"These three people were originally here to have fun, why did they commit suicide?" Qiao Yifan frowned, "And there are no tools to commit the crime at the scene, could it be that they died by holding their breath?" Besides, those three singing girls don't know each other, okay, why did they pull them to accompany them to the funeral?"

"Judging from their posture after they died, no one came to ask these six people to do anything at that time, although the scene was chaotic, but it was very common-sense, and there was nothing abnormal!" Qiao Yifan continued, "Moreover, the surveillance shows that since the waiter who delivered the red wine left, two of the three guests have also appeared in the surveillance, and one of them also hung a "Do Not Disturb" sign outside, which means that they were still alive at that time!"

"The reason why they hung that card is probably because they want to flirt with Miss inside!" Qiao Yifan added. Pen "Fun" Pavilion www.biquge.info

"Didn't you find anything else?" Wen Jing also interjected.

"No!" Qiao Yifan scratched his head helplessly.

"Didn't you notice the smell of wine in that ice bucket?" I finally reminded him.

"This is also normal, many guests like to pour wine into the ice bucket when they can't drink, and some people even use it to avoid drinking!" Qiao Yifan was not surprised when I asked.

"Actually, the problem is with the ice bucket!" I smiled faintly.

"It looks like you've gained something!" Qiao Yifan immediately laughed because he saw me laughing. "Don't sell it, hurry up and listen to it!"

"Actually, I didn't pay attention to it until the strong smell of wine in the ice bucket stimulated me, and I looked more closely. ”

When the three of them saw that I was confident, they all looked at me with anticipation.

"There are a lot of suspicions about this ice bucket, first, until we arrived at the scene, all the ice in the ice bucket has not completely melted, second, there is too little water in the ice bucket, and third, as I just said, there is a strong smell of liquor in it, and it is the smell of high liquor!" I touched another cigarette and lit it.

Before he had time to put away the cigarette, he was snatched by Hong Kaiyuan: "The old smokes alone, and I pick the door and get home!"

"The ice water mixture is usually zero degrees and has a long storage time, which is normal!?" Qiao Yifan was still puzzled.

"But it's August, and the temperature is still high. I replied unhurriedly, "It's been almost nine hours since the incident, and I just paid special attention to it, the temperature of the air conditioner in the room is twenty-two degrees, and that little bit of ice-water mixture can last so long?"

"Then what do you say about the second point?" Qiao Yifan did not give up.

"It seems that Team Joe hasn't been to these occasions much!" I sighed, "In a place like this, they will fill a lot of water in the ice bucket and add an appropriate amount of ice to achieve the effect of freezing the drink, and it will not be wasted! Add at least half a bucket of water, then add about a quarter of the ice cubes, and finally put in the drink! This is not the case at the scene, the water is just at the bottom, and the wine bottles are almost always standing at the bottom of the barrel, which is contrary to common sense!"

"This should be inconclusive, right? More and less varies from person to person and from place to place, right?" Hong Kaiyuan couldn't help but say.

"Of course, there's no standard for measuring this, but if you want to have a cold drink, at least you can soak the bottle," I asked rhetorically. The three of them immediately understood.

"On the last point, as you said, the guests poured the wine they didn't want to drink into the ice buckets, but I didn't see any liquor bottles at the scene, they were all beer! "It's not like the waiter has nothing to do with the water to mix liquor into the water, right?"

"What does this mean?" Qiao Yifan was still confused.

"You didn't pay attention to the detail I just asked the waiter who delivered the wine!" I sighed helplessly. "He said the ice bucket was almost full of ice because he didn't feel a lot of water in it when he was carrying it!"

"What do you mean?" Qiao Yifan was even more confused.

"The bucket full of ice will have a small half bucket of water if it melts!" I rolled my eyelids.

"You mean there's something else in the ice bucket?!" Qiao Yifan suddenly realized and almost shouted!

But soon he showed his doubts again and asked me, "But nothing else was found in the ice bucket at the scene?"

"Mrs. Zhou, because you are still a criminal policeman, Lao Qi has already told you all the answers!" Hong Kaiyuan actually began to laugh at Qiao Yifan.

Qiao Yifan was enraged, and turned around and scolded: "Dead fatty, what the hell did you say to hear it?!" and glared at Hong Kaiyuan at the same time.

"Medical common sense!" Hong Kaiyuan didn't care at all, and said triumphantly: "Didn't you say that they died of suffocation? And the acidity in the blood sample is very high, right!"

Qiao Yifan was still a little puzzled, and turned to look at me again in confusion, I nodded and didn't answer.

"This shows that they have been in an environment with high carbon dioxide concentrations for too long!" Hong Kaiyuan finally said what I didn't say.

"Damn!" Qiao Yifan finally fully understood, and pulled the last word into a long tone. "You two mean it's dry ice in there!!"

"No, Officer Qiao, why are you so foul-mouthed?" Wen Jing said with a smile.

"It's not that I've been with your old Qi for too long!" Qiao Yifan immediately joked after a moment's enlightenment, "I'm infected!"

"It's finally enlightened!" Hong Kaiyuan took a puff of cigarette and sighed, his tone full of ridicule.

And at this moment, Qiao Yifan didn't care about it at all, and his mood to clear the fog was so good that he couldn't care about this, so he immediately asked me to sort out all the clues and analyze them to him.

Actually, it's not very complicated, and with a little attention, you should be able to find clues.

When I entered the site, I didn't pay attention at first, but the ice bucket was really big, and it looked really unsightly, and it seemed to be more than twice as large as a normal ice bucket from the appearance, and I immediately concluded that the volume of this ice bucket was more than four or five times larger than that of ordinary ice buckets!

So my attention was drawn to it as soon as I could, and after some reasoning, I came to my own judgment.

Last night, after the three men entered the KTV, they called three young ladies to accompany the singing, and of course they ordered three high-end red wines. And the murderer took advantage of this, because in the KTV, the lady will not stop if you don't let you order a few red wines, and if the guests don't want it, they will do it for themselves.

When the murderer learned that they called red wine, he immediately put the prepared dry ice into an ice bucket and added some white wine (or alcohol), because alcohol can make the dry ice volatilize faster, and it will not freeze again, if it is just water, the effect will not be too good. After putting the dry ice, the red wine is inserted into the ice, and finally a layer of ordinary ice is added on top of the dry ice.
