A Riverside man's evidence that three Victorian drug dealers shot Jake Anderson-Brettner was a complete and utter fantasy, Director of Public Prosecutions Daryl Coates SC told a Supreme Court jury in Launceston.
In summing up the 10-day trial, Mr Coates said that Jack Harrison Vincent Sadler, 29, planned to execute and then dispose of Mr Anderson-Brettner in a brutal way which showed how angry he was with him.
Mr Sadler has pleaded not guilty to the alleged murder on August 15, 2018, at his house at Dion Crescent, Riverside.

However, in his summing up defence counsel Greg Richardson said that evidence of a third person's DNA on the handgrip and trigger guard of the pistol was enough to ensure acquittal.
"What the hell is someone else's DNA doing on that pistol?" he said. "Somebody else fired it and dropped it on the ground, that creates a reasonable doubt on its own. That's enough to ensure acquittal."
He said that Mr Sadler's DNA was certain to be on the pistol because of repeated touchings.
But Mr Coates said that forensic evidence did not support Mr Sadler's version.
"You might think that even a Victorian drug dealer might be nervous and sweaty and might shed DNA everywhere, but there is no evidence of that," he said.

He said that Mr Sadler's DNA was found on the magazine, silencer, handgrip, trigger guard, outer surface and muzzle of the Smith and Wesson 9mm self-loading pistol.
He said forensic scientist Carl Grosser's evidence showed that the percentage of Mr Sadler's DNA in the swabs on areas of the weapon was up to 98 per cent compared with a second contributor.
"On the handgrip 80 per cent of the DNA was Mr Sadler's and 20 per cent someone else's," he said.
"On the trigger guard, 98 per cent of the DNA was Mr Sadler's and two per cent someone else.
"On the vacuum bag in which the gun was found it was 90 per cent Mr Sadler's."
Mr Coates urged the 10-man and two-woman jury to consider the whole of the evidence in the circumstantial case. If Mr Sadler's evidence was true about a confrontation between the Victorian drug dealers and Mr Anderson-Brettner before he was killed "they must have been the quietest drug dealers ever".
He said it was unchallenged evidence from Mr Sadler's partner at the time, Gemma Elizabeth Clark, that she heard only two voices.
Mr Coates cited three times during Clark's evidence that she said there was nobody else there.
"Did you only hear two people?" he quoted from the transcript. "Yes," Clark said in evidence.
Mr Coates said that Mr Sadler's demeanour in the witness box did not reflect what jury members might have thought was an extremely distressing event.
"He didn't seem too distressed when giving evidence yesterday, he seemed more concerned with telling what a good drug manufacturer he was," Mr Coates said.
He said that Mr Sadler's evidence that he was terrified after the drug dealers killed Mr Anderson-Brettner did not accord with a shopping trip expedition and a gym visit the day after.
Mr Coates said Mr Sadler's actions after the shooting were consistent with a number of aspects of the song Dead Body Disposal that Clark said Mr Sadler was listening to "all the time".
"The major things he did are consistent with the song, cutting the body into six pieces, double-bagging body parts, putting chilli powder and baby oil in the garbage bags and disposing of the bags in wheelie bins," he said.
He said the actions were consistent with Mr Sadler being angry with Mr Anderson-Brettner, meeting with former lawyer Adrian Hall to discuss disposing of a body and missing persons details, buying plastic gloves and materials, the song and Clark hearing just two voices at the house.
The jury is expected to consider its verdict today after a summing up and listing of alternative verdicts by Justice Robert Pearce.
