According to the evidence and reasoning obtained so far, Luo Chuan believes that the mysterious man is not the person who came from the same path as Chang Zhenghao, and the reason why he is following Chang Zhenghao is that he has a huge hatred for him and is looking for an opportunity to kill him.

Although there are still many doubts that have not yet been solved, such as why Chang Zhenghao frequently haunts the police's field of vision, is he provoking the police or hinting at the police? Could it be that Chang Zhenghao already knew that someone was going to kill him, so he deliberately lured the police over? At present, this inference is still somewhat credible.

After Chang Zhenghao's case was sorted out clearly, there were only the splendid jewelry robbery case and the Xu Mingliang case in front of Luo Chuan, Luo Chuan sorted out the information of Chang Zhenghao's case, and marked some important connections on the whiteboard, and then took out the poor Xu Mingming's case information that was only one page and had little information.

Xu Mingliang died of suffocation, the body was dumped on the sign of the central hospital, suffocation is very simple, divided into drowning and strangulation two causes of death, through the examination of the body that day, it is concluded that Xu Mingliang died of a murder weapon like a rope, and finally suffocated to death.

Now there are several questions, why did the murderer throw Xu Mingming's body on the sign of the central hospital, did he really want to demonstrate to the police, if so, he could have thrown it on the street, why did he have to arrange such a sense of ceremony, and Xu Mingliang himself is also a criminal suspect on the run, what is the point of killing him to demonstrate to the police?

"Listen to the rain, did you say that the murderer threw Su Mingming's body on the sign of the central hospital really just to demonstrate to the police?" Luo Chuan frowned and looked back at Shen Tingyu's direction.

"Well...... I don't think it's a demonstration against the police, it's a bit like a demonstration against the criminal gang. Shen Tingyu couldn't help but check the case information before Luo Chuan arrived, and naturally had a certain understanding of the Xu Mingliang case that happened yesterday and the splendid jewelry robbery that happened not long ago.

"Good idea!" Luo Chuan's eyes lit up, and Shen Tingyu's idea was not impossible.

As a family member of a victim, I hope these criminal gangs will be punished as they deserve, but the police have not succeeded in arresting them, and he can only take revenge in his own way.

On the one hand, it is a demonstration of the criminal gang, so that they have the psychology that everyone is in danger, and then hang the body in the central hospital, this act is very likely to just convey, you see, you police can't find the person, I helped you find it, and now I give it to you, it is very likely that the murderer has reached a kind of pathological psychology.

"I'm going out for another trip, so you can rest here for a while. Luo Chuan suddenly stood up from the workbench, and after sorting out the materials, he said hello to Shen Tingyu, who was resting on the sofa.

"I want to go with you. When Shen Tingyu heard this, he immediately sat up.

"Obedient, you're tired after a morning of tossing, so stay here and rest. Luo Chuan said comfortingly.

"I'm fine, I can go. Shen Tingyu shook his head stubbornly.

"That's it, you can help me sort out and summarize the information here, there are some doubts that I haven't figured out yet, I want you to help me, okay?" Luo Chuan thought about it and said in a different way.

"Okay, what do you want me to help with?" Shen Tingyu's eyes lit up instantly, and he immediately cheered up and looked at Luo Chuan.

"You see, now Chang Zhenghao's case, the key is the mysterious person, after inference, we conclude that the mysterious man and Chang Zhenghao are not the same way, and have a deep hatred with Chang Zhenghao, Xu Mingliang was killed yesterday, whether the murderer is this mysterious person is still difficult to say, I hope you can try to find some common points in these two things, if you can prove that the murderer of Chang Zhenghao and Xu Mingliang is a person, the resistance of the case will really be much smaller. Luo Chuan said with a serious face.

"Okay, I see. Shen Tingyu nodded.

"Okay, I'll go first, and I'll wait for me to come back. Luo Chuan smiled, then picked up his coat and left the hut, leaving Shen Tingyu alone to think about it.

Ten minutes later, Luo Chuan appeared at the entrance of the lobby of the central hospital, and after a little observation around, he walked into the hall.

"Hello, I want to find a cleaning employee named Bei Qionglan, this is my ID. Luo Chuan walked to the front desk of the hospital, nodded politely to the staff working at the front desk, and then showed the investigation team certificate that Wang Yue handled for him, and temporarily added a photo to Luo Chuan, so Luo Chuan's current behavior can completely represent the police.

"Ah...... I'll find the contact information for you, please wait. ”

The young lady at the front desk was obviously a little surprised, after all, Luo Chuan's age seemed to be in his early twenties, and he was probably a school student, but he didn't expect to serve as the leader of a task force, which shows that this teenager's ability is absolutely extraordinary.

