"It must be so, this physical examination form must be forged, just to take out this accident insurance! Well, it is very likely that her death was also in her plan. Liang Fanxin guessed, "I knew that I wouldn't live long, so I forged a physical examination form, took out a huge amount of insurance, and then faked murder, just to defraud the insurance money!" ”

"It's very possible to guess like this, this is the motive for her suicide!" The madman nodded and said, I originally felt that Liu Xuehan's motive for committing suicide because of illness was not reasonable at all, but now that he finds this forged physical examination certificate and insurance policy, then everything can be explained.

It's all about fake murder and deception!

"Call the insurance company and see if it's true!" Liang Fanxin took out the insurance policy, and then according to the address, he and the madman came to the office building of the insurance company.

"Hello, police case, find your manager!" Liang Fanxin directly hung out the documents and said to the front desk person. Then, led by the front desk, I went to the manager's office.

"We want to ask, did Liu Xuehan take out a huge amount of insurance here!" Liang Fanxin hung out the insurance policy and asked the manager bluntly, "Now that Liu Xuehan is dead, we suspect that it has something to do with this insurance!" ”

"Liu Xuehan, I have an impression of this person! She paid 100,000 yuan for accident insurance! She's dead? What's going on, is it suicide? The manager asked in surprise, and asked professionally. After all, if you just buy insurance and die, anyone will doubt it.

"It's not certain yet. Just to make sure, if the police convict him of homicide, how much will you pay? Liang Fanxin asked.

"At least a million!" The manager said dejectedly.

"Okay, got it!" Liang Fanxin nodded, and left the manager's office with the madman!

"It's really a good means, using my own life that was about to end, and directly turned 100,000 into 1 million, I want to buy one for myself!" Liang Fanxin said ridiculously and angrily.

"Forget it, if the insurance company knows that Liu Xuehan has cancer, I'm afraid that this insurance will be invalidated directly, and I won't admire it at all!" The madman shook his head and said.

"Okay, at least we are sure that Liu Xuehan is indeed suspected of preparing to cheat the insurance!" Liang Fanxin said affirmatively, "Go back and talk to the boss." ”

The two then drove back to the police station, and when they returned to the office, they saw Guo Jing holding the sweeping robot and talking to Lu Yifan.

"You came back just in time, Guo Jing has found something here, let's talk about it!" Lu Yifan greeted Liang Fanxin and the madman.

"Coincidentally, we've found something here!" Liang Fanxin said with a smile, and then followed Lu Yifan into the conference room.

"Guo Jing will say it first!" Lu Yifan said to Guo Jing.

"Okay, it's about this robot vacuum! I have researched the information of this robot vacuum cleaner from the Internet! It allows him to sweep a fixed position based on the layout of the room you enter. In other words, its walking trajectory can be planned! Guo Jing said, connecting the robot to the computer and opening its built-in program.

"It's based on the layout you enter, and it automatically produces the walking program! But inside this robot, a fixed program has been entered! ”

"I talked about my experiments in the technical group, and found that the process of its walking is the symbol left by the serial murderer, that is to say, the huge symbol left at the scene is actually left by the sweeping robot!" Guo Jing finally came to a conclusion. At the same time, a video was also shown, which seemed to be the process of Guo Jing experimenting with sweeping robots, and the symbols drawn in the end were exactly the same as those at the scene of the crime!

"In other words, this symbol was not drawn by the murderer, but left by the robot after the deceased died!" Liang Fanxin said, "Then it is very likely that after the deceased committed suicide, the robot program set up to draw this symbol!" ”

"It's too early to say suicide, and it may be a program designed by the murderer, so it's suspicious!" Lu Yifan retorted.

"Boss, after reading what we found here, let's talk about whether the deceased committed suicide!" In the face of Lu Yifan's rebuttal, Liang Fanxin was not angry, but took out two documents in his hand.

It was Liu Xuehan's forged physical examination form and accident insurance!

"This is Liu Xuehan's forged physical examination form and the accident insurance he just took out recently. The insurance company said that if Liu Xuehan died in an accident, it would pay 1 million to the beneficiary, that is, Liu Xuehan's younger brother! Liang Fanxin said confidently, "This is why I said that Liu Xuehan committed suicide, and I had to work hard to fake the scene of his killing, in order to defraud a huge amount of insurance!" ”

Lu Yifan stretched out his hand and took the two documents in Liang Fanxin's hand and looked at them seriously.

"Yes, you two, you'll get the clue so quickly." Guo Jing said to Liang Fanxin with a playful face.

"That's a must, don't look at it and it's me Detective Liang who came out in person, so naturally he was able to catch it!" Liang Fanxin said proudly.

"That's not right!" Lu Yifan finished reading the documents in his hand and said with a solemn face.

