Live Stream Killer

The film tells the chilling story of Natalie McNally’s murder and the extraordinary three-year investigation that followed - a case that redefines how technology can be used to both commit and conceal violent crime. On 18th December 2022, 32-year-old Natalie McNally returned to her home outside Belfast after watching the World Cup Final with her father. Just hours later, she was brutally murdered. At the same time, her boyfriend, Stephen McCullagh, appeared to be hosting a six-hour live-streamed gaming session online, providing what seemed to be an unbreakable alibi. Live Stream Killer reveals how the “live” broadcast was, in fact, pre-recorded days earlier, part of an elaborate and calculated plan to evade justice. Through meticulous digital forensics, investigators uncovered how McCullagh manipulated technology, movement, and timing to construct what may be a world-first alibi of its kind.
