First, see http://en.wikipedia.org/wiki/Regulus_Black --

I think the speculation around here is that "RAB" is Sirius' brother,
Regulas A. Black.  (Sirius and Regulus had an uncle named Alberforth,
thus the "A"?)  Based on some not-quite-but-pretty-close canonical
comments by the translators of HBP, this is confirmed.  Some said they
asked Rowling about this point because in some languages Regulus Black
has been cast into different names, and therefore the initials "RAB"
should be changed to match the translations.  So we have it
second-hand that Rowling confirmed their suspicions.  Next, Lupin
mentions that Regulus was a Death Eater, but he got into it a little
way and was freaked out / scared off by what he was being expected to
do and tried to quit.  Voldemort doesn't just accept people's
resignations, and Lupin said Regulus only lived a few more days.  He
doesn't come right out and say that the Death Eaters killed him, but
we are certainly left with that conclusion based on context of the
comments.  However I personally am holding out that Regulus may have
died when he tried to open / destroy the locket-Horcrux.  That's just
my opinion.

So, assuming all the above is right, the current thinking is that the
locket in OotP at 12 Grimmauld Place that nobody could open is, in
fact, that very same Horcrux.  Given Kreacher's propensity for
squirreling away precious artifacts, the locket may right now be in
his hovel off the kitchen at 12GP.
