Return to 1983 and be a detective

This is definitely not because Xu Shan is suffering from delusions of being persecuted.

After all, the current situation is that Dong Chunsheng has already revealed his cards.

Xu Shan and Xiang Jinsong happened to be attacked by Xing Ergou.

The fingerprints left by Xing Ergou happened to be on the steel pipe that hit Xu Shan and the others.

Next Xing Ergou happened to die.

And as long as we investigate carefully, the feud between Xu Shan and Xing Ergou will definitely be exposed.

This move after another is perfect, every detail is perfect.

It's just that the person in this dunk, Xu Shan himself, feels quite bad.

Liang Feng suddenly stopped when he saw Xu Shan, and after thinking about it for a while, he understood Xu Shan's concerns.

He comforted Xu Shan and said, "Don't worry, I can vouch for you, and I also promise you that this case will never involve you."

Xu Shan looked at it openly and sighed: "Oh, what can I say now? Let's continue to solve the case. Let me make a long story short, Xing Ergou's height is about 1.7 meters, plus the length of his belt , he was hanging on the beam while standing, with both feet touching the ground. So if he really wanted to hang himself, he wouldn't need a stool at all.

Adding this stool means taking off your pants and farting. Isn't it unnecessary?This is the first big doubt, and the second biggest doubt is, is the ground where the hanging was done a bit too clean?After a person hangs himself, he will definitely struggle painfully, so there will definitely be traces of struggle on the beams and on the ground. As a result, except for the stool that fell to the ground, everything else in the house is very neat..."

Xu Shan's explanation made Liang Feng climb to the window again and take a look inside the room.

After he came back, he was extremely impressed: "As expected of an expert, what he said is so right. It seems that this guy was hanged and did not commit suicide."

But Su Jing still insisted on her point of view: "You said about his height, what if he jumped on his knees and hanged himself? And if he didn't struggle, does it mean that he was determined to die? There was no one else in the room except him. There is no one else, how do you explain this?"

"What you said makes sense. Next we have to solve the mystery of this secret room."

Xu Shan reached out to unbuckle his belt. This action scared Su Jing and turned her back quickly: "What do you want to do?"

"Don't get me wrong, I just want to try to open the door from the outside."

Xu Shan's belt is an armed belt from the army.This kind of thing was often used to tie pants in that era, and it could also be used to tie keys and the like.

He stuffed the armed belt into the crack of the door and tried to hang it on the door latch, but failed several times.

Liang Feng stepped forward, took the armed belt from his hand, stuffed it into the crack of the door, then lifted it and wrapped the armed belt directly around the door latch. Then he lifted it hard and the door latch was lifted. It was opened.

Xu Shan couldn't help but look at him with admiration and asked curiously: "Captain Liang, this hand is really beautiful."

"I was a scout back then, and this was all trivial." He said as he took off his armed belt and gave it back to Xu Shan.

Xu Shan quickly pushed away: "Next, please bolt the door outside."

Liang Feng tried twice and successfully bolted the door from the outside.

Then the door was opened again, and the three people officially entered the house.

Xu Shan smiled and asked Su Jing: "How's it going? Is the mystery of the secret room solved?"

Su Jing didn't expect that it would be so easy to solve this puzzle. She was convinced in her heart, but she still insisted: "What's the point? His door is too broken. It's easy to do this."

"Yes, it's easy to do this. That's the big mistake this suspect made."

As Xu Shan walked towards the room where Xing Ergou hanged himself, he carefully checked the arrangement of the furniture in the room. After entering the house, he checked the roof beam where Xing Ergou hanged himself.It was found that the roof beams were covered with dust. Except for the area covered by the belt, there were no traces of wiping.

This further confirmed his idea. Obviously, Xing Ergou committed suicide. Someone strangled him to death using the method of "carrying a dead dog on his back" and then pretended to commit suicide.This method was not easy to test in the past when criminal investigation technology was not perfect.

Xu Shan stepped forward, put Xing Ergou's body down, and laid him flat on the ground. Then he also lay down, with his back to Xing Ergou, making a gesture of "carrying a dead dog on his back."

Seeing his weird movements, Su Jing frowned, but Liang Feng was full of admiration. She watched Xu Shan finish a whole set of movements without saying a word before asking, "How was it?"

"The murderer should be a man about 1.8 meters tall. He is not only tall, but also very strong and very powerful. He strangled Xing Ergou to death with his belt. The method he used to strangle people has a common name called ' "Carrying a dead dog," that is, standing back to back with the victim, letting the rope go around the deceased's neck, holding the rope and applying force in the opposite direction..."

He gestured as he spoke.

Su Jing was stunned, but Liang Feng was thoughtful: "This move reminds me of the enemy-breaking fist taught by our reconnaissance company. It seems that there is a move similar to this."

"This shows that the murderer may have been a soldier or received equivalent training. However, by determining the height, we can narrow down the scope of finding people. After all, our Longshui County is located in the south of the Yangtze River, and such tall people are quite rare."

"Other than the murderer's height, what else can you tell?"

Xu Shan then went to check Xing Ergou's body. After looking around, he came to a conclusion: "Although I cannot infer the exact time of death from the rectal temperature, one thing can be confirmed, that is, Xing Ergou died. This morning, he was probably killed by someone else before we were attacked."

Su Jing was amused by Xu Shan's speculation: "Didn't you say that the steel pipe was stained with his fingerprints? If he died before you were attacked, how could he appear at the scene of the attack?"

Liang Feng understood Xu Shan's speculation: "So the murderer took the steel pipe with the fingerprints of the deceased and deliberately threw it at the scene of your accident, just to frame you?"

"Yes, fortunately, although the murderer can fight, he is not very precise in his work. He did not forcefully press our fingerprints on the steel pipe, but only chose to discard the steel pipe at the scene. And I know who extracted the evidence process, so I didn’t get my fingerprints on the steel pipe.”

Xu Shan was also secretly glad that if he really had to carry the steel pipe directly with his hands, he would really fall into a trap.This chain of traps is really hard to guard against.

However, Su Jing did not allow Xu Shan to rejoice for long, and reminded her: "So what? Don't people suspect that you wiped off your fingerprints on purpose? By then, you won't be able to wash them off even if you jump into the Yellow River."
