Legal program "Skynet" case: the girl was brutally murdered, who pushed open her door

In 2014, a vicious rape and murder occurred in Hengyang, Hunan.

After the police pushed open the door, they saw a triangular object wrapped in a blanket, and when they opened it, it looked like a female corpse.

The woman's posture shocked the police at the scene, pantyhose were faded to the ankles, the lower body was naked, the feet were tied by several shoelaces, the hands were tied behind the wires, and the mouth was sealed by tape.

First, who opened her door

Bai Xue (the victim's pseudonym) is a migrant worker who lives alone in the small house he rents.

On the afternoon of April 19, 2014, she went home from work → shopping → as usual.

But after returning to the rental house, she never came out again.

It wasn't until two days later, when the police received a report, that they opened the door of Bai Xue's room again, and the opening scene appeared inside.

After preliminary judgment, this is a vicious homicide, the cause of death of the deceased is mechanical asphyxiation, and the murder weapon should be the hair dryer wire scattered on the ground.

There were many scars on the body of the deceased, and there were very obvious strangulation marks where the hands and feet were tied.

The police judged that the deceased had a fierce struggle before his death, should have been brutally ravaged, and should have been violated by the murderer.

Then the forensic doctors also made a major discovery, they found semen spots in the body of the deceased, which not only confirmed that this was a rape and murder case, but also a major clue, the killer's DNA was available, so that it was easier to find the murderer.

However, here to give you a little science, the collected DNA of the murderer is not the same as finding the murderer, the DNA of ordinary people will not be recorded, only those who have had a criminal record will be left with DNA information.

Second, how did the murderer open the door?

The police carefully inspected the scene, and there was no sign of damage to the door.

Then the murderer entered the house after a few ways:

1. Follow the snow and wait for her to open the door herself and take the opportunity to enter.
2. Technical unlocking.
3. Knocking on the door, Snow himself opened the door for the murderer.
4. The murderer had the key to the room.

The police took the lead in analyzing the first possibility, because the items purchased by Bai Xue on that day were intact in the room, and the habit of the building occupants would not put things away before closing the door.

The killers could only force their way in before the snow closed the door, so that the daily necessities would be spilled on the ground, but the police found that the tomatoes purchased by the snow that day were intact on the table.

The possibility that the police knew to be trailing snow could be ruled out.

However, the author personally believes that if the murderer prepares eggs and tomatoes in advance, and then forcibly enters, and when the crime is over and leaves the scene, he puts the items he prepared at the scene, can he forge this evidence?

However, this may be relatively small.

Snow buys tomatoes

Technical unlocking was directly excluded because professionals inspected the lock cylinder of the door and no signs of friction were found.

The remaining two methods of entering the house are the most likely, either the murderer knows Snow, can let Snow open the door by himself, and can also enter the room.

Either the murderer has the key to the room, which is related to the house, and can enter the room by opening the door with the key.

The police first asked, and the first person to find the deceased and call the police was the landlord Wu.

Wu said that someone told him that a strange smell came from the house rented by Bai Xue, which made him ask clearly, but he could not contact Bai Xue himself.

Out of desperation, he opened the door to check, and as soon as he opened the door, the smell became even heavier, and then he saw an unknown object wrapped in a blanket.

Thinking of the strange smell in the house, the landlord directly called the police.

Wu mou is by renting a house to make money, and the conditions are good, he should not kill people in the house he still wants to rent, Wu mou is not suspicious.

The house was converted by the landlord into five separate studios and rented out to five different people.

The medical examiner had determined that Snow's death was around 8 p.m. to 10 p.m. that night.

Police conducted interviews with other tenants, two of whom were in the room during this time.

One of the families was a college student, he was busy preparing for the graduate school, in order to concentrate on studying, he closed the doors and windows very strictly, and wore headphones to study seriously, and did not hear anything that day.

The other family was a couple, their doors and windows were also very tightly closed, and the two were watching TV with their arms around each other, watching more attentively and not paying attention to the movement outside.

The landlord, the college student, and the man all had DNA tests, unlike what the killer had left behind.

Although they live under the same roof, they not only know each other, but they have not even spoken a few words, which is also a normal situation now.

Until now, the police have no clear clues in their hands other than the DNA of the murderer.

In the end, the police decided to start with the surveillance video, but there are many rental houses in the place where Bai Xue lives, and the flow of people is very large, even if there is surveillance, it is very difficult to investigate.

Such a 19-year-old flower girl was so brutally killed, and the police officers were also very anxious.

Third, the boyfriend said, someone wants to make Bai Xue a small three?

Meanwhile, another group of officers investigates the interpersonal relationships of the deceased during his lifetime.

