A man connected to a notorious missing persons case in far north Queensland has been found dead in a public toilet block.
The body of 24-year-old Brian Dunnett was found in Weipa early on Saturday morning.
He was a deckhand on the El Dorado fishing boat with Bevin Simmonds and his son Brad, who both disappeared in mid-2003.
Mr Dunnett had been charged with stalking Michael Gater, who was found not guilty of the Simmonds murder after a Supreme Court trial.
The stalking charges were later dropped.
Acting Detective Inspector Brad Eaton says police have been interviewing several witnesses over Mr Dunnett's death.
"Obviously we're looking at the circumstances surrounding this young man's death," he said.
"At this stage we're treating the death as suspicious until we get the result of a post-mortem examination, which should be conducted in Cairns on Wednesday sometime."
