The Chief High Court Judge has rejected the notion that Christie Marceau's killer is remorseful.
Akshay Chand has today been sentenced to three years in prison for kidnapping the teenager, two months before she was killed.
Justice Winkelmann declared him insane, and therefore not guilty of murder.
Crown Prosecutor Simon Moore is satisfied with the sentence, and says the issue of remorse was key for the Crown.
"One of the issues that really does recur in this case is that the accused would often say 'I'm very sorry' and facts prove that wasn't the case."
The Marceau family says no sentence will ever be sufficient for the loss of their daughter, Christie.
Brian Marceau says the family doesn't agree with the ruling and is continuing to fight for changes to bail laws.
"I just can't come to terms with someone being guilty and not being guilty at the same time."
He says it's their aim now to do good, in Christie's name.
Tracey Marceau says the family is now focused on a campaign to change bail laws.
"I think after all that's come in the courts over the last couple of days is a strong indication that she was truly taken away from us unjustly, She had that right to life."
Mr Chand has also been sentenced to two years for threatening to rape, and one year for threatening to cause grievous bodily harm.
The sentences will be served concurrently, while he's a special patient at Auckland's Mason Clinic.
