Chapter 432

"Come in."

"Creak..." As soon as the door rang, Lu Wen came in from the outside and put a document on the table,

"the DNA identification results of Captain Ma and captain Zeng, who had a heavy responsibility, and another dead person came out, and the DNA similarity of the two people was as high as 99.99%."

"It's finally confirmed, which shows that the previous conjecture is correct. I'm really afraid that the DNA can't be compared." Ma Jingbo breathed a sigh of relief.

If the DNA doesn't match, there may be other victims.

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

"It's cracked. You need to check the clues inside. You can send someone to move away at any time."

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

Lu Wen stood up and said, "it's still being dealt with. I can't say it right now."

"Hard work."

"Yes, I'll let you know as soon as I get the news." With that, Reuven left the office.

The work of the technical team is no easier than that of the criminal investigation team. He has no mind to gossip here.

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

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

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

"You can take notes in another way."

"How?"

"Video call."

Ma Jingbo laughed, "you boy will play then, OK, special period, be flexible."

"Tian Li, did the communication company send more detailed call records?"

"Not yet."

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

"let's arrange this first. Let's act separately. If you have any problems, you can tell me alone."

"Yes."

……

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

It's the first time that Han Bin has taken notes through video.

After the video was connected, there was a 60 year old woman with gray hair.

"Cough..." Han Bin coughed softly: "can you hear me?"

"Yes."

Han Bin opened the door and said, "my name is Han. I'm from the criminal investigation team of Yuhua Branch. What's the relationship between you and Cao Da?"

"My name is Cao Qin. I'm Cao Da's mother."

With the mother surname is not common, Han Bin continued to ask, "how many people in your family?"

"Four, Cao DA and a brother and a sister."

"Where's Cao Da's father?"

Cao Qin snorted, "dead."

"When did you die?" Han Bin asked.

Cao Qin said, "I don't know."

"Pa!" As soon as Zhao Ming patted the table, he scolded, "be serious. I'm taking notes for you now. Do you know?"

Cao Qin bowed his head and said, "we are divorced."

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

"Yes, if you follow his dead father, you may not grow up with Ben."

"When did Cao Da disappear?"

Cao Qin recalled, "it seems to be January 17."

Han Bin frowned, "what is like?"

"I'm too old to remember."

Han Bin knocked on the table, "on the file of the police station, why is the missing time written on January 18?"

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

"Bang!" Zhao Ming can't help patting the table again, "what's your attitude? Do you know what's going on now? Your son is dead, and you're still fooling around here."

"How can I make a fool of myself? My son is dead. I can't worry. How can you talk to this little policeman?" Cao Qin glared at Zhu Zi and said in a loud voice, "besides, isn't it your police's business to catch the murderer? You're not going to check it yourself? "

"That's great." Zhao Ming snorted and whispered. It's the first time I've ever seen a mother like this.

Cao Qin asked in turn, "Comrade police, have you found the murderer who killed my son?"

"We are investigating. I hope you can cooperate with us so that we can catch your son's killer as soon as possible." Han Bin is right.

"I'm cooperating. As soon as you get in touch, I'll make a video, right?"

Han Bin is too lazy to argue with her. He continues to ask, "when did you report the case?"

"It's like January 23."

"Your son disappeared on the 18th. Why did you call the police on the 23rd?""I don't care about such a big man as him. How could I have thought that something would happen to him?" Speaking of this, Cao Qin sighed, "I still expect him to provide for me."

"Where does Cao Da live?"

"In my house."

"To live with you?"

"Yes."

"When was the last time you saw him?"

"It's like..." Cao Qin carefully recalled, "on the morning of the 18th, he left without breakfast and never came back."

"Your heart is big enough. You live in the same house. It took you five days to call the police." Han Bin said.

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

"Cao Da, I don't want to control him. He is a young man in his twenties. Can I control him? He doesn't go home every so often. I've been used to it for a long time

"What does Cao Da do?"

"Did you do everything?"

"What did he do before he died?"

"He shouldn't have been working then."

Han Bin changed a way to ask, "what was the last job he did?"

"I can't remember clearly. He's just a person with no long life. He has a high vision and always wants to do something big. As a result, he can't do anything. No job can last more than two months. I don't bother to ask. Anyway, he can't do it long."

"You sound disappointed with him."

Cao Qin looked complicated and said, "I don't have any skills myself. I don't understand myself. I'm qualified to ask others."

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

Cao Qin lowered his head and wiped his eyes. "What's the point of saying these? Let's talk about the case."

"Has Cao Da recently committed any crimes against anyone?"

"He's not doing his job all day long. He's fooling around with a group of friends, and he's doing a lot of things to offend people. If I can't manage it, I won't ask. "

"Cao Da, have you been looking for a job recently?"

"Yes."

"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 such a disposition. He always thinks that he is extraordinary and will be lucky one day. "

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

Cao Qin shook his head, "no, his things are thrown away."

Han Bin "..."
