Chapter 765: Interrogation of Zheng A-Mei

Now that the hotel cleaner Zheng Amei's suspicion was confirmed, Huang Mao quickly led people to the hotel where the crime occurred. In about an hour, he summoned the other party back to the brigade.

He was just a hotel staff member, so the arrest was naturally simple and smooth. The other party followed the police into the cage honestly.

Not even a hint of resistance, not even a verbal explanation or doubt, he just followed the police quietly with his head lowered.

If she wanted to sign, she signed, if she wanted to take something out, she took something out, and even after searching her body in circles, the police forgot to tell her to stop, so she just kept turning around.

In this situation, even Jiang Hai, who was still studying in the police academy, felt that Zheng Amei was 200% suspicious.

Chen Shu turned around and asked Jiang Hai, "Did you find anything suspicious about the deceased's transcript that you and Huang Mao checked earlier?"

"Brother Huang doesn't have a digital certificate, so we can't check the information. And this phone is also made of fruit, and the screen is locked, so we can't retrieve the records of social software at all."

"Harder than a treasury!" Jiang Hai said angrily.

Today's young people are accustomed to using mobile apps to contact friends through social software such as WeChat, including text messages and voice calls, all of which are implemented in the software.

Phone calls and text messages are basically not used at their age.

As for the safety of fruit mobile phones, it is indeed a headache, and there is no solution until now.

With that said, Jiang Hai looked at Ma Rongcheng and said sweetly: "Teacher Ma, can I borrow your digital certificate? I want to check the conversation between the deceased and Amei Zheng."

Ma Rongcheng's certificate was plugged into the computer at this time, but Jiang Hai still asked politely. This performance won Ma Rongcheng's great favor.

"It just works. By the way, can you do it? If you want to learn, I will teach you." After listening to Chen Shu's reasoning, Ma Rongcheng also seemed very interested and started to work step by step to recruit hotel cleaning staff. Zheng Amei’s data.

Men, when you get older, it’s better to be a teacher.

After half an hour of inquiry, except for listing Zheng Amei's recent contacts, the computer system did not analyze any useful information.

Due to the popularity of social software, the other suspect who keeps in touch with Zheng Amei may not appear on the call list, but may be on WeChat or QQ.

Some criminals with strong anti-reconnaissance capabilities often communicate internally through other foreign software that has not been officially licensed in China.

Large-scale software includes "Telegram", "Bluebird", "Tiktok", etc. These instant messaging software either have servers established abroad or provide point-to-point encrypted communication; secondly, you can also set up "self-destruct messages" to send messages at a certain time. The chat history will be automatically deleted.

The more ruthless guys go directly to Africa and Southeast Asia to purchase goods. The software there is even more lawless and directly arranges illegal VOIP traffic.

In the face of this new era of criminal methods, the traditional research and judgment of phone bills no longer means much, so the research and judgment of phone bills has not been paid as much attention as before.

Jiang Hai was a little discouraged, but Chen Shu didn't care. The focus of the case had to be on the people. Once the suspects were in place, there was nothing that couldn't be solved.

Interrogation is also the most basic skill that a criminal investigation police officer must master.

"Although WeChat is now popular and saves money, I don't believe they don't even make a phone call." Ma Rongcheng got angry. He typed the keyboard hard and said without looking back, "I'll try other methods. , let’s see if we can dig out the murderer behind the scenes. You guys should go do other things first, and I’ll let you know if there are any clues.”

On the one hand, the police force is insufficient and there are no extra police officers on duty to investigate the people in the call sheet one by one. On the other hand, Zheng Amei has been caught. If she can be taken care of, everything will fall into place.

Therefore, although both aspects of work have to be carried out, the focus of the case still has to be on the interrogation of Zheng Amei.

Chen Shu nodded: "Expert Ma, I'll trouble you here."

After the meeting, Chen Shu took Huang Mao, the police officer in charge of the case, to interrogate the suspect, Zheng Amei, in the interrogation room.

Before leading people into the interrogation room, Chen Shu quietly pulled Huang Mao aside and asked if there would be any procedural problems in such an act. After all, they were police from other provinces.

As a former border guard who had changed his job, Huang Mao naturally didn't know anything about it.

Chen Shu asked the other party to find someone to help with the case. Huang Mao continued to shake his head as expected.

This matter was done somewhat passively. After all, with the steady progress of the case, this case that was first misjudged as a "suicide" has become more and more likely to turn into a murder case.

Under such circumstances, the leadership of the Criminal Investigation Brigade remained silent. Chen Shu, who came from another province, couldn't figure out the problems for a long time.

"Hey, what are you afraid of!"

While Chen Shu was struggling, forensic doctor Old Tang walked in, shaking his head and holding his hands behind his back.

He smiled brightly: "Although we are forensic doctors, we are also real criminal policemen. With me and Xiao Huang here, we are two policemen who look like fake policemen. There is no problem with the procedures at all!"

When the case occurred, forensic doctor Lao Tang insisted on solving the case through autopsy. He was the one who put in the effort. According to his usual habits, the criminal police officers handling the case were eager to let him take the lead.

But the young criminal policeman from another province stopped his autopsy, saying that it was a pitiful end for the deceased, and that if there were other ways, he would not do it.

At that time, Old Tang laughed at the other party for being a people's policeman and being superstitious.

Later, when he heard Huangmao talk about the things that Captain Chen did in Nanjiang, he knew that he was a ruthless character who killed a group of KB members alone.

Such a cold-blooded guy who killed people without blinking an eye became particularly sympathetic here, which greatly changed Old Tang's impression of him. Thinking about it carefully, he also found it interesting.

At this point, Old Tang began to understand that Chen Shu's approach was not out of superstition, but respect and sympathy for the victims and their families.

Cold-bloodedness and warmth can appear in one person. Old Tang, who was already a little tired of studying the structure of the human body, suddenly found this complex human nature more fascinating, especially when it was a colleague who was also a policeman.

"Officer Chen, I'll leave it to you next." Old Tang politely extended his right hand into the house.

"No, no. Forensic doctor Tang, you guys are still in charge of the case. I'm just here to help." Chen Shu hurriedly said modestly, knowing that he couldn't steal the show in front of a forensic doctor known for his bad temper. This should apply to the whole country.

Old Tang smiled and bowed to Chen Shu, not at all like the forensic doctor who was known for his strictness in the unit.

If there were other police officers in the unit who were familiar with this forensic doctor, oh, yes, such as the yellow-haired man who just appeared at the corner of the corridor at this moment, he would look at him with a surprised look.

If you don't know, you might think Chen Shu is a long-lost relative of Old Tang.
