Rojo clearly had something to say.

"Old Su, are you sure you don't need to ask anything more?"

"Not yet."

"I really doubt that you, the captain of the criminal police, bought it, in fact, there are still many detailed questions that you haven't asked."

"Okay, Detective Luo, please teach me a lot."

Luo Qiao took the water cup handed over by his father, took a sip of water, and began to put up the score in a decent manner.

"First, haven't you noticed that the lights at the entrance of the alley in the Sunshine Community are broken? That street light has been broken for several days, is it the end of the life of that street lamp, or is it man-made? What if the offender did it for convenience? ”

"Detective Luo, what you said makes sense. Of course, we noticed this problem, we called up the only monitoring probe at the entrance of the alley of the Sunshine Community, and the probe showed that the street lamp was suddenly extinguished at 12:03 p.m. three days ago, and it seems that it should be the end of its life. ”

"So, since there is surveillance, don't you see the appearance of criminals? Where did he come from? Where did it go? Isn't it possible to find that pervert by touching the vine? ”

"Chunzi Lane, except for a monitoring probe at the entrance of the alley, the rest is the monitoring at the entrance of each community. Unfortunately, the surveillance probe that entered the alley did not find any suspicious people during that time period. In addition, because of the complex terrain of Chunzi Lane, there is an inaccessible grove behind the Sunshine Community, which is advantageous for criminals, and he can enter the grove after committing the crime, and the periphery of the grove extends in all directions, and it is indeed difficult to find his traces. And the place where Liu Meimei was killed happened to be in the blind spot of the monitoring probe, in fact, even if it was within the scope of monitoring, it was difficult to distinguish the appearance of criminals when the lights were blind at that time. ”

Su Mu is telling the truth, that grove is indeed like a maze, when I used to go to school, Luo Qiao and his friends played hide and seek in the grove, for people with a bad sense of direction, once they entered, they couldn't find the north. Once, the one Luo Qiao was caught, he was a fool and walked around the grove for a long time, Mao didn't find one, and when he realized that something was wrong and wanted to come out, he found that he was lost. When I finally found the exit and felt it, the friends were called home by their mothers one by one, and they all woke up from their naps.

"Well, I'll say the second suspicion, when I was on the edge of the trash can, I smelled something I hadn't smelled before. In any case, there is a smell of mint in the air, and it seems to smell of perfume. I never wear perfume, I don't know if it's the smell of perfume on Meimei's body. You don't know that women like them, who are said to live exquisitely, have to wear perfume before they go out. ”

"It was the smell of mint, and according to the survivor of the second case, it was a mint smell that she smelled on the offender at the time."

"Well, here's the point, since there are surviving victims, the portrait of the criminal should be descriptive."

"It's a pity that because the street lights at the scene of the crime were broken at that time, the location was relatively remote, the black lights were blinding, and the victim was frightened, so he had almost no impression of the criminal, and only remembered one thing, the criminal was wearing a rather scary white mask at that time."

"Ah, that's right. So let me say the third point, since you have watched the surveillance at the entrance of the alley, you should know that there was another person who appeared with me at the entrance of the alley at that time. ”

"You mean Zhouyu?"

"Well, I've seen this guy four times in total, and each time he's weird, and to be honest, I'm quite suspicious of him."

"We did suspect Zhou Yu, Zhou Yu lives in the Lotus Community, it stands to reason that after he separates from you, he should appear in the monitoring probe at the entrance of the Lotus Community. But a minute after he was separated from you, he reappeared on the surveillance at the entrance of the alley, and stood there for about ten minutes. Later, we asked him, and he said that it was too late, and he was worried that you were not safe as a girl, so he stood at the entrance of the alley and watched you enter the gate of the community, and then turned around and went back to his residence. The surveillance at the entrance of this lotus community showed that he was not lying, and he did not come out until 9:15 this morning after entering the community more than ten minutes later. Therefore, he does not have the time to commit the crime. ”

Luo Qiao was completely deflated and weak.

"What was the cause of Meimei's death? Can you reveal? ”

"After forensic identification, Liu Meimei's head was injured by an unknown blunt object, her face was almost disfigured, and her neck was strangled with scars, and it was finally determined that she died of suffocation."

"Didn't the criminals leave a mark on her? For example......

"Like what?"

"For example, the fingerprints of criminals, DNA, or traces of sexual assault. It stands to reason that under the conditions of modern criminal investigation technology, it is a little difficult for criminals to leave no traces at all. ”

"It is a pity that the victims of several cases were subjected to inhuman torture before their deaths, but the criminals did not leave useful traces and the modus operandi was relatively proficient, which is also the thorny point of these cases."

"How is that possible? Do criminals simply kill for the sake of killing? No motivation at all? ”

"No, the victim was a woman, and they were all molested. However, no substantial sexual acts occurred. Therefore, we conclude that the offender may have some hidden disease. ”

"Hidden disease? Which aspect? ”

Su Mu's face flushed: "That, that's ......"

Luo Dachun interjected: "Why do you ask so clearly from a girl's family?" ”

Luo Qiao smiled: "Understood, it's a male dysfunction." I can think that the murderer did it to the young girl because of a hidden disease, trying to achieve the goal of curing his hidden disease, but unfortunately it is very unsuccessful, if it doesn't work, it won't work. So he perverted and killed the victim. ”

Su Mu: "It makes sense, the police also think that there is such a possibility, but it may also be due to other reasons?" ”

Luo Qiao wondered: "Where to start?" ”

Su Mu: "This is the important part I want to tell you next, the victims seem to have one thing in common, that is, they are almost all about 23 years old, and the victims of the first case are studying in schools outside the Chinese. The other two victims were in the same school as you in high school, both of whom studied in the No. 3 Middle School, of course you know Liu Meimei, and the other survivor, Xia Tingting, is of the same level as you in high school but in different classes. Xia Tingting, do you know each other? ”

Luo Qiao shook his head: "Xia Tingting? I have no impression at all, there are 20 classes in our school, and I know all of them. What's more, all the good games I had in high school were male classmates, and female classmates couldn't play with me. ”

"It doesn't matter, what matters is that the Chinese school is not far from the third middle school, why did the victim go to both middle schools and be at the same level as you?"
