Riven didn't killed the elder?!!!!

Most people think that Riven killed Yasuo's elder... I cant say this is wrong, but in my opinion I don't really think that Riven did it, I think it is one of Yasuo's tribe!

Here is my thought, there are two things that I think it is one of Yasuo's tribe. First please go read Yasuo's background, read it carefully you can see it said "Yasuo was the only student in a generation to master the legendary wind technique." The main word is "THE ONLY STUDENT IN A GENERATION" so it means this generation, how about the generation before this one? I suspect it might be the master of Yasuo who taught him the wind technique.

Second, while Yasuo fought his brother? Before Yone died, he said “The Elder was killed by a wind technique. Who else could it be?” Now yasuo know that the elder has been slain by a wind technique, but why didn't Yasuo knew? He had been chase by his own tribe again and again, but they didn't say shit XD, so that means that they just wanted to kill Yasuo, maybe the killer told them too, so he or she can hide the truth.

But this is just a theory, a game theory! Thanks for reading!
