"So do you know who the killer is?"

Jiang Yunfei looked a little excited. Zhao Fan glanced at him on the side, and followed Wang Qiang and Chen Zheng to the scene of the crime. The heart said: I am a student, and I am not a fortune teller~

"You ......" Jiang Yunfei pointed at Zhao Fan and wanted to say something, but he didn't say anything. He sighed with his hands on his hips and hurriedly chased after him.

From the time Zhao Fan came to the eighth floor, he began to look at everything around him. On the eighth floor, there is a shop selling all kinds of women's clothing. The number of people coming and going has not diminished because of the murders. When he walked to the door of the women's bathroom, Zhao Fan looked around and looked at the location of the surveillance. He didn't say anything, and walked straight in.

On either side of the entrance are washstands, and there are four cubicles on the left and right of the entrance. The murder took place in the last compartment on the left. Zhao Fan measured the distance between the washbasins and the distance between the left and right compartments. After looking at each compartment, we finally came to the last compartment in the rear left. Zhao Fan opened the door, and the first thing that caught his eye was bloody footprints and blood fingerprints. He then looked at the location where the deceased was found, and it was clear that the deceased was sitting on the toilet at the time of his death. Then the murderer did not seem to have abused the deceased. The murderer stood in front of the deceased and felt the passage of the deceased's life.

Zhao Fan worked hard to restore the situation at the scene in his mind, he wanted to see the murderer's facial expressions clearly, but the clues he got were not enough, no matter how hard he tried, he couldn't be sure.

Zhao Fan gave up this idea, turned around and looked at the height of the compartment door, when he saw the strange symbol, he felt a little familiar, but he didn't remember it for a while.

Zhao Fan opened the information brought by Chen Zheng. Carefully look for clues on it.

The deceased, Li Min, female, 26 years old, was a local. Working as a salesman in a clothing store on the 9th floor of Longjiang Shopping Mall. On the day of the incident, surveillance showed that the deceased entered the bathroom at around 8:50 minutes and has not come out since. The owner of the clothing store and the family of the deceased called several times, but they all prompted to turn off the phone. Zhao Fan looked at the photo of the deceased and looked at the knife edge of the deceased. The murderer's figure gradually became clearer.

"Gender, male. Between the ages of 35 and 40, he is thin and about 175 tall, and his dominant hand is right-handed. The exterior is relatively clean and tidy. Usually the popularity is not good, and it is extremely selfish. Impulsive and irritable. Have a severe psychological disorder. The job will not be very stable, and it should always linger at the bottom of society. ”

Jiang Yunfei saw that Zhao Fan had stopped, so he reacted, slapped Chen Zheng, and signaled him to write it down quickly.

"Gone?" Jiang Yunfei looked at Zhao Fan. Zhao Fan gave him a blank look and continued.

"The murderer knows a lot about this building, at least this floor, although there are four cameras outside that can shine here, but I don't think it is very likely that they can be monitored."

"Why?" Jiang Yunfei was very skeptical.

"It seems stupid for the killer to leave bloody footprints and blood fingerprints, but this is only a part of his planned crime. It doesn't mean that he is really so nervous. Daring to do so just shows that he is very confident in his modus operandi. With such self-confidence, it is impossible for him not to notice the existence of monitoring," Zhao Fan said in a low voice.

"Have you seen the video?" Zhao Fan suddenly turned his head and glanced at Jiang Yunfei.

"I've seen it, and there's no problem." Jiang Yunfei said affirmatively.

"What time zone are you looking at?"

"At eight o'clock on the day of the crime, the mall began to open until the officers on duty found out."

"The killer may have been hiding in the bathroom much earlier." Zhao Fan also frowned. Suddenly, Zhao Fan saw that there were traces of tobacco on the windowsill outside the window, and there was still a little cigarette ash left on it. Zhao Fan dipped his fingers in cigarette ash, and then rubbed them back and forth.

"Are you smoking here?" Zhao Fan asked Jiang Yunfei casually.

"What are you kidding, how can anyone smoke at the scene of the crime."

Zhao Fan nodded thoughtfully, and couldn't help but wonder in his heart: Why didn't the murderer just throw the cigarette in the toilet and flush it away, but chose to extinguish it on the windowsill? Could it be something other people do when they smoke? But no one else needs to do that.

Although he didn't know why he was snuffed out in front of the windowsill, Zhao Fan had a terrible idea.

"Could it be that the murderer has been here, quietly waiting for the victim to die?"

"Let's go, let's go to the monitoring room." Zhao Fan put his inner thoughts aside for the time being.

On the way, Jiang Yunfei thought of that weird symbol.