Bai Xue was a salesman of a real estate company before his death, although the work time was not long, but colleagues remembered this beautiful 19-year-old girl.

Because her boyfriend Liu Wen also does sales here, the two developed very quickly, dating for about a month, and often commuting together.

And Bai Xue has a cheerful personality and a big grin, so colleagues often use Liu Wen to joke about Bai Xue, often making her make a big red face.

Liu Wen can go in and out of Bai Xue's house at will, but he doesn't seem to have any motive for committing the crime, and both colleagues say that they have a good relationship and have already lived together.

But with or without a motive, it's always okay to investigate, after all, the police have the DNA of the killer.

Liu Wen was summoned to the police station to investigate, and took blood samples for DNA testing, and the police learned from Liu Wen that there was a manager of the company named Jia Fang who often harassed Bai Xue, and Bai Xue complained to himself many times.

This Jia Fang attracted the attention of the police officers because he had a motive for committing the crime.

At this time, the test results also came out, and Liu Wen's DNA did not match Bai Xue's body.

Excluding Liu Wen, Jia Fang's suspicions are even greater.

Because he had pursued snow, but did not chase it, love and must not be the most prone to mistakes.

After investigation, the police found that Jia Fang has a family, and the husband and wife relationship is good, he should have no intention of divorce.

But in this case, Jia Fang went to provoke Bai Xue, which showed that his purpose was not pure, and relatively speaking, even if Bai Xue did not like him, if he knocked on the door, Bai Xue should also open the door.

Therefore, Jia Fang's suspicions are very large.

The police began to investigate, but it was clear that it was not Jia Fang.

Because during the baixue victimization period, Jia Fang accompanied his family to travel abroad, there is sufficient evidence of alibi, and Jia Fang can rule out the suspicion of committing the crime.

But in this case, the investigation of the case has fallen into a dead end, except for Liu Wen and Jia Fang, the others around Bai Xue have no motive for committing the crime.

4. Could the murderer be a former resident?

The case is deadlocked, and some police officers believe that if the acquaintance is excluded from committing the crime, then there is only one possibility, that is, the murderer has the key to the snow house.

But the tenants here are very complex, most of them are short-term rents, and some tenants leave in a month or two.

That is to say, the door key where Bai Xue lived passed through the hands of many people, and it is not excluded that the previous resident key was lost, picked up, and killed Bai Xue when he was burglarized.

The police began looking for former residents and agents with keys, taking their blood samples one by one for DNA testing.

However, DNA testing is very complicated, and many residents can no longer find it.

At this time, the police got an important clue that after Bai Xue's death, someone had used her bank card to withdraw cash twice.

Police locked the man in the picture in a raincoat.

According to the time of death judged by the forensic doctor, the first time the person withdrew money was shortly after Snow Snow's death, taking Snow's bank card to the ATM.

It didn't rain that day, but the suspect wore a raincoat the whole time and deliberately covered his face.

However, the suspect's electric car and the logo on the raincoat are very conspicuous.

The police investigated the nearby merchants selling this electric vehicle, but the electric vehicle did not carry out a real-name system, and the route photographed at that time was very vague, and the police did not find useful clues.

However, during the surveillance the next day, the police again found the figure of the man in the raincoat.

This time he took all the money from The Snow Card, and this time the suspect was wearing a raincoat.

When entering the bank, he deliberately pulled down his raincoat to try to cover his face.

The police believe that the person wearing the raincoat is very likely the murderer of this case.

In 2014, although there were cameras everywhere as it is now, the local urban area was gridded.

There are also a large number of monitoring probes in each grid, especially at the main street entrance.

These monitors form a huge "sky net", the police according to the surveillance of the criminal suspect appeared in the picture, from the raincoat and electric car, to find out the time and route of the suspect after committing the crime, leaving the scene.

And found the suspect's trip to withdraw money twice, and the man wore a raincoat the whole time during the withdrawal process.

After determining that the weather was sunny and cloudy that day, the purpose of the suspect wearing a raincoat was clear at a glance.

The police along the route of the suspect riding an electric car to escape to investigate, in the previous surveillance screen, the suspect wearing a raincoat disappeared and did not appear again, corresponding to the next monitoring screen, there is an extra picture of a suspected criminal suspect who is not wearing a raincoat.

After comparison was the same electric car, and snow died that night.

Shortly after the suspect went to the bank to withdraw the money, the man also passed by the intersection.

Shortly after disappearing from the previous surveillance footage, the man appeared in the next surveillance footage.

In order to verify, the police rode an electric vehicle to test, from the time the last surveillance screen disappeared to the time required for the next surveillance screen to appear.

In the end, it was found that the time spent was a little less than the man in the picture, and this little point is likely to be the time when the suspect took off his raincoat.

