Munir was
poisoned with arsenic on a flight from
Jakarta to
Amsterdam on 7 September 2004. He was travelling on state-owned airline
Garuda Indonesia Boeing 747-400 registered as PK-GSG. It was concluded from Munir's autopsy and eyewitnesses during the trial that he had died two hours before arrival in
Schiphol International Airport. He unknowingly ingested the
arsenic during his flight transit in Singapore, or sometime near that time. In Singapore,
Pollycarpus Priyanto, a Garuda pilot at the time and the prime suspect in Munir's trial, left the flight and then went back to Indonesia. Originally he departed from Indonesia by
deadheading, with a fake document which allowed him to fly on another flight which was not his scheduled flight. Munir began to suffer acute diarrhea and bouts of vomiting shortly after his flight took off from Singapore to Amsterdam. The cabin crew informed the pilot in command that a passenger was sick, and a doctor who happened to be on the plane was asked to provide medical assistance. However, Munir died around two hours before the plane landed at
Amsterdam. When the results of the autopsy were released two months later, on 12 November,
the Netherlands Forensic Institute revealed that Munir's body contained a level of arsenic almost three times the lethal dose. This was later confirmed by
Indonesian police. There were three suspects; Pollycarpus Budihari Priyanto, a former pilot who allegedly gave up his business class seat to Munir during the flight, and two flight attendants. It is alleged that Pollycarpus placed the
arsenic in Munir's orange juice, upon orders from Garuda's chief executive at that time, Indra Setiawan. Indonesian president
Susilo Bambang Yudhoyono proclaimed that he will make sure that Munir's killers are brought to justice and quickly convened an independent investigation. However support and resources for the investigation waned, senior officials refused to comply, and the findings were never released. In December 2005, Pollycarpus Budihari Priyanto was found guilty of Munir's murder by an Indonesian court and sentenced to fourteen years imprisonment. Munir's supporters claim that Pollycarpus was acting on orders and that this was not brought out during the court case. In October 2006, the
Supreme Court of Indonesia invalidated the conviction against Pollycarpus, citing insufficient evidence. In October 2007, Indra Setiawan and his deputy, Rohainil Aini, faced trial for providing Pollycarpus with fake documents to board Munir's flight from Jakarta to Singapore. They would have faced a possible death penalty. They were both convicted and imprisoned for Munir's murder, and have appealed their convictions. In 2007, a Jakarta court found that Garuda was negligent in refusing to perform an emergency landing, and ordered the company to pay 600 million
rupiah in compensation to Munir's widow. When Garuda appealed this decision, the supreme court increased the compensation to an undisclosed amount. Garuda then failed to pay the compensation. In November 2014, Pollycarpus was released from prison, having served nine of his sentenced fifteen years. He died on 16 October 2020 due to COVID-19 during the COVID pandemic after being treated for 16 days.
State Intelligence Agency involvement in assassination Top-level
Indonesian State Intelligence Agency (BIN) officials were implicated in Munir's murder. The chief of police at the time,
Sutanto, allegedly knew of the BIN involvement. A BIN deputy chairman,
Muchdi Purwopranjono, was tried and acquitted for the murder in what has been internationally condemned as a "
sham trial". Prior to the murder Pollycarpus made at least 26 calls to Muchdi, and a number of calls to a confidential BIN line. ==Posthumous honours==