After contacting, the front desk staff asked Luo Chuan to wait for a while, saying that Bei Qionglan would come over soon.

Sure enough, five minutes later, Bei Qionglan ran to the front desk in a hurry, and then looked around, revealing a look of doubt, and finally locked on Luo Chuan.

"Officer, are you looking for me?" Bei Qionglan looked at Luo Chuan tentatively, obviously she didn't think that the policeman who was looking for her was the handsome and delicate teenager in front of her.

"Well, let's find a quiet place to talk. Luo Chuan smiled and directly showed his police officer card, and Bei Qionglan was relieved.

"Come with me, the lounge shouldn't be empty by now. With that, Beqionglan led the way ahead.

The lounge is for them cleaning staff, usually when the flow of people is low, they can come to the lounge to rest for a while, drink water or something, but today the hospital is a bit crowded, so the lounge is temporarily empty.

"I want to ask what you were doing last night. ”

Closing the door of the lounge, Luo Chuan motioned for Bei Qionglan to sit down, and Bei Qionglan shook her head, obviously a little nervous.

"Last night, I was in charge of cleaning the fifth floor with Chunzhu, and then the leader called me and said that the cleaner in charge of the top floor sanitation had asked for leave today, and asked me if I could clean it for her, and I thought it was nothing so I agreed. ”

"Later, after Chunzhu and I finished cleaning the area we were responsible for, I told Chunzhu about it, and she said that she was fine, so she asked me to go home first and she cleaned it for me directly, and I was really anxious to go home to see the children at that time, so I agreed, and then I changed into my work clothes and went home. Beqionglan explained.

"Do you know what happened on the top floor of the hospital last night?" Luo Chuan asked.

"I know, it was Chunzhu who told me this morning, I didn't believe it at first, I thought she was a prank, but then I saw so many police coming to the hospital in the morning, and the top floor was blocked so I believed her words, it's really terrible. ”

"What is your relationship with this girl named Chunzhu?" Luo Chuan continued.

"It's a colleague who works together, she is four or five years younger than me, and her personality is quite lively, and she is divided into a work area, usually talking and chatting, and the relationship is also very good. ”

"What time did you leave the hospital last night?"

"It's almost seven o'clock. Bei Qionglan thought for a moment and said.

"Are you sure you haven't been to the top floor since yesterday?" Luo Chuan's eyes locked on Bei Qionglan as sharp as an eagle, as if he could see through everything in her heart.

"No, I've been with Chunzhu before I get off work, and I've never been to the top floor. Beads of sweat had already appeared on Bei Qionglan's forehead, and for some reason, when facing Luo Chuan, she felt an unprecedented pressure, which made her a little breathless.

"Okay, thank you for cooperating with our investigation, and can you help me get the girl named Chunzhu over, I have something to ask. Luo Chuan put away his sharp gaze, and instead showed a kind and sunny smile, and that powerful aura disappeared without a trace in an instant.

"Okay, okay. Bei Qionglan nodded, and then fled out of the room.

Although she didn't do anything wrong, she didn't know why, she felt particularly nervous and uneasy in front of Luo Chuan, so she immediately escaped from the room after the questioning.

In about ten minutes, Luo Chuan waited for Qiao Chunzhu, compared to Bei Qionglan's restraint and nervousness, Qiao Chunzhu was obviously much more generous and comfortable.

"Wow, officer, you're so handsome. Qiao Chunzhu sat beside Luo Chuan like a nymphomaniac with his eyes.

"Thanks for the compliment, I need to ask you something about what happened last night, please cooperate. Luo Chuan showed a polite smile.

"Okay, you ask, I must know everything, I must know everything. Qiao Chunzhu looked at Luo Chuan with a grin.

At first, she was actually a little nervous, after all, she was questioned by the police, and after Bei Qionglan was questioned, her whole face showed that restrained and uneasy expression.

But the moment he saw Luo Chuan, this tension seemed to dissipate in an instant, and was replaced by a expression common to a young girl.

"You found the body last night, right?" Luo Chuan put away his playfulness and began to ask.

"Yes, I was cleaning on the top floor, and then I suddenly felt that the light of the light sign was a little darker, so I went over to take a look, and found the body, and hurriedly called the police. Qiao Chunzhu replied.

"You didn't touch the corpse at that time, did you?" Luo Chuan asked.

"No, there is surveillance on the top floor, little brother...... If the police officer doesn't believe it, he can go to investigate the surveillance, and if nothing else, he should be able to photograph me, and I am more active when I am working. Qiao Chunzhu said with a smile.

"You don't look scared, do you?"

"Hehe, isn't this a police officer, you're too handsome, and you were scattered before you had time to be afraid. ”

“......”

"Okay, was the place where you saw the body last night on the sign with the word "doctor"?"

"Yes......"
