  We carry on a new analysis of the sample of MACHO microlensing candidates
towards the LMC. Our main purpose is to determine the lens population to which
the events may belong. We give particular emphasis to the possibility of
characterizing the Milky Way dark matter halo population with respect to the
LMC one. Indeed, we show that only a fraction of the events have
characteristics that match those expected for lenses belonging to the MACHO
population of the Milky Way halo. This suggests that this component cannot
explain all the candidates. Accordingly, we challenge the view that the dark
matter halo fraction of both the Milky Way and the LMC halos are equal, and
indeed we show that, for a MACHO mass in the range 0.1-0.3 M$_\odot$, the LMC
halo fraction can be significantly larger than the Milky Way one. In this
perspective, our main conclusion is that up to about half of the observed
events could be attributed to the LMC MACHO dark matter halo.
