An armed robber, who was involved in a ruse to trick a 14-year-old, forced his way into the boy's home and broke his dad's neck while demanding cash mistakenly believed to be inside.
A week later, the man burgled another home while armed with a knife and a crowbar.
Troy William Graham, 26, committed the violent crimes to fund his "ongoing and persistent problems with drugs", the ACT Supreme Court found on Tuesday.
