WA State Coroner Alistair Hope has found the death of Karratha woman Tracy Margaret Marshall, 35, was “established beyond all reasonable doubt”.
A coronial inquest was held into Mrs Marshall’s death, with Mr Hope making an open finding as to how her death occurred.
Mrs Marshall left Nickol Bay Hospital on February 21, 2011, and has not been seen since.
During the inquest Mr Hope concluded that at the time Mrs Marshall left the hospital she was continuing to show signs of psychotic illness.
“While Mrs Marshall had definitely expressed suicidal thoughts in the period shortly before she went missing, it is not now possible to determine whether she intentionally acted to take her own life or whether, affected by mental illness, she lost her way and died as a result of dehydration or exposure,” the conclusion read.
“Other possible explanations for her being missing present themselves, but in the absence of any evidence these would be pure speculation and no conclusions can be drawn.”
During the inquest it was revealed Mrs Marshall continued to have issues with self-confidence, anxiety and concentration.
Mr Hope found Mrs Marshall’s illness was not being treated properly.
In evidence given during the inquest, Mrs Marshall’s husband Iain expressed surprise his wife had gone missing.
“He stated that he had been concerned that she was suicidal and did not understand that she was not an involuntary patient at the hospital,” the inquest findings said.At the time of Mrs Marshall’s disappearance, tropical cyclone Carlos was affecting the Pilbara coast and Mr Hope found this limited the extent of the search and may have removed traces of Mrs Marshall’s movements.
