A woman who led police to a body part belonging to Jake Anderson-Brettner has been jailed for her role in concealing his murder.
Gemma Elizabeth Clark pleaded guilty to being an accessory after the fact to murder and failing to report the killing of Mr Anderson-Brettner.
It was alleged the 24-year-old victim was killed at a Riverside house on August 15 last year.
Clark, of Riverside, initially lied to police in the days after the murder, but she eventually cooperated with them and led them to the place where part of Mr Anderson-Brettner's body was found.
Justice Robert Pearce said Clark gave police further information that led to the collection of other evidence, but her admission was only after the gravity of the situation was apparent to her.
Clark was well-educated, from a good family, held many part-time jobs and was an aspiring primary school teacher.
Justice Pearce said the crime was an isolated and aberrant incident committed by a person of otherwise good nature, but it was a serious departure and good character did not carry much weight for a crime of this seriousness.
Details of Clark's involvement in concealing the crime are unable to be published due to a Launceston Supreme Court suppression order, but Justice Pearce said she committed crime's of considerable gravity.
"Her conduct added greatly to the distress of the victim's mother, his partner and the rest of his family and friends, and will likely have a lasting impact," Justice Pearce said.
Mr Anderson-Brettner's mother and fiance submitted victim impact statement's to the Launceston Supreme Court.
Jack Harrison Vincent Sadler has pleaded not guilty to murdering Mr Anderson-Brettner.
Clark is expected to give evidence during the accused murderer's trial, which will likely be held at the end of this year or early in 2020.
For her willingness to testify against Mr Sadler, Justice Pearce gave Clark a 20 per cent reduction in what could have been an eight-year sentence.
She was also given a 10 per cent discount on the sentence for her early guilty pleas.
"Mr Anderson-Brettner's family will not be exposed to the trauma of a trial, at least for Ms Clark's crimes," Justice Pearce said.
"The early plea also satisfies me that despite the absence of immediate remorse she came to appreciate the appalling wrong she had done and formed the intention to do what she can to make amends, although of course she can never fully do so."
Clark was sentenced to five and a half years' jail and was eligible for parole after three years.
Her sentence was backdated to August 2018.
