JAKARTA , Indonesia ( CNN ) -- Angry protests greeted the acquittal Wednesday of a former Indonesian intelligence official accused of killing a respected human rights activist four years ago . Muchdi Purwopranojo was accused of plotting the murder of lawyer Munir Said Thalib . A court in Jakarta cleared Muchdi Purwopranojo of murder charges in the September 2004 death of Munir Said Thalib , a lawyer heavily involved in human rights work . Protesters outside the courthouse chanted , `` Who killed Munir ? Muchdi killed Munir . '' Munir 's widow , Suciwati , said she was angry and disappointed in the verdict . And Usman Hamid , head of the National Commission on Missing Persons , said the family `` is hurting from the verdict . '' `` The decision has turned people 's faith in the justice system upside down , '' said Hamid , who now leads Munir 's organization . Munir died after being poisoned while on a flight to the Netherlands . Munir 's supporters say he was the victim of a conspiracy by Indonesia 's national intelligence agency , the BIN . Two other people have been charged and convicted in Munir 's death -- a pilot for the national airline Garuda Indonesia who was directly linked to the poisoning , and a former Garuda official who authorized him to be on the same flight . Prosecutors argued that Muchdi gave the orders in the conspiracy . But Hamid said judges treated the case as a personal vendetta by Muchdi , and he said more people from the agency should have been implicated .
