Tan Wan and Xia Zhiyue squatted in the corner, and Tan Wan opened the surveillance video again.
The video started playing when Mr. Qian and Mrs. Qian sent their daughter back to the room. The two elderly people came out not long after putting their daughter in the room. Fang Wenyin entered the room two minutes later.
Then Fang Wenyin left the room. According to Fang Wenyin's own confession, she listened to Qian Zhaoer and helped her get warm clothes from the room.
Ten minutes after Fang Wenyin left the room, the hotel staff passed by twice with a cleaning and washing cart, with an interval of about fifteen minutes between the two times.
After the cleaning truck passed by twice, Zhao Yide entered the room. He entered the room for about two or three minutes, and ran out of the bride's preparation room as if he had seen a ghost.
Not five minutes after Zhao Yide left, Fang Wenyin returned to the bride's preparation room holding a blanket and scarf.
After that, she ran out of the room and eagerly pulled Xie Mowen and Tan Wan who were in the bathroom into the bride's room. She found Qian Zhaoer stabbed to the ground, and the entire monitoring process ended.
"Look here."
Tanwan pulled the progress bar of the surveillance video forward a few times until the linen cart passed the door of the bride's room for the first time.
Tan Wan paused the video: "Zhiyue, look, the wheels of the linen cart have sunk deep into the carpet."
The aisles of high-end hotels will be covered with thick carpets. If you walk on such carpets wearing high heels, you will obviously feel that your heels sink into the carpet.
In the same way, when hotel staff push a cleaning vehicle by, the wheels of the cleaning vehicle will also be dented to different degrees due to the different weights inside the vehicle.
Before the car passed the door of the bride's room for the first time, the wheels were obviously deeply dented in the carpet.
But after passing the door of the bride's preparation room, the wheels of the car did not sink further, and even the cleaning staff's pulling force became lighter.
The situation when the car passed by again for the second time was opposite to the first time.
Before the car passed the door of the bride's room for the second time, the weight of the car was not very heavy. On the contrary, after passing the bride's room, the car became heavier.
When they checked the surveillance earlier, they only noticed whether anyone other than the murderer entered the room. They kept their eyes on the number of people and did not notice the two changes in the weight of the cleaning vehicle.
The surveillance distance is long, the angle is tricky, and the picture is not high-definition.
It's really hard to spot unless you look carefully at the condition of the wheels.
"The little boy just hit the hospital's insulated truck, and it occurred to me that there is such a way to not be noticed."
Tan Wan continued, "What if the murderer hid in the cleaning truck in advance, got out of the car when the car was blocked at the door and blocked the surveillance, killed the people, did it again, and used the cleaning truck to leave in the same way?"
Xia Zhiyue listened carefully. Although this method sounded very unreliable, it was indeed possible.
But there was another question, and Xia Zhiyue had to be more serious: "Didn't the cleaning staff of the cart notice during this process that there was a difference in the weight of the cart?"
“The cleaning truck itself is very tall and can easily block people’s vision. Even if the cleaning staff felt strange afterwards, they probably wouldn’t have thought that there was a person hiding in their car.
To confirm this, just ask the cleaning lady in the surveillance video and it will be clear. "
Xia Zhiyue nodded and immediately stood up to leave: "I'll let Ade go back to the hotel right now!"
"No need." Tan Wan reached out and held Xia Zhiyue, "I asked Xie Mowen to ask, so as to save time.
Besides...we have to stay here, we can't leave yet. "
Writer Xie and Officer Tan came to the banquet together, and they were on good terms with each other. It would not be difficult to ask Writer Xie to investigate some matters, and Xia Zhiyue could understand it for the time being.
But she didn't know the reason Tan Wan said they had to stay here.
Xia Zhiyue asked, but Tanwan didn't say anything directly. He just called Xie Mowen, quickly explained their situation in the hospital, and then hung up the phone.
After hanging up the phone with Xie Mowen and waiting for his reply, Tan Wan inadvertently glanced at the door of Qian Zhaoer's ward.
Fang Wenyin originally came out with them, but now she disappeared.
"Where is Fang Wenyin?" Tan Wan suddenly asked in a hurry, his eyes constantly looking around.
Xia Zhiyue was not sure either: "You were here just now. Did you go to Qian Zhaoer's ward?"
In the ward, Qian Zhaoer lay quietly on the bed and fell asleep. Mrs. Qian sat by her daughter's bed with her back to the door, knitting a sweater peacefully.
The family spent time quietly in the room, with no sign of Fang Wenyin.
It happened that Xia Zhiyue had interrogated Fang Wenyin before and had her contact information on her phone, so she tried to call her.
Fang Wenyin's cell phone immediately sounded the tone of 'The other party is turned off, please call again later'.
When Tanwan heard this, he gradually felt uneasy in his heart, and this emotion soon crawled onto his face, nakedly displayed in front of Xia Zhiyue.
It's not a good thing for Fang Wenyin to disappear suddenly, especially under such circumstances.
She was worried, and her steps gradually became faster, and she began to search the hospital floors.
Tan Wan's eagerness to find Fang Wenyin soon affected Xia Zhiyue.
Xia Zhiyue also hurriedly followed Tan Wan. Seeing her sudden panic, she was also infected by this emotion, and trotted after Tan Wan: "What are you in a hurry for??"
I didn’t really want to talk about it when we talked about it earlier, so I just kept looking for someone.
It wasn't until the two of them searched the entire inpatient ward without seeing Fang Wenyin that Xia Zhiyue finally couldn't bear it anymore.
She was panting and felt like she could hardly keep up with Tan Wan: "What are you in a hurry for?"
Tan Wan was dragged by Xia Zhiyue, and she was so tired that she breathed heavily, and finally confessed: "...I suspect Fang Wenyin. It is very likely that Fang Wenyin assassinated Qian Zhaoer."
"Do you doubt her?" Xia Zhiyue panted with her hands on her hips, looking up at Tan Wan with a suspicious look on her face.
Fang Wenyin is a delicate girl. She wore a pink bridesmaid dress at the wedding. She looked like a delicate little beauty. In terms of appearance, she didn't look like a murderer.
"Does Fang Wenyin have the strength to stab someone with her thin arms and legs?" Xia Zhiyue regained her breath and stood up straight, "You and I both know very well in this business that killing someone with a knife is not that simple.
Human bones and muscles will create resistance when the knife enters the body, and it requires a lot of force.
This is a video of a little girl. I saw that she couldn’t lift it with her hands or carry it on her shoulders. She probably had never even killed a pig. How could such a person kill someone? "
