"Hahaha, don't be so serious, I'm not a policeman, how can it be the same as an interrogation. ”

"I don't want Zhiming's death to be so unclear, Luo Chuan, if you can, I really hope you can catch the murderer. Lin Baizhou said in a deep voice.

"I will, although I have a holiday with him, but it is just a petty fight, and this murderer has also hurt my important friends now, and I will not let him go. ”

"What are you asking?"

"I want to ask, who people has Zhong Zhiming been in contact with in normal times?"

"That's a lot, there are almost all of them in our class, as well as those from other classes, and even from other schools. Lin Baizhou replied.

"Don't count the other schools, the third target of the murderer is likely to be in our school at present, you think about it carefully, who has a good relationship with him, or who has a big conflict. Luo Chuan asked solemnly.

"The third target?, the murderer still wants to commit crimes?" Lin Baizhou was taken aback.

"Well, at the moment, it's very likely. ”

"Let me think about it. Lin Baizhou immediately became serious, this is a level related to human life, so he naturally didn't dare to be sloppy.

"I guess there can be three or four, and you're among them, after all, your contradictions, uh...... It seemed to him quite deep. Lin Baizhou thought for a while and said.

"Okay, can you post the names of these three people you know on my WeChat. ”

"Absolutely. After Lin Baizhou finished speaking, he took out his mobile phone to open WeChat, and after typing on the keyboard for a while, Luochuan's mobile phone received a prompt sound.

"Are you asking these questions related to the third goal?" Lin Baizhou asked curiously.

"Hmm...... Yes. Luo Chuan thought about it, he didn't belong to the police system, so naturally he didn't have a confidentiality treaty, so he didn't plan to hide it from Lin Baizhou.

"Strictly speaking, in a serial murder case, the murderer's target must have a lot in common, but at the current location, in addition to Zhong Zhiming and Ye Ye, in addition to the suitor and the pursued, the two of them have not been able to find a third person who is related at the same time. Luo Chuan explained.

"I see, that's why you asked me who has a good relationship or a feud with Zhiming?"

"Well, almost, I also asked someone to ask Ye Ye over there, and when the time comes, I will synthesize the names with each other, and I think the results will be available." ”

"I heard Zhiming say before, the one named Chang Yeye seems to like ......" Lin Baizhou glanced at Luo Chuan and said with some hesitation.

"Well, she has a crush on me, so I think I'm the one who is related to both of them at the same time, so now I'm trying to find out if there's a second possibility. Luo Chuan said.

"Then you must be safe, this is not a trivial matter. Lin Baizhou said kindly.

"Don't worry, I'm fine. ”

"Then do you want to tell Xiao Yusi about this?" Lin Baizhou asked.

"Don't, tell her, I don't want to explain it again, you have been thinking more about it lately, because the murderer's third target, now I just guess that it is related to Ye Ye and Zhong Zhiming, and it may be that my guess has made a mistake, anyway, you should look at her." Luo Chuan said.

"That's nature, don't worry, if something happens to Yusi, I'll see you. Lin Baizhou patted his chest and reassured.

"Well, that's not necessary, you should also pay attention to your own safety, the school has not been peaceful lately. ”

"I can see it, this policeman is walking everywhere, and Ann can tell that I am male and female. Lin Baizhou didn't know why, but he suddenly came up with such a sentence, which made Luo Chuan smile, and the atmosphere was a lot more relaxed.

"That's nothing, I'll go first, I'll trouble you at noon. Luo Chuan suddenly stopped and said.

"Don't bother, don't bother, you pay attention to safety, I'll go find Yusi." Lin Baizhou said with a smile.

"Okay, see you later. ”

"See you later. ”

......

"How's your investigation going?"

After separating from Lin Baizhou, Luo Chuan dialed Ding Yumian's phone.

"It's already over, what about you?" Ding Yumian's voice came from the phone.

"I'm done, where are you now?"

"Class. ”

"Wait for me, I'll go find you. ”

"Good. ”

After the two classes met, they immediately informed each other of the results of their investigation and visit, but the results were unsatisfactory.

"No, not a single one. Ding Yumian sighed and said.

"Actually, this is also what I expected, Ye Ye and Zhong Zhiming's circle is completely different, how can they find related characters, and even Ye Ye and Zhong Zhiming are not very familiar, it's just that Zhong Zhiming unilaterally pursues Ye Ye. Luo Chuan said.

"So what to do, if you say that, the murderer's target is really you. Ding Yumian said anxiously.

"It's all just speculation, and it's not necessarily the murderer's real thoughts, I'm fine, don't be too nervous. Luo Chuan said comfortingly.

