  The EGRET excess in the diffuse galactic gamma ray data above 1 GeV shows all
the features expected from Dark Matter WIMP Annihilation: a)it is present and
has the same spectrum in all sky directions, not just in the galactic plane. b)
The intensity of the excess shows the $1/r^2$ profile expected for a flat
rotation curve outside the galactic disc with additionally an interesting
substructure in the disc in the form of a doughnut shaped ring at 14 kpc from
the centre of the galaxy. At this radius a ring of stars indicates the probable
infall of a dwarf galaxy, which can explain the increase in DM density.
  From the spectral shape of the excess the WIMP mass is estimated to be
between 50 and 100 GeV, while from the intensity the halo profile is
reconstructed. Given the mass and intensity of the WIMP's the mass of the ring
can be calculated, which is shown to explain the peculiar change of slope in
the rotation curve at about 11 kpc. These signals of Dark Matter Annihilation
are compatible with Supersymmetry and have a statistical significance of more
than 10 stnadard deviations in comparison with a fit of the conventional
galactic model to the EGRET data. The statistical significance combined with
all features mentioned above provide an intriguing hint that the EGRET excess
is indeed a signal from Dark Matter Annihilation.
