A jury has convicted two men of killing 68-year-old Raymond Smith, who was tied up and stomped on during a drug-fuelled home invasion in the WA town of Greenbushes.

A third man who was also involved in the burglary became a key witness and helped convict James Terence Hunt of murder and Paul Douglas May of manslaughter.

Two men have been found guilty of killing an elderly man in his own home in Western Australia's South West during a meth-addled burglary for drugs.

Raymond Smith, 68, died during a home invasion in the town of Greenbushes, about 240 kilometres south of Perth, in December, 2023.

He was reported missing in the days after the home invasion and his body was eventually found by homicide detectives on the outskirts of the town almost a month later.

At a Supreme Court trial, James Terence Hunt, 33, has been found guilty of Mr Smith's murder, and Paul Douglas May, 43, guilty of his manslaughter.

Mr Smith lived alone in his Greenbushes home, where he grew marijuana which, the trial heard, was why he was targeted for burglary by Hunt, May and a third man, Kevin Allan Craig Potter.

The trio were methylamphetamine users and had injected drugs before the burglary.

Potter, a friend of Mr Smith's who admitted betraying him, was the key witness against Hunt and May.

The 37-year-old had described himself during the trial as a "weak-hearted scumbag."

"I betrayed his trust for the sake of a robbery for drugs," Potter told the court.

Hunt and May showed no reaction as the jury read out the verdicts.

Testifying to the court, Potter described how on the day of the killing, he was at Mr Smith's home when Hunt and May arrived at the back door with beanies covering their faces.

He said Hunt dragged his friend by the back of his hair to the bathroom where May hit him, before Hunt tied Mr Smith up with plastic wrap and stomped on his chest and neck.

He said he felt panicked and frantic while "watching my mate have his life taken from him at the hands of James Hunt".
