Yang Qiuchi squatted down and touched the child's carotid artery, which was no longer pulsating, and asked, "When did you find the child's body?" ”

"Just a moment." The old man wept.

"Who first found out?"

An old farmer next to him kowtowed: "Hui Yu master, I was the first to find out, I came back from the field with a hoe, when I passed by here, I found a child curled in the grass lying there, I also thought in my heart, whose child is this, in the winter into the grass to sleep, I walked over to call him, only to find that it was Li Laohan's son, bleeding from his nose and mouth, and he was dead." I was frightened, so I hurriedly ran to the village and called Li Laohan and them. ”

"Where did you find the child's body?" Yang Qiuchi asked.

"Right here," the old farmer pointed to a barren meadow beside him.

Yang Qiuchi walked in front of the barren grass and bent down to check it. This thatch grew on the ridge of the field, was half a man high, and had withered yellow. There was farmland all around, and I didn't see anyone on this cold day.

Yang Qiuchi carefully picked up the dead grass and found that there was a pool of blood in the grass, and there were no other suspicious items or traces.

Yang Qiuchi returned to the child's corpse, reached out and grabbed the child's chin and twisted it, and then carefully observed the clothes and pants that the child was wearing, and then carefully stripped off all the child's clothes and pants.

The child had a large gash on his forehead, and half of his face was stained red with blood; The right chest is sunken inward, and the surrounding area is bruised; The right thigh leg bone is broken, and it flips weirdly to the side, which looks scary.

Yang Qiuchi looked carefully at the wound on the child's forehead, suddenly sighed, leaned over to observe it carefully, and then reached out to grab a hair and slowly lifted it up.

Part of the hair was stained with blood from the wound, and from the part that was not stained with blood, it was golden.

Yang Qiuchi instructed Yuechan to bring a blank piece of paper.

Before leaving, Yang Qiuchi had already prepared some commonly used items for extracting evidence according to his own needs, such as white paper, large and small paper bags, cotton ball sticks, small pieces of cotton cloth, etc., and even made a few pairs of gloves for autopsy, and the middle layer was isolated with oiled paper. These things are kept by the little maid Yuechan.

Yuechan quickly brought white paper, and Yang Qiuchi wrapped the blood-stained yellow hair in white paper and put it in his arms.

After Yang Qiuchi touched the head, neck, chest, abdomen and legs of the corpse with his hands, he stood up and walked onto the road, bending down and walking forward slowly. Song Yun'er, Nangong Xiong and the others didn't know what Yang Qiuchi was doing, so they hurriedly followed.

Their convoy had already passed some distance before Yang Qiuchi called for a stop, so a long stretch of the road was empty.

After walking not far, Yang Qiuchi stopped, looked at a short piece of wood lying horizontally on the side of the road, studied it carefully for a while, and then came back and squatted down to look at the road. Song Yun'er followed up and asked, "Brother, what did you find?" ”

Yang Qiuchi pointed to the road, which was a messy string of horseshoe prints and a few lines of shallow ruts.

Song Yun'er looked at these horseshoe prints and asked with some puzzlement, "What's wrong?" This kind of horseshoe print is everywhere on the official road. ”

"Investigating a case is to find the unusual from the seemingly ordinary traces, so as to find the clues left by the criminals." Yang Qiuchi said.

"Brother, you must have found clues about criminals!" Song Yun'er said excitedly, "Who killed this child?" ”

"Hit by a carriage and killed!"

Yes? Song Yun'er exclaimed, looked back at the location of the child's corpse, and shook her head: "No, the child's corpse is so far away from the official road, no matter how fast the carriage runs, there is no way to knock the child so far." ”

"If you can't bump into it, can't you hug it?"

Yes? Song Yun'er exclaimed again, and then realized: "Brother, you mean that the person in the carriage hit the child to death, and in order to cover up the crime, he hid the body?" ”

"Clever!" Yang Qiuchi praised, "That's right. "You see, these horseshoe prints go from sparse to dense, and then there is a large mess of imprints, which are left by the handlebar stop after the carriage has hit a child in the gallop." There should be more than one horse. ”

Yang Qiuchi saw that Song Yun'er was looking at the horseshoe prints on the ground with wide eyes, and her eyes were still confused, so she said: "Of course, these horseshoe prints alone can't tell that the child was hit by the carriage and died, it must be based on the injury." Let's go and examine the child's body again. ”

Yang Qiuchi asked Nangong Xiong to pick up the short log on the side of the road, and then everyone returned to the child's corpse.

