Chen Shi returned home, called Tao Yueyue to the living room, turned on the computer, plugged in the USB flash drive, and ran a piece of software.
He said, "Come on, let's draw a portrait of that prisoner."
Tao Yueyue said: "Isn't this the software used to fight faces in the Public Security Bureau? Where did you get it?"
"Borrowed."
"borrow?"
"The person was not in front of the computer when I borrowed, so don't care about these details. I will delete it after I finish it."
The two used the nose, eyes, and ears in the software to piece together for a long time. Tao Yueyue kept frowning. It took an hour to finally put together a face. Chen Shi asked, "Is he the same as Zhou Xiao?"
"Uh, it doesn't feel like... Uncle Chen, I can't remember."
"All right!" Chen Shi sighed and deleted the software.
"But see you again, I probably can recognize it."
The next day, Lin Dongxue came to the police station responsible for the disappearance of Jiang Hui and Jiang Ming. Because they had been abducting recently, the two missing underage police stations paid more attention. They went to many places in the past few days.
The gain is still a little bit. The surveillance of a certain hotel captured a figure wearing an experimental school uniform on the second day after the two children disappeared.
The figure flashed across the alley.
The camera was originally directed at the corridor, and took a picture of the alley through the glass. The picture was not very clear. The police showed it to Lin Dongxue. Lin Dongxue said, "This school uniform is for female students."
"From the side of the reference, the height and body shape are also a bit close to Jiang Hui." The policeman said.
"Have you been there?"
"This segment of surveillance is a reward we posted on the Internet for providing clues. We only received it last night. It is ready to pass now. Will Police Officer Lin be with us?"
"Okay, let's go together!"
Lin Dongxue came to the scene in a police car. The roadway was narrow, with a road on one side and a hotel on the other. The police found a button here, suspected to be on a school uniform.
In addition, a dead cat was found, a variegated little female cat, with very cloudy eyes.
When looking for the screenshot of the surveillance video on the mobile phone, they finally stopped in front of a door. Lin Dongxue pushed in and found that it was a safe passage for a home appliance mall. She went in and checked, and the police went to the person in charge.
According to the person in charge, the door is locked when the mall closes at six every night.
The policeman asked: "At eight o'clock in the evening on April 2, are you sure you locked the door?"
"It must be locked."
At this time, Lin Dongxue came out from the door and said, "I just asked the employees. They said that although the mall closes at six o'clock, as long as there are customers, the employees have to work overtime, sometimes at eight or nine o'clock in the evening."
"Who said that!?" The person in charge was a little nervous.
"Don't worry, we are not from the Labor Bureau. We are the police. A child came in on the night of April 2. Do you have surveillance?"
"The surveillance is in the mall."
Immediately, the police checked the surveillance and found the scene of two children walking in at 6 pm on April 2nd. It was undoubtedly Jiang Hui and Jiang Ming. Lin Dongxue asked the clerk who was still working at the time. They said that they did not. Impression, I see too many guests every day.
Lin Dongxue secretly wondered, why two came in and one went out? Could it be...
Lin Dongxue enters the safe passage from the inside of the mall. There are four safety exits on each floor. The safe passage loops around the outside of the mall. There is an exit on each side of the alley. There are stairs in the passage to go up and down.
It is daytime, there are no people in the safe passage, only a cleaner sweeping the floor.
She pulled up the safety exit and found that it needed a key to lock it, so she asked the person in charge whether the keys for all safety exits were the same? Who has the key in hand
The person in charge said: "Each door can be opened with a key. There are three in total. One is here and the other is a spare. They are kept in the security room. The other is used by employees in turn. Whose turn is to lock the door after get off work."
"Who locked the door that day?"
"I'll find it for you."
Finding the employee, he said that the door was locked at seven that night, and Lin Dongxue asked, "Have you checked the inside?"
"There is nothing to check, except for cleaning supplies, there is nothing to lose."
"How is the door outside on the first floor locked?"
"It's locked from the outside!"
Lin Dongxue recorded his name and ID number, and took another photo of him to check back. If he locked the door at seven that night, the surveillance of the nearby hotel would take it.
By the way, she took a picture of the lock and the key, and sent them to Lin Qiupu, asking: "Is this kind of lock easy to open?"
Lin Qiupu replied: "It's easy to open, anyone who knows a little how to open a lock can open it."
She also called for the cleaner who cleaned here on the morning of April 3. The cleaner said: "I didn't notice anything, but there was a dead cat on the top stairs. I threw it out."
"What else is there besides the dead cat?"
"Oh, there are a few more flowers, wrapped in plastic paper... I wonder who is this, do you leave this for funerals for the cat?"
"wait a moment."
Lin Dongxue took her to the alley and asked if it was this dead cat. The cleaner repeatedly said: "Yes, it's just this dead cat... Why are you looking for this?"
"It's not convenient to disclose for the time being. Is it convenient to leave a contact information?"
She bagged the dead cat, said goodbye to the police, and returned to the bureau.
Peng Sijue tested it, and the results came out after a while. He said: "This cat was injected with dimethyl sulfoxide and was poisoned to death."
"Jiang Hui stole dimethyl sulfoxide from the school. She didn't intend to kill her brother. Judging from the bouquet placed on the scene, she probably euthanized the cat."
"I don't know much about veterinarians. You can find a pet hospital to find out if this cat has a disease."
"I don't need to investigate this, the missing child is the focus." The investigation of the case does not have to be exhaustive. You must make choices and focus on the blade. This is what Lin Dongxue learned from Chen Shi.
"Where did the cat come from?"
"In the safe passage of a shopping mall, the missing child has been there. I didn’t feel very good when I went in. It was empty and quiet, and there was no surveillance. Except for employees who occasionally came in to smoke a cigarette, almost no one came in. Locked the door, the mall is so noisy, you can't hear anything outside."
"In this case, I will send a few people to you to take a sample on the spot."
"Thank you, Captain Peng!"
In the afternoon, Lin Dongxue brought a few technical policemen to collect evidence. One person was in charge of one floor. Lin Dongxue walked around anxiously on the first floor. She was very conflicted. She hoped that the case would progress, but was also afraid of turning into a criminal case.
The phone rang, and a policeman said, "Blood stains were found on the third floor!"
Everyone rushed over, sprayed luminol reagent on the ground, and the blood stains were unobstructed under the ultraviolet light, and there were clear traces of wiping.
Lin Dongxue felt a little dizzy and said, "Collect the evidence and take it back for testing!"
