Confusion as bodies of Noelene and Yvana Bischoff leave Bali The bodies of Noelene and Yvana Bischoff have been returned to Australia but not before confusion surrounded their release from a Bali morgue. Ms Bischoff, 54, and her daughter Yvana, 14, died in mysterious circumstances in Bali within hours of each other on January 4 after becoming violently ill at the start of their two-week holiday in Bali. The pair, from the Sunshine Coast, arrived back in Brisbane at 5.09am Saturday on Virgin Australia flight VA4198 after a week of wrangling between Indonesian and Australian authorities. Their bodies were taken to the John Tonge Centre at Coopers Plains, in Brisbane's south, for autopsies and formal identification. But before their final flight home, their departure was cloaked in mystery amid confusing scenes at the Sanglah Hospital morgue in Denpasar. As the two coffins left the morgue, covered in black fabric, identification documents taped to the top indicated they contained a Russian and a Dutch citizen. No Russian citizens were listed in the morgue, according to Sanglah Hospital records. A morgue staffer told Fairfax Media he was unsure whose bodies were in the coffins, although the Bischoffs were definitely no longer there. The confusion was short-lived. Both mother and daughter were formally identified in Brisbane on Saturday morning by Ms Bischoff's brother-in-law, Kevin Bowe. Shortly after the plane landed, Ms Bischoff's brother, Malcolm, said getting them home was an important step. Queensland's acting Attorney-General David Crisafulli said investigations into the cause of the Bischoffs' deaths, including autopsies and associated specialist analysis, would begin immediately at the request of the Queensland State Coroner. "While everyone wants answers swiftly, it is impossible to say how long these examinations may take until the pathologist has conducted his examinations," he said.
