I have followed their bloody trail for 20 years now.

As a Bosnian and as a photojournalist, I have tracked them through the ruins of Sarajevo — the target of concealed snipers and heavy artillery from the hills — to the mass graves of eastern Bosnia and the villages that were ethnically cleansed and destroyed forever, past houses, now owner-less, that nobody will rebuild and churches, barren of worshipers.
