Chen Ziyan nodded and silently remembered that face in his heart.

By the time they returned to the crime scene, Liu Xuan and Qin Siyu had already looked at all the clues at the scene, even the fingerprints on the table.

"There are indeed women's fingerprints in this house, but because they are relatively faint, it is possible that a woman came here a long time ago."

Qin Siyu spoke after seeing Chen Ziyan come in, and also took Chen Ziyan to the corpse.

The body had not been disposed of, it was just covered with a layer of cloth.

"Similarly, traces of genital removal were also found."

Qin Siyu took a look at the front of the corpse, especially the front part of the lower body, which was somewhat bloody.

Chen Ziyan also took a look, but quickly looked away.

"The method of committing the crime is exactly the same as the previous two crimes, and there was also a fierce struggle in front of the deceased. However, in the end, the fatal injury was not the stab wound in the abdomen, but the artery injury in the leg." Qin Siyu pointed to the body,

He opened his mouth and looked at the doubtful points he had written down in his notebook.

"In addition to this, the artery in the leg was deeply injured, and judging from the amount of blood flowing out, the deceased should have died of ischemia, but there were also traces of strangulation on the neck. There is currently no way to judge.

Is the murderer male or female?"

Qin Siyu walked around the room again to confirm every clue found.

"And another thing that needs to be noted is that there was not a single hair left in the whole room that did not belong to the deceased. In other words, the murderer either cleaned the scene when committing the crime, or this was a premeditated crime plan.

"

If it was just an impulsive murder, there would definitely be many traces of the murderer left at the scene.

While talking, Zhang Chuge suddenly rushed in and walked in front of everyone.

"I just went to talk to the neighbors. Whether it was upstairs or downstairs, they all said they didn't hear any quarrels."

"At the same time, the door lock at the door has not been picked, which means that this is a case where the deceased invited the murderer into the house, but was eventually killed by the murderer."

Chen Ziyan took a look when he entered the house earlier, and now he said very firmly.

Liu Xuan nodded.

He glanced at Chen Ziyan with admiration, and then moved his gaze to Qin Siyu.

The autopsy report of the body has also been released.

The results of this autopsy report are similar to those of the previous three murder cases.

"But one thing that needs to be noted is that when the murderer cut off the deceased's genitals this time, he used a somewhat unfamiliar technique. At least from the traces left, it can be seen that the cutting was done for a long time, and there was also a test knife.

hurt."

The so-called test cut means to try it out and make a pre-cut before cutting.

This usually occurs in victims who commit suicide by cutting their wrists.

After all, you have to try the strength and the direction of the knife. Moreover, since it is suicide, it is not easy to be cruel at first.

After Qin Siyu finished speaking, he projected the photographed autopsy results on the PPT.

Of course, we only focused on the location where the lower body was cut.

"Especially in this area, it was cut several times. The cut mark on the piece of meat here is not very smooth, which means that the murderer cut it several times before cutting off the genitals."

Qin Siyu pointed to the picture on the big screen and said.

The photo displayed on the big screen looked bloody and bloody at the moment, making it unbearable to look at, but Chen Ziyan still looked at it very seriously.

"Are there any other problems found besides this?"

Chen Ziyan looked at the autopsy report again and then asked.

"No traces that may have been left by the murderer were found on the body, including no lipstick marks on the lips."

"That is to say, either there was no close contact between the two, or it was wiped away deliberately by the murderer."

Zhang Chuge added something on the side.

"That's right, but if it was really wiped away by the murderer, there should be clues left. But since there are no clues, it means there is a high probability that the two people have not experienced close contact. But in the first

The corpse of a murder case clearly left traces of lipstick and some cosmetics, which means that the murderer is most likely a woman, but this time the corpse did not leave any traces of close contact. Do you think a man and a woman were killed?

If a woman met in this house, wouldn't she have some relatively intimate contact at the beginning of the meeting?"

Chen Ziyan took a sharp look around.

But Liu Xuan sat in the corner with a calm face, still holding the autopsy report in his hand, then sighed softly, stood up and walked out of the door.

"Maybe the killer is actually a man."

Zhang Chuge nodded, but he still felt strange in his heart.

"In other words, we were all misled before. The murderer may be a male. As for the traces of cosmetics found on the deceased, it is possible that the murderer is actually a transvestite?"

After saying that, Zhang Chuge suddenly had a blush on his cheeks.

"It is possible, but don't limit the gender of the murderer to male or female just yet."

…

Qin Siyu stood in front of Liu Xuan.

"In addition, there is another point that needs attention in the report of this incident. The fourth deceased has been found, but his family is unwilling to come, or even take the body back."

"In other words, the relationship between the deceased and his family was not good. Maybe there were other things that caused it?"

Liu Xuan raised his eyebrows slightly and continued to lie on the bed.

Zhang Chuge nodded and said yes.

"From the very beginning, when we found out the identity of the deceased, we found that his household registration, work and permanent residence were all local. Logically speaking, his family should be here as well, but the deceased lived alone and had already lived in this place.

I have been living alone for more than a year, and before that I was living alone in another house."

"Besides, I think it might be wrong for Chen Ziyan not to set limits for himself..."

"That's exactly what I think, because it may be easier to get twice the result with half the effort by first defining the murderer as a gender and then conducting verification on it."
