On a December night in 2022, Natalie McNally was stabbed to death in her home in Lurgan, County Armagh. She was 32 years old and 15 weeks pregnant. Her killer, the jury at Belfast Crown Court determined after deliberating in March 2026, was the man who had fathered that child — Stephen McCullagh, 36, of Woodland Gardens, Lisburn. This week, Mr Justice Kinney sentenced McCullagh to life imprisonment with a minimum tariff of 31 years, describing the attack as "brutal and frenzied" and assessing his culpability as "extremely high."

The alibi McCullagh constructed was, by any measure, audacious. While investigators pieced together the timeline of Natalie's death, McCullagh pointed to a YouTube livestream he had been broadcasting that evening — footage of himself, apparently at home, playing Grand Theft Auto. The implicit argument: he was on camera, in public view, how could he have been in Lurgan? It is the kind of logic that works only if nobody looks too closely at the mechanics of how livestreaming actually functions.

They looked. Digital forensic analysis dismantled the alibi. Investigators established that the stream had been pre-recorded and then broadcast as though it were live — a technical sleight of hand designed to place McCullagh, on screen, somewhere he was not. The gap between appearance and reality is the oldest trick in the book; McCullagh simply updated it for the platform era. The jury rejected his denial after examining the evidence and returned a guilty verdict.

What the judge's sentencing remarks make plain is that this was not a crime of sudden passion misread as something worse. The premeditation embedded in staging a false alibi before the act — not after, before — speaks to a level of deliberate intent that courts treat with particular gravity. You do not pre-record a gaming stream as cover unless you have already decided what you are going to do. Mr Justice Kinney's "extremely high" culpability assessment reflects exactly that calculus.

Natalie McNally's pregnancy compounds everything. Under Northern Irish law, as across the United Kingdom, the killing of a pregnant woman does not constitute a separate charge for the unborn child — the law in this jurisdiction has not moved to a foetal homicide framework. That legal architecture means the 31-year minimum must carry the weight of two deaths, even if the indictment names only one. It is a tension that Natalie's family and advocates have not been quiet about.

McCullagh's use of a public YouTube channel as an instrument of deception adds a dimension that courts have rarely had to confront so directly. The platform, in this reading, was not incidental — it was infrastructure for the crime. Tens of thousands of people who subscribed to watch gaming content were, without their knowledge, participants in an attempted cover-up. That the cover-up failed is a function of forensic capability catching up with platform technology faster than McCullagh anticipated.

Natalie McNally had been living alone in Lurgan when she was killed. She was discovered by family members who raised the alarm after she failed to respond to contact. The image that has circulated — a young woman, visibly pregnant, taken weeks before her death — has become the fixed point around which public reaction to this case has organised itself. Her family have spoken of a life and a pregnancy that should have been a beginning, not an ending.

The 31-year minimum means McCullagh will not be eligible for release consideration until he is in his late sixties, assuming standard parole timelines. Whether that constitutes justice proportionate to the crime is a question reasonable people answer differently. What is not in question is the verdict itself: a jury heard the full weight of the digital forensic evidence, the timeline reconstruction, and McCullagh's own denial — and they did not believe him. The stream was fake. The alibi was fake. The jury was not.
