THE mother and stepfather of a woman who tried to cover up her partner's murderous crime have described her jail sentence as a "travesty of justice for Allecha and her family".
King had pleaded guilty to being an accessory after the fact to the murder of Ms Boyd, whom Samuel John Shephard shot multiple times outside of Coolamon in August 2017.
With a non-parole period of one year and three months and having already served 13 months in custody, she will be eligible for early release on February 24 next year.
Speaking from Far North Queensland, King's mother, Wendy Butler, said she and her husband did not consider the sentence adequate given the role their daughter played in denying Ms Boyd justice.
Mrs Butler said her daughter always had a troubled history involving prohibited drugs and violence.
"She's a pathological liar and she chose this path," she said.
"She thought she could get away with it, but then she realised she couldn't so she spun a sob story to protect her drug racket."

Shephard, 37, is set for sentencing in February after he pleaded guilty in October to murder. Earlier this year, Anthony Shane Hagan, 21, was sentenced to four years and nine months' jail on a charge of being an accessory after the fact.
Mrs Butler said King "went from being a drug user to the 'drug secretary' for Shephard" after the duo met about 15 years ago.
She said when she was not surprised when her daughter was arrested in November last year.
Last week, the court heard that Ms Boyd was driven to Shephard's home to buy drugs the day she died.
Shephard and Hagan then drove her to the outskirts of town where Shephard shot Ms Boyd several times with a pistol.
After the murder, Shephard and Hagan buried her body in the Lester State Forest. It has never been found despite numerous police searches.
King, who became aware of the murder, lied to police twice to protect Shephard. After her arrest, she admitted lying to police, saying Shephard had threatened to harm her if she told them.
The court heard King suffered an upbringing of neglect, abuse and post-traumatic stress disorder.
In his sentencing remarks, Justice Robertson Wright emphasised that those factors contributed to her role in the murder.
He classified King's crimes at the lower end of objective seriousness but said Ms Boyd's life was "taken from her in appalling and cruel circumstances".
A Director of Public Prosecutions spokesperson said a decision in relation to an appeal has not been made.
As King proceeded through the courts, Mrs Butler and her husband, Jamie Butler, tried to extract information from her to help police find the remains of Ms Boyd.
"I tried to reach out to Tracy many times, but it fell on deaf ears," Mrs Butler said.
"Allecha needs to be brought home and laid to rest and the family deserves to have that."
Mr Butler, the stepfather of King, said the sentence should have been five years minimum as the one King received was inadequate to address the harm caused to Ms Boyd's family.
"She had plenty of opportunities to come forward to do the right thing, but she has a history of fabricating stories to protect her sorry arse to get out of problems," Mr Butler said.
Mr Butler, a behavioural therapist, dismissed King's defence on the grounds of mental health issues and troubled upbringing.
"She had a good education and she only floundered because in her late teenage years, she got herself mixed up in drugs and she's been an addict probably for the past 12 to 14 years or longer in some form or another," he said.
Speaking from Melbourne, Ms Boyd's aunty Cheryl Hoskin also said she would like to see the Director of the Public Prosecutions appeal the sentence.
"The police have worked so hard in their investigations since 2017, so it's got to be frustrating for them," she said.
She also paid tribute to her niece, saying she always had a positive outlook on life.
"She wanted to be a chef like Jamie Oliver one day - now that's never going to happen," she said.
"Until we can get her home and laid to rest in a dignified and proper manner, the pain isn't going to go away."
