“Don’t look at me,” Wang Huadong shook his head. “I just heard from my master that this kind of rapid manifestation may be caused by substances such as bleach. In fact, this is the first time I have encountered it.
However, I have used luminol in many scenes where blood was present, and this situation has never occurred.
I'm sure it's not blood."
"From a chemical point of view, Rubenol can glow because hemoglobin contains iron, which can catalyze the decomposition of hydrogen peroxide, turning hydrogen peroxide into water and single oxygen. Single oxygen is different from oxygen and can oxidize Rubenol again to make it glow.
Since you mentioned that bleach can make luminol glow quickly, it should be a hypochlorous acid type bleach, such as calcium hypochlorite, which can quickly reduce peroxide..." Bai Song followed Wang Huadong's thoughts and thought for a while: "Sodium hypochlorite, I remember its use as a disinfectant and pulp bleaching... In addition, it seems to be used to prepare ammonium chloride... Oh, no, this process is no longer used to prepare chloramine..."
"In other words, excluding the possibility of pulp bleaching, it must be used for disinfection?" After listening for a long time, Zhang Wei finally understood.
"It could also be a cover-up. After all, this thing can make luminol almost useless." Wang Huadong shrugged. "In fact, there are many things that can cause luminol to misjudge. Iron itself can do that. It seems... mustard also has this function."
"This is a troublesome situation. We can't just pry open the door and take a look." Bai Song asked, "Can we collect something to test it?"
"If there were only a few spots flashing blue light, I could collect some for testing to see if it was blood, but it's all over the ground..." Wang Huadong shook his head: "It's useless to call in a police dog in this situation. The smell of bleach is unpleasant for police dogs, too."
"Don't be discouraged. In fact, it is reasonable for people at the door to do the disinfection. Besides, Rubenno himself is just a supporting role. It's not like we can't handle the case without him." Bai Song thought for a while and said, "Go back to find Wang Liang and ask him to come over. The central control of this warehouse is connected to the lights outside. Dahei is a anchor and everything is done on the computer. And I see there is a camera facing the road. I guess he can occasionally broadcast live on the scene.
Ask Wang Liang if we can go in the opposite direction and take a look."
"This network intrusion is against the rules, right?" Wang Huadong touched his chin. "Last time in Southern Guizhou Province, we knew the other party was a criminal and the leader agreed. This time it's definitely not allowed."
"Really..." Bai Song was also a little anxious, and calmed down, "I'll find someone to check this big black first."
As he spoke, Bai Song called Wang Liang and asked him if he could retrieve Dahei's registration information from the platform.
"I can, but the problem is that I have to wait until tomorrow morning. They won't help me now." Wang Liang was also helpless: "Don't ask me to check their company's system. I don't have the technology to do that."
"Then tomorrow." Bai Song hung up the phone, feeling a little uneasy.
"Tomorrow is tomorrow, why are you in such a hurry?" Wang Huadong asked.
"It's better to be early than late." Bai Song gritted his teeth, "I have a friend who works on the live broadcast platform. She cheated me several times. I'll go find her."
As he said that, Bai Song called Zhou Xuan.
It was already past one in the morning, and it was a very inappropriate time to call, but since Zhou Xuan always cheated on him, he didn't feel uneasy.
"Hello? Bai Song? What are you doing so late?" Zhou Xuan quickly answered the phone.
"Is it convenient to ask you for help?" Bai Song asked directly.
"What help? You should find a time. I just got off the air..." Zhou Xuan's lazy voice came from the other end of the phone.
"Help me find the information of a YY anchor. I have the documents to retrieve evidence."
"You are a policeman, and you are coming to me for this?" Zhou Xuan was surprised.
"Help me. In Tianhua, two anchors from your platform died in the Xingang District." Bai Song said bluntly: "It's quite urgent."
"You are in charge of this case? Oh my god! Someone in our group was talking about this today! I saw you were not in Xingang District, so I didn't ask you." Zhou Xuan was very surprised: "Is he really dead?"
"Wait a minute, are you in a group? What group?" Bai Song asked.
"Ask me later and tell me the anchor's nickname. I'll check it for you first."
Bai Song turned around and asked Zhang Wei, then said to Zhou Xuan, "Brother Dahei."
"Okay, wait a moment... You don't need to send the paperwork. You can fill it in later if you need it..."
After more than ten seconds, Zhou Xuan said: "It's an internal group of the company. Last week, all the anchors of a company went offline within a day or two, especially one or two people in it who the platform still values.
Later, the platform contacted the boss of their company, but failed to get through. I heard that a streamer was reported missing in Beijing, and someone at the time was not afraid of making a big deal and said that it might be an accident. Today, someone contacted our customer service to retrieve the information, and the notice for retrieving evidence said it was a murder case. "
"Oh, that's what's going on." Bai Song nodded. This made sense.
"I'll send you the message later." Zhou Xuan said and hung up the phone.
…
"You have friends inside the platform?" Zhang Wei punched Bai Song, "Why don't you tell me?"
"Um... my classmate, after graduating from the police academy, became a live broadcaster. I originally thought she was just into this, broadcasting a bunch of random shit every day, and inexplicably becoming more and more popular. A while ago, I found out that her family is a shareholder of the live broadcast company." Bai Song spread his hands: "What's the point of telling you?"
"You don't understand. For live broadcast platforms, wild broadcasters like us, if we can get a better room number or a better recommendation, it is very valuable!" Zhang Wei said, "But I just said that. Now business is more important. When you are free in the future, remember to help me mention that my live broadcast room is called 'Wei Ge Talks about Cars'."
"Yeah, no problem." Bai Song kept it in mind.
After a while, Zhou Xuan sent Dahei's information and the information of the female anchor of their company. Bai Song directly forwarded it to Wang Liang, and soon, the resumes of these two people were completed.
Zhang Wei used to sell cigarettes and alcohol. Dahei, actually, was a salesperson at a pharmaceutical company.
Oh, you should call the salesperson.
Judging from his resume, he came from an ordinary family. After working as a salesman for a few years, he founded this company, engaged in car sales and live streaming, and it grew to this scale in just one or two years.
"These are still not enough," Bai Song was at his wit's end. "Let's talk about it tomorrow. Huadong, drive Zhang Wei back to rest first. He will leave tomorrow. I'll wait here. Come back later and be polite to the old man at the door."
"It's okay, we can go together," Zhang Wei shook his head, "It's dark here, I'm worried about you being alone, no matter how capable you are, you will also doze off and feel sleepy.
This matter is not negotiable."
