Two teenagers have pleaded guilty to murdering a man in Launceston last year.
In a rare move, Justice Robert Pearce made the names of the accused minors public, given the nature of the "heinous" crime.
19-year-old Billy Ray Waters was reported missing on August 11, last seen on Holbrook Street in Invermay.
The body was found in bushland at Mayfield days later.
Early police reports indicated screams and a gunshot were heard by neighbours in the area the week prior.
On Friday, the Launceston Supreme Court heard the victim was shot in the upper leg with a sawn-off shotgun, bashed, stabbed at least 18 times, before finally being shot in the head.
18-year-old William Adair Rothwell and 17-year-old Jacob Michael Brennan, former friends of the deceased, admitted they believed Mr Waters had stolen an ounce of cannabis from them.
Another man had given them the weapon and told them he'd give them an ouce of marijuana each, if they killed Mr Waters.
They'll be sentenced at a later date.
