Samuel John Shephard has been sentenced to 27 years' jail for the brutal murder of Wagga woman Allecha Boyd and large-scale drug supply.
Shephard, who pleaded guilty in October 2019 to murdering Ms Boyd, was sentenced in a NSW Supreme Court sitting in Wagga on Friday.
Justice Richard Button sentenced Shephard to a total sentence of 27 years and seven months, with a non-parole period of 20 years and eight months, on the charges of murder and supplying a large commercial quantity of methylamphetamine.
Ms Boyd was last seen travelling as a passenger in a green Subaru between Wagga and Coolamon on August 10, 2017.
Ms Boyd was 27 when she was driven to Shephard's home to buy drugs the day she died.
She was later taken to the outskirts of town, where she was confronted by a woman over an alleged break-in at her home. Shephard then used a pistol to shoot Ms Boyd several times before he and another man, Anthony Shane Hagan, buried her in the Lester State Forest.
Her body has never been recovered, despite six intensive searches of the state forest, southwest of the Coolamon township.
Shephard is the third person to be sentenced over the death of Ms Boyd.
He was committed to stand trial in the NSW Supreme Court in March before pleading guilty in October.
Hagan, from Mount Austin, is serving an almost five-year sentence after admitting in late 2018 to burying Ms Boyd's body in the state forest.
Hagan said he helped dig a grave and covered her body with dirt and small branches. He was convicted of being an accessory after the fact, and with the sentence backdated to when he was placed in custody in 2017 and a non-parole period of three years, he could be released as early as November this year.
Tracy Lee King, Shephard's partner, was jailed in December after also pleading guilty to being an accessory after the fact.
King was aware Shephard killed Ms Boyd by October 24, accusing him of murder and asking him about the woman's location in a voicemail.
She also sent Shephard additional text and voice messages outlining her knowledge of the murder but when police came to her home that afternoon, she told them she knew nothing.
King again lied to police in April 2018, telling them she knew nothing to protect him.
After her arrest, King admitted lying to police because she was scared and said Shephard had threatened to harm her if she told them.
