Solving the case is a little bitter, but my sister is super sweet

2016, April 1.

Beijing, Yanqing District Criminal Investigation Brigade.

meeting room.

The captain, instructor, deputy captain, squadron leader...all were present.

A police induction ceremony is underway.

Four trainee police officers, including Lin Xuan, were standing in front of the police flag to take the oath.

After rebirth.

See those familiar faces again.

Lin Xuan's heart was still uncontrollably excited.

The police induction ceremony is over.

Without any surprise, Lin Xuan met the master.

Zhao Qiang, a third-level police inspector with nine years of police experience.

Tall stature, broad shoulders, straight waist, as strong as a stone monument.

The weather-beaten wrinkles on the square face look like knife carvings.

In the previous life, it was Zhao Qiang who took Lin Xuan for a whole year.

He is a true leader who brings him into the field of criminal investigation.

He is also a qualified master!

noon.

Criminal Investigation Brigade backyard

"Master, smoke." Lin Xuan handed over the cigarette.

Zhao Qiang smiled.

He took the cigarette humbly and asked Lin Xuan to light it for him.

He took a breath and was slightly stunned.

Isn't this cigarette too good to smoke?

After taking a closer look at the cigarette in his hand, his pupils suddenly contracted.

There are not only some codes on the filter, but also anti-counterfeiting?

The strangest thing was that he glanced at the cigarette case in his apprentice's hand.

There is no brand, just some exquisite patterns, very high-end.

"What cigarette?" Zhao Qiang was confused.

"Someone gave it to me. I don't know what kind of cigarette it is."

Lin Xuan smiled and put the cigarette case in his master's hand.

This guy is too sensible... Zhao Qiang was surprised.

But just because his apprentice was sensible, he was also very happy.

The most fearful thing about taking a disciple is to take on some rigid and clumsy young people.

Not only is it tiring, but it is also easy to make mistakes, which makes the master very angry.

"Why do you want to be a police officer?"

Zhao Qiang asked with a smile while smoking a cigarette.

"Dream."

Lin Xuan smiled from the bottom of his heart.

"good."

Zhao Qiang put away his cigarette and said, "Let's go, I'll take you to have a long experience."

These words made Lin Xuan a little stunned.

To gain knowledge, I want to take him to learn how to investigate cases.

When he first joined the police in his previous life, he and his master were very idle.

The shocking kidnapping occurred three days later.

But it had nothing to do with Lin Xuan at that time, he was just a trainee police officer.

It wasn't until he became a full-time employee a year later that Lin Xuan really came into contact with investigations.

Now the kidnapping case has been solved by him.

If I remember correctly, there are no cases in the criminal investigation brigade these days.

What else does Zhao Qiang want to take him to investigate?

Is it the butterfly effect? ​​Lin Xuan looked solemn.

His rebirth seemed to have changed a lot of things.

The kidnapping case was solved and she had two sisters.

Special cigarettes that I have never seen before.

Now you can smoke it casually.

Even my father knows this cigarette.

Mom seems to know this kind of cigarette too.

Then, in front of him, Zhao Qiang actually wanted to take him to investigate the case.

Too many things have become different from the previous life!

…

Criminal Investigation Brigade, office area.

Zhao Qiang led Lin Xuan to a desk.

Turn on a computer and enter your personal password after turning it on.

He entered the internal system again and retrieved a case file.

Lin Xuan glanced at the file and was stunned for a moment.

Criminal investigation files.

Case name: Massive homicide

Case number: 1012289…

Suspect’s name: None yet

Time of filing: March 27, 2016

Case closing time:…

File filing unit: Criminal Investigation Detachment of Xicheng Branch

Filer: Special Investigation Team

…

The reason why Lin Xuan was stunned.

It's because this case is handled by a criminal investigation detachment in Beijing.

And the case happened four days ago.

Logically speaking, this file is unlikely to appear in their criminal investigation team.

Every extremely serious case will be investigated by a special task force.

The files will not be leaked.

When this happens, it can only explain one problem.

The case is classified as a difficult case, and there are currently no clues and cannot be solved.

Therefore, major units within the public security system were dispatched to assist in the investigation of the case.

Zhao Qiang was able to check the file, indicating that the case was assigned to him.

Cooperation among all units does not mean that all personnel in the unit must participate.

The truth lies here as well.

Everyone will take care of your case, but you don’t have to take care of the cases of other units?

Therefore, each unit will allocate several people to participate and assist.

"The detachment just sent down the case yesterday. Please take a look."

Zhao Qiang pointed to the file and said to Lin Xuan, "Study."

Lin Xuan nodded.

After sitting down, click on the file.

…

March 27, 2016, noon.

The Beijing 110 police station received the alarm call.

The reporter claimed to be the landlord of a daily rental house and went to the apartment for inspection at noon.

As a result, after entering the daily rental house, he witnessed a horrific murder.

At the time of the crime.

The reporter first came to the daily rental house and knocked on the door.

I'm sure no one answered, and I feel like the tenant has left.

Then he opened the door and walked inside to prepare for cleaning.

Unexpectedly, as soon as he walked into the living room, he was immediately scared to death.

A body lay on the living room floor.

There were patches of blood everywhere on the ground around the body.

What horrified the reporter was that the deceased's eyes were huge.

Chest and abdomen, all red.

Faced with this scene, the reporter was so scared that he collapsed on the ground.

After coming to his senses, he got up and ran out of the apartment.

Call the police...

The police station immediately dispatched nearby police forces to the scene.

The criminal police found out after they arrived.

There was not only one body in the daily rental house.

There were two more bodies in the bedroom.

Through facial comparison, the personal information of the three deceased was retrieved.

The deceased were a family of three.

A middle-aged couple and their son.

They were registered in other provinces and cities, not from Beijing.

Through the forensic on-site inspection, the cause of death of the three deceased was stabbing with a sharp weapon.

To further investigate, an autopsy is needed.

But it can be determined that the case is a homicide.

After the body was taken away, the police immediately set up a special task force.

The Criminal Investigation Brigade of the Xicheng Branch was in charge.

Through on-site inspection, investigators found that the murderer had a strong anti-reconnaissance ability.

There were no footprints, fingerprints or other traces left at the scene.

The murder weapon and tools involved in the case were not found.

The police began to visit and retrieve the surveillance of the apartment where the incident occurred, as well as the surveillance of the community.

To no avail...

Five hours later, the forensic doctor gave the preliminary autopsy results.

The victim was stabbed to death by a knife, and the murderer was skilled and professional.

The cause of death of the victim was that the knife pierced through the heart from the chest.

All three victims were killed by one knife!

Through the autopsy, the forensic doctor found that the three victims did not struggle at all when they were killed.

Through blood tests, the forensic doctor found... midazolam in the bodies of the three victims.

Midazolam: a sedative and sleeping drug.

It can cause human coma and sleep after taking it.

Then the forensic doctor extracted midazolam from the mineral water and fast food boxes at the scene of the crime.

It was determined that the three victims had consumed water and food containing midazolam before they were killed.

Through various signs,

This is a carefully planned mass murder!
