Detective from The Future

"Come in."

"Crack..." With a sound of the door, Ruben walked in from outside and put a document on the table.

"The DNA identification results of Captain Ma, Captain Zeng, Ren Chongyuan, and the other deceased person have come out. The DNA similarity between the two people is as high as 99.99%."

"It's finally confirmed. This shows that the previous speculation is correct. I am really afraid that the DNA will not match." Ma Jingbo breathed a sigh of relief.

If the DNA does not match, then there may be other victims.

Han Bin asked, "Lu Wen, has Zhao Xiaoshan's computer password been cracked?"

"It has been cracked. You have to check the clues inside, and you can send someone to remove it at any time."

"Can the surveillance video we sent yesterday be restored?"

Lu Wen spread his hands, "It's still being processed, I can't say it now."

"Thank you."

"Yes, I will notify you as soon as I have news." After speaking, Ruben left the office.

The job of the technical team is not easier than that of the criminal investigation team, and he has no intention of gossiping here.

Ma Jingbo sighed, "It is basically certain that this is a serial homicide. At present, the life and death of the last victim, Zhao Xiaoshan, is uncertain. Comrades, time is very tight."

"Captain Ma, I want to make a note for the parents of the second victim, Cao Da." Han Bin suggested.

Ma Jingbo frowned, "Cao Da's parents are still in isolation and it is temporarily inconvenient to contact the outside world."

"You can take notes in another way."

"In what way?"

"video call."

Ma Jingbo smiled, "You kid will play when the time comes. Okay, during special times, be flexible."

"Tian Li, did the communications company send more detailed call records over there?"

"not yet."

"Remember to hurry up." Ma Jingbo finished speaking and glanced at the crowd.

"Then make arrangements like this first, let's move separately. If you have any questions, you can tell me individually."

"Yes."

...

At 10:30 in the morning, Han Bin contacted Cao Da's mother and invited them to make a video call.

It was the first time Han Bin made a transcript via video.

After the video was connected, the opposite was a woman in her sixties, her hair was a bit gray.

"Cough..." Han Bin coughed slightly, "Can you hear it?"

"can."

Han Bin said straightforwardly, "My name is Han, and I belong to the Criminal Investigation Team of Yuhua Branch. What is your relationship with Cao Da?"

"My name is Cao Qin, Cao Da's mother."

It is not common to have a mother's surname, Han Bin continued to ask, "How many people are there in your family?"

"Four, Cao Da also has a brother and a sister."

"Where is Cao Da's father?"

Cao Qin snorted, "Dead."

"When did you die?" Han Bin asked.

Cao Qin curled her lips, "I don't know."

"Pop!" Zhao Ming slapped the table and scolded: "Be serious. I'm making a transcript for you now, don't you know?"

Cao Qin lowered her head and said, "We two are divorced."

Han Bin asked, "Cao Da has been following you?"

"Yes, if you follow his dead ghost father, you might not grow up with him."

"When did Cao Da disappear?"

Cao Qin recalled, "It seems to be January 17th."

Han Bin frowned, "What do you mean like?"

"I am too old and can't remember."

Han Bin knocked on the table, "Why is the missing date written on the police station's file on January 18th?"

"Hey, it's been almost a month, I really can't remember."

"Bang!" Zhao Ming couldn't help but patted the table. "What is your attitude? Do you know what's going on now? Your son is dead, and you are still fooling around here."

"How am I messing up? My son is dead. Why don't I worry, how do you say the policeman." Cao Qin stared at her eyes and made a loud voice. "Besides, is it not your police's business to catch the murderer?" You won't check it yourself?"

"Really good." Zhao Ming snorted and secretly said, this is the first time I've seen someone like this.

Cao Qin asked in turn, "Comrade police, has the murderer of my son been found?"

"We are investigating and hope that you can cooperate with our work so that we can catch the murderer of your son as soon as possible." Han Bin said sternly.

"Isn't I cooperating? As soon as you contact, I will quickly video, right?"

Han Bin was too lazy to talk to her, and continued to ask, "When did you report the case?"

"It seems to be January 23rd."

"Your son disappeared on the 18th, why did you call the police on the 23rd?"

"He's such a big man, I can't control it. How could I have thought that something will happen to him." When it came to this, Cao Qin sighed, "I, I still count on him to support me in retirement."

"Where does Cao Da live?"

"at my house."

"Live with you?"

"Yes."

"When was the last time you saw him?"

"It seems to be..." Cao Qin carefully recalled, "On the morning of the 18th, he left without breakfast, and never came back."

"You have a big heart. You live in the same house and call the police after five days." Han Bin said.

"Comrade police, I know what you are thinking, and I think my mother is incompetent." Cao Qin sighed again.

"Cao Da, it's not that I don't want to control him, he is a young man in his twenties, can I manage it? He doesn't go home every other time, I've long been used to it."

"What does Cao Da do?"

"Have you done everything?"

"What did he do before he died?"

"He should have been out of work at that time."

Han Bin changed his question, "What was the last job he did?"

"I can't remember, he is a man with no long-term nature, he has a high vision, always thinking about doing a big business, but what he can't do in the end, no one can work for more than two months, and I don't bother to ask. It won’t last long anyway."

"Listening to your tone, I seem to be disappointed in him."

Cao Qin looked complicated and said, "I don't have any abilities myself, and I don't really understand how I am qualified to ask others."

"It's not easy for you to raise three children." Han Bin said relievedly.

Cao Qin lowered her head and wiped her eyes, "What's the meaning of this, let's talk about the case."

"Did Cao Da sin against anyone lately?"

"He doesn't do his job properly all day, he messes with a group of friends, and he does things that offend people. I can't manage it, so I don't ask."

"Cao Da, have you looked for a job recently?"

"Have."

"He told you?"

"Don't tell me, I know. He is either thinking about resigning, or on the way to find a job. He has this temperament. He is so lofty and always feels that he is special. He can hit the big luck one day."

"I want to take a look at Cao Da's personal belongings, such as computers, documents, and recruitment."

Cao Qin shook her head, "No, he threw away all his things."

Han Bin "..."
