In the bathroom, Bao Sheng used a flashlight to shine through the shower curtain. Under the flashlight light, there were two tiny holes in the corners of the shower curtain.
"Hydrochloric acid?" Duan Mo asked.
"I'm not sure if it's hydrochloric acid, but it's definitely corrosive." Lu Wuchuan stood up and asked Bai Qisheng, "Did you touch anything in the house when you came yesterday?"
"I...I opened the closet in the bedroom, and the suitcase that Xiuxiu took when she went out was not there. The things inside were the same as before she left, so I closed it again." Bai Qisheng said nervously, "I also removed the suitcase from the refrigerator.
I took a bottle of water and sat in the study for a while, but nothing else was touched."
"From now on, don't touch anywhere." Bao Sheng warned and started to remove the shower curtain.
He is tall and can reach the shower curtain rod with just a raised hand without even stepping on a stool.
The removed shower curtain was put into the evidence bag, and he began to look for other traces.
The bathroom is not too big. The shower room is separated by a shower curtain. There is a cabinet-type sink and a toilet outside. Two towels, one orange and one blue, are hung neatly on the towel bar on the wall.
On the shelf in front of the mirror on the wall above the sink is a pair of toothbrushes, couple's size, with a razor and a bottle of aftershave next to them.
Lu Wuchuan opened the cabinet under the sink. There were two barrels of laundry detergent, a bottle of bath soap, and a bottle of shampoo, all of which were unopened. In the drawer next to it were some toiletries and soaps, which were also brand new.
. It can be seen that Cui Xiu is a very orderly person, and everything at home is prepared in advance.
"Lijun, this shower head has been damaged." Bao Sheng held the shower head taken from the wall with two fingers. "There are traces of wiping on it, and there is also a fingerprint left by a rubber glove."
Although there were no fingerprints, he still removed the nozzle and put it into the evidence bag.
Next, every corner of the bathroom was inspected one by one. A very small amount of blood stains left after being washed with water were found under the sink cabinet. The same situation was found in the corner of the toilet near the wall.
On the kitchen counter, near the sink, there is a pair of couple's water cups. Bai Qisheng said those were his and Cui Xiu's cups.
Duanmo carefully sprinkled iron powder particles on the handle of the pink cup and scanned it repeatedly with a magnet, but no fingerprints were found.
There were fingerprints on the other blue cup. After preliminary comparison, it was Bai Qisheng's.
"After a cup is used, even if it is cleaned carefully, there will still be fingerprints on the cup handle, and no one will wipe it off intentionally." Lu Wuchuan put both cups into evidence bags.
I opened the kitchen cabinet again and took a closer look. The dishes and glasses were all neatly placed. However, there were only three wide-mouth glasses.
"How many cups does this have?" he asked Bai Qisheng.
"Four."
"Are you sure it hasn't been broken?"
"At least not in the past few days." Bai Qisheng looked very complicated, "Did the murderer take it away?"
The actions of these policemen made him more and more convinced that Cui Xiu had been murdered. His heart was as sharp as a knife, but he was helpless.
"If it's not placed elsewhere, it's possible." Duanmo said, and sprinkled the iron powder on the faucet of the sink.
Bao Sheng inspected it more carefully, not even an inch of the ground was missed.
It wasn't until I checked at the gate that I finally found a little trace on the outside of the threshold.
"The traces of the suitcase's pulley have been cleaned in the house, but here... it may have been neglected." He lay at the door and carefully rubbed the traces.
Bai Qisheng squatted in the corner of the door, with a depressed look on his face, and his eye circles turned red unconsciously. He took off his glasses and wiped his eyes with his sleeves, but the tears seemed to flow down again as if he couldn't stop them.
"You are a grown man after all, don't cry all the time." Bao Sheng got up from the ground, took off his gloves, took out a pack of tissues from his pocket and put it into his hand, "Here, wipe it quickly and make room.
"
Bai Qisheng originally thought he was going to comfort himself, but when he heard the last part of the sentence, he stood up angrily, simply stepped out from the threshold and sat on the stairs.
The door of the neighbor opposite opened with a creak, and the face of a wrinkled old lady poked out, asking warily: "What are you doing?"
Even though the old lady is quite old, her voice is not quiet at all.
Bao Sheng casually took out his ID from his coat pocket and said, "Auntie, we are the police. Has anyone come back from this house in the past few days?"
The old lady put on her reading glasses, looked at his ID, and pointed at Bai Qisheng sitting on the stairs: "Isn't he from this family? You can see him every now and then."
"Has anyone been here in the past two or three days?" Duanmo crossed the threshold and went to the opposite door.
"That girl went out a few days ago, and I saw her leaving with a small box." The old lady opened the door completely, "What happened? Isn't their family a pyramid scheme?"
"Auntie, you are overthinking." Duanmo smiled slightly, "We just wanted to find the owner of this family to ask about their work, but we couldn't find anyone."
The old lady nodded assuredly: "Oh, that's good. Don't be a pyramid scheme, it's too deceptive."
"Auntie, just now you said you saw her carrying the box and leaving. What happened after that? Did you see her come back?" Duan Mo asked.
"That's not what I was looking at." The old lady took off her reading glasses and held them in her hand. "But one night, someone was talking at the door. I listened to the sound and looked through the peephole. I came out late, so I looked at the door opposite.
Close."
Duanmo quickly asked: "When?"
"Let me think about it." The old lady pointed her finger on her forehead, "It seems to be the day before yesterday... No, it could be the day before yesterday, or the day before yesterday. This person is old and his memory is not good. Anyway, it happened in those two days.
Son."
It's normal for the elderly to not remember. Duanmo continued to ask: "Then do you still remember what time it was?"
"Oh, it must be nine o'clock." The old lady recalled carefully, "The TV series has already finished its second episode."
"Did anyone come out after the door closed?" Duanmo asked again.
"Then I don't know. I watch TV every day and go to bed at about ten o'clock." The old lady waved her hand, "I can't hear someone going out."
"Auntie, who else is there in your family?" Duanmo thought. The old lady looked to be in her seventies at least. It was normal for her to not listen to anything when she fell asleep. If there was someone younger in her family, maybe
You can hear the movement on the other side.
It's a pity that the old lady shook her head and said: "My children have long wanted to take me over, but I thought, they are busy with work and have to worry about their children, so how can they have the energy to take care of me, an old woman. Besides, I have lived here for dozens of years."
I've long been used to it, and it's not fun to change places. So, I've been living here by myself."
Not getting the expected answer, I couldn't help but feel a little disappointed. Duanmo asked the old lady a few more questions. Apart from hearing the sound of someone talking, the old lady only saw the moment the door closed and couldn't provide anything else.
