"Appropriate and highly responsive."
That's the way Corrections has described its handling of Tony Robertson, the man with a comprehensive and disturbing criminal history who killed Blessie Gotingco just months after he was released from prison.
Robertson was wearing a GPS tracking bracelet at the time. His movements were a key part of getting him convicted, but he repeatedly breached the strict conditions of his release.
Corrections was clearly worried. It applied for an extension supervision order that would have seen Robertson monitored for the next 10 years. It was due to come into force in June 2014, but Ms Gotingco was murdered in May.
Corrections' northern regional commissioner Jeanette Burns says the department did what it could to prevent him reoffending.
"Despite all of this, no matter how much monitoring we have around some offenders, they can go on to commit these heinous crimes."
But why was he freed in the first place?