"Zhao Fan, what do you think of that symbol?"

"It feels familiar, I didn't think about it." Zhao Fan smiled bitterly.

"I also felt déjà vu, as if it had something to do with a serial murder." Jiang Yunfei is a self-respecting analyst. didn't notice that Zhao Fan next to him suddenly stopped his footsteps. When he turned around, he found that Zhao Fan was still behind.

Zhao Fan closed his eyes and continued to paint a portrait of the suspect in his mind. Jiang Yunfei's words just now reminded him, a serial killer! Isn't that symbol the special symbol of the "Zodiac Killer"? was right with Zhao Fan's prediction, the suspect in his mind stood in front of the victim, his expression was tangled, and he seemed to be struggling like the suspect.

A group of three people came to the monitoring room, and Chen Zheng showed the investigation certificate and explained his intentions. The staff found us four sets of surveillance footage from the day. Zhao Fan still asked them to start playing from eight o'clock, staring at the screen in front of them while chatting with the staff.

"you, you're hard, aren't you?"

"It's okay, it's just that the night shift is a bit timid, and the income is not much. It's just to pass the time. ”

Zhao Fan turned his head to look at the staff member, seeing that he was about to be in his twenties, he couldn't help but sigh a little in his heart. I didn't say anything, after all, there is too much helplessness in this society.

"yes, the night shift is harder, so what time do you usually work the night shift?"

"At seven o'clock, we change shifts at seven o'clock. The day shift comes at seven o'clock, and it's almost eight o'clock when you pack up. The mall opens at eight o'clock. ”

Zhao Fan was shocked in his heart, but he didn't show it.

"Dude, this speed is too fast, I'm a little dizzy, adjust it to normal, I'll watch it slowly." Zhao Fan moved a seat by himself and leaned back.

Hearing Zhao Fan's words, Jiang Yunfei was anxious on the side.

"Zhao Fan, what about you playing, you have to see the Year of the Monkey and the month of the Monkey at a normal speed?"

"Do you handle the case or do I handle the case? I didn't ask to come here. Zhao Fan deliberately said something that Jiang Yunfei didn't like to hear.

Jiang Yunfei stretched out his hand and pointed at Zhao Fan.

"Okay, okay. Zhao Fan, I am looking for you to handle the case, not for you to come and make trouble for me! ”

The staff on the side were completely stunned when they saw this situation.

Zhao Fan looked at the staff and said with a smile: "It's okay, it's okay, it's commonplace." ”

The staff smiled awkwardly from the sidelines.

"Well, go back an hour. I'll watch it more and rest well. Zhao Fan's appearance of a dead man not paying for his life made Jiang Yunfei's face flush with anger. Chen Zheng wanted to laugh on the side but didn't dare to laugh, so he could only hold back stiffly.

"You, you, you ......" Jiang Yunfei pointed at Zhao Fan speechless.

"Don't talk, I'll be talking for an hour." Zhao Fan turned his head, and while speaking, he blinked vigorously at Jiang Yunfei. Jiang Yunfei looked at Zhao Fan like this, and knew that he must have found some clues. I snorted very cooperatively, and found a place to sit down.

"Dude, were you also on duty on the day of the crime?" Zhao Fan asked unhurriedly.

"Yes!" The staff didn't feel anything wrong. Zhao Fan sat on the side thoughtfully.

"You're on the day shift, did anything unusual happen when you changed shifts that morning?"

"Anomaly?" The staff thought for a moment.

"Say something unusual...... Lao Wang was a little abnormal that day, after the shift change, he said that he would not leave anything, and he had to stay for a while. Say it's something important. ”

Jiang Yunfei stood up from the stool: "Who is Lao Wang?" Why didn't you say it when you came before! This startled the staff.

"Before...... No one asked, so I didn't think about it. Don't...... Did Lao Wang do this? The staff asked tentatively.

"Let me ask you who is the old king!" Jiang Yunfei stepped forward, his voice a few degrees higher.

"Lao Wang, Lao Wang is Wang Jianguo." The staff looked at Jiang Yunfei tremblingly.

"How old is he?" Zhao Fan asked on the side.

"I'm over fifty years old, hey~ You said that I am too, how can Lao Wang be a murderer at this age." The staff laughed awkwardly on the sidelines. Jiang Yunfei felt that there was a possibility.

"Where's the person?"

"In, at home." Jiang Yunfei stared at the staff, and the staff also reacted.

"Wait a minute, I'll look it up." The man hurried to look through the incumbent registration form.

"Found it, 202, Building 2, Guoya Community."

Jiang Yunfei turned around and rushed out!
