In a case that has gripped Northern Ireland and sent shockwaves through communities both online and off, YouTuber Stephen McCullagh, 36, has been sentenced to life in prison for the murder of his pregnant partner, Natalie McNally. The verdict, delivered on Monday, March 23, 2026, at Belfast Crown Court, brought a dramatic end to a five-week trial marked by elaborate deceit, chilling premeditation, and a family’s long wait for justice.
Natalie McNally, 32, was 15 weeks pregnant when she was beaten, strangled, and stabbed in her own home in Silverwood Green, Lurgan, on the night of December 18, 2022. The father of her unborn son, McCullagh, meticulously plotted the crime and sought to cloak his actions beneath a digital smokescreen—a supposedly live gaming stream broadcast to his tens of thousands of YouTube followers.
The court heard that McCullagh’s plan was as cold-blooded as it was outlandish. According to BBC, on the afternoon of December 18, 2022, McCullagh announced to his subscribers that he would be hosting a live gaming event titled “Violent Night” from 6:00 pm. The stream, which showed him playing Grand Theft Auto: Vice City and Robot Wars, was presented as a real-time broadcast. Yet, as digital forensic analysts from the PSNI’s cyber crime team later revealed, the entire six-hour stream had been recorded days earlier, on the night of December 14 into the early hours of December 15.
Unusually, McCullagh told viewers he wouldn’t be able to interact or respond to comments due to technical problems—an oddity that, in hindsight, was a subtle but telling clue. While his digital persona entertained viewers, McCullagh was physically miles away, executing a plan that would end in tragedy. CCTV footage and witness accounts confirmed that McCullagh left his home in Lisburn, traveled by bus to Lurgan, and walked more than a mile to Natalie’s house, all while disguised in dark clothing, gloves, and a hat, his face partially hidden. He carried a green shopping bag, further obscuring his identity.
Between 8:50 pm and 9:30 pm, McCullagh attacked Natalie, inflicting fatal wounds—she was stabbed, strangled, and struck at least five times in the head. According to Armagh I, just prior to the attack, Natalie had been at her parents’ home enjoying Sunday dinner and watching the World Cup final. She and McCullagh exchanged messages; he said he was about to “stream the night away,” and she responded that she’d try to “sneak a peek at it.”
After the murder, McCullagh retraced his steps through Lurgan, this time captured by multiple CCTV cameras. He changed clothes along the way and, finding himself too late for public transport, flagged down a taxi by falsely claiming he had booked it. He directed the driver to his front gate in Lisburn. Upon arriving home, he stopped the pre-recorded stream and deleted the file just after midnight.
To further cement his alibi, McCullagh sent text messages to Natalie’s phone and to a friend, Anne, suggesting that Natalie was angry with him for drinking during her pregnancy and that she might be experiencing issues with her diabetes. He even posted a video review of a Star Wars lightsaber toy, as if nothing was amiss. The next evening, after no one had heard from Natalie, McCullagh went to her house and made a frantic 999 call at 9:59 pm. Sobbing, he told the operator, “Please come as soon as you can,” and, when prompted, “She’s pregnant… I think it’s 15 [weeks], we have a scan tomorrow.” He added, “She’s cold,” and “There’s blood everywhere.”
Prosecutors argued that this call was “an act, a put-on”—part of McCullagh’s elaborate plan to evade justice. Crown barrister Charles MacCreanor KC told the jury that McCullagh had “lied and lied again,” weaving a web of deceit that included attending Natalie’s wake, visiting her grave, messaging her family, and even secretly recording the McNally family’s private conversations at their home. According to BBC, McCullagh left his phone in the McNally home for nearly 40 minutes to capture their discussions, later claiming it was due to a technical glitch. The court also learned he had previously recorded a private counseling session of an ex-partner without her knowledge.
Throughout the trial, McCullagh maintained his innocence, refusing to take the stand. His defense, led by John Kearney KC, argued that Natalie’s ex-boyfriend was the real culprit. The jury heard that Natalie had been messaging other men in the months leading up to her death, including sexually explicit exchanges, and that she had told one man she was considering ending her relationship with McCullagh. The defense pointed to “gaps and holes” in the circumstantial case, noting the absence of direct identification evidence or gait analysis. Nonetheless, the jury was not convinced.
Key evidence included the forensic analysis of McCullagh’s computer, the CCTV footage tracking his movements, and the exposure of his false alibi. The jury of six men and six women deliberated for just over two hours before unanimously finding McCullagh guilty of murder. As the foreman delivered the verdict, Natalie’s family erupted in cheers and applause in the packed courtroom—a rare, emotional outpouring after years of grief and uncertainty.
Trial judge Mr. Justice Kinney addressed the court, saying, “I know it’s a very emotional time… but please, if you could just calm down.” Turning to McCullagh, he pronounced, “Stephen McCullagh, you have been convicted of the murder of Natalie McNally and for that offence I impose a sentence of life imprisonment on you. A date will be set for the settling of a minimum tariff on that sentence.” The tariff hearing is scheduled for May 15, 2026.
Before the court adjourned, Justice Kinney thanked the jury for their “diligence, commitment and patience” during what he called a “distressing” trial. He also praised the McNally family for the dignity they displayed throughout the proceedings and excused the jurors from future service, acknowledging the emotional toll the case had taken on all involved.
As McCullagh was led away in handcuffs, he passed the McNally family—standing, silent, but resolute. Their applause for the Crown’s legal team was a final gesture of gratitude for the justice they had long awaited. In the aftermath, the case stands as a stark reminder of the dangers of calculated deception and the resilience of a family in pursuit of truth.
