Solving a Case: I Beg You, Get Out of Prison!

"However, as you said, then we still have no way to find any clues and evidence. The murderer had left before the incident. He will definitely take away everything from the scene of the crime and will not keep it. Any traces."

Although Zhao Yang admires Song Ye's thoughts at this moment, in his heart, Song Ye's thoughts are still not substantively helpful and have no effect on the progress of this case.

But at the moment.

Song Ye gave a deep smile.

"Who said that no evidence will be left at the scene of the crime?"

"I ask you, when you arrived at the crime scene, whether it was the money-rich crime scene or Qian Ruilong's crime scene, did you find that the doors and windows were closed and there was no ventilation after you entered?"

Song Ye asked Zhao Yang.

After Zhao Yang heard the words, he nodded and said after thinking for a moment.

"It is true, and it is precisely because of this that this case is judged to be a murder in a secret room." Zhao Yang said in a daze.

"That's right. This environment is exactly what the murderer needs. Only when the doors and windows are closed can the effect of the medicine be brought into full play, and because of the volatile substances, the crime scene can be free of any medicine. Residue."

Song Ye immediately chased after him.

Zhao Yang also suddenly realized at this moment.

Because the current situation is just like what Song Ye said, if it is really caused by the use of Pusipu agent, then it must be an environment with closed doors and windows and no ventilation. Only in this environment can this be done. The medicinal effect of the medicament is exerted to the extreme, and with their precise medicament control, there is no trace left after the victim is killed.

"It is precisely because of this that the device used at the time of the murder is definitely still at the scene of the crime, but what you were looking for before was not these things, so you did not notice that the words and objects may look very ordinary and unremarkable."

Song Ye also said slowly.

Although Song Ye didn't know what the device was needed for this murder, Song Ye knew in his heart that this was at least something that could make the Pusipu agent emit.

Whether it is a spray type or other forms, it will definitely leave a corresponding evidence.

After Song Ye finished speaking, Zhao Yang did not speak out, but fell into contemplation. After all, the amount of information that Song Ye revealed at this moment was too large, and Zhao Yang had to digest it for a while.

Zhao Yang thought about it for a long time.

Only then did he speak slowly.

"Then I will now quickly look for Qian Ruilong's crime scene to see if there are any killing devices like you said."

Although they don't know what the killing device is, but now they have such a thought and idea, it can be easier to find, and it is not as clueless as before.

After speaking, Zhao Yang began to look for Qian Ruilong's crime scene.

Because Qian Ruilong died in the hotel suite bedroom.

The space is narrower and extremely closed. In addition to this suite, there are not many things matched by the hotel itself in the bedroom, so it can be well screened out.

Zhao Yang called Li Hua over.

Li Hua is the manager of the hotel, so he naturally knows the configuration of the items in the luxury suites in this hotel.

As long as you can find items that are not the hotel configuration from this hotel suite, you will be able to find what Song Ye said at this time. Zhao Yang also knew this well and brought Li Hua to start searching.

They first started searching in the bedroom at the scene of the crime.

"Manager Li, there are quite a few things in your suite?"

As Zhao Yang searched, he also sighed inwardly, this hotel suite is indeed a bit luxurious.

No matter what you can use or what you don't need, they all appear in this hotel suite.

Li Hua smiled faintly at this moment.

"After all, I have charged so much room fees from customers. Whether it is environmental treatment or hotel related configuration, it must be complete, otherwise it will become a scam."

Li Hua did not forget to add some brilliance to his hotel at this moment.

However, Zhao Yang stopped in front of the bedside table at this time, and his eyes were fixed on an item on the bedside table.

"Manager Li, is this aromatherapy also available in your hotel?"

Zhao Yang clearly saw a very delicate package of fragrance on the bedside table, but there was really no fragrance in the fragrance.

Zhao Yang's remarks also made Li Hua a little embarrassed.

Li Hua rushed to Zhao Yang's front and looked at the fragrance in front of him.

"Our hotel suites do have aromatherapy configuration, but this thing is not our hotel, perhaps it was brought by the customer, it shouldn't be any evidence of murder."

Li Hua recognized at a glance that the fragrance on the bedside table was not the official configuration of their hotel.

But it's just a fragrance, and it can't explain anything. It's impossible to kill people because of this fragrance.

Zhao Yang's expression was solemn.

Then I took this fragrance with white gloves and took it in my hand and looked at it carefully.

It was even closer to the mouth of this fragrance bottle and smelled it.

But after smelling it, Zhao Yang frowned, because he smelled alcohol in the aromatherapy bottle at this moment.

Although the smell of alcohol is not strong, but with Zhao Yang so close, it is enough to smell the smell of alcohol.

"No, this thing is likely to be evidence of murder."

Zhao Yang said at this moment, and then picked up the fragrance and put it in a plastic bag.

Because now Zhao Yang doesn't know if this fragrance is the killing device Song Ye said, but judging from the way the fragrance is used, it's quite possible.

After all, aromatherapy itself relies on the fragrance emitted by volatilization to remove the peculiar smell in the room and increase the fragrance.

If this aromatherapy is discharged here for too long, if it is really the Pusipu agent plus alcohol that Song Ye infers, then the medicinal effect exuded at such a time can definitely cause fainting and suffocation.

And because the bottle contains alcohol, the rate of volatilization will also increase. As of this time, there is nothing left in this bottle.

After finding the aromatherapy bottle and sealing it up, Zhao Yang took it to the door of the suite.

"Hurry up and send this thing back to the Appraisal Division for appraisal, what kind of substance it is here."

Zhao Yang said sharply.

However, Zhao Yang's remarks really puzzled the captain of this branch.

"This is not just an aromatherapy. Team Zhao doesn't need to make such a fuss. If everything in this room is sent to the technical department for testing, it will definitely affect the progress of the case detection."
