PLEASE NOTE: The images published in full below are disturbing and could be triggering.
These are "live photos" of David Mackenzie, Thomas Kruger and some other boys. The pictures are believed to have been taken in Mackenzie’s flat in Espin House at St Andrew's College in Makhanda.
A "live photo" is really a short piece of video, because an iPhone takes a second’s footage before and after a picture is taken.
These images feature in episode 3 of the My Only Story podcast's second season.