"No, you promised me, go home now, okay. Ding Yumian instinctively shook his head and said.

"No, I can't leave yet. ”

"Why!" Ding Yumian stood up violently.

"Don't get excited, sit down first, and listen to me. ”

Ding Yumian saw that Luo Chuan looked confident, so he slowly sat down.

"Say it. Ding Yumian looked at Luo Chuan intently, as if he was afraid that he would never see it again.

"Now there are two puzzles, one is the mystery of the iron nail left by the murderer, and the other is the correlation between Ye Ye and Zhong Zhiming, at first glance, we haven't solved all of them yet, but in fact, the murderer has left us room to think. Luo Chuan said.

"What's the leeway?" Ding Yumian asked puzzled.

"You think, the correlation between Ye Ye and Zhong Zhiming is almost minimal, and I can barely get together with me, besides, I still have a grudge against Zhong Zhiming, this connection is actually quite far-fetched, if I am really the third target of the murderer, then do you think, Ye Ye and Zhong Zhiming's connection is already small enough, plus me, who can the three of us contact? I don't think there is one. Luo Chuan said with a smile.

"That's true, but what if you're his last target?" Ding Yumian asked rhetorically.

"Uh......" This really stopped Luo Chuan, he did think that he might really be the murderer's third target, but he didn't think that he might be the murderer's last target.

"Then think about it, who is it good to kill the three of us at the same time?" Luo Chuan had to change the subject.

"Nope. Ding Yumian instinctively shook his head.

"yes, so this proves that my initial speculation may be wrong, because no one has a grudge against the three of us at the same time, so the focus of the problem must be on the iron nail, so I can't go now, I have to solve the mystery of this iron nail. Luo Chuan's tone suddenly became a little heavier and said.

"But there are no police. ”

"If I know that the third target may be myself, I don't do anything but hide, it's useless, because the murderer can afford to wait, at least so far, I can't find any clues about the murderer, so I can't hide, I have to find him out before he can do it. Luo Chuan patted Ding Yumian's shoulder and said.

"Luo Chuan, you really can't have an accident, do you understand. Ding Yumian didn't know what to use to refute Luo Chuan, because what Luo Chuan said did make sense, but she really didn't want to see Luo Chuan have an accident, although Luo Chuan's ability was very strong, but I don't know why, her mood has been particularly unstable recently, and her mood is particularly anxious, which is actually really not a good sign.

"Don't worry, I won't have an accident, and thank you for helping me ask so much useful information at noon. ”

"What's the use, in the end there is still no clue at all. ”

"There's no clue, it's actually a clue. ”

......

"This case is the biggest impact and the worst case that has occurred in the city so far, the main target of the murderer is selected among the students of Pearl University, they are all a group of proud children, if they are attacked one by one, this is our responsibility, so now we must arrest the murderer as soon as possible, and return the society to a calm. Liu Zhenhui said excitedly in the conference room.

"Wang Ju, come up and say a few words. After Liu Zhenhui finished speaking, he glanced at Wang Yue, who was sitting on his left, and then walked down from the high platform and sat in his place.

"I am Wang Yue, the person in charge of this case, and I will briefly describe the clues we have found now. Wang Yue walked onto the high platform with a serious face, and then nodded to Zhang Sijia in the audience.

Soon, several photos appeared on the big screen, the first of which was the bath where Zhong Zhiming was killed.

"This is the first victim in this case, male, 19, Zhong Zhiming, a student of the seventh class of the first year of Pearl University, was found dead in the bathroom of Pearl University on March 25, and after forensic testing, it was found that he died of metal mercury poisoning. ”

"We found a large number of high concentrations of mercury vapor near the drain of the bath, and it is believed that the murderer used these mercury vapors to cause poisoning of the deceased, because the deceased had a relatively serious kidney disease before his death, and unfortunately caused severe acute kidney failure after the mercury poisoning, and finally died in a coma. ”

"We also noticed a strange phenomenon at the scene. Wang Yue raised her hand and pointed to the second photo.

"This is an iron nail nailed to the bath floor found at the scene, in which the photo of the deceased was painted with a big X, and then nailed to the ground, this phenomenon is likely to be the murderer's murder notice, so when this phenomenon was discovered, we initially suspected that the murderer was likely to continue to commit crimes. ”

"Wangju, what does the iron nail portend, and how did you deduce that the murderer would continue to commit crimes?" asked a police officer affiliated with another agency.

"If the meaning of the iron nail is only to fix the photo demonstration, there is no need to nail it to the ground, the bath is closed, there is no ventilation around it, just put the photo directly on the ground or next to the deceased, there is no need to go to great lengths to run after the murder to nail the nail to the ground with a hammer......"
