Chapter 453
Huang Yuanzheng patted the old forensic doctor on the shoulder, and said with a smile, "Thank you, Uncle Xi. You go back first, and give me a copy of the detailed report after it comes out!"

The old forensic doctor nodded and left with a long sigh.

"What do you think?" Huang Yuanzheng took Wei Qing and the two to the inner room and looked at the scene of the incident.Compared with Hao Rengui's death scene of being attacked by someone, the inner room is more like a massacre. A woman is holding a daughter in a corner, her head is gone, and the bright red blood spattered on the wall is particularly conspicuous.

Wei Qing shook his head and said, "I'm not a policeman, how can I solve a case?"

"Hehe, I heard from the bureau chief that you are very capable." Huang Yuanzheng followed Wei Qing for a few days, and he naturally knew that the young man in front of him was not simple. Otherwise, a dignified criminal police captain would not ask a layman to see what clues No, at this time the three policemen who were searching for evidence in the store came over, and one of them said, "Captain Huang, your judgment is correct. We didn't find the fourth suspicious target here, but we found some on these shelves." Fingerprints, but it is estimated that those customers who came in to buy things left behind, the overlap of fingerprints is too serious, I am afraid there will be no gain."

"Hehe, I have solved many cases, and I have seen many murder cases, but this is the first time I have seen this kind of beheading murder case. Three people were killed, and even the children were not spared. This murderer should be like Hao Rengui." How much hatred is there? The money in the drawer is still there, and it can be used to repel money, so the biggest possibility is man-made conflicts!"

"Look at Hao Rengui's corpse. Just before he died, he should have stood with his back to the gate, but the murderer rushed in and cut off his head with a knife. Look at the blood stains on the ground. Two obvious lines of blood lead to the inner room, after the murderer cut off Hao Rengui's head, he walked into the inner room with the head in one hand and the murder weapon in the other, and killed their mother and daughter!"

"However, I think what Uncle Xi said is right. The murder weapon should not be an axe, but a big knife!"

Wei Qing frowned and said, "Is there a difference?"

"Of course there is a difference. Now the country has stricter controls on guns and knives, especially for those knives that are more lethal. Real-name registration is required. A murder weapon can cut off the head of an adult man together. Such a knife is not ordinary! Why do you think it is a knife?"

"Look at the calibers of the blood droplets on the two blood lines on the ground!"

"Generally, the right hand holds the knife, so the blood line on the right is very regular, it is a very thin blood line, if it is an axe, the blood line is not so thin and not so straight, only those long knives or long swords Yes, the tip of the knife or the tip of the sword is very thin, so the blood that flows down follows the person walking, and drips in a line on the ground. The blood line on the left is not continuous, and it is scattered intermittently. It should be a flow from the head Blood coming out!"

"The most important thing is, should this person be about one meter tall?"

Wei Qing exclaimed, "Can you even guess the height?"

"Guess?"

"I'm not guessing, but in the process of solving a case, a technique that is used in a wide range. A drop of blood falls from a height of one meter, forming a scattered caliber on the ground, and a drop of blood falling from a height of two meters forms a scattered caliber. The caliber and size are different. There is a complete set of calculation methods for this in investigative science. I have asked Xiao Wang to calculate it just now. If the murder weapon is an ordinary broadsword, the height of the murderer should be about 1.8 meters. The murder weapon cannot be ruled out. It is specially made, so the height of the murderer is also about 1.7 meters five!"

Mr. Legend asked: "Why is the murder weapon a big knife instead of a long sword? The blood stains dripping from the long sword can also be such a slender line of blood."

"Well. It is true that the long sword can also drip blood like this. But the key point is that the heads of the three deceased were beheaded at one time. It is easy for the long sword to kill and injure others, but it is easy to cut off the head with one sword. It should be more difficult to come down, right?" Huang Yuanzheng walked into the inner room, pointed to the blood stains on the wall, and said, "The blood stains on the wall are relatively large, which means that the cutting area of ​​the murder weapon is large, so the blood splashed on the wall Many, if it was a long sword, the blood stains on the wall wouldn't be so scattered!"

"Another point!"

"If you were a murderer and you wanted to kill the three members of this family, would you come in with a sword? The sword is too long and it's not easy to hide it! The light at night is weak, so it's easier to hide the sword, and Daddy In the morning, no matter how you disguise your sword, you will be easily spotted!"

Wei Qing nodded and said: "That's right, I really deserve to be the captain of the criminal police team!"

Then Huang Yuanzheng turned around and said: "But in fact, what I said is nonsense, and it is not valid. This street is a main road, and it is patrolled and monitored. I checked the records this morning. This morning After Hao Rengui opened the door, no one came in at all. After the heavy rain, the owner of the barber shop next to him came over and reminded Hao Rengui to put away the goods outside, so as not to get wet by the rain. case!"

Wei Qing reminded: "What if the murderer lurked into the shop last night?"

"I'm asking the police to check the video of yesterday and the day before yesterday, but I don't think I've gained much. Because Hao Rengui died outside, and their mother and daughter died in the inner room, which means that after they opened the door in the morning, there was no one in the whole store. Abnormal. If the murderer hid in advance, then there are shelves outside, there is no hiding place at all, only the room inside. Then the murderer must be the mother and daughter who were killed first, so whether Hao Rengui outside Whether it is resistance or escape, there is enough time, it is impossible that there are no traces of fighting!"

Huang Yuanzheng said with a long sigh: "So this case is not simple at all!"

Wei Qing tentatively asked: "What if it was done by ghosts and gods?"

"Hehe, ghosts and gods, are there any in this world? Even if there are, what about motives? Crimes need motives, and ghosts and gods also need motives to kill people, right?" Huang Yuanzheng shook his head, glanced at Wei Qing, and said, "Aren't you in a hurry to rush?" Are you going to the Shi Family Courtyard?"

Wei Qing was surprised to see Huang Yuanzheng, this captain is really not simple, and asked: "You also know this?"

"Hehe, the torrential rain has not stopped since dawn this morning. Don't say you people from other places, even if you are a local, you won't go out so early, right? Forget it, let's be honest, the two of you came After the ancient city of Daduhe, I have been following you secretly, knowing that you have gone to the Shi family courtyard twice!"
