"This photo has been filtered, but I have found the filter of the corresponding color through photo processing technology, and I have removed the filter."

"On the train carriage in the photo, the train number of the train is indicated, I checked the train timetable of this train, and found that when this train arrived in Ningzhou City, it was in the afternoon."

"I determined the time, the angle of the sun and the direction of the sun, and the line of defense where the train was traveling. It can be accurately judged that the angle of this photo was taken from south to north. ”

"On the other side of the train, there is a row of tall buildings, which means that there are residential areas on both sides of the train road."

"I searched all the way along the railway line and found seven matching locations."

"According to the markers of the opposite building in the photo, finally! I've locked down where the photo was taken! ”

In the office of the Technical Investigation Section, Xiao Xuan talked and gestured at the computer, and kept telling me about his "great achievements".

"Hurry up!" I stood behind him and said angrily.

"The location is on the Northern Ring Road of Ningzhou City!" Xiao Xuan said to me very excitedly.

He looked at me with a great sense of accomplishment, his eyes full of expectations for me, as if waiting for me to compliment him.

I nodded, patted him on the shoulder, and gave a very honest assessment: "Good job." ”

"Gone?" Xiao Xuan raised his eyebrows slightly, and continued to look forward to my compliment.

"What more do you want?" I looked at him earnestly.

"I've worked so hard, can't you praise me more?" Xiao Xuan looked at me with a smile.

"Aren't these all pediatric for great hackers? I'm still busy, so I'll treat you to dinner another day. ”

With that, I turned around and left the Technical Investigation Division.

Walking into the office of the serious crime team, I said with some excitement: "The location of Zhang Jinghan and Su Yuxin's tryst has been found, and it is on the North Ring Road in Ningzhou City, near the railway line, so let's start investigating immediately." ”

After that, I made another phone call to Officer Wang and asked them to immediately lead the team to the North Ring Road in Ningzhou City to meet us.

Now that Zhang Jinghan and Su Yuxin's residence is locked, if Liu Aorong's dream is true, then Zhang Jinghan's burial place must be nearby.

The Crime Unit and the Criminal Police Team immediately set off and rushed to the Northern Link from two different locations.

Xiao Xuan has tried his best to narrow down the scope to one location through photos, and now, we only need to take the photos and lock the exact location of the shooting location according to the environment of the scene.

There are also some detailed markers in the photo, such as street lights, such as trees, such as grass on the side of the railway, such as a flower pot on the ground.

This kind of work, for experienced criminal police, can be described as handy.

Together I searched along the North Ring Railway Line in Ningzhou City, and soon found a residential building on the side of the road.

The railway line here has a very high track base, and the first floor needs to be looked up, and the third floor needs to be looked down. The shooting angle in the photo is basically at eye level, so the shooting location should be on the second floor.

And there is only one on the second floor that fits the shooting location, just behind us.

It is an old residential building, only four floors, and it looks dilapidated, the first floor has no residents, and the windows are sealed with bricks.

We immediately walked into the residential building and found that there were two residents on the second floor, but according to the layout of the house, the location where the photo was taken should be the one on our left.

"Knock knock." I reached out and knocked on the door, and behind me were members of the Serious Crime Team and Officer Wang.

No one opened the door for a long time, I put my ear to the door and listened carefully, the room was very quiet, there was no sound at all.

"Knock knock!" I knocked harder at the door again.

"No one."

I said helplessly.

When everyone heard the news, they all sighed heavily, just as everyone was thinking about their next move.

Jiang Tingbai, who was beside him, suddenly said in a deep voice: "Break the door." ”

"Breaking the door?!" All of us had our eyes on him.

I frowned even more, and asked seriously: "You want to break the door?" ”

Jiang Tingbai's expression was very serious at this time, he nodded to us seriously, and said, "Break the door, because I smell blood." ”

"The smell of blood? Why didn't I smell anything? Li Meng beside him sniffed hard, but there was no smell.

Everyone also sniffed it carefully, and they all said that they didn't smell any blood.

"Are you sure?" I looked at this Jiang Tingbai seriously, and asked in a deep voice.

We all believe in Jiang Tingbai, because he has eagle-like eyes and a dog-like nose, otherwise we wouldn't call him an old dog.

"I'm sure." Jiang Tingbai said in a deep voice.

His expression was very serious, which also proved that he was confident at this time.

Officer Wang beckoned, and the technical team behind him stepped forward, ready to open the lock.

After about a minute, the door slowly opened with the sound of a lock turning.

I don't know if it's a psychological effect, the moment we open the door, we do smell a faint smell of blood, but if we smell it carefully, we can't smell anything.

This is a relatively old residential building, and the layout of the house is also very retro, with two bedrooms and one living room, kitchen and bathroom.

The technical team first entered the scene for investigation, this is likely to be the place where Zhang Jinghan and Su Yuxin had a tryst, if there is really a smell of blood here, then there is a high probability that there has been a homicide here, and it is also the scene of the first crime.

But we didn't find a lot of blood, at least not now.

Directly in front of us is the living room, and the window facing the living room is direct.

The members of our serious crime team also put on disposable gloves, shoe covers and other equipment for the investigation of the scene, and walked into the living room.

Standing in front of the window of the living room, it was the railway line outside.

I picked up the photo in my hand and carefully compared it with the scenery in front of me, and it was exactly the same.

Now it can be determined that this photo was taken by Zhang Jinghan standing in front of the window.

Moreover, Zhang Jinghan used to stand in my position.

The technical team is carrying out a comprehensive survey of the site, and all kinds of survey instruments are also on the battlefield. Especially Jiang Tingbai, he believes in his nose very much, holds a biological sample discovery device in his hand, and is tracking blood stains in a carpet style.

As long as there have been blood stains here, no matter how the blood stains are cleaned, they will still leave blood stains.

"It seems that Zhang Jinghan had a tryst with Su Yuxin here." Lin Zifan said slowly.

"That's right, there is no dust in the house, which means that it must have been inhabited for a long time." I reached out and wiped it on the windowsill, and there was no noticeable dust left on my fingertips.

Li Meng went into the bathroom to check, where she found two sets of toiletries, and one of them was obviously something that only women would use.

Unless, there are men who live as delicately as women.

"Team King! Bedroom has a discovery! ”

After a while, the voices of members of the technical team came from the bedroom on the right.

We hurried into the bedroom together.

In front of me, there is a wardrobe with an open door, but this cabinet door has just been opened by the technical team.

In addition to a small amount of clothing, there is also a quilt.

And on the bed where the quilt should have appeared, there was nothing.

The technical team gently opened the quilt, which was covered in blood......
