"Ah, here I come."
Tan Wan heard Wang Mei calling him and hurriedly ran to catch up.
As she ran, she thought that she had to ask Li Dongliao to bring someone from the identification department to see if there were fingerprints of the deceased Liu Xiaoyan on the sink.
The murderer may wear gloves, but Liu Xiaoyan, the victim, does not.
If Liu Xiaoyan was really drowned in the mop sink by the murderer, then when she struggled, she would have used her hands to support the edge of the sink to fight against the murderer.
The sink was made of iron and it was easy to detect fingerprints, even if the murderer wiped all sides of the sink.
Even if fingerprints cannot be detected, hair or other things matching Liu Xiaoyan's DNA can still be detected in the sewer.
Since the murderer can enter and leave the orphanage at will without arousing suspicion, there is only one possibility for the murderer.
The murderer is in the Red Heart Orphanage.
Liu Xiaoyan and Gao Meizi are not tall and strong, so the murderer may not be a man, but also a woman.
Is it among the employees who have been laid off, or is it...
Tanwan thought of this and turned his attention to Wang Mei, who was leading the way in front of him.
Tan Wan suddenly said: "Teacher Wang, what is the room where Dean Gao passed away used for?"
"Why do you ask this?" Wang Mei was obviously wary of this question and did not answer directly.
“Although there was a lot of dust in the room, the mattress and urinal showed obvious signs of use.
Although the room is occupied, the door is locked. Isn't this strange? "
Wang Mei looked back at Tan Wan: "Officer Tan already has the answer in his mind, why do you have to ask me again?
But only two people in the orphanage have the key to that door. How did Officer Tan know there was a mattress inside? "
She looked at Tan Wan behind her in confusion, and after thinking for a while, she suddenly realized it, and burst into laughter.
"I know! You must have pried open the door lock! That day Gao Miko came to me angrily and asked me why I opened the door for you. I was still confused and didn't know what happened.
It must be, it must be you and the male police officer who knocked on the door that day. What method did you use? "
Wang Mei changed her previous aloofness and showed a strong interest in this issue, staring at Tan Wan with her eyes.
Tan Wan knew there was nothing to hide, so she told Wang Mei her method of using cans to unlock the door.
After hearing the method, Wang Mei smiled: "Interesting."
After she said this, she quickly returned to her previous cold expression, turned her head and continued walking forward.
Wang Mei knew much more about the orphanage than Tan Wan thought.
From her words, Tan Wan was also convinced of her doubts. Children in the orphanage might indeed be abused or imprisoned.
Wang Mei didn't feel Tan Wan's gaze and continued to lead the way.
"Teacher Wang, when did you start working in the orphanage?" Tan Wan asked again.
"This question seems to have been answered just now." Wang Mei continued, "It's been a long time and I don't remember it."
"You're not completely impressed, are you? Think about it again?" After Tan Wan finished speaking, she felt that she had asked too directly.
In order to avoid Wang Mei's suspicion, Tan Wan added: "I'm just curious. You look very young, but you know very well what's going on in the orphanage.
After Dean Gao Miko passed away, you took over the orphanage. It seems that Dean Gao trusted you and handed you the key a long time ago. It seems that she trusted you during her lifetime. "
At this point, Wang Mei suddenly interrupted Tan Wan: "Six years."
Wang Mei answered quickly. Tan Wan didn't react and didn't hear clearly: "What?"
"I just remembered, I have been working here for six years." Wang Meliso replied.
She answered quickly. Usually when people don't know their length of service, most of them will answer "I have been doing this for about five or six years", or "About six years or so".
But Wang Mei remembered it very clearly and immediately reported her length of service to Tan Wan.
It's not like she said that she can't remember the time she worked.
Tan Wan did not question this point in time, but kept it in mind silently and continued walking with Wang Mei.
There are about a dozen children living in the orphanage, all living in one room.
The bed was a large bunk bed for more than a dozen people, and the aisles were crowded, making it difficult to walk.
The quilt on the bed was rumpled, and Wang Mei explained that she hadn't had time to clean it after the children left.
Unlike the style of the front yard, most of the rooms in the backyard have no windows, or the windows are locked with locks.
There was no way to open the bedroom window. Tan Wan stood by the window and tried several times without success.
Seeing Tanwan like this, Wang Mei walked to the window and took out a key from her pocket.
It was a strange-shaped key. The lock head was a closed circle, and the barrel-shaped circle had a key tooth inside.
Wang Mei inserted the key into the lock cylinder of the window, turned it to the right, and the window opened with a click.
Although the windows can be opened, the opening size is limited, and can only go as far as possible.
"This is to prevent children from jumping out of the window." Wang Mei felt that she had used the wrong word, and added, "It is to prevent children from falling downstairs. This allows air circulation and prevents falls."
Tan Wan nodded, but faced the many doubtful points in Wang Mei's words, she didn't say anything.
After looking at the window, Wang Mei closed the window again, put away the keys and walked to the door to leave with Tan Wan.
Wang Mei stood by the door and waited, but saw that Tan Wan didn't show any sign of leaving.
There is a tall wooden trellis placed on the wall on one side of the room where the children live.
There are name cards on each shelf, one per person.
The strange thing is that even though the children have moved away, the personal belongings in the grid have not been completely taken away.
There are also many children who still have things left in their grids, such as crayons for drawing, toys and the like.
But this is wrong. If it is true as Wang Mei said, these children regard toys and crayons as treasures.
You should take these things with you when you leave, and you shouldn't leave them here...
The children were leaving in a hurry, Tanwan thought to himself.
His eyes swept across one of the boxes with 'Xiaoqi' written on it.
Xiaoqi is different from other children. Most of the other children will put some of their own treasured toys in the grid.
Or, some 'treasures' such as beautiful colored stones picked up from outside.
But Xiaoqi's grid is very clean, with only a diary and a pen inside.
Tan Wan thought that the children living here would record some daily life in the orphanage in their diaries, and perhaps write about the dark side of the orphanage.
Wang Mei glanced at the time and couldn't help but urge Tan Wan: "Officer Tan, you have to leave around the time."
"Ah, okay..." Tan Wan responded, quietly grabbing the diary and stuffing it into his coat pocket.
