BELFAST – Stephen McCullagh, who used a pre-recorded YouTube gaming stream to manufacture an alibi for the murder of his pregnant partner, has lodged an appeal against his sentence.
The legal challenge comes after McCullagh was sentenced to life imprisonment at Belfast Crown Court earlier this month. The court determined he must serve a minimum of 31 years before he can be considered for parole.
The Public Prosecution Service (PPS), the agency responsible for conducting criminal prosecutions in Northern Ireland, has been formally notified that the appeal has been filed.
The Digital Alibi
The conviction centered on a sophisticated attempt to deceive investigators using digital media. On December 18, 2022, the night Natalie McNally was killed, McCullagh claimed he was broadcasting live on his YouTube channel, playing online games.
However, forensic police experts dismantled the alibi by proving the six-hour broadcast was not live. Investigations revealed the footage had been filmed four days prior and scheduled to air as a livestream, creating the illusion of his presence at a computer during the time of the murder.
Prosecutors said the use of a pre-recorded stream underscored emerging challenges for investigators and courts as social-media tools are deployed not just for communication, but as potential instruments to frustrate criminal inquiries.
Mr Justice Patrick Kinney described the staged broadcast as an “integral” part of the murder plan, stating the stream had been “carefully curated to appear as if it was streaming live and to provide the defendant a carefully planned complete alibi to the murder.”
Court Findings and Sentencing
McCullagh, of Woodland Gardens, Lisburn in Co Antrim, was found guilty by a jury of murdering Ms McNally at her home in Lurgan, Co Armagh. At the time of the attack, the 32-year-old victim was 15 weeks pregnant.
The court detailed the following parameters of the sentencing:
- Offence: Murder of Natalie McNally
- Sentence: Life imprisonment, the mandatory sentence for murder under the Justice Act (Northern Ireland) 2016
- Minimum Term (Tariff): 31 years before eligibility for parole consideration
- Jurisdiction: Belfast Crown Court, sitting in Northern Ireland’s Crown Court system
The judge’s determination of the minimum term follows statutory sentencing guidelines, taking into account aggravating factors including the vulnerability of the victim, the impact on her family, and the deliberate attempts to conceal the crime.
During the proceedings, Mr Justice Kinney characterized the killing as a “brutal and frenzied attack.”
“The defendant did not just kill Natalie McNally, her unborn child also died as a result of the murderous assault,” the judge said.
In establishing the 31-year minimum term, the judge noted that the legal penalty “cannot possibly reflect the value of Natalie’s life, or indeed that of her unborn child, Dean” or sufficiently address the “grief and loss” experienced by the family.
Appeal and Next Steps
The appeal has been lodged following the notification of the Public Prosecution Service. The case will now move to the Court of Appeal in Northern Ireland, where judges will examine whether the trial was conducted fairly and whether the sentence is consistent with applicable law and practice.
Any eventual ruling by the appellate court will be closely watched by legal practitioners and digital-forensics experts, amid a growing body of cases in which online content and platform tools – from scheduled livestreams to archived video – form a central part of the evidential record in serious criminal trials.
