The Yoshikawa Line, that is, the immense pain caused by the inability of the victim to breathe when he is strangled, will make him often desperate to break free and grab the neck, intending to grab the murder weapon and keep it away from him.

At this time, nail marks will be left on the neck, and the nails will contain evidence including fragments of the murder weapon, skin, bloodstains, etc.

And, if the victim is killed, the scratches do not go away.

The Yoshikawa Line is an important proof of homicide cases in which rope strangulation is generally considered to be a crime.

Of course, this was originally just a Japanese term, but it became popular.

When Fang Yao thought of this, he suddenly felt a huge malice from the murderer in his heart!

She immediately grabbed Wang Qiyuan's hand and carefully observed every fingernail!

Two hands, a total of ten fingernails were checked, Fang Yao's fists were clenched, and his body trembled uncontrollably: "No debris, no skin, no blood...... There is no visible staining inside the nails! ”

Qin Lanzhi's expression was also even more severe: "It's not that she died by strangulation, she died of suffocation." Before Wang Qiyuan died, she did not make any resistance. ”

Fang Yao came to a conclusion: "Wang Qiyuan, she was not strangled at all, the strangulation marks on her neck, including the damaged throat, are all the murderer's tricks!" ”

Qin Lanzhi asked, "Then you are suspicious of Zhang Huixin?" ”

Fang Yao said: "No, Zhang Huixin did not miss a single detail during the autopsy, but the wounds and strangulation marks were too obvious, so she was blinded by the real murder methods hidden in the depths." ”

Qin Lanzhi said: "Indeed, the last time Cui Yuezhi killed someone, she once thought it was a suicide. ”

Fang Yao said, "Sister Lan Zhi, it seems that it is necessary for us to seriously investigate this secret room. ”

Li Jun has been silent and allowed the two to investigate.

Anyway, there were only three people on the scene, and he was also looking forward to what kind of high opinion Fang Yao would come up with after the investigation.

Qin Lanzhi said: "At that time, I only heard the sound of metal colliding on my left, and now that I think about it, it should be the sound of the cart being brought down that did not appear yesterday." ”

Fang Yao looked at the cart: "Then let's go to the cart first." ”

So, the two came to the cart and helped it up.

Fang Yao squatted down, touched the bottom of the cart, and checked the four wheels of the cart again.

Qin Lanzhi checked the contents of the cart.

"Did you find anything?"

Fang Yao shook his head: "No, it's just a cart that can hold a lot of things, a large shopping cart, the kind that is commonly used by grandfathers and grandmothers in the community, the weight of the body is not very large, but the base is very strong." ”

Qin Lanzhi speculated: "My idea is, could it be that Wang Qiyuan was in it at that time?" ”

Wang Qiyuan?

Are you in the middle of it?

Is she hiding here?

Or rather......

Fang Yao's eyes widened again, and a new round of goosebumps appeared on his skin: "Wang Qiyuan's corpse was originally nested inside!" ”

Qin Lanzhi said: "Indeed, Fang Yao, your thoughts coincide with mine. So I checked to see if there were any signs left on the inside of the body, and unfortunately, there was nothing on the surface and no blood on the inside. ”

Fang Yao adjusted his breathing and forcibly endured the feeling of horror: "So...... What Zhang Huixin said before makes sense, there are no other external injuries, so ..... No blood will be left behind. Whew~"

Qin Lanzhi held her chin with her right hand, and after thinking deeply, she said, "Actually, there is one more thing to pay attention to, of course, what we have to do is to see if a person's body can be placed inside." ”

Fang Yao said, "Sister Lan Zhi, let's come ...... you."

Qin Lanzhi didn't say a word, and got into the interior space of the body surrounded by chemical fiber fabrics as soft shields, and sure enough, not only was she able to be completely inside, but she didn't even feel too crowded.

The capacity of the cart is large enough.

Watch as she stood up, took two steps, and jumped out of the cart.

