Stephen McCullagh, who was sentenced to life imprisonment for the murder of his pregnant partner Natalie McNally, has officially lodged an appeal against his sentence. McCullagh, 34, admitted to the killing of 32-year-old Ms. McNally at her home in Silverwood Green, Lurgan, on December 18, 2022. Ms. McNally was 15 weeks pregnant at the time of her death.
Why is McCullagh appealing?
McCullagh is challenging the 31-year minimum term set by the court before he becomes eligible to apply for parole. In February 2024, at Belfast Crown Court, Mr. Justice O’Hara imposed the life sentence, noting the "cold-blooded, calculated" nature of the crime. The defense is seeking to have the duration of this custodial term reviewed by the Court of Appeal.
Legal proceedings confirmed that McCullagh had spent months meticulously planning the murder. To establish an alibi, he recorded a gaming livestream on the night of the killing, which he later broadcast to make it appear as though he were at home at the time of the attack. Police investigators later discovered the footage had been pre-recorded to deceive authorities.
The timeline of the investigation
The investigation into Ms. McNally’s death involved a significant forensic effort by the Police Service of Northern Ireland (PSNI). Detectives analyzed hours of CCTV footage and digital evidence to dismantle the alibi McCullagh had constructed.
Key evidence presented during the trial included:
- The fake livestream: McCullagh broadcast a video of himself playing a game for several hours on the night of December 18, 2022, to create a digital trail suggesting his presence at his own residence.
- CCTV evidence: Police tracked his movements through various camera networks, which contradicted his claims of being home.
- Forensic data: Digital analysis of his devices eventually forced a confession, as the evidence against him became insurmountable.
Legal context and sentencing standards
The 31-year tariff imposed by Mr. Justice O’Hara reflects the severity of the offense, specifically the "vicious and sustained" nature of the knife attack and the fact that the victim was pregnant. Under Northern Ireland law, a life sentence for murder carries a mandatory minimum term, but the specific duration is determined by the presiding judge based on aggravating factors.
In this case, the court identified multiple aggravating factors, including the breach of trust involved in killing a partner and the elaborate efforts taken to evade capture. The appeal process will now determine whether the Court of Appeal finds any legal basis to adjust the minimum term served.
Key takeaways
- Conviction: Stephen McCullagh pleaded guilty to the murder of Natalie McNally in December 2023.
- Sentence: He was handed a life sentence with a 31-year minimum term in February 2024.
- Status: The Court of Appeal has been notified of the intention to challenge the length of the sentence.

The appeal marks the latest development in a case that drew widespread public attention across Northern Ireland due to the calculated nature of the deception employed by the perpetrator. No date has been set for the appeal hearing.
