Stephen McCullagh, 36, was accused of murdering his pregnant partner, Natalie McNally, on December 18, 2022. He claimed to be livestreaming a gaming session as an alibi, appearing to be in Lisburn while the murder occurred in Lurgan. The Police Service of Northern Ireland's cyber crime unit investigated and found that the livestream was pre-recorded on December 14, 2022. During the trial, sections of the six-hour livestream were shown, where McCullagh appeared intoxicated while playing video games. He later admitted to pre-recording the footage and consuming alcohol on the night of the murder. The trial revealed extensive digital evidence that contradicted his alibi, leading to his re-arrest in January 2023. The case highlights the role of digital evidence in criminal investigations, particularly in debunking false alibis.
