Crimes That Shook Australia

Peter Dupas (1x3)

:

On 19th April 1999, several times convicted criminal Peter Dupas posed as a new client of psychotherapist Nicky Patterson. Having made arrangements for his first appointment, 28-year-old Nicky welcomed Dupas into her home under the pretence that she would be giving him counselling for gambling. Dupas then attacked Nicky with a knife before mutilating her body. Evidence at the scene led police to Dupas. Dupas was sentenced to life in prison with no possibility of parole in August 2000 and was later found guilty of the separate 1997 murders of Margaret Maher and Mersina Halvagis and was given two more life sentences.
