Detective: I can see the criminal record

There were a lot of surveillance videos, and Cen Lian didn't have any clear purpose. He just took a notebook and kept it nearby, ready to record the criminals he saw at any time.

The surveillance cameras in this kind of brothel can capture far more than just the murderer who killed the five people who fell into trouble. There may also be all kinds of criminals. After all, in this kind of place that seems to be operating properly but actually does all kinds of business, it is also the favorite trading place for some people with dirty backgrounds.

Wu Qiushan saw that Cen Lian began to get into work mode, so he quietly walked aside to deal with other things.

After being seconded to the Municipal Bureau, although Wu Qiushan also had a certain degree of freedom, he still focused on handling the cases of the Municipal Bureau more often.

It is difficult for a criminal investigation technician like him to be completely idle.

Tang Hua looked at the piles of surveillance videos. It is estimated that Cen Lian has no time to care about other cases these days. It happened that the DNA in Chen Nan's case was sent to Yunnan Province for matching. It is estimated that there will be no results for the time being. He may take the opportunity to take advantage of it.

Unfortunately, Tang Hua's beautiful fantasy did not last until lunch time and was defeated by the ruthless reality.

The third squadron received a case of intentional injury. Tang Hua followed Wang Yuanteng and Qi Yan to work, leaving Cen Lian alone in the office to study the surveillance of the headless corpse case.

When Cen Lian rubbed his neck and raised his head to move his cervical spine, he found that most of the people in the office had gone out.

He looked at the book in front of him with some regret.

Although he had not seen any clues related to the headless corpse case, watching the surveillance for a morning was enough for him to find some criminals.

The most important of them were those involved in pornography.

In addition, he found a very interesting tomb-robbing gang.

Eight years ago, this group of people often traded in this nightclub. Out of curiosity, he checked the current situation of this group of people. As a result, there were only six people in the gang, four of whom had died and their accounts were closed, and two were sentenced to fifteen years and are still in prison.

It is not known whether the four people died from cannibalism or tomb robbery.

After marking several robbers with criminal records, Cen Lian looked at the progress bar and found that he had only watched five or six days of surveillance in this month.

This efficiency is a bit low.

Cen Lian simply set up a split screen, set the computer to nine-square grid mode, and played nine surveillance videos with different perspectives at three times the speed at the same time.

Anyway, he mainly watched text bubbles.

At lunch time, he put lunch on the table for Tang Hua and others who went out to handle the case, and Cen Lian continued to watch the video surveillance.

At around three o'clock in the afternoon, Tang Hua came back with a tired face.

"It has to be my brother Cen," he opened the lunch box and ate a lot, and then he had time to say a few words, "Today's case is really hard, the two people quarreled after a scratch, and then neither of them gave in, and finally they got angry and fought. Now it's okay, after being discharged from the hospital, they have to be sent to the forensic doctor for injury assessment."

"So you are mainly to stop the fight," Cen Lian paused the surveillance video, "the case should be closed soon."

Tang Hua suddenly had an ominous premonition.

"Don't tell me there are no clues in the headless corpse case, but you can see other cases from the surveillance." He made wild guesses based on his understanding of Cen Lian.

Cen Lian showed a kind smile.

Tang Hua almost choked to death on his food.

When Wang Yuanteng and Qi Yan came back together, they saw Tang Hua pretending that he saw nothing.

"What happened?" Wang Yuanteng was a little curious.

Cen Lian handed him a stack of A4 paper.

"When I watched the surveillance, I found a few people with some problems. These people are related to their identities and previous cases, all of which are robbery and theft. It's the end of the year, so let's use them to boost performance." His smile became more innocent.

Wang Yuanteng: ...

"Do you have evidence for these cases?" Qi Yan asked more seriously.

"Some have, some don't," Cen Lian couldn't spend time finding evidence for everyone, "You can deal with the ones with evidence first, and take your time with the rest."

Wang Yuanteng sighed and took the stack of papers, "From what you saw in the surveillance, our team will probably become a money-spending boy soon."

Qi Yan flipped through it and found that the few people with evidence were directly matched by DNA in the database by Cen Lian.

Wang Yuanteng chose to go to dinner first. Anyway, these criminals were eight years ago, so there was no need to spend so much time.

Some cases were not complicated in the first place, but they might just not be taken care of at the time.

After handing over a batch of criminals sorted out in the morning, Cen Lian continued to study the surveillance.

It was not until after nine o'clock in the evening that he finally saw the text bubble he wanted flash by on the computer that had turned into a 16-split screen.

He was the only one left in the office at this time, and even Yuan Chenxi had gone off work.

Cen Lian straightened up and found the surveillance video.

This is a nightclub called Haoyan. Now the boss was sent to prison for involvement in organized crime, and it has closed down, but it can be seen that it was a very lively place at that time.

This is where the second deceased worked.

Cen Lian was quite impressed with the second deceased. He was a male fallen person, just over 20 years old. According to the household registration information, he came from a remote rural area. After going to the city to work, he was introduced to this nightclub by someone. He was killed and beheaded less than a year after he worked there.

He was the only son in the family. After his death, his parents' hair turned white overnight. They came to the police station several times to ask if the murderer had been found, but they have not come again in recent years.

As for the flashing text bubble, although Cen Lian knew who the murderer was, he still had no idea why he committed the crime.

[Name: Tu Lou]

[Gender: Male]

[Age: 45 years old]

[Criminal record: long-term illegal possession of guns

3085 days ago in Kang'an City, killed Hao Xingzong

3087 days ago in Kang'an City, killed Zhao Yang]

[Prison record: None]

There were five victims in the 527 headless corpse case, but the two lives in this person's hands were only the two male victims, which means that there is not only one murderer in the five cases.

According to the current situation, it is more likely that there are two murderers.

But who is this Tu Lou, and why does he have a gun in his hand? !

As we all know, once a criminal case involves guns, it will become extremely complicated.

Cen Lian entered Tu Lou's name and quickly found the household registration record.

Then he was even more confused.

Tu Lou is not a native of Kang'an City, but from Yunzhong City, a prefecture-level city under the jurisdiction of Xingxi Province, another neighboring province of Yunling Province. His identity is even more ordinary, just an ordinary private enterprise employee.

More than eight years ago, he was only 37 years old. It is reasonable to say that he would hardly have any intersection with Hao Xingzong and Zhao Yang.

Unless he had contact with these two people in Kang'an City.

But there was no Tu Lou in the list checked by the special investigation team in this case.

This means that he has never appeared in the "customer list" and transaction records of these two people, nor does he exist in their network of relationships.

But where did he get the gun?
