Aeryn Gillern disappeared on October 29th, 2007. He was living in Vienna Austria, and working for UNIDO at the time.

Police ruled it spontaneous suicide, and they didn't even have a body! The story of Aeryn Gillern is one that, I'm afraid, has a lot of dark secrets and it may takes years before we find the truth if ever, but Aeryn's case should NOT be forgotten.
