"She was doing what she was entitled to do. In a most callous and cowardly manner you set upon her ... humiliating her before strangling her to death.

"The act of choking her to death so that she suffocated was callous, cruel and brutal."
He said Todd presented "an unacceptable risk" of reoffending calculated at "80 per cent".

Once home, he watched violent pornography and read news articles about his crime.
The court heard Todd was a sexual sadist who was obsessed with violent sex, rape and "snuff" films depicting a person being murdered.
He began watching pornography at the age of 11, and the videos he watched became increasingly violent.
Todd was told by family and friends his picture was on the news and he should talk to police. He reassured his girlfriend he was not involved in the murder and, after being driven to Broadmeadows Police Station, denied his involvement to police.
But in the face of overwhelming evidence, including CCTV footage of him stalking his victim, he confessed.
He told police he was attracted to Ms Dixon and followed her but did not plan to carry out the murder until the attack had begun.
