It stands to reason that a murderer will not bring too many things with him, after all, the more things, the easier it is to reveal his identity, so what makes the murderer work so hard to do these things?

Liang Fanxin couldn't figure it out, scratched his head, and looked at Lu Yifan.

At this time, Lu Yifan was standing next to the security door, looking intently at the place where the door lock was broken. Liang Fanxin originally wanted to ask questions, but when she saw Lu Yifan's focused appearance, she still couldn't help but follow and look.

"Wow, madman, how did you open the door and break the lock?" Liang Fanxin saw the location of the lock of the security door and asked the madman exaggeratedly.

"I kicked it off!" The madman scratched his head and said embarrassedly, "I was worried that the victim would still be rescued, so I kicked in the door in a hurry." ”

Between the security door locks, there are pieces of iron debris on the ground, and a broken pin, which looks like it has been violently destroyed.

"Okay, you're fierce!" Liang Fanxin said helplessly, but seeing Lu Yifan's full body concern, Liang Fanxin couldn't help but be curious.

"Boss, what's wrong, is there anything suspicious about these things?" Liang Fanxin leaned over curiously and asked Lu Yifan.

"This pin is so badly worn." Lu Yifan picked up the broken pin on the ground and said. Liang Fanxin leaned over to take a look and found that this was indeed the case. The door pin, which was supposed to be a cuboid, now looks like a trapezoid, and it looks like it has been worn out after long-term use.

"Is this the wear and tear caused by the owner's long-term use, or is the murderer using the secret room created here to kill people?" Liang Fanxin asked Lu Yifan curiously, if you have any doubts, Lu Yifan will not be able to read it so seriously.

"I can't confirm it yet, maybe it has something to do with the case!" Lu Yifan said, and the pin that came out of the sealing bag put away the broken pin.

"Keep an eye on the scene, and if there's anything suspicious, be sure to put it away!" Lu Yifan told the police at the scene again.

"Okay Lu Shen, we'll pay attention." The other policemen also hurriedly responded.

A group of people watched as the technical team carried the body back to the police station, so they all followed.

"Boss, do you think this case was done by the murderer?" Liang Fanxin walked into Lu Yifan's office, looked left and right, and saw that no one was paying attention here, so he asked Lu Yifan.

"Looking at it now, it's more likely that it's him." Lu Yifan nodded and said to Liang Fanxin, "But looking at it now, there are still some doubts, so I can't be sure yet." ”

"Don't forget, Lu Changfeng is still in detention. We are still holding him here, but the murderer is committing the crime outside again, does it prove that he is not actually the murderer, we all blame him! Liang Fanxin said to Lu Yifan, "Is it possible to release him, originally a button of evidence was not enough to detain him, but now that this kind of thing has happened, I feel that it is better to release him." ”

"It's a little early for him to be released now, or it's better to be sure, and the murderer in this case is the serial murderer, right?" Lu Yifan said with some hesitation.

"Lu Changfeng, who is still detained, I am afraid that Zhang Jinyong will suspect that Dao Tianxue's case is related to this case. Don't forget, in this case, that symbol can be seen by many people, even if they can't think of the random murder case for a short time, but Zhang Jinyong will definitely understand. Liang Fanxin said worriedly.

"Are you afraid that Zhang Jinyong will urge us to close the new case, and then affect Tian Xue's case?" Lu Yifan asked suspiciously.

"Absolutely!" Liang Fanxin said affirmatively, "The serial murder case is a pain point for Zhang Jinyong, and we will never be allowed to touch it easily!" ”

Liang Fanxin persuaded like this, Lu Yifan also hesitated a little, the new secret room murder case will definitely be known by Zhang Jinyong to be related to serial killings, so Tian Xue's case must not be allowed to interfere anymore.

"Okay, release Lu Changfeng. But be sure to monitor his whereabouts for a while to make sure there are no problems. Lu Yifan thought about it for a while and said to Liang Fanxin.

"I understand, I asked the monkey to arrange this matter, and sent someone to follow him for a while." Liang Fanxin said affirmatively.

So Liang Fanxin went to Lu Changfeng's interrogation room and bent down to unlock the handcuffs.

"Team Lu said, you are not suspicious for the time being, so you can go back." Liang Fanxin said, and suddenly felt a chill behind him.

Liang Fanxin suddenly felt that the hairs on his body were about to stand up. This feeling is familiar to her, and it feels every time she hits a ghost, and it is extremely clear and familiar.

Liang Fanxin raised his head and looked in the direction of the coolness, but only saw Lu Changfeng with a sunny smile.

"Thank you, Officer Liang, is it because there has been new progress in the case, why did I clear my suspicion?" Although Lu Changfeng was smiling, Liang Fanxin's face was shocked, and there was still a palpitation in his heart.

She looked left and right, but found nothing unusual. Could it be that because I went to the scene of the crime today, I bumped into something? Liang Fanxin guessed.

