Suddenly, I remembered the person who followed us on the street before, perhaps, that person was not Xuanyi at all, nor was he the person who wanted to harm us at the hotel, but. The murderer of these corpse cases in the Black Rock Network. Suddenly, I felt a chill down my spine. At that time, I also let go of Wang Yazhuo and the little ghost and chased it myself.

Luckily. The other party did not turn the tiger away from the mountain. If Wang Yazhuo falls into the hands of the other party, it will definitely be more than lucky, because this murderer does not know Wang Yazhuo's background, even if he knows, he will not be afraid at all, and he is not even afraid of the police. How could he be afraid of Wang Jianming.

Wang Yazhuo didn't know what I was looking at with Fat Lu yet, she picked up the little ghost, walked up to us with a smile, and asked us what was wrong. Fat Lu sighed a few times. Just about to say. I just smiled and shook my head, and a word of ridicule passed. Wang Yazhuo didn't look at the photos, and she didn't know that the murderer's targets all had common characteristics.

I don't want Wang Yazhuo to know, otherwise she will definitely be worried, with her temper, if she knows that the perverted murderer may have targeted her, it would be strange not to be angry. Fat Lu glanced at me strangely, but didn't say anything in the end. It wasn't until I was alone with Lu Fatzi again that he asked me why I didn't tell Wang Yazhuo.

I replied that even if Wang Yazhuo knew, it would not be of any help to the case, and in that case, it would be better not to let one more person worry. I told Fat Lu that I would protect Wang Yazhuo, as long as I was there, it would be very difficult for the murderer to attack Wang Yazhuo.

When Lu Fatzi was talking to me, someone ran in again, and they said that they had finally extracted Qiu Lei's DNA traces from the clothes in Qiu Lei's house. Qiu Lei didn't have his own home, but after Qiu Xiao's accident, Qiu Lei hadn't gone home to sleep for a long time, and the police searched for a long time before finally finding suspected DNA traces of Qiu Lei.

Qiu Lei had a criminal record before, but he committed the crime of theft in Xiaozong, and the police at that time did not leave Qiu Lei's DNA, to be precise, at that time, DNA trace identification did not begin to be widely used. The police told us that the identification center was in the process of testing Qiu Lei's DNA and that it would soon be able to compare it with the semen DNA from several crime scenes.

Prior to this, the police did not compare the DNA at the scene with the DNA traces of Qiu Lei's parents and Qiu Xiao.

Traces, which can generally only be used as a direct identification, especially in criminal cases. Direct comparison, i.e., the DNA of the DNA subject itself, in this case, should be compared with Qiu Lei's own DNA and the semen DNA of the crime scene.

Indirect comparison, on the other hand, is generally not used as an accurate result in criminal investigations.

The so-called indirect comparison does not compare the DNA of the DNA subject itself, but in this case, the DNA of Qiu Lei's relatives is compared with the semen DNA. Because of probability, the degree of similarity between DNA between unrelated people, or even between humans and some animals, may be very high, so indirect comparison is generally not directly used in criminal investigations.

Whether it is Qiu Lei's parents, or Qiu Xiao's DNA, or the DNA of the semen at the crime scene, it cannot be directly used as evidence, but can only have a guiding role. Moreover, Qiu Xiao has been sent to the hospital for a psychiatric evaluation, and the results of the evaluation have come out, Qiu Xiao is now an incapacitated person, and the extraction of his DNA requires the consent of his guardian.

And Qiu Xiao's guardian is currently only Qiu Xiao's parents.

However, Qiu Xiao's parents themselves were heartbroken, and it took a lot of effort for the police to extract their DNA before they finally succeeded. Fortunately, the police also extracted the DNA of the suspected Qiu Lei, so that a direct comparison could be made.

I was still sitting with Fat Lu, and after dark, Fat Lu didn't think about going home from work anymore, he and I were sitting, waiting for the results of the appraisal center. DNA comparison, which can be used as evidence, also takes two to three days at the earliest, but the preliminary DNA analysis results can be released in one to two hours at the earliest, but the accuracy is not so high, but it is enough for preliminary investigation and judgment.

