Maybe the madman is the bystander, and he may see more.

"First of all, the death of the deceased is in a confined space. We can interpret it as a murder in a closed room, but it can also be interpreted as suicide by hiding in a house because you don't want to be brought down. The madman said to the other four.

"You know, the deceased was a terminal cancer patient. Why did he not return to his home after the cancer was confirmed, but continued to live in a dilapidated house that he rented? This is highly suspicious. ”

"And the murder weapon that killed the deceased was also found at the scene of the crime, and it was pressed under the deceased, an ordinary fruit knife, on which there were no fingerprints of any one except the fingerprints of the deceased."

"And the symbol you said may have an explanation, boss." Guo Jing added helplessly.

"This is a robot vacuum cleaner found under the bed of the deceased without electricity. It was still soaked in blood when we found it. Guo Jing said, and took out a photo, which showed a round sweeping robot soaked in blood.

"What do you mean?" Liang Fanxin asked inexplicably.

"Maybe those relatively wide handwriting were not left by the murderer, but after the deceased committed suicide, the sweeping robot started its work by itself, and then passed by the deceased and touched the blood, so that the symbol would be drawn." Guo Jing said guessingly.

"This can't be, how can it be so coincidental!" Liang Fanxin said in disbelief.

"Of course,This is just a guess on my part.,Whether it's a symbol drawn by a sweeping robot.,It should have to be proved again.。 And why did the deceased not go home when he was diagnosed with cancer, but lived in a rented house and quietly recuperated? Guo Jing stretched out his hand and said helplessly.

"Maybe you're right. I'm now entangled in serial murders, and any case is entangled with serial murders. Maybe this case is just a simple suicide case. Lu Yifan rubbed his faintly aching head and said to the others.

"Boss, I don't think it's that simple!" Liang Fanxin stood up and said anxiously, "I don't believe that so many coincidences will happen. I don't think it is possible to deny that the murderer of a serial murder did the crime just because the killer did not take anything from the deceased. ”

"Now we're not saying that just because of these clues now, we will disprove the previous speculation. Rather, these two speculations now have their own reasons and have a certain degree of plausibility. So we need to continue to investigate and finally determine how the deceased died! Lu Yifan helplessly explained to Liang Fanxin.

"Just ask her how she died." Liang Fanxin had a flash of inspiration, and suddenly said to Lu Yifan.

"Hey, Liang Da Beauty, I'm cowardly, you're scaring me! What do you call to ask the deceased, are you going to go to the morgue and ask her body? The monkey asked tremblingly.

"Cut, monkey, you're too cowardly, it seems that you can't call you a monkey, you have to call a mouse!" Liang Fanxin sneered at the monkey.

When Lu Yifan heard Liang Fanxin's words, he glanced at her with some surprise. Liang Fanxin is particularly resistant to his own ability, why did he suddenly think of using his ability to solve the case?

"Anyway, I've been targeted, and I can't hide, so it's better to go with the flow." Liang Fanxin shrugged his shoulders and said helplessly. Lu Yifan remembered her panicked appearance just now, and it seemed that there was really no way but to use her ability.

"Boss, how are we going to investigate next?" Guo Jing looked at the two of them and didn't understand what they were talking about, so he asked Lu Yifan.

"Two ideas in parallel at the same time! Guo Jing, you go to the investigation technology team and ask them to investigate the sweeping robot to see if anyone has tampered with it. I don't think it's such a coincidence that I drew that symbol myself! Lu Yifan explained to Guo Jing.

"Crazy, you investigate Liu Xuehan's other information, go through all the documents moved from her house, and see if there is any missing information!" Lu Yifan explained to the madman, "If it is suicide, in addition to illness, there should be other reasons." ”

"Okay boss, got it!" The madman and Guo Jing nodded and said.

"Yifan, are you in a meeting?" As soon as he finished explaining, Zhang Jinyong slowly walked into the conference room with his hands behind his back.

"Director!" Lu Yifan stood up and said hello, then motioned for the meeting to be dismissed and let everyone else out.

"I learned about the case that just happened, and it seems that the symbols that appeared in the serial murder case were left at the scene, what's going on?" Zhang Jinyong asked Lu Yifan expressionlessly, "Are you sure he did it?" ”

"Director, there are still many doubts in this case, and it is still uncertain that it is related to the original serial murder case!" Lu Yifan said to Zhang Jinyong, "Now there are two possibilities in the case, one is suicide, and the other is homicide!" And the clues of this case and the serial murder case are not quite the same, not quite like the style of the murderer. ”

Lu Yifan understood why Zhang Jinyong cared so much about this case. If the public knows that the serial murderer has come out to commit crimes again, then the cases that Zhang Jinyong closed at the beginning will be wrong, which will inevitably affect his career and prestige. So he definitely won't let this case be linked to the original serial murder case.

