That's right, looking at the picture in the elevator monitoring, Li Li didn't bring the vegetables up that day, but she really steamed a pot of rice, if there are dishes in stock at home, in fact, Li Li should take out the dishes when steaming rice, but judging from the pot, Li Li doesn't seem to plan to cook.

If it is said that the meal has been eaten, then the rice in the rice cooker will not be as "complete" as it is now.

Qiao Chuan opened the refrigerator, and the wait in the refrigerator illuminated the scene inside the refrigerator as the refrigerator door opened.

Sure enough, there were several disposable lunch boxes in the freshness layer of the refrigerator, and the lunch boxes were full of dishes.

Qiao Chuan carefully took out one of the lunch boxes, the temperature of the lunch box was slightly cold through his gloves, according to the temperature of the refrigerator insulation layer, Qiao Chuan could judge from years of experience that this dish of stir-fried vegetables with shiitake mushrooms should not be stored for more than 5 days.

The packaging boxes of these dishes are the same, and it seems that this should have been purchased at the same time that day.

If these dishes were not bought by Li Li, then there is only one possibility, these dishes are the person who entered Li Li's room that day.

But at the same time, Qiao Chuan had a question.

There are no traces of these dishes and the pot of rice, which means that they did not plan to eat these meals, and at the same time, Li Li put these dishes in the refrigerator again, which shows that the murderer committed the murder after Li Li put these dishes in the refrigerator.

It can be seen that the person who brought these meals to Li Li at that time had already decided not to eat in this room at that time.

What was the reason why that man didn't eat here? Since Li Li has put the rice in the pot, it means that the two have made an appointment to eat in this room, so there must be something wrong with it.

Was that person the one who killed Li Li immediately after Li Li put the dishes away? That's why you didn't eat in this room?

It shouldn't be, Qiao Chuan tried his best to imitate the scene in his imagination, and he always felt that the scene he imagined just now was a little awkward.

If someone comes to eat at home, will you clean up the uneaten food while he is there, or will you clean up the uneaten food after he leaves?

Yes, when Li Li cleaned up these dishes, that person should have already left.

If it is still believed that the person committed the crime, then that person should enter the room again.

"Team Joe."

Qiao Chuan's thoughts were interrupted.

The criminal policeman in charge of surveying the walking ladder came in and made a simple report, and his report confirmed Qiao Chuan's thoughts.

There are two rows of relatively clear walking shoe prints on the walking ladder, and these two rows of shoe prints are very similar to the shoe prints found in the Huaizhi River at that time, and it can be basically judged that they were stepped on by the same shoes.

At the same time, based on the thickness of the dust on the shoe prints, it can be basically determined that the shoe prints were produced on April 19, the day before Li Li's body was found.

It seems that his guess is not wrong, the person who was in this room with Li Li had entered and exited the building on both sides on April 19, and he also entered and exited Li Li's room twice.

Once was to deliver food to Li Li and prepare to eat here, and once was to kill Li Li.

So, what was the reason for that person to turn back and kill Li Li, and then throw the body again, there must be some reason that has not yet been understood.

"Are there fingerprints on the handrails of the stairs?" Qiao Chuan asked the criminal police officer in charge of surveying the walking ladder.

The detective nodded.

"There are no traces of wiping on the handrails on the stairs, and the fingerprints on them are messy, but there are not many, and they are being investigated now."

Qiao Chuan nodded, and then asked:

"Are there any other peculiar traces found on the stairs?"

"Special traces?" The detective didn't understand what the special trace Qiao Chuan was talking about.

Qiao Chuan beckoned to the two people beside him and motioned for the two of them to come over, and the officer and Murong Yang Xue followed Qiao Chuan out of the room.

The sound of the pedals on the feet and the concrete of the walking ladder colliding with each other echoes in the stairwell, reverberating in the ears.

"Team Joe."

Xiao Cao was standing next to the cordon that had been pulled up and recording what should have been discovered by the criminal policeman just now.

Qiao Chuan nodded, pulled the cordon, and walked into the stairwell.

How did the murderer transport Li Li's body?

Qiao Chuan is thinking about this question now.

What would I do if it were me?

In order to avoid others from discovering it, I will hide Li Li's body in a "container", what is this "container"?

The container needs to meet the following conditions:

1. It's more convenient to pick up.

Qiao Chuan still remembers that in the autopsy report written by Chen Ru, the deceased Li Li weighed 45 kilograms and was 160 centimeters tall, and it was not easy to transport such a corpse.

2. It is not easy to be found suspicious by others.

This "container" must be one of the more common things, such as a large suitcase, which can easily fit an adult in.

At this time, Qiao Chuan remembered a case he had handled, which case was to use a trash can to transport a corpse, and the murderer was a cleaner, he used a trash can, put the body into it, and then passed through the elevator, no one would suspect that there was a corpse hidden in the trash can, which was to use the convenience of his profession.

But, obviously, that person will not be a cleaner, and a cleaner will not be able to support Li Li, let alone hide the body in the trash can, one is that Qiao Chuan did not find a large "container" in that period of surveillance, and the other is that it is very inconvenient to drag the trash can containing a corpse in the stairwell, and at the same time it will make people suspicious.

In addition to large suitcases, which are the more common "containers", what are the most common? I'm afraid not.

Qiao Chuan squatted in the stairwell on the fourth floor, and there was no trace of what he wanted.

Qiao Chuan looked around and fell on Murong Yang Xue's body.

Murong Yang Xue looked at Qiao Chuan's somewhat ill-intentioned eyes, and couldn't help but take a step back.

"Team Joe, what are you going to do?"

"How many pounds are you?"

"Me?" Murong Yangxue put her index finger on her lips and said with some embarrassment: "I'm more than eighty pounds." ”

"More than eighty pounds? That's pretty much it. ”

"It's almost ......"

Before Murong Yang Xue finished speaking, she felt a lightness in her body.

"Team Joe! What are you doing? ”

I saw Qiao Chuan stop and clamp Murong Yang Xue's body under his arm, Murong Yang Xue didn't know whether he was embarrassed or angry, and his face turned red.

"Don't move, cooperate with the case." Qiao Chuan just felt that something was wrong when he clamped Murong Yang Xue, what kind of more than eighty catties is this, this is estimated to be a hundred catties.

Murong Yang Xue didn't struggle anymore when he heard Qiao Chuan's voice, this Qiao Chuan, he didn't say a word before doing something.

When he arrived at the position of the staircase landing on the third floor, Qiao Chuan gently put Murong Yang Xue down.

That's right, it should be here.

Murong Yang Xue angrily hammered Qiao Chuan with a pink punch, Qiao Chuan didn't care about this punch, but squatted down.

Sure enough, you, like me, can't hold out here, so that the "container" is it.
