A man who murdered a respected police officer in a premeditated ambush as he tried to serve a home repossession order will spend up to 40 years in jail.
Leigh Geoffrey Sushames was sentenced on Friday for fatally shooting veteran Constable Keith Smith, 57, on his rural property in Tasmania on June 16, 2025.
Const Smith went to the door of Sushames' home with Sergeant Gavin Rigby to deliver the order while specialist police waited further away.
The pair encountered Sushames, who was crouched behind a blue Ford Falcon in the carport holding a rifle.
Const Smith asked Sushames how he was going.
He replied "not good" before standing up and shooting Const Smith in the back and then in the head from less than two metres away while he lay prone on the ground.
Sushames pleaded guilty in January to murder as well as aggravated assault for pointing the gun at Sgt Rigby's head.
Body-worn camera footage from Sgt Rigby showed Sushames unequivocally intended to kill Const Smith, Justice Tamara Jago said during sentencing in the Supreme Court of Tasmania in Burnie.
"He stood no chance against your murderous intent," she said.
"He would not have had time to arm himself or take evasive action. This was a premeditated ambush."
Sushames knew Const Smith and Sgt Rigby would be returning to his North Motton home on June 16 to deliver the order after the pair visited a month earlier.
The job was assessed as low risk, with Sushames previously showing no hostility towards police.
"(It was) a deadly attack for reasons not clear, but carried out for feelings of misplaced resentment," Justice Jago said.
Sushames had fallen behind on mortgage repayments and had previously told a friend he would kill anyone who tried to take his house off him.
He believed God would intervene and sort out his mortgage problems
Since the crime, Sushames has been diagnosed with post-traumatic stress disorder as a result of a difficult upbringing including witnessing the death of his brother as a child.
However, this didn't reduce his moral culpability, Justice Jago said.
She said Sushames had shown remorse but the crime was a grave case of murder.
The 47-year-old was jailed for 40 years with a non-parole period of 25 years.
The impact of Const Smith's death while undertaking a routine duty had reverberated throughout the police force, Justice Jago said.
Const Smith, who served for 25 years, was farewelled with a police funeral and full ceremonial honours.
A community policing award has been named in his honour, while a laneway near the station where he worked is now "Keith Smith Lane".
A ceremony was held to mark the first anniversary of his death, with his love of cycling and a catch-up over a hot brew fondly remembered.
