Detective from the future

Chapter 255 Suspected Object
Eight o'clock the next morning.

Han Bin and others rushed to the branch office.

Zheng Kaixuan also returned to the branch from Mu Xinran's house, while Tian Li and the technical team were still watching at Mu Xinran's house.

In order to save time, everyone gathered the case while having breakfast.

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

Zheng Kaixuan waved his hand, took a sip of soy milk, and then said slowly: "It was a calm night, and Tian Li and I took shifts to rest for a while."

"The suspect made a blackmail call at [-] o'clock the morning before yesterday. It has been two days and he hasn't contacted Mu Xinran again. This is not reasonable," Han Bin said.

"Could it be the reason for the large amount of extortion? It will definitely take time to raise 1000 million in cash." Li Hui guessed.

"I'm a little curious about how to deliver the 1000 million ransom." Zhao Ming said.

"If you want me to say, it's too fast to be a star, otherwise you won't be targeted." Sun Xiaopeng said.

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

"I went around when I came here. Lu Wen is busy in the laboratory, and the results are probably coming soon." Han Bin said.

"Mu Xinran's husband should be able to come today, and make a record for him." Zheng Kaixuan said.

"understood."

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

"As long as it has nothing to do with the case, no one will gossip about her nonsense." Han Bin laughed.

The criminal police team deals with criminal cases, and family disputes are not under their control.

There was an online dating homicide case. The husband of a person involved in the case asked Tian Li about the relationship between his wife and the suspect. In the end, Tian Li responded directly, wanting to know when he went home and asked his wife.

Tian Li's approach seems unreasonable, but it is the right choice.

Tian Li understands the case, even if she sympathizes with the husband in her heart, she can't reveal anything, this is discipline.

Criminal police are different from civilian police, they need to maintain sufficient majesty, so as to deter criminals.

The family of the police and civilians refers to the grassroots police, who serve the common people in the community, and serving the people is what they should be.

If the criminal police also learn this trick, ordinary people should feel insecure.

After dinner, Zheng Kaixuan went home and went to bed.

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

As soon as he walked to the door of the office, he ran into Lu Wen head-on.

Lu Wen had dark circles under his eyes and a stack of documents in his hand.

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

"That's right, I haven't even returned home yet, and I just squinted in the dormitory for more than three hours." Lu Wen yawned.

"Thank you." Han Bin said politely: "Xiaopeng, go get a cup of tea."

"No need, I'll give the test report to your team, go back and sleep for a while, don't drink tea to refresh yourself." Lu Wen said with a wry smile.

"Okay, that's enough, all the evidence has been checked."

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

Han Bin glanced at it, a material identification, a DNA identification, and a mobile phone.

Lu Wen followed the usual practice and gave a brief introduction: "The cigarette butt in the ashtray on the balcony matches Li Hanxuan's DNA, and 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 residues 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 can these two substances represent?" Li Hui asked doubtfully.

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

"I'm talking about glasses, can you hurry up and do it in one step." Li Hui rolled his eyes and said it as if he knew what aluminosilicate is.

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

Lu Wen was a little surprised, and gave a thumbs up: "Leader Han, you are professional enough."

"Team leader, what does the clay on the key mean?" Sun Xiaopeng didn't respond.

"The main ingredient of the key ink pad is clay." Han Bin responded and continued to analyze:
"There is no fingerprint 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 possibility is bigger. Someone used key ink pad to match the key."

"Mu Xinran's family has only been visited by three people recently. Apart from her, only Li Xia and Li Hanxuan are suspected." Li Hui said in a favorable manner.

"Tsk tsk, this is an important clue. Even if the person who distributed the key is not the main criminal, he is also an accessory." Zhao Ming laughed.

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

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

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

Lu Wen shook his head: "I don't know much about this. I can only try to find someone who is proficient in programming from the technical team. It's not certain whether I can track it down."

"In addition, the DNA of the cigarette butts found in the corridor has not been successfully compared, and the video has not been restored. I will inform you when there is news."

"Thank you." Han Bin said.

"Both serve the people." Lu Wen stood up and stretched his waist: "Okay, you guys investigate the case, I'll go back to sleep."

After watching Lu Wen leave, Han Bin thought for a moment: "Let's divide into two groups. Li Hui and I will go to Mu Xinran's house. One is to wait for the blackmailer's phone call, and the other is to make notes for Mu Xinran's husband."

"Zhao Ming and Xiaopeng, go to the place near Mu Xinran's house to look for keys and see if you can find any 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 woken up, eating in the living room in a thin pajamas, but her face had been put on makeup.

Han Bin didn't care, Mu Xinran's legs were more beautiful, but her overall figure was flat.

There are many beauties showing their thighs in summer. It's not that Han Bin has never seen them before, and he has long been familiar with them.

However, Li Hui was a little bit worse, he looked a little unnatural, his eyes were averted, and he didn't dare to take aim at Mu Xinran.

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

"The heating may have been turned on for the past two days, and the room is extremely dry." Mu Xinran responded, 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.

"Hey." Mu Xinran sighed: "Yesterday, that technician of yours took my mobile phone. I want to buy a new mobile phone. I'll be back soon."

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

"That phone is too old, I don't even know how to use it." Mu Xinran shrugged.

When mentioning the mobile phone, Han Bin took the opportunity to ask: "Where did you buy the previous mobile phone?"

Mu Xinran recalled: "I didn't buy it, it was a gift from someone else."

"Who sent it?"

"Ma Pengkun"
