Wu Yun and Wei Xiaofeng saw Liu Yi's hair between his two fingers, and asked in surprise, "This hair was left by the murderer?" ”

Liu Yi took the hair closer, observed it carefully, and said, "Judging from the length and color, it won't be the hair of the deceased Bai Yunting, it should be the hair of the murderer." After that, it's the job of the police, and you only need to do a DNA comparison of this hair to find out who the murderer is. ”

"Didn't we speculate that the murderer was Yang Guangcan? You only need to compare the DNA of this hair with Yang Guangcan's, and it is ironclad evidence! Wei Xiaofeng said with some excitement.

Wu Yun said calmly: "Don't be too happy too early, if Yang Guangcan and Bai Yunting are really boyfriend and girlfriend, then finding Yang Guangcan's hair in Bai Yunting's coat and hat does not prove the fact that Yang Guangcan killed someone, he can completely say that it may have fallen inadvertently when the two were making love." ”

Wei Xiaofeng thought for a while and said, "If you don't tell him about his relationship with Bai Yunting before, and then confess when you accuse him of murder, the police will definitely feel strange." ”

Liu Yi nodded. "Actually, it doesn't matter, according to Lokar's law of material exchange, as long as the murderer has physical contact with the victim when committing the crime, he will definitely leave traces naturally or unnaturally, and he only needs to be inspected by the police's professional inspectors, and other evidence that can prove Yang Guangcan's murder can still be found."

Wei Xiaofeng stood up and said, "Then let's go back now, right?" Call the police first, and then ask the people from the ski resort to come and protect the site. ”

"Wait a minute, take a picture and save the bottom first." Wu Yun took out the SLR camera he was carrying in his bag.

Liu Yi put the hair back into Bai Yunting's coat and hat, motioned for Wu Yun to take a picture first, and then asked Xiao Feng for a small plastic bag, and put the hair in the bag and put it in the pocket.

Then he stood up and took two steps back with Xiao Feng, giving Wu Yun enough space to take a picture of the whole body and its surroundings.

Just as Wu Yun was concentrating on taking pictures, he suddenly heard a loud shout from Liu Yi behind him, which frightened him so much that his hands shook and he almost threw the SLR on the snow.

"What people!"

Wu Yun hurriedly looked back, only to see Liu Yi and Wei Xiaofeng's faces facing the direction they came from at the same time, and their eyes were full of vigilance.

Wu Yun followed their gaze, but saw nothing but the trunk of the tree. "What's wrong?"

Liu Yi replied: "There seems to be a person there just now, who fled after hearing my shouting. ”

Wei Xiaofeng also nodded and said, "Liu Yi is right, I also saw a figure just now, but it disappeared in a flash." ”

Wu Yun's expression became solemn. "Could it be Yang Guangcan?"

"It's not." Liu Yi shook his head and said, "That person's height is obviously shorter than Yang Guangcan. ”

"Who could that be? Who else but Yang Guangcan can find this place? Wu Yun asked suspiciously.

Liu Yi took a deep breath and said with a serious expression: "Could it be that our guess is wrong?" The real murderer who killed Bai Yunting a year ago was not Yang Guangcan, but the person just now? ”

But soon, as if he had thought of something, he asked Wu Yundao: "Wait, after you climbed over the fence just now, did you wipe off the snow marks left by the skis along the way?" ”

"Nope. Ah......h

"Maybe someone found the snow marks you left the slopes and followed us all the way here." Liu Yi gritted his teeth and said, "Anyway, we have to go back now, call the police before the real murderer hears the news, and let the ski resort send someone to protect the murder scene and the body." ”

Wei Xiaofeng proposed: "What if the murderer returns here before them to dispose of the body?" Why don't we leave one of us here to protect the site? ”

"No way!" Liu Yi said categorically, "If that person was the real murderer just now, he might still be hovering around." If we go our separate ways, one side is always alone, and it is easy to be attacked by him, it is too dangerous! ”

Wu Yun nodded in agreement. "Then let's go back together, shall we? Anyway, I've already taken a photo, and Liu Yi also keeps the hair of the suspected real murderer. Even if the real murderer disposed of the body before us, the things we had in our hands would be enough for the police to open a case for investigation. ”

"Shall we now cover the corpses with snow again?" Wei Xiaofeng pointed to the body of Bai Yunting, who had been dead in the snow pit for more than a year, and asked.

