, you need to destroy two doors to enter, and you need to close the door with a remote control when you go out. That is much more difficult than the living room door."
"It is precisely because of this that the original investigators and we were the fastest to rule out the garage."
"Did the murderer really get in and out of the garage? How did he get in and out? Why did Bai Chicheng know?"
"The living room door of my house is a double large copper door, with a total of nine world locks, using the best B pole lock cylinder of that era. Even with professional lockpicking technology and tools, it can be opened without damaging the door lock. It also takes a quarter of an hour to half an hour, and there are people patrolling the community from time to time at night, so it is very difficult to break the lock of the living room. In contrast, although the garage has two doors, it is less difficult to enter than the living room door. The first is the outer shutter door, The door lock of the rolling shutter door is the most common lock. After a little practice, a wire can be opened without any traces. After opening, the rolling shutter door can be lifted up. The entrance door inside is an ordinary anti-theft door, and it is not difficult to open. As for whether the door has been opened by external force, I also want to know, this is the key evidence, but I searched through the investigation report, and there is only this description for the garage door—'the garage door is in good condition'."
Ren Yi was startled: "Which garage door?"
"That's right, which garage door? Does this garage door refer to a rolling shutter door or an entry door? None of the dossiers described the two doors separately. They only said that the garage door was in good condition. I don't know what the investigation report at the time was. Is it because there is a rule that the situation of each door lock must be clearly written, or because this case was arbitrarily judged to be a suicide, these details were ignored accidentally or intentionally."
"Impossible. Back then, fire investigation was still the job of the police. Although I'm not sure, how could such an important detail as the door lock be missed? Now we are doing fire investigation, and we have to carefully check the doors and windows. However, there is only one place If there is an abnormality, we will write it into the report. If there is no abnormality in the door and window locks of the whole house, then just write that there is no trace of external damage. Therefore, if the investigation report says that the garage door is intact, it is in good condition, and there is no need for special inspection. Whether the lock is complete or not is obvious at a glance, even if the investigators deliberately conceal it, it’s too obvious.”
"If they are all intact, then what Bai Chicheng said to me cannot be explained."
Ren Yi's heart tightened: "What did he say?"
"He said the killer didn't go through the living room door, he got in and out of the garage."
Ren Yi's eyes widened: "How would he know? Besides, the garage door is impossible no matter how you look at it... Wait, you just said that the garage door can be lifted as long as the lock is unlocked? Then why can it be lifted by manpower but not put down? Maybe the murderer pulled down the shutter door from the outside after he left."
Gong Yingxian shook his head: "I said at the time that the garage door cannot be lowered from the outside. I have investigated it. Although my garage door is also called a rolling door, it is not the thin rolling door that you imagine. My rolling door is made by It is composed of several long metal plates and weighs more than two hundred kilograms. When it is opened, it slides into the garage roof along the three tracks on the ceiling. It cannot be rolled up. It is more accurate to call it a lift door. Open the garage door lock, an adult man can lift it up by inertia, but when leaving, the door is on the ceiling more than two meters high, with the height and weight of an adult man, even if he steps on a ladder to reach When it comes to the rolling door, how can he pull down a door that is dozens of catties heavier than himself on the ladder?"
"The more you talk about it, the more confused I become. Don't you think this is more outrageous than the guess of entering from the living room? First of all, we don't know whether the garage entrance door has any signs of damage. Secondly, the problem of the rolling door cannot be explained. Looking at it this way Come on, it is more reasonable for the murderer to enter through the living room door."
"That's how I refuted Bai Chicheng at the time. Do you know what Bai Chicheng did?"
"what?"
"He lit Yue Xingu on fire, and then he told me that only he knows what Yue Xingu knows now, and he has evidence to prove that the murderer entered and exited through the garage door, so I must help him leave. If he is arrested, he will Can't say a word."
Ren Yi sucked in a breath of cold air.