Finally, at eight o'clock in the evening, the people from the identification center finally arrived at the police station with the comparison results. Before Lu Fatzi opened the document, the forensic personnel told us that after a preliminary comparison, Qiu Lei's DNA was different from the semen at the crime scene.

Generally speaking, it is more difficult to identify the same, and like fingerprint comparison, the same conclusion generally requires multiple or even dozens of local features and the same overall features to be reached. The conclusion is not the same, and one or two absolutely different characteristics can be found.

Fat Lu frowned: "Didn't you also send the DNA of Qiu Lei's parents, have you compared it together, don't extract the DNA of suspected Qiu Lei, it is not Qiu Lei's at all." ”

The appraiser told Fat Lu not to worry, and opened the appraisal results to see. Lu Fatzi calmed down, opened the appraisal report and looked at it, Fat Lu scolded, and then handed the appraisal report to me.

It turned out that the experts had also compared the DNA of Qiu Lei's parents with the DNA of the suspected Qiu Lei, and had preliminarily drawn a kinship, that is, it was basically certain that what the police extracted was indeed Qiu Lei's >

In this way, the possibility that Qiu Lei is the murderer of these murders has basically been ruled out.

After Lu Fatzi sent everyone out, he asked me what I thought.

I thought about it and told Fat Lu that there are many possibilities for Qiu Lei's escape, not just because he was the murderer of these murders.

So far, we have had many kinds of speculations, each of which has no direct evidence to prove, and no direct evidence to refute it, about the person who killed Hu Yufang, the person Qiu Xiao helped in fighting for time in the morgue, and the murderer in several corpse cases are the same person, which is only the one with the most clues to corroborate and the most likely.

However, none of us can guarantee that this speculation is 100% true.

"As I said before, there may be two murderers, one forced the other to rape the corpse and eat the corpse, Qiu Lei escaped, it may be because he is the murderer who forced another person to commit the crime, so his DNA and semen DNA are naturally different." I said to Fat Lu: "This is the first possibility. ”

The second possibility, my speculation is wrong, the murderer of Hu Yufang and the murderer of these murders are not the same person at all, Qiu Lei is not the murderer of these murders, but he is the murderer of Hu Yufang, because the police did not close the case, so he was afraid and fled.

Lu Fatzi's brows furrowed even more when he heard this, these cases have become more and more complicated, not only because of the individual cases themselves, but also because of the relationship between several cases.

I paced back and forth for two steps, then turned to face Fat Lu: "There is a third possibility." ”

Fat Lu was slightly stunned, but immediately laughed: "I also thought of it, you can talk about it." ”

I didn't talk nonsense with Fat Lu again: "Qiu Lei didn't kill anyone, and he wasn't the murderer in any case, maybe someone said something to him, he was afraid of being caught by the police inexplicably, so he fled." ”

In other words, Qiu Lei is likely to have been deceived.

Qiu Lei had been in prison for a year before, so naturally he didn't want to have any more prisons. Looking for Zhuang blood.

The police have arrested Qiu Xiao, but they have not finished Hu Yufang's murderer for a long time, and Qiu Lei went to the medical university to fight Hu Yufang before Hu Yufang's death.

What's more, the police also went to Qiu Lei's parents' home one after another to look for him.

If this person is someone Qiu Lei trusts very much, then smear the police and persuade Qiu Lei to flee, so as not to be a scapegoat, Qiu Lei may go. And the person Qiu Lei trusts very much, Qiu Xiao may also know, which may be consistent with the speculation that the murderer is a very important person for Qiu Xiao.

Fat Lu snapped his fingers: "Yes, in this way, the scope of the murderer should continue to shrink." ”

Lu Fatzi asked several policemen to investigate immediately, and forced them to find out all the common acquaintances of Qiu Lei and Qiu Xiao before it gets dark tomorrow.
