Detective from The Future

At eight o'clock in the morning the next day.

Han Bin and others rushed to the branch office.

Zheng Kaixuan also returned to the branch from Mu Xinran's home, Tian Li and the people from the technical team were still staring at Mu Xinran's home.

In order to save time, everyone had breakfast while summarizing the case.

Han Bin handed Zheng Kaixuan a cup of hot soy milk and asked, "Team Zheng, was there anything like that last night?"

Zheng Kaixuan waved his hand, first took a sip of soy milk, and then slowly said: "It was calm all night, and Tian Li and I had a shift for a break."

"The suspect was a blackmail call at 10 o'clock in the morning the day before yesterday. It has been two days since I haven't contacted Mu Xinran. This is not in line with common sense." Han Bin said.

"Could it be the reason for the large amount of extortion? It will definitely take time to raise 10 million in cash." Li Hui guessed.

"I'm a bit curious, how to pay the ten million ransom." Zhao Ming said.

"If you want me to say, it's better to be a celebrity to make money too quickly, or else I won't be targeted." Sun Xiaopeng said.

Zheng Kaixuan ate half a fried dough stick, padd his stomach, and asked, "Is there any news from the technical team?"

"When I came, I went around, Ruben was busy in the laboratory, and it is estimated that the results will soon come out." Han Bin said.

"Mu Xinran's husband should be here today and give him a note." Zheng Kaixuan said.

"understood."

"When I left today, Mu Xinran begged me not to tell her husband about her and Li Hanxuan." Zheng Kaixuan smiled.

"As long as it has nothing to do with the case, no one will chew on her little mess." Han Bin smiled.

The criminal police team handles criminal cases, and family disputes are not in their control.

There was an online dating murder case. The husband of a person involved asked Tian Li about the relationship between his wife and the suspect, but he was directly attacked by Tian Li and wanted to know when he went home to ask his wife.

Tian Li's approach may seem unhuman, but it is the right choice.

Tian Li understands the case, even if he sympathizes with the husband in his heart, he can't reveal anything. This is discipline.

The criminal police are different from the civilian police. They need to maintain sufficient authority to deter criminals.

The police and the people's family refer to the grassroots police, who serve the people in the community, and it is necessary to serve the people.

If the criminal police learned this, the people would feel insecure.

After the meal, Zheng Kaixuan went home to sleep.

Han Bin packed his equipment and prepared to take someone to Mu Xinran's house to replace Tian Li.

As soon as I walked to the door of the office, I ran into Ruben head-on.

Ruben wore a black eye with a stack of papers in his hand.

Han Bin returned to the office, asked Lu Wen to sit in a chair and asked, "I stayed up late last night."

"Yes, I haven't even returned home until now, so I squinted in the dormitory for more than three hours." Ruben yawned.

"Thanks." Han Bin said politely: "Xiaopeng, go and pour a cup of tea."

"No, I will give the test report to your team, go back to sleep for a while, don't refresh yourself after drinking tea." Ruben smiled bitterly.

"Yes, that saves it. All the evidences have been checked."

"For the time being, only three copies have come out." Lu Wen said, handing the report to Han Bin.

Han Bin glanced at it, one for material identification, one for DNA identification, and one for mobile phones.

According to the usual practice, Lu Wen gave a brief introduction: "The cigarette butts in the balcony ashtray match Li Hanxuan's DNA. It is indeed his cigarette."

"Only Mu Xinran's fingerprints were found on the plastic box of the equipment key, and no one's fingerprints were found on the three spare keys. However, I did a detailed inspection and found the residue of SIO2 and Al2O3 on the green handle key. , But the content is so small that it is difficult to detect with the naked eye." Lu Wen said.

"What do these two substances represent?" Li Hui wondered.

"The main components of aluminosilicate are SIO2 and Al2O3." Lu Wen explained.

"I said glasses, can you please hurry up and do it in one step." Li Hui rolled his eyes, saying as if he knew what aluminosilicate was.

"Aluminosilicate minerals will form clay after weathering on the earth's surface." Han Bin continued.

Lu Wen was a little surprised, with a thumbs up: "Leader Han, professional enough."

"Group leader, what does the clay on the key mean?" Sun Xiaopeng did not react.

"The main component of the key ink pad is clay." Han Bin responded and continued to analyze:

"There are no fingerprints on the key, which usually means that no one has touched the key, or touched it with gloves; and clay was found on the key. I think the second one may be larger. Someone uses key ink to match the key."

"Mu Xinran's house has only been to three people recently. Excluding her, only Li Xia and Li Hanxuan are suspected." Li Hui said.

"Tsk tusk, this is a major clue, even if the person with the key is not the main culprit, he is also an accessory." Zhao Ming smiled.

Lu Wen interrupted the discussion and continued: "There is another situation. When I tried to restore the video, I found that there was a hidden software in Mu Xinran's phone that could eavesdrop on incoming phone calls."

"Who did Mu Xinran offend? Even the phone was tapped." Li Hui said.

"Can you find the IP of the monitoring phone through this software?" Han Bin asked.

Ruben shook his head: "I don't know much about this. I can only try to find someone who is proficient in programming in the technical team.

"In addition, the cigarette **** DNA found in the corridor has not been successfully compared, and the video has not been restored. When I have news, I will inform you to live."

"Thanks." Han Bin said.

"Each and each other are serving the people." Ruben stood up and stretched his waist: "Yes, you can investigate the case. I'll go to sleep."

After watching Lu Wen leave, Han Bin thought for a moment: "We were divided into two groups. Li Hui and I went to Mu Xinran's house. One was to wait for the blackmailer's call, and the other was to make a transcript for Mu Xinran's husband."

"Zhao Ming and Xiaopeng, go to the place near Mu Xinran's house with the keys to see if you can find clues."

"Yes."

...

Half an hour later, Han Bin and Li Hui arrived at Mu Xinran's house.

Li Xia is busy in the kitchen.

Mu Xinran seemed to have just gotten up, eating in the living room in a thin pajamas, but with makeup on her face.

Han Bin didn't care, Mu Xinran had pretty legs, but the overall figure was flat.

There are so many beauties with thighs exposed in the summer, and Han Bin hasn't seen him before.

However, Li Hui was a little worse, he was a little unnatural, his gaze was a little evasive, and he dared not aim at Mu Xinran.

Han Bin looked at Mu Xinran and joked: "Miss Mu, you dress so casually, you really don't treat us as outsiders."

"The heating may have been on these two days, and the room is so dry and panic." Mu Xinran replied and continued: "Officer Han, can I go out today?"

"What's the matter?" The blackmailer might call at any time, Mu Xinran went out, and Han Bin had to follow it.

"Hey." Mu Xinran sighed, "Yesterday, your technician accepted my mobile phone. I want to buy a new mobile phone and I will be back soon."

"Didn't he give you a spare cell phone." Han Bin said.

"The style of that phone is too old, I can't use it." Mu Xinran shrugged.

Speaking of mobile phones, Han Bin asked, "Where did you buy your previous mobile phone?"

Mu Xinran recalled: "It was not bought, it was given by someone else."

"Who gave it?"

"Ma Pengkun"
