The murders of Phyllis Harrison in 1998, Beverley Hanley in 2010 and Stephen Newton, whose badly decomposed body was found in 2011, have been the subject of Task Force Resolute, established after fresh forensic evidence was uncovered.
“We now have proof that the same offender is responsible for all three deaths,” Detective Superintendent Des Bray said today.
The involvement of a single suspect had been considered before, but was not able to be fully proven until now.
“There has been speculation in the past that the same offender was involved, but now I can say we have proof and we believe theft was the motive in all three matters,” Bray said.
Police would like to speak to witnesses again and have urged them to come forward.
“We know that there are people who have provided incorrect or incomplete statements and I would urge them to come forward and speak with us,” Bray said.
