Anna Jane Chaney's Autopsy Reveals a Bruise on the Top of Her Forehead

Anna Jane Chaney's autopsy was conducted by Dr Colin Manock, the senior director of forensic pathology at South Australia's Forensic Science Centre. He couldn't find any trauma that would have rendered Anna Jane unconscious, but he did notice a 3 centimetre circular bruise on the top of her forehead which appeared to have occurred shortly before she died. Blood and tissue samples were taken from her lungs, heart, and brain for further testing and to exclude any significant medical conditions. The provisional cause of death is freshwater drowning. A range of factors, such as injury, heart attack, stroke, and severe allergic reaction, need to be ruled out before drowning can be concluded as the cause of death.
