Tan Wan and Xia Zhiyue squatted in the corner, and Tan Wan reopened the surveillance video video.

The video started with Mr. Qian and Mrs. Qian sending their daughter back to the room, and it didn't take long for the two old men to come out after putting their daughter in the room, and Fang Wenyin entered the room two minutes later.

Then Fang Wenyin came out of the room, and at this time, according to Fang Wenyin's own confession, she listened to Qian Zhao'er's words and helped her go to the room to get warm clothes.

Ten minutes after Fang Wenyin left the room, the hotel staff pushed the cleaning and changing car twice, with an interval of about 15 minutes.

After the cleaning car passed twice, Zhao Yide entered the room, he entered the room for about two or three minutes, and ran out of the bridal preparation room like a ghost.

Within five minutes of Zhao Yide's departure, Fang Wenyin returned to the bridal preparation room with a blanket and scarf.

After that, she ran out of the room and eagerly pulled Xie Mowen and Tan Wan into the bridal room in the bathroom, and found that Qian Zhao'er had been stabbed to the ground, and the whole monitoring process was over.

"Look here."

Tan Wan pulled the progress bar of the surveillance video forward a few times until the linen cart passed by the door of the bridal room for the first time.

Tan Wan paused the video: "Zhiyue, you see, the linen wheels are sunk into the depth of the carpet."

The hallways of high-end hotels are covered with thick carpets, and if you walk on them in high heels, you will clearly feel the heels sinking into the carpet.

In the same way, when the hotel staff pushes the cleaning cart past, the wheels of the cleaning cart will also form different dents due to the different weights in the vehicle.

Before the car passed by the door of the bridal room for the first time, the wheels were visibly deep in the carpet.

But after passing through the door of the bridal preparation room, the wheels of the car did not continue to sink deeply, and even the strength of the cleaning staff was reduced a little.

The second time the car passed by, it was the opposite of the first.

Before the car passed the door of the bridal room for the second time, the weight of the car was not very heavy, but after passing through the bridal room, the car was heavier.

When they checked the surveillance before, they only noticed whether anyone other than the murderer had entered the room, and their eyes were always fixed on the number of people, and they didn't notice the change in the weight of the cleaning car twice.

The monitoring distance is long, the angle is tricky, and the picture is not high-definition.

It's really hard to spot unless you look very carefully at the state of the wheels.

"The little boy just hit the hospital's warming car, and I thought that there was such a way to go unnoticed."

Tan Wan continued, "What if the murderer hid in the cleaning car in advance, got out of the car when the car was blocked at the door and blocked the surveillance, killed the person, and then did it again, and used the cleaning car to leave in the same way?" ”

Xia Zhiyue listened carefully, although this method sounded very unreliable, it was indeed possible.

But there is another question, Xia Zhiyue has to be more serious: "Didn't the cleaner of the cart find out about the difference in the weight of the cart in this process?" ”

"The cleaning car itself is very tall and big, and it is easy to jam people's vision, even if the cleaning staff feels strange afterwards, they should not think that there will be a person hidden in their car.

To confirm this, just ask the cleaning aunt in the surveillance video, and it will be clear. ”

Xia Zhiyue nodded, and immediately got up to leave: "I'll let Ade go back to the hotel!" ”

"No, you don't." Tan Wan stretched out his hand and grabbed Xia Zhiyue, "I'll ask Xie Mowen to ask, so as to save time."

Moreover...... We've got to stay here, we can't leave yet. ”

This writer Xie and Officer Tan came to the banquet together, the two are good friends, it is not difficult to ask the writer to investigate some things, Xia Zhiyue can still understand.

But she didn't know why they had to stay here.

Xia Zhiyue asked, but Tan Wan didn't say it directly, but just called Xie Mowen, quickly explained their situation in the hospital, and then hung up the phone.

hung up Xie Mowen's phone, and while waiting for him to reply, Tan Wan inadvertently glanced at the door of Qian Zhao'er's ward.

Originally, Fang Wenyin came out with the two of them, but she disappeared at this time.

"Where is Fang Wenyin?" Tan Wan suddenly asked in a hurry, and his eyes kept searching around.

Xia Zhiyue didn't know: "I was still here just now, did I go to Qian Zhao'er's ward?" ”

In the ward, Qian Zhao'er lay quietly on the hospital bed and fell asleep, and Mrs. Qian sat beside her daughter's bed with her back to the door, knitting a sweater peacefully.

The family stayed in the room quietly for many years, and there was no figure of Fang Wenyin.

It just so happened that Xia Zhiyue had interrogated Fang Wenyin before, and there was her contact information in her mobile phone, so she tried to call her.

Fang Wenyin's mobile phone immediately emitted a prompt tone of 'The other party is turned off, please dial again later'.

When Tan Wan heard this, his heart gradually revealed uneasy emotions, which quickly climbed to his face and showed naked in front of Xia Zhiyue.

Fang Wenyin's sudden disappearance is not a good thing, especially in this situation.

She was preoccupied, and her steps gradually quickened, and she began to search the hospital floor.

Tan Wan's eagerness to try to find Fang Wenyin soon affected Xia Zhiyue.

Xia Zhiyue also hurriedly followed behind Tan Wan, seeing that she was suddenly panicked, she was also infected by this emotion, and quickly trotted behind Tan Wan: "What are you anxious about??" ”

I didn't want to talk about it late, but I was looking for someone by myself.

It wasn't until the two of them ran through the entire inpatient department and didn't see Fang Wenyin that Xia Zhiyue finally couldn't help it.

She was out of breath, and she felt that she couldn't keep up with the pace of talking: "You, what the hell are you anxious about!" ”

Tan Wan was dragged by Xia Zhiyue, she was also so tired that she was panting, and finally didn't hide it: "...... I suspect Fang Wenyin, it is very likely that Fang Wenyin assassinated Qian Zhao'er. ”

"You doubt her?" Xia Zhiyue crossed her waist and half bent over to pant, and looked up at Tan Wan suspiciously.

Fang Wenyin, a girl who is soft and weak, wore a pink and tender bridesmaid dress at the wedding, and she is a delicate little beauty, just looking at her appearance, she doesn't look like a murderer.

"Just Fang Wenyin's thin arms and legs, have the strength to assassinate?" Xia Zhiyue relieved herself and stood up straight, "You and I know very well what we do, stabbing and killing people is not such a simple thing.

The bones and muscles of the human body make the knife resist when it enters the body, and it takes a lot of force to do it.

This is a little girl, I see that she can't lift her hands or carry her shoulders, and it is estimated that she has never even killed a pig, how can such a person kill people? ”
