You can read the Wikipedia article "Republic of Crimea (1992–1995)" which is extremely well sourced with link to NYT articles of the period and some good academic papers from before the 2014 invasion. That's if it hasn't been defaced of course. Crimea is a contentious point of the current conflict.

I don't really understand your point about real "owners". Crimea today is de facto Russia and de jure Ukraine on the basis of the 1994 agreement (I think we can safely ignore the 9 countries which accepted the results of the 2014 referendum). Their unique situation regarding the rest of Ukraine is that they have been at odd with the federation more often than not and have consistently voted for pro-Russian politicians to the point that Ukraine had to military removes their government once. It is very different from what's happening in the other invaded provinces.
