Reclusive cannabis addict De Zoysa was obsessed with weapons and watched violent videos on the internet.
He had been subjected to repeated beatings by his abusive father and appeared to be on the way to the family home with the loaded gun when he was arrested on September 25, 2020.
Asked if this was of significance, DAC Cundy said outside court: “Only De Zoysa knows why he was carrying a firearm on that night and whether he intended to use it or not."
