Trnopolje, located near Kozarac, consisted of a two-storied school building and what had been a municipal center with an attached theater.
Trnopolje held as many as 4000 prisoners, most of whom were women, children, and older men. When Omarska and Keraterm were closed in August, surviving prisoners were moved to Trnopolje.
Conditions at Trnopolje were dangerous, though somewhat less lethal than those at Omarska and Keraterm. Prisoners were interrogated, beaten and sometimes executed. No food was distributed except that brought by the local population, including Serbs.
Rape was especially prevalent. Girls between the ages of sixteen and nineteen were at the greatest risk, though at least one victim was as young as twelve. Some women were subjected to gang rapes.
Trnopolje was also a center for deportation. Deported prisoners were often first forced to sign an agreement to “voluntarily” relinquish all of their property.
In early October 1992, Trnopolje was officially closed, though some prisoners remained, since their homes had been destroyed or taken by others.
