She repeated the call for a full and transparent investigation of the case during a speech given through a translator at the Foreign Correspondents' Club yesterday.

A pilot for the national airline, Garuda, is on trial over the killing and a verdict is expected in coming weeks. Few human rights activists believe that the man, Pollycarpus Priyanto, alleged to have links to the National Intelligence Agency, will be found guilty - of the dozens of rights cases in Indonesia since Suharto's downfall in 1998, no-one has been found guilty.

Fellow human rights activists are unsure what Munir, 38, was working on when he decided to take up a one-year course in international law at Utrecht University in the Netherlands. Some believe he could have been investigating the military, while others suggest it was corruption. Whichever, he was no stranger to threats and intimidation.

On the evening of September 6 last year, he said goodbye to his wife at Jakarta's Soekarno-Hatta Airport and boarded a flight to Singapore. After a short wait there, he got on a connecting flight to Amsterdam and fell ill shortly after eating a meal of noodles. He was moved to business class and a doctor on the flight pronounced him dead on the morning of September 7, as the plane was flying over central Europe.

An autopsy was carried out after his body was taken off the plane in Amsterdam and the Dutch coroner found it contained almost 500 milligrams of arsenic, about four times the amount that can kill.

Pollycarpus, who travelled on the same Jakarta to Singapore flight as Munir, was arrested six months later and charged with 'facilitating' the poisoning. Two more crew on the flight were taken in for questioning, but not arrested. Among others the investigators spoke to were former Garuda director Indra Setiawan, dismissed in a management shake-up, along with ex-corporate security vice-president Ramelgia Anwar and operations director Hermawan.

The government-sanctioned fact-finding team's report was given to Mr Susilo on June 23, and its recommendation of setting up a police unit to investigate those it named has already been carried out. Jakarta media reports say the fact-finding team concluded Munir's death was a conspiracy that allegedly involved top Garuda and intelligence officials. The 30-strong police team, comprising detectives and forensic experts, has yet to report progress.

Ms Suciwati and Indonesian and international human rights groups have made pushing for the fact-finding report's release the centrepiece of a campaign to find out who is behind Munir's death. They suspect Mr Susilo, a retired army general, does not want to release it because it implicates former colleagues or top-ranking military officials and that a political deal has been cut.

That such people might want Munir dead is highly likely - through his years of human rights work, he was a thorn in the side of many authorities.

Munir rose to prominence as an outspoken critic of the military in the chaotic years surrounding Suharto's downfall. At first, he worked with the respected Legal Aid Foundation before founding the Commission for Disappearances and Victims of Violence, better known as Kontras, in 1998. The group played an important role in the campaign for accountability after the disappearance of pro-democracy activists during the transition from authoritarian rule, and led human-rights investigations into state-sponsored violence in East Timor, Aceh and Ambon.

Two years ago, he co-founded the non-governmental organisation Imparsial and was its executive director when he died. He also served on the commission to investigate human-rights violations in East Timor during the annexed Indonesian province's struggle for independence in 1999, and was instrumental in uncovering Indonesian military involvement and recommending action against high-ranking officers.

Workers also held him in high regard for his activism on labour issues. Indonesian domestic helpers in Hong Kong met Ms Suciwati, herself a labour activist before marrying Munir, in Victoria Park on Sunday to sing her praises and present her with a locally-penned book of poems inspired by her husband.

Later, she told the South China Morning Post of her growing despair for human rights in her country.

'After Suharto, the government enacted human rights bills, but that was just lip service,' she said. 'There has been a change in press freedom and freedom of expression, but there has been no progress on other issues, such as human rights and corruption.'

Wearing a T-shirt with a portrait of Munir and the words 'The only thing we have to fear is fear itself, because fear eliminates our common sense and intelligence', she recounted how his death had drawn her from being a housewife taking care of their children back to activism. Threats - such as a headless chicken left at her front door - had not frightened her off her goal of finding out who killed her husband.

At first, government co-operation had been good. Ms Suciwati had an official meeting with Mr Susilo and his secretary was open to requests for information. That changed after the fact-finding report was released.

'Since then, they have appeared to refuse to answer the telephone and are ignoring the letters I am sending,' she said. 'In a public discussion at [the central Java city of] Yogyakarta, the president's secretary had a discussion with students and one asked why the report had not been released.

'The secretary said the result was already known, so there was now no need to publish the report. The feeling was that the president should not be pressured over the issue - that he was helping me more than for any other case and that was enough.'

Unable to take her campaign further in Indonesia, she has moved it internationally to increase pressure on the government. Hong Kong was the latest of a series of trips that have included visits to the United Nations' Human Rights Commission in Geneva and to meet fellow activists in Taipei and Bangkok.

Foreign governments have also been writing to Mr Susilo to push for action. So far, the calls have fallen on deaf ears.
