We were able to find out when the train was coming easily, which provided us with a safe environment.

The difference between this time and the last time is that the tools we brought with us were much better than the last time.

The last time we came in, Li Ming and I were just holding a small flashlight, but this time we both had high-power searchlights, which can help us see the situation inside the tunnel.

As soon as I entered, I found that there was a mark on the ground, which was a little different, so I said to them, "Old man, Xu Xiaoqian, take a look at this mark on the ground?" ”

"It's a drag mark, and it looks like the head and arms were dragged in here by the killer." The old man spoke first.

After he said this, he looked at Xu Xiaoqian, as if he was asking Xu Xiaoqian if she had any different opinions.

Xu Xiaoqian shook her head, "Why don't we take a look?" The mark of this corpse? Because it is very likely that this drag mark was also made by other units or other personnel, is it too arbitrary for us to judge that it was made by the murderer? Xu Xiaoqian said tentatively.

The old man just stretched out a hand and said to Xu Xiaoqian, "If you want to check, please go to the poop." ”

I curiously approached Xu Xiaoqian's side and whispered to him, "Do you think what this old man said is right?" ”

In fact, in my heart, I think what the old man said is right.

"Do you know why I'm asking him to help me?" I shook my head, I still really didn't know that.

Why did Xu Xiaoqian have to let this old man come with him.

Xu Xiaoqian whispered to me, "Because of this old man's age, if he is a forensic doctor of his age, he must have been practicing for decades, otherwise he would not have appeared on such an occasion, and a forensic doctor who has been practicing for decades, he has seen more corpses and crime scenes than the three of us combined, so his sensitivity is the best help for us that we can't imagine The experience is the best help for us." ”

Xu Xiaoqian's words were very reasonable, and I nodded, "Then let's go and check if that mark was left by the murderer." ”

Xu Xiaoqian nodded, and we walked to the side, but no matter how I looked, I couldn't tell the difference between what the murderer left and what others left?

Xu Xiaoqian didn't know much at a glance, so she said to the old forensic doctor, "Old man, how did you see that this was left by the murderer?" ”

The old man smiled slightly.

"You come here." The old man squatted on the side of the mark, and with his right hand, he touched it back, and found a small brush to brush off the floating soil on the mark on the ground.

At this moment, we can see why this place is said to have been left by the murderer, because there is this dark red mark under the floating earth.

I gently scooped up a dark red piece with a small shovel, put it to my fingertips, crushed it and sniffed it in my nose.

The fishy smell entered my nose, my eyes lit up, and then I stretched out my tongue and licked the dark red thing, the salty feeling had already told me that this thing should be blood, if nothing else.

Xu Xiaoqian looked at the old man behind him in surprise, and said to him, "Old man, you have already seen that this is blood, right?" ”

The old gentleman nodded.

"But why can you still see it after the layer of floating soil is added? We didn't see anything wrong. Xu Xiaoqian knew too much about forensic matters and was very interested, so she asked curiously at the old man after she found out that she didn't understand.

"Your observation and judgment are good and you are sensitive to the case, you can be called a genius in the forensic field, but I think there is one point, you are still a little weaker, that is, your experience, you deal with cases naturally not as much as mine, not to mention that this place is my home field, I know more than you, I know the land in this place very well what color the floating soil is, and under the floating soil, what kind of changes will the colored things bring to the color of the floating soil? I know too well that that's why I'm making this judgment. ”

Xu Xiaoqian nodded at the old man, it seemed that he still had too much to learn.

"The head plus the arms, the total weight is about 30 pounds, an adult man will not drag him too far, plus other body parts have also been found in the nearby mountains, then basically I can determine, the location of the murder is not far from here, and it was dragged here, let's go in and look for it, maybe the deformable mark can bring us some clues."

Hearing the old forensic doctor say this, we all nodded and walked inside, hoping that the truth would be as the old forensic doctor said, and that we would find some clues on top of this mark.

When we stood up again, the old forensic doctor frowned and looked around one of the corners, for the tunnels were narrow, and there were many ravines for the rest of the staff if they wanted to be safe.

They need to get into those ravines to avoid the train, and the wind that the train brings with it, the wind pressure on them.

At this moment we clearly saw a dragging mark on the ground, turned inside, and saw the old forensic doctor standing there motionless, so I said to them, "Is there something wrong with the old gentleman?" ”

The old forensic doctor smiled, "Of course there is something wrong, you think, if he wants to drag and throw the corpse, he can basically get here, even if he wants to go deeper, there is no need for him to hide in the depression on the side." ”

"yes, what does that mean?"

Anyway, Xu Xiaoqian suddenly clapped her hands and said to us, "Old man, I know what you mean, you mean that this person met a train when he was passing on the road, right?" ”

The old gentleman smiled at Xu Xiaoqian and nodded, "That's it." ”

Xu Xiaoqian thought about it for a while, and immediately said to me, "In this way, Zhou Zheng, you make a phone call and ask those who are still in the police station to go to the railway to check the monitoring information on the train, and see how many trains passed through here a week ago?" Which other line has monitoring information? Can you find out where the murderer is? ”

I nodded hurriedly but I didn't move, because the amount of work is a bit too large, even if there are dozens of people and so many trains, we need to look at it for a long time, plus we can't be too sure about the time of death of the deceased, but there are many trains to investigate.

As if he had seen through my inner thoughts, the old gentleman smiled.
