it is a standard locked room mystery, looks like detective conan lol
there aren't enough clues to be able to solve it univocally btw

also, i guess you forgot to say that the murdered guy had the key of the room with himself, otherwise it wouldn't be such a "mystery"

where are the blotches leading?

That was actually supposed to be mentioned in there, I don't know why that info. wasn't in there. They went through the commons and got the master key. Also, I used my school's doors to base this on, and they are lockable with a key on both sides. At the time, I thought all school doors were like that, but that should have been mentioned in some way.

The blotches are leading to his corpse. DO you mean "where are the blotches leading from?"

of course

Okay, I'll tell you:

The door.

This info isn't truly needed, for one could come to the same answer if they really break down what they read, but this is just a beta for the riddle. I'm trying to find how difficult is too difficult. Honestly, I wouldn't be able to solve this riddle if my life depended on it, but I'm rooting for you all.

If you have a theory, you can put it down. There is no limit to the amount of guesses, so go ahead.

Martians.

Bingo.

He was stabbed with the key he was carrying.

No. An old key going through clothing and making a wound bad enough to kill a man is impossible. Plus, how would the killer go about getting to our victim?

Y'all can ask yes or no questions, now.

was student 1 the killer?
was student 2 the killer?
was student 3 the killer?
was student 4 the killer?


you should add that he was killed with some kind of sharp object in the riddle. also is there any broken glass around?

No students are numbered except the victim, who we refer to as number six, so I can't answer your first four questions, and I won't, even if you number them yourself.

Readers can figure that it is a sharp object on their own. He's in a pool of blood and a gunshot would be heard.

Where there are broken windows, you will find broken glass.

Just to be clear, to open the doors of a specific hallway, there is only 2 keys, the master key and the key of that spêcifik hallway. correcty?

How high is the window from the ground?Is the window closed?if so can it be closed from outside?

Its a Rock Climbing Camp that makes me assume they climbed up to the room from the outside of the building.

125ch209, you are correct about the keys. Also, the windows on the first floor can be climbed through. The window is not opened, but it is old. I think it's safe to say that it could be opened from the outside.

Poseidó̱nas, You are on the right track :D

Probably climbed down from the first floor

why is the broken glass on the floor?
that means that all the windows were smashed from the outside rather than the inside, some rooms only had windows, how is that possible?

He did climb down to the first floor.

But, it gets more specific than that.

wait never mind i misinterpreted the only windows thing :P
