Xiao Q is a new type of drug at present, although it is not included in the list of D products in China, but it also has the same harm as D.

Long-term chronic hypoxia in the brain can lead to memory loss, depressed mood, apathy, and even dementia. Heavy smoking can cause hallucinations, induce mental illness, and for people who already have some underlying medical conditions, it may also induce epilepsy and arrhythmia.

In severe cases, it can lead to vitamin B12 deficiency, which in turn leads to neurological diseases, which is the most common and most harmful symptom. Patients mainly present with numbness of the lower limbs, unsteady gait, muscle atrophy and even paralysis of the limbs.

Regardless of whether the people in room 332 are smoking laughing Q or not, we must investigate deeply.

After getting the key card from the owner of the Kimbo Hotel, we came to the door of room 332 together.

"Open the door! Police routine check! Gong Haonan knocked on the door and shouted.

As he spoke, all of us put on gas masks to prevent the intake of toxic gases.

No one spoke for a long time, Gong Haonan held the police weapon in one hand, opened the door with the room card in the other, and rushed into the house in an instant.

It was a big room, the room was very messy, and as soon as we entered the door, we saw three young men, none of whom looked very old, all of them were about twenty years old.

Two of the men were lying on the bed and one man was lying on the ground, motionless.

The room was littered with garbage, a silver-white cylinder on the bedside table, and several balloons scattered on the bed.

Both windows in the room are open, the air circulation reduces the concentration of toxic gases, and the room is safe.

We took off our gas masks and immediately went to check the vital signs of the three men.

We were still late, and all three men had stopped breathing and their hearts were dead.

Gong Haonan looked at the appearance in front of him, shook his head slowly, and said seriously: "Notify the technical team to come over to investigate the scene, and let the forensic doctor come over for an autopsy." ”

From the clues we have and the situation in the room, the cause of their death is the same as that of the boy in the hospital, which is caused by inhaling toxic gases.

And the silver-white steel cylinder on the bedside table should be the culprit.

But now that a fatality had occurred, we didn't rush into the scene of the crime, but were prepared to wait for the technical team to arrive.

After the windows were opened and ventilated in the room, there was no longer any strange smell, and the toxic gases had basically disappeared.

The two anti-narcotics policemen next to him looked at the situation in the room, and finally fell on the silver-white cylinder at the head of the bed.

"This container should be for laughing Q, we have seized many cases of gathering crowds to smoke laughing Q before, all of them are this kind of cylinders, but there are various colors of spray paint. And the balloons scattered on the bed are also smoking tools. As for why they sucked themselves to death by sucking Xiao Q, the gas in that cylinder had to be checked. The anti-narcotics police said in a deep voice.

About fifteen minutes later, the technical team and forensic doctors had already arrived at the scene and started the on-site investigation work.

"What about Xue Hang and Zifan?" I asked.

"They are still investigating the situation in the hospital, I came with the technical team, how is it? Did you find anything on the spot? Jiang Tingbai walked quickly to my side and asked.

I shrugged my shoulders a little helplessly, didn't speak, and gave him a look.

Jiang Tingbai walked up to my side and looked into the room.

"Three people...... Jiang Tingbai gasped directly and frowned.

"Sucking Q sucking to death?" Jiang Tingbai looked at me and Li Meng in a daze, and asked weakly.

"Dead is dead, it's not clear how you died, but it's mostly because of Xiao Q, maybe something has been added to this Xiao Q......" Li Meng said lightly.

Li Meng's words reminded me of the cause of Agen's death.

Anyway, Xiao Q is also a kind of D product, and the three teenagers died because of drugs, will it have anything to do with the large number of D products that have appeared on the market recently?

Maybe someone used a cylinder with another type of gas with D to get into the laughing Q......

"I seem to know why there are so many D products on the market lately." Thinking of this, I suddenly muttered.

"You mean, the number of D products on the market has not actually increased, but someone has appeared on the market with toxic substances packaged in the appearance of D products?" Li Meng looked at me and suddenly said.

I nodded and continued, "If that's the case, then in the near future, there will be a lot of D-sucking deaths. ”

"Who would do that? D-Group? There's no reason for that! Jiang Tingbai shook his head a little puzzled, and said in a deep voice.

This question is the crux of this case.

I opened my mouth and said, "Group D is engaged in the business of D products, and only when there are buyers can they make money." If they poison the D product, then the buyers are dead and their business is gone. So there must be a second force in Renxi City, but what is the purpose of this second force? ”

"Will it be black and black again, this second force is also a D-making group. In this way, they used the local D-making group to be discredited, and then the second force took the opportunity to take the position? Li Meng followed my thoughts and continued to analyze.

I still shook my head, and I always felt that there were a lot of doubts in this.

"If the second force is also a D-selling group, it is completely possible to destroy their reputation with fake and shoddy D products. But the second force is poisoning. They poisoned all the D-sucking personnel, so what can they do even if they are in the position? There's no market anymore. I frowned, unable to think of a reasonable explanation.

But no matter what we guess, everything will be clear as soon as the technical team examines the gas composition in the silver-white cylinder.

After a preliminary autopsy at the scene, the medical examiner has determined the cause of death of the three deceased, all of whom died of suffocation due to respiratory failure caused by inhalation of harmful gases.

It seems to have the same symptoms as the boy in the hospital.

Now that I think about it, the boy in the hospital really had a big life, and it was precisely because he restrained his curiosity and did not participate in smoking that he picked up a life.

Self-control is such an important ability that can even save one's own life.

Now that the forensic doctor has determined the cause of death, the nature of this murder is clear, and the on-site investigation of the technical team must not have found any important clues.

However, this does not stop the on-site investigation, and some information about the source of the toxic gas bottle may be found at the scene.

"How do I smell a rotten apple?"

We were about to leave with the forensic department, when Jiang Tingbai suddenly muttered.
