This morning, Lan Feng immediately retrieved the surveillance video of Qin Jiangkai's residential area.

"At 10:16 am on the 11th," Lan Feng called out a video image: "The victim Ruan Xiaoqing walked into the Xingfuyuan community, the elevator of Unit 2 of Building 15."

Surveillance cameras are installed inside the elevator.

At 10:16, the elevator opened, and the floor display was the 11th floor.

Ruan Xiaoqing appeared on the screen alone.

A white down jacket with a large plush earmuff.

Black cotton socks, a new pair of boots.

"The video was shot from above, so Ruan Xiaoqing's face was not completely captured."

"However, I have taken a screenshot of the video for Lin Sisi and Ruan Xiaoqing's other two roommates to identify."

"From the perspective of body and hairstyle, it should be Ruan Xiaoqing."

Chen Yan nodded, this was basically confirmed.

Ruan Xiaoqing walked into the elevator, perhaps because the weather was a little cold, so she took off her gloves and kept her hands warm.

There is a ring on the ring finger of his right hand.

Chen Yan compared what was in his mind and found that the ring at the scene of the severed finger was exactly the same.

"However," Lan Feng pointed at the figure in the video with a puzzled face: "After Ruan Xiaoqing left the elevator, he did not appear at the gate of the community."

In addition to Chen Yan, Liu Biao, Liu Qingshan and others were also listening to Lan Feng's report.

According to Lan Feng's investigation results, if Ruan Xiaoqing did not appear at the gate of the community, where did she go?

Everyone knows the layout of the entire community. There is only one entrance and exit at the front door.

It is the only way for all pedestrians to enter and leave the community.

So, did Ruan Xiaoqing drop something and return to Qin Jiangkai's house again?

Liu Qingshan asked this question.

However, Lan Feng shook his head: "My first reaction was the same."

"However, I checked the elevator surveillance after that, and I didn't find any video of Ruan Xiaoqing taking the elevator back again."

"The elevator at that time... Was there a temporary failure, or for some other reason, Ruan Xiaoqing went up the stairs?"

"This..." Lan Feng pondered for a moment: "The elevator failure should not exist."

"Because the video I was viewing was continuous, there were always people in and out of the elevator, and it was always running."

"As for whether Ruan Xiaoqing took the stairs..."

"It's not certain yet."

Not really sure.

In the community where Qin Jiangkai lives, in each unit, only the elevator has surveillance cameras.

However, there are no cameras installed in the corridor and near the entrance door.

If Ruan Xiaoqing took the elevator out of the unit at that time, and then took the stairs to return to Qin Jiangkai's house, Lan Feng would definitely not have been able to find it through the video.

but……

Chen Yan shook his head: "The possibility of this is very small."

"Everyone, pay attention to Ruan Xiaoqing's dress."

"In the daytime on the 10th, after Qin Jiangkai and Ruan Xiaoqing met, they bought Ruan Xiaoqing clothes, shoes and bags at the mall."

"And the clothes Ruan Xiaoqing wears in the video are very new, without any wrinkles."

"It should be the new clothes Qin Jiangkai bought for her... Pay attention to the leather boots she wears."

"It's high-heeled boots," Chen Yan said, while Lan Feng on the other side enlarged the picture: "And when the elevator did not malfunction, Ruan Xiaoqing climbed the stairs wearing high-heeled boots and returned to the 11th floor..."

"It's very unlikely."

"It doesn't make sense."

"Moreover, in the video, Ruan Xiaoqing didn't turn over the bag, which means that at least she didn't find anything left in the elevator."

Chen Yan's analysis is very reasonable.

Climbing 11 floors of stairs wearing high-heeled boots is really unlikely.

"All, after Ruan Xiaoqing walked out of the unit building, it is very likely that he did not return to Qin Jiangkai's house."

"But," Lan Feng's eyes were full of doubts: "Where can she go?"

"In this community, there is only one exit, and the exit has a high-definition camera."

"I have checked the footage from this camera for three days."

"However, no trace of Ruan Xiaoqing was found."

"As for the other exit, I also sent someone to check, and there is no trace of Ruan Xiaoqing."

"She can't just disappear out of thin air, can she?"

Lan Feng's investigation was very meticulous.

After discovering that the video at the gate did not capture Ruan Xiaoqing's trace, Lan Feng did not let go of the surveillance at the exit.

The community where Qin Jiangkai lives is quite upscale.

People and vehicles are separated.

There is one entrance on both sides and one after exit.

Vehicles circulate in and out of the community in one direction.

Of course, the community has not achieved complete separation of people and vehicles.

In the yard, there are both underground parking garages and above-ground parking spaces.

Vehicle exits, although it is stipulated that only vehicles can travel, but there are also individual pedestrians going out from vehicle exits.

All, Lan Feng did not miss the exit of the vehicle, even the video of the entrance of the vehicle, he retrieved it.

However, there was still no trace of Ruan Xiaoqing.

"Check other monitoring in the community."