"And what's going on with that symbol at the scene?" Zhang Jinyong asked with a frown. Although he was relieved to hear Lu Yifan's explanation, Zhang Jinyong was a little worried when he thought of the symbol that was seen by many people.

"Even if there is that symbol, it doesn't mean anything, it's probably a copycat! After all, there were many suspected imitation cases four years ago! Lu Yifan said lightly, but he didn't mention the matter of the sweeping robot.

"I see!" Hearing Lu Yifan say this, Zhang Jinyong was completely relieved.

"The first group still has Tian Xue's case in their hands now, should they hand over this case to the second group first. They don't have any important cases right now and can have more energy to deal with this case. Zhang Jinyong thought about it for a while and proposed to Lu Yifan.

"Director, no need! We can be busy here, and we don't need the second group to interfere! Lu Yifan hurriedly said, "And this case is not too complicated, so it is very likely that it will be closed soon!" ”

"Well, in that case, you should do a good job and close this case as soon as possible! I'm afraid that this case will spread and make the public think that it was done by a serial murderer, and then cause panic! Zhang Jin never left a trace to explain to Lu Yifan.

"Okay Director, I understand!" Lu Yifan nodded, indicating that he knew what he meant.

Zhang Jinyong's goal was achieved, so he left a group of offices. When Liang Fanxin saw it, he hurriedly walked over.

"Boss, what is this old fox doing?" Liang Fanxin saw Zhang Jinyong's back and asked Lu Yifan with a grin.

"What else can I do, I'm not afraid that this case is related to a serial murder case, urge us to close the case quickly!" Lu Yifan said helplessly.

"In order to make up for one lie, more lies must be made up!" Liang Fanxin said lightly, Zhang Jinyong is in this situation now, in order to cover up the serial murder case that he used to imitate the murderer to close the serial murder case, resulting in every case that may be done by the serial murderer, the case must be closed in other ways. If this situation is understood, it will definitely lead to more and more wrongful cases, and the longer it lasts, the more difficult it will be for Zhang Jinyong to get out.

"Okay, I've sent him away, don't bother with it." Lu Yifan rubbed Liang Fanxin's head, "Don't gossip here, this case doesn't need so many people, you better think about what Tian Xue should do!" Now she is biting and saying that the person was killed by herself, and if there is no clue all the time, she can really only close the case as she said! ”

"I really don't have any clues in this case, Gao Cheng didn't see the murderer at all, so he couldn't give me any hints!" Liang Fanxin said helplessly.

"By the way, isn't this case related to a serial murderer now, we can investigate this case, then find clues to the murderer, and then return to Tian Xue to investigate, in this case, maybe both cases have ideas!" Liang Fanxin said in surprise.

"But what if this case has nothing to do with serial murder?" Lu Yifan suddenly asked Liang Fanxin.

"Then, if it doesn't matter, then I can only investigate your brother again!" Liang Fanxin stuck out his tongue and said helplessly.

"Okay, don't worry about Tian Xue's side for now, let's concentrate on investigating the case here!" Lu Yifan said helplessly, "You go and assist the madman to investigate the documents in Liu Xuehan's home and see if there is anything valuable!" Lu Yifan saw that Liang Fanxin didn't want to face Tian Xue anymore, so he could only arrange for her to do other work.

"Okay boss!" Liang Fanxin happily saluted Lu Yifan, and then happily walked to the madman's desk.

"Madman, have you found anything!" When Liang Fanxin walked over, the madman was burying his head in looking at various documents, "The boss arranged for me to come over to help you." ”

"Look, here are some documents from the deceased's house, a lot of things! What water bills, electricity bills, rent lists, as well as some inspection reports, physical examination lists, insurance policies, all of them, you take a look one by one, there are any suspicious points! The madman explained to Liang Fanxin.

"Insurance?" Liang Fanxin heard these two words keenly, and then pulled out an insurance policy.

"This is the accident insurance I just bought recently! The beneficiary is her Liu Feng? Who is Liu Feng? Liang Fanxin looked at the insurance policy and asked the madman.

"Liu Feng is Liu Xuehan's younger brother! What's wrong, is there anything strange about this insurance? The madman asked curiously.

"Are you stupid, Liu Xuehan is already terminally ill of cancer, and there is no insurance company that will accept her insurance, how can this insurance be passed, imagine that you are tired!" Liang Fanxin hated that iron could not become steel.

"I remembered when you said this, I just saw an examination report, which showed that Liu Xuehan was in good health and did not have any diseases! I looked strange just now, but now that I think about it, could it be that she deliberately forged a medical examination form in order to buy insurance? The madman said, pulling out one of the dozen lists classified by the physical examination list and handing it to Liang Fanxin.
