The massacre was carried out by members of the special response team of the Public Security Center (CJB) of Prijedor, a Bosnian Serb reserve police unit.

In trials at the International Criminal Tribunal for the former Yugoslavia (ICTY) and the Court of Bosnia and Herzegovina members of the group who carried out the killings, including their leader, Darko Mrđa, were convicted and sentenced to various terms of imprisonment.

In the final major trial at the Court of Bosnia and Herzegovina, on 21 December 2010 Zoran Babić, Milorad Škrbić, Dušan Janković and Željko Stojnić, all employed at the Public Security Center in Prijedor during the war, were found guilty and between them sentenced to decades in prison for war crimes committed against more than 200 Bosniak and Croat civilians in the Korićani Cliffs massacre.

The separated men were told they were going to be exchanged for prisoners held by the Bosnian government forces, but instead they were taken on a 15-minute journey to the edge of a ravine at Korićani Cliffs.

Seven of them were found by members of the Army of the Republika Srpska (VRS), who filed a report on the "terrible crime against civilians," but the prisoners were not immediately released and some suffered further abuse while being treated for their wounds at the Hospital for Eye Diseases in Paprikovac.

[1] Appearing as a prosecution witness at the trial of members of the unit in 2009, Jefto Jankovic, former investigative judge with the Basic Court in Banja Luka, told how on 23 August 1992, after receiving a call from the Public Safety Station in Banja Luka, he went to Korićanske Stijene to conduct a crime-scene inspection: "We arrived there at about 3 pm We saw that the area was rocky, the canyon was about 100 to 300 meters deep.

"[2] Janković was then taken to the Staff Headquarters of the VRS 22nd Brigade in Kneževo, where he spoke to two survivors, Medo Sivac and Midhat Mujkanović, who told him how they had managed to survive by jumping down when the shooting started.

In the late 1990s, it published a series of reports detailing the Koricani shooting and the inaction of the authorities to find the killers, as well as the concealment of evidence and an incomplete examination of the crime scene.

At least two forensic experts from Banja Luka, Aleksandar Vodovnik and Slavisa Duric, examined the bodies in the ravine on 14 September 1992, and were referred to them by the assistant district attorney, Marinko Kovacevic.

Nezavisne Novine learned that the prosecutor's office had sent a request to the Interior Ministry for an investigation at least twice, but local authorities in Banja Luka sabotaged it.

[4] Kopanja believed that the entire Serbian people could not and should not bear the burden of responsibility and guilt for the crimes of individuals, and that the murderers must be identified and punished.

[12] Mrđa is believed to have been ordered to commit the crime by Simo Drljača, the chief of police of Prijedor, who was shot and killed by SFOR soldiers while resisting an attempt to arrest him in 1997.

[13][12][14] In May 2009, eight former members of the Public Safety Station in Prijedor and the Emergency Police Squad charged with crimes committed at Korićanske Stijene were brought to trial before the Court of Bosnia and Herzegovina.

[2][15][16] Damir Ivanković,[17] Zoran Babić,[18] Gordan Đurić,[19] Milorad Radaković,[17] Milorad Škrbić,[17] Ljubiša Četić,[17] Dušan Janković[17] and Željko Stojnić[17] were charged with crimes against humanity, as the Prosecution charged them with having participated in organizing and escorting the convoy of Croat and Bosniak civilians who were supposed to be exchanged on 21 August 1992, from which about 200 men had been separated before being shot with automatic weapons at Korićani Cliffs.

[20] Following exhumations at the ravine in August 2009, two more former members of the Intervention Squad and a Territorial Defense unit, Branko Topola[21] (a serving police officer) and Petar Čivčić,[21] were also arrested on suspicion of taking part in the massacre.

[22] On 21 December 2010 the Court of Bosnia and Herzegovina's first instance verdict pronounced Zoran Babić, Milorad Škrbić, Dušan Janković and Željko Stojnić guilty of participating in a joint criminal enterprise in Prijedor municipality conducted with the aim of persecuting, robbing and killing non-Serb civilians during the course of 1992.

[14] Gordan Đurić who had testified that he had not wanted to participate in the shooting of civilians and had sheltered behind a cliff but did obey orders to stand guard securing the location where the executions took place[23] was sentenced to eight years imprisonment.

[30][31] In December 2010 the Bosnian Institute for Missing Persons said an additional search will be carried out as it is believed another mass grave could exist at the Korićani Cliffs.
