Why do I have this thought? Qiao Chuan thought to himself.

The thought flashed through his mind, and when he tried to find out why he had the idea, he never got to the source.

Why are the floors so clean? Qiao Chuan got up and took a step back, letting the people from the technical department prepare to survey the pedals to enter, but he was thinking about the problem outside the door.

The cleanliness of this floor was obviously carefully wiped, and he recalled the elevator monitoring of Building 15, in the surveillance video, no one except Li Li took the elevator to the 4th floor, since there was a shoe print on the stairs that went up to the fourth floor, and the shoe print was consistent with the shoe print at the scene, it was basically determined that the owner of the shoe print was the person who entered Li Li's room.

In other words, that person is the most suspicious, the number one suspect.

But the man seemed to ignore the shoe prints in the staircase, and there were such obvious shoe prints.

But the room is so clean, Li Li is only one person in this room except Li Li can clean.

That's the killer himself.

It's strange that these two phenomena get two completely different people.

One person had extremely strong anti-reconnaissance capabilities, and the other ignored the traces left at the scene.

Unless the murderer had some accident in the stairwell while carrying the body, so that he didn't have time to deal with the shoe prints left in the stairwell, or did the murderer not want to deal with the shoe prints in the stairwell at all?

How is that possible? Qiao Chuan shook his head, since he cleaned the floor of Li Li's room so cleanly, he should be able to deal with the shoe prints in the stairwell.

Maybe it's just that I complicated the murderer, or maybe the murderer just learned to deal with the traces in the room from TV or novels, and the traces in the stairs are basically not mentioned in these works.

What kind of murderer will this be, judging from the two scenes, this murderer has a certain anti-reconnaissance ability.

Judging from throwing corpses and avoiding surveillance, he has strong observation and logical thinking skills.

At the same time, in such a short period of time, he can think of what work needs to be done in the future, how to dispose of the corpse, and where to throw the corpse, it seems that this person is calm and familiar with Sancao City.

What kind of person will he be?

"Team Joe."

A voice interrupted Qiao Chuan's thoughts.

"Huh?" Qiao Chuan turned his gaze to Xiao Cao, who spoke.

Xiao Cao pointed to the ground, only to see that a lock on the ground was dismantled and torn apart, Qiao Chuan looked at a hollow hole in the door, and he understood that Xiao Cao had dismantled the lock from the door.

"Exclusion of technical unlocking."

Qiao Chuan nodded, since the technical unlocking has been ruled out, it means that either Li Li opened the door for the murderer, or the murderer opened the door with the key.

There are three people from the technical department of the criminal police team, one of whom is responsible for collecting evidence and records, and the other two are responsible for the investigation of the scene, which is Qiao Chuan's consistent style of being in charge of the case, he doesn't like to bring too many people, he feels that bringing too many people is not conducive to the protection of the scene and the investigation of the scene.

A pedal passage was laid out, Qiao Chuan put on the pedal shoes that the police had just purchased and entered the scene, Qiao Chuan liked this kind of pedal shoes very much, this kind of pedal shoes are composed of shoe boards, shoe loops, and brackets, for indoor investigation, this kind of pedal shoes are more beneficial to the protection of the scene than other ways to enter the scene.

The sound of pedal shoes on the hardwood floor like clogs was slightly eerie in this empty room.

The layout in this house is a little decent, if it weren't for a group photo of Li Li on the bar in the living room, Qiao Chuan really doubted that he had entered the wrong room.

Qiao Chuan picked up this photo, there are three people in the photo, the background behind the three people should be the tourist attractions in Suzhou and Hangzhou, and it can be seen from the Leifeng Pagoda behind that this is the West Lake of Hangzhou. There are two familiar figures in the photo, one is Li Li, and the other is Liu Yan, the general manager of the "Royal One Mansion".

Qiao Chuan put down the photo and looked around, the structure of the whole room has two bedrooms, a dining room, a kitchen, a bathroom, and a kitchen, and the area of the whole room is about 100 square meters.

Qiao Chuan walked to the kitchen.

The kitchen stove looks very clean, and the kitchen utensils and condiments on the stove are all available. The rice cooker on the stove is still plugged in, look at the time displayed above, the time displayed above is very accurate, Qiao Chuan silently calculated, according to the above time calculation, the time when this pot of rice began to steam was more than 7 pm on April 19th, Qiao Chuan opened the lid of the rice cooker, and a pungent burnt smell came to his nose, and the rice on the top was already a little shriveled.

Qiao Chuan glanced at the scale where the rice arrived, so much rice should be more than the amount of food for two people. He closed the lid of the rice cooker and asked Murong Yang Xue to come over and take pictures to record.

Murong Yang Xue didn't know what to do for a while with the camera in his hand, although he was from the police academy and had listened to a lot of courses, but when he actually arrived at the scene, he forgot the theories he heard in class.

Qiao Chuan glanced at Murong Yang Xue who was struggling and pointed to the rice cooker next to him.

"What we need to know is the whereabouts of the deceased, including all the things she did during her lifetime, whether it has anything to do with this incident or not."

"After all, we don't know if this has anything to do with the whole incident." Murong Yang Xue replied.

Qiao Chuan was stunned for a moment, and then a faint smile appeared on his face.

This sentence was still when Murong Yang Xue was still a student, Murong Yang Xue listened to Qiao Chuan, and Qiao Chuan's lecture made Murong Yang Xue a fan of Qiao Chuan.

What did the deceased do before his death, Murong Yang Xue's brain was running rapidly, and she tried her best to incarnate herself as Li Li: At that time, I walked into the elevator, pressed the fourth floor, then walked out of the elevator, opened the door, and steamed a pot of rice...... A pot of rice was steamed...... How much should I steam?

Murong Yangxue opened the lid of the rice cooker: Ao, at least for two people, it turns out that I steamed this rice to wait for one person......

Wait, it seems that something is missing, steamed rice, what about the dish? I didn't bring the food with me! I wasn't going to cook, was that the person who brought the food?

But what about the dish?

Murong Yang Xue walked out of her imagination, and she walked to a place with the camera in her hand.

"Did you think of that?"

Murong Yang Xue looked at Qiao Chuan's eyes and nodded.

"That guy is right in there."
