Assassination in Tasmania: a “ cold-blooded execution ”


After gunning down and dismembering his friend in an execution-style murder, Jack Harrison Vincent Sadler traveled across northern Tasmania, dumping his body parts in wheelie bins.

Sadler was sentenced to 32 years in prison on Friday for the murder of Jake Anderson-Brettner, an act Judge Robert Peace called calculated and cold-blooded.

The killer lined a small room in his home in Launceston with plastic before inviting Mr. Anderson-Brettner on the night of August 15, 2018.

There he shot him at least three times with a pistol, once while he was on the ground.

Judge Pearce said he could not determine exactly what motivated the crime, but noted that Sadler was “angry” with his friend, possibly because of illegal drugs.

Gemma Clark, then Sadler’s girlfriend, was in the next room and overheard Mr. Anderson-Brettner say “please man don’t do it”.

She had previously purchased bleach, fire starters, gloves, coveralls, safety glasses, a saw, cling film, vinegar and reusable bags at Sadler’s request.

She also bought cayenne pepper and chili powder, which were used to mask the smell of Mr. Anderson-Brettner’s leftovers.

After Sadler severed the body, the couple searched for suburban trash pickups online in the morning.

They drove around Launceston and threw bags full of leftovers in trash cans. They have never been found despite extensive research.

Mr Anderson-Brettner’s torso was thrown onto the side of a highway in the bush about 40 kilometers outside of Launceston.

He was discovered a few days later, triggering the police investigation.

Sadler appeared from prison via video link to the court and was still when sentencing was handed down.

“It was intentional murder in cold blood, committed after some planning and preparation,” Justice Pearce said.

Sadler had an “absence of remorse”, tried to cover up his tracks and lied to police during interviews, the judge added.

Sadler had pleaded not guilty, but the jury rejected his version of events that Mr. Anderson-Brettner was shot dead by anonymous drug traffickers in Victoria.

Justice Peace said the traumatic effect of the murder would impact Mr. Anderson-Brettner’s family for the rest of their lives.

“Nothing would ever bring Jake back,” his mother Claudette Brettner said from the court.

She said she hoped Jack could change his life after taking the wrong road.

“I hope God will. That’s all I can hope for. While he breathes, there is still hope that he can change.”

Sadler’s sentence was backdated to August 2018 with a 20-year non-parole period.

Clark is serving a five-and-a-half-year prison sentence after previously pleading guilty to being an accomplice after the fact and failing to report the murder.

In the aftermath of the shooting, the two men destroyed evidence, cleaned the house with bleach, and burned the curtains and carpet in the room.

The gun was vacuum-packed and concealed in the garden, while the ammunition and silencer were stuck in PVC pipes and hidden.

Mr Anderson-Brettner’s partner visited the house the morning after the murder after he failed to return home.

Sadler told him he was looking for him.
