Never happened - the 100,000 were reported as unaccounted for, and in light of satellite imagery of places like Izbica, where the Serbs massacred over 100 K-Albanians, and against the context of Srebrenica, where the thin veneer of civilization proved too much of a hassle for the Serbs, Scheffer and Cohen speculated that they may have been murdered, and made clear in their comments that the men's fate was unknown (Cohen put the number of executed up to that point at 4,600, based upon intelligence reports).
Since the discovery of the K-Albanian corpses in Serbia's SAJ/MUP training grounds, the issue is moot - the Serbs were murdering K-Albanians, and felt guilty enough about it to try and hide the evidence of their crimes, just like at Srebrenica.
And just like at Srebrenica, they failed, but the differently enabled still feels compelled to take up the challenge of denying the historical record in order to propagate Serbia's claim to exclusive victimhood.
As to Kosovo's missing Serbs, of the ~2700 persons still carried as "missing related to Kosovo" by the ICRC, some 500 are Serb, 200 non-Serb/non-Albanian, and the rest Albanian, while UNMIK's OMPF reports (as of 1/1/05) that since it took over operations from the ICTY, it has identified 905 exhumed individuals, of which 705 were Albanian, 99 non-Albanian, and 99 awaiting return to their families (ethnicity unspecified).
If you choose to remain ignorant as to what's happening in Kosovo in regards to the missing, then you've got nobody to blame but yourself. - the information is published and available to the public, just be advised that if you're going to declare that the information isn't specific enough in regards to Albanians, then you had better get used to seeing your claims of Serb victims disallowed on the same grounds.
The ICTY exhumed ~4k bodies through 2000 and a further ~2k since in both Kosovo and Serbia, which put the total number of recovered victims at around 6,000 so far.
And we're still waiting on Belgrade to fully disclose the operation to dispose/hide K-Albanian victims from Kosovo during the war, so that tally's not finished yet.
And how many of those Albanians were killed by the KLA?
That's one of the details that Clinton's knee pad brigade doesn't want answered.
