Solving the case: Combining the police dog's olfactory genes at the beginning

But Luo Fei felt that the scene of the crime just now was not the first scene. According to the first villager who discovered the body of the deceased, he found the deceased when he went out to work in the fields around seven in the morning. Therefore, the time of death of the deceased was probably at night. .

The deceased ran to the fields at night, unless he was going to the toilet, but Luo Fei just took a look and found no traces of defecation or urination.

Thinking about it, Luo Fei then smelled the smell of the deceased and came to the road. Then he saw a very light black gas in the grass beside the road. Luo Fei got closer and saw a few drops of blood.

Now it is certain that the highway is the scene of the first crime. The deceased was probably attacked by the murderer here. Then the murderer took the deceased to the field and cut off the deceased's reproductive organs.

"Team Zhao, team leader, have you found anything here?" Luo Fei shouted towards Zhao Donglai and Yang Su on the other side of the crowd.

Soon Zhao Donglai and Yang Su heard the sound and came over.

"There are three drops of blood here. It looks like it was left yesterday. It was probably left when the murderer smashed the head of the deceased." Luo Fei pointed to the three drops of blood in the grass next to the road and explained to Zhao Donglai and Yang Su.

Zhao Donglai frowned, "Does that mean this is the scene of the first crime?"

"I suspect so." Luo Fei nodded.

Yang Su asked doubtfully: "If these drops of blood were the blood that the murderer dropped when he smashed the deceased's head, then the blood stains should be from here to the deceased's body, not just here."

Luo Fei had considered this point before and replied: "I just noticed that the deceased was attacked on the back of the head. After the murderer attacked the head of the deceased, there was a high probability that the deceased fell down on the spot, and it happened that he fell The blood on the deceased's head dripped onto the grass nearby, and then the murderer carried the deceased to the field to commit the second crime. At this time, the blood on the deceased's head should have dripped on the deceased's back."

"Is that really the case? Let's go and see if there is any blood on the back of the deceased." Zhao Donglai said, then turned and walked straight towards the body of the deceased.

Luo Fei and Yang Su also quickly followed Zhao Donglai.

When the three people came over, Yang Mei and other people in the technical room were inspecting the body and scene traces.

The three of them happened to see the medical examiner turn the body over and examine the back.

There was indeed a lot of blood on the purple T-shirt on the back of the deceased.

"It seems that what Luo Fei just said was right. The first crime scene should be on the other side of the highway. This is the scene where the murderer committed another crime." Zhao Donglai frowned and looked at the corpse and said softly.

Then he shouted to Yang Mei who was not far away: "Yang Mei, come here."

"What's the matter, Captain Zhao?" Yang Mei came over and asked doubtfully.

Zhao Donglai said: "Luo Fei just found a few drops of blood over there, which should be the blood of the deceased. We suspect that this is not the scene of the first crime. You and Luo Fei go there to collect the three drops of blood and investigate again by the way." Let’s see if there are any other missing traces.”

"Yes." Then Yang Mei glanced at Luo Fei in surprise, feeling that this guy was really awesome. He was the first to discover something every time.

"It's over there." Luo Fei pointed to the road, and then led Yang Mei there.

Just on the grass next to the road, Yang Mei saw the three drops of blood.

"How did you find out?" Yang Mei asked curiously. These three drops of blood were hidden in the grass. Unless you leaned down and looked carefully, you couldn't see them. So how did Luo Fei find out?

"It's nothing. I just thought the scene of the first crime should be on the highway, so I came over just now to check it out and saw it." Luo Fei said politely.

"You are really amazing. If it were anyone else, even if they knew that the highway was the scene of the first crime, they might not be able to detect the blood drops in the grass." Yang Mei really felt that Luo Fei could detect the blood drops in the grass. It's really awesome.

Luo Fei smiled and said no more. Yang Mei carefully collected three drops of blood into a vessel, and then looked around, but it was obviously impossible to find anything else.

In almost twenty minutes, the people in the technical room had completed the scene traces and autopsy work, and then the body of the deceased was taken away by the funeral home's car.

"Based on the color of the spots on the deceased's body, it can be inferred that the time of death of the deceased should be about nine hours, which is twelve o'clock last night; there are two obvious injuries on the deceased's body, one is a blow to the back of the deceased's head, which should be similar It was smashed with hard objects, and there was another area where the deceased’s reproductive organs were cut off, but the real cause of death was that the genitals were cut off and he died of excessive bleeding.”

"Because the crime scene was not protected, the murderer's shoe prints left at the scene have been completely destroyed and there is no way to collect them." When Yang Mei said this, her delicate brows also frowned. If the crime scene had not been destroyed, it would have been The murderer's shoe prints can be collected, which will increase the possibility of solving the case.

But now, because there are too many shoe prints left by the onlookers at the scene, the shoe prints left by the murderer have been completely destroyed, and there is no way to collect them.

"One more thing, Luo Fei found three drops of blood in the grass next to the road. We suspect that the side of the road is the first crime scene, and the side of the deceased's body is the second crime scene where the murderer committed the crime."

After Yang Mei finished speaking, Zhao Donglai clapped his hands and asked everyone from the criminal police team to come over. Then he said: "Based on the current situation on the scene, let's sort out our thoughts."

"First of all, who is the murderer? Is the murderer male or female? Who can tell me?"

"I'm not completely sure, but if the first crime scene is on the highway, I think the probability of the murderer being male will be greater, because the deceased was at least 130 tall and tall. A girl wants to carry such a strong person on her back. It is obviously very difficult for a boy to carry him here?" Yang Su analyzed.

"Does anyone else have anything to say? Is there anything left? Well, about the identity of the murderer, I don't know, the probability of being male is higher." Zhao Donglai said, taking out his notebook to record.

"Continue, was it an acquaintance or a stranger who committed the crime?" Zhao Donglai asked again.

"It is more likely that an acquaintance commits the crime. If a stranger appears behind him in the middle of the night, the deceased will definitely be more vigilant. However, judging from the scars on the deceased's head, the scars are just on the back of the head, which means that the deceased was attacked. At that time, there should be no defense at all. In this case, I think it is more likely that an acquaintance committed the crime." Luo Fei analyzed.

"Is there anyone else who wants to say something? No, then in this case, an acquaintance has the highest probability of committing the crime." After the record was completed, he continued: "The third point is, what do you think the murderer's motive is in this case? Vendetta. ?then what?"

"I think this case should be a vendetta, so the murderer would use such cruel methods to kill the deceased. And it is very likely that this case involves emotional entanglements, so the murderer cut off the deceased's reproductive organs." Yang Mei answered.

Luo Fei thought for a while and said: "No, this case is not a vendetta. If it is a vendetta and the murderer hates the deceased so much, then there should be other scars on the body of the deceased. It is impossible to just cut off the reproductive organs and also The most critical thing is where did the deceased’s reproductive organs go?”

"Let's think about it. The murderer knocked the deceased unconscious on the other side of the road, took him to the field, then cut off the deceased's reproductive organs and left. I think the murderer knocked the deceased unconscious and took him to the field. It's more like It’s for the reproductive organs of the deceased, so it’s understandable why we can’t find the reproductive organs of the deceased.”
