Cauchi fatally stabbed Pikria Darchia, 55, before being shot dead by NSW Police Insp Amy Scott, who had been on duty close by. Between the moment Insp Scott arrived and the moment she killed Cauchi just over a minute had passed, the court heard.

The man behind the Westfield Bondi Junction stabbing rampage stopped receiving treatment for serious mental health issues years before the terrifying attack, a court has been told.