"It's okay, it's just that I didn't get any useful clues from you, so you don't have any suspicions, go back quickly." Liang Fanxin was anxious to escape from the interrogation room, so he said to Lu Changfeng that he would be the first to leave the interrogation room.

Lu Changfeng sat up and moved his wrist, and followed Liang Fanxin out of the interrogation room.

released Lu Changfeng, Liang Fanxin trotted to Lu Yifan's office in shock, and then walked to Lu Yifan's side without saying a word, and then carefully pulled his sleeve.

"What's wrong, what's wrong?" Lu Yifan saw Liang Fanxin's frightened look, so he hurriedly asked.

"I feel as if something is entangled in me......" Liang Fanxin looked left and right, and said in a bit of panic.

"How can this be, is it because you just went to the scene of the crime?" After Lu Yifan heard it, he also looked left and right, but he didn't see anything, so he asked Liang Fanxin guessingly.

"I don't know, so borrow your arm to use it first and see if it really works!" Liang Fanxin said, bringing Lu Yifan's arm closer, and the whole person was about to stick to him.

Since the last time he knew that Lu Yifan could help him exorcise ghosts, Liang Fanxin regarded Lu Yifan as a talisman, and came to him for help when he was a little troubled.

"Wow, this is in the office, you two don't have to be so anxious, right?" The door of the office was suddenly pushed open, and Guo Jing, who was in a hurry, came in just in time to see Liang Fanxin holding Lu Changfeng's arm, so he said with an exaggerated face.

"Bapo Guo Jing, it's not what you think!" Liang Fanxin hurriedly let go of Lu Yifan's arm, and then said to Guo Jing with a blushing face.

"Okay, don't make a fuss, what's the matter?" Lu Yifan looked at the shy Liang Fanxin and the smiling Guo Jing helplessly, and asked him.

"By the way, boss, it was the technical department that sent the preliminary inspection report over, thinking if we should have a meeting, touch the clues, and see the next direction of the case?" As soon as Lu Yifan reminded him, Guo Jing remembered what was going on, so he hurriedly said to Lu Yifan.

"Okay, let's go talk about it now!" Lu Yifan said, got up and went to the conference room with Guo Jing.

"Okay, everyone's here, let's talk about the clues we have now!" Seeing that everyone had arrived, Lu Yifan took the lead in speaking, and then looked at the madman.

Because the madman was the first to arrive at the scene, when he was at the scene, Lu Yifan handed over some investigation information and other work to the madman.

"The deceased, Liu Xuehan, died in his own home, and the door was locked, and there was no place to enter or exit. That is, the house where she died was a secret room. And the symbol under her is the symbol that serial murder will leave behind every time he commits a crime, but this time it is extraordinarily large. The madman said, pulling out some photos taken at the scene.

"In addition, according to some information about Liu Xuehan's family, she has cancer and often goes to the hospital for treatment, and this day should have been the day she went to the hospital for treatment, but she didn't expect to die at home!"

"Do you know her background?" Lu Yifan asked.

"No, she is from another province and came to work in M City. However, after the cancer was diagnosed, he did not return to his home, but he still lived in a rented house and went to treatment on time. So the information from her family will take some time to investigate. The madman returned.

"What's the message from the technical team?"

"First of all, let's talk about the cause of Liu Xuehan's death!" The madman took out a report, "Liu Xuehan's direct cause of death was that the vein in his wrist was severed and he died of excessive bleeding!" ”

"It's no wonder that you draw such a big symbol and die without bleeding too much." Liang Fanxin muttered after hearing this. When Lu Yifan heard this, he glared at her fiercely and signaled her not to interject casually.

"The important thing is that the gauze wrapped around Liu Xuehan's hand is not a part cut off by the murderer, but the original old wound!" The madman looked at Liang Fanxin and said slowly.

"What?! Impossible, how could there not be any missing parts? Liang Fanxin shouted in disbelief.

"What about the other organs, have you done a full body examination?" Lu Yifan asked in disbelief.

"I'm sure it's been checked, and no organs are missing!" The madman said affirmatively, and then handed the report in his hand back to Lu Yifan and asked him to see it for himself.

Lu Yifan flipped through the report in his hand and found that it did not say that any organs had been removed. It only focused on the direct cause of death, and the remaining wounds from before.

"What's going on, isn't the murderer the murderer of a serial murder?" Liang Fanxin saw that Lu Yifan didn't speak, so he knew that the report was the same as what the madman said, so he asked in surprise.

"Not necessarily, the matter of that symbol is still difficult to explain, maybe there are some things in the deceased that we have overlooked." Lu Yifan said with some uncertainty.

"Boss, in fact, I feel that the deceased is suspected of suicide." The madman thought about it for a moment and said to Lu Yifan.

"Tell me what you think." Lu Yifan thought for a while and said to the madman. Because from seeing the symbol under the deceased, Liang Fanxin and Lu Yifan basically believed that the deceased's death was related to the serial murder case, but they never thought that the murderer would commit suicide.