Yang Qiuchi pointed to the dent marks on the child's chest: "This is left by the trampling of the horse's hooves." Did you notice, the scar on the chest was an oval semicircular blunt trauma, which was very consistent with the horse's hoof. ”

"The horse's hooves were so hard that the child fractured his sternum, caused a lung contusion, and caused flail chest, hemothorax, pneumothorax, and possibly blunt heart damage (which would require an autopsy to prove). This should be the leading cause of death in children. ”

Yang Qiuchi pointed to the wound on the forehead of the child's corpse: "There is an inter-tissue bridge in the wound cavity of this wound, the wall is not neat, the wound is irregular, it is a laceration wound, it should be caused by the direct impact of the horse's leg, the skull has formed a depression and fracture, which can be felt with your hands, indicating that the carriage is very fast and the impact force is very strong." This head injury can lead to trauma and shock, which hastened the child's death. ”

Yang Qiuchi has a lot of professional terms, Song Yun'er and Master Jin have heard it in a fog, but it is not the first time they have heard Yang Qiuchi babble about strange words, and they are slowly getting used to it, and they even understand the general idea.

Then, Yang Qiuchi spread out the child's clothes and pants and put them on the ground, pointing to a mark on it: "This is left by the wheels of the carriage." ”

Lifting the child's broken right leg with both hands: "You can see the injury on this calf is the most telling thing." ”

"Judging from the direction of the traces, the child must have been knocked down by the horse, trampled by the horse's hooves, and then the wheel ran over the child's leg, forming a peeling wound on the leg - this injury is a kind of scar due to the traction of the wheel's rotation force, which caused the skin and subcutaneous tissue to peel off in a circular shape, forming a widespread subcutaneous hematoma."

Yang Qiuchi pointed to a small tear in the child's groin: "This kind of injury is called a stretch injury, which is due to the excessive pull of the wheel rotation power, the epidermis is torn and the dermis is exposed, forming this group of small strip-shaped cracks, which are consistent with skin wrinkles. ”

Yang Qiuchi said: "These two injuries are typical wheel crush injuries. It is difficult for other objects to form these two types of scars. ”

"Could it be that someone else pushed the cart and overwhelmed the child?"

"That's a good question," Yang Qiuchi praised, "but judging from the injury, it doesn't match." Yang Qiuchi pointed to the scar on the thigh of the child's corpse, "This kind of scar is very wide, if the wheels of the wheelbarrow are so wide, it is not necessary, and it will be very difficult to push." ”

"There is another point that can prove that it was hit by a carriage," Yang Qiuchi turned the child's clothes and pants over, and the back was covered with dust with fine sand and gravel, "You see, the place where the child's body was found was surrounded by dead grass and mud, not this kind of dust with sand and gravel, it should be left by the horse's hooves and wheels dragging the road after the child was hit." ”

Yang Qiuchi turned the child's body over and pointed to the scratches on the corpse's back, buttocks and elbows: "These scratches should be caused by the carriage dragging the child's body, which can confirm my inference just now." ”

Song Yun'er looked at Yang Qiuchi with admiration: "Brother, you are really amazing!" He turned his head to look at the empty official road and said, "I don't know which damn carriage hit and killed the child, how can I find this criminal?" ”

"Any crime leaves a trace!" Yang Qiuchi said confidently, "As long as you are careful, you can find out." ”

Song Yun'er asked in surprise: "Brother, you have already found the traces of the criminal, right?" Silver teeth bited, "I don't care if I hit the child, and I have to hide the corpse, I really don't have a surname, catch this damn criminal, and deal with him heavily!" Brother, tell me quickly, what is this criminal like? ”

"I don't know the criminal, but I know his carriage."

"Young Master Yang, you weren't at the scene, how could you know about the criminal's carriage?" A girl's voice came from behind Yang Qiuchi, and when he turned his head, he saw that it was Bai Sumei, who was dressed in plain clothes. Standing next to her was Madame White.

It turned out that Bai Sumei's mother and daughter waited for a while, but they didn't see Yang Qiuchi and them come back, and they just said that there was a murder, although Bai Sumei was afraid, but she was worried about Yang Qiuchi in her heart, so she and her mother came down to see Yang Qiuchi solve the case.

Yang Qiuchi looked at Bai Sumei and smiled slightly: "As I just said: any crime will leave traces!" He took out the white piece of paper from his bosom, unfolded it, and twisted the yellow hair: "The child's hair is black, therefore, this hair cannot be a child's, it should be left when the horse's leg hits the child's head." ”

"Yellow? Is the horse in the carriage a yellow horse? Song Yun'er reacted immediately.

Yang Qiuchi nodded: "To be precise, the first horse is a yellow horse. ”

"Is there a second horse?" Bai Sumei also asked curiously.

"Yes!" Yang Qiuchi said, "In fact, pay attention to the horse's running, the speed of the carriage is very fast, so when the front legs of the first horse hit the child's forehead, the child should be standing head-on, at this time the hind legs of the first horse are difficult to step directly on the child's chest, when the child is knocked to the ground, the back horse may step on the child's chest." ”
