2/26/2026, 11:09:57 PM
Core Event: Allegations of Murder and Livestream Alibi
Stephen McCullagh, a 36-year-old YouTuber, is on trial for the alleged murder of his pregnant girlfriend, Natalie McNally, who was 15 weeks pregnant at the time of her death. The prosecution claims that McCullagh killed McNally at her home in Lurgan, Co Armagh, on December 18, 2022, while he was purportedly livestreaming himself playing video games from his home in Co Antrim. The trial is taking place at Belfast Crown Court and is expected to last around five weeks.
Evidence Presented: Livestream Analysis
During the trial, digital forensic analyst Detective Constable Matthews testified that an examination of McCullagh's computer indicated that the livestream was pre-recorded on December 14, 2022, and later broadcast as live on December 18. Matthews stated that the software used showed no user activity between 6 PM on December 18 and just after midnight on December 19, suggesting that McCullagh was not at home during the alleged time of the murder. The prosecution argues that McCullagh traveled to McNally's home, committed the murder, and returned home before making a 999 call later that night.
Details of the Alleged Crime
The court has heard that McNally, 32, suffered a prolonged assault, which included stab wounds to the neck, strangulation, and heavy blows to the head. The prosecution has characterized the murder as "planned, calculated, and premeditated," asserting that McCullagh intended to create an alibi through the livestream.
Criticism & Opposition: Defense Claims
McCullagh has denied the charges against him, and his defense is expected to challenge the prosecution's narrative, particularly the claims regarding the pre-recorded nature of the livestream. The defense may argue that the evidence does not conclusively prove McCullagh's involvement in McNally's death.
Official Statements & Responses
The prosecution has emphasized the significance of the digital evidence, stating that it paints a clear picture of McCullagh's actions leading up to the murder. Detective Constable Matthews noted, “Activity relating to video recording was taking place on the 14th... and finally the deletion of the said file in the early hours of the 19th, 2022.” This statement underscores the timeline that the prosecution is building against McCullagh.
What's Next: Continuation of the Trial
The trial continues as the court examines further evidence and testimonies. The outcome will depend on the jury's assessment of the evidence presented, including the digital forensic analysis and the circumstances surrounding McNally's death.
