Since the scene was discovered that day, it was surrounded by a police cordon, and when something like this happened, the business manager of the community did not dare to find someone to clean up the scene for a while, so the blood stains were still there, but they had already dried up.

Everyone appeared at the scene again, and Jiang Xu asked everyone to analyze the case according to the distribution of blood stains and the person whose DNA belonged.

Although the blood on the ground has dried up, some traces of the case can still be seen.

As soon as a few people appeared at Yang Qing's house, they saw a pool of blackened blood in the living room, which was more like blood stains because it had dried up.

Shu Qing looked very unhappy as soon as she walked into Yang Qing's house, but she still analyzed the scene of the case with everyone very seriously.

Now that she has no news of Yang Qing and no clues to find her, Shu Qing looked at the thick black blood on the ground, and kept praying in her heart that she could find clues to find Yang Qing through these bloodstains.

By the way, there are not only a pool of blood on the ground, judging from the blood stains on the ground, there are several pools of blood on the ground, but obviously there are more on the sofa, because the pool of blood is a little darker than the others, and there are also some blood stains on the sofa.

In addition to those puddles of blood on the ground, there are also some fingerprint-like blood stains, I don't know whose it is, but the distribution is very messy, and there is a curved blood stain on the ground that goes from the sofa to the door.

As soon as Qiao Jing entered the house, he took a look at the scene, he originally thought it was just a simple killing, but when he saw the scene in front of him, he couldn't help frowning.

"It seems that this is not a simple murder," Qiao Jing sighed.

"What do you say?" Jiang Xu stood beside Qiao Jing, looking at the bloodstains, and kept imagining the picture of the murderer committing the crime in his heart.

"Judging from the situation at the scene, only the living room is a mess, indicating that the murderer really moved his hand in the living room, and it may be that when Yang Qing's father was not paying attention, he moved his hand on the back of Yang Qing's father, according to the blood stains at the scene, the murderer should have moved his hand on the sofa, because there are blood stains on the sofa, and the blood stains are very similar to fountain sprays, which spray out at once, so there are a lot of messy blood stains on the sofa," Qiao Jing glanced at everyone, and with such an expression.

"Yang Qing's father may have been attacked by the murderer and wanted to resist, but he was obviously not the murderer's opponent and was injured again, and after being pushed on the sofa by the murderer, he killed a few more, so it was obvious that there were more blood stains on the sofa. ”

Qiao Jing looked at the scene of the crime, and then turned his mouth again.

"Because only in this way will the murderer succeed, and the chance of killing Yang Qing's father will be greater, and judging from the scene, he did it this way," Qiao Jing then explained his own rhetoric.

When Jiang Xu heard this, he didn't speak, but a picture appeared in his mind. Yang Qing's father came out of the room, ready to sit down but was killed by the murderer in the back, with a knife, Yang Qing's father realized that someone wanted to resist, but obviously before he could resist, he was pushed down on the sofa first, the murderer saw that he fell on the sofa, and immediately pulled out the knife, followed by another knife, Yang Qing's father's blood naturally spurted out like a fountain.

"Yang Qing's father must have dealt with the murderer, because when people's lives are threatened, they will think about staying alive, so he and the murderer, which will make the ground full of traces of their fight," Qiao Jing brought out all the psychology, and he must have really thought that the horror of the case was indeed beyond his imagination.

Jiang Xu still didn't speak, but the picture in his mind still emerged, according to Qiao Jing, then it was Yang Qing's father who broke free from the murderer's hand, and immediately had a head-on confrontation with the murderer, wanting to escape from him, but he who had fallen on the sofa was obviously not the murderer's opponent.

Calling for survival, he fought with the murderer and finally accidentally fell; The couch, but since he was already injured, the couch was all blood stains on his back.

"See this bloodstain from the sofa to the door? This may be the bloodstain left on Yang Qing's body after the murderer killed Yang Qing's father, Yang Qing's father was dead, obviously, the murderer wanted to drag him out, and those messy finger prints should be left by the murderer's hand sweeping on the ground when he dragged Yang Qing's father," Qiao Jing pointed to the long curved blood stains on the ground, and then pointed to the blood stains on the ground that were very blurry and did not look like finger prints, but they were clearly finger prints.

When Jiang Xu heard this, his brows tightened, and a picture like this appeared in his mind.

The murderer saw Yang Qing's father fall to the ground, and directly stabbed him in the stomach a few times, but obviously there were not a few knives, Yang Qing's father saw the king of Hades, but when the murderer assassinated Yang Qing's father, he covered his wounds with his hands a few times, and after the murderer saw him dead, he turned his body over, so there were several obvious palm prints on the ground, and the murderer then dragged out like Yang Qing's father.

"Obviously, the murderer was premeditated early on, and it is obvious that Yang Qing's father is not the opponent of the murderer," Qiao Jing then said a little bit of his own speculation.

"What kind of person actually made such a hand, I must avenge Yang Qing and strive to catch him as soon as possible," Shu Qing was very angry, and his tone was not only angry but also firm.

"Let's analyze the fingerprints and footprints at the scene to see if it was done by one person, and guess the height and weight of the murderer," Jiang Xu hurriedly returned to reality from his own conception of the picture, although in his picture conception, it was indeed a person who committed the crime, but who knows if someone came together with the current murderer to drag out the body of Yang Qing's father after committing the crime at that time.

Such a ruthless person, let alone comfort, Jiang Xu will definitely not let him go, and the national law is even more reluctant to let him go, but who knows if the murderer has an accomplice? Yes, then naturally you can't just catch the murderer and let go of the accomplice.

So Jiang Xu wanted to see the footprints on the scene anyway, so Jiang Xu first opened his toolbox, at this time, how could there be no high-tech when surveying the scene, right.

But after a lapse around the sofa, and a look around the door, even after looking at the crime scene, there was still no footprint.

"This is unreasonable," Jiang Xu's sad face finally unfolded, and he hung a beef face, which was still an elongated version.

"What's wrong, what's unreasonable," Su Yang asked first. But in fact, after hearing Jiang Xu's words, everyone looked at him together.

"There is no trace of Yang Qing at the scene," Jiang Xu glanced at everyone and said this answer that made everyone very curious.
