The man who fatally stabbed six people in a Sydney shopping centre last April had a “preoccupation with death and murder” and made online searches for serial killers and the Columbine school shooters in the days before his attack, a court has heard.
It also heard that at the moment the attack began, the sole CCTV security room operator had been using the bathroom and re-entered the CCTV room less than two minutes later, towards the end of the man’s stabbing rampage.
