After reading Jing Wu's case, Xiao Ran picked up the second file.

The second person who was killed was named Sang Keke, 26 years old. He was killed on August 31 of that year, one month away from the Jingwu case.

After Sang Keke died, he was also tied into the shape of ‘Z’.

However, unlike Jing Wu, Sang Keke was not strangled to death, nor was shed in the air. Instead, she was stabbed into the heart with a clean knife. After death, she was tied to the word "Z" and knelt on the floor of the rental house.

No one noticed Sang Keke after he was killed.

Later, when Sang Keke worked in the factory, he found that the person had been absent from work for two days, and no one answered the call from the workshop manager, so he kindly reported to the nearby police station.

At that time, the surveillance system was not as developed as it was at this time, and Sankoko lived around the factory, and the location was relatively remote and there were fewer cameras.

After the incident, the local public security bureau immediately set up a special task force to investigate the case. Later, he learned about the Jing Wu case in H City. So under the organization of the provincial department, the police of the two cities established a joint task force.

By the way, Sangke is from Shao City, not a senior executive of a company, and there are basically no friends around him.

There was no word "otaku" 15 years ago.

But based on the current definition, Sang Keke was indeed a standard otaku at that time. He worked silently and locked himself in a rental house after work, playing with the computer he bought with all his savings, and slandering people on the Internet.

After checking Sang Keke's computer, Shao City police found that in the extremely underdeveloped network environment at that time, Sang Keke was so angry that he was embarrassed and angry that there were more than 400 people threatening to kill him.

On the Internet, who is afraid of whom?

So whenever an angry person asked Sang Keke about his address and wanted to come and be him, Sang Keke also brought the address back without hesitation.

Of course, Sang Keke was actually scared, how could he return his actual address? But you can't be cowardly on the Internet!

After checking all Sang Keke's reply, the local police found that the address Sang Keke told was the address of Chengdong Sewage Plant, and his real address had never been disclosed.

Then he was killed.

Later, the news of Sang Keke's murder was also reported to the posting station where Sang Keke often slandered people.

I heard that the most hated troll in the posting site died. One of the big guys inside even opened a Sancai Building, where everyone can reply to their bank card account in the post, and then the big guys send 300 yuan each.

After learning about this situation, the Shao City police also found the big guy who was scattering money, but they were very happy to celebrate.

In the end, the police in both cities found nothing.

Xiao Ran put down the file of the Sang Keke case and stared at the desktop and fell into deep thought.

As for Sang Keke himself, a young man who is usually timid and afraid of things, and is even cowardly enough to dare to speak loudly with others, obviously has a very small possibility of making enemies with those around him.

If the theme of the smiley face case was ‘hate’, then the one who made enemies with Sang Keke would probably be from the Internet.

However, Sang Keke never leaked his address. Assuming that the murderer was positioned through IP, the one who could do this in the network environment of that year should be a master.

However, the police then traveled all over the country and found hundreds of people who had sprayed with Sang Keke one by one, and they were all eliminated one by one.

Xiao Ran pressed his forehead and forced himself to read the last case in his smiling face back then.

The third case occurred in H City, and a couple died. The murder was on September 30, a month after the Sang Keke case.

The two were killed in the same way as the Sang Keke case. They were both fatally killed by a knife. After their death, they were tied to the word "Zi" and placed against each other on the floor.

But the only difference is that Sanco was pierced through the heart, while the lovers were pierced through the throat.

When the couple was killed, they had been living together in the house they bought for a year and were preparing for marriage. However, when the man's mother went to call them for breakfast the next day, she found that her son and prospective daughter-in-law died in the wedding room.

At this time, the Municipal Bureau was still having a headache for Jing Wu's desk. After receiving this report, everyone's hearts were ignited.

If you walk by the river often, how can you not get your shoes wet?

If these three cases were all done by the same person, the task force firmly believes that no one can do all of them perfectly!

However, the final result still disappointed the task force. After sorting out the entire case, nothing was found.

Among the three cases of "一", the task force of the two places did not even collect half a footprint or a single fingerprint, which was incredible.

However, the only thing that can be confirmed is that the victims of the latter two cases died of the same knives, and the ropes used in these three cases and the knots tied are the same, so the task force believes that the three cases should be done by the same person.

So, if the same person had committed three consecutive kills 15 years ago, why did he strip the deceased from his clothes and hang it in the air when he committed the first crime? What is the purpose of doing this?

Is it a certain convention or a certain ceremony?

Xiao Ran looked at the photos in the file. When he saw the photos of the knot in the file, he suddenly thought of the knot tied to Fan Changjie.

15 years ago, the rope tied to four people was 8 bytes, simple and neat, and even a bit beautiful.

Xiao Ran clearly remembered that the most common knots tied to Fan Changjie's neck and ankles this time were all the most common knots, and they were tied several times in a crooked manner.

In other words, if the knot on Fan Changjie's body was not done by the murderer on purpose, then the murderer this time should not be the criminal 15 years ago.

Xiao Ran narrowed his eyes. Assuming that the murderer was imitating the case of that year, how did he learn such superb anti-reconnaissance methods?

There is still an organization behind it that is mass-creating smiling killers.

This thought flashed through Xiao Ran's mind.

Xiao Ran stood up and put the file back to Lei Kang's office. When he came back, he saw that the technical area was brightly lit and everyone was busy nervously, so he didn't go over to disturb him.

After looking at the time, it was almost 2 o'clock in the morning.

Xiao Ran went to the cabinet to get the coat and blanket, then went to the duty room to find a small bed, lie down with the clothes, and briefly replenished his sleep.

At 7:30 the next morning, the newly established task force held its first case analysis meeting in the conference room.

"The time of death of the deceased was initially determined to be October 17, 6 days ago."

Xue Qingxia first read out the preliminary analysis report: "...The deceased had no scars on the body and no toxic substances in the body. It was determined that he died of mechanical asphyxiation. There was a small amount of textile fiber in the gap of the deceased's nails. As for whether it came from the murderer's clothes, it is impossible to judge. Judging from the marks on the deceased's neck, the murderer's tools were used to tie the victim's rope."

"We extracted a small amount of artificial leather particles from the ropes and judged that the murderer should have worn gloves when committing the crime, but no traces of available fingerprints, footprints, etc."

The technical team then added: "But after a rough look at the surveillance, we found that the surveillance one night was missing from the surveillance one week before the victim's death..."
