On Monday Arunda pleaded guilty to misleading Australian police in order to help her husband escape punishment.
The 38-year-old was sentenced to ten months in prison but was immediately released on parole.
Arunga was charged with misleading the police after her three-year-old son Sinclair Timberlake died as a result of blunt force trauma to his abdomen.
Judge Martin Burns observed that Arunga’s beliefs had led to her tribulations as she tried to bring up a family in a foreign land, and worse still, losing a son in the process.
Arunga was convicted by Queensland court on Thursday in a case that has dragged on for years.
According to the Australian Associated Press, Crown Prosecutor Danny Boyle told the court that Ms Arunga had called the emergency services and told them that the boy had fallen down the stairs. An autopsy later revealed that the cause of death was “as a result of severe blunt force such as punching or stamping or similar”, which was not consistent with a fall.
Mr Boyle further said that Ms Arunga kept up the lie for 26 days only to open up when her husband was taken for a mental evaluation.
She then said that on the fateful night, she found Mr Timberlake hitting their son in the stomach and threw him against a wall. She had earlier told investigators that her husband was convinced that the boy had a devil in his stomach and he was trying to get it out.
