A much-loved English teacher found a flatmate online and invited him to move in with her.
Within four weeks, the new housemate had killed Annette Brennan and threw her body into a green waste bin in an "extremely callous act", a court has been told.
He swapped bins with a neighbour and left the 67-year-old outside another property on bin day.
By the time waste workers found the teacher's remains, days later at a tip in Melbourne's north, Ms Brennan's body was so badly mutilated that a cause of death could not be found.
Her killer, Stephen Fleming, could be released from prison in less than a decade after he accepted a sentence indication and pleaded guilty to manslaughter, a few months before a trial was due to begin.
He refused to board a prison bus to attend Melbourne's Supreme Cour
