Detective: I can see the criminal record

These days, not many people still take the bus. Social workers who need to go to work usually pay by swiping cards or scanning codes. It is more difficult to find a few coins from them than not working overtime.

The elderly and children each have preferential bus cards, and rarely pay with coins.

So at the end of the day, the total amount of banknotes and coins received by a bus is not much, and the one-yuan banknotes are even rarer.

When Cen Lian came back with the money, the expert invited by Wu Qiushan had not left yet.

"Brother Yue, hurry up, the murderer may have paid for the bus." Cen Lian immediately grabbed Wu Qiushan when he saw him, and roughly explained the cause and effect of the matter while he was confused.

Wu Qiushan was very fast at extracting information and already understood Cen Lian's current requirements.

"Teacher Ren, can you please wait a moment." Wu Qiushan immediately turned around to look at Ren Xingyuan.

Cen Lian only then knew who the fingerprint expert invited by Wu Qiushan this time was. Speaking of this person, they all knew him. He had given them several lectures when he was studying at the police academy before. He was a top expert in their province.

"Come on, you've already done it for a day." Ren Xingyuan is nearly sixty years old and is a real old expert. Recently, he happened to be giving a lecture at the police school in Yunling Province. Wu Qiushan invited him after hearing about it.

Ren Xingyuan picked up the tools and carefully extracted more than 20 one-yuan banknotes provided by Cen Lian.

After spending more than an hour to extract all the fingerprints, he entered the fingerprints into the computer while pushing his glasses to look at Cen Lian carefully.

"You are Qiu Shan's classmate," he confirmed after looking at it for a few times, "I remember you. In your class, you and Qiu Shan were always the top two in your college in all aspects."

Tang Hua's eyes widened. He knew which school Cen Lian graduated from. He thought he was assigned to the police station during the public security joint examination because of his poor grades. Unexpectedly, he was still a top student? !

Cen Lian showed a somewhat embarrassed smile.

"I didn't expect Teacher Ren to still remember me."

If Teacher Ren knew that I ran to the police station to play badly after graduation, I don't know how he would feel.

"Haha, you two are both unwilling to study for a master's degree. Old Wei has complained to me several times, so I remember you." Ren Xingyuan said slowly.

At this time, Cen Lian and Wu Qiushan were both feeling guilty.

Fortunately, the fingerprints that had been entered interrupted Ren Xingyuan's conversation with them.

Cen Lian and Wu Qiushan both came to the computer to look at the fingerprints.

This time, a total of dozens of fingerprints were entered. Ren Xingyuan operated the system and compared these fingerprints with the fingerprints extracted from Chu Yulin's body one by one. He stopped when switching to the thirteenth fingerprint.

He frowned for a while, and then kept enlarging and moving the remaining fingerprints on Chu Yulin's body, and soon relaxed his brows.

"Yes, this is it." After confirming the fingerprint, Ren Xingyuan directly threw the complete fingerprint that matched the comparison into the fingerprint database. Soon, Yang Xu's name appeared in front of his computer.

Tang Hua was already a little numb.

He actually had no idea why Cen Lian had accurately selected a suspicious person from the thousands of passengers who had taken bus No. 16 on October 22, and successfully matched the fingerprints with those on the body.

Is this the world of academic masters?

Tang Hua, who came from a second-tier police academy in the province, suddenly felt the disparity of the world.

"I will fill out the fingerprint identification report and send it to you in a while. At this point, we can arrest people directly." Ren Xingyuan has been doing criminal technology work for decades, and he knows very well that as long as the fingerprints are compared, the probability that Yang Xu is the murderer is very high.

When Cen Lian saw Yang Xu's information appear, he finally breathed a sigh of relief.

"Teacher Ren, I'll go upstairs to find our captain first." Cen Lian politely greeted Tang Hua, who had not yet recovered, and left the Criminal Investigation Technology Department on the first floor, and ran to the second floor to find Tan Tonghui.

"Are you looking for Captain Tan?" Yuan Chenxi saw them coming in from a distance.

"We have compared the fingerprints on the body and found out who it belongs to. Where is Team Leader Tan?" Cen Lian was still a little anxious. This Yang Xu was obviously a vagrant and committed crimes. It was unknown whether he was still in Yunling Province.

"Team Leader Tan is out. Sister Liang is in the office." Yuan Chenxi said while calling Tan Tonghui. Cen Lian and Tang Hua found Liang Xuan and reported in detail that they had successfully matched the fingerprints extracted from the banknotes with the fingerprints on the body and found the fingerprint owner in the fingerprint database.

Liang Xuan paused.

"Give me the fingerprint report as soon as possible and notify the whole team to hold a meeting." Liang Xuan put down other matters in his hands without hesitation and walked into the meeting room without looking back.

Tang Hua touched the back of his head.

"Has this case been solved?" He suddenly felt unreal.

"The murderer has been basically identified," Cen Lian was very confident in the system, "Now we are in the process of arresting him. We don't know where Yang Xu is now."

"It will be easy with his photo," Tang Hua stood there, "In fact, I still don't understand the cause and effect of the case, but we found the murderer under such circumstances."

He felt a little puzzled.

It was as if the murderer was suddenly picked out of the crowd by Cen Lian.

"After arresting Yang Xu, you can hear any cause and effect you want." Cen Lian patted his shoulder and turned to see Wu Qiushan coming to the second floor with the fingerprint identification report.

"Gold will always shine," Wu Qiushan handed the fingerprint report to Cen Lian, "Also, give up your impossible dream of becoming an astronomer."

Cen Lian looked up at the sky helplessly, "To be honest, I don't really want to shine like this, but God doesn't agree."

Tang Hua suddenly had the urge to hit Cen Lian on the head with a brick.

But before that, he still gossiped to Wu Qiushan about why Cen Lian went to the police station to live.

"He had a good score in the college entrance examination. He originally planned to apply for astronomy at Jinling University, but his father forced him to apply for our school in the early batch. His father said that he had to go to the police academy to become a policeman, so he had no choice but to go. After graduation, he became like this." Wu Qiushan shrugged, "Some people tried to resist being a policeman by playing badly, but they still failed."

Cen Lian stopped Wu Qiushan from continuing to expose his past.

"Brother Yue, that's enough," he quickly pushed Wu Qiushan out the door, "There will be a meeting later, and our case is almost solved. You should go back to your municipal bureau."

Wu Qiushan glanced at Cen Lian.

"Go back to my city bureau? Just wait, I'll see how long it will take you to get yourself into the city bureau."

Cen Lian: ...

Why is this person's words so hurtful?

Tang Hua secretly gave Wu Qiushan a thumbs up.
