The investigation into Kabila's assassination led to 135 people – including four children – being tried before a special military tribunal. The alleged ringleader, Colonel Eddy Kapend (one of Kabila's cousins), and 25 others were sentenced to death in January 2003, but not executed. Of the other defendants 64 were jailed, with sentences from six months to life, and 45 were exonerated. Some individuals were also accused of being involved in a plot to overthrow his son. Among them was Kabila's special advisor Emmanuel Dungia, former ambassador to South Africa. Many people believe the trial was flawed and the convicted defendants innocent; doubts are summarized in an "Al Jazeera" investigative film, "Murder in Kinshasa".
