Stephen McCullagh was sentenced to 31 years in prison on Wednesday for the premeditated murder of his pregnant partner, Natalie McNally [1].

The case highlights the potential for digital manipulation in criminal activity, as the defendant attempted to use the perceived authenticity of a live broadcast to deceive investigators.

The murder occurred on the night of Dec. 18, 2022 [2]. To conceal the crime and establish a false alibi, McCullagh staged a six-hour prerecorded video and presented it as a live stream on YouTube [3].

Legal proceedings lasted three years, culminating in a trial that spanned five weeks [2]. The court found that the killing was premeditated and that the digital ruse was a calculated effort to avoid detection [3].

McNally was pregnant at the time of her death [4]. The crime took place at the home of McCullagh [5].

Following the conclusion of the trial on June 3, the court handed down the sentence of 31 years [1].

This conviction underscores the evolving nature of forensic evidence in the digital age. While the defendant attempted to use a prerecorded stream to simulate real-time presence, the failure of the alibi suggests that digital timestamps and metadata remain critical tools for investigators in debunking sophisticated online fabrications.