Chen Yan pointed to the vehicle exit of the community: "After Ruan Xiaoqing left the unit building, there are only two possible places to go."

"The first is to return to Qin Jiangkai's residence."

"Although there is no evidence to support this point, if Ruan Xiaoqing really climbed the stairs and returned to Qin Jiangkai's house for some special reasons that we don't know, it is not impossible that he was killed."

"So, immediately organize a search of Qin Jiangkai's residence."

"Secondly, here in Lanfeng, we must screen all the monitoring in the community."

"Including the underground garage of the community, and the video of the road on the ground, it must be checked again."

"Ruan Xiaoqing can't disappear out of thin air, we must find her trace."

...

Happy Garden Community.

Chen Yan personally came to search Qin Jiangkai's residence.

If Ruan Xiaoqing really returned to Qin Jiangkai's residence through the stairs, then Qin Jiangkai's residence might be the first scene of the crime.

According to Ruan Xiaoqing's degree of wetness, in any case, it is impossible for the murderer not to leave clues at the scene of the crime.

For example, the smell of blood, such as the taste of ostrich meat after cooking.

Of course, the time of Ruan Xiaoqing's death, the autopsy results determined that it was around December 12.

A week has passed since today.

If the site is not airtight, the smell has been difficult to retain.

However, with Chen Yan's ability to unlock the olfactory gene lock, there will definitely be some different discoveries.

Room 1101, the first time the door was opened, Chen Yan opened the lock of smell and vision genes.

The room was neat and clean.

Chen Yan snorted and went straight to the kitchen.

Qin Jiangkai's home is very large, with an area of ​​about 180 square meters.

All in all, the kitchen area will be much larger.

However, after entering the kitchen, Chen Yan frowned slightly.

Nothing **** or anything else.

Although the whole kitchen has traces of use, it can be clearly seen that it has not been used many times.

Opening the cabinet, Chen Yan took out a set of knives.

It is a double brand of knives.

Careful observation, the blade is sharp, but there is no blade burr generated by cutting bones.

These tools are used very rarely.

Open the refrigerator, there are some fruit, there are some popsicles in the freezer, but no meat.

Also, there is no frozen meat and no hoarfrost on the case.

smell……

Similar to the smell of a new refrigerator.

Preliminary conclusion, no meat has been frozen in the refrigerator.

Leaving the kitchen, in the bedroom, the quilt was not folded.

Last night, when Qin Jiangkai was taken to the detective team, it was already midnight.

At that time, they were already asleep.

Because it was winter, the windows in the bedroom were closed, so the smell did not dissipate.

In addition to what Chen Yan knew, the smell on Qin Jiangkai's body, there were three other different smells in this bedroom.

Moreover, they are all recent smells, which are relatively light.

It seems that this Qin Jiangkai, in addition to having contact with Ruan Xiaoqing recently, has also come to play in this bedroom with at least two other people.

Of course, it is impossible to tell if it is a male or female Chen Yan.

But it must be at least two people.

Half an hour later, Chen Yan led the team to leave.

Qin Jiangkai's home, there is no problem.

At least, not the first scene of the crime.

Back to the detective team, it is noon.

The investigation on Lan Feng's side has yet to result, and Chen Yan watched the video that Zhao Bing brought back from the technical college.

The videos are indeed as Zhao Bing said, most of them are blurry.

However, the video of the school gate and the parking lot is relatively clear.

From the afternoon of the 11th, Chen Yan began to watch the video.

Chen Yan is carefully observing every car entering the campus Judging from the current information, Ruan Xiaoqing disappeared at 10:16 am on the 11th, after walking out of the elevator of the unit building of Xingfuyuan Community, on the 12th. death around.

On the evening of the 15th, the corpse Suichou appeared in the Vocational and Technical College.

Therefore, Ruan Xiaoqing's body was brought into the campus after being frozen, and then lost and soaked in the school.

Or did the killer do all this off campus and then bring the corpse object into the campus?

These are all possible.

Because the campus area is small and there are few parking spaces, the school's vehicle entry and exit management is relatively strict.

Entry and exit of external vehicles are required to be registered.

In view of this, Chen Yan hopes to find some clues about the entry and exit of vehicles at the gate.

At 5:00 pm, it was already dark.

Chen Yan is also viewing the video materials in the office.

From the afternoon of the 11th to the evening of the 17th, Chen Yan had basically watched the video at the gate.

However, still nothing.

These days, although foreign vehicles need to be registered, they are just a mobile phone number, who to look for, and when to leave.

Then, for the unrecorded cars, the school security also cleaned up at night.

As for the internal vehicle, it is a state of free passage.

There is no obvious doubt in the video.

Rubbing his sour eyes, Chen Yan stretched.

boom!

The office door suddenly opened.

Chen Yan raised his head, it was Lan Feng.

At this moment, Lan Feng was in a hurry, but there was a look of joy on his face.

Holding a hard disk in his hand, he gestured towards Chen Yan excitedly.

"Boss! There is a major discovery!"
