Pang Kuan's left wrist has two 5cm long scratches, the skin is broken, they are parallel to each other, the width is very small, and the length is the same. I observed the pair of slanted scratches, they were caused by the early hours of the morning, like a scrape of metal or a stone edge that was not sharp, but it was not scratched by a fingernail.

Considering that it may have been made when he was about to be strangled to death, I believe that the scratch came from one of the murderers in front of Pang Kuan, who had a ring on his finger, and the small diamonds on the ring or metal diamond settings or pure metal sides were scratched when the other party was wrestling with the deceased.

Not only that, the murderer was scratched on his left wrist, because the two sides stood opposite each other, so this ring was worn on the right hand by one of the murderers, of course, although there is a saying "male left and female right", but the murderer wears it on the right hand can not explain the gender, after all, many women now wear the ring on the left hand, some are afraid of wear and tear with the right hand for work, and some simply like to wear it like this, for various reasons.

However, this ring (which may or may not be a diamond ring) is women's because men's rings usually don't have that variety.

In this way, when a suspect appears, we can use whether there is a ring on his hand as a reference, and there is a place next to the scratch on the ring that may not be easy to wash, and we may be able to extract bloodstains, skin tissue, and the like.

I took out my phone and took a picture of Pang Kuan's wrist, and then covered his body with a white cloth. I took off my gloves and said to Wei Qile, "I'm done." ”

Wei Qile gave a thumbs up and said: "Strong, you can see a lot of ways here, and you are worthy of being my idol's younger brother." ”

"Your idol?" I was surprised.

"Ghost Pupil Detective." Wei Qile said regretfully: "God wanted to see the dance, so he took my idol MJ away, and God lost something to find the murderer, so he took the ghost pupil detective away." Alas......"

I nodded knowingly and sighed, "I'm 108,000 miles behind my big sister." ”

"From now on, you're my idol!" Wei Qile stared at my face like a brainless fan.

I wanted to cry without tears: "Please, big brother, I was wrong, don't treat me as an idol, I don't want to be taken away." ”

"Uh......" Wei Qile scratched his head.

At this time, Wu Dafang came back, and he said with a smile: "Brother Xu, you did a good job, I took it to the forensic doctor, saying that this saliva sample can test DNA." Have you seen the corpses? What else did you find? ”

I rolled my eyes, took out my mobile phone and opened the photo and said: "This is a scratch on the deceased's wrist, which is suspected to have been scratched by the women's ring worn by one of the murderers during the death process, which can be used as a reference at the critical moment." By the way, what about the rope that strangled Pang Kuan? ”

"I'll leave this in the police office, I'll see it when I get back. We now go to the scene of the crime. Wu Dafang looked away from the screen and led me and Wei Qile out of the substation building, back to the boulevard to the butterfly park in the car.

It took forty minutes for us to reach our destination.

Wu Dafang turned the car around to the back of the butterfly park 200 meters, turned into the boulevard, drove forward for about 160 meters, and then stopped the car. In other words, the crime scene was about 40 meters from the back door of the Butterfly Park.

The scene has been cordoned off and has not yet been dismantled.

The ground is covered with floor tiles, and you can vaguely see that Pang Kuan's shoes scratched the ground when he struggled before he died.

Wu Dafang pointed to the second tree next to him, "It's hanging on the branch of this tree." The murderer should have put a rope on it first, tied a dead knot, and then hung Pang Kuan on it. ”

I looked the branches up and down and asked, "How high were Pang Kuan's feet off the ground when you got here?" ”

"Forty-six centimeters, I measured it." Wu Dafang said.

Forty-six centimeters, which is nearly half a meter, Pang Kuan's height is one meter seventy-six, plus one piece is two meters and twenty-two centimeters, so the height of the rope knotting is subtracted from the length of the skull, which is about two meters and a little.

In this way, the murderer does not need to go up the tree, he can reach out and tie the knot directly by wrapping the rope over the branch, and he can do it on tiptoe if he is a little shorter. But if you want to pick up Pang Kuan's weight and put a rope on his chin, the murderer is probably a man.

