Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Yang Lin put the relevant specimens into the instrument and turned around to do other things.

Beep beep!

Suddenly, a rapid alarm sounded, startling the four people who were working!
The alarm sounded rapid and loud, and several people subconsciously looked up at the source of the sound.

"Yes?"

Then, Yang Lin rushed over.

View the instrument's identification results.

The other three followed.

In order to save time, Liu Guodong and his four colleagues first identified the organic matter when conducting trace evidence analysis on the entire sculpture.

Only once the organic matter has been identified can the organic matter itself be identified and analyzed again.

Otherwise, if they were to conduct a comprehensive trace evidence identification on a specimen right away, the workload would be too huge, and they would not be able to finish it in a month, let alone a year.

"167 specimens!"

Yang Lin took a look at the specimen inside and checked it. The number next to it was exactly specimen No. 167 that he had just placed in the instrument.

The alarm sound of the detection instrument is the detection sound prompt tone when organic matter is detected.

"Hurry up and conduct a comprehensive analysis of this specimen."

Liu Guodong ordered.

Even if organic matter is detected, it does not necessarily mean that we know what it is, so we need to further test it. It may be hair, nails, or dandruff.

But no matter what it is, as long as the specimen is fully identified again, we will be able to find out what it is and conduct a detailed analysis of the components inside. If we are lucky, we may even be able to extract some DNA information.

It can be said that hard work pays off. After re-identifying and analyzing specimen No. 167, Yang Lin came to the conclusion that there was a bit of human epidermal tissue hidden in it.

In other words, dandruff.

Although it is very small, the DNA information inside can be obtained through trace evidence identification and analysis.

When Zhang Hui got the news, he jumped up from the sofa.

"Are you serious?"

The criminal police officer nodded heavily: "Deputy Captain Liu called personally and said that they have found the DNA information and are now checking the system. If the other party has entered the information..."

Before they could finish their words, they heard a shrill alarm coming from the survey office next door.

Grass!
I rushed out in one step and the alarm sounded, which meant that the DNA comparison was successful.

Apparently, other people also heard the alarm, and many investigators rushed to the on-site investigation office.

"Found it?"

Zhang Hui’s first sentence.

Yang Lin, who was sitting in front of the computer, nodded heavily. He didn't expect that the comparison was actually successful.

"Found it!"

Yang Lin, who was sitting in front of the computer, had big bags under his eyes and his eyes were red from staying up late, but he was very excited.

He has been working in the Criminal Investigation Detachment for quite some time. After leaving Luchuan, he has been here for nearly a year.

To be honest, Yang Lin spent the first half of this period learning some experiences and skills passed down by the older generation from Yang Sen, Lao Bai and Liu Guodong.

Therefore, Yang Lin did not get into the state quickly at the beginning. He was still an apprentice and could not directly participate in the on-site investigation work.

Fortunately, Yang Lin was originally a graduate of a professional school and his academic performance was also good back then, so after a period of adjustment, he quickly found the feeling. In addition, with the hands-on teaching of Liu Guodong and others, and with some difficult problems, he often called Lu Chuan privately, so his skills improved rapidly.

After about half a year here, I was gradually able to do some on-site investigation work independently, such as fingerprint identification and on-site photography.

But this time, it was the first time that I was involved in such a big case and obtained important clues.

Yang Lin had a feeling that he was involved in the most important part of the whole case.

Yang Lin participated in the entire process, from crushing the plaster statue and then classifying the specimens, to identifying and analyzing the inorganic and organic substances in the specimens, and collecting DNA information after the dandruff was found. Now, the information is matched in the system and the match is successful.

To put it bluntly, if the owner of this DNA information is the murderer, then the case was solved by the Current Publication Office.

During the 20 days of solving the case, Yang Lin did not return home once. He slept in the office or even in the laboratory.

He did not miss any part of the whole process, so he could be said to have made the first contribution to solving the case. If he could really solve the case, he would probably be awarded another third-class merit.

Third Class Merit...

Yang Lin has it, which he got when he was helping Lu Chuan solve a case.

But this time it's different.

This was obtained entirely by Yang Lin's own efforts. Although Lu Chuan's suggestion was involved, the specific work was still done by Yang Lin and his team themselves.

After hearing the alarm, not only Xinglu came over, but Qin Yong also got the news and immediately ran over from his office.

"found it?"

In response to Qin Yong's inquiry, Liu Guodong immediately said, "The match was successful. He is a person with a history of intentional injury."

Criminal record?

That's basically the murderer without a doubt.

Skin scraps of a person with a criminal record were found in the plaster that sealed the body.

Then the possibility that the other party is the murderer is basically 100%.

"Zhang Hui, find him immediately and bring him back to me!"

"Yes!"

Now that we have discovered the other party's share, it would be easy to catch him back.

The personnel information soon reached Zhang Hui's hands. The other party is still living in Haizhou City and in the High-tech Zone.

Zhang Hui called Lu Chuan.

Lu Chuan didn't expect that he would actually find clues in the plaster and identify the other party.

Since it was within the jurisdiction of the High-tech Zone, Lu Chuan personally led his men to cooperate with Zhang Hui to carry out the arrest operation.

Meimei Car Wash.

"It has been confirmed. The person is inside."

Zhang Hui, Lu Chuan and others had already figured out the situation of the criminal suspect.

The other party is called Wang Biao. He was imprisoned for two years for intentional injury 10 years ago.

Now Wang Biao has opened a car wash, and it seems to be quite large.

Just now, Zhang Hui sent someone to investigate pretending to wash the car and confirmed that the boss Wang Biao was inside.

"Okay, follow the plan and act now!"

A dozen criminal police officers rushed into the office where Wang Biao was playing mahjong with a few others.

The other party was also quite alert. When he saw this group of people rushing in, he immediately overturned the table and was about to jump out of the window nearby.

However, it would be a joke if Zhang Hui and Lu Chuan personally took action and still let him escape.

"Hold them!"

To the surprise of Lu Chuan and Zhang Hui, the other party actually told a few people playing cards on Taobao to stop their group, and the other party actually stood up and prepared to take action.

"Don't move! Police!"

police?

I grass!

The three people who were playing cards with Wang Biao saw the black muzzle of the gun and dared not take action.

Everyone lay down on the ground obediently. Before Wang Biao could rush out from the window, Lu Chuan came up and kicked him back.

"what is it call?"

After handcuffing them one by one, Zhang Hui asked questions sternly.

Lu Chuan was very ruthless and kicked Wang Biao in the chest. The other party was now handcuffed and was still retching and coughing, unable to speak at all. (End of this chapter)