"I've thought about all kinds of possibilities. I can no longer doubt your father in my heart, so I tried to think about it from the perspective that the living room door was intact and the murderer entered and exited through the garage door according to what Bai Chicheng said."
Ren Yi looked at Gong Yingxian, waiting for him to continue.
"The murderer entered your house through the garage door and poured accelerant on the kitchen, living room, stairs and other places. At this time, there are two possibilities. First, in order to ensure his own safety, he did not set fire at this time, but opened the kitchen. Window, leaving the garage door, returning to the ground, throwing the fire in through the kitchen window, and second, leaving the garage after he set the fire, and the kitchen window was blown open."
"And then? The two garage doors are still a problem."
"If there is a person who can take my dad's key after entering the house, enter the underground garage, put down the shutter door, and disguise the entrance door as a firefighter to destroy it."
Ren Yi stared straight at his eyes: "You..."
"The door of the living room was also damaged by external forces, but it was destroyed by firefighters as a last resort, so for the investigators, it is 'intact', this is 'damage' that does not arouse suspicion, and it is conditional' intact '."
Ren Yi was silent, he knew what Gong Yingxian was going to say next.
"Then this person will definitely not be the old captain, because as the squadron leader, your father must be the one who rushed to the front, so he was the first to break down the living room door, and the first to go upstairs to save people after entering, but he I will direct other people to go to various places to check whether there are trapped people and dangerous objects."
"You mean, the insider of the murderer may be someone from my father's squadron."
"This is a possibility, and that's what Bai Chicheng said, and he said that he has evidence to prove this and who that person is. This part of the missing information was tampered with or stolen by Zhang Wen secretly. It’s because we are afraid that we will find out the truth.”
Ren Yi's complexion became paler and paler. His father's comrades-in-arms back then were a group of uncles who watched him grow up. He had eaten every family's meal and received every family's lucky money. Making him doubt these people is not much easier than making him doubt his father. He hesitated and said: "As you said, this is only a possibility. So far, there have been three possibilities in this case. The first is the official investigation, and the second is our analysis last year. , and the third one is now, too much time has passed, and the evidence is so confusing, I am not sure about any of the guesses."
"Now we can only make a judgment after seeing the so-called evidence of Bai Chicheng, but I believe he must have something important in his hand, or Yue Xingu told him something important, otherwise, he would not be so concerned about the arson case of my house." clear."
"What about others? Did he give it to you?"
Gong Yingxian shook his head: "I locked him in one place, and I planned to starve him for a few days. When his consciousness is weak, it will be easier to interrogate him."
Ren Yi shook his head: "Just for this, you take such a big risk to help him escape? Even if it breaks the law?"
"I didn't break the law. I didn't kill Yue Xingu. I was coerced by Bai Chicheng to leave." Gong Yingxian said calmly, "Although life is a bit difficult now, in order to find out the truth, I must take risks, and, I am sure to use Bai Chicheng to catch Ziyan, Bai Chicheng knows too many secrets of Ziyan, I think Ziyan wants Bai Chicheng to die in that hotel, but there is no problem between the two of them, maybe Bai Chicheng is not enough 'Pious', he doesn't want to die, he knows he's cornered, die or get arrested, and he wants to be free."
"That's not what the police said. They said that the on-site recording was against you, the evidence found at Zhang Wen's residence was against you, and the underground parking when you left showed that you were not coerced."
Gong Yingxian narrowed his eyes: "Zi Yan tried every means to prevent us from investigating the case back then, tried to murder us, killed Zhang Minde to silence him, threatened Yue Xingu to commit crimes, framed you, after all failed, he decided to frame me. The development of the matter to this point just proves that behind Zi Yan, there is a higher and greater force helping him, or that Zi Yan is serving that person. If the case back then is investigated to the end, it will definitely touch the interests of the big man , so my father became a scapegoat."
Ren Yi had some doubts in his heart, but the amount of information he received was too much for a while, and his brain couldn't handle it: "... Then, what do you want to do next?"
"Ren Yi, you have to help me. After dark, go to a place with me first."
