Parents of Westfield Bondi murderer Joel Cauchi break their silence

The 'very religious' parents of the killer responsible for the Bondi Junction Westfield shopping centre massacre emerged from their home on Sunday evening after breaking their silence on the horrific stabbing spree.

Andrew and Michele Cauchi, both in their 70s, declined to speak with media after earlier describing their son Joel Cauchi's murderous rampage as 'truly horrific'.

A neighbour who has lived on the street for more than 30 years visited Mrs Cauchi for about an hour, while a man believed to be a family member was also at the house helping Mr Cauchi with his pigeon coops.
