• Did killer get locked up for long enough?

Queensland’s attorney-general has raised the possibility of appealing the sentence given to Daniel Morcombe’s killer.

Serial pedophile Brett Peter Cowan, 44, has been sentenced to life imprisonment, including 20 years without parole for the murder of the Sunshine Coast schoolboy.

Supreme Court justice Roslyn Atkinson sentenced Cowan to a non-parole period of at least 15 years, but said she felt his crime warranted a harsher penalty.

Attorney-General Jarrod Bleijie is now examining Cowan’s sentence.

“I am currently reviewing the sentence and seeking advice from the Director of Public Prosecutions,” Mr Bleijie told AAP.

“Murder is a heinous crime and one of this government’s first acts of parliament was to increase the non-parole period to 20 years for murder and 30 years for multiple murder.”

Cowan was also sentenced on Friday to three-and-a-half years’ imprisonment for indecently dealing with Daniel and two years’ for interfering with his corpse.

The sentences are to be served concurrently with his murder sentence.

The former tow truck driver has already spent two-and-a-half years in prison since his arrest in 2011.

Cowan already had two convictions for molesting children prior to 2003, when he abducted and killed Daniel, 13, on the Sunshine Coast.

In sentencing Cowan, Justice Atkinson said anyone considering granting him parole should exercise caution.

“Whenever anyone is considering the prospect of granting you parole in the future they should mark my words that you are a convincing, plausible and adaptable liar, and prepared to lie to advance your own interests,” she said.