I went around to the tree again to observe, and indeed there was no sign of climbing, and the bark was intact.

"Brother Xu, did you find anything?" Wu Dafang asked.

I speculated: "During the crime, the whole process of strangling Pang Kuan to death and then hanging him from a tree was done by the man on the murderer's side, and the woman only played an auxiliary role." ”

"Does a woman buy murder?" Wu Dafang pondered.

I spread my hands and said, "Maybe the male murderer and the woman have some unusual relationship." If this case is not caused by feelings, it is a conflict of interests. After watching the scene, there is no big harvest, let's go to check Pang Kuan's circle, otherwise we won't be able to run for three days and three nights. ”

Wu nodded generously, and we got into the car together, and at this moment, I condensed my vision, and found an abnormal thing through the dense spots of light that penetrated the leaves and fell on the grass beside the road like stars blinking!

I immediately stopped and walked to the grass beside the road, I flipped a little over where my eyes had been locked before, and easily found a clasp, it was crystal clear and colorless, and there was very little dust on it, so I didn't have to think about it to know that it had fallen here not long ago. Not only that, but it also has a few bumps on its edges......

My mind moved, this was Pang Kuan's hand grabbed off the clothes of the female murderer in front of him when he was strangled, and then the button fell to the ground and rolled into the grass.

The reason why I could detect that something was wrong with the grass was because the wind blew the leaves, and the light flickered, and it was cast into this colorless button, and the light that appeared was brighter than the other spots, and the king's eye that I practiced had a strong grasping power, so I saw it.

Wu Dafang and Wei Qile looked at me like a pair of curious babies, and the former asked, "Brother Xu, what are you doing?" ”

I pinched the buttons in my fingertips and walked up to them, "This may have fallen from the murderer's clothes, the buttons are quite beautiful, so I can be more sure that there is a woman in the murderer." ”

"It's day!" Wu Dafang's eyes glared at the boss, and he said in surprise: "Even in the grass, you can find it, do you really have a pair of fiery eyes?" I remember that you were a stupid and cute hairy boy more than half a year ago, and now your superpowers have awakened? ”

Wei Qile's eyes were fiery and said: "I have decided, from now on you will be your hardcore brainless fan!" ”

I fled into the car and put the buckle in my bag. After a while, the two also came up. Wu Dafang asked, "Who should we go to check first?" ”

"Pang Kuan's wife." I said.

Wu Dafang said suspiciously: "From two days ago to last night, Pang Kuan's wife was not at home, do you suspect that this matter has something to do with her?" ”

I said while thinking about it: "For the time being, there is no clue pointing to Pang Kuan's wife, and the other party has no reason to do this. But as the person next to the deceased's pillow, he should know the life of the deceased best. ”

Wu Dafang started the car, and he smiled cheaply: "This is interesting, when you get to the deceased's house, you must hold it." ”

At first, I didn't understand what it meant, this Pang Kuan's wife was named Zhuang Wen, she was quite handsome, her skin was white, and her figure was plump enough, like a ripe peach.

But when we arrived at Pang Kuan's house and knocked on the door, her eyes seemed to have a stinger, she stared at me directly, gritted her teeth and said, "Xu Chen, my husband was really killed by you?!" ”

"What does this have to do with me?" I shook my head and said.

Zhuang Wen glared angrily and said, "Otherwise, how could Officer Wu bring you over." ”

At this moment, her youngest son pointed at me and said, "Murderer, you are the murderer of Daddy!" Pang Kuan's parents and Zhuang Wen's mother were also there, and when everyone saw the reaction of the mother and son, they all pulled out their arrows at me.

What kind of business is this......

I raised my hands and said, "If it's not the murderer, why didn't Captain Wu handcuff me?" ”

Zhuang Wen was speechless all of a sudden.

Wu Dafang finished watching the fun, and then he slowly explained: "This Officer Xu was specially invited by me to assist in investigating Pang Kuan's case, and I found three valuable clues in one morning, and Officer Xu was still sleeping in the police station last night, so ...... Don't be prejudiced against him anymore......"
