Acting on a tip-off, Queensland Police are focusing on Hughenden on the notorious Flinders Highway to investigate fresh leads.
One of the unsolved murders is that of 20-year-old hitchhiker, Tony Jones, who disappeared without trace while backpacking in North Queensland in 1982.
Detectives have refused to confirm if they have a prime suspect in the 32-year-old investigation but claim they are close to cracking the case.
"I told police Albury was active in northwest Queensland," Chapman said.
"He's a prime suspect. If it's not him, it has to be someone in the same category, but there are very few psychopaths on the planet as dangerous as him. He's a real-life Hannibal Lecter."
