"Come in."
"Creak …" The door creaked. Reuven walked in from outside and placed a document on the table.
"Captain Ma, Captain Zeng, the DNA test results for Ren Zhongyuan and the other victim are out. The similarity between the two is as high as 99.99%."
"It's finally confirmed. This means that our previous speculation was correct. I was really afraid that the DNA couldn't match." Ma Jingbo breathed a sigh of relief.
If the DNA couldn't match, it meant that there might be other victims.
Han Bin asked, "Reuven, has Zhao Xiaoshan's computer password been cracked?"
"It has been cracked. If you want to look for clues inside, you can send people to move it away at any time."
"Can you recover the surveillance video we sent yesterday?"
Reuven spread his hands. "It's still being processed. I can't say for sure now."
"Thank you."
"It's my job. I'll inform you as soon as there's any news." With that, Reuven left the office.
The work of the technical team was no easier than that of the criminal investigation team. He was not in the mood to gossip.
Ma Jingbo sighed. "We can basically confirm that this is a serial murder case. Currently, the fate of the last victim, Zhao Xiaoshan, is unknown. Comrades, time is of the essence."
"Captain Ma, I want to give a statement to the parents of the second victim, Cao Da," Han Bin suggested.
Ma Jingbo frowned. "Cao Da's parents are still in quarantine. It's not convenient for them to contact the outside world for now."
"You can do it in another way."
"What way?"
"Video call."
Ma Jingbo smiled. "You know how to play when the time comes. Alright, it's a special time. Be more flexible."
"Tian Li, did the communications company send over more detailed call records?"
"Not yet."
"Remember to urge them." After Ma Jingbo finished speaking, he glanced at everyone.
"That's the arrangement for now. Everyone split up. If there's any problem, you can talk to me alone."
"Yes."
…
At 10: 30 in the morning, Han Bin contacted Cao Da's mother and invited them to video call her.
This was the first time Han Bin was giving a statement through video call.
After the video call was connected, the person on the other side was a woman in her sixties. Her hair was already a little white.
"Cough …" Han Bin coughed lightly. "Can you hear me?"
"Sure."
Han Bin went straight to the point. "My surname is Han, and I'm from the Criminal Investigation Team of Yuhua Branch. What's your relationship with Cao Da?"
"I'm Cao Qin, Cao Da's mother."
Han Bin continued to ask, "How many people are there in your family?"
"Four. Cao Da has an older brother and an older sister."
"Where is Cao Da's father?"
Cao Qin snorted, "He's dead."
"When did he die?" Han Bin asked.
Cao Qin pouted. "How would I know?"
"Pa!" Slamming the table, Zhao Ming reprimanded, "Be serious. We're taking your statement now, understand?"
Cao Qin lowered her head and said, "We're divorced."
Han Bin asked, "Cao Da has been following you?"
"Yes, if he had followed that damn father of his, he probably wouldn't have grown up."
"When did Cao Da go missing?"
Cao Qin recalled. "I think it was on the 17th of January."
Han Bin frowned. "What do you mean by 'I think'?"
"I'm old, and I can't remember."
Han Bin knocked on the table. "Why did the police station's file say that he went missing on the 18th of January?"
"Aiyo, it's been almost a month. I really can't remember."
"Bang!" Zhao Ming could not help but slam the table again. "What's with your attitude? Do you know the situation now? Your son is dead, and you're still trying to fool us?"
"How am I fooling around? My son is dead. How can I not be worried? How can a little cop like you say that?" Cao Qin glared at him and said loudly, "Moreover, isn't it the police's job to catch the murderer? Can't you investigate it yourself? "
"You're really something." Zhao Ming snorted and thought to himself, 'This is the first time I've seen a mother like this.'
Cao Qin asked back, "Officer, have you found my son's murderer?"
"We're investigating. I hope you can cooperate with us so that we can catch your son's murderer as soon as possible," Han Bin said seriously.
"I'm cooperating. Once you contacted me, I immediately video-called you, right?"
Han Bin could not be bothered to argue with her and continued to ask, "When did you report the case?"
"I think it was on the 23rd of January."
"Your son went missing on the 18th. Why did you only call the police on the 23rd?"
"He's already an adult. I can't do anything about it. How could I have known that something would happen to him?" Cao Qin sighed. "I was still hoping that he would take care of me when I was old."
"Where does Cao Da live?"
"At my house."
"He lives with you?"
"Yes."
"When was the last time you saw him?"
"I think …" Cao Qin carefully recalled. "On the morning of the 18th. He left without eating breakfast and hasn't been back since."
"You're quite open-minded. You lived in the same house and only called the police after five days," Han Bin said.
"Officer, I know what you're thinking. You think that I'm not a good mother." Cao Qin sighed again.
"Cao Da, it's not that I don't want to take care of him. He's just a young man in his twenties. How can I take care of him? He doesn't come home every few days. I'm already used to it. "
"What did Cao Da do for a living?"
"Everything?"
"What did he do before he died?"
"He probably didn't have a job at that time."
Han Bin changed the way he asked, "What was the last job he had?"
"I can't remember. He was a person who didn't grow up. He had high standards and always wanted to do something big. In the end, he couldn't do anything. He didn't work for more than two months. I couldn't be bothered to ask. He wouldn't work for long anyway."
"From your tone, it sounds like you're very disappointed in him."
Cao Qin's expression was complicated. "I don't have much ability myself. I don't even know how to live. What right do I have to ask others?"
"It wasn't easy for you to raise three children," Han Bin comforted her.
Cao Qin lowered her head and rubbed her eyes. "What's the point of saying all this? Let's talk about the case."
"Did Cao Da offend anyone recently?"
"He doesn't do his job all day long. He hangs around with a bunch of scoundrels and offends a lot of people. I can't do anything about it, so I won't ask. "
"Has Cao Da looked for a job recently?"
"Yes."
"Did he tell you about it?"
"He doesn't need to tell me. I know. He's either thinking about resigning or on the way to looking for a job. He's like that. He's always biting off more than he can chew. He always thinks that he's special and that he'll get lucky one day. "
"I want to see Cao Da's personal belongings. For example, his computer, documents, or employment forms."
Cao Qin shook her head. "No, he threw all his things away."
Han Bin was speechless.
