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

The second victim was named Sang Keke, 26 years old, and was killed on August 31 of that year, a month after the Jing Wu case.

After Sancoco's death, he was also tied into a zigzag.

However, unlike Jing Wu, Sang Keke was not strangled, nor was he stripped of his clothes and hung in the air, but was cleanly stabbed into the heart, and after death, he was tied into a 'zigzag' and kneeled on the floor of the rental house.

No one noticed that Sancoco had been killed.

Later, it was still the factory where Sang Keke worked, and it was found that the person had been absent from work for two days, and no one answered the workshop supervisor's call, so he kindly reported to the nearby police station.

At that time, the monitoring system was not as developed as it was at this time, and Sang Coco lived around the factory, which was relatively remote and had fewer cameras.

After the case was discovered, the local public security bureau immediately set up a special task force to investigate the case, and later learned about the Jingwu case in H City, so under the organization of the provincial department, the police of the two cities set up a joint task force.

In other words, Sang Keke is a native of Shaoshi, not a corporate executive, and he doesn't even have friends around him.

Fifteen years ago, there was no word for 'otaku'.

But if you use the current definition, Sang Keke at that time was indeed a standard otaku, usually working silently, locking himself in a rental house after work, playing with the computer he bought with all his savings, and spraying people on the Internet.

After checking Sang Keke's computer, the Shao City police found that in the extremely underdeveloped network environment at that time, more than 400 people were sprayed by Sang Keke into anger and threatened to kill him.

On the Internet, who is afraid of whom?

So whenever an angry person asked Sang Keke for his address and wanted to come over to make him, Sang Keke did not hesitate to return the address.

Of course, Sang Keke was actually stunned in his heart, how could he reply to his actual address? But he couldn't be cowardly on the Internet!

After the local police checked all of Sang Keke's replies, they found that the addresses that Sang Keke told were all the addresses of the Chengdong Sewage Plant, and his real address had never been leaked.

Then he was killed.

Later, the news of Sankeke's killing was also spread to Sankeke's sticker station, which often sprayed people.

I heard that the most hated troll in the post station hung up, and one of the big guys in it even opened a scattered wealth building, everyone can reply to the bank card account number in the post, and then the big guy remits 300 yuan on each floor.

Knowing this situation, the Shao City police also found the big man who scattered money, and the result was that people were happy to have money and 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 in deep thought.

As far as Sang Keke himself is concerned, a young man who is usually timid and afraid, and even too cowardly to speak loudly to others, is obviously very unlikely to have a grudge against the people around him.

If the theme of the smiley face case was 'hatred', then the enmity with Sang Keke is likely to come from the Internet.

However, Sang Keke never divulged his address, assuming that the murderer was located through IP, with the network environment of the year, the person who could do this should be a master.

However, after that, the police traveled all over the country and found hundreds of people who had sprayed with Sancoco one by one, and they were all eliminated one by one.

Xiao Ran pressed his forehead, cheered up and flipped through the last case with a smiling face that year.

The third case occurred in H City, where a pair of lovers died, and the time of murder was September 30, a full month after the Sang Keke case.

The two were killed at the time of similar to the Sang Keke case, both were fatally stabbed, and after death, they were tied into a 'zigzag' and placed on the floor with their backs to each other.

The only difference, though, is that Sancoco was pierced in the heart, while the lovers were pierced in the throat.

When the lovers were killed, the two had been living together in the house bought by the man for a year, and were preparing to get married, but the next day when the man's mother went to call the two to breakfast, she found that her son and prospective daughter-in-law had died tragically in the marriage room.

At this time, the city bureau was still having a headache for Jing Wu's case, and after receiving this report, everyone's hearts were filled with hope.

I often walk by the river, how can I not get my shoes wet?

If all three cases were the work of the same person, the task force firmly believes that no one can be perfect!

However, the final result still disappointed the task force, and the whole case was sorted out, but nothing was found.

In the three cases, the task forces of the two places did not even collect half a footprint or a single fingerprint, which is simply incredible.

However, the only thing that can be determined is that the victims in the latter two cases were killed by the same knife, and the ropes used and the knots used in the three cases were the same, so the task force believes that the three cases should have been committed by the same person.

So, if the same person committed a triple murder 15 years ago, why did he strip the deceased and hang him in the air when he committed the first crime, and what was the purpose of doing so?

Is it some kind of custom, or is it some kind of ritual?

Xiao Ran looked at the photos in the file, and when he saw the knots in the file, he suddenly thought of the knots tied to Fan Changjie's body.

15 years ago, the ropes tied to the four people were all 8 bytes, simple and neat, and even somewhat beautiful.

And Xiao Ran clearly remembered that this time the ties to Fan Changjie's neck and ankles were the most ordinary dead knots, and they were tied crookedly several times in succession.

In other words, if the knot on Fan Changjie's body was not intentional by the murderer, 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 the year this time, then how did he learn such superb anti-reconnaissance methods?

Or - there is an organization behind the scenes that is mass-producing smiley killers.

This thought flashed through Xiao Ran's mind.

Xiao Ran got up and put the file back in Lei Kang's office, and when he came back, he saw that the technical area was brightly lit, and everyone was nervously busy, so he didn't bother.

Looking at the time, it was close to 2 o'clock in the morning.

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

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

"The time of death of the deceased is preliminarily determined to be October 17, six days ago. ”

Xue Qingxia first read out the preliminary report: "...... The deceased had no injuries on the surface of his body and no toxic substances in his body, and was judged to have died of mechanical asphyxiation. There were a small amount of textile fibers in the cracks of the deceased's fingernails, and it is impossible to determine whether they were from the murderer's clothing. Judging from the strangulation marks on the neck of the deceased, the murderer's tool was the rope used to bind the victim. ”

"We extracted a small amount of artificial leather particles from the rope, and judged that the murderer should have been wearing gloves when committing the crime, but we did not extract usable fingerprints, footprints and other traces. ”

The technical team then added: "However, after a cursory review of the surveillance, we found that one night of the surveillance in the week prior to the victim's death was missing......