Liu Yi said: "There is no need, as long as the murderer remembers this cedar, which is much taller than the other trees around, he will definitely be able to find the body, whether we want to bury the body again or not, the result is the same." And it takes a lot of time to rebury the body, and we have to race against the murderer now, and we don't have that much time. ”

Wu Yun beckoned, "Let's take off our skis, right?" The route to return to is uphill, or walking on your feet is faster. ”

Liu Yi pointed to the foot of the mountain and asked, "Why don't you slide down to the bottom of the mountain?" Isn't that a little faster? Call the police first, and then go to the staff office area at the top of the mountain to notify the search and rescue personnel. ”

"It's too dangerous." Wu Yun shook his head and said negatively while taking off his skis, "We don't know what the road conditions are like on the way down the slope, and it is likely that there will be mistakes, which is too risky." It's still going back the way you came, which will take a little more time, but at least it will be absolutely safe. ”

Liu Yi had no objection after hearing this, and obediently squatted down and took off his skis. Since Wu Yun, who has four years of skiing experience, does not dare to venture down the slope, how can he have the courage and ability to ski when he has just started skiing?

The trio quickly took off their skis and ran back along the snow trails with their skis deep and shallow. It didn't take long for them to see a clear line of footprints next to the stray snow marks on their skis.

"It looks like the guy just now chose to run back on both feet, just like us." Wu Yun said.

Liu Yi compared the size of himself and the row of footprints while running, and said, "This person's feet are so small, eighty percent of them are women." ”

Wei Xiaofeng asked slightly out of breath: "So you can rule out that person is the murderer of Bai Yunting?" ”

Liu Yi said rigorously: "No, I don't know yet. Because we just speculate that Yang Guangcan is more likely to be the murderer, but this does not mean that the murderer will not be someone else. In other words, it cannot be ruled out that the murderer is a woman, because in addition to her boyfriend, female friends are the most likely to accompany Bai Yunting to accompany her on the wild snow. And the advantage of the killing method of strangulation behind the back is that in addition to reducing the probability that the murderer will leave clues on the deceased, it is also that it can kill people who are about the same as their own strength, or even greater than their own strength. ”

Wei Xiaofeng said: "Great, if it were a woman, the footsteps should not be so fast, maybe we can catch up with her." ”

"Not necessarily." Wu Yun said not very optimistically, "Even if the other party is a woman, she has been born and raised in the Northeast for so many years, and walking on the snow is like a daily routine, and we may not be able to catch up with her." ”

"Let's not think about catching up with that person, now it's the most important thing to go back to the ski resort to call the police and find someone to go into the mountain to protect the scene and the body." Liu Yi said.

After that, in order to save their physical strength, the three of them did not speak again, and ran all the way to the southeast ski slope along the snow marks left by the skis and the series of footprints when they came. After more than 20 minutes, they finally saw the steel mesh guardrail of the ski resort, and Wu Yun hurriedly took out his mobile phone to call the police.

After calling the police, the three of them came to the bottom of the guardrail out of breath, and without taking two more breaths, they climbed the guardrail one after another and turned back into the ski resort.

Just when the three of them were about to enter the staff office area to find someone, they saw a large group of people walking out of it. Yu Xiaoyu, Zhang Yueyue, Chen Xueqi, Zhu Jie and Qi Xin, who looked anxious, walked at the forefront of those people, followed by Ji Wei, Zhao, Tian and other people who were ready to go.

Seeing Wu Yun and the other three with red faces, the anxious look on their faces disappeared, and a sense of relief began to overflow into the air.

"Yiyi!" Yu Xiaoyu screamed in surprise, and then flew into Liu Yi's arms like a returning milk swallow, "You're finally back!" You haven't been back for so long, I thought something had happened to you, and I was scared to death! ”

Liu Yi hugged her tightly, stroked her long hair affectionately, and whispered, "Don't be afraid, don't be afraid, didn't I come back intact?" How could I take such a risky risk as a person who cherishes my life, right? ”

"Then why did you leave me alone? Tell me about it. You don't know how worried I am that I can't find you all of a sudden? Yu Xiaoyu said sadly.

"I know! So I've been telling myself to come back to you in one piece. Thankfully, I did! Looking down and seeing Yu Xiaoyu a little angry, he quickly admitted his mistake, "Okay, I admit that I did something wrong in this matter, don't be angry." I promise, this is not the case! ”

The others ignored the two for the time being, and set them aside for the time being. Ji Wei opened his mouth and asked, "Reporter Wu, listen to your companions, did you really enter the snow mountain?" ”

Wu Yun smoothed his breath and admitted, "Yes. ”

"It's good that you're back, otherwise we would have gone into the mountains to find you." Ji Wei's tone suddenly became serious, "Do you know that your behavior is very dangerous? The situation in the snowy mountains is very complicated and dangerous, a year ago, a college girl left the ski resort and entered the snowy mountains without permission and disappeared, you don't know......"

Wu Yun hurriedly interrupted his preaching, and said in an urgent tone: "Let's not talk about this for now, you can quickly follow me into the mountain!" ”

"What's wrong?" Ji Wei saw that his expression suddenly became more serious than himself, and asked suspiciously.

Wu Yun said with sharp eyes: "We have found the body of the missing female college student a year ago, and we have also called the police just now, and the police will be there soon!" ”
