Child killer back behind bars

A notorious Western Australia child killer who served 24 years for murdering a mother and son is back behind bars.

Robert Barry Pearce killed his ex-girlfriend and her son in 1984.

The boy, Jaime Dunderdale was stabbed more than 40 times.

Pearce was then involved in a 1990 plot to blow up the walls of Fremantle Prison.

There was a major controversy when Pearce was released from jail in 2008.

On Monday night he allegedly used a knife to threaten a service station worker in the Western Australia town of Albany, before stealing money and cigarettes.

Pearce handed himself into the Police and has been remanded in custody.
