"What did you say?!"

The captain of the criminal police looked at me seriously and affirmed, "That's right! When we came to inspect the site, it was definitely not like this in the room! The doors and drawers are absolutely not opened! By the way, there are photos in the dossier! ”

Hearing this, I quickly opened the file and took out the photos inside to check it. At this moment, I suddenly felt a chill down my spine, and the hairs on my whole body stood up......

The photo was taken by the criminal police who investigated the scene at that time, the angle was very professional, the image was particularly clear, and the entire room environment was included in the picture.

This also means that after the criminal police left the scene of the investigation, someone here came and rummaged through the room for something......

Could it be that the murderer is back?

Since this person came after the investigation of the scene, he will definitely leave traces at the scene, and now an urgent on-site investigation is needed.

It was already getting dark, and after the fire, the circuit in the Zhu family's house had been seriously damaged, and we had to rely on flashlights to investigate the scene. The captain of the criminal police proposed to transfer some people from the public security bureau, but I refused, this is far away from the public security bureau, and the police force is a little time-consuming, and the serious crime team is all there, the equipment is also there, and it is enough to investigate a house.

At present, the Zhu family's house is already a little dim, the line of sight is not good, and the layout of the house is not very familiar, and the wooden building has become extremely fragile after the fire.

Because of this Zhu family's murderous house, it is really weird.

As the visibility continued to decrease, I suddenly noticed a ghost fire flashing on the wall of the stairwell connecting to the second floor.

There were about a dozen of them, scattered on the walls, emitting a faint green light, which made my scalp tingle.

I slowly approached, reaching for the ghostfire, my finger against the rough wall.

Then, my fingers glowed green......

If you look closely, your fingertips are stained with something in the form of powder, which is a phosphor.

It turns out that the mural on the wall is covered with a thick layer of phosphor, and every night, the mural glows with a faint green light. It's just that after the fire brigade extinguishes the fire, a large amount of phosphor has been washed away, and only a few places remain, which are still glowing.

This writer is a pervert, isn't he?!

Engage in this kind of thing in the murderous house, why don't you build an altar here, and invite a pen fairy or something?!

I wiped my hands in disgust and continued to investigate the scene.

Jiang Tingbai took out an instrument called "Wide Range Light Measurement" from his backpack, which looked like a rubber mop, but it was the nemesis of dust footprints, even shallow footprints could be illuminated.

Lin Zifan is holding an instrument called "Biological Sample Discovery Instrument", which can be divided into ultraviolet light, blue light and white light according to different wavelengths, and can clearly find biological samples such as blood and saliva without adding fluorescents.

Xue Hang was carefully inspecting the windows and doors, observing the signs of destruction.

Li Meng found some damp clothes in the washing machine in the bathroom that had not had time to dry after cleaning, exuding a musty smell, she frowned, and muttered in disgust: "No one really uses underwear and socks in the washing machine......"

Soon, Jiang Tingbai found a very shallow footprint in front of the wardrobe and immediately carried out the footprint extraction work.

"Boom!"

At this moment, the empty Zhu family's murderous mansion suddenly made a muffled sound, and a huge sound echoed on the second floor.

In fact, this muffled sound is not too loud, but in such a quiet environment, the sound is so loud.

All of us immediately froze in place, held our breath, exchanged glances with each other, and carefully searched for the source of the sound.

Xue Hang looked up at the ceiling and waved his hand, the voice coming from overhead.

Above the second floor, is an attic.

Everyone slowed down, made no sound, and approached the staircase leading to the attic.

In front of me is a simple wooden staircase, about two meters high, very narrow and can only accommodate one person, and at the end of the staircase, there is an iron door.

Xue Hang gestured to us, signaling us not to move, and he went up to take a look himself.

He slowly lifted the hem of his trench coat, pulled out a police pistol from his waist, opened the safe, and slowly walked up the stairs.

The iron door was slammed open, and a man stood behind it.

"Don't move! The police! ”

Xue Hang pointed his gun at the man's eyebrows with both hands and warned sharply.

The man looked at the barrel of the black hole, froze for a second, and let out a piercing scream out of control.

There was a man hiding in the attic, which was already terrible enough, and this sudden scream made our hearts tighten.

"Squat! Hold your head! Xue Hang's eyes were fixed on the man, his index finger on the trigger, and he shouted sharply.

The man was so frightened that he immediately crouched down and held his head in his hands.

He had just crouched down, and behind him, we saw another man.

"Squat! Hold your head! Xue Hang raised his arm slightly, and the pitch-black muzzle was aimed at him.

The man behind him was weak under his feet, and he knelt directly on the ground with a pop.

Behind him, we saw another woman......

"You! Get down! Hold your head! ”

The scene was chaotic for a while, and it was as if we were watching a magic show that changed people, and the three of them hid in the attic and stood in a row, crouching down one by one.

Fortunately, they did not resist, and under Xue Hang's gun, they obediently walked out of the attic, handcuffed them respectively, and squatted in a row in the corner of the wall.

Xue Hang unloaded the bullet with great skill, closed the safe, and put the pistol back into the holster on his waist.

"What are you guys doing?!"

The Serious Crime Team stood in a row in front of the three people, and the light of the flashlight hit the three people in the face.

The woman who was squatting in the middle was so frightened that she sat on the ground and cried out.

"We, we're students!" The man beside him said in a trembling voice.

I dug through three student IDs in the pockets of all three of them, all sophomores at a nearby high school.

"You three, what are you doing here?" I asked sharply, in an emotionless tone.

"We ...... Let's investigate and solve the case......" One of them stole a glance at me and said weakly.

What? These three little kids are here to investigate and solve the case?!

After careful questioning, I learned that the three of them are fanatical fans of detective mystery novels, and the three of them spontaneously formed an organization called the "Young Detective Group", and heard that there was a murder in a locked room here, and the three of them were ready to come here to investigate. They deliberately waited for the police to finish investigating the scene before coming, for fear that the footprints they left would interfere with the police to solve the case.

"The Junior Detectives? Conan has seen too much. Li Meng shook his head, he really couldn't figure out what young people think now.

"What did you guys do here?" I crouched down and asked helplessly.

"As soon as we came in, we heard someone coming, and hurriedly hid in the attic." The girl sobbed a few times and spoke aggrievedly, as if we had interfered with their investigation today.

"Did you turn through the wardrobes and drawers in the house?" I stared at the three of them and asked earnestly.

After hearing this, they shook their heads together and denied it: "We really just came in and didn't move anything, and it was the same last night." ”

"Last night? You guys were here last night?! I was stunned and immediately asked.

"Last Night......

The girl's voice trembled a little, and her tearful eyes showed a frightened look: "Last night, we met a ghost here, and we heard the ghost singing......"
