Three people and one ghost solved 43 mysterious cases.

During the investigation, the police linked this case to the "falling" murder case on the side of the national highway in January.

Both old women had their stockings ripped off.

They didn't know each other, they couldn't get along with each other, and they definitely had no common friends or enemies.

The police judged that the two cases were related, and the stockings were related.

But if you can’t figure out the murderer’s purpose, is that a perversion?

I found a psychology expert from the police force. After reading the information on these two cases, the psychologist came to an inference:

The murderer may be a person with an antisocial personality and a special hatred for old women.

"Is the murderer a stocking addict?" the police asked.

Psychologists think not. The psychologist explained:

If the murderer is a stocking fetishist, most of them are obsessed with feet and stockings. After committing the crime, they may tear the stockings, perform some more filthy acts, or take away the stockings.

But this murderer, if he is a serial murderer, obviously his motives are not that.

He probably hates one type of people in particular - ladies in the middle-aged and older age groups.

Psychologists have read the information of the two women who were attacked. They are both somewhat "strong" people. For example, they can argue about some things and easily get into quarrels with others.

Maybe it was something he said inadvertently and unintentionally that offended the murderer.

The murderer probably had a deep shadow for this kind of people, so he killed him violently. After committing the crime, his act of tearing off his stockings was just a way of venting his anger.

You see, the two old women were neatly and clearly dressed in traditional clothing at the time of the crime.

Therefore, pulling off the stockings represents an insult to their "traditional and conservative" style, making them "unclean and untidy" until they die.

"It's hard to explain, but maybe this is the murderer's twisted purpose." The psychologist finished.

.

In June 2002, the third murder occurred.

The body was found under a bridge. The deceased was called Ms. Ma, 47 years old, and her occupation was a vocational high school teacher.

The body was lying crookedly on the river bank under the bridge. He died from a heavy blow to the head. The cause of death was suffocation. Stockings were pulled.

Some rusty powder was found on the back of the body, which confirmed that the murder weapon was most likely an old hammer.

The deceased's nails and hands showed that they had been wiped.

No footprints or fingerprints were found by the river. Likewise, there is no surveillance in this area.

This is not the scene of the first-line crime, but the scene where the body was dumped. The murderer obviously made precise arrangements.

He killed Ms. Ma beforehand, then chose night to transport her to this remote bridge, tore off her pantyhose and threw her from the bridge.

The killer may have had a car.

The police again went to the psychologist, who said it had escalated.

The murderer's methods of murder escalated.

If it is the first case, an old woman "fell" and died on the side of the national highway.

It must have been the murderer's first crime at that time. Due to impulse, he pushed the old woman to the ground. The old woman's head bled excessively.

The murderer was so panicked that he was afraid that the old woman would see his face, so he banged the old woman's head against the rocks on the ground.

He may have wanted to turn it into a robbery scene, but he couldn't find any money after searching for a long time.

The murderer glanced at the old woman again, and blood flowed from the back of the old woman's head. The murderer was still very angry. Maybe the old woman made the murderer feel disgusted, so he bitterly tore off the old woman's jumpsuit.

At that moment, he seemed to get a twisted pleasure from catharsis.

After that, he fled. When he returned home, he must have been watching the news for a long time, and found that the news did not report on this case.

After a few months, the murderer calmed down and felt that everything was fine.

It wasn't until May that the murderer met the No. 5 woman in the alley.

He may not have known the woman, and she had never spoken to the murderer.

The woman's dress, appearance, and certain conditions should have once again aroused the murderer's desire to commit crime.

He followed the woman to the alley, took out the murder tool, most likely the rusty hammer, and hit the woman hard on the head, then took off his socks and ran away.

This time, he was still not found.

But with the two crimes, his inner desire to commit crime became stronger and stronger. He seemed keen on revenge against this kind of old woman - a woman who dressed in traditional clothes but spoke a bit meanly.

So he escalated and orchestrated the third murder of Ms. Ma.

He should have some way of contacting Ms. Ma. For example, the murderer is a salesman, repairman or the like.

He gained the trust of Ms. Ma, who got into the murderer's car.

Then in the car, the murderer strangled Ms. Ma to death. After covering her up, he hit Ms. Ma on the head again with a hammer.

This may be done to achieve a "fit" with the murder methods of the first two cases. In other words, the murderer has formed a fixed "pattern" for his own murder methods.

Then, he drove to a hidden bridge and threw Ms. Ma off the bridge.

The second case and the third case were only one month apart.

This proves that the murderer was at the peak of his crime.

"You must catch the murderer as soon as possible. He will definitely commit crimes again." The psychologist said.

The police dispatched a large number of police officers and identified the suspect as a male, about 175cm tall, with a car, and may be a salesman, insurance agent, repairman or other occupation.

I had a brief encounter with Ms. Ma during her lifetime.

But after looking for more than 100 suspects, still no one was found.

Just half a month later, the fourth crime occurred again.

.

This time, there was a cable renovation in the community. Some underground cable wells needed to be relocated. When several repairmen opened a manhole cover, they discovered a female body.

The characteristics of the female corpse underground are still consistent. She is a middle-aged woman, neatly dressed, her stockings were torn off, and she died more than ten days ago.

In other words, the actual interval between the third and fourth cases was less than a week.

If it hadn't been for cable modifications, the deceased woman might not have been discovered for a long time.

This time, it was upgraded again.

At the crime scene, a half-drunk Coke can was left under the manhole cover. Fingerprints, saliva, and complete DNA were extracted from the can.

However, this was left behind intentionally by the murderer.

A kind of provocation. The murderer is a man who has never had a criminal record. He also believes that even if he leaves fingerprints and DNA, the police will not be able to find him.

Definitely a psychopath.

Only this type of person will seek the excitement after committing a crime through escalation again and again.

The rusty hammer, the torn off stockings...these iconic criminal methods seem to be the murderer emphasizing - it's me, I am the stocking killer.

I also left my DNA behind. Can you find me?

This time the police deployed an unprecedented number of manpower. They searched for hundreds of suspects and extracted DNA from each suspect, but still found nothing.

This serial killer seems to be hiding in the shadows.

The police set up a task force and continued to expand the search targets, but still had no clue.

And this murderer suddenly stopped committing crimes after committing his fourth murder in mid-June 2002.

As if the world disappeared, there has been no more "Stockings Murder" since then.

Is he dead? What happened?

The police then asked a psychologist for help. The psychologist believed that the murderer must have stopped committing crimes due to some changes, such as an accident, marriage, having a child, or entering another living environment.

These four unsolved cases have been hanging around like this for 20 years. The police officers who initially investigated the cases changed from young people to middle-aged people, and some old police officers retired after the investigation, but they were unable to solve these four cases.

Every policeman was filled with rage and gritted his teeth - he must catch this man.

But just can't catch it, time passes like this.

Fast forward 20 years, in 2022, the poor mother and daughter Chen Yanzhen and Chen Meng, one died and the other was injured.

The "Stockings Killer" appears again and lays down a fifth, more brutal murder.