Fang Yao said: "Now it can be determined that this car is indeed a corpse." ”

"Going back to what happened in the first place, I was sure that I really couldn't have found the body hidden in the cart at the remote Angel Gate due to sight distance."

Qin Lanzhi said: "I'm also sure that when I grabbed Zhao Ting and moved slowly, my afterglow didn't capture any 'people'. ”

Fang Yao said: "Now that the conclusion is out, if Wang Qiyuan's body 'suddenly appeared', it must be hidden in the blind spot of everyone's sight at that time - in the cart." ”

Qin Lanzhi said: "There was a strong external force that dragged Wang Qiyuan's body out of the cart and brought the cart down. ”

Fang Yao fell into contemplation again: First of all, Wang Qiyuan was indeed hiding in the cart.

Was she alive in the cart at the time, or was she dead? Now there are doubts again.

If it was that black shadow, at that speed, dragging the living Wang Qiyuan to death?

Indeed, the problem of scratches can also be explained far-fetched, and it is too late to form scratches because the external force of drag is too strong.

In an instant, Wang Qiyuan was killed alive......

Is that the explanation?

Seeing Fang Yao's solemn expression, Qin Lanzhi asked, "Fang Yao, what do you think?" ”

Fang Yao said: "Sister Lan Zhi, if you use an extremely fast and powerful external force to forcibly drag Wang Qiyuan, and then throw her out, kill her in an instant...... This situation ....."

Qin Lanzhi replied quickly: "Maybe, but Wang Qiyuan didn't die of that kind of situation." ”

Fang Yao hurriedly asked, "How can you see it?" ”

Qin Lanzhi said: "Let's simulate the trajectory of Wang Qiyuan being dragged. ”

The two of them walked a few steps to the left along the cart near the Demon Gate and against the wall, and stopped at the place where Wang Qiyuan's body was displayed.

Investigate all the way, and the place where it ends is not far from the Angel's Gate.

Qin Lanzhi said: "Connect the Western weapon rack and cart into two points and one line, and you think about it carefully." ”

Fang Yao suddenly understood: "By the way, if you are subjected to such a force, how can there be no splashing blood!" However, there was not a trace of blood along the way! ”

"Not on the ground, not on the wall, not even around the corpse!"

"The corpse that has been damaged by the tough rope in the throat has not actually splattered a lot of blood!"

"Bloodstains, it's so 'clean'! Surprisingly clean, suspiciously clean! ”

Qin Lanzhi said: "You finally understand, so don't imagine that Wang Qiyuan is still alive when she is in this secret room, don't think about it." ”

Fang Yao said: "I am now sure that Wang Qiyuan has actually died from the moment she was here. ”

The two returned to the cart again.

Qin Lanzhi said: "Maybe there are some clues around us that we missed. ”

Fang Yao first adjusted his perspective to the demon gate: "By the way, this door is closed......

Qin Lanzhi was puzzled: "Yes, is there something wrong with the door?" ”

Fang Yao's expression sank: "The door is closed, that is to say, everything that happened just now constitutes the real 'secret room killing conditions'." ”

Qin Lanzhi said: "This statement is inaccurate, how can it be a murder in a closed room?" We have already argued just now, Wang Qiyuan's state in this secret room must be a corpse. ”

Fang Yao explained: "At that time, I was blocking the door of the Angel Gate, and there were a total of four people in the entire final secret room, including Li Jun, the three of you were too late to take care of anything else, and it was impossible to manage the cart, and the Demon Gate was closed. ”

"So, isn't the corpse's series of abnormal actions just a 'secret room killing'?"

"Sorry, my statement is inaccurate, it's better to say 'Murder in the Secret Room'!"

"Wang Qiyuan's corpse was treated so cruelly again! How cunning and cruel the murderer is! ”

Qin Lanzhi thought thoughtfully: "Looking at it this way, it can only be explained that the murderer set up an ingenious mechanism in advance......"

As she spoke, she glanced at Li Jun with cold eyes and stared at Li Jun: "Or, Li Jun is the real murderer!" ”
