Li Du and his group were there to assist in the investigation, but they had nothing to do with the dealings between the officials. As a matter of fact, since the case had not yet been solved, they were considered suspects as well.
As the police had graciously requested that they stay in Hobart, there were rooms prepared for them in the hotel next to the police station. Consequently, Li Du and his group did not leave after having their statements taken.
The entire Tasmanian police force was deployed, and Devonport and all of the nearby ports were sealed off. Following which, an investigation uncovered the truth behind the cargo container that the children were in.
Before long, the findings of the investigation were released. The company that owned the cargo container was an electronic waste trading company based in Indonesia that profited from helping Australia discard its electronic waste.