According to surveillance footage, the man eventually entered a construction site.

After the police arrived at the construction site, they saw video surveillance cameras at the entrance of the construction site.

Police found the suspect's figure in video surveillance, based on the footage of him entering and leaving the construction site, plus his whereabouts in the "Skynet".

The police determined that the time of the suspect's action, departure and return were exactly the same.

However, there are nearly a thousand workers at this construction site, although there are surveillance footage, but the picture of 2014 is certainly not as clear as it is now, if you do not know, it is difficult to fully see who the person in the picture is.

Just as the officers were preparing to investigate one by one, good news came from the DNA laboratory.

Fifth, the murderer did not have any intersection with the white snow?

The person who matched the killer's DNA was found, that is, Zhou Jun, a resident before Bai Xue rented a house.

And Zhou Jun happened to be the workers in the construction site found by the police.

The police immediately arrested him.

Zhou Jun? A person who didn't know Bai Xuesu, how did he get into Bai Xue's room? And why did you kill the snow?

After being arrested, Zhou Jun directly confessed that he was able to enter Bai Xue's room because Bai Xue himself lacked safety awareness.

Because the house is a house in the old community, Bai Xue did not change the door lock after a girl moved in.

(Here to remind you, you can tell the people around you or children, if the rented house is an old-fashioned door lock, especially a girl living alone, try to communicate with the landlord to replace the door lock, the original lock cylinder can be saved, and then put the original lock cylinder back when you leave.) ）

And his killing of Snow White was indeed an impulse.

Zhou Jun said that he wanted to go back to the rental house to move his things after checking out, so the day before check-out, he secretly assigned a key, which was not handed over to the landlord.

But he is clearly lying here, how much luggage can a man who goes out to work have?

Can't you finish moving in one day, but also have to go a day in advance to match the key and move later?

Bai Xue had been living in it for a long time, and he returned to the rental house again, was it to carry his luggage?

Not long after Zhou Jun moved away, Bai Xue lived in this rental house, but she neglected not to change the door lock.

The 24th is Zhou Jun's 22nd birthday, and he wants to make his birthday better, but he is shy, so he has a crooked mind.

On the 19th, he took the key he had previously assigned, returned to the rental house again, and rummaged through the belongings inside.

It can be seen from here that Zhou Jun is not a good person, working outside even without money for his birthday, and he still wants to steal in order to have a good birthday.

Zhou Jun's own confession was that he was rummaging through his belongings in the room, and Bai Xue had returned, fearing that he was hiding behind the curtains.

When Bai Xue returned, he saw that his home was turned into a mess, and then found himself again, and he was afraid that she would call the police, so he tied up Bai Xue.

Then he said that he only needed a few hundred dollars, and he gave it and left, but Bai Xue kept saying no.

He then found the bank card from Bai Xue, forced him to reveal the secret, and prepared to leave.

But Bai Xue had been calling for help, he was afraid of being discovered, and he himself had said that as long as a few hundred pieces, Bai Xue began not to ask for help now, the more he thought about it, the more angry he became, out of revenge he returned to the room again and killed Bai Xue.

Is what the criminal says credible?

The case ended here, and it is not clear how Zhou Jun was punished, but presumably it will not be lightly punished, and the crimes of intentional homicide, robbery, and rape are enough to be shot.

So is what the criminals end up saying is credible?

Personally, I think he will definitely beautify himself, if he works at the construction site seriously, how can he not have money for his birthday, and send them all home?

It can be seen from this that Zhou Jun is a bad young man, who should have returned to the construction site after spending his own money, and his motive for secretly giving the key was bad.

Secondly, the first thing that came to mind when there was no money was to steal.

If he just wants to steal, why not steal during the day? Do you have to wait until you have to go home from work at night to steal?

Snow white a girl, if the robber really only needs a few hundred pieces, how can she not give, and it is in the case of being tied, if you really do not give the bank card password how did it come?

Moreover, Bai Xue had obvious signs of struggle before he died, and Zhou Jun invaded Bai Xue in one breath?

These are all doubts.

After killing people, they can calmly withdraw money, and there is no sense of guilt, not afraid at all?

It's not so much that he's angry and careless.

It is better to say that it has been planned for a long time, purposefully sneaking into the white snow room, the criminal is the criminal, but it is a pity that the snow girl is a flower girl.

Finally, it is emphasized that if it is a single girl renting a house, it is best to change the door lock, and in the case of finding that it is not right, run directly, run to a place with many people, any resistance means said on the Internet are useless, and the gap between men and women is really large.

If what Zhou Jun said was true, then when Bai Xue pushed open the door, he did not go in but turned around and ran, and this might not happen.
