Story summary

In 1998, Joanne Butterfield disappeared from a home near Mowbray, south of Port Douglas, Queensland. Two days later, some of her belongings were found 160 kilometers away. The case was initially handled by Detective Graeme Eaton, who after four years concluded that three theories could explain Ms Butterfield's disappearance: suicide, foul play, or voluntary departure. During a recent coronial inquest, Mr Eaton testified he believed it was most likely she had taken her own life. The investigation also explored the involvement of two male associates; however, details on whether Mr Eaton checked their criminal backgrounds are unclear. Witnesses are expected to be questioned further as part of the ongoing inquiry into Ms Butterfield's disappearance and the adequacy of the original police investigation.

🔮 The inquest has heard Ms Butterfield's landline made frequent calls to the number of a Cairns man named Victor Varga in the weeks before she went missing but police didn't follow that up until two decades later.

It took police more than 20 years to speak with a man who likely had frequent phone contact with missing Far North Queensland mother Joanne Butterfield in the weeks before she disappeared, a coronial inquest has heard.
🔮 To some, Ms Butterfield appeared troubled in the lead-up to her disappearance, telling friends and acquaintances her children would be better off if she left town.
