In 2005, DeFaria was appointed director of the Serious Crimes Unit by Timorese President Xanana Gusmão. His task was to windup war crimes probes before the UN pullout on May 20, 2005. He faced some criticism that the UN was leaving before the war crime trial process was finished. He said, "Obviously, we would like to have all of the people who have been indicted brought to justice. It will be up to the Timorese government. I'm sure if they decide to pursue it, they will have a lot of support from the international community."