"What's wrong, what's wrong?" Liang Fanxin hurried over and asked nervously. At the same time, he stretched out his hand to take the slip in Lu Yifan's hand, and reviewed it himself, "I don't think there's anything wrong with it?" ”

"Take a closer look at that medical checklist!" Lu Yifan said to Liang Fanxin.

Liang Fanxin looked at it carefully twice, and found that there was no difference at all from Liu Xuehan's correct physical examination list that he had seen before, and he didn't know what was wrong at all.

"I don't look like the real thing, what's wrong?" Liang Fanxin asked Lu Yifan strangely, and at the same time handed the physical examination form to Guo Jing and motioned for him to take a look.

"It doesn't seem like there's any flaw. Boss, what's the problem, don't sell it, tell us! Guo Jing watched it twice, and said to Lu Yifan with a wail.

"There is nothing wrong with this physical examination form, because this is a formal medical examination order issued by the hospital at all!" Lu Yifan said affirmatively.

"What's wrong, since you want to deceive the insurance company, of course, you must open the correct physical examination form, if you make a fake, it will be easier for people to see through it!" Liang Fanxin said as a matter of course.

"Yes, that's the suspicion. How did Liu Xuehan get this physical examination form? What is the relationship between the doctor who prescribed her a disease-free physical examination list and her, does this doctor know what Liu Xuehan is using this physical examination list for? Lu Yifan asked questions one after another, causing the others to ponder for a while.

"However, does this have anything to do with whether Liu Xuehan committed suicide?" Liang Fanxin thought for a moment and asked Lu Yifan.

"It matters! Liu Xuehan really wanted to use her death to cheat the insurance, but whether she committed suicide or killed him is not certain! Lu Yifan said firmly.

"At the first glance at the scene of the crime, I really felt that he was killed, which was also in Liu Xuehan's interests. But a closer look reveals the suspicions. And the murderer did not have other people's fingerprints, but took a fruit knife directly from the kitchen at random, so this case is very strange, because from the perspective of Liu Xuehan's interests, he should not do such unnecessary things! ”

As soon as Lu Yifan said this, others also understood. Indeed, there is too much evidence at the scene that can support Liu Xuehan's suicide, which is very unfavorable to Liu Xuehan.

"But if it was really him who killed, this matter can be explained like this!" Lu Yifan coughed lightly twice.

"It is very likely that the deceased and the murderer planned to commit the crime, and the deceased asked that he kill the scene, but the murderer did not want to leave too much evidence at the scene, so this scene was formed that looks like suicide and killing!"

"Boss, if that's the case, this case has nothing to do with a serial murder case at all." Liang Fanxin thought for a moment and said to Lu Yifan.

"No, they know it's suspicious! It doesn't have to do with serial killings, at least they should know that there are serial murders! Lu Yifan thought for a while and said.

"So what now? Investigate the doctor who helped with the fraud? Liang Fanxin took the physical examination sheet and asked Lu Yifan, "Since it is a fake, then this name should not be true, right?" ”

"No, it has to be true! Otherwise, the insurance company would not have passed so easily! Lu Yifan said affirmatively!

"Okay, then let's go to this hospital and investigate!" Liang Fanxin said resolutely.

"I suspect there is something really wrong with this doctor, let's go with us!" Lu Yifan thought about it for a while and said to Liang Fanxin.

So a group of five people rushed to the name of the hospital recorded on the physical examination list!

The location recorded on the hospital is a well-known hospital in City M, which is why the insurance company will recognize the medical examination report of this hospital.

"Hello, police case! Find Dr. Chen Lizhi! Liang Fanxin walked to the front desk of the hospital, took out his ID and said to the people at the front desk.

"Dr. Chen is in the office on the second floor, I'll take you there!" Seeing that it was the police, the nurse at the front desk hurriedly walked out and said to them, and then led them to the second floor.

"Dr. Chen, the police are looking for you!" The nurse led a few people to a room on the second floor that looked better-decorated, knocked on the door and said inside, and then pushed the door in.

After entering, there was a doctor in a white coat, with a thin figure, but he looked very energetic, and he looked less than thirty years old, which could be regarded as young and promising.

"This is Dr. Chan!" The nurse said to Liang Fanxin, and then retreated herself.

"Dr. Chen, take a look at this medical check-up form, this is your signature!" Liang Fanxin threw the physical examination sheet in front of Chen Lizhi and asked him.

A trace of panic flashed on Chen Lizhi's face, but he still tried to pretend to be calm, picked up the physical examination form, and looked at it seriously.

"Yes, that's my signature. But I don't remember the examination of this patient! Chen Lizhi said lightly.

"Well, it's enough to admit that it's your signature! Come with us, there is a case that needs your help in the investigation! Liang Fanxin said coldly, since he admitted it, it would be easy to do!

"Wait, can't you do it here? I also made an appointment for a lot of patients to have a check-up today! Hearing that the police were going to take him away, Chen Lizhi hurriedly said.
