Mystery still surrounds gold prospector's murder
Schuler, a retired builder, had been gold prospecting in a dry gully on Palmerville Station with three friends when he disappeared.
In July 2015 at the Supreme Court in Cairns, the station's owners, Stephen Struber and Dianne Wilson-Struber, were found guilty of his murder and with interfering with a corpse.
It was a murder case without a body or any direct forensic evidence linking the couple to Schuler's death.
The trial heard police found drops of Schuler's blood, burnt patches of grass, and tyre marks matching the Strubers' car in a gully about two kilometres from the homestead.
The Crown's case rested on the evidence of Schuler's fellow prospectors who reported hearing two gunshots several minutes apart after a vehicle matching the Struber's pulled up in the area where they were searching for gold.
The prospectors were on the Struber's land without permission, and one of them had been confronted by Stephen Struber about a week prior and was told him to get off his land.
