Only knowing Yi Ziyun's commuting time can he commit crimes. "

Yu Shi took a general look at the surrounding environment, and then took Li Yu to find the person in charge of the mall to check the monitoring.

When the person in charge of the shopping mall heard Yushi, the two identified themselves, took them into the background monitoring, and asked, "When exactly do you want to watch?"

"Let me take a look at No. 23 first. There is a bench a little outside the clothing store. Can your surveillance camera see that bench?" Yu Shi made a gesture, and the person in charge of the mall immediately understood.

"It's the place in the southeast corner. This is the second time I've turned on this monitor today." The person in charge of the mall instructed his subordinates to select the monitor record.

Li Yu asked casually, "Is there anyone else who has seen the same monitoring today?"

"Well, a female customer said that the bag was left on that bench two days ago." After the person in charge of the mall finished speaking, the monitoring just turned on.

"Why are you only here now to look for the one from the past two days?" Yu Shi doubted for a moment, she had an intuition that that person was not just looking for bags.

"I don't know about that. Since she said it was lost, I had no choice but to show it to her. She didn't find it after reading several times."

Yu Shi nodded, and Li Yu and Li Yu focused on watching the surveillance, the screen was playing at several times the speed, and the two of them just stared at whether anyone was sitting on that bench. A fat man with a mask and wearing black clothes took a newspaper, sat on the bench, and then began to read the newspaper. He sat there until nearly ten o'clock before leaving. Yu Shi asked the person in charge to broadcast Several days of monitoring, although the time is not fixed, but the man will sit there and read the newspaper at different times every time.

"Manager, please help me copy these tapes."

Li Yu immediately understood after Yu Shi's eyes signaled that the man in the picture was weird.

Yu Shi called Baa Baa and asked her to ask if No. 20 Yi Ziyun was at work, but she finally got the answer no, she turned to Li Yu and said, "This man is definitely observing Yi Ziyun." Yun, he sat down on the NO.20 tape for a while and left, it was because Yi Ziyun was on vacation that day."

Of course, she didn't just judge that the man was observing Yi Ziyun because of this reason. The man never came to the mall after Yi Ziyun's death, and she observed that the layout and typesetting of the cover of the newspaper that the man brought every day were the same. , the man reads the same newspaper every day, and the newspaper is opened on his lap, and he flips it occasionally. Although it is not obvious, his face is also looking in the direction of the clothing store. The newspaper is just a prop for him. Make people doubt him.

Although he ran into the mall to read the newspaper, this is already the most strange thing.

Afterwards, the road to collect the confessions of the big man and Baa Baa came to an end. Judging from the confessions of his colleagues, Yi Ziyun has not had conflicts with others recently, and he is also a normal person. He commutes to and from work on time and works hard. , a person with such a good character was killed for no reason, colleagues and bosses feel sorry.

"A key point is missing..." Li Yu was puzzled.

Colleagues said that Yi Ziyun was very popular and never made enemies with others, but there must be some factors in the prisoner's choice of Yi Ziyun as the target. A word, a movement, or even a look may be the reason for the murder .

"Maybe there may be conflicts with someone in a place that others don't know, and Yi Ziyun is not always accompanied by someone." Looking back, we can ask the technical department to process the monitoring screen.

Walking out of the main entrance of the shopping mall, Yu Shi observed the surveillance cameras on the street and asked Li Yu to note down the location. These surveillance cameras will be applied for review later, and there is a chance to take pictures of the suspect's face.

Bringing the big man and Baa-baa, Yu Shi was going to Yi Ziyun's house to take a look, so he asked Li Yu to go back to the police station with Baa-baa, while he and the big man set off for Yi Ziyun's house.

Yi Ziyun lived with his parents in a ten-year-old apartment on the fifth floor. When they came to the house, they led people to Yi Ziyun's room and let them check it out. People from the department have already been there, and everything that should be taken away has been taken away. Yu Shi just wanted to take a closer look, and there might be some unexpected discoveries.

Yi Ziyun's room is very tidy. Yi Ziyun's parents said that her daughter has been very self-disciplined since she was a child. The room has never been messy since she was a child. Everything is very neatly arranged, even a pen is arranged horizontally. Yes, so Yi Ziyun sorts out the clothes in the clothing store, because they look neat and beautiful.

"Isn't this a bit of obsessive-compulsive disorder? Except for soldiers, I haven't seen anyone fold the quilt into tofu cubes when they wake up."

The big man couldn't help complaining, and even the bed sheets were made very smooth, without any wrinkles.

"Will you do this?" Yu Shi opened the desk drawer and glanced at the contents.

"That's why I changed from a soldier to a criminal police officer. I'm very casual and I can't adapt to that kind of life." The big man thought of his home, which was as messy as possible, and the quilt was never tidied. "Are you self-disciplined?"

"Not self-disciplined." Why do people restrain themselves so much?

As soon as he finished speaking, Yu Shi's cell phone rang, and it was the call from the forensic doctor Shu Xia, "Yu Shi found a new discovery in the fibers found between the teeth and nails of the corpse, and analyzed trace amounts of some components including sucrose, fructose, and glucose. , glutamic acid, serine..."

Yu Shi heard that the other party seemed to be planning to read all the ingredients, so he quickly interrupted and said, "I can't understand if you read it any longer. If there is sucrose in the ingredients, is it sugarcane?"

"That's right, it should be sugarcane, or a processed product made from sugarcane." Shuxia gave a firm answer.

Yu Shi thought that she saw something similar when passing the kitchen just now, so she walked quickly to the kitchen. There were a few sugar canes on the table. She asked Yi Ziyun's parents and found out that they were bought by Yi Ziyun a few days ago. , After telling Shuxia about this, Shuxia said excitedly: "Bring it back."

As soon as he hung up the call of the forensic doctor, another call came right away. Yu Shi looked at the caller ID, it's rare!

"Hello flower team."

"Hey Team Yu, there is good news or bad news, which one do you listen to first?" Hua Yicheng asked on the other end of the phone.

Hua Yicheng is the captain of the criminal investigation team next door, also Xiaoliang's boss.

"Bad news!" Yu Shi pointed at the sugarcane, motioning for the big man to take it away.

"Our team received a murder case yesterday." Hua Yicheng was standing in his office at the moment, holding the autopsy report sent to him by the forensic doctor.

To be honest, I was a little surprised when I was talking about it. This murder happened too frequently, and I don't know why Hua Yicheng called her to tell her, "What's the good news?"

"The forensic doctor found fibers on the body. After examination, it was found to be the same as your group's body. Congratulations to your group for filing the serial murder case."
