STEPHEN Mateer, one of the notorious paedophile identical twins who preyed on two young boys in Lake Macquarie more than 30 years ago, could spend the rest of his life behind bars for sexual abuse a judge labelled "brutal, calculated and selfish".
The Mateer twins, 71, who are now both believed to be suffering from a cognitive impairment, were found to have committed a string of sexual and indecent assaults against two young boys between 1989 and 1993 after a concurrent special hearing and judge-alone trial in Newcastle District Court last year.
