GlobalPost has three articles (How the US and allies ignore organized crime at the highest levels of a new democracy, Assassinations and intimidation and A hotbed of human trafficking) on organized crime in Kosovo.
In the articles are links to two external sources: one is a NATO/KFOR presentation on organized crime in Kosovo. Instead of a pdf they use their own type of presentation software that tends to stop after a couple of slides. What I have seen (the first 12) are maps of Kosovo with names of local mobsters and their gangs. In a NATO report from 2004 close associates of Thaci are extensively described.
