Lao Zhang and I returned to the office, I stuck my head out of the office, and after making sure that there was no one around, I locked the door of the office tightly, and then began to take out the information that Comrade Jiang Dinghai gave us.

Lao Zhang and I sat on the sofa, I took out a knife, and gently ripped open the place where the file bag was sealed with glue, carefully, for fear of breaking the important things inside.

I took out all the information, there were seven sheets in total, two of which were an analysis of the means of committing the crime, which were densely written, and I looked very carefully at a glance; One is an analysis of the tools used to commit the crime, with sketches drawn on it for us to identify; There are three sheets of analysis of three cases, six victims, one by one; Another part is a general analysis of the situation of the case.

Lao Zhang and I first came up with an analysis of the six victims in three cases, and it was written that the first of these six victims, that is, Zhou Xing and Wang Zihan, had sex before they were killed.

I showed Lao Zhang this point, "Lao Zhang, look here, Jiang Dinghai's report says that Zhou Xing and Wang Zihan had sex before they died, and there were male sperm in their bodies. ”

"Bring it, I'll take a look!" Lao Zhang stuck his head over and said in disbelief, "Aren't the two of them gay?" How can there be male sperm! ”

"That's the problem!" I said to Lao Zhang, "If they are willing to do so, that is, both of them were raped before they died?" ”

"Look at what it says is the same male's sperm?" Lao Zhang's eyes widened at first, and then he pointed to the report sheet in my hand and said.

I nodded, buried my head and continued to look at the report in my hand, looking at it carefully, looking at it seriously, looking at it word for word, "Wow! I screamed in surprise.

"What's the matter?" Lao Zhang saw me casually, and I pointed to the line on the report sheet in my hand and showed it to him.

It reads: After examination, it was found that the two victims were carrying the sperm of the same male!

"Whose will that be?" Lao Zhang was very surprised, "Could it be Zhang Xinzhi?" ”

"I think this possibility is very small, first of all, when Zhang Xinzhi talked about the two of them, he didn't mention this matter, and Zhang Xinzhi admitted that he just beat the two of them! There is no need for her to hide that she raped Zhou Xing and Wang Zihan! I explained this matter to Lao Zhang, I think Zhang Xinzhi should rule out this possibility, he has explained so many things truthfully, there is no need to hide this matter, I touched my chin, while thinking, I said to Lao Zhang, "I think this matter may be strange!" ”

"He hasn't said anything about it before? It seems that he is really suspicious! Lao Zhang paused for a moment, and then said to me, in a very disappointed tone, "Why did he do that?" ”

I put my hand on his shoulder, I felt the same as him, after all, I have been a colleague for so long, after all, I thought he was a talent before, and now I feel very sorry to use my energy in those places, "But everything is understood, and our answer is out!" "This sentence of mine is not only to comfort Lao Zhang, but also to comfort himself, maybe he has some trouble!

Then Lao Zhang and I continued to read the report that Ding Hai asked us to give us, and the next thing I saw was the report of Li Xiao and Shang Zhi.

The report of the two of them is that they were fatally injured, not as written in the previous report, they were injured and unconscious, but they should have been fainted by something first, and then they were fatally injured, there was nothing abnormal in the body, and it was possible that time had passed too long, and some of the remaining things in the body could not be detected.

This is not very big from the previous forensic report, and the two reports can be compared for reference.

In the third report, the two female victims, when they died, their throats were black, they should have been poisoned, and some toxins were also found in their bodies, which were fatal, so the fatal injuries were not caused by heavy damage to the temples, but because they were poisoned.

In the third report, he also wrote such a sentence, when the two female victims died, the emotions were indeed at a time of high excitement, so it cannot be ruled out that the reason for taking drugs may be that they took drugs excessively, which caused their own death, and it has nothing to do with the temples.

The third report is completely inconsistent with what the forensic doctor said before, and I am more inclined to the report that Jiang Dinghai said.

Just like the forensic doctor said before, these two people died unconscious, I don't believe his statement, and Jiang Dinghai also reminded me before that it is impossible for a person to be unconscious before his life is in danger.

Then we looked at the crime tool, from what the forensic doctor said before, his crime tool was something similar to a target, but the head of this target was something similar to rubber, and he told us that the crime tool in these three cases was exactly the same.

This is not the case with Jiang Dinghai's test results, which read:

In the first case, the two victims died of suffocation, although they suffered different degrees of physical injuries, but they did not die, and then combined with the fact that the two victims were found in the river, we do not rule out that the two victims were drowned.

In the second case, the two victims did not suffer any extradermal injuries, and there was no abnormality in their bodies, so we do not rule out that the two victims may have been killed by someone close to them, or they may have been people they believed in very much, and the reason for the death of the two victims was a severe injury to the temple. In this case, the previous forensic analysis was exactly the same.

Then in the third case, before the death of the two victims, there was a state of extreme euphoria, it is possible that * and psychostinotic drugs were used, and the two of them took a large amount of this drug, which may have been overused, causing death, in addition, these two people are indeed homosexual, which can be seen from some hormones in their bodies.

Therefore, in the end, the conclusion is: These three cases may not have been committed by the same person, because from the perspective of the means and habits of committing the crime, there are very big discrepancies, but it is not very clear whether the murderers of these three cases know each other?
