The police in Tang's world

Chapter 34 Alarm Recording
Yan Yu immediately felt that this was definitely not a simple robbery case, it was like a killer came to silence him, and then pretended to be a robbery, avoiding the direction of the police to deal with the case, and buying time to escape.

If you want to solve the case now, you still need to learn some specific information from the parties involved in the case, otherwise it is easy to go in the wrong direction of investigation.

But the head of the household's daughter is still receiving psychological training from a psychologist?How can I accept interrogation so quickly?
Besides, it will take time for Bu to conduct an identity check.

Yan Yu had no choice but to drive his Jimny back to the police station and wait in the office for a summary of the situation.

Thinking of something, Yan Yu immediately picked up the phone and called Bu.

"Bu, don't forget to send someone to check the insurance relationship and property status of the two deceased, and notify me immediately if you find anything."

Yan Yu kept praying in his heart that the things he suspected had better not be true, otherwise he was about to face a very complicated difficulty in obtaining evidence, which required high-level forensic technology for analysis.

Yan Yu directly called the main station and asked them to send a phone recording of the daughter of the head of the household when she reported the crime. Soon the recording was sent to her computer through the internal work account of the police station.

Yan Yu put on the earphones and listened to the recording of the call.

"Someone broke in! I heard a few bangs, like gunshots.

I don't know what happened, I was tied up upstairs. "

"Are you sure it sounded like a gunshot?"

"I'm not sure, I just heard a rapid thud.

My dad screamed before I called. "

"Is your mother downstairs too?"

"I can't hear anything from her."

Yan Yu turned his voice to the loudest, and the voice of the recorded call came into Yan Yu's ears very clearly.

And this official recording made the words more confirmed his own thoughts.

Yan Yu immediately copied a copy of the recording, and came to Lee with the backup. Lee had the same name as the murderer in the previous case. In addition, the last case only used Lee to check and monitor, without too much technical content. Lee expressed It's not very active either.

"Boss,"

Before Yan Yu arrived, Lee took the initiative to say hello.

"The support team doesn't need to be on the scene, you came quite early."

"Boss, you are here, how can I, as a subordinate, not be there? I have to learn from you, boss, and finally the royal family, bowing to pieces, and dying."

Although Lee is only Chinese, but thanks to the Chinese mother’s respect for Chinese culture, this guy is not like the vast majority of Chinese. He even speaks his mother tongue very generally. Except for everyday language, this guy will show off his Chinese skills when he has nothing to do. and strength.

"Don't flatter me. You're here, so I don't have to make a trip in vain. I need you to do something."

"Boss, you order."

"I need you to analyze a telephone recording."

Before Yan Yu could finish speaking, Le interrupted what Yan Yu was going to say next,
"Boss, I really can't do it, our support team simply doesn't have such talents and equipment.

As you know, boss, I have a background in information technology, and I can do well in the Internet. The team members under me are also two-handed, and sound identification requires very complicated professional skills and equipment. "

"You are from the technical department. Does the technical department of our police station have such identification ability?"

Lee shook his head. He himself is considered a rare talent in the technical department. The appraisal ability of the Chinatown Police Station is very low. Most of them are only responsible for collecting test samples on the spot and handing them over to the appraisal center in Bangkok for appraisal.

If such recording samples are to be identified, they still have to be sent to an identification center.

Things will be troublesome like this. If the technical department of the Chinatown Police Station can conduct an appraisal, Yan Yu can order the technical department to conduct an appraisal based on Yan Yu's current status in the police station.

But now?To submit to the identification center, this is not something that Yan Yu can do with a single order.

The status of people in the technical department is very different in the Chinatown police station. The rank of a forensic doctor is about the same as that of his own detective, and the leader of the technical investigation team is also about the same as him. of.

The forensic doctor of Peking Opera in Chinatown is a purebred Thai. He is in his 40s and has senior qualifications in the Chinatown Police Department. Fortunately, he is a neutral faction and never participates in the power struggles of these detectives.

It's still early in the morning to conduct an autopsy on the bodies of the head of the household and his wife, and I don't know what will be found.

As for the technical investigators, except for the team leader and a few people who graduated from the police academy's technical investigation major, the rest are veterans who have been in the police force for a long time and do not want to participate in the power struggle.

However, the matter of recording appraisal is complicated and complicated, and simple and simple.

Although the procedures are a bit cumbersome, but fortunately, the team leader of the technical investigation is a very talkative person.

When there was a case in the police station before, he obeyed the orders of the inspector-level people very much.

Yan Yu had no choice but to go to the technical department with his own backup.

People from the technical department are classifying the physical evidence and traces extracted from the crime scene in the room.

The physical evidence must be sent to the identification center for testing, and the traces will form a trace inspection report and be sent to the sponsor of the case.

"Pu Guai, is there something I need you to do?"

"Sir Yan, what do you want to say?"

"This recording, help me send it to the identification center for identification, and identify the volume of the voice in this recording at what distance the call is achieved."

"Okay, this is simple, and it can be realized by the appraisal center."

"About how long it will take, it may be before get off work tomorrow at the earliest."

"Is this identification difficult?"

"The technical difficulty is not difficult, but the identification center is open to all police stations in the city, and some private cases also involve identification, which is also done by them.

Therefore, the number of people doing identification is relatively large.Recording identification has never been a major category of identification, and technicians in this area have a lot of work in their hands. "

"That's it, sorry for the trouble, you can continue to work."

Puchai nodded, turned around and started the work at hand again.

Here, Yan Yu turned around and sent a WeChat message to Ao Zai.

"Ao Zai, help me find out. There was a burglary and shooting in Chinatown last night. Check in the gang to see if it was done by someone with a gang background.

Look for someone who sells stolen goods. Has anyone recently entered the business of selling chicken? "

Although the possibility is unlikely, in order to verify his conjecture, Yan Yu still wants Ao Zai to confirm.

If it was really a robbery, the robbers generally would not take the stolen goods in a short period of time in order to avoid the limelight.

In this seemingly robbery case, most of the stolen goods were cash. It is unrealistic to track a small amount of stolen goods, and it requires a lot of time and labor costs.

Therefore, Yan Yu just asked Ao Zai to check briefly.Maybe when this line finds someone, Yan Yu has already arrested the real culprit.
